    The topical anti-inflammatory properties of flutrimazole, a new imidazole antifungal, have been evaluated. Flutrimazole inhibited mouse ear oedema induced by arachidonic acid, tetradecanoylphorbol-acetate and dithranol, with IC50 values of 3.32, 0.55 and 2.42 mumols/ear, respectively. Ketoconazole showed similar potency in arachidonic acid and dithranol models (IC50 = 3.76 and 2.41 mumols/ear) whereas it was less active against tetradecanoylphorbol acetate (IC50 = 1.96 mumols/ear). The standard anti-inflammatory sodium diclofenac was overall slightly more potent than antifungals (IC50 = 2.23, 0.57 and 0.57 mumols/ear against arachidonic acid, tetradecanoylphorbol acetate and dithranol, respectively). Both 2% flutrimazole and 2% ketoconazole creams, applied topically, inhibited carrageenan-induced rat paw oedema by about 40%. Under the same conditions, 1% flutrimazole and diclofenac creams inhibited by 26 and 54%, respectively. Flutrimazole may work through the inhibition of 5-lipoxygenase, as it inhibited LTB4 production by human granulocytes with an IC50 value of 11 microM (IC50 value for ketoconazole was 17 microM), whereas ram seminal vesicle cyclooxygenase was only inhibited by 16% at a concentration of 25 microM. Drugs such as flutrimazole, with dual anti-inflammatory/antifungal activity, may be advantageous in the treatment of topical fungal infections with an inflammatory component.

    The present study reports the chemical composition, antifungal, antioxidant and anti-inflammatory properties as well as the cytotoxicity of Oenanthe crocata essential oil and one of its main compounds. The essential oil was obtained from the aerial parts of the plant by hydrodistillation and analysed by GC and GC/MS. The oil was predominantly composed of monoterpene hydrocarbons (85.8%), being the main compounds trans-β-ocimene (31.3%), sabinene (29.0%) and cis-β-ocimene (12.3%). For the antifungal activity, the minimal inhibitory and minimal lethal concentrations (MICs and MLCs) were determined. The oil was particularly active against dermatophytes and Cryptococcus neoformans, with MIC values ranging from 0.08 to 0.16 μL/mL. Regarding the anti-inflammatory activity, both the oil and sabinene demonstrated strong anti-inflammatory activity through nitric oxide (NO) production inhibition in lipopolysaccharide (LPS) plus interferon gamma (IFN-γ)-triggered macrophages. Furthermore, the essential oil showed a potent NO scavenging effect and inhibited inducible NO synthase expression. Interestingly, and although we detected a cytotoxic effect in macrophages and keratinocytes for the highest concentrations tested of the oil and sabinene, we also disclosed bioactive and safe concentrations to be further explored for therapeutic proposes. Taking together, these results support the use of the oil and sabinene for the management of dermatophytosis and/or inflammatory-related diseases.

    Full Text Available Background: Volatile oils obtained from lemon grass [Cymbopogon citratus (DC. Stapf, Poaceae family] are used in traditional medicine as remedies for the treatment of various diseases. Aims: In the present study, lemon grass essential oil (LGEO was evaluated for its in vivo topical and oral anti-inflammatory effects, and for its in vitro antifungal activity using both liquid and vapor phases. Methods: The chemical profile of LGEO as determined by gas chromatography–mass spectrometry analysis revealed two major components: geranial (42.2%, and neral (31.5%. The antifungal activity of LGEO was evaluated against several pathogenic yeasts and filamentous fungi using disc diffusion and vapor diffusion methods. Results: LGEO exhibited promising antifungal effect against Candida albicans, C. tropicalis, and Aspergillus niger, with different inhibition zone diameters (IZDs (35–90 mm. IZD increased with increasing oil volume. Significantly, higher anti-Candida activity was observed in the vapor phase. For the evaluation of the anti-inflammatory effect, LGEO (10 mg/kg, administered orally significantly reduced carrageenan-induced paw edema with a similar effect to that observed for oral diclofenac (50 mg/kg, which was used as the positive control. Oral administration of LGEO showed dose-dependent anti-inflammatory activity. In addition, topical application of LGEO in vivo resulted in a potent anti-inflammatory effect, as demonstrated by using the mouse model of croton oil-induced ear edema. To our knowledge, this is the first such report to be published. The topical application of LGEO at doses of 5 and 10 µL/ear significantly reduced acute ear edema induced by croton oil in 62.5 and 75% of the mice, respectively. In addition, histological analysis clearly confirmed that LGEO inhibits the skin inflammatory response in animal models. Conclusion: Results of the present study indicate that LGEO has a noteworthy potential for the development of drugs for

    Full Text Available Salvia officinalis L. (Lamiaceae is a Mediterranean species, naturalized in many countries. In Jordan, it is used in traditional medicine as antiseptic, antiscabies, antisyphilitic, and anti-inflammatory, being frequently used against skin diseases. This study aimed the assessment of the antifungal and anti-inflammatory potential of its essential oils, and their cytotoxicity on macrophages and keratinocytes. The oils were investigated by gas chromatography and gas chromatography-mass spectrometry and the antifungal activity was evaluated against yeasts, dermatophyte and Aspergillus strains. Assessment of cell viability was made by the 3-(4,5-dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide assay and the in vitro anti-inflammatory potential was evaluated by measuring nitric oxide production using lipopolysaccharide-stimulated mouse macrophages. The main compounds of S. officinalis oils were 1,8-cineole (39.5–50.3% and camphor (8.8–25.0%. The oils revealed antifungal activity against dermatophyte strains and significantly inhibited NO production stimulated by LPS in macrophages, without affecting cell viability, in concentrations up to 0.64 μL/mL. This is the first report addressing the in vitro anti-inflammatory potential of S. officinalis oil. These findings demonstrated that bioactive concentrations of S. officinalis oils do not affect mammalian macrophages and keratinocytes viability making them suitable to be incorporated in skin care formulations for cosmetic and pharmaceutical purposes.

    Full Text Available In this study, we examined anti-fungal and anti-inflammatory effects of the synthetic melanocortin peptide (Ac-Cys-Lys-Pro-Val-NH22 or (CKPV2 against Candida albicans vaginitis. Our in vitro results showed that (CKPV2 dose-dependently inhibited Candida albicans colonies formation. In a rat Candida albicans vaginitis model, (CKPV2 significantly inhibited vaginal Candida albicans survival and macrophages sub-epithelial mucosa infiltration. For mechanisms study, we observed that (CKPV2 inhibited macrophages phagocytosis of Candida albicans. Meanwhile, (CKPV2 administration inhibited macrophage pro-inflammatory cytokines (TNF-α, IL-1β and IL-6 release, while increasing the arginase activity and anti-inflammatory cytokine IL-10 production, suggesting macrophages M1 to M2 polarization. Cyclic AMP (cAMP production was also induced by (CKPV2 administration in macrophages. These above effects on macrophages by (CKPV2 were almost reversed by melanocortin receptor-1(MC1R siRNA knockdown, indicating the requirement of MC1R in the process. Altogether, our results suggest that (CKPV2 exerted anti-fungal and anti-inflammatory activities against Candida albicans vaginitis probably through inducing macrophages M1 to M2 polarization and MC1R activation.

    Full Text Available Increasing drug resistance has brought enormous challenges to the management of Trichosporon spp. infections. The in vitro antifungal activities of non-steroidal anti-inflammatory drugs (NSAIDs against Candida spp. and Cryptococcus spp. were recently discovered. In the present study, the in vitro interactions between three NSAIDs (aspirin, ibuprofen and diclofenac sodium and commonly used antifungal agents (fluconazole, itraconazole, voriconazole, caspofungin and amphotericin B against planktonic and biofilm cells of T. asahii were evaluated using the checkerboard microdilution method. The spectrophotometric method and the XTT reduction assay were used to generate data on biofilm cells. The fractional inhibitory concentration index (FICI and the ΔE model were compared to interpret drug interactions. Using the FICI, the highest percentages of synergistic effects against planktonic cells (86.67% and biofilm cells (73.33% were found for amphotericin B/ibuprofen, and caspofungin/ibuprofen showed appreciable percentages (73.33% for planktonic form and 60.00% for biofilm as well. We did not observe antagonism. The ΔE model gave consistent results with FICI (86.67%. Our findings suggest that amphotericin B/ibuprofen and caspofungin/ibuprofen combinations have potential effects against T. asahii. Further in vivo and animal studies to investigate associated mechanisms need to be conducted.

  10. Anti-inflammatory Diets.

    Chronic disease is driven by inflammation. This article will provide an overview on how the balance of macronutrients and omega-6 and omega-3 fatty acids in the diet can alter the expression of inflammatory genes. In particular, how the balance of the protein to glycemic load of a meal can alter the generation of insulin and glucagon and the how the balance of omega-6 and omega-3 fatty acids can effect eicosanoid formation. Clinical results on the reduction of inflammation following anti-inflammatory diets are discussed as well as the molecular targets of anti-inflammatory nutrition. To overcome silent inflammation requires an anti-inflammatory diet (with omega-3s and polyphenols, in particular those of Maqui). The most important aspect of such an anti-inflammatory diet is the stabilization of insulin and reduced intake of omega-6 fatty acids. The ultimate treatment lies in reestablishing hormonal and genetic balance to generate satiety instead of constant hunger. Anti-inflammatory nutrition, balanced 40:30:30 with caloric restriction, should be considered as a form of gene silencing technology, in particular the silencing of the genes involved in the generation of silent inflammation. To this anti-inflammatory diet foundation supplemental omega-3 fatty acids at the level of 2-3 g of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) per day should be added. Finally, a diet rich in colorful, nonstarchy vegetables would contribute adequate amounts of polyphenols to help not only to inhibit nuclear factor (NF)-κB (primary molecular target of inflammation) but also activate AMP kinase. Understanding the impact of an anti-inflammatory diet on silent inflammation can elevate the diet from simply a source of calories to being on the cutting edge of gene-silencing technology.

    We have studied whether the phase II metabolism of 19-norandrosterone, the most representative metabolite of 19-nortestosterone (nandrolone), can be altered in the presence of other drugs that are not presently included on the Prohibited List of the World Anti-Doping Agency. In detail, we have evaluated the effect of non-prohibited drugs belonging to the classes of anti-fungals, benzodiazepines, and non-steroidal anti-inflammatory drugs on the glucuronidation of 19-norandrosterone. In vitro assays based on the use of either pooled human liver microsomes or specific recombinant isoforms of uridine diphosphoglucuronosyl-transferase were designed and performed to monitor the formation of 19-norandrosterone glucuronide from 19-norandrosterone. Determination of 19-norandrosterone (free and conjugated fraction) was performed by gas chromatography - mass spectrometry after sample pretreatment consisting of an enzymatic hydrolysis (performed only for the conjugated fraction), liquid/liquid extraction with tert-butylmethyl ether, and derivatization to form the trimethylsilyl derivative. In parallel, a method based on reversed-phase liquid chromatography coupled to tandem mass spectrometry in positive electrospray ionization with acquisition in selected reaction monitoring mode was also developed to identify the non-prohibited drugs considered in this study. Incubation experiments have preliminarily shown that the glucuronidation of 19-norandrosterone is principally carried out by UGT2B7 (39%) and UGT2B17 (31%). Inhibition studies have shown that the yield of the glucuronidation reaction is reduced in the presence of the anti-fungals itraconazole, ketoconazole, and miconazole, of the benzodiazepine triazolam and of the non-steroidal anti-inflammatory drugs diclofenac and ibuprofen, while no alteration was recorded in the presence of all other compounds considered in this study.

    Freek J. Zijlstra

    2003-01-01

    Full Text Available Acupuncture has a beneficial effect when treating many diseases and painful conditions, and therefore is thought to be useful as a complementary therapy or to replace generally accepted pharmacological intervention. The attributive effect of acupuncture has been investigated in inflammatory diseases, including asthma, rhinitis, inflammatory bowel disease, rheumatoid arthritis, epicondylitis, complex regional pain syndrome type 1 and vasculitis. Large randomised trials demonstrating the immediate and sustained effect of acupuncture are missing. Mechanisms underlying the ascribed immunosuppressive actions of acupuncture are reviewed in this communication. The acupuncture-controlled release of neuropeptides from nerve endings and subsequent vasodilative and anti-inflammatory effects through calcitonine gene-related peptide is hypothesised. The complex interactions with substance P, the analgesic contribution of β-endorphin and the balance between cell-specific pro-inflammatory and anti-inflammatory cytokines tumour necrosis factor-α and interleukin-10 are discussed.

    The ketogenic diet (KD) is an established treatment for refractory epilepsy, including some inflammation-induced epileptic encephalopathies. In a lipopolysaccharide (LPS)-induced fever model in rats, we found that animals given the KD for 14 days showed less fever and lower proinflammatory cytokine levels than control animals. However, KD rats exhibited a decrease in circulating levels of arachidonic acid and long-chain n-3 polyunsaturated fatty acids (PUFAs), suggesting that the anti-inflammatory effect of KD was probably not due to an increase in anti-inflammatory n-3 PUFA derivatives. These properties might be of interest in some conditions such as fever-induced refractory epileptic encephalopathy in school-aged children.

Plant extract 1:1 (w:v was prepared from A. ursinum leaves by a modified Squibb repercolation method. The in vivo anti-inflammatory effects were evaluated on a rat turpentine oil-induced inflammation (i.m. 6 mL/kg BW. The animals were randomly assigned to nine groups (n=8: negative control, inflammation, A. ursinum flower extract (AUF, A. ursinum leaves extract (AUL, indomethacin (INDO (20 mg/kg BW, aminoguanidine (AG (50 mg/kg b.w./d i.p. as a selective NOS2 inhibitor, NG-nitro L-arginine methyl ester (NAME (5 mg/kg b.w./d i.p. as a nonselective NOS inhibitor, L-arginine (ARG (100 mg/kg b.w./d i.p., NO synthesis substrate, and Trolox (20 mg/kg b.w./d i.p as an antioxidant. At 24h from inflammation induction total oxidative status (TOS, oxidative stress index (OSI, nitric oxide (NOx and in vitro phagocytosis test were reduced and the total antioxidative reactivity (TAR was increased by the testes plant extracts. AUF had a better inhibitory effect than AUL. In conclusion, we provided evidence for the hypothesis that A. ursinum leaves and flowers extract exerts anti-inflammatory activity by inhibiting the phagocytosis through the reduction of the nitro-oxidative stress.

    Full Text Available The current paper investigated the potential benefit of the traditional Mexican medicinal plant Laennecia confusa (Cronquist G. L. Nesom (Asteraceae. Fractions from the hexane, chloroform, methanol, and aqueous extracts were analyzed for antibacterial, antifungal, anti-inflammatory, and antiparasitic activities. The antimicrobial activity of the extracts and fractions was assessed on bacterial and fungal strains, in addition to the protozoa Leishmania donovani, using a microdilution assay. The propensity of the plant's compounds to produce adverse effects on human health was also evaluated using propidium iodine to identify damage to human macrophages. The anti-inflammatory activity of the extracts and fractions was investigated by measuring the secretion of interleukin-6. Chemical analyses demonstrated the presence of flavonoids, cyanogenic and cardiotonic glycosides, saponins, sesquiterpene lactones, and triterpenes in the chloroform extract. A number of extracts and fractions show antibacterial activity. Of particular interest is antibacterial activity against Staphylococcus aureus and its relative methicillin-resistant strain, MRSA. Hexanic and chloroformic fractions also exhibit antifungal activity and two extracts and the fraction CE 2 antiparasitic activity against Leishmania donovani. All bioactive extracts and fractions assayed were also found to be cytotoxic to macrophages. In addition, the hexane and methane extracts show anti-inflammatory activity by suppressing the secretion of interleukine-6.

    Erdosteine is a multifactorial drug currently used in COPD for its rheologic activity on bronchial secretions and its positive effects on bacterial adhesiveness. Erdosteine produces an active metabolite (Met 1) which was shown to produce antioxidant effects during the respiratory burst of human PMNs, due to the presence of an SH group. The substantial antitussive effects of erdosteine were first documented in clinical trials even though mucolytic agents are regarded as not consistently effective in ameliorating cough in patients with bronchitis, although they may be of benefit to this population in other ways. Actually, a mucolytic drug could exert antitussive effects if it also affects mucus consistency and enhances ciliary function. In the last decade, data from several studies on animal models pointed to the possible antitussive and anti-inflammatory properties of erdosteine and an indirect anti-inflammatory mechanism of action was suggested. Recently, data from some controlled versus placebo studies documented the antioxidant properties of erdosteine in humans and in current smokers with COPD. The mechanism of action was described as related to erdosteine's ability to inhibit some inflammatory mediators and some pro-inflammatory cytokines that are specifically involved in oxidative stress. As oxidative stress is also presumed to impair beta-adrenoceptor function and contribute to airway obstruction, specific controlled studies recently investigated the effect of antioxidant intervention on short-term airway response to salbutamol in nonreversible COPD, according to a double-blind design versus placebo and NAC. Only erdosteine consistently restored a significant short-term reversibility in COPD subjects, previously unresponsive to beta(2) adrenergics. This peculiar activity of erdosteine (to our knowledge never previously assessed) proved related to the ROS scavenging activity (which actually proved equal to that of N), and its significant inhibiting effect on

    Full Text Available Non-steroidal anti-inflammatory drugs (NSAIDs are often used in the treatment of chronic and acute pain and inflammation as an analgesic and anti-inflammatory agent. They inhibit the synthesis of prostaglandins which have influence on glomerular capillaries, vasa recta and tubular functions. They lead to significant complications such as hyperkalemia, hyponatremia, edema and hypertension. Usage of NSAIDs is a risk factor for acute kidney injury in some conditions such as advanced age, dehydration, vomiting, diuretics, ACE/ARB therapy, heart failure, nephrotic syndrome, cirrhosis and chronic kidney disease. Acute interstitial nephritis is not dependent on the drug dose and it is characterized by immunological inflammatory reaction and a decrease in creatinine clearance. Besides the classical findings, glomerules can be involved and minimal change disease or membranous glomerulonephritis can develop. Analgesic nephropathy is characterized by interstitial nephritis and papillary necrosis. Metabolites of NSAIDs are accumulated in renal medulla which has lowest oxygen pressure in kidney and they disrupt the renal parencymal perfusion by vasoconstriction. Respectively, papillar necrosis, glomerular sclerosis, interstitial fibrosis and cortical atrophy can develop insidiously.

This study evaluated in vitro cytotoxic and anti-inflammatory effects of S. persica extracts on human oral Jurkat (T leukemia cells. Extracts from Meswak stick and leaves were tested in different concentrations for their cytotoxic and anti-inflammatory activities on human oral Jurkat T- cells. So treated cells viability with increasing concentrations of S. persica stick extract (0.008-0.2 μg/ml and leaves extract (0.016-0.5 μg/ml for 24, 48 or 72 hours was assessed by using the mitochondrial dependent reduction of yellow MTT (3-[4, 5-dimethylthiazol-2-yl]-2, 5-diphenyl tetrazolium bromide to purple formazan. Also Enzyme-linked immunosorbent assay (ELISA was performed on supernatants from treated Jurkat T-cells with phytohemagglutinin (PHA and both extracts to quantify IL-6, IL-8 pro-inflammatory cytokines. Statistically significant differences were indicated by p <0.05. Incubation of Jurkat cells with sterile distilled water, negative control, didn't show any mortality through the incubation period. Against PHA, positive control, both stick and leaves extracts of S. persica like resulted in a dose-dependent decrease of IL-6 and IL-8 secretion (p <0.01. Although both extracts significantly inhibited survival of Jurkat cells (p < 0.01 in a dose- and time-dependent manner, stick extract exerted more cytotoxic effects on Jurkat cells than leaves extract of S. persica (p <0.03. In conclusion, although with increasing concentrations of both extracts anti-inflammatory properties were boosted, S. persica extracts had dose-dependent cytotoxic effects on human oral Jurkat T-cells.

    Taraxacum officinale has been widely used as a folkloric medicine for the treatment of diverse diseases. The dried plant was extracted with 70% ethanol to generate its ethanol extract (TEE). For some experiments, ethyl acetate (EA), n-butanol (BuOH) and aqueous (Aq) fractions were prepared in succession from TEE. TEE showed a scavenging activity in the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay, a diminishing effect on intracellular reactive oxygen species (ROS) level, and an anti-angiogenic activity in the chicken chorioallantoic (CAM) assay. In the carrageenan-induced air pouch model, TEE inhibited production of exudate, and significantly diminished nitric oxide (NO) and leukocyte levels in the exudate. It also possessed an inhibitory effect on acetic acid-induced vascular permeability and caused a dose-dependent inhibition on acetic acid-induced abdominal writhing in mice. Suppressive effects of TEE on the production of NO and expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in lipopolysaccharide (LPS)-stimulated macrophages were also assessed. Among the fractions, the n-butanol fraction (BuOH) was identified to be most effective in the CAM assay. Collectively, Taraxacum officinale contains anti-angiogenic, anti-inflammatory and anti-nociceptive activities through its inhibition of NO production and COX-2 expression and/or its antioxidative activity.

    Cannabinoids are a group of compounds that mediate their effects through cannabinoid receptors. The discovery of Δ9-tetrahydrocannabinol (THC) as the major psychoactive principle in marijuana, as well as the identification of cannabinoid receptors and their endogenous ligands, has led to a significant growth in research aimed at understanding the physiological functions of cannabinoids. Cannabinoid receptors include CB1, which is predominantly expressed in the brain, and CB2, which is primarily found on the cells of the immune system. The fact that both CB1 and CB2 receptors have been found on immune cells suggests that cannabinoids play an important role in the regulation of the immune system. Recent studies demonstrated that administration of THC into mice triggered marked apoptosis in T cells and dendritic cells, resulting in immunosuppression. In addition, several studies showed that cannabinoids downregulate cytokine and chemokine production and, in some models, upregulate T-regulatory cells (Tregs) as a mechanism to suppress inflammatory responses. The endocannabinoid system is also involved in immunoregulation. For example, administration of endocannabinoids or use of inhibitors of enzymes that break down the endocannabinoids, led to immunosuppression and recovery from immune-mediated injury to organs such as the liver. Manipulation of endocannabinoids and/or use of exogenous cannabinoids in vivo can constitute a potent treatment modality against inflammatory disorders. This review will focus on the potential use of cannabinoids as a new class of anti-inflammatory agents against a number of inflammatory and autoimmune diseases that are primarily triggered by activated T cells or other cellular immune components.

    Some plant proteases (e. g., papain, bromelain, ficin) have been used as anti-inflammatory agents for some years, and especially bromelain is still being used as alternative and/or complementary therapy to glucocorticoids, nonsteroidal antirheumatics, and immunomodulators. Bromelain is an extract rich in cysteine endopeptidases obtained from Ananas comosus. In this study the anti-inflammatory action of a partially purified extract of Bromelia hieronymi fruits, whose main components are cysteine endopeptidases, is presented. Different doses of a partially purified extract of B. hieronymi were assayed on carrageenan-induced and serotonine-induced rat paw edema, as well as in cotton pellet granuloma model. Doses with equal proteolytic activity of the partially purified extract and bromelain showed significantly similar anti-inflammatory responses. Treatment of the partially purified extract and bromelain with E-64 provoked loss of anti-inflammatory activity on carrageenan-induced paw edema, a fact which is consistent with the hypothesis that the proteolytic activity would be responsible for the anti-inflammatory action.

    Obestatin is a popular endogeneous peptide, known to have an autoimmune regulatory effect on energy metabolism and the gastrointestinal system. Studies regarding the anti-inflammatory effects of obestatin are scarce. The aim of this study was to show the anti-inflammatory effect of obestatin in an experimental model of autoimmune myocarditis in rats. Experimental autoimmune myocarditis was induced in Lewis rats by immunization with subcutaneous administration of porcine cardiac myosin, twice at 7-day intervals. Intraperitoneal pretreatment with obestatin (50 μg/kg) was started before the induction of myocarditis and continued for 3 weeks. The severity of myocarditis was evidenced by clinical, echocardiographic and histological findings. In addition, by-products of neutrophil activation, lipid peroxidation, inflammatory and anti-inflammatory cytokines were measured in serum. Obestatin significantly ameliorated the clinical and histopathological severity of autoimmune myocarditis. Therapeutic effects of obestatin in myocarditis were associated with reduced lipid peroxidation, suppression of polymorphonuclear leukocyte infiltration and enhancement of glutathione synthesis, inhibition of serum inflammatory and activation of anti-inflammatory cytokines. Histopathologically, the left ventricle was significantly dilated, and its wall thickened, along with widespread lymphocytic and histocytic infiltration. The myocardium was severely infiltrated with relatively large mononuclear cells. These histopathological changes were observed in lesser degrees in obestatin-treated rats. This study demonstrated a novel anti-inflammatory effect of obestatin in an experimental model of autoimmune myocarditis. Consequently, obestatin administration may represent a promising therapeutic approach for myocarditis and dilated cardiomyopathy in the future.

    It remains unknown whether newly identified anti-inflammatory/immunosuppressive cytokine interleukin-35 (IL-35) is different from other anti-inflammatory cytokines such as IL-10 and transforming growth factor (TGF)-β in terms of inhibition of inflammation initiation and suppression of full-blown inflammation. Using experimental database mining and statistical analysis methods we developed, we examined the tissue expression profiles and regulatory mechanisms of IL-35 in comparison to other anti-inflammatory cytokines. Our results suggest that in contrast to TGF-β, IL-35 is not constitutively expressed in human tissues but it is inducible in response to inflammatory stimuli. We also provide structural evidence that AU-rich element (ARE) binding proteins and microRNAs target IL-35 subunit transcripts, by which IL-35 may achieve non-constitutive expression status. Furthermore, we propose a new system to categorize anti-inflammatory cytokines into two groups: (1) the house-keeping cytokines, such as TGF-β, inhibit the initiation of inflammation whereas (2) the responsive cytokines including IL-35 suppress inflammation in full-blown stage. Our in-depth analyses of molecular events that regulate the production of IL-35 as well as the new categorization system of anti-inflammatory cytokines are important for the design of new strategies of immune therapies.

Evidence of these immunological changes include altered levels of cytokines and chemokines, changes in the numbers and activation states of various leukocyte populations, apoptosis, and fibrosis during diabetes. Therefore, treatment of diabetes and its complications may include pharmacological strategies to reduce inflammation. Apart from anti-inflammatory drugs, various hypoglycemic agents have also been found to reduce inflammation that could contribute to improved outcomes. Extensive studies have been carried out with thiazolidinediones (peroxisome proliferator-activated receptor- agonist, dipeptidyl peptidase-4 inhibitors, and metformin (AMP-activated protein kinase activator with each of these classes of compounds showing moderate-to-strong anti-inflammatory action. Sulfonylureas and alpha glucosidase inhibitors appeared to exert modest effects, while the injectable agents, insulin and glucagon-like peptide-1 receptor agonists, may improve secondary complications due to their anti-inflammatory potential. Currently, there is a lack of clinical data on anti-inflammatory effects of sodium–glucose cotransporter type 2 inhibitors. Nevertheless, for all these glucose-lowering agents, it is essential to distinguish between anti-inflammatory effects resulting from better glucose control and effects related to intrinsic anti-inflammatory actions of the pharmacological class of compounds.

    Full Text Available In this study, we evaluated the anti-inflammatory activity of one synthetic product, N-(3-Florophenylethylcaffeamide (abbrev. FECA, by using animal model of λ-carrageenan-induced paw edema in mice. The anti-inflammatory mechanism of FECA was determined by measuring the levels of cyclooxygenase-2 (COX-2, nitric oxide (NO, tumor necrosis factor (TNF-α, interleukin-1β (IL-1β, and malondialdehyde (MDA in the edema paw tissue, and the activities of superoxide dismutase (SOD, glutathione peroxidase (GPx, and glutathione reductase (GRd in the liver. The results showed that FECA reduced the paw edema at three, four and five hours after λ-carrageenan administration. The levels of COX-2, NO, TNF-α, and MDA in the λ-carrageenan-induced edema paws were reduced and the activities of SOD, GPx, and GRd in liver tissues were raised by FECA. These results suggested that FECA possessed anti-inflammatory activities and the anti-inflammatory mechanisms might be related to the decrease of the levels of COX-2, NO, and TNF-α in inflamed tissues and the increase in the MDA level by increasing the activities of SOD, GPx, and GRd.

    Full Text Available Smallanthus sonchifolius (Poepp. H. Rob. , Asteraceae, known as yacon, is an herb that is traditionally used for the treatment of diabetes in folk medicine. However, recent studies have demonstrated that this plant has other interesting properties such as anti-microbial and anti-inflammatory actions. Thus, the purpose of this study was to evaluate the topical anti-inflammatory property of different extracts prepared from yacon leaves and analyze the role of different chemical classes in this activity. Three yacon leaf extracts were obtained: aqueous extract, where chlorogenic acid derivatives and sesquiterpene lactones were detected; leaf rinse extract, rich in sesquiterpene lactones; and polar extract, rich in chlorogenic acid derivatives. All the extracts exhibited anti-edematogenic activity in vivo (aqueous extract: 25.9% edema inhibition at 0.50 mg/ear; polar extract: 42.7% inhibition at 0.25 mg/ear; and leaf rinse extract: 44.1% inhibition at 0.25 mg/ear. The leaf rinse extract furnished the best results regarding neutrophil migration inhibition, and NO, TNF-α and PGE2 inhibition. These data indicate that both sesquiterpene lactones and chlorogenic acid derivatives contribute to the anti-inflammatory action, although sesquiterpene lactones seem to have more pronounced effects. In conclusion, yacon leaf extracts, particularly the sesquiterpene lactone-rich extract, has potential use as topical anti-inflammatory agent.

    The monocyte locomotion inhibitory factor (MLIF), a heat-stable oligopeptide found in the supernatant fluid of Entamoeba histolytica axenic cultures, may contribute to the delayed inflammation observed in amoebic hepatic abscess. This factor was isolated by ultra-filtration and high powered liquid chromatography, obtaining a primary Met-Gln-Cys-Asn-Ser structure, identified afterwards as the carboxyl-terminal (…Cys-Asn-Ser) active site. The selective anti-inflammatory effects of the pentapeptide have been observed in both in vitro and in vivo models, using a synthetic pentapeptide to maintain the same anti-inflammatory conditions during the experimental assays. Anti-inflammatory effects observed include inhibition of human monocyte locomotion and the respiratory burst in monocytes and neutrophils, increasing expression of anti-inflammatory cytokines and inhibiting expression of the adhesion molecules VLA-4 and VCAM, among others. In this review, we will describe the effects of MLIF detected so far and how it might be used as a therapeutical agent against inflammatory diseases.

    Medicinal mushrooms have been essential components of traditional Chinese herbal medicines for thousands of years, and they protect against diverse health-related conditions. The components responsible for their anti-inflammatory activity have yet to be fully studied. This study investigates the anti-inflammatory activity of n-hexane, chloroform, ethyl acetate, and methanol extracts of mycelia in submerged culture from 5 commercially available medicinal mushrooms, namely Cephalosporium sinensis, Cordyceps mortierella, Hericium erinaceus, Ganoderma lucidum, and Armillaria mellea. MTT colorimetric assay was applied to measure the cytotoxic effects of different extracts. Their anti-inflammatory activities were evaluated via inhibition against production of lipopolysaccharide (LPS)-induced nitric oxide (NO) in murine macrophage-like cell line RAW264.7 cells. Of the 20 extracts, n-hexane, chloroform, ethyl acetate, and methanol extracts from C. sinensis, C. mortierella, and G. lucidum; chloroform extracts from H. erinaceus and A. mellea; and ethyl acetate extracts from A. mellea at nontoxic concentrations (mushrooms exhibited anti-inflammatory activity that might be attributable to the inhibition of NO generation and can therefore be considered a useful therapeutic and preventive approach to various inflammation-related diseases.

    The inflammatory response is a highly regulated process, and its dysregulation can lead to the establishment of chronic inflammation and, in some cases, to death. Inflammation is the cause of several diseases, including rheumatoid arthritis, inflammatory bowel diseases, multiple sclerosis, and asthma. The search for agents inhibiting inflammation is a great challenge as the inflammatory response plays an important role in the defense of the host to infections. Marine invertebrates are exceptional sources of new natural products, and among those diterpenoids secondary metabolites exhibit notable anti-inflammatory properties. Novel anti-inflammatory diterpenoids, exclusively produced by marine organisms, have been identified and synthetic molecules based on those structures have been obtained. The anti-inflammatory activity of marine diterpenoids has been attributed to the inhibition of Nuclear Factor-κB activation and to the modulation of arachidonic acid metabolism. However, more research is necessary to describe the mechanisms of action of these secondary metabolites. This review is a compilation of marine diterpenoids, mainly isolated from corals, which have been described as potential anti-inflammatory molecules. PMID:26538822

    Full Text Available In the present study, methanolic extract of Ipomoea reniformis herb (MEIR in acute, subacute and chronic models of inflammation was assessed in rats. Administration of MEIR (200, 400 mg/kg, p.o. exhibited significant anti-inflammatory activity. In acute inflammation as produced by Carrageenan 59.55 % and 64.04 % protection was observed. While in subacute anti-inflammatory models using formaldehyde-induced hind paw edema (after 1.5 h 38.36 % and 47.95 % and in chronic anti-inflammatory model using cotton pellet granuloma 15.02 % and 19.19 % protection from inflammation was observed. MEIR did not show any sign of toxicity and mortality up to a dose level of 1000 mg/kg, p.o. in rats. The results obtained suggest that the methanolic extract of Ipomoea reniformis herb (MEIR is endowed with effective anti-inflammatory activity mediated via either by inhibition of cyclooxygenase cascade and by blocking the release of vasoactive substances (histamine, serotonin and kinins. These findings seem to justify the use of the plant in traditional Indian medicine in the treatment of inflammation, including arthritic conditions.

    Inflammation often plays a key role in the perpetuation of pain. Chronic inflammatory conditions (e.g. osteoarthritis, immune system dysfunction, micro-circulatory disease, painful neuritis, and even heart disease) have increased as baby boomers age. Medicine's current anti-inflammatory choices are NSAIDs and steroids; the value in promoting cure and side effect risks of these medications are unclear and controversial, especially considering individual patient variations. Electricity has continuously been a powerful tool in medicine for thousands of years. All medical professionals are, to some degree, aware of electrotherapy; those who directly use electricity for treatment know of its anti-inflammatory effects. Electronic signal treatment (EST), as an extension of presently available technology, may reasonably have even more anti-inflammatory effects. EST is a digitally produced alternating current sinusoidal electronic signal with associated harmonics to produce theoretically reasonable and/or scientifically documented physiological effects when applied to the human body. These signals are produced by advanced electronics not possible even 10 to 15 years ago. The potential long-lasting anti-inflammatory effects of some electrical currents are based on basic physical and biochemical facts listed in the text below, namely that of stimulating and signaling effective and long-lasting anti-inflammatory effects in nerve and muscle cells. The safety of electrotherapeutic treatments in general and EST in particular has been established through extensive clinical use. The principles of physics have been largely de-emphasized in modern medicine in favor of chemistry. These electrical treatments, a familiar application of physics, thus represent powerful and appropriate elements of physicians' pain care armamentaria in the clinic and possibly for prescription for use at home to improve overall patient care and maintenance of quality of life via low-risk and potentially

    Boswellia carterii (BC) Birdwood oleogum resin is an ancient remedy of inflammation processes known since Ancient Egyptian time. Of boswellic acids, 3-acetyl-11-keto-β-boswellic acid (AKBA) is the most potent anti-inflammatory active principle. Liquisolid systems of the biologically active fraction of BC oleogum resin were prepared for improving dissolution properties using low dose oral delivery to achieve enhanced anti-inflammatory activity, in comparison with the standard oral anti-inflammatory; Indomethacin. AKBA was assayed, employing an accurate and sensitive HPLC method. Detection was carried out at 210 nm using UV/Vis detector. A solubility study for the bioactive fraction was conducted. Microcrystalline cellulose and Aeroperl®300 Pharma were used as carrier and coating materials. Angle of slide, liquid load factor and Carr's flow index were estimated. Six systems were prepared using polyethylene glycol 400, solvent and two drug loading concentrations; 20 and 40 %. For each concentration, three carrier: coat ratios were dispensed; 20:1, 10:1, and 5:1. Dissolution study was performed and two systems were selected for characterization and in vivo evaluation by investigating upper GIT ulcerogenic effect and anti-inflammatory efficacy in rats. Results indicate absence of ulcers and significantly higher and prolonged anti-inflammatory efficacy for formulations F1 and F2, with carrier: coat ratio, 5:1 and drug loads of 20 and 40 %, respectively, compared with standard oral indomethacin. We conclude higher efficacy of BC bioactive fraction liquisolids compared with Indomethacin with greater safety on GIT, longer duration of action and hence better patient compliance.

    As a part of our continuing investigation of the manzamine alkaloids we studied the in vitro activity of the β-carboline containing manzamine alkaloids against Fusarium solani, Fusarium oxysporium, and Fusarium proliferatum by employing several bioassay techniques including one-dimensional direct bioautography, dilution, and plate susceptibility, and microtiter broth assays. In addition, we also studied the metabolism of the manzamine alkaloids by Fusarium spp. in order to facilitate the redesign of the compounds to prevent resistance of Fusarium spp. through metabolism. The present research reveals that the manzamine alkaloids are inactive against Fusarium spp. and the fungi transform manzamines via hydrolysis, reduction, and a retro Pictet-Spengler reaction. This is the first report to demonstrate an enzymatically retro Pictet-Spengler reaction. The results of this study reveal the utility of the rational design of metabolically stable antifungal agents from this class and the development of manzamine alkaloids as antimalarial drugs through the utilization of Fusarium's metabolic products to reconstruct the molecule.

    Background: The plant species Bursera copallifera (DC) bullock is used in traditional medicine to treat inflammation. The leaves of this plant can be prepared as an infusion to treat migraines, bronchitis, and dental pain Objective: The purpose of this study was to determine the anti-inflammatory and cytotoxic activities of organic extracts from the stems, stem bark, and leaves of B. copallifera, which was selected based on the knowledge of its traditional use. Materials and Methods: We evaluated the ability of extracts to inhibit mouse ear inflammation in response to topical application of 12-O tetradecanoylphorbol-13-acetate. The extracts with anti-inflammatory activity were evaluated for their inhibition of pro-inflammatory enzymes. In addition, the in vitro cytotoxic activities of the organic extracts were evaluated using the sulforhodamine B assay. Results: The hydroalcoholic extract of the stems (HAS) exhibited an anti-inflammatory activity of 54.3% (0.5 mg/ear), whereas the anti-inflammatory activity of the dichloromethane-methanol extract from the leaves (DMeL) was 55.4% at a dose of 0.1 mg/ear. Methanol extract from the leaves (MeL) showed the highest anti-inflammatory activity (IC50 = 4.4 μg/mL), hydroalcoholic extract of leaves, and DMeL also reduce the enzyme activity, (IC50 = 6.5 μg/mL, IC50 = 5.7 μg/mL), respectively, from stems HAS exhibit activity at the evaluated concentrations (IC50 =6.4 μg/mL). The hydroalcoholic extract of the stems exhibited the highest cytotoxic activity against a breast adenocarcinoma cell line (MCF7, IC50 = 0.90 μg/mL), whereas DMeL exhibited an IC50 value of 19.9 μg/mL. Conclusion: In conclusion, extracts from leaves and stems inhibited cyclooxygenase-1, which is the target enzyme for nonsteroidal anti inflammatory drugs, and some of these extracts demonstrated substantial antiproliferative effects against the MCF7 cell line. These results validate the traditional use of B. copallifera. PMID:26664022

    Full Text Available Therapeutically potential prodrugs of piroxicam were synthesized by effective masking of enolic hydroxyl group through generation of ester congeners. The reaction facilitated using N,N′-dicyclohexylcarbodiimide coupled with acetic acid, benzoic acid, p-toluic acid, m-toluic acid, and cinnamic acid. Synthesized prodrugs were characterized for confirmation of the said structures. The modification of piroxicam showed better anti-inflammatory activity as evoked by all prodrugs. Interestingly, compound 3e, cinnamic acid ester prodrug, depicted 75 percent inhibition of rat paw edema as compared to 56 percent for parent piroxicam at 6 h of study. The present work proves the applicability not only with increased anti-inflammatory activity, but also with marked attenuation in ulcerogenicity. Novel prodrug 3e, cinnamic acid derivative, was found to be the least ulcerogenic having ulcer index of 0.67 as compared to parent drug piroxicam with 2.67.

    Boldine, an antioxidant alkaloid isolated from Peumus boldus, exhibits a dose-dependent anti-inflammatory activity in the carrageenan-induced guinea pig paw edema test with an oral ED50 of 34 mg/kg. Boldine also reduces bacterial pyrogen-induced hyperthermia in rabbits to an extent which varied between 51% and 98% at a dose of 60 mg/kg p.o. In vitro studies carried out in rat aortal rings revealed that boldine is an effective inhibitor of prostaglandin biosynthesis, promoting 53% inhibition at 75 microM. The latter in vitro effect may be mechanistically linked to the anti-inflammatory and antipyretic effects of boldine exerted in vivo.

    The underlying role of inflammation in atherosclerosis has been characterized. However, current treatment of coronary artery disease (CAD) predominantly consists of targeted reductions in serum lipoprotein levels rather than combating the deleterious effects of acute and chronic inflammation. Vascular inflammation acts by a number of different molecular and cellular pathways to contribute to atherogenesis. Over the last decades, both basic studies and clinical trials have provided evidence for the potential benefits of treatment of inflammation in CAD. During this period, development of pharmacotherapies directed towards inflammation in atherosclerosis has accelerated quickly. This review will highlight specific therapies targeting interleukin-1β (IL-1β), P-selectin and 5-lipoxygenase (5-LO). It will also aim to examine the anti-inflammatory effects of serpin administration, colchicine and intravenous HDL-directed treatment of CAD. We summarize the mechanistic rationale and evidence for these novel anti-inflammatory treatments at both the experimental and clinical levels.

    Oleaceae Forsythiae Fructus has been used for anti-inflammatory, diuretics, antidote, and antibacterials in traditional herbal medicine. Our previous screening of medicinal plants showed that methanol (MeOH) extract of Forsythiae Fructus had significant anti-inflammatory activity, but the active ingredients remain unclear. For isolation of active ingredient of MeOH extract of Forsythiae Fructus, it was partitioned with n-hexane and ethylacetate (EtOAc), and arctigenin was isolated from EtOAc fraction by column chromatography with anti-inflammatory activity-guided separation. Its activity was evaluated in the animal models of inflammation including myeloperoxidase (MPO) and eosinophil peroxidase (EPO) activities in the edematous tissues homogenate, and silica-induced reactive oxygen species (ROS) production in the RAW 264.7 cell line. It was shown that arctigenin (100 mg/kg) had significantly decreased not only carrageenan-induced paw edema 3 and 4h after injection of carrageenan, arachidonic acid (AA)-induced ear edema at a painting dose of 0.1-1.0mg/ear, and acetic acid-induced writhing response and acetic acid-induced capillary permeability accentuation at an oral dose of 25-100, and 100 mg/kg, respectively, but also MPO and EPO activities at a painting dose of 0.1-1.0mg/ear in the AA-induced edematous tissues homogenate as indicators of neutrophils and eosinophils recruitment into the inflamed tissue. Further, arctigenin (0.1-10 microM) also significantly inhibited the intracellular ROS production by silica. These results indicate that arctigenin is a bioactive agent of Forsythiae Fructus having significant anti-inflammatory action by inhibition of the exudation, and leukocytes recruitment into the inflamed tissues. The pharmacologic mechanism of action of arctigenin may be due to the inhibition of release/production of inflammatory mediators such as AA metabolites and free radicals.

    Over the last era, small molecules sourced from different plants have gained attention for their varied and long-term medicinal benefits. Their advantageous therapeutic effects in diverse pathological complications lead researchers to give an ever-increasing emphasis on them and discover their novel therapeutic potentials. Among these, the heat stable, xanthonoid group of organic molecules has gained special importance with distinctive regards to the bioactive molecule mangiferin due to its solubility in water. Mangiferin, a yellow polyphenol having C-glycosyl xanthone structure, is widely present in different edible sources like mango, and possesses numerous biological activities. Extensive research with this molecule shows its antioxidant, anti-inflammatory, antidiabetic, anticancer, antimicrobial, analgesic, and immunomodulatory properties. Thus, it provides protection against a wide range of physiological disorders. The C-glucosyl linkage and polyhydroxy groups in mangiferin's structure contribute essentially to its free radical-scavenging activity. Moreover, its ability in regulating various transcription factors like NF-κB, Nrf-2, etc. and modulating the expression of different proinflammatory signaling intermediates like tumor necrosis factor-α, COX-2, etc. contribute to its anti-inflammatory, anticancer, and antidiabetic potentials. In this comprehensive article, information has been provided about the sources, chemical structure, metabolism, and different biological activities of mangiferin with special emphasis on the underlying cellular signal transduction pathways. Insights into an in-depth assessment of mangiferin's anti-inflammatory therapeutic potential have also been discussed in detail. On an overall perspective, this review aims to stage mangiferin's diversified therapeutic applications and its emerging possibility as a promising drug in future based on its anti-inflammatory property. © 2016 BioFactors, 42(5):459-474, 2016.

    Thalidomide has anti-inflammatory, immunomodulatory, and anti-angiogenic properties. It has been used to treat a variety of cancers and autoimmune diseases. This study aimed to characterize anti-inflammatory activities of novel thalidomide analogs by exploring their effects on splenocytes proliferation and macrophage functions and their antioxidant activity. MTT assay was used to assess the cytotoxic effect of thalidomide analogs against splenocytes. Tumor necrosis factor (TNF-α) and nuclear factor kappa B (NF-κB-P65) were determined by enzyme-linked immunosorbent assay (ELISA). Nitric oxide (NO) was estimated by colorimetric assay. Antioxidant activity was examined by ORAC assay. Our results demonstrated that thalidomide dithioate analog 2 and thalidomide dithiocarbamate analog 4 produced a slight increase in splenocyte proliferation compared with thalidomide. Thalidomide dithiocarbamate analog 1 is a potent inhibitor of TNF-α production, whereas thalidomide dithiocarbamate analog 5 is a potent inhibitor of both TNF-α and NO. Analog 2 has a pronounced inhibitory effect on NF-κB-P65 production level. All thalidomide analogs showed prooxidant activity against hydroxyl (OH) radical. Analog 1 and thalidomide dithioate analog 3 have prooxidant activity against peroxyl (ROO) radical in relation to thalidomide. On the other hand, analog 4 has a potent scavenging capacity against peroxyl (ROO) radical compared with thalidomide. Taken together, the results of this study suggest that thalidomide analogs might have valuable anti-inflammatory activities with more pronounced effect than thalidomide itself.

    Every year more than a million new cancer cases and 600,000 deaths are reported world-wide. Colorectal cancer is the fourth most commonly occurring and second leading cause of cancer deaths in the United States. Significant progress has been made in understanding colorectal cancer through epidemiological, laboratory and clinical studies. Development of metastatic adenocarcinomas is a multistage process occurring over several years during which multiple genetic alterations and pathophysiological changes are associated. Colorectal cancer can be prevented if the transformation of normal colonic crypt cells to malignant can be halted or reversed. Some of the key molecules that are altered significantly and play important roles in colorectal tumor progression are associated with inflammation. Since chronic inflammation is now recognized as a potential risk factor for tumor development, targeting inflammatory pathways has proven effective in preventing formation of colonic tumors and their malignant progression in both preclinical and clinical studies. Synthetic non-steroidal anti-inflammatory drugs (NSAIDS) have been identified as potential colorectal cancer chemopreventive agents; however, most of these synthetic agents are associated with unwanted and sometimes fatal side effects. There is mounting evidence in support of the efficacy of naturally-occurring phytochemicals possessing anti-inflammatory activity. In this review we discuss key inflammatory pathways associated with colorectal cancer and promising naturally-occurring phytochemicals as anti-inflammatory agents for the prevention and treatment of colorectal cancer.

    Galphimia glauca, commonly known as "flor de estrella", is a plant species used in Mexican traditional medicine for the treatment of different diseases that have an acute or chronic inflammatory process in common. Aerial parts of this plant contain nor-seco-triterpenoids with anxiolytic properties, which have been denominated galphimines. Other compounds identified in the plant are tetragalloyl-quinic acid, gallic acid, and quercetin, which are able to inhibit the bronchial obstruction induced by platelet-activating factor. The objective of this work was to evaluate the anti-inflammatory effect of crude extracts from G. glauca and, by means of bioguided chemical separation, to identify the compounds responsible for this pharmacological activity. n-Hexane, ethyl acetate, dichloromethane, and methanol extracts showed an important anti-inflammatory effect. Chemical separation of the active methanol extract allowed us to identify the nor-seco-triterpenes galphimine-A (1) and galphimine-E (3) as the anti-inflammatory principles. Analysis of structure-activity relationships evidenced that the presence of an oxygenated function in C6 is absolutely necessary to show activity. In this work, the isolation and structural elucidation of two new nor-seco-triterpenes denominated as galphimine-K (4) and galphimine-L (5), together with different alkanes, fatty acids, as well as three flavonoids (17-19), are described, to our knowledge for the first time, from Galphimia glauca.

    Full Text Available Antarctic benthos was prospected in search for anti-inflammatory activity in polar benthic invertebrates, in two different geographical areas: deep-bottoms of the Eastern Weddell Sea and shallow-waters of the South Shetland Islands. A total of 36 benthic algae and invertebrate species were selected to perform solubility tests in order to test them for anti-inflammatory activity. From these, ethanol extracts of ten species from five different phyla resulted suitable to be studied in cell macrophage cultures (RAW 264.7. Cytotoxicity (MTT method and production of inflammatory mediators (prostaglandin E2, leukotriene B4, interleukin-1 were determined at three extract concentrations (50, 125, 250 g/mL. Bioassays resulted in four different species showing anti-inflammatory activity corresponding to three sponges: Mycale (Oxymycale acerata, Isodictya erinacea, and I. toxophila; and one hemichordate: Cephalodiscus sp. These results show that Antarctic sessile invertebrates may have great value as a source of lead compounds with potential pharmaceutical applications.

  12. Anti-inflammatory glucocorticoid drugs: reflections after 60 years.

    2011-02-01

    This review considers the problem of the serious concomitant side effects of powerful anti-inflammatory drugs modelled upon the principal human glucocorticoid hormone, cortisol. The very nature of the original bio-assays to validate their cortisol-like hormonal and anti-inflammatory activities ensured that pleiotropic toxins were selected for clinical studies. Other complicating factors have been (1) considerable reliance on bio-assays conducted in laboratory animals that primarily secrete corticosterone, not cortisol, as their principal anti-inflammatory adrenal hormone; (2) some differences in the binding of xenobiotic cortisol analogues (vis á vis cortisol) to transport proteins, detoxifying enzymes and even some intra-cellular receptors; (3) the "rogue" properties of these hormonal xenobiotics, acting independently of--but still able to suppress--hormonal mechanisms regulating endogenous cortisol; and (4) problems of intrinsic/acquired "steroid resistance", diminishing their clinical efficacy, but not necessarily all their toxicities. The rather gloomy conclusion is that devising new drugs to reproduce the effect of multi-potent hormones may be a recipe for disaster, in contexts other than simply remedying an endocrine deficiency. Promising new developments include "designed" combination therapies that allow some reduction in total steroid doses (and hopefully their side effects); sharpening strategies to limit the actual duration of steroid administration; and resurgent interest in searching for more selective analogues (both steroidal and non-steroid) with less harmful side effects. Some oversights and neglected areas of research are also considered. Overall, it now seems timely to engage in some drastic rethinking about (retaining?) these "licensed toxins" as fundamental therapies for chronic inflammation.

    A morroniside cinnamic acid conjugate was prepared and evaluated on E-selectin mediated cell-cell adhesion as an important role in inflammatory processes. 7-O-Cinnamoylmorroniside exhibited excellent anti-inflammatory activity (IC(50)=49.3 microM) by inhibiting the expression of E-selectin; further, it was more active than another cinnamic-acid-conjugated iridoid glycoside (harpagoside; IC(50)=88.2 microM), 7-O-methylmorroniside, and morroniside itself. As a result, 7-O-cinnamoylmorroniside was observed to be a potent inhibitor of TNF-alpha-induced E-selectin expression.

    Objective Ginger (Zingiber officinale) is widely used as a spice in cooking and as a medicinal herb in traditional herbal medicine. The present study was to investigate the analgesic and anti-inflammatory activities of ginger oil in experimental animal models. Methods The analgesic effect of the oils was evaluated by the "acetic acid" and "hot-plate" test models of pain in mice. The anti-inflammatory effect of the oil was investigated in rats, using rat paw edema induced by carrageenan, adjuvant arthritis, and vascular permeability induced by bradykinin, arachidonic acid, and histamine. Indomethacin (1 mg/kg), Aspirin (0.5 g/kg) and Dexamethasone (2.5 mg/kg) were used respectively as reference drugs for comparison. Results The ginger oil (0.25-1.0 g/kg) produced significant analgesic effect against chemically- and thermally-induced nociceptive pain stimuli in mice (P < 0.05, 0.01). And the ginger oil (0.25-1.0 g/kg) also significantly inhibited carrageenan-induced paw edema, adjuvant arthritis, and inflammatory mediators-induced vascular permeability in rats (P < 0.05, 0.001). Conclusion These findings confirm that the ginger oil can be used to treat pain and chronic inflammation such as rheumatic arthritis.

    Urera aurantiaca Wedd. (Urticaceae) is a medicinal plant commonly used in traditional medicine to relieve pain in inflammatory processes. In the present study, the in vivo anti-inflammatory and antinociceptive effects of U. aurantiaca methanolic extract and its possible mechanisms of action were investigated. The extract showed anti-inflammatory activity in the ear edema in mice test (34.3% inhibition), myeloperoxidase (MPO) activity was markedly reduced in animals administered with the extract: within 49.6% and 68.5%. In the histological analysis, intense dermal edema and intense cellular infiltration of inflammatory cells were markedly reduced in the ear tissue of the animals treated with the extract. In the carrageenan-induced hind paw edema in rats assay the extract provoked a significant inhibition of the inflammation (45.5%, 5 h after the treatment) and the MPO activity was markedly reduced (maximum inhibition 71.7%), The extract also exhibited significant and dose-dependent inhibitory effect on the increased vascular permeability induced by acetic acid. The extract presented antioxidant activity in both 2,2-diphenyl-1-picrylhydrazyl and 2,2'-azinobis 3-ethylbenzothiazoline 6-sulfonic acid tests and its total phenol content was 35.4 ± 0.06 mg GAE/g of extract. Also, the extract produced significant inhibition on nociception induced by acetic acid (ED50 : 8.7 mg/kg, i.p.) administered intraperitoneally and orally. Naloxone significantly prevented this activity.

    Cordyceps militaris (bei-chong-chaw, northern worm grass) is a precious and edible entomopathogenic fungus, which is widely used in traditional Chinese medicine (TCM) as a general booster for the nervous system, metabolism, and immunity. Saccharides, nucleosides, mannitol, and sterols were isolated from this fungus. The biological activity of C. militaris was attributed to the saccharide and nucleoside contents. In this study, the aqueous methanolic fraction of C. militaris fruiting bodies exhibited a significant anti-inflammatory activity. Bioactivity-guided fractionation of the active fraction led to the isolation of eight compounds, including one new and two known cerebrosides (ceramide derivatives), two nucleosides, and three sterols. Cordycerebroside A (1), the new cerebroside, along with soyacerebroside I (2) and glucocerebroside (3) inhibited the accumulation of pro-inflammatory iNOS protein and reduced the expression of COX-2 protein in LPS-stimulated RAW264.7 macrophages. This is the first study on the isolation of cerebrosides with anti-inflammatory activity from this TCM.

  1. A Novel Anti-Inflammatory Effect for High Density Lipoprotein.

    Directory of Open Access Journals (Sweden)

    Scott J Cameron

    Full Text Available High density lipoprotein has anti-inflammatory effects in addition to mediating reverse cholesterol transport. While many of the chronic anti-inflammatory effects of high density lipoprotein (HDL are attributed to changes in cell adhesion molecules, little is known about acute signal transduction events elicited by HDL in endothelial cells. We now show that high density lipoprotein decreases endothelial cell exocytosis, the first step in leukocyte trafficking. ApoA-I, a major apolipoprotein of HDL, mediates inhibition of endothelial cell exocytosis by interacting with endothelial scavenger receptor-BI which triggers an intracellular protective signaling cascade involving protein kinase C (PKC. Other apolipoproteins within the HDL particle have only modest effects upon endothelial exocytosis. Using a human primary culture of endothelial cells and murine apo-AI knockout mice, we show that apo-AI prevents endothelial cell exocytosis which limits leukocyte recruitment. These data suggest that high density lipoprotein may inhibit diseases associated with vascular inflammation in part by blocking endothelial exocytosis.

    Cannabidiol (CBD) is a component of cannabis, which does not cause the typical marijuana-type effects, but has a high potential for use in several therapeutic areas. In contrast to Δ(9)-tetrahydrocannabinol (Δ(9)-THC), it binds very weakly to the CB1 and CB2 cannabinoid receptors. It has potent activity in both in vitro and in vivo anti-inflammatory assays. Thus, it lowers the formation of tumor necrosis factor (TNF)-α, a proinflammatory cytokine, and was found to be an oral antiarthritic therapeutic in murine collagen-induced arthritis in vivo. However, in acidic media, it can cyclize to the psychoactive Δ(9)-THC. We report the synthesis of a novel CBD derivative, HU-444, which cannot be converted by acid cyclization into a Δ(9)-THC-like compound. In vitro HU-444 had anti-inflammatory activity (decrease of reactive oxygen intermediates and inhibition of TNF-α production by macrophages); in vivo it led to suppression of production of TNF-α and amelioration of liver damage as well as lowering of mouse collagen-induced arthritis. HU-444 did not cause Δ(9)-THC-like effects in mice. We believe that HU-444 represents a potential novel drug for rheumatoid arthritis and other inflammatory diseases.

    2016-01-01

    Schizophrenia is a major mental illness with a lifetime prevalence of about 1%. Antipsychotic drugs, with a primary mechanism of action that involves dopamine receptor blockade, are the mainstay in the treatment of the disorder. However, despite optimum antipsychotic treatment, few patients return to pre-morbid levels; the treatment deficit includes refractory positive symptoms, negative symptoms, mood impairments, cognitive impairments, social impairments, and/or a variety of medication-related adverse effects, including extrapyramidal symptoms, metabolic disturbances, hyperprolactinemia, and others. To address these, antipsychotic treatment has been augmented with psychosocial interventions, cognitive rehabilitation, different kinds of electrical and magnetic brain stimulation, and a large range of drugs from the neuropsychiatric as well as, surprise, the general medical pharmacopeia. The pleomorphic pathophysiology of schizophrenia includes abnormalities in immunological and inflammatory pathways, and so it is not surprising that anti-inflammatory drugs have also been trialed as augmentation agents in schizophrenia. This article critically examines the outcomes after augmentation with conventional anti-inflammatory interventions; results from randomized controlled trials do not encourage the use of either aspirin (1000 mg/day) or celecoxib (400 mg/day), both of which have been studied for this indication during the past decade and a half.

In this study, eleven oleanolic triterpenes, one of which was novel, were isolated from Chinese acorns (Quercus serrata var. brevipetiolata. The chemical structure of the novel triterpene, which was identified as 2α,3β,19α-trihydroxy-24-oxo-olean-12-en-28-oic acid (1, was established based on the interpretation of chemical and spectroscopic analyses, including IR, HR-ESI-MS, and NMR experiments (1H, 13C NMR, DEPT, 1H-1H COSY, HSQC, HMBC, and NOESY. All isolated compounds were tested for their inhibitory effects on LPS-induced nitric oxide (NO production in RAW 264.7 macrophages. Compared with the positive control drug indomethacin (IC50 = 47.4 μM, compounds 1, 3, 6 and 8 exhibited remarkable anti-inflammatory activities with IC50 values of 5.4, 7.8, 4.0 and 8.9 μM, respectively. Besides, compounds 2, 4, 7 and 9 also showed moderate anti-inflammatory activities with IC50 values of 10.1, 13.0, 20.1 and 17.2 μM, respectively. Furthermore, Compound 1 could inhibit TNF-α-induced IL-6 and IL-8 production in MH7A cells.

    The antioxidant properties of twenty medical herbs used in the traditional Mediterranean and Chinese medicine were studied. Extracts from Forsythia suspensa, Helichrysum italicum, Scrophularia auriculata, Inula viscosa, Coptis chinensis, Poria cocos and Scutellaria baicalensis had previously shown anti-inflammatory activity in different experimental models. Using free radical-generating systems H. italicum. I. viscosa and F. suspensa protected against enzymatic and non-enzymatic lipid peroxidation in model membranes and also showed scavenging property on the superoxide radical. All extracts were assayed at a concentration of 100 microg/ml. Most of the extracts were weak scavengers of the hydroxyl radical and C. chinensis and P. cocos exhibited the highest scavenging activity. Although S. baicalensis inhibited the lipid peroxidation in rat liver microsomes and red blood cells, the extract showed inhibitory actions on aminopyrine N-demethylase and xanthine oxidase activities as well as an pro-oxidant effect observed in the Fe3+-EDTA-H2O2 system. The results of the present work suggest that the anti-inflammatory activities of the same extracts could be explained, at least in part, by their antioxidant properties.

    In this study, we investigated few dietary cucurbits for anticancer activity by monitoring cytotoxic (MTT and LDH assays), apoptotic (caspase-3 and annexin-V assays), and also their anti-inflammatory effects by IL-8 cytokine assay. Aqua-alcoholic (50:50) whole extracts of cucurbits [Lagenaria siceraria (Ls), Luffa cylindrica (Lc) and Cucurbita pepo (Cp)] were evaluated in colon cancer cells (HT-29 and HCT-15) and were compared with isolated biomolecule, cucurbitacin-B (Cbit-B). MTT and LDH assays revealed that the cucurbit extracts and Cbit-B, in a concentration dependent manner, decreased the viability of HT-29 and HCT-15 cells substantially. The viability of lymphocytes was, however, only marginally decreased, yielding a potential advantage over the tumor cells. Caspase-3 assay revealed maximum apoptosis with Ls while annexin V assay demonstrated maximum efficacy of Lc in this context. These cucurbits have also shown decreased secretion of IL-8, thereby revealing their anti-inflammatory capability. The results have demonstrated the therapeutic potential of dietary cucurbits in inhibiting cancer and inflammatory cytokine.

    Full Text Available Caesalpinia ferrea Mart. belongs to the family Fabaceae. Known as pau-ferro and jucá, it is used in folk medicine to treat diabetes, as antipyretic and antirheumatic. This study aimed to evaluate the anti-inflammatory and antinociceptive activities of the ethanol extract of the fruits of C. ferrea (EECf. In the evaluation of anti-inflammatory activity, EECf (50 mg/kg produced significantly inhibition of ear edema by 66.6% compared to control. Indomethacin (10 mg/kg showed inhibition of 83.9% compared to control. EECf (50 mg/kg inhibited of vascular permeability induced by acetic acid and was also able to reduce of cell migration to the peritoneal cavity induced by thioglycolate. In the writhing test induced by acid acetic, EECf (12.5, 25 and 50 mg/kg significantly reduced the number of contortions by 24.9, 46.9 and 74.2%, respectively. In the formalin test, EECf presented effects only in the second phase. The results provided experimental evidence for the effectiveness of the traditional use of C. ferrea in treating various diseases associated with inflammation and pain.

    The objective of this study was to prepare a new biodegradable Mg-based biomaterial, which provides good mechanical integrity in combination with anti-inflammatory function during the degradation process. The silver element was used, because it improved the mechanical properties as an effective grain refiner and it is also treated as a potential anti-inflammatory core. The new degradable Mg-Zn-Ag biomaterial was prepared by zone solidification technology and extrusion. The mechanical properties were mostly enhanced by fine grain strengthening. In addition, the alloys exhibited good cytocompatibility. The anti-inflammatory function of degradation products was identified by both interleukin-1α and nitric oxide modes. The anti-inflammatory impact was significantly associated with the concentration of silver ion. It was demonstrated that Mg-Zn-Ag system was a potential metallic stent with anti-inflammatory function, which can reduce the long-term dependence of anti-inflammatory drug after coronary stent implantation.

    Full Text Available The synthesis of some novel alkyl/aryl substituted tertiary alcohols was accomplished in two steps. The synthetic route involves preparation of Grignard reagents by treating alkyl/aryl bromides with magnesium turnings in dry ether. Then substituted chalcones were reacted with the Grignard reagents to afford alkyl/aryl substituted tertiary alcohols 1-10. The structures of the synthesized compounds were assigned on the basis of FT-IR, 1H-NMR, 13C-NMR and mass spectroscopic data. The in vivo anti-inflammatory activity of the synthesized compounds was evaluated using the carrageenan-induced hind paw edema method and was compared with that of ibuprofen. Some of the newly synthesized compounds showed promising anti-inflammatory activity. The tertiary alcohols 1-10 were also screened for antibacterial activity against ten bacterial strains using seven Gram-positive and three Gram-negative bacteria and for antifungal activity against Aspergillus Flavus, Aspergillus Niger and Aspergillus pterus. Tertiary alcohols 1-10 were found to exhibit good to excellent antimicrobial activities compared to levofloxacin and fluconazole used as standard drugs.

    2009-02-01

    In this second article we describe the more interesting pharmacological interactions in dental practice based on the prescription of analgesic narcotics, paracetamol and non-selective non-steroid anti-inflammatory drugs (NSAI) (which inhibit cyclooxigenase 1 -COX 1- and cyclooxigenase 2 -COX 2-) and selective NSAIs (COX 2 inhibitors). The importance of preventing the appearance of these pharmacological interactions is because these are medicaments prescribed daily in odontology for moderate pain treatment and inflammation in the oral cavity. Paracetamol can interact with warfarin and therefore care should be taken with chronic alcoholic patients. All NSAIs reduce renal blood flow and consequently are capable of reducing the efficacy of medicaments used for treating arterial hypertension, which act via a renal mechanism. Especial attention should be taken considering the risk of interaction between the antagonists of AT1 receptors of angiostensin II (ARAII) and the NSAIs.

    Full Text Available Non-steroidal anti-inflammatory drugs (NSAIDs inhibit the isoenzymes COX-1 and COX-2 of cyclooxygenase (COX. Renal side effects (e.g., kidney function, fluid and urinary electrolyte excretion vary with the extent of COX-2-COX-1 selectivity and the administered dose of these compounds. While young healthy subjects will rarely experience adverse renal effects with the use of NSAIDs, elderly patients and those with co-morbibity (e.g., congestive heart failure, liver cirrhosis or chronic kidney disease and drug combinations (e.g., renin-angiotensin blockers, diuretics plus NSAIDs may develop acute renal failure. This review summarizes our present knowledge how traditional NSAIDs and selective COX-2 inhibitors may affect the kidney under various experimental and clinical conditions, and how these drugs may influence renal inflammation, water transport, sodium and potassium balance and how renal dysfunction or hypertension may result.

    2014-06-01

    Non-steroidal anti-inflammatory drugs (NSAIDs) are frequently used to alleviate pain of the patients who suffer from inflammatory conditions like rheumatoid arthritis, osteoarthritis, and other painful conditions like gout. This class of drugs works by blocking cyclooxgenases which in turn block the prostaglandin production in the body. Most often, NSAIDs and antihypertensive drugs are used at the same time, and their use increases with increasing age. Moreover, hypertension and arthritis are common in the elderly patients requiring pharmacological managements. An ample amount of studies put forth evidence that NSAIDs reduce the efficiency of antihypertensive drugs plus aggravate pre-existing hypertension or make the individuals prone to develop high blood pressure through renal dysfunction. This review will help doctors to consider the effects and risk factors of concomitant prescription of NSAIDs and hypertensive drugs.

  15. The Anti-inflammatory mechanisms of Hsp70

    Directory of Open Access Journals (Sweden)

    Thiago J Borges

    2012-05-01

    Full Text Available Immune responses to heat shock proteins (Hsp develop in virtually all inflammatory diseases; however, the significance of such responses is only now becoming clear. In experimental disease models, Hsp administration can prevent or arrest inflammatory damage, and in initial clinical trials in patients with chronic inflammatory diseases, Hsp peptides have been shown to promote the production of anti-inflammatory cytokines, indicating immunoregulatory potential of Hsp. Therefore, the presence of immune responses to Hsp in inflammatory diseases can be seen as an attempt of the immune system to correct the inflammatory condition. Hsp70 can modulate inflammatory responses in models of arthritis, colitis and graft rejection, and the mechanisms underlying this effect are now being elucidated. Incubation with microbial Hsp70 was seen to induce tolerogenic DCs and to promote a suppressive phenotype in myeloid-derived suppressor cells and monocytes. These DC could induce regulatory T cells (Tregs, independently of the antigens they presented. Some Hsp70 family members are associated with autophagy, leading to a preferential uploading of Hsp70 peptides in MHC class II molecules of stressed cells. Henceforth, conserved Hsp70 peptides may be presented in these situations and constitute targets of Tregs, contributing to downregulation of inflammation. Finally, an interfering effect in multiple intracellular inflammatory signaling pathways is also known for Hsp70. Altogether it seems attractive to use Hsp70, or its derivative peptides, for modulation of inflammation. This is a physiological immunotherapy approach, without the immediate necessity of defining disease specific auto-antigens. In this article, we present the evidence on anti-inflammatory effects of Hsp70 and discuss the need for experiments that will be crucial for the further exploration of the immuno-suppressive potential of this protein.

    Croton celtidifolius Baill commonly known as "sangue-de-adave" is a tree found in the Atlantic Forest of south of Brazil, mainly in Santa Catarina. The bark and leaf infusions of this medicinal plant have been popularly used for the treatment of inflammatory diseases. In this study we evaluated the anti-inflammatory and antioxidant properties of crude extract (CE), aqueous fraction (AqF), ethyl acetate fraction (EAF), butanolic fraction (BuF) and catechin, gallocatechin and sub-fractions, 19SF, 35SF and 63SF that contained a mixture of proanthocyanidins and were derived from the EAF fraction. The CE, AqF, EAF, BuF, catechin and sub-fractions 35SF and 63SF reduced paw edema induced by carrageenan. The CE, fractions, sub-fractions and isolated compounds showed antioxidant properties in vitro, all were able to scavenge superoxide anions at a concentration of 100 microg ml(-1). The EAF, catechin and gallocatechin were most effective in the deoxyribose assay, IC50 0.69 (0.44-1.06), 0.20 (0.11-0.39), 0.55 (0.28-1.08) microg x ml(-1) respectively. The CE and other fractions and sub-fractions inhibited deoxyribose degradation up to 1 microg x ml(-1). In the hydrophobic system only AqF did not show lipid peroxidation inhibition. The CE, other fractions, sub-fractions and isolated compounds inhibited lipidid peroxidation only at a concentration of 100 microg x ml(-1). In summary, this study demonstrates that Croton celtidifolius bark has significant anti-inflammatory and antioxidant activity.

    Dairy product consumption is often associated with negative effects because of its naturally high levels of saturated fatty acids. However, recent research has shown that dairy lipids possess putative bioactivity against chronic inflammation. Inflammation triggers the onset of several chronic diseases, including cardiovascular disease, type 2 diabetes mellitus, obesity, and cancer. This review discusses the anti-inflammatory properties of dairy lipids found in milk, yogurt, and cheese, and it examines them in relation to their implications for human health: their protective effects and their role in pathology. We also consider the effect of lipid profile alteration in dairy products-by using ruminant dietary strategies to enrich the milk, or by lipid fortification in the products. We critically review the in vivo, in vitro, ex vivo, and epidemiological studies associated with these dairy lipids and their role in various inflammatory conditions. Finally, we discuss some suggestions for future research in the study of bioactive lipids and dairy products, with reference to the novel field of metabolomics and epidemiological studies.

    The use of analgesia has become standard, and appropriate, practice in avian medicine. As in mammals, pain control in avian patients is usually accomplished with opioids and nonsteroidal anti-inflammatory drugs (NSAIDs) used singly or in combination for a multimodal approach. Despite their usefulness, widespread use, and relative safety in clinical use, few controlled studies in birds have been conducted on efficacy, safety, and dosing. The guidelines for the use of NSAIDs in raptors and other birds have mainly been empirical. More recently, NSAIDs in free-living raptors have emerged as a major conservation issue with the discovery that diclofenac sodium was responsible for the population crash of three species of Gyps vultures in southern Asia. In this context, residues of veterinary NSAIDs in domestic animals are now considered environmental contaminants that can be significantly toxic to vultures and possibly other avian scavengers. Ironically, the disaster with Asian vultures has led to a considerable body of research on NSAIDs in raptors to the benefit of clinicians who now have scientific information available to help assess dosing, safety, toxicity, and pharmacokinetics of NSAIDs in their raptor patients.

  7. Anti-Inflammatory Dimethylfumarate: A Potential New Therapy for Asthma?

    Directory of Open Access Journals (Sweden)

    Petra Seidel

    2013-01-01

    Full Text Available Asthma is a chronic inflammatory disease of the airways, which results from the deregulated interaction of inflammatory cells and tissue forming cells. Beside the derangement of the epithelial cell layer, the most prominent tissue pathology of the asthmatic lung is the hypertrophy and hyperplasia of the airway smooth muscle cell (ASMC bundles, which actively contributes to airway inflammation and remodeling. ASMCs of asthma patients secrete proinflammatory chemokines CXCL10, CCL11, and RANTES which attract immune cells into the airways and may thereby initiate inflammation. None of the available asthma drugs cures the disease—only symptoms are controlled. Dimethylfumarate (DMF is used as an anti-inflammatory drug in psoriasis and showed promising results in phase III clinical studies in multiple sclerosis patients. In regard to asthma therapy, DMF has been anecdotally reported to reduce asthma symptoms in patients with psoriasis and asthma. Here we discuss the potential use of DMF as a novel therapy in asthma on the basis of in vitro studies of its inhibitory effect on ASMC proliferation and cytokine secretion in ASMCs.

    Palm oil is one of the most important edible oils in the world. Its composition (rich in palmitate and oleate) make it suitable for general food uses but its utility could be increased if its fatty acid quality could be varied. In this study, we have modified a palm olein fraction by transesterification with the n-3 polyunsaturated fatty acids, alpha-linolenate or eicosapentaenoic acid (EPA). Evaluation of the potential nutritional efficacy of the oils was made using chondrocyte culture systems which can be used to mimic many of the degenerative and inflammatory pathways involved in arthritis. On stimulation of such cultures with interleukin-1alpha, they showed increased expression of cyclooxygenase-2, the inflammatory cytokines tumour necrosis factor-alpha (TNF-alpha), IL-1alpha and IL-1beta and the proteinase ADAMTS-4. This increased expression was not affected by challenge of the cultures with palm olein alone but showed concentration-dependent reduction by the modified oil in a manner similar to EPA. These results show clearly that it is possible to modify palm oil conveniently to produce a nutraceutical with effective anti-inflammatory properties.

    Osteoarthritis (OA) is a major disability of elderly people. Sesamin is the main compound in Sesamun indicum Linn., and it has an anti-inflammatory effect by specifically inhibiting Δ5-desaturase in polyunsaturated fatty acid biosynthesis. The chondroprotective effects of sesamin were thus studied in a porcine cartilage explant induced with interleukin-1beta (IL-1β) and in a papain-induced osteoarthritis rat model. With the porcine cartilage explant, IL-1β induced release of sulfated-glycosaminoglycan (s-GAG) and hydroxyproline release, and this induction was significantly inhibited by sesamin. This ability to inhibit these processes might be due to its ability to decrease expression of MMP-1, -3 and -13, which can degrade both PGs and type II collagen, both at the mRNA and protein levels. Interestingly, activation of MMP-3 might also be inhibited by sesamin. Moreover, in human articular chondrocytes (HACs), some pathways of IL-1β signal transduction were inhibited by sesamin: p38 and JNK. In the papain-induced OA rat model, sesamin treatment reversed the following pathological changes in OA cartilage: reduced disorganization of chondrocytes in cartilage, increased cartilage thickness, and decreased type II collagen and PGs loss. Sesamin alone might increase formation of type II collagen and PGs in the cartilage tissue of control rats. These results demonstrate that sesamin efficiently suppressed the pathological processes in an OA model. Thus, sesamin could be a potential therapeutic strategy for treatment of OA.

    The unique properties of macroporous, mesoporous, and microporous systems, including their ability to accommodate molecules of different sizes inside their pores and to act as drug delivery systems, have been the object of extensive studies. In this work, mesoporous silica with hexagonal structure was obtained by template synthesis via the sol-gel process. The resulting material was used as support to accommodate the anti-inflammatory agent indomethacin. The alkaline route was used to prepare the mesoporous silica; cetyltrimethylammonium bromide was employed as porogenic agent. The silica particles were functionalized with 3-aminopropyltriethoxysilane alkoxide (APTES) by the sol-gel post-synthesis method. Indomethacin was incorporated into the silica functionalized with APTES and into non-functionalized silica. The resulting systems were characterized by x-ray diffraction (XRD), specific area, infrared spectroscopy, and thermal analyses (TGA). XRD attested to formation of mesoporous silica with hexagonal structure. This structure remained after silica functionalization with APTES and incorporation of indomethacin. Typical infrared spectroscopy vibrations and organic material decomposition during TGA confirmed silica functionalization and drug incorporation. The specific surface area and pore volume of the functionalized material incorporated with indomethacin decreased as compared with the specific surface area and pore volume of the non-functionalized silica containing no drug, suggesting both the functionalizing agent and the drug were present in the silica. Cytotoxicity tests conducted on normal fibroblasts (GM0479A) cells attested that the silica matrix containing indomethacin was less toxic than the free drug.

    Nonsteroidal anti-inflammatory drugs (NSAIDs) are mainstays of the treatment of osteoarthritis (OA) but have dose- and age-related risks of gastrointestinal, cardiovascular, and renal adverse events (AEs). As a result, US and international guidelines recommend caution when prescribing oral NSAIDs, particularly in older patients and those with significant comorbidities. For OA of the hands and knees, topical NSAIDs provide efficacy similar to oral NSAIDs, with far less systemic distribution. Treatment-related cardiovascular, renal, and other serious AEs with topical NSAIDs have not been reported. At present, only 2 topical NSAIDs are approved in the United States for the treatment of OA: diclofenac sodium 1% gel for hand or knee OA and diclofenac sodium 1.5% in 45.5% dimethylsulfoxide solution for knee OA. Clinical trial data for these products have demonstrated efficacy superior to placebo or similar to oral diclofenac with AE profiles similar to placebo, except for application site reactions. In large double-blind trials, gastrointestinal AEs were infrequent and did not include ulcers, perforations, or bleeding. The purpose of this brief review is to examine the data from controlled double-blind trials evaluating the use of topical NSAIDs in patients with OA. Articles included were identified via a search of PubMed covering the period from January 1, 2005 through March 31, 2010. Reference lists from OA treatment guidelines and meta-analyses were reviewed for additional citations of importance.

    2001-02-01

    The monocyte locomotion inhibitory factor (MLIF), a heat-stable oligopeptide found in the supernatant fluid of Entamoeba histolytica axenic cultures was isolated by ultra-filtration, gel-sieve chromatography and high powered liquid chromatography (HPLC), and its primary structure (Met-Gln-Cys-Asn-Ser) established by Edman sequencing and mass-spectrometry (MS). A synthetic peptide had the same selective anti-inflammatory features as the native material in comparable concentrations: in vitro inhibition of the locomotion in human peripheral blood monocytes, and of the respiratory burst in the same cells and in human neutrophil polymorphonuclear leucocytes; and in vivo depression of delayed hypersensitivity skin reactions to dinitrochlorobenzene in guinea pigs. This oligopeptide is apparently synthesized by the ameba as suggested by [(35)S]-Cys and Met incorporation, probably as part of a larger molecule, from which it is cleaved by proteolysis. The full sequence was not found in the 431 available E. histolytica protein sequences. The factor may contribute to the unexpected paucity of the late inflammatory reaction found in advanced invasive amebiasis and, perhaps in consequence, to the regeneration without scarring (restitutio ad integrum) of the affected organs that is observed following successful treatment of this disease

    The medicinal uses of saffron (Crocus sativus Linnaeus) have a long history beginning in Asian countries since the Late Bronze Age. Recent studies have validated its potential to lower the risk of several diseases. Some metabolites derived from saffron stigmas exert numerous therapeutic effects due to hypolipidemic, antitussive, antioxidant, antidiabetic activities and many others. Water and ethanol extracts of Crocus sativus L. are cardioprotective and counteract neurodegenerative disorders. Many of these medicinal properties of saffron can be attributed to a number of its compounds such as crocetin, crocins and other substances having strong antioxidant and radical scavenger properties against a variety of radical oxygen species and pro-inflammatory cytokines. Botany, worldwide spreading of cultivars, biochemical pathways, active constituents and chemical detection methods are reviewed. Therapeutic uses of saffron principles with particular regard to those exhibiting antioxidant and thus anti-inflammatory features are discussed. To date, very few adverse health effects of saffron have been demonstrated. At high doses (more than 5 g/die day), it should be avoided in pregnancy owing to its uterine stimulation activity.

    Full Text Available Non Steroidal Anti Inflammatory Drugs (NSAID have been associated with a sudden and sustained rise in the incidence of gastrointestinal ulcer complications. The aim of the study was to reveal the endoscopical abnormalities found in the duodenum & proximal jejunum due to NSAID. Thirty eight patients taking NSAID for their arthritis or rheumatism were included in this study. Gastro-duodeno-jejunoscopy was done with Olympus PCF-10. The endoscopical appearances of NSAID entero gastropathy were evaluated with a scoring system. The NSAID-entero-gastropathy appearances were endoscopically seen as hyperemia, erosion and ulcer. From all patient recruited, 7.9% complaint of diarrhea and 71.1% complaint of dyspepsia. Endoscopically, in the duodenal bulb we found 79% cases of hyperemia, 39.5% cases of erosion and 7.9% cases of ulcer. In the second part (descending part of the duodenum we found 28.9% cases of hyperemia, 15.8% cases of erosion and 2.6% case of ulcer. In the jejunum, we found 7.9% cases of hyperemia, 2.6% case of erosion and no ulcer. It is concluded that the most frequent abnormal endoscopical appearances in NSAID- enteropathy was hyperemia. The most frequent site of NSAID-enteropathy abnormal findings was in the duodenal bulb. (Med J Indones 2005; 14: 225-9Keywords: NSAID-enteropathy, endoscopical appearances.

    Full Text Available Moringa oleifera Lam. Is a small or medium-sized tree, about 10m high, found wild in the sub-Himalayan tract. The leaves are rich in vitamin A and C and are considered useful in scurvy and catarrhal affections. The leaves are rich in ascorbic acids, amino acids, sterols, isoquercetin glucoside, carotenes, rhamnetin, kaempferol and kaempferitrin. Flowers are traditionally used as tonic, diuretic and abortifacient considered as anthelmintic and also used to cure inflammation, muscle disease, tumors and enlargement of the spleen. All part of this plant is used for the treatment of ascites, rheumatism. Venomous bites and for enhancing cardiac function. In present study, the anti-inflammatory activity was investigated by employing main model Carrageenan induced paw odema (Winter et al., 1962. The results showed a dose dependent decrease in size of odema when observed at 0hr, 1hr, 2hr, 3hr, and 4hr. This effect corresponded with the maximum effect of test dose at 2 hr (Carrageenan-induced paw. The p value<0.0001 was considered to be statistically significant.

    Full Text Available Context: Strobilanthus callosus Nees and Strobilanthus ixiocephala Benth belongs to family Acanthaceae. The plants have been the subject of scientific research which confirms its use in folk medicine as anti-inflammatory drugs showing potent anti-rheumatic effects. Previous research claims the anti-inflammatory and anti-arthritic activities of Lupeol and 19α-H Lupeol isolated from Strobilanthus callosus and Strobilanthus ixiocephala roots. Based on the literature cited, the unexplored parts stems and leaves of the two species were selected for the present study. Aim: The present study is designed to isolate steroidal and alkaloidal components from the two species Strobilanthus callosus and Strobilanthus ixiocephala using the unexplored parts viz. stems and leaves and to investigate its anti-inflammatory effect. Settings and Design: The anti-inflammatory effect was investigated employing subacute anti-inflammatory models namely cotton pellet granuloma and carrageenan-induced rat paw edema. Materials and Methods: Anti-inflammatory activity was carried out using isolated test components RVS-A (Lupeol, RVS-C (Doctriacantone and standard drug Diclofenac sodium (10 mg/kg. Results: The present study has dealt up with isolation of two phytoconstituents Lupeol and Dotriacontane which gave marked anti-inflammatory activity at the dose 20 mg/kg in both the models Carrageenan induced rat paw edema and Cotton pellet granuloma. Conclusion: The results confirm that the mechanism of the anti-inflammatory effect of RVS-A (Lupeol and RVS-C (Doctriacantone involves reduction of prostaglandins through inhibition of cyclooxygenase and suppression of proliferative phase of sub acute inflammation. Thus the steroidal and alkaloidal components Lupeol and Doctriacantone isolated from Strobilanthus callosus Nees and Strobilanthus ixiocephala Benth shows marked anti-inflammatory activity.

    1978-10-01

    Topical anti-inflammatory activity of steroidal and non-steroidal agents was assessed on inflammation produced by heat. A burn was produced on the ears of rats and the inflammation was quantitated gravimetrically. Steroidal anti-inflammatory agents were ranked in order of decreasing activity: triamcinolone acetonide, dexamethasone, prednisolone and hydrocortisone acetate. The nonsteroidal agents phenylbutazone and indomethacin were also effective in inhibiting the inflammation. Cholesterol, a steroid devoid of anti-inflammatory activity, was inactive in this test. Hydrocortisone acetate, in particular, appears to be less effective in inhibiting this type of inflammation than inflammation produced by croton oil.

    Full Text Available Background: Lichens produce a variety of substances that possesses pharmacological actions. However, rare products are submitted to rigorous scientific tests or have the risk potential or side effects evaluated. The lack of medical and sanitary control, absence of accurate botanical identification or purity certification, founded in diverse natural products, may represent great danger to population health. This work aimed to evaluate toxic effects and anti-inflammatory action in vivo of Teloschistes flavicans (Sw. Norm. (TFN unrefined extracts, as well as determinate its main constituents. Methods: The carrageenan induced paw edema and cotton pellet implant induced granuloma methods were utilized, besides a classic acute toxicity test. TFN acetone extract inhibited carrageenan paw edema on 60, 120, and 180 min (inhibition percentiles of 45.03%, 60.59% and 41.72%. Results: TFN ethereal (inhibition percentiles of 23.95% and 29.01% and chloroform (inhibition percentiles of 28.8% and 22.04% extracts inhibited edema on 120 and 180 min. None of the extract inhibited the granuloma development. None of the extract caused death or other acute toxicity signs. Vicanicine (60.26% in ethereal extract and 51.17% in acetone extract, parietine (9.60% in ethereal extract and 15.38% on second, falacinol (0.78% in ether and 14.95% in acetone and very low concentration of falacinal (0.15% in ethereal extract and 3.32% in acetone extract were detected in the medicine. Conclusions: The tested extracts have antiedematogenic activity, but are not effective on subchronic inflammation. The extracts do not present toxic effects in administered doses.

  7. Inflammatory and anti-inflammatory effects of soybean agglutinin

    Full Text Available Soybean agglutinin (SBA lectin, a protein present in raw soybean meals, can bind to and be extensively endocytosed by intestinal epithelial cells, being nutritionally toxic for most animals. In the present study we show that SBA (5-200 µg/cavity injected into different cavities of rats induced a typical inflammatory response characterized by dose-dependent exudation and neutrophil migration 4 h after injection. This effect was blocked by pretreatment with glucocorticoid (0.5 mg/kg or by co-injection of N-acetyl-galactosamine (100 x [M] lectin, but not of other sugars (100 x [M] lectin, suggesting an inflammatory response related to the lectin activity. Neutrophil accumulation was not dependent on a direct effect of SBA on the macrophage population since the effect was not altered when the number of peritoneal cells was increased or decreased in vivo. On the other hand, SBA showed chemotactic activity for human neutrophils in vitro. A slight increase in mononuclear cells was observed 48 h after ip injection of SBA. Phenotypic analysis of these cells showed an increase in the CD4+/CD8- lymphocyte population that returned to control levels after 15 days, suggesting the development of an immune response. SBA-stimulated macrophages presented an increase in the expression of CD11/CD18 surface molecules and showed some characteristics of activated cells. After intravenous administration, SBA increased the number of circulating neutrophils and inhibited in a dose-dependent manner the neutrophil migration induced by ip injection of carrageenan into peritoneal cavities. The co-injection of N-acetyl-galactosamine or mannose, but not glucose or fucose, inhibited these effects. The data indicate that soybean lectin is able to induce a local inflammatory reaction but has an anti-inflammatory effect when present in circulating blood

  8. The Epidemiology of Nonsteroidal Anti-Inflammatory Drugs

    1999-01-01

    Full Text Available Nonsteroidal anti-inflammatory drug (NSAID use has increased dramatically in the past two decades. A large proportion of the elderly population (more than 65 years of age holds a current or recent NSAID prescription, accounting for approximately 90% of all NSAID prescriptions. Despite studies that advise finding alternatives for NSAIDs for the management of osteoarthritis, physicians often prescribe NSAIDs first for such common musculoskeletal conditions. Despite being identified as risk factors for gastrointestinal complications, the simultaneous use of two NSAIDs and the coadministration of NSAIDs with corticosteroids and with coumadin continue to occur. The point prevalence of NSAID-induced ulcers is 10% to 30%, and 15% to 35% of all peptic ulcer complications are caused by NSAIDs. The increased risk of gastrointestinal complications when NSAIDs are used is 3% to 5%. This risk increases with other identified risk factors (eg, older age, previous gastrointestinal history, comorbid diseases and poor health. Gastrointestinal causes of hospitalization (eg, gastrointestinal hemorrhage and perforation and death have increased in parallel to increased NSAID use. ‘Antiulcer’ agents are prescribed twice as often in NSAID users, and the economic impact (eg, diagnostic tests and hospitalization is that about one-third of the arthritis budget has been dedicated to deal with gastrointestinal side effects of NSAIDs. Misoprostol and omeprazole have been shown to be cytoprotective for the gastroduodenal mucosa when NSAIDs are used, and misoprostol has been shown to reduce the risk of gastroduodenal ulcer complications. Economic evaluations have suggested that these agents are a cost effective means of dealing with such NSAID-associated problems. Although no NSAID is totally safe, a number of studies have demonstrated that NSAIDs may be ranked according to relative gastrointestinal toxicity.

    Full Text Available Abstract Background α-Mangostin (α-MG is a main constituent of the fruit hull of the mangosteen. Previous studies have shown that α-MG has pharmacological activities such as antioxidant, antitumor, anti-inflammatory, antiallergic, antibacterial, antifungal and antiviral effects. This study aims to investigate the anti-inflammatory molecular action of α-MG on gene expression profiles. Methods U937 and EL4 cells were treated with different concentrations of α-MG in the presence of 0.1 ng/mL lipopolysaccharide (LPS for 4 h. The anti-inflammatory effects of α-MG were measured by the levels of tumor necrosis factor (TNF-α and interleukin (IL-4 in cell culture media, which were determined with enzyme-linked immunosorbent assay kits. The gene expression profiles of all samples were analyzed with a whole human genome microarray, Illumina BeadChip WG-6 version 3, containing 48804 probes. The protein levels were determined by Western blotting analyses. Results α-MG decreased the LPS induction of the inflammatory cytokines TNF-α (P = 0.038 and IL-4 (P = 0.04. α-MG decreased the gene expressions in oncostatin M signaling via mitogen-activated protein kinase (MAPK pathways, including extracellular signal-regulated kinases (P = 0.016, c-Jun N-terminal kinase (P = 0.01 , and p38 (P = 0.008. α-MG treatment of U937 cells reduced the phosphorylation of MAPK kinase 3 / MAPK kinase 6 (P = 0.0441, MAPK-activated protein kinase-2 (P = 0.0453, signal transducers and activators of transcription-1 (STAT1 (P = 0.0012, c-Fos (P = 0.04, c-Jun (P = 0.019 and Ets-like molecule 1 (Elk-1 (P = 0.038. Conclusion This study demonstrates that α-MG attenuates LPS-mediated activation of MAPK, STAT1, c-Fos, c-Jun and EIK-1, inhibiting TNF-α and IL-4 production in U937 cells.

    Noscapine, a plant-derived, non-toxic, over-the-counter antitussive alkaloid has tubulin-binding properties. Based upon the structural resemblance of noscapine to colchicine, a tubulin-binding anti-inflammatory drug, noscapine and its semi-synthetic brominated analogs were examined for in vitro anti-inflammatory activity. Brominated noscapine analogs were found to inhibit cytokine and chemokine release from macrophage cell lines but did not affect cell viability. Brominated noscapine analogs demonstrated anti-inflammatory properties in both TLR- and non-TLR induced in vitro innate immune pathway inflammation models, mimicking septic and sterile infection respectively. In addition, electron microscopy and immunoblotting data indicated that these analogs induced robust autophagy in human macrophages. This study is the first report to identify brominated noscapines as innate immune pathway anti-inflammatory molecules.

    The present study was undertaken to characterize the interactions between nonsteroidal anti-inflammatory drugs and the alpha(2)-adrenoceptor agonist clonidine in an acute nociceptive test. The writhing test was selected as a model of acute visceral pain. Isobolograms were constructed to assess the interactions of clonidine and each nonsteroidal anti-inflammatory drugs, when coadministered intraperitoneally and intrathecally (i.t.). The simultaneous intraperitoneal administration of fixed ratios of ED(50) fractions of all nonsteroidal anti-inflammatory drugs (naproxen, piroxicam, paracetamol, dipyrone or metamizol and nimesulide) combined with clonidine resulted in synergistic interactions. The same combinations administered intrathecally were additive. The synergistic interactions between systemic nonsteroidal anti-inflammatory drugs and clonidine may involve supraspinal mechanisms.

    Oil extracts of flowering tops of Hypericum richeri Vill. prepared in three different ways were evaluated for chemical composition, and anti-inflammatory and gastroprotective activities. An HPLC method was developed for determination of two dominant flavonoids, quercetin and I3,II8-biapigenin. The carrageenan-induced rat paw edema test was used for screening the anti-inflammatory activity, while indomethacin-induced rat gastric mucosa damage test was used for evaluation of gastroprotective activity. The oil extract prepared by maceration with 96% ethanol, followed by extraction with sunflower oil by heating on a water bath, exhibited the highest anti-inflammatory (38.4%) and gastroprotective activities (gastric damage score of 0.9). The same oil extract had the highest content of quercetin (49 microg/mL) and I3,II8-biapigenin (60 microg/mL). These results approve the usage of oil extracts of H. richeri as an anti-inflammatory and gastroprotective agent.

    2015-11-01

    The synthesis and antioxidant evaluation by DPPH scavenging of a series of salicylic acid derivatives is described. Gentisic acid and its ester, amide, and amino analogs possess more radical scavenging capacity than salicylic acid and other salicylate derivatives. This property can possibly provide an additional pathway for anti-inflammatory activity through either single electron or hydrogen atom transfer, leading to a new strategy for the design of anti-inflammatory agents.

    Full Text Available Summary. This is a preliminary investigation of the ethyl acetate extract of the leaf of Tacca integrifolia (TIE for the analgesic activity using writhing response in mice, tail flick test in rats and for anti-inflammatory activity using ethyl phenyl propiolate (EPP-induced ear edema, carrageenan- and arachidonic acid-induced hind paw edema, as well as cotton pellet-induced granuloma formation in rats. The results showed that TIE (200 mg/kg, PO significantly inhibited pain caused by acetic acid injection (65.9% but did not exhibit effect in tail flick test in rats. These findings suggest that analgesic mechanism of TIE may act via peripherally pathway. The study of anti-inflammatory effect showed that TIE significantly inhibited ear edema induced by EPP. TIE (200 mg/kg, PO inhibited paw edema induced by carrageenan (55.5% and arachidonic acid (48.6% but had no effect on cotton-induced granuloma formation in rats. In conclusion, the ethyl acetate extract of leaf of T. integrifolia possessed anti-inflammatory activity in acute inflammation and analgesic activity.Industrial relevant. Plants of the genus Tacca have been reported to possess many activities such as analgesic, anti-inflammatory and, antipyretic activities. Many species have been used to treat high blood pressure, burn, gastric ulcer, and hepatitis. The scientific studies supporting the traditional uses of Tacca integrifolia for some of the alleged activities are still lacking. The screening test for analgesic and anti-inflammatory effect of the ethyl acetate extract of the leaf of Tacca integrifolia provides scientific data to confirm the potentials of T. integrifolia as an analgesic and anti-inflammatory medicinal plant. In addition, the outcomes may be useful to develop a new analgesic and anti-inflammatory drug in the future. Key words.

    Full Text Available This study was designed to determine whether the 50% EtOH fraction from AB-8 macroporous resin fractionation of a 70% EtOH extract of P. Alkekengi (50-EFP has antibacterial and/or anti-inflammatory activity both in vivo and in vitro and to investigate the mechanism of 50-EFP anti-inflammatory activity. Additionally, this study sought to define the chemical composition of 50-EFP. Results indicated that 50-EFP showed significant antibacterial activity in vitro and efficacy in vivo. Moreover, 50-EFP significantly reduced nitric oxide (NO, prostaglandin E2 (PGE2, tumor necrosis factor alpha (TNF-α, interleukin 1 (IL-1, and interleukin 6 (IL-6 production in lipopolysaccharide- (LPS- stimulated THP-1 cells. Nitric oxide synthase (iNOS and cyclooxygenase-2 (COX-2 (examined at the protein level in THP-1 cells were suppressed by 50-EFP, which inhibited nuclear translocation of p65. Consistent with this anti-inflammatory activity in vitro, 50-EFP reduced inflammation in both animal models. Finally, seventeen compounds (8 physalins and 9 flavones were isolated as major components of 50-EFP. Our data demonstrate that 50-EFP has antibacterial and anti-inflammatory activities both in vitro and in vivo. The anti-inflammatory effect appears to occur, at least in part, through the inhibition of nuclear translocation of p65. Moreover, physalins and flavones are probably the active components in 50-EFP that exert antibacterial and anti-inflammatory activities.

    2012-02-01

    Full Text Available Many biological properties have been attributed to various types of propolis, including anti-inflammatory, antimicrobial, antioxidant, antitumor, wound healing, and immunomodulatory activities. This article reviewed studies published that investigated the anti-inflammatory activity of propolis of different origins and/or its isolated components, focusing on the mechanisms of action underlying this activity and also addressing some aspects of immunomodulatory effects. The search was performed of the following databases: PubMed, Science Direct, HighWire Press, Scielo, Google Academics, Research Gate and ISI Web of Knowledgement. The anti-inflammatory activity was associated with propolis or compounds such as polyphenols (flavonoids, phenolic acids and their esters, terpenoids, steroids and amino acids. CAPE is the most studied compounds. The main mechanisms underlying the anti-inflammatory activity of propolis included the inhibition of cyclooxygenase and consequent inhibition of prostaglandin biosynthesis, free radical scavenging, inhibition of nitric oxide synthesis, reduction in the concentration of inflammatory cytokines and immunosuppressive activity. Propolis was found to exert an anti-inflammatory activity in vivo and in vitro models of acute and chronic inflammation and others studies, indicating its promising potential as anti-inflammatory agent of natural origin and as a source of chemical compounds for the development of new drugs.

    Background Since the available anti-inflammatory drugs exert an extensive variety of side effects, the search for new anti-inflammatory agents has been a priority of pharmaceutical industries. Aims The aim of the present study was to assess the anti-inflammatory activities of the essential oil of rose geranium (RGEO). Methods The chemical composition of the RGEO was investigated by gas chromatography. The major components were citronellol (29.13%), geraniol (12.62%), and citronellyl formate (8.06%). In the carrageenan-induced paw edema, five different groups were established and RGEO was administered orally in three different doses. Results RGEO (100 mg/kg) was able to significantly reduce the paw edema with a comparable effect to that observed with diclofenac, the positive control. In addition, RGEO showed a potent anti-inflammatory activity by topical treatment in the method of croton oil-induced ear edema. When the dose was 5 or 10 µl of RGEO per ear, the inflammation was reduced by 73 and 88%, respectively. This is the first report to demonstrate a significant anti-inflammatory activity of Algerian RGEO. In addition, histological analysis confirmed that RGEO inhibited the inflammatory responses in the skin. Conclusion Our results indicate that RGEO may have significant potential for the development of novel anti-inflammatory drugs with improved safety profile. PMID:24103319

    The aim of the study was to assess changes in the activity of anti-inflammatory terpenes from Chilean medicinal plants after the formation of derivatives incorporating synthetic anti-inflammatory agents. Ten new hybrid molecules were synthesized combining terpenes (ferruginol (1), imbricatolic acid (2) and oleanolic acid (3)) with ibuprofen (4) or naproxen (5). The topical anti-inflammatory activity of the compounds was assessed in mice by the arachidonic acid (AA) and 12-O-tetradecanoyl phorbol 13-acetate (TPA) induced ear edema assays. Basal cytotoxicity was determined towards human lung fibroblasts, gastric epithelial cells and hepatocytes. At 1.4 µmol/mouse, a strong anti-inflammatory effect in the TPA assay was observed for oleanoyl ibuprofenate 12 (79.9%) and oleanoyl ibuprofenate methyl ester 15 (80.0%). In the AA assay, the best activity was observed for 12 at 3.2 µmol/mouse, with 56.8% reduction of inflammation, in the same range as nimesulide (48.9%). All the terpenyl-synthetic anti-inflammatory hybrids showed better effects in the TPA assay, with best activity for 6, 12 and 15. The cytotoxicity of the compounds 8 and 10 with a free COOH, was higher than that of 2. The derivatives from 3 were less toxic than the triterpene. Several of the new compounds presented better anti-inflammatory effect and lower cytotoxicity than the parent terpenes.

    Full Text Available Inflammation and pain are the most common health problems treated with traditional remedies which mainly comprise medicinal plants. A number of natural products are used in the traditional medical systems in many countries. An alternative medicine for the treatment of various diseases is getting more popular. Many medicinal plants provide relief of symptoms comparable to that of obtained from allopathic medicines. Therefore agents of natural origin with very little side effects are required as substitute chemicals therapeutics. The methanolic leaf extract of Cocculus hirsutus (100& 200mg/kg Linn (Menispermaceae was investigated for its analgesic and anti-inflammatory effects in laboratory animals. The analgesic activity of the methanolic leaf extract of Cocculus hirsutus was investigated by eddy’s hot plate model and acetic acid induced writhing in mice. Anti-inflammatory activity of Cocculus hirsutus was studied by both in-vitro and in vivo models. Human red blood cells membrane stabilization method was adopted for the in-vitro anti-inflammatory activity and for in-vivo, Carrageenan induced paw edema and cotton pellet induced granuloma in rats was employed. In eddy’s hot plate analgesic study, both the doses of Cocculus hirsutus showed significant (p<0.05 and p<0.01 respectively analgesic activity. In acetic acid induced writhing model, the onset of writhing was delayed and duration of writhing was shortened by the methanolic extract of Cocculus hirsutus.In-vitro anti-inflammatory activity of the methanolic leaf extract of Cocculus hirsutus showed significant anti inflammatory activity in a concentration dependent manner. Cocculus hirsutus showed significant anti-inflammatory activity on both carrgeenan as well as cotton pellet induced granuloma models in rats. From the results, it was concluded that the methanolic leaf extract of Cocculus hirsutus possess analgesic and anti-inflammatory.

    Full Text Available Context: There are reports in the literature of species belonging to the genus Tabebuia with pharmacological potential as anti-inflammatory: Tabebuia avellanedae, Tabebuia chrysanta, Tabebuia rosea, Tabebuia ochracea, among others; however, about of the species Tabebuia hypoleuca no studies demonstrating this activity so far. Aims: To determine the anti-inflammatory activity in the acute phase of the methanolic extracts of T. hypoleuca. Methods: Leaves and stems of T. hypoleuca were collected. The anti-inflammatory activity was assessed using the carrageenin-induced paw edema models and the croton oil induced auricular edema in mice. The qualitative identification of secondary metabolites present in the methanolic extracts was performed by a preliminary phytochemical screening. Results: The anti-inflammatory activity assessments showed that methanol extract of the leaves do not have anti-inflammatory activity at doses tested, while the methanol extract of the stems at the dose of 500 mg/kg showed a significant anti-inflammatory activity in the model of carrageenan-induced paw edema. In the model of croton oil induced auricular edema the methanol extract of the stems administered orally and intraperitoneally showed a significant anti-inflammatory activity at all doses tested. The anti-inflammatory activity found could be due to the presence of metabolites such as tannins, phenols and alkaloids. Conclusions: These studies demonstrate the anti-inflammatory activity of the methanol extract of the stems of Tabebuia hypoleuca, and constitute the first report about this species as anti-inflammatory.

    Full Text Available Much research has been carried out with the aim to discover the therapeutic values of chalcone derivatives. Chalcones possess wide range of pharmacological activity such as antibacterial, antimalarial, antiprotozoal, antitubercular, anticancer, and antifungal agents etc. The presence of reactive α,β-unsaturated keto group in chalcones is found to be responsible for their biological activity. The rapid developments of resistance to antifungal agents, led to design, and synthesize the new antifungal agents. The derivatives of chalcones were prepared using Claisen-Schmidt condensation scheme with appropriate tetralone and aldehyde derivatives. Ten derivatives were synthesized and were biologically screened for antifungal activity. The newly synthesized derivatives of chalcone showed antifungal activity against fungal species, Microsporum gypseum. The results so obtained were superior or comparable to ketoconazole. It was observed that none of the compounds tested showed positive results for fungi Candida albicans nor against fungi Aspergillus niger. Chalcone derivatives showed inhibitory effect against M. gypseum species of fungus. It was found that among the chalcone derivatives so synthesized, two of them, that is, 4-chloro derivative, and unsubstituted derivative of chalcone showed antifungal activity superior to ketoconazole. Thus, these can be the potential new molecule as antifungal agent.

    Objectives. Salvia fruticosa Mill. (S. fruticosa) is widely used in folk medicine. Accordingly, the present study was designed to evaluate the antioxidant and anti-inflammatory activities of S. fruticosa, and to determine the phenolic constituents of its extracts. Methods. The antioxidant activity was determined using 2,2-diphenylpicrylhydrazyl assay. Total phenolic contents were estimated using Folin-Ciocalteu reagent, and high-performance liquid chromatography was performed to identify phenolic constituents. To evaluate the anti-inflammatory activity, carrageenan-induced mouse paw edema was determined plethysmographically. Key Findings. Different plant extracts demonstrated strong radical scavenging activity, where the ethyl acetate extract had the highest value in the roots and the lowest in the aerial parts. This antioxidant activity was correlated to the total phenolic content of different extracts, where rutin and luteolin were the most abundant constituents. Interestingly, both the roots and aerial parts revealed a significant anti-inflammatory activity comparable to diclofenac. Conclusions. This study is the first to demonstrate pharmacologic evidence of the potential anti-inflammatory activity of S. fruticosa. This activity may partly be due to the radical scavenging effects of its polyphenolic contents. These findings warrant the popular use of the East Mediterranean sage and highlight the potential of its active constituents in the development of new anti-inflammatory drugs.

    Full Text Available Citrus fruits have potential health-promoting properties and their essential oils have long been used in several applications. Due to biological effects described to some citrus species in this study our objectives were to analyze and compare the phytochemical composition and evaluate the anti-inflammatory effect of essential oils (EO obtained from four different Citrus species. Mice were treated with EO obtained from C. limon, C. latifolia, C. aurantifolia or C. limonia (10 to 100 mg/kg, p.o. and their anti-inflammatory effects were evaluated in chemical induced inflammation (formalin-induced licking response and carrageenan-induced inflammation in the subcutaneous air pouch model. A possible antinociceptive effect was evaluated in the hot plate model. Phytochemical analyses indicated the presence of geranial, limonene, γ-terpinene and others. EOs from C. limon, C. aurantifolia and C. limonia exhibited anti-inflammatory effects by reducing cell migration, cytokine production and protein extravasation induced by carrageenan. These effects were also obtained with similar amounts of pure limonene. It was also observed that C. aurantifolia induced myelotoxicity in mice. Anti-inflammatory effect of C. limon and C. limonia is probably due to their large quantities of limonene, while the myelotoxicity observed with C. aurantifolia is most likely due to the high concentration of citral. Our results indicate that these EOs from C. limon, C. aurantifolia and C. limonia have a significant anti-inflammatory effect; however, care should be taken with C. aurantifolia.

    A new series of novel benzimidazole derivatives containing substituted pyrid-2-yl moiety and polyhydroxy sugar conjugated to the N-benzimidazole moiety has been synthesized and evaluated as orally bioavailable anti-inflammatory agents with anti-ulcerogenic activity. The anti-inflammatory and anti-ulcerogenic activities of these compounds were compared to diclofenac and omeprazole, respectively. In carrageenan-induced paw oedema assay, 2-methyl-N-((3,4-dimethoxypyridin-2-yl)methyl)-1H-benzimidazol-5-amine (12d) and 1-(1,2,3,5-tetrahydroxy-α-D-mannofuranose)-5-(((3,4-dimethoxypyridin-2yl)methyl)amino)-2-methyl-1H-benzimidazole (15d) displayed dose-dependent anti-inflammatory activities by decreasing the inflammation by 62% and 72%, respectively which is comparable to that of diclofenac (73%). In contrast to diclofenac, the anti-inflammatory activity of these compounds was not only free from any side effects on the gastric mucosa but also showed significant anti-ulcerogenic activity in rat pyloric ligation and ethanol-induced gastric ulcer models similar to that of omeprazole. Together, these findings suggest that 12d and 15d are potent anti-inflammatory agents with concurrent anti-ulcerogenic activity and support its clinical promise as a component of therapeutic strategies for inflammation, for which the gastric side effects are always a major limitation.

    Physalis peruviana is a native plant from the South American Andes and is widely used in traditional Colombian medicine of as an anti-inflammatory medicinal plant, specifically the leaves, calyces, and small stems in poultice form. Previous studies performed by our group on P. peruviana calyces showed potent anti-inflammatory activity in an enriched fraction obtained from an ether total extract. The objective of the present study was to obtain and elucidate the active compounds from this fraction and evaluate their anti-inflammatory activity in vivo and in vitro. The enriched fraction of P. peruviana was purified by several chromatographic methods to obtain an inseparable mixture of two new sucrose esters named peruviose A (1) and peruviose B (2). Structures of the new compounds were elucidated using spectroscopic methods and chemical transformations. The anti-inflammatory activity of the peruvioses mixture was evaluated using λ-carrageenan-induced paw edema in rats and lipopolysaccharide-activated peritoneal macrophages. Results showed that the peruvioses did not produce side effects on the liver and kidneys and significantly attenuated the inflammation induced by λ-carrageenan in a dosage-dependent manner, probably due to an inhibition of nitric oxide and prostaglandin E2, which was demonstrated in vitro. To our knowledge, this is the first report of the presence of sucrose esters in P. peruviana that showed a potent anti-inflammatory effect. These results suggest the potential of sucrose esters from the Physalis genus as a novel natural alternative to treat inflammatory diseases.

    Full Text Available The effects of Crotalus durissus terrificus venom (Cdt were analyzed with respect to the susceptibility and the inflammatory mediators in an experimental model of severe envenomation. BALB/c female mice injected intraperitoneally presented sensibility to Cdt, with changes in specific signs, blood biochemical and inflammatory mediators. The venom induced reduction of glucose and urea levels and an increment of creatinine levels in serum from mice. Significant differences were observed in the time-course of mediator levels in sera from mice injected with Cdt. The maximum levels of IL-6, NO, IL-5, TNF, IL-4 and IL-10 were observed 15 min, 30 min, 1, 2 and 4 hours post-injection, respectively. No difference was observed for levels of IFN-γ. Taken together, these data indicate that the envenomation by Cdt is regulated both pro- and anti-inflammatory cytokine responses at time-dependent manner. In serum from mice injected with Cdt at the two first hours revealed of pro-inflammatory dominance. However, with an increment of time an increase of anti-inflammatory cytokines was observed and the balance toward to anti-inflammatory dominance. In conclusion, the observation that Cdt affects the production of pro- and anti-inflammatory cytokines provides further evidence for the role played by Cdt in modulating pro/anti-inflammatory cytokine balance.

    Full Text Available Currently used steroidal and non steroidal anti-inflammatory drugs have severe side effects. These side effects are very difficult to manage than the disease itself. Hence, there is to search new safe resources to cure such diseases that the use of plant based drugs. This study deals with anti-inflammatory evaluation of the hydroalcoholic extract of Ipomoea aquatica leaves as well as their possible mechanism of action. A carrageenan‐induced rat paw oedema model was used for anti-inflammatory study. The mechanism/s by which Ipomoea aquatica is mediated the ant-inflammatory activity was determined by its effects in antihistamine activity, prostaglandin synthesis inhibition activity, membrane stabilizing activity and protein denaturation inhibition activity. Dose dependent anti-inflammatory activity was found with HAEIA in rat paw oedema model using carrageenan. HAEIA effective to suppressed the wheal area formed by histamine. HAEIA revealed dose dependent prostaglandin synthesis inhibition activity. HAEIA was effectively inhibited the heat induced hemolysis of HRBCs as well as heat induced albumin denaturation. Therefore, it was concluded that the HAEIA has anti-inflammatory activity possibly mediated through inhibition of release of mediator histamine and prostaglandin and has also HRBCs membrane stabilization and protein denaturation inhibition properties.

    On a preliminary test, anti-inflammatory and analgesic dose-related activities on rats were observed for the aqueous fraction of Urera baccifera; this extract was bioassay-guided fractionated and the final aqueous fraction was used according the ethnobotanical use. Carrageenan-induced edema (n = 6), was used as an assay in the fractionating process. The anti-inflammatory and antinociceptive properties of the final aqueous fraction were studied using in vivo models. For the anti-inflammatory activity rat paw edema (n = 6), pleurisy induced by carrageenan (n = 6) and ear edema induced by topical croton oil (n = 6) models were used, and tail-flick test (n = 6), abdominal constrictions induced by acetic acid (n = 6), and formalin test (n = 6), were used for the antinociceptive activity. The tests performed showed an inhibition effect on leukocyte migration, and a reduction on pleural exudate, as well as dose-dependant peripheral analgesic activity, at a range of 25-100 mg/kg i.p. The final aqueous fraction contains most of the anti-inflammatory activity of the plant U. baccifera. A possible mechanism of action is discussed and based on the results we conclude that this plant has a potential for both anti-inflammatory and analgesic activity at the clinical level.

    Full Text Available Ballota pseudodictamnus (L. Benth. (Lamiaceae, Salvia fruticosa Mill. (Lamiaceae and Thapsia garganica L. (Apiaceae are three well-known medicinal plants from the Libyan flora, which have long been used for the treatment of inflammations. The aim of the present study was to investigate, for the first time, the anti-inflammatory property of the methanol (MeOH extracts of the aerial parts of these plants. Shade-dried and ground aerial parts of B. pseudodictamnus, S. fruticosa and T. garganica were Soxhlet-extracted with MeOH. The extracts were concentrated by evaporation under reduced pressure at 40°C. The anti-inflammatory activity of the extracts was evaluated using the carrageenan-induced mice paw edema model. The administration of the extracts at a dose of 500 mg/kg body weight produced statistically significant inhibition (p < 0.05 of edema within 3 h of carrageenan administration. The results demonstrated significant anti-inflammatory properties of the test extracts. Among the extracts, the S. fruticosa extract exhibited the most significant inhibition of inflammation after 3 h (62.1%. Thus, S. fruticosa could be a potential source for the discovery and development of newer anti-inflammatory ‘leads’ for drug development. The anti-inflammatory activity of B. pseudodictamnus and S. fruticosa could be assumed to be related to high levels of phenolic compounds, e.g., flavonoids, present in these plants.

    2016-06-01

    Full Text Available Macrophages are one kind of innate immune cells, and produce a variety of inflammatory cytokines in response to various stimuli, such as oxidized low density lipoprotein found in the pathogenesis of atherosclerosis. In this study, the effect of phosphatidylserine on anti-inflammatory activity of curcumin-loaded nanostructured lipid carriers was investigated using macrophage cultures. Different amounts of phosphatidylserine were used in the preparation of curcumin nanoparticles, their physicochemical properties and biocompatibilities were then compared. Cellular uptake of the nanoparticles was investigated using a confocal laser scanning microscope and flow cytometry analysis in order to determine the optimal phosphatidylserine concentration. In vitro anti-inflammatory activities were evaluated in macrophages to test whether curcumin and phosphatidylserine have interactive effects on macrophage lipid uptake behavior and anti-inflammatory responses. Here, we showed that macrophage uptake of phosphatidylserine-containing nanostructured lipid carriers increased with increasing amount of phosphatidylserine in the range of 0%–8%, and decreased when the phosphatidylserine molar ratio reached over 12%. curcumin-loaded nanostructured lipid carriers significantly inhibited lipid accumulation and pro-inflammatory factor production in cultured macrophages, and evidently promoted release of anti-inflammatory cytokines, when compared with curcumin or phosphatidylserine alone. These results suggest that the delivery system using PS-based nanoparticles has great potential for efficient delivery of drugs such as curcumin, specifically targeting macrophages and modulation of their anti-inflammatory functions.

    D-002 is a natural mixture of high molecular weight alcohols isolated and purified from beeswax, which contains triacontanol among its main components. This study was undertaken to investigate the anti-inflammatory effects of D-002 administered by the oral route in two animal models commonly used in the pharmacological screening of anti-inflammatory drugs. D-002 administered orally to rats (100 and 200 mg/kg) produced a mild but significant reduction of exudate volume in carrageenan-induced pleuritic inflammation that was accompanied by a marked and significant decrease of leukotriene B4 (LTB4) levels in the exudate. D-002 (25, 50 and 200 mg/kg) also significantly diminished the granuloma weight in the cotton pellet granuloma in rats. In both cases, D-002 was less effective than indomethacin, which was used as an established anti-inflammatory reference drug. On the other hand, D-002 administered from 25-1000 mg/kg did not induce erosions or gastromucosal lesions in rats, which differs from results usually obtained with non steroidal anti-inflammatory drugs. These results indicate that D-002 is a mild anti-inflammatory agent without any ulcerogenic effect associated. The results suggest that these effects are probably not mediated through an inhibition of cyclooxygenase, but a reduction in LTB4 levels induced by D-002 could explain these results.

    Full Text Available The Unani eye drop is an ophthalmic formulation prepared for its beneficial effects in the inflammatory and allergic conditions of the eyes. In the present study, the Unani eye drop formulation was prepared and investigated for its anti-inflammatory and antihistaminic activity, using in vivo and in vitro experimental models respectively. The Unani eye drop formulation exhibited significant anti-inflammatory activity in turpentine liniment-induced ocular inflammation in rabbits. The preparation also showed antihistaminic activity in isolated guinea-pig ileum. The anti-inflammatory and antihistaminic activity of eye drop may be due to presence of active ingredients in the formulation. Although there are many drugs in Unani repository which are mentioned in classical books or used in Unani clinical practice effectively in treatment of eye diseases by various Unani physicians. Inspite of the availability of vast literature, there is a dearth of commercial Unani ocular preparations. So, keeping this in mind, the eye drop formulation was prepared and its anti-inflammatory and antihistaminic activity was carried out in animal models. Thus, in view of the importance of alternative anti-inflammatory and anti- allergic drugs, it becomes imperative to bring these indigenous drugs to the front foot and evaluate their activities.

    Inflammation is a hallmark of many diseases like diabetes, cancers, atherosclerosis and arthritis. Thus, lots of concerns have been raised toward developing novel anti-inflammatory agents. Many alternative herbal medicines possess excellent anti-inflammatory properties, yet their precise mechanisms of action are yet to be elucidated. Here, a novel systems pharmacology approach based on a large number of chemical, biological and pharmacological data was developed and exemplified by a probe herb Folium Eriobotryae, a widely used clinical anti-inflammatory botanic drug. The results show that 11 ingredients of this herb with favorable pharmacokinetic properties are predicted as active compounds for anti-inflammatory treatment. In addition, via systematic network analyses, their targets are identified to be 43 inflammation-associated proteins including especially COX2, ALOX5, PPARG, TNF and RELA that are mainly involved in the mitogen-activated protein kinase (MAPK) signaling pathway, the rheumatoid arthritis pathway and NF-κB signaling pathway. All these demonstrate that the integrated systems pharmacology method provides not only an effective tool to illustrate the anti-inflammatory mechanisms of herbs, but also a new systems-based approach for drug discovery from, but not limited to, herbs, especially when combined with further experimental validations.

    Eugenol is the main constituent of clove oil with anti-inflammatory properties. In this work, for the first time, O/W nanoemulsion of eugenol was designed for the evaluation of anti-inflammatory effects as a topical delivery system. Topical formulations containing 1%, 2% and 4% of eugenol as well as a nanoemulsion system containing 4% eugenol and 0.5% piroxicam were prepared. Further to physicochemical examinations, such as determination of particle size, polydispersity index, zeta potential and physical stability, anti-inflammatory activity was examined in carrageenan-induced paw edema in rats. The optimum formulation was found to contain 2% eugenol (oil phase), 14% Tween 20 (surfactant) and 14% isopropyl alcohol (co-surfactant) in water. Nanoemulsion with polydispersity index of 0.3 and median droplet diameter of 24.4 nm (d50) was obtained. Animal studies revealed that the nanoemulsions exhibited significantly improved anti-inflammatory activity after 1.5 h, compared with marketed piroxicam gel. Additionally, it was shown that increasing the concentration of eugenol did not show higher inhibition of inflammation. Also, the nanoemulsion having piroxicam showed less anti-inflammatory properties compared with the nanoemulsion without piroxicam.

    Citrus fruits have potential health-promoting properties and their essential oils have long been used in several applications. Due to biological effects described to some citrus species in this study our objectives were to analyze and compare the phytochemical composition and evaluate the anti-inflammatory effect of essential oils (EO) obtained from four different Citrus species. Mice were treated with EO obtained from C. limon, C. latifolia, C. aurantifolia or C. limonia (10 to 100 mg/kg, p.o.) and their anti-inflammatory effects were evaluated in chemical induced inflammation (formalin-induced licking response) and carrageenan-induced inflammation in the subcutaneous air pouch model. A possible antinociceptive effect was evaluated in the hot plate model. Phytochemical analyses indicated the presence of geranial, limonene, γ-terpinene and others. EOs from C. limon, C. aurantifolia and C. limonia exhibited anti-inflammatory effects by reducing cell migration, cytokine production and protein extravasation induced by carrageenan. These effects were also obtained with similar amounts of pure limonene. It was also observed that C. aurantifolia induced myelotoxicity in mice. Anti-inflammatory effect of C. limon and C. limonia is probably due to their large quantities of limonene, while the myelotoxicity observed with C. aurantifolia is most likely due to the high concentration of citral. Our results indicate that these EOs from C. limon, C. aurantifolia and C. limonia have a significant anti-inflammatory effect; however, care should be taken with C. aurantifolia.

    Inflammation is a complex biological response that in spite of having available treatments, their side effects limit their usefulness. Because of this, natural products have been the subject of incessant studies, among which the class of terpenes stands out. They have been the source of study for the development of anti-inflammatory drugs, once their chemical diversity is well suited to provide skeleton for future anti-inflammatory drugs. This systematic review reports the studies present in the literature that evaluate the anti-inflammatory activity of terpenes suffering any change in their structures, assessing whether these changes also brought changes in their effects. The search terms anti-inflammatory agents, terpenes, and structure–activity relationship were used to retrieve English language articles in SCOPUS, PUBMED and EMBASE published between January 2002 and August 2013. Twenty-seven papers were found concerning the structural modification of terpenes with the evaluation of antiinflammatory activity. The data reviewed here suggest that modified terpenes are an interesting tool for the development of new anti-inflammatory drugs.

    Full Text Available This study examined the anti-inflammatory potential of Sri Lankan black tea (Camellia sinensis L. Family: Theaceae using both acute (carrageenan-induced paw oedema and chronic (formaldehyde-induced paw oedema and cotton pellet granuloma test rat inflammatory models. Three dose of black tea brew (BTB [84 mg/ml, equivalent to 1.5 cups; 168 mg/ml, equivalent to 3 cups; and 501 mg/ml, equivalent to 9 cups] were made using high grown unblend Dust grade No: 1 black tea samples and was orally administed to rats (n = 6-9/ dose/ test. The results showed that Sri Lankan BTB possesses marked and significant (P < 0.05 oral anti-inflammatory activity against both acute and chronic inflammation. This anti-inflammatory activity was dose-dependent in the carrageenan-induced paw oedema test and cotton pellet granuloma test. Further, in the carrageenan paw oedema model, the anti-inflammatory activity of BTB was almost identical to green tea brew of both Chinese and Japanese types. Further, the BTB had significant antihistamine activity (in terms of wheal test phagocytic cell migration inhibitory activity (in terms carrageenan-induced leucocyte peritoneal infiltration test, nitric oxide production inhibitory activity, antioxidant activity (DPPH method and prostaglandin synthesis inhibition activity (in terms of rat enteropooling test. It is concluded that Sri Lankan black tea has marked anti-inflammatory potential against both acute and chronic inflammation which is mediated via multiple mechanisms.

    Zuidema, Mozow Y.; Korthuis, Ronald J.

    2016-01-01

    Hydrogen sulfide (H2S) is an endogenous gaseous signaling molecule with potent anti-inflammatory properties. Exogenous application of H2S donors, administered either acutely during an inflammatory response or as an antecedent preconditioning intervention that invokes the activation of anti-inflammatory cell survival programs, effectively limits leukocyte rolling, adhesion and emigration, generation of reactive oxygen species, chemokine and cell adhesion molecule expression, endothelial barrier disruption,capillary perfusion deficits, and parenchymal cell dysfunction and injury. This chapter focuses on intravital microscopic methods that can be used to assess the anti-inflammatory effects exerted by H2S, as well as to explore the cellular signaling mechanisms by which this gaseous molecule limits the aforementioned inflammatory responses. Recent advances include use of intravital multiphoton microscopy and optical biosensor technology to explore signaling mechanisms in vivo. PMID:25747477

    Physalis peruviana calyces are used extensively in folk medicine. The crude ethanolic extract and some fractions of calyces were evaluated in order to explore antioxidant and anti-inflammatory activities. The anti-inflammatory activity was evaluated by the TPA-induced ear edema model. The antioxidant in vitro activity was measured by means of the superoxide and nitric oxide scavenging activity of the extracts and fractions. The butanolic fraction was found to be promising due to its anti-inflammatory and antioxidant activities. Therefore, a bio-assay guided approach was employed to isolate and identify rutin (1) and nicotoflorin (2) from their NMR spectroscopic and MS data. The identification of rutin in calyces of P. peruviana supports the possible use of this waste material for phytotherapeutic, nutraceutical and cosmetic preparations.

    Pomegranate (Punica granatum L.) has been used for centuries for the treatment of inflammatory diseases. However, there is a lack of comprehensive information focused on the properties of a certain pomegranate (poly)phenolic profile to cure pain and gastric injury induced by anti-inflammatory drugs. This study investigated the systemic effects of different doses of a HPLC-characterized pomegranate extract on the formalin-induced nociceptive behavior in mice. The effect of the extract against gastric injury caused by non-steroidal anti-inflammatory drugs and ethanol was also assessed. Pomegranate reduced nociception in both phases of the formalin test, suggesting central and peripheral activities to inhibit nociception. Indomethacin-induced gastric injury was not produced in the presence of pomegranate, which also protected against ethanol-induced gastric lesions. The present results reinforce the benefits of pomegranate (poly)phenolics in the treatment of pain as well as their anti-inflammatory properties.

    2016-01-01

    Full Text Available Glucagon-like peptide-1 (GLP-1 is an incretin hormone mainly secreted from intestinal L cells in response to nutrient ingestion. GLP-1 has beneficial effects for glucose homeostasis by stimulating insulin secretion from pancreatic beta-cells, delaying gastric emptying, decreasing plasma glucagon, reducing food intake, and stimulating glucose disposal. Therefore, GLP-1-based therapies such as GLP-1 receptor agonists and inhibitors of dipeptidyl peptidase-4, which is a GLP-1 inactivating enzyme, have been developed for treatment of type 2 diabetes. In addition to glucose-lowering effects, emerging data suggests that GLP-1-based therapies also show anti-inflammatory effects in chronic inflammatory diseases including type 1 and 2 diabetes, atherosclerosis, neurodegenerative disorders, nonalcoholic steatohepatitis, diabetic nephropathy, asthma, and psoriasis. This review outlines the anti-inflammatory actions of GLP-1-based therapies on diseases associated with chronic inflammation in vivo and in vitro, and their molecular mechanisms of anti-inflammatory action.

    David A Scott; Michael Martin

    2006-01-01

    Discoveries in the first few years of the 21st century have led to an understanding of important interactions between the nervous system and the inflammatory response at the molecular level, most notably the acetylcholine (ACh)-triggered, α7-nicotinic acetylcholine receptor (α7nAChR)-dependent nicotinic anti-inflammatory pathway. Studies using the α7nAChR agonist, nicotine, for the treatment of mucosal inflammation have been undertaken but the efficacy of nicotine as a treatment for inflammatory bowel diseases remains debatable. Further understanding of the nicotinic anti-inflammatory pathway and other endogenous anti-inflammatory mechanisms is required in order to develop refined and specific therapeutic strategies for the treatment of a number of inflammatory diseases and conditions, including periodontitis, psoriasis,sarcoidosis, and ulcerative colitis.

    This study investigated some pharmacological properties of virgin coconut oil (VCO), the natural pure oil from coconut [Cocos nucifera Linn (Palmae)] milk, which was prepared without using chemical or high-heat treatment. The anti-inflammatory, analgesic, and antipyretic effects of VCO were assessed. In acute inflammatory models, VCO showed moderate anti-inflammatory effects on ethyl phenylpropiolate-induced ear edema in rats, and carrageenin- and arachidonic acid-induced paw edema. VCO exhibited an inhibitory effect on chronic inflammation by reducing the transudative weight, granuloma formation, and serum alkaline phosphatase activity. VCO also showed a moderate analgesic effect on the acetic acid-induced writhing response as well as an antipyretic effect in yeast-induced hyperthermia. The results obtained suggest anti-inflammatory, analgesic, and antipyretic properties of VCO.

    A sequence of substituted benzophenone-N-ethyl piperidine ether analogues has been synthesized and evaluated as orally active anti-inflammatory agents with reduced side effects. The anti-inflammatory and ulcerogenic activities of the compounds were compared with naproxen, indomethacin, and phenylbutazone. These analogues showed an interesting anti-inflammatory activity in carrageenan-induced foot pad edema assay. In the air-pouch test, some of the analogues reduced the total number of leukocytes of the exudate, which indicates inhibition of prostaglandin production. Side effects of the compounds were examined on gastric mucosa, in the liver and stomach. None of the compounds illustrated significant side effects compared with standard drugs like indomethacin and naproxen.

    Malva parviflora leaves and roots were collected from five sites within the Qacha's Nek District in Lesotho. These plants had two distinct growth forms--upright and prostrate. Hexane, methanol and water extracts were made from the plant material and tested for antibacterial and anti-inflammatory activity using the disc diffusion and cyclooxygenase-1 (Cox-1) bioassays, respectively. Hexane, methanol and water extracts made from Malva parviflora with a prostrate growth form inhibited the growth of Gram-positive and Gram-negative bacteria, while extracts made from plants with an upright growth form inhibited the growth of Gram-positive bacteria only. Cox-1 anti-inflammatory activity of hexane, methanol and water extracts did not show any variation between the two growth forms. The hexane extracts of both the leaves and roots were the most inhibitory. The water extracts had the least inhibitory activity. Bioassay-guided fractionation of the root dichloromethane extract showed that Cox-1 anti-inflammatory activity was caused by at least two compounds that acted synergistically to produce the biological effect.

    Objective: To evaluate anti-inflammatory potential of leaf extract of Skimmia anquetilia by in-vitro and in-vivo anti-inflammatory models. Methods: Acute toxicity study was carried out to determine the toxicity level of different extract using acute toxic class method as described in Organization of Economic Co-operation and Development Guidelines No.423. Carrageenan (1%w/w) was administered and inflammation was induced in rat paw. The leaf extracts of Skimmiaanquetilia were evaluated for anti-inflammatory activity by in-vitro human red blood cell (HRBC) membrane stabilization method and in-vivo carrangeenan-induced rat paw edema method.Results:The in-vitro membrane stabilizing test showed petroleum ether (PE), chloroform (CE), ethyl acetate (EE), methanol (ME) and aqueous extracts (AE) showed 49.44%, 59.39%, 60.15%, 68.40%and 52.18 % protection, respectively as compared to control groups. The in-vivo results of CE, EE and ME showed 58.20%, 60.17% and 67.53% inhibition of inflammation after 6h administration of test drugs in albino rats. The potency of the leaf extracts of Skimmia anquetilia were compared with standard diclofenac (10 mg/kg) which showed 74.18% protection in in-vitro HRBC membrane stabilization test and 71.64% inhibition in in-vivo carrangeenan-induced rat paw edema model. The ME showed a dose dependent significant (P< 0.01) anti-inflammatory activity in human red blood cell membrane stabilization test and reduction of edema in carrageenan induced rat paw edema. Conclusions: The present investigation has confirmed the anti-inflammatory activity ofSkimmia anquetilia due to presence of bioactive phytoconstitutes for the first time and provide the pharmacological evidence in favor of traditional claim of Skimmia anquetilia as an anti-inflammatory agent.

    Polyphenol-rich plant extracts have been shown to possess anti-inflammatory activity against oral pathogen-induced cytokine release in model systems of inflammation. Here, it was hypothesized that a flavanone-rich extract of E. angustifolium exhibits an anti-inflammatory potential against endotoxin-induced inflammatory response in human gingival fibroblasts (HGF-1). HGF-1 cells were stimulated with lipopolysaccharide from Porphyromonas gingivalis (pg-LPS) to release pro-inflammatory cytokines. Concentrations of interleukins IL-6 and IL-8 and macrophage chemoattractant protein-1 in the incubation media upon stimulation were determined by means of magnetic bead analysis. A crude ethanol/water extract of E. angustifolium (EE) was fractionated via gel permeation chromatography into a flavanone-rich fraction (FF) and an erionic acid-rich fraction (EF). Individual flavanones and erionic acids as well as EE, EF and FF were tested in the pg-LPS-stimulated HGF-1 cells for their anti-inflammatory potential. The E. angustifolium extract possessed anti-inflammatory potential in this model system, attenuating the pg-LPS-induced release of IL-6 by up to 52.0 ± 15.5%. Of the individual flavanones, eriodictyol and naringenin had the most pronounced effect. However, a mixture of the flavanones did not possess the same effect as the entire flavanoid fraction, indicating that other compounds may contribute to the anti-inflammatory potential of E. angustifolium. For the first time, an anti-inflammatory potential of E. angustifolium and containing erionic acids has been determined.

    2011-05-01

    Full Text Available Several five membered ring systems, e.g., triazole, oxadiazole dithiazole and thiadiazole with three heteroatoms at symmetrical or asymmetrical positions have been studied because of their interesting pharmacological properties. In this article our emphasis is on synthetic development and pharmacological activity of the triazole moiety which exhibit a broad spectrum of pharmacological activity such as antifungal, antibacterial, anti-inflammatory and anticancer etc. Triazoles have increased our ability to treat many fungal infections, for example, candidiasis, cryptococcal meningitis, aspergillosis etc. However, mortality due to these infections even with antifungal therapy is still unacceptably high. Therefore, the development of new antifungal agents targeting specific fungal structures or functions is being actively pursued. Rapid developments in molecular mycology have led to a concentrated search for more target antifungals. Although we are entering a new era of antifungal therapy in which we will continue to be challenged by systemic fungal diseases, the options for treatment will have greatly expanded.

    Full Text Available Background. In folk medicine, extra virgin olive oil (EVOO is used as a remedy for a variety of diseases. This study investigates the in vivo antinociceptive, anti-inflammatory, and anti-cancer effects of EVOO on mice and rats. Materials and Methods. In this experimental study, using the acetic acid-induced writhing and formalin tests in mice, the analgesic effect of EVOO was evaluated. Acetylsalicylic acid and morphine were used as standard drugs, respectively. The anti-inflammatory activity was investigated by means of the carrageenan-induced paw edema model in rats using acetylsalicylic acid and dexamethasone as standard drugs. Last, the xenograft model in athymic mice was used to evaluate the anticancer effect in vivo. Results. EVOO significantly decreased acetic acid-induced abdominal writhes and reduces acute and inflammatory pain in the two phases of the formalin test. It has also a better effect than Dexamethasone in the anti-inflammatory test. Finally, the intraperitoneal administration of EVOO affects the growth of HCT 116 tumours xenografted in athymic mice. Conclusion. EVOO has a significant analgesic, anti-inflammatory, and anticancer properties.

    For the treatment of inflammatory-based diseases affected by circadian rhythms, the development of once-daily dosage forms is required to target early morning symptoms. In this study, Zn-alginate beads containing ketoprofen (K) were developed by a tandem technique prilling/ionotropic gelation. The effect of main critical variables on particles micromeritics, inner structure as well as on drug loading and in vitro drug release was studied. The in vivo anti-inflammatory efficacy was evaluated using a modified protocol of carrageenan-induced edema in rat paw administering beads to rats by oral gavage at 0, 3, or 5 h before edema induction. Good drug loading and desired particle size and morphology were obtained for the optimized formulation F20. In vitro dissolution studies showed that F20 had a gastroresistant behavior and delayed release of the drug in simulated intestinal fluid. The in vitro delayed release pattern was clearly reflected in the prolonged anti-inflammatory effect in vivo of F20, compared to pure ketoprofen; F20, administered 3 h before edema induction, showed a significant anti-inflammatory activity, reducing maximum paw volume in response to carrageenan injection, whereas no response was observed for ketoprofen. The designed beads appear a promising platform suitable for a delayed release of anti-inflammatory drugs. © 2015 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci 104:3451-3458, 2015.

    2010-02-01

    Full Text Available Background: Anthocephalus cadamba (ReboxMiq. (Rubiaceae is widely distributed throughout the greater part of India, especially at low levels in wet place. Traditionally the bark is used as tonic, febrifuge and to reduce the pain and inflammation. The anti-inflammatory effect of methanol extract obtained from  Anthocephalus cadamba  aerial parts, MEAC, were investigated in this study. Design and methods: The effects of MEAC on the acute and chronic phases of inflammation were studied in carrageenan, dextran and mediators (histamine and serotonin induced paw edema and cotton pallet-induced granuloma, respectively. The anti-edema effect of MEAC was compared with 10 mg/kg of indomethacin orally. Results: The results suggested that MEAC possess potent anti-inflammatory activity. The acute inflammatory model showed that all the doses of MEAC effectively suppressed the edema produced by histamine, so it may be suggested that its anti-inflammatory activity is possibly backed by its antihistaminic activity. In chronic inflammatory model the effect may be due to the cellular migration to injured sites and accumulation of collagen and mucopolysaccharide. Conclusions: On the basis of these findings, it may be inferred that  Anthocephalus cadamba  is an anti-inflammatory agent and the results are in agreement with its traditional use.

    The present study aims at the synthesis of pyrazolines bearing benzothiazole and their evaluation as anti-inflammatory agents. The synthesized compounds were evaluated for their anti-inflammatory potential using carrageenan induced paw edema model. Two compounds 5a and 5d alleviated inflammation more than the standard drug celecoxib. Eight compounds 5 b, 5 c, 5 e, 5 g, 5 h, 6 b, 6 e and 6 f showed anti-inflammatory activity comparable to celecoxib. To understand the mode of action, COX-2 enzyme assay and TNF-α assay were carried out. All the active compounds were assessed for their cytotoxicity. The ulcerogenic risk evaluation was performed on the active compounds that were not found to be cytotoxic. Out of ten active compounds, two compounds (5 d and 6 f) were finally found to be the most potent anti-inflammatory agents attributing to the suppression of the COX-2 enzyme activity and TNF-α production without being either cytotoxic or ulcerogenic.

    Extracts from Lychnophora species are traditionally used in Brazil as anti-inflammatory, and to treat bruise, pain and rheumatism. The ethanolic extract of aerial parts of five species of Lychnophoras and one specie of Lychnophoriopsis were examined for the antinociceptive (hot-plate and writhing tests) and anti-inflammatory (carrageenan-induced paw oedema test) activity in mice, by oral and topical routes, respectively. In the hot-plate test, the Lychnophora pinaster (0.75 g/kg) and Lychnophora ericoides (1.50 g/kg) extracts significantly increased the time for licking of the paws. The species Lychnophora passerina, Lychnophoriopsis candelabrum and Lychnophora pinaster, using the dose of 0.75 g/kg, and Lychnophora ericoides and Lychnophora trichocarpha in both doses evaluated (0.75 and 1.50 g/kg) significantly reduced the number of writhes induced by acetic acid. The administration of Lychnophora pinaster and Lychnophora trichocarpha ointments, in both concentrations evaluated (5 and 10%, w/w), and Lychnophora passerina and Lychnophoriopsis candelabrum, in the concentration of 10%, significantly reduced the paw oedema measured 3 h after carrageenan administration, suggesting, for the first time, an anti-inflammatory activity upon topical administration of these species. The present work comparatively demonstrated the antinociceptive and anti-inflammatory activities of some Brazilian Lychnophoras.

    2014-10-01

    Inspired from occurrence of anti-inflammatory activity of 3-substituted coumarins and antiulcer activity of various 2-substituted benzimidazoles, novel compounds have been designed by coupling coumarin derivatives at 3-position directly or through amide linkage with benzimidazole nucleus at 2-position. The resultant compounds are expected to exhibit both anti-inflammatory and antioxidant activities along with less gastric toxicity profile. Two series of coumarin-benzimidazole derivatives (4a-e and 5a-e) were synthesized and evaluated for anti-inflammatory activity and antioxidant activity. Compounds 4c, 4d and 5a displayed good anti-inflammatory (45.45%, 46.75% and 42.85% inhibition, respectively, versus 54.54% inhibition by indomethacin) and antioxidant (IC50 of 19.7, 13.9 and 1.2 µmol/L, respectively, versus 23.4 µmol/L for butylatedhydroxytoluene) activities. Evaluation of ulcer index and in vivo biochemical estimations for oxidative stress revealed that compounds 4d and 5a remain safe on gastric mucosa and did not induce oxidative stress in tissues. Calculation of various molecular properties suggests the compounds to be sufficiently bioavailable.

There are many natural and synthetic drugs for treatment of inflammation and lot of them are under investigation. Sodium valporate is an antiepileptic drug used particularly in the treatment of primary generalized seizure notably absence, myocolonic seizure, acute manic phase of bipolar disorder and prophylaxis of migraine. The previous observations showed sodium valporate increases level of gamma amino butyric acid (GABA in the central and peripheral nervous system. In acute inflammation, GABA showed a significant attenuation of paw edema and nociception. The aim of this study was evaluation of anti-inflammatory effect of sodium valporate. Materials & Methods: In order to evaluated the anti-inflammatory and antiexudative of sodium valporate doses of 200,400 and 600 mg/kg were investigated on rat paw edema that induced by carrageenan. In addition, the plasma leakage in the inflamed tissue was evaluated by application of trypan blue as intravenous injection. Dexamethason was used as positive control. Results: Results showed sodium valporate doses of 400 and 600 mg/kg decreased inflammatory and exudative effect as compared to control group. Conclusion: Although the anti-inflammatory mechanisms of this drug were not evident but we can say sodium valporate in addition to already proved effects has anti-inflammatory effect.

    Clerodendrum paniculatum L. (Family Verbenaceae) has been used as an antipyretic and anti-inflammatory drug in traditional Thai medicine. This present study investigated the in vitro anti-inflammatory, mutagenic and antimutagenic activities of the ethanolic extract of C. paniculatum (CPE) dried root collected from Sa Kaeo Province of Thailand. Murine macrophage J774A.1 cells were stimulated by lipopolysaccharide (LPS) to evaluate nitric oxide (NO), tumor necrosis factor-α (TNF-α) and prostaglandin E2 (PGE2) production in the anti-inflammatory test while the mutagenic and antimutagenic potential was performed by the Ames test. The outcome of this study displayed that the CPE root significantly inhibited LPS-induced NO, TNF-α, and PGE2 production in macrophage cell line. In addition, the CPE root was not mutagenic toward Salmonella typhimurium strain TA98 and TA100 with and without nitrite treatment. Moreover, it inhibited the mutagenicity of nitrite treated 1-aminopyrene on both strains. The findings suggested the anti-inflammatory and antimutagenic potentials of CPE root.

    2015-01-01

    Colorectal cancer (CRC) is one of the most common human malignancies and a leading cause of cancer-related deaths in developed countries. Identifying effective preventive strategies aimed at inhibiting the development and progression of CRC is critical for reducing the incidence and mortality of this malignancy. The prevention of carcinogenesis by anti-inflammatory agents including nonsteroidal anti-inflammatory drugs (NSAIDs), selective cyclooxygenase-2 (COX-2) inhibitors, and natural products is an area of considerable interest and research. Numerous anti-inflammatory agents have been identified as potential CRC chemopreventive agents but vary in their mechanism of action. This review will discuss the molecular mechanisms being studied for the CRC chemopreventive activity of NSAIDs (i.e., aspirin, sulindac, and ibuprofen), COX-2 inhibitors (i.e., celecoxib), natural products (i.e., curcumin, resveratrol, EGCG, genistein, and baicalein), and metformin. A deeper understanding of how these anti-inflammatory agents inhibit CRC will provide insight into the development of potentially safer and more effective chemopreventive drugs. PMID:26021807

    2007-01-01

    Full Text Available Total RNA from lipopolysaccharide (LPS-stimulated rat macrophages used to treat protoplasts from an Aspergillus nidulans strain originated the RT2 regenerated strain, whose culture supernatant showed anti-inflammatory activity in Wistar rats. The protein fraction presenting such anti-inflammatory activity was purified and biochemically identified. The screening of the fraction responsible for such anti-inflammatory property was performed by evaluating the inhibition of carrageenan-induced paw edema in male Swiss mice. Biochemical analyses of the anti-inflammatory protein used chromatography, carbohydrates quantification of the protein sample, amino acids content analysis and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE. Total sugar quantification revealed 32% glycosylation of the protein fraction. Amino acid analysis of such fraction showed a peculiar pattern presenting 29% valine. SDS-PAGE revealed that the protein sample is pure and its molecular weight is about 40kDa. Intravenous injection of the isolated substance into mice significantly inhibited carrageenan-induced paw edema. The isolated glycoprotein decreased carrageenan-induced paw edema in a prostaglandin-dependent phase, suggesting an inhibitory effect of the isolated glycoprotein on prostaglandin synthesis.

    Full Text Available Several studies have investigated the antinociceptive, immunomodulatory and anti-inflammatory properties of compounds found in the lavender essential oil (LEO, however to date, there is still lack of substantial data. The objective of this study was to assess the antioxidant, anti-inflammatory and antinociceptive effects of lavender essential oil. The 1,1-diphenyl-2-picrylhydrazyl radical decolorization assay was used for antioxidant activity evaluation. The anti-inflammatory activity was tested using two models of acute inflammation: carrageenan-induced pleurisy and croton oil-induced ear edema. The antinociceptive activity was tested using the pain model induced by formalin. LEO has antioxidant activity, which is dose-dependent response. The inflammatory response evoked by carrageenan and by croton oil was reduced through the pre-treatment of animals with LEO. In the pleurisy model, the drug used as positive control, dexamethasone, was more efficacious. However, in the ear swelling, the antiedematogenic effect of the oil was similar to that observed for dexamethasone. In the formalin test, LEO consistently inhibited spontaneous nociception and presented a similar effect to that of tramadol. The results of this study reveal (in vivo the analgesic and anti-inflammatory activities of LEO and demonstrates its important therapeutic potential.

    Inflammation is an immune response against a variety of noxious stimuli, such as infection, chemicals, and physical injury. Eugenol, a natural phenolic extract, has drawn much attention for its various desirable pharmacological functions and is, therefore, broadly used in our daily life and medical practice. However, further usage of eugenol is greatly limited due to its unwanted properties, such as physicochemical instability, poor solubility, and high-dose cytotoxicity. In hopes of extending its applicability through glycosylation, we previously reported a novel, efficient, and high throughput way to biosynthesize α-D-glucosylated eugenol (α-EG). In this study, we further explored the potential superior properties of α-EG to its parent eugenol in terms of anti-inflammatory activities. We demonstrated that α-EG was an effective anti-inflammatory mediator in both non-cellular and cellular environments. In addition, the non-cellular inhibitory effect of α-EG could be amplified by α-glucosidase, which ubiquitously exists in cytoplasm. Furthermore, α-EG exhibited a superior anti-inflammatory effect to its parent eugenol in a cellular environment. In words, our findings collectively suggest that α-EG is a stronger anti-inflammatory mediator and may thereby serve as a desirable substitute for eugenol and a potential therapeutic prodrug in treating inflammatory diseases in the future.

    The ethanolic and aqueous extracts prepared from different parts of Pistacia vera L. (Anacardiaceae) as well as its oleoresin were evaluated for their in vivo anti-inflammatory and antinociceptive activities. Among the extracts screened, only the oleoresin was shown to possess a marked anti-inflammatory activity against carrageenan-induced hind paw edema model in mice without inducing any gastric damage at both 250 and 500 mg/kg doses whereas the rest of the extracts were totally inactive. While the oleoresin was found to display significant antinociceptive activity at 500 mg/kg dose, the ethanolic and aqueous extracts belonging to fruit, leaf, branch and peduncle of Pistacia vera did not exhibit any noticeable antinociception in p-benzoquinone-induced abdominal contractions in mice. Fractionation of the oleoresin indicated the n-hexane fraction to be active, which further led to recognition of some monoterpenes, mainly alpha-pinene (77.5%) by capillary gas chromatography-mass spectrometry (GC-MS) as well as the oleoresin itself. alpha-Pinene was also assessed for its antinociceptive and anti-inflammatory activities in the same manner and exerted a moderate anti-inflammatory effect at 500 mg/kg dose.

    Neuropeptide FF (NPFF) has many functions in regulating various biological processes. However, little attention has been focused on the anti-inflammatory effect of this peptide. In the present study, the in vitro anti-inflammatory activity of NPFF in both primary peritoneal macrophages and RAW 264.7 macrophages was investigated. Our data showed that NPFF suppressed the nitric oxide (NO) production of macrophages in the inflammation process. RF9, a reported antagonist of NPFF receptors, completely blocked the NPFF-induced NO suppression, suggesting a NPFF receptors-mediated pathway is mainly involved. Down-regulation of the nitric oxide synthases significantly inhibited the NPFF-induced NO reduction, indicating the involvement of nitric oxide synthases. However, the nitric oxide synthases were not the only route by which NPFF modulated the NO levels of macrophages. Pharmacological antagonists of the NF-κB signal pathway also completely suppressed the NPFF-induced NO decline. Moreover, we also observed that NPFF is capable of blocking the LPS-induced nuclear translocation of p65 in macrophages, implying the involvement of the NF-κB signal pathway. Finally, we observed that NPFF markedly attenuated the carrageenan-induced mouse paw edema, indicating that NPFF is capable of exerting anti-inflammatory potency in vivo. Collectively, our findings reveal the potential role of NPFF in the anti-inflammatory field both in vitro and in vivo, which will be helpful for the further exploitation of NPFF utility therapeutically.

    Feijoa sellowiana Berg var. coolidge fruit juice was studied in vivo for the anti-inflammatory activity by carrageenin-induced paw edema test and in vitro for the effects on superoxide anion release from neutrophils in human whole blood. The fruit juice was analyzed by the high-performance liquid chromatography method, and quercetin, ellagic acid, catechin, rutin, eriodictyol, gallic acid, pyrocatechol, syringic acid, and eriocitrin were identified. The results showed a significant anti-inflammatory activity of F. sellowiana fruit juice, sustained also by an effective antioxidant activity observed in preliminary studies on 1,1-diphenyl-2-picrylhydrazyl (DPPH) test. In particular, the anti-inflammatory activity edema inhibition is significant since the first hour (44.11%) and persists until the fifth hour (44.12%) of the treatment. The effect on superoxide anion release was studied in human whole blood, in the presence of activators affecting neutrophils by different mechanisms. The juice showed an inhibiting response on neutrophils basal activity in all experimental conditions. In stimulated neutrophils, the higher inhibition of superoxide anion generation was observed at concentration of 10(-4) and 10(-2) mg/mL in whole blood stimulate with phorbol-myristate-13-acetate (PMA; 20% and 40%) and with N-formyl-methionyl-leucyl-phenylalanine (FMLP; 15% and 48%). The significant reduction of edema and the inhibition of O2(-) production, occurring mainly through interaction with protein-kinase C pathway, confirm the anti-inflammatory effect of F. sellowiana fruit juice.

    The methanolic extract of Tephrosia purpurea (Leguminosae) shoots was evaluated in-vitro for its anti-inflammatory and xanthine oxidase inhibitory activity. Anti-inflammatory activity was measured by the Diene-conjugate, HET-CAM and beta-glucuronidase methods. The enzyme inhibitory activity was tested against isolated cow milk xanthine oxidase. The average anti-inflammatory activity of T. purpurea shoot extract in the concentration range of 1-2 microg/mL in the reacting system revealed significant anti-inflammatory activities, which, as recorded by the Diene-conjugate, HET-CAM and beta-glucuronidase assay methods, were 45.4, 10.5, and 70.5%, respectively. Screening of the xanthine oxidase inhibitory activity of the extract in terms of kinetic parameters revealed a mixed type of inhibition, wherein the Km and Vmax values in the presence of 25 to 100 microg/mL shoot extract was 0.20 mM/mL and 0.035, 0.026, 0.023 and 0.020 microg/min, while, for the positive control, the Km and Vmax values were 0.21 mM/mL and 0.043 microg/min, respectively. These findings suggest that T. purpurea shoot extract may possess constituents with good medicinal properties that could be exploited to treat the diseases associated with oxidative stress, xanthine oxidase enzyme activity and inflammation.

    2016-01-01

    Purpose: The aim of this study was to evaluate the antibothropic and anti-inflammatory properties of J. elliptica. Methods: Phytochemical screening and thin-layer chromatography (TLC) assays were performed on J. elliptica hydroalcoholic extract (TE) in order to observe its main constituents. The antibothropic activity of TE was evaluated by the in vitro neuromuscular blockade caused by Bothrops jararacussu venom (Bjssu), in a mouse phrenic nerve-diaphragm model (PND). A quantitative histological study was carried out to observe a possible protection of TE against the venom myotoxicity. The anti-inflammatory activity was also evaluated in two models, Bjssu-induced paw edema, and carrageenan-induced neutrophils migration in the peritoneal cavity. Results: TLC analysis revealed several compounds in TE, such as saponins, alkaloids, and phenolic constituents. TE was able to neutralize the blockade and the myotoxicity induced by venom, when it was pre-incubated for 30 min with venom. In addition, it showed anti-inflammatory activity, inducing less neutrophils migration and reducing paw edema. Conclusion: J. elliptica showed both antibothropic and anti-inflammatory properties.

    Sesquiterpene lactones (SL), secondary plant metabolites from flowerheads of Arnica, exert anti-inflammatory effects mainly by preventing nuclear factor (NF)-kappaB activation because of alkylation of the p65 subunit. Despite its known immunosuppressive action, Arnica has been classified as a plant with strong potency to induce allergic contact dermatitis. Here we examined the dual role of SL as anti-inflammatory compounds and contact allergens in vitro and in vivo. We tested the anti-inflammatory and allergenic potential of SL in the mouse contact hypersensitivity model. We also used dendritic cells to study the activation of NF-kappaB and the secretion of interleukin (IL)-12 in the presence of different doses of SL in vitro. Arnica tinctures and SL potently suppressed NF-kappaB activation and IL-12 production in dendritic cells at high concentrations, but had immunostimulatory effects at low concentrations. Contact hypersensitivity could not be induced in the mouse model, even when Arnica tinctures or SL were applied undiluted to inflamed skin. In contrast, Arnica tinctures suppressed contact hypersensitivity to the strong contact sensitizer trinitrochlorobenzene and activation of dendritic cells. However, contact hypersensitivity to Arnica tincture could be induced in acutely CD4-depleted MHC II knockout mice. These results suggest that induction of contact hypersensitivity by Arnica is prevented by its anti-inflammatory effect and immunosuppression as a result of immune regulation in immunocompetent mice.

    Full Text Available The seeds of Strychnos nux-vomica L., as a traditional Chinese medicine, have good anti-inflammatory and analgesic activities. However, it usually leads to gastrointestinal irritation and systemic toxicity via oral administration. In the study, it was discovered that a novel gel transdermal delivery system contained brucine, the main effective component extracted from Strychnos nux-vomica. Results showed that the brucine gel system inhibited arthritis symptoms and the proliferation of the synoviocytes in the rat adjuvant arthritis model, which indicated its curative effect for rheumatoid arthritis. Meanwhile, it significantly relieved the xylene-induced ear edema in the mouse ear swelling test, which manifested its anti-inflammatory property. Moreover, the brucine gel eased the pain of paw formalin injection in the formalin test, which demonstrated its analgesic effects. In addition, the brucine significantly inhibited lipopolysaccharide (LPS-induced Prostaglandin E2 (PGE2 production without affecting the viability of cell in vitro anti-inflammatory test, which proved that its anti-inflammatory and analgesic actions were related to inhibition of prostaglandin synthesis. It is suggested that the brucine gel is a promising vehicle for transdermal delivery on the treatment of inflammatory disease.

    Full Text Available Aloe emodin is isolated compound of aloe vera which is used traditionally as an anti-inflammatory agent. In vitro pharmacokinetic data suggest that glucuronosyl or sulfated forms of aloe emodin may provide some limitations in its absorption capacity. Aloe emodin was reported to have in vitro anti-inflammatory activity due to inhibition of inducible nitric oxide (iNO and prostaglandin E2, via its action on murine macrophages. However, present work evidenced that molecular docking of aloe emodin modulates the anti-inflammatory activity, as well as expression of COX-2 (cyclooxygenase-2 in rodent. The AEC (4,5-dihydroxy-9,10-dioxo-9,10-dihydroanthracene-2 carboxylic acid was synthesized using aloe emodin as starting material. The study was planned for evaluation of possible anti-inflammatory and antiarthritic activity in carrageenan rat induced paw oedema and complete Freund’s adjuvant induced arthritis in rats. The AE (aloe emodin and AEC significantly P<0.001 reduced carrageenan induced paw edema at 50 and 75 mg/kg. Complete Freund’s adjuvant induced arthritis model showed significant P<0.001 decrease in injected and noninjected paw volume, arthritic score. AE and AEC showed significant effect on various biochemical, antioxidant, and hematological parameters. Diclofenac sodium 10 mg/kg showed significant P<0.001 inhibition in inflammation and arthritis.

    Objective: To evaluate antioxidant, anti-inflammatory, hepatoprotective and vasorelaxant activities of Populus nigra flower buds ethanolic extract. Methods: Antioxidant and anti-inflammatory activities of the extract were assessed using respectively the ABTS test and the animal model of carrageenan-induced paw edema. Protection from hepatic toxicity caused by aluminum was examined by histopathologic analysis of liver sections. Vasorelaxant effect was estimated in endothelium-intact and-rubbed rings of porcine coronary arteries precontracted with high concentration of U46619. Results:The results showed a moderate antioxidant activity (40%), but potent anti-inflammatory activity (49.9%) on carrageenan-induced mice paw edema, and also as revealed by histopathologic examination, complete protection against AlCl3-induced hepatic toxicity. Relaxant effects of the same extract on vascular preparation from porcine aorta precontracted with high concentration of U46619 were considerable at 10-1 g/L, and comparable (P>0.05) between endothelium-intact (67.74%, IC50=0.04 mg/mL) and-rubbed (72.72%, IC50=0.075 mg/mL) aortic rings. Conclusions: The extract exerted significant anti-inflammatory, hepatoprotective and vasorelaxant activities, the latter being endothelium-independent believed to be mediated mainly by the ability of components present in the extract to exert antioxidant properties, probably related to an inhibition of Ca2+influx.

    Antioxidant and anti-inflammatory activities were found from Crocodylus siamensis (C. siamensis) blood. The 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) radical scavenging, nitric oxide scavenging, hydroxyl radical scavenging and linoleic peroxidation assays were used to investigate the antioxidant activities of the crocodile blood. Results show that crocodile blood components had antioxidant activity, especially hemoglobin (40.58 % nitric oxide radical inhibition), crude leukocyte extract (78 % linoleic peroxidation inhibition) and plasma (57.27 % hydroxyl radical inhibition). Additionally, the anti-inflammatory activity of the crocodile blood was studied using murine macrophage (RAW 264.7) as a model. The results show that hemoglobin, crude leukocyte extract and plasma were not toxic to RAW 264.7 cells. Also they showed anti-inflammatory activity by reduced nitric oxide (NO) and interleukin 6 (IL-6) productions from lipopolysaccharide (LPS)-stimulated cells. The NO inhibition percentages of hemoglobin, crude leukocyte extract and plasma were 31.9, 48.24 and 44.27 %, respectively. However, only crude leukocyte extract could inhibit IL-6 production. So, the results of this research directly indicate that hemoglobin, crude leukocyte extract and plasma of C. siamensis blood provide both antioxidant and anti-inflammatory activities, which could be used as a supplementary agent in pharmaceutical products.

    Objective: To investigate the anti-tumor effect and anti-inflammatory activity of Boschniakia rossica (BR). Methods: The expression of tumor marker, GST-P, p53 and p21ras proteins in promotion stage of rat chemical hepatocarcinogenesis were examined by immunohistochemical technique ABC method. Anti-tumor effect of BR was investigated by inhibitory test on Sarcoma180. Anti-inflammatory activity of BR was tested by xylene-induced mouse ear swelling method. Results: BR-H2O extract (the H2O extract fractionated from BR-Methanol extract with CH2Cl2 and H2O) 500 mg/kg has inhibitory effect on the formation of diethylnitrosamine (DEN)-induced glutathione S-transferase placental form (GST-P) positive foci in rat liver with the expression of mutant p53 and p21ras proteins lower than those of non-treated hepatic preneoplastic lesions. BR extract showed inhibitory effect on Sarcoma180 and anti-inflammatory effect in mice by xylene-induced mouse ear swelling tests. Conclusion: BR- H2O extract exerted inhibitory effect on DEN-induced preneoplastic hepatic foci in promotion stage of rat chemical hepatocarcinogenesis and might suppress the growth of solid Sarcoma180 in mice. Both CH2Cl2 and H2O extract from BR exerted anti-inflammatory effect in mice.

    Aloe littoralis Baker (Asphodelaceae family) is a well known plant in southern parts of Iran. Because of its use in Iranian folk medicine as a wound-healing agent, the present study was carried out to investigate anti-inflammatory and wound healing activities of this plant in Wistar rats. A. littoralis raw mucilaginous gel (ALRMG) and also two gel formulations prepared from the raw mucilaginous gel were used in this study. Gel formulations (12.5% and 100% v/w Aloe mucilage in a carbomer base) were applied topically (500 mg once daily) for 24 days in the thermal wound model. Also Aloe gel formulation (100%) and ALRMG (500 mg daily) were evaluated in incisional wound model. Carrageenan-induced paw edema was used to assess the anti-inflammatory effect of intraperitoneal injection of ALRMG. In burn wound, ALRMG and Aloe formulated gel (100%) showed significant (P<0.05) healing effect. Topical application of ALMRG and Aloe formulated gel (100%) promoted healing rate of incisional wound. In carrageenan test, ALRMG (2.5 and 5 ml/Kg) revealed significant (P<0.05) anti-inflammatory activity. Results showed that A. littoralis is a potential wound-healing and anti-inflammatory agent in rats. Further studies are needed to find out the mechanism of these biological effects and also the active constituents responsible for the effects.

    Amauroderma rugosum is a wild mushroom that is worn as a necklace by the indigenous communities in Malaysia to prevent fits and incessant crying by babies. The aim of this study was to investigate the nutritive composition and antioxidant potential and anti-inflammatory effects of A. rugosum extracts on LPS-stimulated RAW264.7 cells. Nutritional analysis of freeze-dried mycelia of A. rugosum (KUM 61131) from submerged culture indicated a predominant presence of carbohydrates, proteins, dietary fibre, phosphorus, potassium, and sodium. The ethanol crude extract (EE), its hexane (HF), ethyl acetate (EAF), and aqueous (AF) fractions of mycelia of A. rugosum grown in submerged culture were evaluated for antioxidant potential and anti-inflammatory effects. EAF exhibited the highest total phenolic content and the strongest antioxidant activity based on 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) assays. HF showed dose-dependent inhibition of NO production in LPS-stimulated RAW264.7 cells and NO radical scavenging activity. Gas chromatographic analysis of HF revealed the presence of ethyl linoleate and ergosterol, compounds with known anti-inflammatory properties. In conclusion, the nutritive compositions and significant antioxidant potential and anti-inflammatory effects of mycelia extracts of A. rugosum have the potential to serve as a therapeutic agent or adjuvant in the management of inflammatory disorders.

    Full Text Available Abstract Cigarette smoke is a major risk factor for a number of diseases including lung cancer and respiratory infections. Paradoxically, it also contains nicotine, an anti-inflammatory alkaloid. There is increasing evidence that smokers have a lower incidence of some inflammatory diseases, including ulcerative colitis, and the protective effect involves the activation of a cholinergic anti-inflammatory pathway that requires the α7 nicotinic acetylcholine receptor (α7nAChR on immune cells. Obesity is characterized by chronic low-grade inflammation, which contributes to insulin resistance. Nicotine significantly improves glucose homeostasis and insulin sensitivity in genetically obese and diet-induced obese mice, which is associated with suppressed adipose tissue inflammation. Inflammation that results in disruption of the epithelial barrier is a hallmark of inflammatory bowel disease, and nicotine is protective in ulcerative colitis. This article summarizes current evidence for the anti-inflammatory effects of nicotine in obesity and ulcerative colitis. Selective agonists for the α7nAChR could represent a promising pharmacological strategy for the treatment of inflammation in obesity and ulcerative colitis. Nevertheless, we should keep in mind that the anti-inflammatory effects of nicotine could be mediated via the expression of several nAChRs on a particular target cell.

    Artemisia anomala S. Moore has been widely used in China to treat inflammatory diseases for hundreds of years. However, mechanisms associated with its anti-inflammatory effect are not clear. In this study, we prepared ethyl acetate, petroleum ether, n-BuOH, and aqueous extracts from ethanol extract of Artemisia anomala S. Moore. Comparing anti-inflammatory effects of these extracts, we found that ethyl acetate extract of this herb (EAFA) exhibited the strongest inhibitory effect on nitric oxide (NO) production in LPS/IFN γ -stimulated RAW264.7 cells. EAFA suppressed the production of NO in a time- and dose-dependent manner without eliciting cytotoxicity to RAW264.7 cells. To understand the molecular mechanism underlying EAFA's anti-inflammatory effect, we showed that EAFA increased total cellular anti-oxidant capacity while reducing the amount of inducible nitric oxide synthase (iNOS) in stimulated RAW264.7 cells. EAFA also suppressed the expression of IL-1 β and IL-6, whereas it elevates the level of heme oxygenase-1. These EAFA-induced events were apparently associated with NF- κ B and MAPK signaling pathways because the DNA binding activity of p50/p65 was impaired and the activities of both ERK and JNK were decreased in EFEA-treated cells comparing to untreated cells. Our findings suggest that EAFA exerts its anti-inflammatory effect by inhibiting the expression of iNOS.

    In this study, 44 compounds in the petroleum ether extract of Maqian (Zanthoxylum myriacanthum var. pubescens) bark, a traditional Dai herbal medicine, were identified by GC-MS. Major components included 3(2H)-benzofuranone, asarinin and (dimethoxymethyl)-3-methoxy-benzene. A total of 18 compounds were isolated from the ethyl acetate extracts of Maqian bark by column chromatography and identified by chemical and spectral analyses. Rhoifoline B, zanthoxyline dimethoxy derivative, N-nortidine, nitidine, decarine are the major alkaloids. Both the petroleum ether and ethyl acetate extracts showed significant inhibition on NO production, which imply anti-inflammatory activity, in lipopolysaccharide-induced RAW 264.7 cells without cell toxicity. Decarine is the major anti-inflammatory constituent with NO IC50 values of 48.43 μM on RAW264.7 cells. The petroleum ether extract, the ethyl acetate extract and decarine showed anti-inflammatory activities through inhibiting TNF-α and IL-1β production in lipopolysaccharide-stimulated THP-1 cells without cell toxicity too. Decarine showed anti-inflammatory activity on human colon cells by reducing IL-6 and IL-8 production in TNF-α+IL-1β-induced Caco-2 cells. These results support the use of Maqian bark as a remedy for enteritis and colitis recorded by Dai medicine in China, and elucidate the major pharmacological compounds in Maqian bark.

    In this study, we evaluated the analgesic effect of methanol extract from Desmodium triflorum DC (MDT) by using animal models of acetic acid-induced writhing response and formalin test. The anti-inflammatory effect of MDT was investigated by lambda-carrageenan-induced paw edema in mice. In order to study the anti-inflammatory mechanism of MDT, we detected the activities of glutathione peroxidase (GPx) and glutathione reductase (GRd) in the liver, the levels of interleukin-1beta (IL-1beta), tumor necrosis factor (TNF-alpha), malondialdehyde (MDA) and nitric oxide (NO) in the edema paw tissue. In the analgesic test, MDT (0.5 and 1.0 g/kg) decreased the acetic acid-induced writhing response and the licking time on the late phase in the formalin test. In the anti-inflammatory test, MDT (0.5 and 1.0 g/kg) decreased the paw edema at the 3rd, 4th, 5th and 6th hour after lambda-carrageenan administration. On the other hand, MDT increased the activities of SOD and GRd in liver tissues and decreased the MDA level in the edema paw at the 3rd hour after lambda-carrageenan-induced inflammation. MDT also affected the levels of interleukin-1beta, tumor necrosis factor-alpha, NO and MDA which were induced by lambda-carrageenan. The results suggested that MDT possessed analgesic and anti-inflammatory effects. The anti-inflammatory mechanism of MDT might be related to the decreases in the level of MDA in the edema paw via increasing the activities of SOD and GRd in the liver, and the NO level via regulating the IL-1beta production and the level of TNF-alpha in the inflamed tissues.

    Full Text Available Objective: 1,3,4-oxadiazole ring is a versatile moiety with a wide range of pharmacological properties. The present work deals with the synthesis and evaluation of the anti-inflammatory activity of two novel 2,5-disubstituted-1,3,4-oxadiazoles (OSD and OPD. Materials and Methods: Carrageenan-induced rat hind paw edema was employed as an acute model of inflammation. For evaluating sub-acute anti-inflammatory activity, carrageenan-induced inflammation in rat air pouch was employed. Complete Freund′s adjuvant-induced arthritis in rats was used as a model of chronic inflammation. To evaluate in vitro anti-inflammatory activity, lipopolysaccharide (LPS-stimulated RAW264.7 cells were used. Results: OSD (100 mg/kg reduced carrageen-induced paw edema by 60%, and OPD (100 mg/kg produced a modest 32.5% reduction. OSD also reduced leukocyte influx and myeloperoxidase in carrageenan-induced rat air pouch model. In complete Freund′s adjuvant-induced arthritis model, both OSD and OPD (200 mg/kg for 14 days reduced paw edema and NO levels. In LPS-stimulated RAW264.7 cells, OSD and OPD inhibited formation of nitric oxide and reactive oxygen species, with OPD showing a better activity in comparison to OSD. Conclusions: OSD was the better of the two compounds in in vivo models of inflammation. The o-phenol substitution at position 2 of oxadiazole ring in OSD may be responsible for its better in vivo anti-inflammatory activity. The ability of the compounds to inhibit LPS-induced pro-inflammatory mediator release suggests an anti-inflammatory mechanism targeting LPS-TLR4-NF-κB signalling pathway, which needs to be explored in detail. The disparate efficacy in vitro and in vivo also requires in-depth evaluation of the pharmacokinetics of these novel oxadiazoles.

    Balance between inflammatory and anti-inflammatory cytokines may be important in malaria presentation and outcome. To clarify cytokine interactions that produce pathology of malaria and control infection, C57BL/6 mice were infected with 10(4) parasitized RBCs from a non-lethal strain of Plasmodium yoelii. Kinetics was monitored showing the course of parasitemia, and cytokines were determined by RT-PCR from liver and spleen tissues. Inflammatory cytokines such as interferon-γ (IFNγ), interleukin (IL)-12, IL-6, tumor necrosis factor-α (TNFα) and anti-inflammatory cytokines, including IL-4 and IL-10, were investigated as key molecules that interact with immune cells in the activation of the immune responses. The production of IFNγ mRNA was found to be higher on day 7 than on day 21 after infection, and IL-12 and IL-6 showed higher expression in the liver than in the spleen. Though TNFα was highly expressed on day 14 after infection and on day 21 in the liver, such expression was decreased on day 21 in the spleen. Anti-inflammatory cytokines showed high expression in both the liver and spleen. The results suggest that a relative balance between inflammatory and anti-inflammatory cytokines is crucial and that the increase of inflammatory cytokine levels during the acute phase of malaria may reflect an early and effective immune response.The counteraction effect of anti-inflammatory cytokines is thought to play a role in limiting progression from uncomplicated malaria to severe life-threatening complications.

    Glucocorticoids (GC) are universally accepted agents for the treatment of anti-inflammatory and immunosuppressive disorders. They are used in the treatment of rheumatic diseases and various inflammatory diseases such as allergy, asthma and sepsis. They bind with GC receptor (GR) and form GC-GR complex with the receptor and exert their actions. On activation the GC-GR complex up-regulates the expression of nucleus anti-inflammatory proteins called as transactivation and down-regulates the expression of cytoplasmic pro-inflammatory proteins called as transrepression. It has been observed that transactivation mechanisms are notorious for side effects and transrepressive mechanisms are identified for beneficial anti-inflammatory effects of GC therapy. GC hampers the function of numerous inflammatory mediators such as cytokines, chemokines, adhesion molecules, arachidonic acid metabolites, release of platelet-activating factor (PAF), inflammatory peptides and enzyme modulation involved in the process of inflammation. The GC resistance is a serious therapeutic problem and limits the therapeutic response of GC in chronic inflammatory patients. It has been observed that the GC resistance can be attributed to cellular microenvironment changes, as a consequence of chronic inflammation. Various other factors responsible for resistance have been identified, including alterations in both GR-dependent and GR-independent signaling pathways of cytokine action, hypoxia, oxidative stress, allergen exposure and serum-derived factors. The present review enumerates various aspects of inflammation such as use of GC for treatment of inflammation and its mechanism of action. Molecular mechanisms of anti-inflammatory action of GC and GC resistance, alternative anti-inflammatory treatments and new strategy for reversing the GC resistance have also been discussed.

    The autonomic nervous system dysfunction with increased sympathetic activity and withdrawal of vagal activity may play an important role in the pathogenesis of viral myocarditis. The vagus nerve can modulate the immune response and control inflammation through a ‘cholinergic anti-inflammatory pathway’ dependent on the α7-nicotinic acetylcholine receptor (α7nAChR). Although the role of β-adrenergic stimulation on viral myocarditis has been investigated in our pervious studies, the direct effect of vagal tone in this setting has not been yet studied. Therefore, in the present study, we investigated the effects of cervical vagotomy in a murine model of viral myocarditis. In a coxsackievirus B3 murine myocarditis model (Balb/c), effects of right cervical vagotomy and nAChR agonist nicotine on echocardiography, myocardial histopathology, viral RNA, and proinflammatory cytokine levels were studied. We found that right cervical vagotomy inhibited the cholinergic anti-inflammatory pathway, aggravated myocardial lesions, up-regulated the expression of TNF-α, IL-1β, and IL-6, and worsened the impaired left ventricular function in murine viral myocarditis, and these changes were reversed by co-treatment with nicotine by activating the cholinergic anti-inflammatory pathway. These results indicate that vagal nerve plays an important role in mediating the anti-inflammatory effect in viral myocarditis, and that cholinergic stimulation with nicotine also plays its peripheral anti-inflammatory role relying on α7nAChR, without requirement for the integrity of vagal nerve in the model. The findings suggest that vagus nerve stimulation mediated inhibition of the inflammatory processes likely provide important benefits in myocarditis treatment. PMID:28197102

    The aerial parts of Lychnophora trichocarpha Spreng. (Asteraceae) are used macerated in water or ethanol to treat inflammation, pain, rheumatism, contusions, bruises and insect bites in Brazilian traditional medicine. In this study, anti-inflammatory activity of ethanol extract from aerial parts of L. trichocarpha and its ethyl acetate fraction was investigated. Sesquiterpene lactones, lychnopholide (Lyc) and eremantholide C (EreC), isolated of ethyl acetate fraction, were also assayed for in vitro and in vivo anti-inflammatory activity. Topical treatment with ointments containing ethanol extract, its ethyl acetate fraction and sesquiterpene lactones significantly reduced carrageenan-induced mice paw oedema. In vitro assays demonstrated that Lyc inhibited interferon -γ/lipopolysaccharide -stimulated nitric oxide (NO) production in J774A.1 macrophages and increased production of IL-10 anti-inflammatory cytokine. The reduction of tumor necrosis factor-α (TNF-α) production by EreC was accompanied by an increased production of IL-10 in a concentration-dependent manner in J774A.1 macrophages. The anti-inflammatory effect of Lyc seems to involve the inhibition of production of NO and increased production of IL-10. The mechanism of the effect of EreC on the reduction of carrageenan-induced paw oedema may be attributed to inhibition of production of TNF-α and stimulation of IL-10 production. The results corroborate the use of ethanol extract from Lychnophora trichocarpha in folk medicine for anti-inflammatory action and indicate that the topical route is suitable for use.

    Since ages Mallotus peltatus (Geist) Muell. Arg. var acuminatus (Euphorbiaceae) leaf and stem bark is used in folk medicine to cure intestinal ailments and skin infections. In several intestinal ailments, localized inflammation is of common occurrence and hence we have evaluated the antimicrobial as well as anti-inflammatory activity of M. peltatus leaf extract. The crude methanol extract of M. peltatus leaves was found to be active against Staphylococcus aureus, Staphylococcus saprophyticus, Streptococcus faecalis, Bacillus subtilis, Escherichia coli and Proteus mirabilis and the dermatophytic fungi Microsporum gypseum. The minimum inhibitory concentration (MIC) ranges from 128 to 2000 microg ml(-1) for bacteria and 128 mg ml(-1) for fungi, while the minimum bactericidal concentration (MBC) was 2-4-fold higher than MIC. The methanol-water fraction of the extract showed similar activity against Staphylococcus, Streptococcus, Bacillus and Proteus isolates. The anti-inflammatory activity of the extract against carrageenan (acute model) and dextran-induced (subacute model) rat paw oedema and cotton pellet-induced granuloma (chronic model) in rats were studied using indomethacin (10 mg kg(-1)), a nonsteroid anti-inflammatory drug, as standard. The methanol extract at 200 and 400 mg kg(-1), and the n-butanol fractions A and B at 25 mg kg(-1), exhibited significant anti-inflammatory activity in Albino rats, compared with indomethacin. Phytochemical study revealed the presence of tannins, saponins, terpenoids, steroids and reducing sugars in the crude extract while the n-butanol fractions showed the presence of ursolic acid, beta-sitosterol and some fatty acids as major compounds. Further study with fractions showed that the antibacterial and anti-inflammatory activity is due to either fraction A (ursolic acid) alone or the combination of fractions A and B (beta-sitosterol and fatty acids) of the extract.

Objective To characterize the kinetic response of pro-inflammatory cytokines released by human NP cells to TNFα stimulation and the effectiveness of multiple anti-inflammatories with 3 sub-studies: Timecourse, Same-time blocking, Delayed blocking. Summary of Background Data Chronic inflammation is a key component of painful intervertebral disc (IVD) degeneration. Improved efficacy of anti-inflammatories requires better understanding of how quickly NP cells produce pro-inflammatory cytokines and which pro-inflammatory mediators are most therapeutically advantageous to target. Methods Degenerated human NP cells (n=10) were cultured in alginate with or without TNFα (10ng/mL). Cells were incubated with one of four anti-inflammatories (anti-IL-6 receptor/atlizumab, IL-1 receptor anatagonist, anti-TNFα/infliximab and sodium pentosan polysulfate/PPS) in two blocking-studies designed to determine how intervention timing influences drug efficacy. Cell viability, protein and gene expression for IL-1β, IL-6 & IL-8 were assessed. Results Timecourse: TNFα substantially increased the amount of IL-6, IL-8 & IL-1β, with IL-1β and IL-8 reaching equilibrium within ~72 hours (IL-1β: 111±40pg/mL, IL-8: 8478±957pg/mL), and IL-6 not reaching steady state after 144 hours (1570±435 pg/mL). Anti-TNFα treatment was most effective at reducing the expression of all cytokines measured when added at the same time as TNFα stimulation. Similar trends were observed when drugs were added 72 hours after TNFα stimulation, however, no anti-inflammatories significantly reduced cytokine levels compared to TNF control. Conclusion IL-1β, IL-6 and IL-8 were expressed at different rates and magnitudes suggesting different roles for these cytokines in disease

    D-002, a mixture of six higher aliphatic alcohols purified from beeswax, displayed anti-inflammatory effects in carrageenan-induced pleurisy and cotton pellet granuloma in rats. The aim of the present study was to confirm the anti-inflammatory properties of D-002 and to explore its potential analgesic effects. Xylene-induced mouse ear oedema was used to assess the anti-inflammatory effect, acetic acid-induced writhing and hot plate responses for the analgesic activity, and the open field and horizontal rotarod tests for motor performance. For anti-inflammatory tests, mice were randomised into a negative vehicle control and five xylene-treated groups: the vehicle, D-002 (25, 50 and 200 mg/kg) and indomethacin 1 mg/kg (reference drug). Treatments were given for 15 days. Effects on oedema formation and myeloperoxidase (MPO) activity were tested. For analgesia and motor performance tests, mice were randomised into a vehicle control and D-002-treated groups (25, 50 and 200 mg/kg). Two sets of experiments were done, which included acute and repeat (15 days) dosing. D-002 (25, 50 and 200 mg/kg) significantly decreased xylene-induced ear oedema (44.7, 60.8 and 76.4%, respectively) and the increase of MPO activity induced by xylene (38.0, 47.0 and 57.0%, respectively), while indomethacin significantly inhibited xylene-induced oedema (59.9%) and MPO activity (57.5%). Single and repeat doses of D-002 (25, 50 and 200 mg/kg) decreased the acetic acid-induced writhing responses by 21.2, 28.2 and 40.1%, for the single doses; 25.2, 35.1 and 43.2%, respectively, for the repeat doses, but did not affect the hot plate, open field and rotarod behaviours. Aspirin 100 mg/kg significantly decreased acetic acid-induced abdominal constrictions and morphine (5 mg/kg) significantly increased the latency of the hot plate response. This study confirmed the anti-inflammatory effects of D-002 and demonstrated its analgesic effects on the acetic acid-induced writhing, but not on the hot plate

    Full Text Available Abstract Background Nanocrystalline silver dressings have anti-inflammatory activity, unlike solutions containing Ag+ only, which may be due to dissolution of multiple silver species. These dressings can only be used to treat surfaces. Thus, silver-containing solutions with nanocrystalline silver properties could be valuable for treating hard-to-dress surfaces and inflammatory conditions of the lungs and bowels. This study tested nanocrystalline silver-derived solutions for anti-inflammatory activity. Methods Inflammation was induced on porcine backs using dinitrochlorobenzene. Negative and positive controls were treated with distilled water. Experimental groups were treated with solutions generated by dissolving nanocrystalline silver in distilled water adjusted to starting pHs of 4 (using CO2, 5.6 (as is, 7, and 9 (using Ca(OH2. Solution samples were analyzed for total silver. Daily imaging, biopsying, erythema and oedema scoring, and treatments were performed for three days. Biopsies were processed for histology, immunohistochemistry (for IL-4, IL-8, IL-10, TNF-α, EGF, KGF, KGF-2, and apoptotic cells, and zymography (MMP-2 and -9. One-way ANOVAs with Tukey-Kramer post tests were used for statistical analyses. Results Animals treated with pH 7 and 9 solutions showed clear visual improvements. pH 9 solutions resulted in the most significant reductions in erythema and oedema scores. pH 4 and 7 solutions also reduced oedema scores. Histologically, all treatment groups demonstrated enhanced re-epithelialisation, with decreased inflammation. At 24 h, pMMP-2 expression was significantly lowered with pH 5.6 and 9 treatments, as was aMMP-2 expression with pH 9 treatments. In general, treatment with silver-containing solutions resulted in decreased TNF-α and IL-8 expression, with increased IL-4, EGF, KGF, and KGF-2 expression. At 24 h, apoptotic cells were detected mostly in the dermis with pH 4 and 9 treatments, nowhere with pH 5.6, and in both the

    2012-04-01

    Alpha-1 antitrypsin (AAT) has long been thought of as an important anti-protease in the lung where it is known to decrease the destructive effects of major proteases such as neutrophil elastase. In recent years, the perception of this protein in this simple one dimensional capacity as an anti-protease has evolved and it is now recognised that AAT has significant anti-inflammatory properties affecting a wide range of inflammatory cells, leading to its potential therapeutic use in a number of important diseases. This present review aims to discuss the described anti-inflammatory actions of AAT in modulating key immune cell functions, delineate known signalling pathways and specifically to identify the models of disease in which AAT has been shown to be effective as a therapy.

  11. Anti-Inflammatory Nutrition as a Pharmacological Approach to Treat Obesity

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available Obesity is a multifactorial condition resulting from improper balances of hormones and gene expression induced by the diet. Obesity also has a strong inflammatory component that can be driven by diet-induced increases in arachidonic acid. The purpose of this paper is to discuss the molecular targets that can be addressed by anti-inflammatory nutrition. These molecular targets range from reduction of proinflammatory eicosanoids to the modulation of features of the innate immune system, such as toll-like receptors and gene transcription factors. From knowledge of the impact of these dietary nutrients on these various molecular targets, it becomes possible to develop a general outline of an anti-inflammatory diet that can offer a unique synergism with more traditional pharmacological approaches in treating obesity and its associated comorbidities.

    Full Text Available Carotenoids extracted from dried peppers were evaluated for their antioxidant, analgesic, and anti-inflammatory activities. Peppers had a substantial carotenoid content: guajillo 3406±4 μg/g, pasilla 2933±1 μg/g, and ancho 1437±6 μg/g of sample in dry weight basis. A complex mixture of carotenoids was discovered in each pepper extract. The TLC analysis revealed the presence of chlorophylls in the pigment extract from pasilla and ancho peppers. Guajillo pepper carotenoid extracts exhibited good antioxidant activity and had the best scavenging capacity for the DPPH+ cation (24.2%. They also exhibited significant peripheral analgesic activity at 5, 20, and 80 mg/kg and induced central analgesia at 80 mg/kg. The results suggest that the carotenoids in dried guajillo peppers have significant analgesic and anti-inflammatory benefits and could be useful for pain and inflammation relief.

    The ethanol leaf extract of Cymbidium aloifolium (L.) was evaluated for its analgesic and antiinflammatory activities. The extract, at the dose of 200 and 400 mg kg(-1) body weight, exerted the analgesic activity by observing the number of abdominal contractions and anti-inflammatory activity against Carrageenin induced paw edema in mice by measuring the paw volume. The ethanolic extract of Cymbidium aloifolium (L.) showed statistically significant (p < 0.05) reduction of percentage of writhing of 33.57 and 61.31% at 200 and 400 mg kg(-1) oral dose, respectively, when compared to negative control. The Ethanolic plant extract also showed significant (p < 0.05) dose dependent reduction of mean increase of formation of paw edema. The results of the experiment and its statistical analysis showed that the ethanolic plant extract had shown significant (p < 0.05) dose dependent analgesic and anti-inflammatory activities when compared to the control.

    The alkaloid 2-methoxy-4-(7-methoxy-1,2,3,4-tetrahydroisoquinolin-1-yl)phenol (MHTP) was synthesized to prospect new compounds with therapeutic properties. Thus, the goal of this study was to evaluate the MHTP anti-inflammatory effect by in vivo and in vitro assays. The MHTP toxicity was analyzed. We found that MHTP pre-treatment (2.5-10 mg/kg) showed antiedematogenic effect (p alkaloid also reduced (p alkaloid, MHTP has anti-inflammatory effect by inhibiting PGE2 function as well as inhibiting inflammatory cell migration to the inflamed site and attenuated the acute lung injury disease by inhibiting the migration of neutrophil to the lung. However, further studies will be carried out to demonstrate the mechanisms of action of the molecule and explore its potential as a future drug to treat inflammatory processes.

    Four flavanonols (1-4), one xanthone (5), and three flavonoid glycosides (6-8), were isolated from the leaves and stems of Desmodium caudatum. Their structures were elucidated by comparing spectroscopic data with reported values. The anti-inflammatory activity of the isolated compounds was investigated in lipopolysaccharide (LPS)-stimulated bone marrow-derived dendritic cells. Among them, compounds 1 and 2 exhibited inhibitory effects on LPS-induced IL-6, IL-12 p40, and TNF-α production with IC50 values ranging from 6.0 to 29.4 μM. Compound 5 exhibited 1,1-diphenyl-2-picrylhydrazyl radical and intracellular reactive oxygen species scavenging activity in human HaCaT keratinocytes. These results warrant further studies of the potential anti-inflammatory and antioxidant benefits of compounds from D. caudatum.

  17. Increased temperature and entropy production in cancer: the role of anti-inflammatory drugs.

    Science.gov (United States)

    Pitt, Michael A

    2015-02-01

    Some cancers have been shown to have a higher temperature than surrounding normal tissue. This higher temperature is due to heat generated internally in the cancer. The higher temperature of cancer (compared to surrounding tissue) enables a thermodynamic analysis to be carried out. Here I show that there is increased entropy production in cancer compared with surrounding tissue. This is termed excess entropy production. The excess entropy production is expressed in terms of heat flow from the cancer to surrounding tissue and enzymic reactions in the cancer and surrounding tissue. The excess entropy production in cancer drives it away from the stationary state that is characterised by minimum entropy production. Treatments that reduce inflammation (and therefore temperature) should drive a cancer towards the stationary state. Anti-inflammatory agents, such as aspirin, other non-steroidal anti-inflammatory drugs, corticosteroids and also thyroxine analogues have been shown (using various criteria) to reduce the progress of cancer.

    2012-01-01

    Aspirin and non-steroidal anti-inflammatory drugs (NSAIDS) may prevent sporadic colonic neoplasia and reduce the polyp burden in familial adenomatous polyposis. A 41-year-old pharmacologist with no family history of intestinal polyps or cancer chronically consumed daily aspirin and other non-steroidal anti-inflammatory drugs for decades despite recurrent and multiple gastric ulcers. A cancerous polyp in the colon was endoscopically resected. Over the next 2 decades, almost 50 adenomatous polyps were removed from the rest of his colon and duodenum, typical of an attenuated form of adenomatous polyposis. Chronic and habitual use of aspirin or NSAIDS may have important significance in delaying the appearance of adenomas. The observations here emphasize the important implications for clinical risk assessment in screening programs designed to detect or prevent colon cancer.

    Glucocorticoids have important immunosupressive properties, being used as anti-inflammatory therapeutic agents in a wide range of inflammatory and auto-immune pathologies. One of the best studied mechanisms by which glucocorticoids exert most of their anti-inflammatory actions involves the induction of the synthesis and the secretion of the mediator and effector protein annexin 1 (ANXA1). Here we review the molecular and cellular pathways involved on the glucocorticoid-induced synthesis and secretion of ANXA1 in a variety of cell types. Since its discovery as an anti-phospholipase A2 protein, ANXA1 has come a long way to encompass a wide range of cellular effects, the most relevant ones being those that directly modulate the inflammatory response. The results presented in this review open the way to further pharmacological studies which will allow the identification of the role of ANXA1 in inflamatory pathologies, namely rheumatoid arthritis.

    Full Text Available Antimetastatic and anti-inflammatory activities of Ocimum sanctum essential oil (OSEO have been assessed in this study. OSEO at the concentration of 250 μg/mL and above showed a significant (P*<0.05 decrease in the number of migrated cancer cells. In addition, OSEO at concentration of 250 μg/mL and above suppressed MMP-9 activity in lipopolysaccharide (LPS induced inflammatory cells. A dose-dependent downregulation of MMP-9 expression was observed with the treatment of OSEO compared to the control. Our findings indicate that OSEO has both antimetastatic and anti-inflammatory potentials, advocating further investigation for clinical applications in the treatment of inflammation associated cancer.

    Urolithin A is a major metabolite produced by rats and humans after consumption of pomegranate juice or pure ellagitannin geraniin. In this study, we investigated the anti-inflammatory effect of urolithin A on carrageenan-induced paw edema in mice. The volume of paw edema was reduced at 1h after oral administration of urolithin A. In addition, plasma in treated mice exhibited significant oxygen radical antioxidant capacity (ORAC) scores with high plasma levels of the unconjugated form at 1h after oral administration of urolithin A. These results indicate strong associations among plasma urolithin A levels, the plasma ORAC scores, and anti-inflammatory effects and may help explain a mechanism by which ellagitannins confer protection against inflammatory diseases.

    Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used in the management of pain and endotoxaemia associated with colic in the horse. While NSAIDs effectively treat the symptoms of colic, there is evidence to suggest that their administration is associated with adverse gastrointestinal effects including right dorsal colitis and inhibition of mucosal barrier healing. Several studies have examined the pathophysiology of NSAID associated effects on the large and small intestine in an effort to avoid these complications and identify effective alternative medications. Differences in the response of the large and small intestines to injury and NSAID treatment have been identified. Flunixin meglumine has been shown in the small intestine to inhibit barrier function recovery and increase permeability to lipopolysaccharide (LPS). A range of NSAIDs has been examined in the small intestine and experimental evidence suggests that those NSAIDs with cyclooxygenase independent anti-inflammatory effects or a COX-2 selective mode of action may offer significant advantages over traditional NSAIDs.

    The aim of this study was to investigate novel chalcones with potent anti-inflammatory activities in vivo. Chalcone and two chalcone analogues (compound 5 and 9) were evaluated using a caudal fin-wounded transgenic zebrafish line "Tg(mpx:gfp)" to visualize the effect of neutrophil recruitment dynamically. Results showed that treatment with compound 9 not only affected wound-induced neutrophil recruitment, but also affected Mpx enzymatic activity. Moreover, protein expression levels of pro-inflammatory factors (Mpx, NFκB, and TNFα) were also regulated by compound 9. Taken together, our results provide in vivo evidence of the anti-inflammatory effects of synthesized chalcone analogues on wound-induced inflammation.

    Full Text Available Acupuncture has been used for millennia to treat allergic diseases including both intermittent rhinitis and persistent rhinitis. Besides the research on the efficacy and safety of acupuncture treatment for allergic rhinitis, research has also investigated how acupuncture might modulate immune function to exert anti-inflammatory effects. A proposed model has previously hypothesized that acupuncture might downregulate proinflammatory neuropeptides, proinflammatory cytokines, and neurotrophins, modulating transient receptor potential vallinoid (TRPV1, a G-protein coupled receptor which plays a central role in allergic rhinitis. Recent research has been largely supportive of this model. New advances in research include the discovery of a novel cholinergic anti-inflammatory pathway activated by acupuncture. A chemokine-mediated proliferation of opioid-containing macrophages in inflamed tissues, in response to acupuncture, has also been demonstrated for the first time. Further research on the complex cross talk between receptors during inflammation is also helping to elucidate the mediators and signalling pathways activated by acupuncture.

    Hexane, chloroform and methanol extracts of seven herbal drugs used in the folk medicine of Central America against skin disorders (Aristolochia trilobata leaves and bark, Bursera simaruba bark, Hamelia patens leaves, Piper amalago leaves, and Syngonium podophyllum leaves and bark) were evaluated for their topical anti-inflammatory activity against the Croton oil-induced ear oedema in mice. Most of the extracts induced a dose-dependent oedema reduction. The chloroform extract of almost all the drugs exhibited interesting activities with ID(50) values ranging between 108 and 498 micro g/cm(2), comparable to that of indomethacin (93 micro g/cm(2)). Therefore, the tested plants are promising sources of principles with high anti-inflammatory activity.

    Antibodies play a central role in immunity by forming an interface with the innate immune system and, typically, mediate proinflammatory activity. We describe a novel posttranslational modification that leads to anti-inflammatory activity of antibodies of immunoglobulin G, isotype 4 (IgG4). IgG4 antibodies are dynamic molecules that exchange Fab arms by swapping a heavy chain and attached light chain (half-molecule) with a heavy-light chain pair from another molecule, which results in bispecific antibodies. Mutagenesis studies revealed that the third constant domain is critical for this activity. The impact of IgG4 Fab arm exchange was confirmed in vivo in a rhesus monkey model with experimental autoimmune myasthenia gravis. IgG4 Fab arm exchange is suggested to be an important biological mechanism that provides the basis for the anti-inflammatory activity attributed to IgG4 antibodies.

    Dried hydro-alcoholic extract of Peumus boldus (Monimiaceae) has been evaluated for hepatoprotective, choleretic and anti-inflammatory effects in mice and rats, in order to validate or to invalidate traditional therapeutic indications. This extract exerted a significant hepatoprotection of tert-butyl hydroperoxide-induced hepatotoxicity in isolated rat hepatocytes (in vitro technique) by reducing the lipid peroxidation and the enzymatic leakage of LDH; this in vitro efficacy was reinforced by a significant hepatoprotection on CCl4-induced hepatotoxicity in mice (in vivo technique), the plant extract reducing the enzymatic leakage of ALAT. Boldine, the main alkaloid of P. boldus appears to be implicated in this hepatoprotective activity. Choleretic effects, often mentioned in traditional indications, have not been confirmed in rats. Finally, significant and dose-dependent anti-inflammatory effects were obtained on an acute inflammatory process (carrageenan-induced edema test in rats). Boldine does not appear to be involved in such properties.

    The ability of different non-steroidal anti-inflammatory drugs (diclofenac, indomethacin, ketoprofen, naproxen and piroxicam) to inhibit gastric prostaglandin E2 production in the rat was compared with their damaging potential on gastric mucosa. The influence of treatment with zinc acexamate (ZAC) on these two parameters was also determined. ZAC treatment significantly decreased the degree of gastric damage elicited by all the antiinflammatories tested. The experimental data confirm the complexity of the gastrolesive effect exerted by anti-inflammatory drugs and that only part of such effect would be related with their inhibition of prostaglandin synthesis. These results indicate that the gastroprotection of ZAC does not exclusively depend on the effect on the synthesis of prostaglandins by the gastric mucosa, yet it can additionally be exerted through alternative mechanisms.

    Sesquiterpene acids are natural products that, in contrast with the thoroughly studied sesquiterpene lactones, have received little pharmacological attention. A good source of this class of compounds is Inula viscosa (Asteraceae), a plant with documented anti-inflammatory effects. The present paper gives the results of our investigations on the biochemical mechanisms involved in the anti-inflammatory activity of one such compound, dehydrocostic acid. The most salient findings were that in vitro dehydrocostic acid inhibits leukotriene B(4) production (IC(50)=22 microM), elastase activity (IC(50)=43 microM) and bee venom phospholipase A(2) activity (IC(50)=17 microM). Furthermore, this sesquiterpenoid was effective on some models of acute edema induced by PLA(2) and 12-O-tetradecanoylphorbol 13-acetate (TPA) Comparison of these data with that known for ilicic acid firmly suggests that the presence of a semiplanar ring A is essential for an improved inhibitory activity on inflammatory mediators.

    Full Text Available Summary: The flowers of Caesalpinia pulcherrima were extracted with methanol to determine their analgesic and anti-inflammatory activities. Intraperitoneal administration of methanolic extract (75, 150 and 225 mg/kg produced significant analgesic activity in acetic acid-induced writhing, tail immersion test and hot plate tests and anti-inflammatory effect against carrageenan-induced paw edema in experimental animals. Industrial relevance: The herbal medicines are getting more importance in the treatment of inflammation because of the side effect of the current therapy used to treat those inflammation using synthetic drugs. Herbal medicines have less side effects and less costly when compared to the synthetic drugs. The present study will help the industry to produce herbal drug with less side effect, less costly affordable and more effective in the treatment of pain and inflammation. Finally the phytochemical screening or elucidation of the bioactive compounds from the plant would be effective drug against pain and inflammation.

    Heterogeneity and functional specialization among skin-resident macrophages are incompletely understood. In this study, we describe a novel subset of murine dermal perivascular macrophages that extend protrusions across the endothelial junctions in steady-state and capture blood-borne macromolecules. Unlike other skin-resident macrophages that are reconstituted by bone marrow-derived progenitors after a genotoxic insult, these cells are replenished by an extramedullary radio-resistant and UV-sensitive Bmi1+ progenitor. Furthermore, they possess a distinctive anti-inflammatory transcriptional profile, which cannot be polarized under inflammatory conditions, and are involved in repair and remodeling functions for which other skin-resident macrophages appear dispensable. Based on all their properties, we define these macrophages as Skin Transendothelial Radio-resistant Anti-inflammatory Macrophages (STREAM) and postulate that their preservation is important for skin homeostasis.

    Inflammatory response plays an important role not only in the normal physiology, but also in the pathology of certain diseases such as cancers. In our previous study, we found a novel derivative of pterostilbene (PTER), to be an effective inducer of apoptosis in human breast and prostate cancer cells affecting various cellular targets. Herein, we further attempted to investigate its anti-inflammatory potential followed by its probable mode of action. The newly developed compound was tested for its anti-inflammatory actions in lipopolysaccharide (LPS) stimulated RAW264.7 macrophages and carrageenan induced rat paw edema models. Our data showed that the derivative inhibited the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) as well as the downstream products like nitric oxide (NO) and PGE2, at much lower doses as compared to PTER. This effect was found to be associated with the inhibition of phosphorylation/degradation of IκB-α and nuclear translocation of the p-NFκB p65. Moreover, inhibition of mitogen-activated protein kinases (MAPKs) and activator protein-1 (AP-1) was also observed. In addition, the newly developed compound also reduced the paw edema, the tissue content of NO, PGE2 and expression of iNOS and COX-2 proteins within the tissues after λ-carrageenan stimulation. Taken together, our findings provide the possibility that the PTER derivative might have enhanced cancer chemopreventive potential based on its stronger anti-NFκB and anti-inflammatory activities as compared to its natural counterpart, i.e., PTER. Thus, this compound can be used towards the development of an effective anti-inflammatory agent.

    Full Text Available Abstract Background Pyrexia, algesia and inflammation are associated with several pathological conditions. Synthetic drugs available for the treatment of these conditions cause multiple unwanted effects. Several studies are ongoing worldwide to find natural healing agents with better safety profile. The current study was thus aimed at evaluating antipyretic, analgesic and anti-inflammatory activities of the methanolic extract of whole plant of V. betonicifolia (VBME. Methods VBME was employed to assess antipyretic activity in yeast induced hyperthermia. Analgesic profile was ascertained in acetic acid induced writhing, hot plat and tail immersion test. Nevertheless, the anti-inflammatory activity was tested in carrageenan induced paw edema and histamine induced inflammatory tests. BALB/c mice were used at test doses of 100, 200 and 300mg/kg body weight intra peritoneally (i.p. Results In yeast induced pyrexia, VBME demonstrated dose dependently (78.23% protection at 300mg/kg, similar to standard drug, paracetamol (90% at 150mg/kg i.p. VBME showed a dose dependent analgesia in various pain models i.e. acetic acid, hot plat and tail immersion having 78.90%, 69.96% and 68.58% protection respectively at 300mg/kg. However, the analgesic action of VBME was completely antagonized by the injection of naloxone like opiate antagonists. Similarly carrageenan and histamine induces inflammation was significantly antagonized by VBME, 66.30% and 60.80% respectively at 300mg/kg. Conclusions It is concluded that VBME has marked antipyretic, analgesic and anti-inflammatory activities in various animal models and this strongly supports the ethnopharmacological uses of Viola betonicifolia as antipyretic, analgesic and anti-inflammatory plant.

    Full Text Available Background: In mammals lipoic acid (LA and its reduced form dihydrolipoic acid (DHLA function as cofactors for multienzymatic complexes catalyzing the decarboxylation of α-ketoacids. Moreover, LA is used as a drug in a variety of diseases including inflammatory diseases. The aim of the study was to examine anti-inflammatory properties of LA metabolites.Material/methods:The present paper reports the chemical synthesis of 2,4-bismethylthio-butanoic acid (BMTBA and tetranor-dihydrolipoic acid (tetranor-DHLA. BMTBA is one of the biotransformation products of LA, while tetranor-DHLA is an analogue of DHLA. Structural identity of these compounds was confirmed by 1H NMR. These compounds were assessed for their anti-inflammatory activity in mice. For this purpose, the zymosan-induced peritonitis and the carrageenan-induced hind paw edema animal models were applied.Results/conclusions: The obtained results indicated that the early vascular permeability measured at 30 min of zymosan-induced peritonitis was significantly inhibited in groups receiving BMTBA (10, 30, 50 mg/kg. The early infiltration of neutrophils measured at 4 hours of zymosan-induced peritonitis was inhibited in the group receiving BMTBA (50 mg/kg and tetranor-DHLA (50 mg/kg. The results indicated that the increase in paw edema was significantly inhibited in the groups receiving BMTBA (50, 100 mg/kg and tetranor-DHLA (30, 50 mg/kg. In summary, the present studies clearly demonstrated that both BMTBA and tetranor-DHLA were able to act as anti-inflammatory agents. This is the first study examining in vivo the anti-inflammatory properties of LA metabolites.

    Objective: To evaluate the anti-oxidant and anti-inflammatory activity of leaf extracts and fractions of Mangifera indica in in vitro conditions. Methods: In vitro DPPH radical scavenging activity and lipoxygenase (LOX) inhibition assays were used to evaluate the anti-oxidant and anti-inflammatory activities respectively. Methanolic extract (MEMI), successive water extract (SWMI) and ethyl acetate fraction (EMEMI), n-butanol fraction (BMEMI) and water soluble fraction (WMEMI) of methanolic extract were evaluated along with respective reference standards. Results: In in vitro DPPH radical scavenging activity, the MEMI, EMEMI and BMEMI have offered significant antioxidant activity with IC50 values of 13.37, 3.55 and 14.19 μg/mL respectively. Gallic acid, a reference standard showed significant antioxidant activity with IC50 value of 1.88 and found to be more potent compared to all the extracts and fractions. In in vitro LOX inhibition assay, the MEMI, EMEMI and BMEMI have showed significant inhibition of LOX enzyme activity with IC50 values of 96.71, 63.21 and 107.44 μg/mL respectively. While, reference drug Indomethacin also offered significant inhibition against LOX enzyme activity with IC50 of 57.75. Furthermore, MEMI was found to more potent than SWMI and among the fractions EMEMI was found to possess more potent antioxidant and anti-inflammatory activity. Conclusions: These findings suggest that the MEMI and EMEMI possess potent anti-oxidant and anti-inflammatory activities in in vitro conditions.

    Meloxicam (MLX) is a poorly water-soluble non steroidal anti-inflammatory drug (NSAID). The main objective of the present work was to enhance the dissolution of MLX and thus its bioavailability by the aid of additives. The novelty of this work rises from the utilization of spray drying technology to produce micro particulates solid dispersion systems containing MLX in the presence of small amount of additives. Differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FT-IR), and Scan Electron Microscope (SEM) were used for studying the physico-chemical and morphological properties of MLX samples. The dissolution of MLX samples was investigated in two different pH media. The morphology of MLX solid dispersion micro-particles was spherical in shape according to SEM. FT-IR profiles indicated that a complex was formed between MLX and the additives. DSC patterns of the MLX micro-particles suggested a reduction in the crystallinity of MLX and probability of presence of an interaction between MLX and the additives. The rate of dissolution of the spray-dried MLX enhanced as compared with the unprocessed MLX in both acidic and neutral media. It was found that 100% of the added MLX released within 5 min in phosphate buffer dissolution medium (pH 7.4) compared to that of the unprocessed MLX (15% in 60 min). Such increase rate in the dissolution of the spray dried MLX could be attributed to the increase in wettability of MLX particles and the hydrophilic nature of the additives. The anti-inflammatory effect of the spray dried MLX was explored using formalin induced rat paw edema model. The spray-dried samples showed an increase in the anti-inflammatory activity of MLX as compared to the unprocessed MLX. This work reveals that the spray drying technique is suitable for preparation of micro-particles with improved dissolution and anti-inflammatory effect of MLX.

    Chronic inflammation contributes to multiple ageing-related musculoskeletal and neurodegenerative diseases, cardiovascular diseases, asthma, rheumatoid arthritis, and inflammatory bowel disease. More recently, chronic neuroinflammation has been attributed to Parkinson's and Alzheimer's disease and autism-spectrum and obsessive-compulsive disorders. To date, pharmacotherapy of inflammatory conditions is based mainly on nonsteroidal anti-inflammatory drugs which in contrast to cytokine-suppressive anti-inflammatory drugs do not influence the production of cytokines such as tumour necrosis factor-α or nitric oxide. However, their prolonged use can cause gastrointestinal toxicity and promote adverse events such as high blood pressure, congestive heart failure, and thrombosis. Hence, there is a critical need to develop novel and safer nonsteroidal anti-inflammatory drugs possessing alternate mechanism of action. In this study, plants used by the Dharawal Aboriginal people in Australia for the treatment of inflammatory conditions, for example, asthma, arthritis, rheumatism, fever, oedema, eye inflammation, and inflammation of bladder and related inflammatory diseases, were evaluated for their anti-inflammatory activity in vitro. Ethanolic extracts from 17 Eucalyptus spp. (Myrtaceae) were assessed for their capacity to inhibit nitric oxide and tumor necrosis factor-α production in RAW 264.7 macrophages. Eucalyptus benthamii showed the most potent nitric oxide inhibitory effect (IC50  5.57 ± 1.4 µg/mL), whilst E. bosistoana, E. botryoides, E. saligna, E. smithii, E. umbra, and E. viminalis exhibited nitric oxide inhibition values between 7.58 and 19.77 µg/mL.

    Chronic inflammation contributes to multiple ageing-related musculoskeletal and neurodegenerative diseases, cardiovascular diseases, asthma, rheumatoid arthritis, and inflammatory bowel disease. More recently, chronic neuroinflammation has been attributed to Parkinson's and Alzheimer's disease and autism-spectrum and obsessive-compulsive disorders. To date, pharmacotherapy of inflammatory conditions is based mainly on nonsteroidal anti-inflammatory drugs which in contrast to cytokine-suppressive anti-inflammatory drugs do not influence the production of cytokines such as tumour necrosis factor-α or nitric oxide. However, their prolonged use can cause gastrointestinal toxicity and promote adverse events such as high blood pressure, congestive heart failure, and thrombosis. Hence, there is a critical need to develop novel and safer nonsteroidal anti-inflammatory drugs possessing alternate mechanism of action. In this study, plants used by the Dharawal Aboriginal people in Australia for the treatment of inflammatory conditions, for example, asthma, arthritis, rheumatism, fever, oedema, eye inflammation, and inflammation of bladder and related inflammatory diseases, were evaluated for their anti-inflammatory activity in vitro. Ethanolic extracts from 17 Eucalyptus spp. (Myrtaceae) were assessed for their capacity to inhibit nitric oxide and tumor necrosis factor-α production in RAW 264.7 macrophages. Eucalyptus benthamii showed the most potent nitric oxide inhibitory effect (IC50  5.57 ± 1.4 µg/mL), whilst E. bosistoana, E. botryoides, E. saligna, E. smithii, E. umbra, and E. viminalis exhibited nitric oxide inhibition values between 7.58 and 19.77 µg/mL.

    Neuroinflammation plays an important role in the progression of various neurodegenerative diseases. In this study, we investigated the anti-inflammatory effects of lonchocarpine, a natural compound isolated from Abrus precatorius, under in vitro and in vivo neuroinflammatory conditions induced by challenge with lipopolysaccharide (LPS)- or polyinosinic-polycytidylic acid (poly(I:C)). Lonchocarpine suppressed the expression of iNOS and proinflammatory cytokines in LPS or poly(I:C)-stimulated BV2 microglial cells. These anti-inflammatory effects were verified in brains of mice with systemic inflammation induced by administration of LPS or poly(I:C). Lonchocarpine reduced the number of Iba-1-positive activated microglia, and suppressed the mRNA expression of various proinflammatory markers in the cortex of LPS- or poly(I:C)-injected mice. Molecular mechanistic experiments showed that lonchocarpine inhibited NF-κB activity by reducing the phosphorylation and degradation of IκBα in LPS- or poly(I:C)-stimulated BV2 cells. Analysis of further upstream signaling pathways in LPS-stimulated microglia showed that lonchocarpine inhibited the phosphorylation of IκB kinase and TGFβ-activated kinase 1 (TAK1). Moreover, lonchocarpine suppressed the interaction of myeloid differentiation factor 88 (MyD88) and intereleukin-1 receptor-associated kinase 4 (IRAK4). These data suggest that toll-like receptor 4 downstream signals such as MyD88/IRAK4-TAK1-NF-κB are at least partly involved in the anti-inflammatory mechanism of lonchocarpine in LPS-stimulated microglia. Its strong anti-inflammatory effects may make lonchocarpine an effective preventative drug for neuroinflammatory disorders that are associated with systemic inflammation.

    Full Text Available Background. Heparin, used clinically as an anticoagulant, also has anti-inflammatory properties. The purpose of this systematic review was to provide a comprehensive review regarding the efficacy and safety of heparin and its derivatives as anti-inflammatory agents. Methods. We searched the following databases up to March 2012: Pub Med, Scopus, Web of Science, Ovid, Elsevier, and Google Scholar using combination of Mesh terms. Randomized Clinical Trials (RCTs and trials with quasi-experimental design in clinical setting published in English were included. Quality assessments of RCTs were performed using Jadad score and Consolidated Standards of Reporting Trials (CONSORT checklist. Results. A total of 280 relevant studies were reviewed and 57 studies met the inclusion criteria. Among them 48 studies were RCTs. About 65% of articles had score of 3 and higher according to Jadad score. Twelve studies had a quality score > 40% according to CONSORT items. Asthma (n=7, inflammatory bowel disease (n=5, cardiopulmonary bypass (n=8, and cataract surgery (n=6 were the most studied disease condition. Forty studies use unfractionated heparin (UFH for intervention; the remaining studies use low molecular weight heparin (LMWH. Conclusion. Despite the conflicting results, heparin seems to be a safe and effective anti-inflammatory agent; although it is shown that heparin can decrease the level of inflammatory biomarkers and improves patient conditions, still more data from larger rigorously designed studies are needed to support use of heparin as an anti-inflammatory agent in clinical setting. However, because of the association between inflammation, atherogenesis, thrombogenesis, and cell proliferation, heparin and related compounds with pleiotropic effects may have greater therapeutic efficacy than compounds acting against a single target.

    A number of acute and chronic inflammatory disorders are amenable to varying degrees of therapeutic control with the administration of nonspecific anti-inflammatory drugs. An evaluation of these suppressive agents in the field of rheumatic diseases and practical suggestions regarding their administration are presented. Eight synthetically modified corticosteroid compounds are available commercially. Each of them exhibits qualitative differences in one or several physiologic actions, each has certain advantages and disadvantages in therapy, and each shares the major deterrent features of corticosteroids. Prednisone, prednisolone, methylprednisolone, fluprednisolone and paramethasone have similar therapeutic indices, and there is little choice between them for the usual rheumatoid patient requiring steroid therapy. Conversely, the therapeutic indices of dexamethasone, betamethasone and triamcinolone are lower than that of prednisolone; they are less desirable for routine use and should be reserved for specially selected cases. Salicylates are preferred to adrenocortical steroids in the treatment of the ordinary patient with acute rheumatic fever. Steroid therapy should be reserved for resistant cases and for those with significant carditis. Salicylates are mainstays for pain relief in rheumatoid arthritis, but with the analgesic doses usually employed their anti-inflammatory action is slight.Phenylbutazone is a highly useful anti-inflammatory agent, especially in management of acute gouty arthritis and ankylosing (rheumatoid) spondylitis; its metabolite, oxyphenylbutazone, does not exhibit clear-cut advantages. Colchicine specifically suppresses acute gouty arthritis. Its analogues, desacetylcolchicine and desacetylthiocolchicine, produce fewer unpleasant gastrointestinal symptoms, but may promote agranulocytosis and alopecia.A number of indole preparations with anti-inflammatory activity have been tested clinically. One of them, indomethacin, has received extensive

This study examines the anti-inflammatory effect of four honeys on wound healing, to gauge its efficacy as a treatment option. Isolated phenolics and crude extracts from manuka (Leptospermum scoparium, kanuka (Kunzea ericoides, clover (Trifolium spp., and a manuka/kanuka blend of honeys were examined. Anti-inflammatory assays were conducted in HEK-Blue™-2, HEK-Blue™-4, and nucleotide oligomerization domain (NOD2-Wild Type (NOD2-WT cell lines, to assess the extent to which honey treatment impacts on the inflammatory response and whether the effect was pathway-specific. Kanuka honey, and to a lesser extent manuka honey, produced a powerful anti-inflammatory effect related to their phenolic content. The effect was observed in HEK-Blue™-2 cells using the synthetic tripalmitoylated lipopeptide Pam3CysSerLys4 (Pam3CSK4 ligand, suggesting that honey acts specifically through the toll-like receptor (TLR1/TLR2 signaling pathway. The manuka/kanuka blend and clover honeys had no significant anti-inflammatory effect in any cell line. The research found that kanuka and manuka honeys have an important role in modulating the inflammatory response associated with wound healing, through a pathway-specific effect. The phenolic content of honey correlates with its effectiveness, although the specific compounds involved remain to be determined.

    Objective: To evaluate the anti-inflammatory, anticoagulant and antioxidant effects of aqueous extracts of thyme varieties from Moroccan.Methods: The aqueous extracts of tree medicinal plants [Thymus atlanticus(T. atlanticus), Thymus satureioides and Thymus zygis(T. zygis)] were screened for their antioxidant activity using 1,1-diphenyl-2-picrylhydrazyl radical-scavenging, ferric reducing antioxidant power assay, radical scavenging activity method, the inhibition of 2,2’-azobis(2-amidinopropane) dihydrochloride that induces oxidative erythrocyte hemolysis and thiobarbituric acid reactive substances assay. The anti-inflammatory activity of aqueous extracts was evaluated in vivo using croton oil-induced ear edema and carrageenan-induced paw edema in mice and rats, respectively. This extracts were evaluated in vitro for their anticoagulant activity at the different concentrations by partial thromboplastin time and prothrombin time activated. Results: All thyme varieties were found to possess considerable antioxidant activity and potent anti-inflammatory activity in the croton oil-induced edema. Administration of aqueous extracts of two varieties(50 mg/kg)(T. zygis and T. atlanticus) reduced significantly the carrageenaninduced paw edema similar to non-steroidal anti-inflammatory drug(indomethacin, 10 mg/kg). In partial thromboplastin time and prothrombin time tests, T. atlanticus and T. zygis extracts showed the strongest anticoagulant activity. In contrast, Thymus satureioides did not show the anticoagulant activity in these tests. Conclusions: All aqueous extracts possess considerable antioxidant activity and are rich in total polyphenol and flavonoid but they act differently in the process of inflammatory and coagulation studied. This study shows great variability of biological activities in thyme varieties.

These agents also possess broad-spectrum, secondary, anti-inflammatory properties. These are mediated largely, though not exclusively, via interactions with adenylyl cyclase-coupled β2-adrenoreceptors on a range of immune and inflammatory cells involved in the immunopathogenesis of acute and chronic inflammatory disorders of the airways. The clinical relevance of the anti-inflammatory actions of β2-agonists, although often effective in the experimental setting, remains contentious. The primary objectives of the current review are: firstly, to assess the mechanisms, both molecular and cell-associated, that may limit the anti-inflammatory efficacy of β2-agonists; secondly, to evaluate pharmacological strategies, several of which are recent and innovative, that may overcome these limitations. These are preceded by a consideration of the various types of β2-agonists, their clinical applications, and spectrum of anti-inflammatory activities, particularly those involving adenosine 3',5'-cyclic adenosine monophosphate-activated protein kinase-mediated clearance of cytosolic calcium, and altered gene expression in immune and inflammatory cells.

    The purpose of this investigation was to study the anti-inflammatory activities of both glycerrhitinic acid (GA) and the aqueous licorice extract (ALE) in comparison with diclofenac sodium (DS) (10 mg/kg), using the carrageenan-induced paw edema model in male albino rats. In addition, the anti-ulcer activities of ALE, famotidine (FT), and a combination of ALE and FT using indomethacin-induced ulceration technique in rat stomach were investigated. Conventional DS tablets containing GA, as well as DS chewable tablets containing either GA or ALE with different tastes were prepared. Also, rapidly disintegrating FT tablets were prepared using direct compression and camphor sublimation methods. ALE or GA produced significant anti-inflammatory activity similar to DS, and when taken concomitantly, there is no possible antagonism. The anti-ulcer activity of licorice was found to be similar to that of FT in indomethacin-induced ulceration technique in rat stomach. Combination therapy of both FT and licorice showed higher anti-ulcer activity than either of them alone. Generally, tablets containing the crosslinked sodium carboxymethyl cellulose (AcDisol) showed more rapidly disintegrating effect than those including Sodium starch glycolate (Primojel). The oral disintegration was very rapid for all the tested formulations. Also, the amount of FT absorbed from the oral cavity was nearly 9 from 10 mg theoretically present in each formula. It could be concluded that both GA and ALE have anti-inflammatory activity comparable with DS. It may be recommended to add ALE to either FT or diclofinac for more effective anti-inflammatory or anti-ulcer formulations, respectively.

    2012-07-01

    Full Text Available Macrophages and dendritic cells (DC share the same precursor and play key roles in immunity. Modulation of their behaviour to achieve an optimal host response towards an implanted device is still a challenge. Here we compare the differentiation process and polarisation of these related cell populations and show that they exhibit different responses to chitosan (Ch, with human monocyte-derived macrophages polarising towards an anti-inflammatory phenotype while their DC counterparts display pro-inflammatory features. Macrophages and DC, whose interactions with biomaterials are frequently analysed using fully differentiated cells, were cultured directly on Ch films, rather than exposed to the polymer after complete differentiation. Ch was the sole stimulating factor and activated both macrophages and DC, without leading to significant T cell proliferation. After 10 d on Ch, macrophages significantly down-regulated expression of pro-inflammatory markers, CD86 and MHCII. Production of pro-inflammatory cytokines, particularly TNF-α, decreased with time for cells cultured on Ch, while anti-inflammatory IL-10 and TGF-β1, significantly increased. Altogether, these results suggest an M2c polarisation. Also, macrophage matrix metalloproteinase activity was augmented and cell motility was stimulated by Ch. Conversely, DC significantly enhanced CD86 expression, reduced IL-10 secretion and increased TNF-α and IL-1β levels. Our findings indicate that cells with a common precursor may display different responses, when challenged by the same biomaterial. Moreover, they help to further comprehend macrophage/DC interactions with Ch and the balance between pro- and anti-inflammatory signals associated with implant biomaterials. We propose that an overall pro-inflammatory reaction may hide the expression of anti-inflammatory cytokines, likely relevant for tissue repair/regeneration.

  7. Neurostimulation of the cholinergic anti-inflammatory pathway ameliorates disease in rat collagen-induced arthritis.

    Directory of Open Access Journals (Sweden)

    Yaakov A Levine

    Full Text Available INTRODUCTION: The inflammatory reflex is a physiological mechanism through which the nervous system maintains immunologic homeostasis by modulating innate and adaptive immunity. We postulated that the reflex might be harnessed therapeutically to reduce pathological levels of inflammation in rheumatoid arthritis by activating its prototypical efferent arm, termed the cholinergic anti-inflammatory pathway. To explore this, we determined whether electrical neurostimulation of the cholinergic anti-inflammatory pathway reduced disease severity in the collagen-induced arthritis model. METHODS: Rats implanted with vagus nerve cuff electrodes had collagen-induced arthritis induced and were followed for 15 days. Animals underwent active or sham electrical stimulation once daily from day 9 through the conclusion of the study. Joint swelling, histology, and levels of cytokines and bone metabolism mediators were assessed. RESULTS: Compared with sham treatment, active neurostimulation of the cholinergic anti-inflammatory pathway resulted in a 52% reduction in ankle diameter (p = 0.02, a 57% reduction in ankle diameter (area under curve; p = 0.02 and 46% reduction overall histological arthritis score (p = 0.01 with significant improvements in inflammation, pannus formation, cartilage destruction, and bone erosion (p = 0.02, accompanied by numerical reductions in systemic cytokine levels, not reaching statistical significance. Bone erosion improvement was associated with a decrease in serum levels of receptor activator of NF-κB ligand (RANKL from 132±13 to 6±2 pg/mL (mean±SEM, p = 0.01. CONCLUSIONS: The severity of collagen-induced arthritis is reduced by neurostimulation of the cholinergic anti-inflammatory pathway delivered using an implanted electrical vagus nerve stimulation cuff electrode, and supports the rationale for testing this approach in human inflammatory disorders.

    Objective: To evaluate the anti-inflammatory effect of Nardostachys jatamansi (N. jatamansi) rhizome against acute, subacute and chronic models of inflammation in experimental animals.Methods: N. jatamansi rhizome extract (150 and 300 mg/kg, p.o.) and the reference drugs phenylbutazone (100 mg/kg, p.o.) and acetylsalicylic acid (300 mg/kg, p.o.) were evaluated using models for inflammation (autacoids induced hind paw oedema, formaldehyde induced hind paw oedema, carrageenin-induced paw oedema, cotton pellet granuloma and subcutaneous air pouch model). Results: In acute inflammation as produced by carrageenin 29.06% and 55.81%, by histamine 25.0% and 39.28%, by 5-hydroxytryptamine 21.37% and 36.95% and by prostaglandin E2-induced hind paw oedema 31.03% and 44.82% protection was observed. While in subacute anti-inflammatory models using formaldehyde-induced hind paw oedema (after 1.5 h) 13.88% and 33.33% and in chronic anti-inflammatory model using cotton pellet granuloma 7.4% and 17.58%protection from inflammation was observed. N. jatamansi rhizome extract also inhibited the inflammatory mediators (nitric oxide by 12.81% and 38.41%, by prostaglandin E2 12.58% and 47.82%while by TNF-α 13.51% and 41.89%) produced in the pouch. Conclusions: The results of this study strongly indicate the protective effect of N. jatamansi rhizome extract against acute, subacute and chronic models of inflammation, which may be attributed to its anti-inflammatory potential.

    In this study, the anti-inflammatory and anti-ulcerative effects of metyrosine, a selective tyrosine hydroxylase enzyme inhibitor, were investigated in rats. For ulcer experiments, indomethacin-induced gastric ulcer tests and ethanol-induced gastric ulcer tests were used. For these experiments, rats were fasted for 24 h. Different doses of metyrosine and 25 mg/kg doses of ranitidine were administered to rats, followed by indomethacin at 25 mg/kg for the indomethacin-induced ulcer test, or 50% ethanol for the ethanol-induced test. Results have shown that at all of the doses used (50, 100 and 200 mg/kg), metyrosine had significant anti-ulcerative effects in both indomethacin and ethanol-induced ulcer tests. Metyrosine doses of 100 and 200 mg/kg (especially the 200 mg/kg dose) also inhibited carrageenan-induced paw inflammation even more effectively than indomethacin. In addition, to characterize the anti-inflammatory mechanism of metyrosine we investigated its effects on cyclooxygenase (COX) activity in inflammatory tissue (rat paw). The results showed that all doses of metyrosine significantly inhibited high COX-2 activity. The degree of COX-2 inhibition correlated with the increase in anti-inflammatory activity. In conclusion, we found that metyrosine has more anti-inflammatory effects than indomethacin and that these effects can be attributed to the selective inhibition of COX-2 enzymes by metyrosine. We also found that adrenalin levels are reduced upon metyrosine treatment, which may be the cause of the observed gastro-protective effects of this compound.

    The cytokine erythropoietin (EPO) stimulates proliferation and differentiation of erythroid progenitor cells. Moreover, EPO has neuroprotective, anti-inflammatory, and antioxidative effects, but the use of EPO as a neuroprotective agent is hampered by its erythropoietic activity. We have recently...... designed the synthetic, dendrimeric peptide, Epobis, derived from the sequence of human EPO. This peptide binds the EPO receptor and promotes neuritogenesis and neuronal cell survival. Here we demonstrate that Epobis in vitro promotes neuritogenesis in primary motoneurons and has anti-inflammatory effects....... These data reveal Epobis to be a nonerythropoietic and neuroprotective EPO receptor agonist with anti-inflammatory and memory enhancing properties....

    Fucan is a term that defines a family of homo- and hetero-polysaccharides containing sulfated l-fucose in its structure. In this work, a heterofucan (F2.0v) from the seaweed, Dictyota menstrualis, was evaluated as an antinociceptive and anti-inflammatory agent. F2.0v (20.0 mg/kg) inhibits 100% of leukocyte migration into the peritoneal cavity after chemical stimulation. However, F2.0v does not alter the expression of interleukin-1 beta (IL-1β) and interleukin-6 (IL-6), as well as tumor necrosis factor alpha (TNF-α). F2.0v (20.0 mg/kg) has peripheral antinociceptive activity with potency similar to dipyrone. On the other hand, it had no effect on pain response on the hot plate test. Confocal microscopy analysis and flow cytometry showed that F2.0v binds to the surface of leucocytes, which leads us to suggest that the mechanism of action of anti-inflammatory and antinociceptive F2.0v is related to its ability to inhibit the migration of leukocytes to the site of tissue injury. In summary, the data show that F2.0v compound has great potential as an antinociceptive and anti-inflammatory, and future studies will be performed to further characterize the mechanism of action of F2.0v.

    Echinacea purpurea L. is a medicinal plant originally from North America. It has become a commonly used herbal medicine worldwide because it contains various biologically active compounds. This study was designed to investigate the anti-inflammatory effects of essential oils from E. purpurea in both mice and rats. The extract was obtained from flower of E. purpurea by steam distillation. The anti-inflammatory potential was evaluated in vivo by using different animal models such as xylene-induced mouse ear edema, egg-white-induced rat paw edema, and cotton-induced granuloma tissue proliferating inflammation in mice. The serial dosages were used in vivo: the low dosage, the medium dosage and the high dosage. The low, medium and high dosages of extracts produced inhibitions of 39.24%, 47.22% and 44.79% respectively in the ear edema induced by xylene when compare with the control group. Only the high dosage group showed statistically significant inhibition (48.51%) of paw edema formation induced three hours by egg white compared with the control group (Pessential oils from extracts of E. purpurea have anti-inflammatory effects.

    Full Text Available With a number of common therapeutic prescriptions, common mechanisms, common pharmacological effects - analgesic, antipyretic and anti-inflammatory (acetaminophen excepted, common side effects (SE (platelet dysfunction, gastritis and peptic ulcers, renal insufficiency in susceptible patients, water and sodium retention, edemas, nephropathies, and only a few different characteristics – different chemical structures, pharmacokinetics and different therapeutic possibility, different selectivities according to cyclooxygenase pathway 1 and 2, non-steroidal anti-inflammatory drugs (NSAIDs similarities are more apparent than differences. Being known that in a correct treatment benefits would exceed risks, the question “Which anti-inflammatory drug presents the lowest risks for a patient?” is just natural. By the Global Risk Method (GRM and the Maximum Risk Method (MRM we have determined the ranking of fourteen NSAIDs considering the risks presented by each particular NSAID. Nimesulide, Etoricoxib and Celecoxib safety level came superior to the other NSAIDs, whereas Etodolac and Indomethacin present an increased side effects risk.

    Full Text Available Inflammation is the major causative factor of different diseases such as cardiovascular disease, diabetes, obesity, osteoporosis, rheumatoid arthritis, inflammatory bowel disease, and cancer. Anti-inflammatory drugs are often the first step of treatment in many of these diseases. The present study is aimed at evaluating the anti-inflammatory properties of isoorientin, a selective cyclooxygenase-2 (COX-2 inhibitor isolated from the tubers of Pueraria tuberosa, in vitro on mouse macrophage cell line (RAW 264.7 and in vivo on mouse paw edema and air pouch models of inflammation. Isoorientin reduced inflammation in RAW 264.7 cell line in vitro and carrageenan induced inflammatory animal model systems in vivo. Cellular infiltration into pouch tissue was reduced in isoorientin treated mice compared to carrageenan treated mice. Isoorientin treated RAW 264.7 cells and animals showed reduced expression of inflammatory proteins like COX-2, tumor necrosis factor-α (TNF-α, interleukin-6 (IL-6, 5-lipoxygenase (5-LOX, and interleukin 1-β (IL-1-β both in vitro and in vivo. The antioxidant enzyme levels of catalase and GST were markedly increased in isoorientin treated mice compared to carrageenan treated mice. These results suggest that isoorientin, a selective inhibitor of COX-2, not only exerts anti-inflammatory effects in LPS induced RAW cells and carrageenan induced inflammatory model systems but also exhibits potent antioxidant properties.

    Jojoba [Simmondsia chinensis (Link 1822) Schneider 1907] is an arid perennial shrub grown in several American and African countries. Jojoba seeds, which are rich in liquid wax, were used in folk medicine for diverse ailments. In the current study, the potential anti-inflammatory activity of jojoba liquid wax (JLW) was evaluated in a number of experimental models. Results showed that JLW caused reduction of carrageenin-induced rat paw oedema in addition to diminishing prostaglandin E2 (PGE2) level in the inflammatory exudates. In a test for anti-inflammatory potential utilizing the chick's embryo chroioallantoic membrane (CAM), JLW also caused significant lowering of granulation tissue formation. Topical application of JLW reduced ear oedema induced by croton oil in rats. In the same animal model, JLW also reduced neutrophil infiltration, as indicated by decreased myeloperoxidase (MPO) activity. In addition, JLW ameliorated histopathological changes affected by croton oil application. In the lipopolysaccharide (LPS)-induced inflammation in air pouch in rats, JLW reduced nitric oxide (NO) level and tumor necrosis factor-alpha (TNF-alpha) release. In conclusion, this study demonstrates the effectiveness of JLW in combating inflammation in several experimental models. Further investigations are needed to identify the active constituents responsible for the anti-inflammatory property of JLW.

    Full Text Available In our continuing interest on Sarawak Garcinia species, we carried out the evaluation of antioxidant, anti-inflammatory and cytotoxic activities on the methanolic extracts of Garcinia nervosa. The extracts were prepared from its air-dried grounded leaves and barks. The evaluation of antioxidant activities was done using the (2,2-diphenyl-1-picrylhydrazyl DPPH radical scavenging assay and the result showed high radical scavenging activities. Meanwhile, the anti-inflammatory evaluation was performed using the lipoxygenase assay, hyaluronidase assay, and xanthine oxidase assay which showed, both of these extracts exhibited high anti-inflammatory properties. The lipoxygenase assay showed a high inhibition of enzyme activity for the barks extracts and a moderate enzyme activity for the leaves extracts. However, there were low inhibitions for both extracts in the hyaluronidase assay and only the barks extracts exhibited moderate antigout properties in the xanthine oxidase assay. For the cytotoxic assay, the extracts exhibited positive responses against the three cancer cell lines, the HeLa cell lines, MCF-7 cell lines, and HT-29 cell lines. Thus, Garcinia nervosa contains high antioxidativeand anti-inflammation properties, which have great potential in the development of pharmaceutical and dermatological products.

    Castilleja tenuiflora (Orobanchaceae) has been used in Mexican traditional medicine as a treatment for cough, dysentery, anxiety, nausea and vomiting as well as hepatic and gastrointestinal diseases. The ethanolic extract of the aerial parts of Castilleja tenuiflora was separated by silica gel column chromatography. The fractions were evaluated using the induced edema acetate 12-O-tetradecanoylphorbol (TPA) anti-inflammatory activity model. The most active fraction was subjected to medium-pressure liquid chromatography (MPLC) with UV detection at 206 and 240 nm. The following iridoids were isolated: geniposidic acid, aucubin, bartioside, 8-epi-loganin, mussaenoside, and the phenylpropanoid verbascoside. The most active iridoid was geniposidic acid, which was more active than the control (indomethacin), and the least active iridoid was mussaenoside. 8-epi-Loganin, and mussaenoside have not been previously reported to be anti-inflammatory compounds. The results of these investigations confirm the potential of Mexican plants for the production of bioactive compounds and validate the ethnomedical use of Castilleja tenuiflora-like anti-inflammatory plants.

    Pebisut is a biological adhesive composed of naturally occurring carbohydrates combined with zinc oxide (ZnO) initially used as a coadjutant for healing of anastomoses. Likewise some works demonstrated that carbohydrate complexes exerts anti-inflammatory activity and it is widely known that ZnO modulate inflammation. However, the direct effects of Pebisut on isolated cells and acute inflammatory responses remained to be investigated. The present study evaluated anti-inflammatory effect of Pebisut using lipopolysaccharide (LPS) stimulated human mononuclear cells, chemotaxis, and cell infiltration in vivo in a murine model of peritonitis. Our data show that human cells treated with different dilutions of Pebisut release less IL-6, IL-1β, and IL-8 after LPS stimuli compared with the control treated cells. In addition, Pebisut lacked chemotactic activity in human mononuclear cells but was able to reduce chemotaxis towards CCL2, CCL5, and CXCL12 that are representative mononuclear cells chemoattractants. Finally, in a murine model of peritonitis, we found less number of macrophages (F4/80+) and T lymphocytes (CD3+) in peritoneal lavages from animals treated with Pebisut. Our results suggest that Pebisut has anti-inflammatory activity, which might have a beneficial effect during anastomoses healing or wounds associated with excessive inflammation. PMID:24757670

    Full Text Available Propolis is a complex resinous substance manufactured by honey bees to scaffold and protect the hive against pathogens. Although it has been widely used for its medicinal properties, it is unknown whether the activity depends on the concentrations of specific constituents or on potentiation between these. This study describes (1 the individual topical anti-inflammatory activities of selected flavonoids commonly found in propolis, and (2 their antibacterial activities, alone or in combination with the non-flavonoid caffeic acid phenethyl ester (CAPE. For the anti-inflammatory activities, the reduction in croton oil-induced oedema in a mouse model, after topical application of quercetin and galangin for 3 h, was more than 50%, while after 6 h of treatment the reduction was less then 50%. By contrast, the suppressive activity of luteolin was about 30% and 50%, for treatments of 3 h and 6 h, respectively. The maximum inhibition of the growth of Staphylococcus aureus by each of CAPE, eriodictyol and quercetin was about 20%, while luteolin was inactive. When combined with CAPE, potentiation of the antibacterial effect was observed in the case of luteolin, but antagonism was observed when combined with either eriodictyol or quercetin. The propolis flavonoids each appear to have significant anti-inflammatory activity while their antibacterial activities are somewhat weaker and significant only when luteolin was combined with CAPE.

    Tea tree oil (TTO) is well known as an antimicrobial and immunomodulatory agent. In the present study we confirmed the anti-inflammatory properties of TTO and investigated the involvement of the hypothalamic-pituitary-adrenal (HPA) axis in the immunomodulatory action of TTO administered by inhalation. Sexually mature, 6-8-week-old, C(57)BI(10) x CBA/H (F(1)) male mice were used. One group of animals was injected intra-peritoneally (ip) with Zymosan to elicit peritoneal inflammation and was then submitted to four sessions of TTO inhalation (15 mins each). Some of the mice were simultaneously injected ip with Antalarmin, a CRH-1 receptor antagonist, to block HPA axis functions. Twenty-four hours after the injections the mice were killed by CO(2) asphyxia, and peritoneal leukocytes (PTLs) were isolated and counted. Levels of reactive oxygen species (ROS) and cyclooxygenase (COX) activity in PTLs were assessed by fluorimetric and colorimetric assays, respectively. The results obtained show that sessions of TTO inhalation exert a strong anti-inflammatory influence on the immune system stimulated by Zymosan injection, while having no influence on PTL number, ROS level, and COX activity in mice without inflammation. The HPA axis was shown to mediate the anti-inflammatory effect of TTO; Antalarmin abolished the influence of inhaled TTO on PTL number and their ROS production in mice with experimental peritonitis, but it had no effect on these parameters in mice without inflammation.

    We previously demonstrated that the organic extract of Spirulina platensis (SPE), an edible blue-green alga, possesses potent anti-inflammatory effects. In this study, we investigated if the regulation of histone deacetylases (HDACs) play a role in the anti-inflammatory effect of SPE in macrophages. Treatment of macrophages with SPE rapidly and dose-dependently reduced HDAC2, 3, and 4 proteins which preceded decreases in their mRNA levels. Degradation of HDAC4 protein was attenuated in the presence of inhibitors of calpain proteases, lysosomal acidification, and Ca(2+)/calmodulin-dependent protein kinase II, respectively, but not a proteasome inhibitor. Acetylated histone H3 was increased in SPE-treated macrophages to a similar level as macrophages treated with a pan-HDAC inhibitor, with concomitant inhibition of inflammatory gene expression upon LPS stimulation. Knockdown of HDAC3 increased basal and LPS-induced pro-inflammatory gene expression, while HDAC4 knockdown increased basal expression of interleukin-1β (IL-1β), but attenuated LPS-induced inflammatory gene expression. Chromatin immunoprecipitation showed that SPE decreased p65 binding and H3K9/K14 acetylation at the Il-1β and tumor necrosis factor α (Tnfα) promoters. Our results suggest that SPE increased global histone H3 acetylation by facilitating HDAC protein degradation, but decreases histone H3K9/K14 acetylation and p65 binding at the promoters of Il-1β and Tnfα to exert its anti-inflammatory effect.

    2012-01-01

    Full Text Available This study investigated possible analgesic and anti-inflammatory mechanisms of the methanol extract of Ficus pumila (FPMeOH. Analgesic effects were evaluated in two models including acetic acid-induced writhing response and formalin-induced paw licking. The results showed FPMeOH decreased writhing response in the acetic acid assay and licking time in the formalin test. The anti-inflammatory effect was evaluated by λ-carrageenan-induced mouse paw edema and histopathological analyses. FPMeOH significantly decreased the volume of paw edema induced by λ-carrageenan. Histopathologically, FPMeOH abated the level of tissue destruction and swelling of the edema paws. This study indicated anti-inflammatory mechanism of FPMeOH may be due to declined levels of NO and MDA in the edema paw through increasing the activities of SOD, GPx, and GRd in the liver. Additionally, FPMeOH also decreased the level of inflammatory mediators such as IL-1β, TNF-α, and COX-2. HPLC fingerprint was established and the contents of three active ingredients, rutin, luteolin, and apigenin, were quantitatively determined. This study provided evidence for the classical treatment of Ficus pumila in inflammatory diseases.

    Decoctions prepared from the bark of Uncaria tomentosa (cat's claw) are widely used in the traditional Peruvian medicine for the treatment of several diseases, in particular as a potent anti-inflammatory agent. Therefore, the main purpose of this study was to determine if the well-known anti-inflammatory activity of cat's claw decoction was related with its reactivity with the oxidant species generated in the inflammatory process and to establish a relationship between such antioxidant ability and its phenolic composition. We observed that the decoction prepared according to the traditional Peruvian medicine presented a potent radical scavenger activity, as suggested by its high capacity to reduce the free radical diphenylpicrylhydrazyl, and by its reaction with superoxide anion, peroxyl and hydroxyl radicals as well as with the oxidant species, hydrogen peroxide and hypochlorous acid. It also protected membrane lipids against peroxidation induced by the iron/ascorbate system, as evaluated by the formation of thiobarbituric acid-reactive substances (TBARs). The decoction phenolic profile was established by chromatographic analysis (HPLC/DAD and TLC) revealing essentially the presence of proanthocyanidins (oligomeric procyanidins) and phenolic acids, mainly caffeic acid. Thus, our results provide evidence for an antioxidant mechanism underlying the anti-inflammatory activity of cat's claw and support some of the biological effects of proanthocyanidins, more exactly its antioxidant and radical scavenging activities.

    2012-12-01

    Full Text Available The design and the synthesis of prodrugs for nonsteroidal anti-inflammatory drugs (NSAIDs have been given much attention by medicinal chemists, especially in the last decade. As a therapeutic group, NSAIDs are among the most widely used prescribed and over the counter (OTC medications. The rich literature about potential NSAID prodrugs clearly shows a shift from alkyl, aryalkyl or aryl esters with the sole role of masking the carboxylic acid group, to more elaborate conjugates that contain carefully chosen groups to serve specific purposes, such as enhancement of water solubility and dissolution, nitric oxide release, hydrogen sulfide release, antioxidant activity, anticholinergic and acetylcholinesterase inhibitory (AChEI activity and site-specific targeting and delivery. This review will focus on NSAID prodrugs that have been designed or were, later, found to possess intrinsic pharmacological activity as an intact chemical entity. Such intrinsic activity might augment the anti-inflammatory activity of the NSAID, reduce its side effects or transform the potential therapeutic use from classical anti-inflammatory action to something else. Reports discussed in this review will be those of NO-NSAIDs, anticholinergic and AChEI-NSAIDs, Phospho-NSAIDs and some miscellaneous agents. In most cases, this review will cover literature dealing with these NSAID prodrugs from the year 2006 and later. Older literature will be used when necessary, e.g., to explain the chemical and biological mechanisms of action.

In this study, two highly lipophilic fractions AFLF and ACLF isolated from A. floribunda and A. cordifolia leaves respectively were investigated for topical anti-inflammatory effects using xylene-induced mice ear oedema as a model of inflammation. AFLF and ACLF at 5 mg per ear showed significant (p eugenol (21.26%) and cadinol (4.76%), and other constituents like, nanocosaine (36.86%) and steroid derivatives, ethyl iso-allocholate (4.59%) and 3-acetoxy-7,8-epoxylanostan-1-ol (15.86%). Analysis of the volatile oil (ACV) extracted from the fresh leaves of A. cordifolia revealed the presence of high concentrations of eugenol (41.7%), cadinol (2.46%), Caryophylene (1.04%), Linalool (30.59%) and (E)-α-bergamotene (4.54%). These compounds could be contributing to the topical anti-inflammatory effects of A. floribunda and A. cordifolia leaf extracts.

    Cordyceps bassiana is one of Cordyceps species with anti-oxidative, anti-cancer, anti-inflammatory, anti-diabetic, anti-obesity, anti-angiogenic, and anti-nociceptive activities. This mushroom has recently demonstrated to have an ability to reduce 2,4-dinitrofluorobenzene-induced atopic dermatitis symptoms in NC/Nga mice. In this study, we further examined phytochemical properties of this mushroom by column chromatography and HPLC analysis. By chromatographic separation and spectroscopic analysis, 8 compounds, such as 1,9-dimethylguanine (1), adenosine (2), uridine (3), nicotinamide (4), 3-methyluracil (5), 1,7-dimethylxanthine (6), nudifloric acid (7), and mannitol (8) were identified from 6 different fractions and 4 more subfractions. Through evaluation of their anti-inflammatory activities using reporter gene assay and mRNA analysis, compound 1 was found to block luciferase activity induced by NF-κB and AP-1, suppress the mRNA levels of cyclooxygenase (COX)-2 and tumor necrosis factor (TNF)-α. Therefore, our data strongly suggests that compound 1 acts as one of major principles in Cordyceps bassiana with anti-inflammatory and anti-atopic dermatitis activities.

    Ortho-eugenol is a much used phenylpropanoid whose ability to reduce pain and inflammation has never been studied. Researching ortho-eugenol's antinociceptive and anti-inflammatory activity, and its possible mechanisms of action is therefore of interest. The administration of vehicle, ortho-eugenol (50, 75 and 100mg/kg i.p.), morphine (6mg/kg, i.p.) or dexamethasone (2mg/kg, s.c.) occurred 30min before the completion of pharmacological tests. Pretreatment with ortho-eugenol did not change motor coordination test results, but reduced the number of writhes and licking times in the writhing test and glutamate test, respectively. The reaction time from thermal stimulus was significantly increased in the hot plate test after administration of ortho-eugenol. Treatment with yohimbine reversed the antinociceptive effect of ortho-eugenol, suggesting involvement of the adrenergic system. In anti-inflammatory tests, ortho-eugenol inhibited acetic acid induced vascular permeability and leukocyte migration, reducing TNF-α and IL-1β by virtue of its suppression of NF-κB and p38 phosphorylated forms in the peritonitis test. From these results, ortho-eugenol antinociceptive effects mediated by the adrenergic system and anti-inflammatory activity through regulation of proinflammatory cytokines and phosphorylation of NF-kB and p38 become evident for the first time.

    Species of the agave genus, such as Agave tequilana, Agave angustifolia and Agave americana are used in Mexican traditional medicine to treat inflammation-associated conditions. These plants' leaves contain saponin compounds which show anti-inflammatory properties in different models. The goal of this investigation was to evaluate the anti-inflammatory capacity of these plants, identify which is the most active, and isolate the active compound by a bio-directed fractionation using the ear edema induced in mice with 12-O-tetradecanoylphorbol-13-acetate (TPA) technique. A dose of 6 mg/ear of acetone extract from the three agave species induced anti-inflammatory effects, however, the one from A. americana proved to be the most active. Different fractions of this species showed biological activity. Finally the F5 fraction at 2.0 mg/ear induced an inhibition of 85.6%. We identified one compound in this fraction as (25R)-5α-spirostan-3β,6α,23α-triol-3,6-di-O-β-D-glucopyranoside (cantalasaponin-1) through 1H- and 13C-NMR spectral analysis and two dimensional experiments like DEPT NMR, COSY, HSQC and HMBC. This steroidal glycoside showed a dose dependent effect of up to 90% of ear edema inhibition at the highest dose of 1.5 mg/ear.

    Full Text Available Oxidative damage and inflammation have been pointed out in preclinical studies as the root cause of cancer and other chronic diseases such as diabetes, hypertension, Alzheimer’s disease, etc. Epidemiological and clinical studies have suggested that cancer could be prevented or significantly reduced by treatment with anti-oxidant and anti-inflammatory drugs, therefore, curcumin, a principal component of turmeric (a curry spice showing strong anti-oxidant and anti-inflammatory activities, might be a potential candidate for the prevention and/or treatment of cancer and other chronic diseases. However, curcumin, a highly pleiotropic molecule with an excellent safety profile targeting multiple diseases with strong evidence on the molecular level, could not achieve its optimum therapeutic outcome in past clinical trials, largely due to its low solubility and poor bioavailability. Curcumin can be developed as a therapeutic drug through improvement in formulation properties or delivery systems, enabling its enhanced absorption and cellular uptake. This review mainly focuses on the anti-inflammatory potential of curcumin and recent developments in dosage form and nanoparticulate delivery systems with the possibilities of therapeutic application of curcumin for the prevention and/or treatment of cancer.

    Full Text Available NSAIDs are frequently used for relief of inflammati on and Antihistaminics are indicated for simultaneous administration for aller gic manifestations. Opioids analgesics have been reported to interact with Antihistaminics. To e xplore the interacting potentiality, in the present study the effects of combined treatment with NSAIDs and antihistaminics were examined in rats. Anti-inflammatory effect was eval uated by Carrageenan induced hind paw oedema in rats. NSAIDs like aspirin, ibuprofen and pir oxicam were selected for study on per se and on concurrent administration with Antihistamini cs such as Promethazine, Cetrizine and Astemizole. All NSAIDs protected animals show anti-i nflammatory activity. Aspirin shows highly significant potentiation of anti-inflammatory effect at all dose level, however ibuprofen and piroxicam show highly significant anti-inflammatory effect at higher doses only and on concurrent administration of antihistaminics, aspiri n, piroxicam and ibuprofen with all antihistaminics produced highly significant potentiat ion except ibuprofen with Cetrizine produced significant potentiation of anti-inflammator y response at higher doses only.

    Corticosteroids have previously been found to be protective against the mortality of radiation pneumonitis in mice, even when given well after lethal lung irradiation. The authors explored the possibility that this effect was due to their well-known anti-inflammatory actions by giving various nonsteroidal inhibitors of arachidonate metabolism to groups of mice that had received 19 Gy to the thorax (bilaterally). Treatments of four cyclooxygenase inhibitors, one lipoxygenase inhibitor, and one leukotriene receptor antagonist, given by various routes in various doses, were commenced 10 weeks after irradiation or sham irradiation and continued throughout the period when death from radiation pneumonitis occurs, 11-26 weeks after irradiation. Each of the treatments had the appropriate effect on arachidonate metabolism in the lungs as assessed by LTB4 and PGE2 levels in lung lavage fluid. The principal end point was mortality. The 5-lipoxygenase inhibitor diethylcarbamazine and the LTD4/LTE4 receptor antagonist LY 171883 markedly reduced mortality in dose-response fashion. The effects of cyclooxygenase inhibitors were divergent; piroxicam and ibuprofen were marginally protective, indomethacin in all doses accelerated mortality, and aspirin reduced mortality in a dose-response fashion. These results suggest that the protective effect of corticosteroids in radiation pneumonitis can be tentatively attributed to their anti-inflammatory actions, and that nonsteroidal anti-inflammatory agents, particularly those that affect lipoxygenase products, may offer equal or better protection than corticosteroids against mortality due to radiation pneumonitis.

    Full Text Available Castilleja tenuiflora (Orobanchaceae has been used in Mexican traditional medicine as a treatment for cough, dysentery, anxiety, nausea and vomiting as well as hepatic and gastrointestinal diseases. The ethanolic extract of the aerial parts of Castilleja tenuiflora was separated by silica gel column chromatography. The fractions were evaluated using the induced edema acetate 12-O-tetradecanoylphorbol (TPA anti-inflammatory activity model. The most active fraction was subjected to medium-pressure liquid chromatography (MPLC with UV detection at 206 and 240 nm. The following iridoids were isolated: geniposidic acid, aucubin, bartioside, 8-epi-loganin, mussaenoside, and the phenylpropanoid verbascoside. The most active iridoid was geniposidic acid, which was more active than the control (indomethacin, and the least active iridoid was mussaenoside. 8-epi-Loganin, and mussaenoside have not been previously reported to be anti-inflammatory compounds. The results of these investigations confirm the potential of Mexican plants for the production of bioactive compounds and validate the ethnomedical use of Castilleja tenuiflora-like anti-inflammatory plants.

    Fisetin is an anti-inflammatory flavonoid; however, its anti-inflammatory mechanism is not yet understood. In this study, we evaluated the anti-inflammatory effect of fisetin and its association with mitogen-activated protein kinase (MAPK) and nuclear factor kappa-beta pathways in human gingival fibroblasts (HGFs) treated with lipopolysaccharide (LPS) obtained from Porphyromonas gingivalis. The cell signaling, cell viability, and cyclooxygenase-2 (COX-2) expression of HGFs treated with various concentrations (0, 1, 5, 10, and 15 μM) of fisetin were measured by cell viability assay (MTT), Western blotting, and reverse transcriptase polymerase chain reaction analysis on COX-2. We found that fisetin significantly reduced the synthesis and expression of prostaglandin E2 in HGFs treated with LPS. Activation of extracellular signal-regulated kinase, c-Jun N-terminal kinase, and p38 MAPK was suppressed consistently by fisetin in HGFs treated with LPS. The data indicate that fisetin inhibits MAPK activation and COX-2 expression without affecting cell viability. These findings may be valuable for understanding the mechanism of the effect of fisetin on periodontal disease.

    The objective of this study was to evaluate the pharmacological mechanisms involved in anti-inflammatory and antidiarrheal actions of hydroalcoholic extract obtained from the leaves of Cissus sicyoides (HECS). The anti-inflammatory effect was evaluated by oral administration of HECS against acute model of edema induced by xylene, and the mechanisms of action were analysed by involvement of arachidonic acid (AA) and prostaglandin E2 (PGE2). The antidiarrheal effect of HECS was observed and we analyzed the motility and accumulation of intestinal fluid. We also analyzed the antidiarrheal mechanisms of action of HECS by evaluating the role of the opioid receptor, α2 adrenergic receptor, muscarinic receptor, nitric oxide (NO) and PGE2. The oral administration of HECS inhibited the edema induced by xylene and AA and was also able to significantly decrease the levels of PGE2. The extract also exhibited significant anti-diarrheal activity by reducing motility and intestinal fluid accumulation. This extract significantly reduced intestinal transit stimulated by muscarinic agonist and intestinal secretion induced by PGE2. Our data demonstrate that the mechanism of action involved in the anti-inflammatory effect of HECS is related to PGE2. The antidiarrheal effect of this extract may be mediated by inhibition of contraction by acting on the intestinal smooth muscle and/or intestinal transit. PMID:26805827

    Highlights: • Asparagine plays an important role to anti-inflammatory effect of peptides. • The electron-donor substituent groups favor the formation of the hydrogen bonds, which contribute in the structural stability of peptides. • Chemical reactivity and the physicochemical features are crucial in the biological functions of peptides. - Abstract: Inflammatory response events are initiated by a complex series of molecular reactions that generate chemical intermediaries. The structure and properties of peptides and proteins are determined by the charge distribution of their side chains, which play an essential role in its electronic structure and physicochemical properties, hence on its biological functionality. The aim of this study was to analyze the effect of changing one central amino acid, such as substituting asparagine for aspartic acid, from Cys–Asn–Ser in aqueous solution, by assessing the conformational stability, physicochemical properties, chemical reactivity and their relationship with anti-inflammatory activity; employing quantum-chemical descriptors at the M06-2X/6-311+G(d,p) level. Our results suggest that asparagine plays a more critical role than aspartic acid in the structural stability, physicochemical features, and chemical reactivity of these tripeptides. Substituent groups in the side chain cause significant changes on the conformational stability and chemical reactivity, and consequently on their anti-inflammatory activity.

Clove is used in cooking, food processing, pharmacy; perfumery, cosmetics and the clove oil (eugenol have been used in folk medicine for manifold conditions include use in dental care, as an antiseptic and analgesic. The objective of this study was evaluated the anti-inflammatory and antinociceptive activity of eugenol used for dentistry purposes following oral administration in animal models in vivo. The anti-inflammatory activity of eugenol was evaluated by inflammatory exudates volume and leukocytes migration in carrageenan-induced pleurisy and carrageenan-induced paw edema tests in rats. The antinociceptive activity was evaluated using the acetic acid-induced writhing and hot-plate tests in mice. Eugenol (200 and 400 mg/kg reduced the volume of pleural exudates without changing the total blood leukocyte counts. At dose of 200 mg/kg, eugenol significantly inhibited carrageenan-induced edema, 2-4 h after injection of the flogistic agent. In the hot-plate test, eugenol administration (100 mg/kg showed unremarkable activity against the time-to-discomfort reaction, recorded as response latency, which is blocked by meperidine. Eugenol at doses of 50, 75 and 100 mg/kg had a significant antinociceptive effect in the test of acetic-acid-induced abdominal writhing, compared to the control animals. The data suggest that eugenol possesses anti-inflammatory and peripheral antinociceptive activities.

    Non-steroidal anti-inflammatory drugs (NSAIDs) have been widely used for the modulation of the inflammatory response. However, a number of facts involving the occurrence of gastrointestinal lesions have limited the chronic use of NSAIDs. In order to diminish the occurrence of gastrointestinal damage caused by NSAIDs, the combination of NSAIDs with the H2 receptor blocker, cimetidine, has been evaluated. The anti-inflammatory and ulcerogenic effects of indomethacin and tenoxicam in association with or without cimetidine were determined at pre-clinical levels. It was observed that the group of animals treated with indomethacin and cimetidine, or tenoxicam and cimetidine (10 mg/kg, p.o.) demonstrated a significant reduction (P < 0.05, ANOVA followed by Tukey-Kramer multiple comparison test) of type-III gastric ulcers. Furthermore, indomethacin or tenoxicam (10 mg/kg, p.o.) in association with cimetidine increased the anti-inflammatory activity. The group, which received indomethacin and cimetidine presented the best performance in decreasing the inflammatory process (P < 0.05, ANOVA followed by Tukey-Kramer multiple comparison test).

    Objective. Infection, inflammation, and neuronal loss are common issues that seriously affect the functionality and longevity of chronically implanted neural prostheses. Minocycline hydrochloride (MH) is a broad-spectrum antibiotic and effective anti-inflammatory drug that also exhibits potent neuroprotective activities. In this study, we investigated the development of biocompatible thin film coatings capable of sustained release of MH for improving the long term performance of implanted neural electrodes. Approach. We developed a novel magnesium binding-mediated drug delivery mechanism for controlled and sustained release of MH from an ultrathin hydrophilic layer-by-layer (LbL) coating and characterized the parameters that control MH loading and release. The anti-biofilm, anti-inflammatory and neuroprotective potencies of the LbL coating and released MH were also examined. Main results. Sustained release of physiologically relevant amount of MH for 46 days was achieved from the Mg2+-based LbL coating at a thickness of 1.25 μm. In addition, MH release from the LbL coating is pH-sensitive. The coating and released MH demonstrated strong anti-biofilm, anti-inflammatory, and neuroprotective potencies. Significance. This study reports, for the first time, the development of a bioactive coating that can target infection, inflammation, and neuroprotection simultaneously, which may facilitate the translation of neural interfaces to clinical applications.

    Full Text Available Fucan is a term that defines a family of homo- and hetero-polysaccharides containing sulfated l-fucose in its structure. In this work, a heterofucan (F2.0v from the seaweed, Dictyota menstrualis, was evaluated as an antinociceptive and anti-inflammatory agent. F2.0v (20.0 mg/kg inhibits 100% of leukocyte migration into the peritoneal cavity after chemical stimulation. However, F2.0v does not alter the expression of interleukin-1 beta (IL-1β and interleukin-6 (IL-6, as well as tumor necrosis factor alpha (TNF-α. F2.0v (20.0 mg/kg has peripheral antinociceptive activity with potency similar to dipyrone. On the other hand, it had no effect on pain response on the hot plate test. Confocal microscopy analysis and flow cytometry showed that F2.0v binds to the surface of leucocytes, which leads us to suggest that the mechanism of action of anti-inflammatory and antinociceptive F2.0v is related to its ability to inhibit the migration of leukocytes to the site of tissue injury. In summary, the data show that F2.0v compound has great potential as an antinociceptive and anti-inflammatory, and future studies will be performed to further characterize the mechanism of action of F2.0v.

    Persistent systemic inflammation, a typical feature of inflammatory rheumatic diseases, is associated with a high cardiovascular risk and predisposes to metabolic disorders and muscle wasting. These disorders can lead to disability and decreased physical activity, exacerbating inflammation and the development of a network of chronic diseases, thus establishing a 'vicious cycle' of chronic inflammation. During the past two decades, advances in research have shed light on the role of exercise as a therapy for rheumatic diseases. One of the most important of these advances is the discovery that skeletal muscle communicates with other organs by secreting proteins called myokines. Some myokines are thought to induce anti-inflammatory responses with each bout of exercise and mediate long-term exercise-induced improvements in cardiovascular risk factors, having an indirect anti-inflammatory effect. Therefore, contrary to fears that physical activity might aggravate inflammatory pathways, exercise is now believed to be a potential treatment for patients with rheumatic diseases. In this Review, we discuss how exercise disrupts the vicious cycle of chronic inflammation directly, after each bout of exercise, and indirectly, by improving comorbidities and cardiovascular risk factors. We also discuss the mechanisms by which some myokines have anti-inflammatory functions in inflammatory rheumatic diseases.

    Duchenne muscular dystrophy (DMD), an incurable and a progressive muscle wasting disease, is caused by the absence of dystrophin protein, leading to recurrent muscle fiber damage during contraction. The inflammatory response to fiber damage is a compelling candidate mechanism for disease exacerbation. The only established pharmacological treatment for DMD is corticosteroids to suppress muscle inflammation, however this treatment is limited by its insufficient therapeutic efficacy and considerable side effects. Recent reports show the therapeutic potential of inhibiting or enhancing pro- or anti-inflammatory factors released from DMD skeletal muscles, resulting in significant recovery from muscle atrophy and dysfunction. We discuss and review the recent findings of DMD inflammation and opportunities for drug development targeting specific releasing factors from skeletal muscles. It has been speculated that nonsteroidal anti-inflammatory drugs targeting specific inflammatory factors are more effective and have less side effects for DMD compared with steroidal drugs. For example, calcium channels, reactive oxygen species, and nuclear factor-κB signaling factors are the most promising targets as master regulators of inflammatory response in DMD skeletal muscles. If they are combined with an oligonucleotide-based exon skipping therapy to restore dystrophin expression, the anti-inflammatory drug therapies may address the present therapeutic limitation of low efficiency for DMD.

    This present study was to examine the cytotoxicity and anti-inflammatory activity of gamma (γ)-irradiated genistein in murine peritoneal macrophage. Inflammation to macrophage was induced by adding the lipopolysaccharide (LPS). γ-Irradiated genistein significantly decreased the cytotoxicity to murine peritoneal macrophage in dose ranges from 5 to 10 μM than that of non-irradiated genistein. Anti-inflammatory activity within the doses less than 2 μM showed that γ-irradiated genistein treatment remarkably reduced the lipopolysaccharide-induced inflammation by decreasing the nitric oxide (NO) and cytokines (TNF-α, IL-6) production. In a structural analysis through the high pressure liquid chromatography (HPLC), γ-irradiated genistein showed a new peak production distinguished from main peak of genistein (non-irradiated). Therefore, increase of anti-inflammatory activity may closely mediate with structural changes induced by γ irradiation exposure. Based on the above result, γ-irradiation could be an effective tool for reduction of toxicity and increase of physiological activity of biomolecules.

    The present study was structured to investigate the anti-inflammatory potential of the extracts, fractions and compounds isolated from Carissa carandas (L.) roots. Bioassay guided fractionation of methanol extract based on inhibitory potential towards proinflammatory mediators (TNF-α, IL-1β and nitric oxide (NO)) led to the identification of stigmasterol (1), lupeol (2), oleanolic acid (3), carissone (4) and scopoletin (5) as potential anti-inflammatory agents. Carissone (4) (IC50 = 20.1 ± 2.69 μg/mL) and scopoletin (5) (IC50 = 24.6 ± 1.36 μg/mL) exhibited significant inhibition of NO production comparable to specific NO inhibitor (L-NAME; IC50 = 19.82 ± 1.64 μg/mL) without affecting the cell viability. Also, 4 and 5 at a concentration of 30 μM were found to inhibit 41.88-53.44% of TNF-α and IL-1β. To the best of our knowledge, this is the first report displaying the anti-inflammatory effects of C. carandas (L.) roots, partially mediated by inhibition of TNF-α, IL-1β and NO.

    New treatments are needed to improve the health of people with cystic fibrosis (CF). Reducing lung-damaging inflammation is likely to be beneficial, but specific anti-inflammatory targets have not been identified. By combining cellular immunology with a population-based genetic modifier study, we examined TLR5 as an anti-inflammatory target and modifier gene in CF. Using two pairs of human CF and control airway epithelial cells, we demonstrated that the TLR5-flagellin interaction is a major mediator of inflammation following exposure to Pseudomonas aeruginosa. To validate TLR5 as an anti-inflammatory target, we analyzed the disease modifying effects of the TLR5 c.1174C>T single nucleotide polymorphism (rs5744168) in a large cohort of CF patients (n = 2219). rs5744168 encodes a premature stop codon and the T allele is associated with a 45.5-76.3% reduction in flagellin responsiveness (p impact of TLR5 on nutritional status, this translational research provides evidence that genetic variation in TLR5 resulting in reduced flagellin responsiveness is associated with improved health indicators in adults with CF.

    Objective: To evaluate the analgesic, anti-inflammatory and anti-arthritic activity of leaves of Cassia uniflora (C. uniflora) Mill. Methods: Petroleum ether, ethyl acetate and methanolic extract of C. uniflora (100 and 200 mg/kg, body weight) was screened for analgesic (Eddy's hot plate and acetic acid induced writhing), anti-inflammatory (Carrageenan induced paw edema) and anti-arthritic (Complete Freund's Adjuvant induced arthritis). In Complete Freund's Adjuvant arthritis model degree of inflammation was evaluated by hind paw swelling, body weight, and biochemical parameters and supported by radiological analysis. Results: Treatment with extracts of C. uniflora showed significant (P<0.05) and dose dependant increase in paw licking time in Eddy's hot plate method. In writhing test, extracts were significantly reduced the number of writhes. A dose dependant and significant inhibition of edema was observed in carrageenan induced paw edema. Petroleum ether extract at a dose of 100 mg/kg body weight showed most potent and significant activity which is supported by the results of body weight, biochemical parameters and radiological analysis in complete Freund's Adjuvant arthritis model. Conclusion:The extract possesses analgesic, anti-inflammatory and anti-arthritic activity which may be mediated through the phytochemical constituents of the plant.

    Non-steroidal anti-inflammatory drugs (NSAIDS), such as ibuprofen, are widely used over-the-counter drugs to treat arthritis, but they are often associated with side effects. Herbal medicines have been used to treat various diseases such as arthritis, but the scientific profiles are not well understood. In this study, we examined, in comparison with ibuprofen, the inhibitory effects on various inflammatory markers of the most commonly used herbal medicines to treat arthritis, boswellia (Boswellia sapindales), licorice (Glycyrrhiza glabra), guggul (Commiphora wightii), and neem (Azadirachta indica). To elicit inflammatory response, we exposed mouse myoblast C2C12 cells to lipopolysaccharide (LPS). Tumor necrosis factor-alpha (TNF-α) and monocyte chemotactic protein-1 (MCP-1), which are cytokines activated during an inflammatory response, were determined. The optimal non-toxic concentration was determined by exposing different concentrations of drugs (from 0.01 to 10 mg/mL). Cell death measurement revealed that the drug concentrations lower than 0.05 mg/mL were non-toxic concentrations for each drug, and these doses were used for the main experiments. We found that neem and licorice showed robust anti-inflammatory responses compared with ibuprofen. However, boswellia and guggul did not demonstrate significant anti-inflammatory responses. We concluded that neem and licorice are more effective than ibuprofen in suppressing LPS-induced inflammation in C2C12 cells.

    Inflammation is the major causative factor of different diseases such as cardiovascular disease, diabetes, obesity, osteoporosis, rheumatoid arthritis, inflammatory bowel disease, and cancer. Anti-inflammatory drugs are often the first step of treatment in many of these diseases. The present study is aimed at evaluating the anti-inflammatory properties of isoorientin, a selective cyclooxygenase-2 (COX-2) inhibitor isolated from the tubers of Pueraria tuberosa, in vitro on mouse macrophage cell line (RAW 264.7) and in vivo on mouse paw edema and air pouch models of inflammation. Isoorientin reduced inflammation in RAW 264.7 cell line in vitro and carrageenan induced inflammatory animal model systems in vivo. Cellular infiltration into pouch tissue was reduced in isoorientin treated mice compared to carrageenan treated mice. Isoorientin treated RAW 264.7 cells and animals showed reduced expression of inflammatory proteins like COX-2, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), 5-lipoxygenase (5-LOX), and interleukin 1-β (IL-1-β) both in vitro and in vivo. The antioxidant enzyme levels of catalase and GST were markedly increased in isoorientin treated mice compared to carrageenan treated mice. These results suggest that isoorientin, a selective inhibitor of COX-2, not only exerts anti-inflammatory effects in LPS induced RAW cells and carrageenan induced inflammatory model systems but also exhibits potent antioxidant properties.

    The chemical composition of the essential oil and antioxidant and anti-inflammatory activities of the extracts from Piper miniatum were determined. GC and GC-MS analysis of the essential oil resulted in the identification of 64 components, accounting for 89.2% of the total. The major components were caryophyllene oxide (20.3%) and α-cubebene (10.4%). The antioxidant activity was evaluated by β-carotene/linoleic acid bleaching, DPPH radical scavenging and total phenolic content. In the β-carotene assay, the n-hexane extract showed the highest inhibition activity with 42.7%, while the oil gave 91.3%. The essential oil and extracts were tested for anti-inflammatory activity by using the TPA-induced mouse ear edema model and lipoxygenase assays. The essential oil exhibited significant activity in both models as an anti-inflammatory agent. The n-hexane extract showed strong activity with inhibition of 85.9% in the TPA-induced mouse ear edema model, while the chloroform extract showed the highest activity with 94.2% in the lipoxygenase assay.

    This study assessed the anti-inflammatory effects of the essential oil from Piper vicosanum leaves (OPV) and evaluated the toxicological potential of this oil through acute toxicity, genotoxicity and mutagenicity tests. The acute toxicity of OPV was evaluated following oral administration to female rats at a single dose of 2 g/kg b.w. To evaluate the genotoxic and mutagenic potential, male mice were divided into five groups: I: negative control; II: positive control; III: 500 mg/kg of OPV; IV: 1000 mg/kg of OPV; V: 2000 mg/kg of OPV. The anti-inflammatory activity of OPV was evaluated in carrageenan-induced pleurisy and paw edema models in rats. No signs of acute toxicity were observed, indicating that the LD50 of this oil is greater than 2000 mg/kg. In the comet assay, OPV did not increase the frequency or rate of DNA damage in groups treated with any of the doses assessed compared to that in the negative control group. In the micronucleus test, the animals treated did not exhibit any cytotoxic or genotoxic changes in peripheral blood erythrocytes. OPV (100 and 300 mg/kg) significantly reduced edema formation and inhibited leukocyte migration analyzed in the carrageenan-induced edema and pleurisy models. These results show that OPV has anti-inflammatory potential without causing acute toxicity or genotoxicity.

    Full Text Available “Mucositis” is the clinical term used to describe ulceration and damage of the mucous membranes of the entire gastrointestinal tract (GIT following cytotoxic cancer chemotherapy and radiation therapy common symptoms include abdominal pain, bloating, diarrhoea, vomiting, and constipation resulting in both a significant clinical and financial burden. Chemotherapeutic drugs cause upregulation of stress response genes including NFκB, that in turn upregulate the production of proinflammatory cytokines such as interleukin-1β (IL-1β, Interleukin-6 (IL-6, and tumour necrosis factor-α (TNF-α. These proinflammatory cytokines are responsible for initiating inflammation in response to tissue injury. Anti-inflammatory cytokines and specific cytokine inhibitors are also released to limit the sustained or excessive inflammatory reactions. In the past decade, intensive research has determined the role of proinflammatory cytokines in development of mucositis. However, a large gap remains in the knowledge of the role of anti-inflammatory cytokines in the setting of chemotherapy-induced mucositis. This critical paper will highlight current literature available relating to what is known regarding the development of mucositis, including the molecular mechanisms involved in inducing inflammation particularly with respect to the role of proinflammatory cytokines, as well as provide a detailed discussion of why it is essential to consider extensive research in the role of anti-inflammatory cytokines in chemotherapy-induced mucositis so that effective targeted treatment strategies can be developed.

    Lyophilized aqueous extracts obtained from Agave americana L (Agavaceae) collected in the north of Sardinia were characterized with regard to their steroidal sapogenin content. Extracts of A. americana and genins isolated from them were evaluated for anti-inflammatory properties by testing their effects on carrageenin-induced edema. The effect of orally administered genins on gastric mucous membranes was also assessed. Lyophilized extracts administered by the intraperitoneal route at doses equivalent to 200 and 300 mg/kg of fresh plant starting material, showed good anti-inflammatory activity. Doses of genins (total steroidal sapogenins, hecogenin and tigogenin) equivalent to the amount in the lyophilized extracts produced an antiedentatous effect which was much stronger and more efficacious than that obtained with an i.p. administration of 5 mg/kg of indomethacin or dexamethasone 21-phosphate at a dose equivalent to the molar content of hecogenin administered. At the doses used to evaluate the anti-inflammatory activity, the genins did not have any harmful effect on the gastric mucous membranes. Lesions occurred when significantly higher doses of hecogenin were given, but gastric damage was still less than that caused by the drugs used for comparative purposes.

    Pancreatitis-associated protein (PAP) was discovered in the pancreatic juice of rats with acute pancreatitis. PAP is a 16 kDa secretory protein structurally related to the C-type lectins although classical lectin-related function has not been reported yet. Then, it was demonstrated that PAP expression may be activated in some tissues in a constitutive or injury- and inflammation-induced manner. More recently, it has been found that PAP acts as an anti-inflammatory factor in vitro and in vivo.PAP expression can be induced by several pro- and anti-inflammatory cytokines and by itself through a JAK/STAT3-dependent pathway. PAP is able to activate the expression of the anti-inflammatory factor SOCS3 through the JAK/STAT3-dependent pathway. The JAK/STAT3/SOCS3 pathway seems to be a common point between PAP and several cytokines. Therefore,it is reasonable to propose that PAP is a new antiinflammatory cytokine.

    Yuzu (Citrus junos Tanaka) has been used as a traditional medicine in Japan. We investigated in vitro anti-inflammatory effects of limonene from yuzu peel on human eosinophilic leukemia HL-60 clone 15 cells. To examine anti-inflammatory effects of limonene on the cells, we measured the level of reactive oxygen species (ROS), monocyte chemoattractant protein-1 (MCP-1), nuclear factor (NF) kappa B, and p38 mitogen-activated protein kinase (MAPK). We found that low concentration of limonene (7.34 mmol/L) inhibited the production of ROS for eotaxin-stimulated HL-60 clone 15 cells. 14.68 mmol/L concentration of limonene diminished MCP-1 production via NF-kappa B activation comparable to the addition of the proteasomal inhibitor MG132. In addition, it inhibited cell chemotaxis in a p38 MAPK dependent manner similar to the adding of SB203580. These results suggest that limonene may have potential anti-inflammatory efficacy for the treatment of bronchial asthma by inhibiting cytokines, ROS production, and inactivating eosinophil migration.

    Antimicrobial, antifungal and anti-inflammatory effects of essential oils extracted from Chamaecyparis obtusa (EOCO) have previously been reported. In the present study, the anti-inflammatory effects of EOCO were investigated in two murine models of inflammation: Carrageenan-induced paw edema and thioglycollate-induced peritonitis, and in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophage cells. The expression levels of proinflammatory cytokines were analyzed by ELISA, the expression of nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) were determined by western blotting, and nitrite concentration was measured using Griess reagent. In mice with carrageenan-induced edema, paw thickness and the expression levels of interleukin (IL)‑1β and IL-6 in paw homogenates were significantly decreased in the EOCO (5 and 10 mg/kg) group, as compared with the control group. In mice with thioglycollate-induced peritonitis, treatment with EOCO (5 and 10 mg/kg) reduced the number of total cells and suppressed tumor necrosis factor‑α (TNF‑α), IL‑1β and IL‑6 levels in peritoneal fluid. In addition, EOCO reduced nitric oxide, TNF‑α and IL‑6 production, and suppressed iNOS and COX‑2 expression in LPS‑stimulated RAW 264.7 cells. These results suggest that EOCO may exert anti‑inflammatory effects in vivo and in vitro, and that these effects may be associated with the inhibition of inflammatory mediators. Therefore, EOCO may be considered an effective therapeutic agent for the treatment of inflammatory diseases.

    Full Text Available Summary: The present study explored the anti-inflammatory potential of aqueous root extract of Strophanthus hispidus (SPH DC (Apocynaceae in rodents, using standard laboratory models. Doses of 50, 100, 500 and 1000 mg/kg of aqueous SPH were administered orally in carrageenan-induced rat hind paw oedema, xylene-induced ear oedema in mice, and formalin-induced mice hind paw oedema (sub-acute 6 days, using indomethacin (10 mg/kg, dexamethasone 1 mg/kg and acetylsalicylic acid (Aspirin, 100 mg/kg respectively as standard drugs. The study further explored the effect of the herbal drug on some inflammatory mediators-histamine, serotonin and prostaglandin, using only the highest dose of SPH. Results obtained showed that the extract exerted a dose-dependent and significant (p<0.05 anti-inflammatory activity, which compared favourably with the positive control.  Significant inhibitions of mediators were also recorded; however, the least inhibition (42.8 % was produced in the serotonin model. Phytochemical analysis indicated the presence of flavonoids, cardiac glycosides, tannins, and anthraquinones.  It is also noteworthy that zinc, copper, manganese, lead, and chromium were the elemental constituents in the aqueous extract of SPH, some of which have been reported to possess anti-inflammatory property. While 2 g/kg of SPH administered orally did not produce any mortality, the median lethal dose by i.p route was 39.81 mg/kg, and it is thought that the lead contribute to the toxicity recorded. The pH of the herbal drug was 6.7. Our findings substantiate the local use of SPH in the treatment of acute and sub-acute inflammatory conditions, while it also suggests some possible pathways for its anti-inflammatory activity.  Lastly, since the herbal drug is liable to producing toxic effects, it must be used with caution. Industrial relevance: Herbal remedies continue to serve as an important source of conventional therapies for diverse disease conditions

    Full Text Available Scilla nervosa (Burch. Jessop (Hyacinthaceae [=Schizocarphus nervosus (Burch. Van der Merwe] is a well-known plant in traditional medicine in South Africa, used for conditions associated with pain and inflammation, such as rheumatic fever. However, the topical anti-inflammatory and antimicrobial activities of the plant have not been investigated. A bioassay-guided fractionation approach was implemented to determine the biological activities of different extracts. A crude methanol extract was prepared from the bulbs to investigate the anti-inflammatory properties in a mouse model of acute croton oil-induced auricular contact dermatitis. The non-polar and polar components present in the methanol extract were separated by extraction with dichloromethane and ethanol, respectively; and their antimicrobial activity against the invasive pathogenic microorganisms Staphylococcus aureus, Klebsiellla pneumoniae and Candida albicans was investigated using a microplate method. Oedema induced by application of croton oil was significantly reduced 3 h (~66% and 6 h (~40% after treatment with the extracts. Anti-inflammatory activity was ~1.8-fold lower at 6 h, suggesting a potent, short-acting effect. The non-polar extract exhibited greater efficacy and potency against the microorganisms than the polar extract. The non-polar extract was equipotent against S. aureus and K. pneumoniae, but twice as potent against C. albicans as against the bacteria, suggesting little discrimination between Gram-positive and Gram-negative bacteria but specificity for the fungal yeast. The polar extract was the least potent against K. pneumoniae, but 10-fold more potent against C. albicans, suggesting specificity for Gram-positive bacteria and the fungal yeast. S. nervosa contains compounds that are individually, or in combination, potent anti-inflammatory and antimicrobial agents

    This study aimed to elucidate the anti-inflammatory and related activities of mushroom Phellinus linteus. The results show that the EtOH extract of Phellinus linteus (PLE) dose-dependently inhibited the mouse ear edema induced by croton oil. Among PLE subfractions, the n-BuOH subfraction showed highest anti-inflammatory activity in croton oil-induced ear edema test. The n-BuOH subfraction also showed highest inhibitory activity on the chick embryo chorioallantoic membrane (CAM) angiogenesis in a dose-dependent manner. PLE could significantly reduce the number of writhing induced by acetic acid in mice, indicating that PLE possesses potent antinociceptive effect mediated by its anti-inflammatory activity. Mycelial extract of six different Phellinus strains were found to contain anti-angiogenic activity in the CAM assay. These results suggest that Phellinus linteus has anti-inflammatory and antinociceptive activities, in addition to its anti-angiogenic activity.

    For the past three decades, prostaglandin E2 and other arachidonic acid metabolites have been recognized as important proinflammatory mediators in bone resorption and various forms of periodontal disease. Nonsteroidal anti-inflammatory drugs are chemical compounds that selectively inhibit the synthesis of metabolites of the cyclooxygenase pathway, thereby blocking the production of prostaglandins, thromboxane, and prostacyclin. Inhibiting prostaglandin E2 synthesis with nonsteroidal anti-inflammatory drugs has been unequivocally shown in both animal and human studies to be of primary therapeutic efficacy. Recent lines of nonsteroidal anti-inflammatory drugs research have focused on the development of daily topical administration forms such as gels, toothpastes, and rinses. Furthermore, new studies have implicated prostaglandin E2 in the peri-implantitis process, opening the possibility to manage failing implants with topical nonsteroidal anti-inflammatory drug delivery systems.

    Full Text Available Objective(s:Recently anti-inflammatory effects of antidepressants have been demonstrated. Venlafaxine belongs to newer antidepressants with serotonin norepinephrine reuptake inhibition property. The pain alleviating properties of venlafaxine in different pain models such as neurogenic pain, diabetic neuropathy, and fibromyalgia have been demonstrated. Anti-inflammatory effects of venlafaxine and also its underlying mechanisms remain unclear. The present study was designed to evaluate the anti-inflammatory effects of venlafaxine and determine possible underlying mechanisms. Materials and Methods: We examined the anti-inflammatory effects of intraperitoneal (IP and intracerebroventricular (ICV administration of venlafaxine in the rat model of carrageenan-induced paw edema. Results: Our results showed that both IP (50 and 100 mg/kg and ICV (50 and 100 μg/rat injection of venlafaxine inhibited carrageenan-induced paw edema. Also IP and ICV administration of venlafaxine significantly decreased myeloperoxidase (MPO activity and interleukin (IL-1β and tumor necrosis factor (TNF-α production. Finally, we tried to reverse the anti-inflammatory effect of venlafaxine by yohimbine (5 mg/kg, IP, an alpha2-adrenergic antagonist. Our results showed that applied antagonist failed to change the anti-inflammatory effect of venlafaxine. Conclusion: These results demonstrated that venlafaxine has potent anti-inflammatory effect which is related to the peripheral and central effects of this drug. Also we have shown that anti-inflammatory effect of venlafaxine is mediated mostly through the inhibition of IL-1β and TNF-α production and decreases MPO activity in the site of inflammation.

    Full Text Available The plant Krameria pauciflora MOC et. Sessé ex DC. is used as an anti-inflammatory and antidiabetic in traditional medicine. The aim of this study was to evaluate the in vivo anti-inflammatory and antidiabetic effects of a methanol extract from the roots of K. pauciflora. Dichloromethane and ethyl acetate extracts obtained by partitioning the methanol extract were also evaluated. Complete methanol and dichloromethane extracts showed anti-inflammatory effects at 3 mg/kg. An anti-inflammatory effect similar to indomethacin (10 mg/kg was observed when the methanol and dichloromethane extracts, which contain a cycloartane-type triterpene and an sterol, were administered orally at several doses (3, 10, 30 and 100 mg/kg, whereas no anti-inflammatory effect was observed at any dose for the ethyl acetate extract, which contains catechin-type flavonoids. The antidiabetic effect of each extract was also determined. An antihyperglycaemic effect was observed in diabetic rats, but no effect in normoglycaemic animals was observed when the methanol extract was administrated at 30 mg/kg. All of the extracts exhibited radical scavenger activity. Additionally, constituents from all of the extracts were identified by NMR. This article supports the use of K. pauciflora as an anti-inflammatory because it exhibits a similar effect to indomethacin. However, its antidiabetic effect is not completely clear, although it could be useful for preventing diabetic complications.

    Rapid and efficient synthesis of a phenyl-1H-1,2,3-triazole library enabled cost-effective biological testing of a range of novel non-steroidal anti-inflammatory drugs with potential for improved drug efficacy and toxicity profiles. Anti-inflammatory activities of the phenyl-1H-1,2,3-triazole analogs synthesized in this report were assessed using the xylene-induced ear edema model in mice. At least four analogs, 2a, 2b, 2c, and 4a, showed more potent effects than the reference anti-inflammatory drug diclofenac at the same dose of 25 mg/kg. To explore relationships between the structural properties of phenyl-1H-1,2,3-triazole analogs and their anti-inflammatory activities in xylene-induced ear edema, comparative molecular field analysis was performed, and pharmacophores showing good anti-inflammatory activities were identified based on an analysis of contour maps obtained from comparative molecular field analysis. The anti-inflammatory effect on the molecular level was tested by the expression of tumor necrosis factor-alpha induced COX-2 using Western blots. Because the addition of the analog 2c caused the expression change of TNF-α induced COX-2, the molecular binding mode between 2c and COX-2 was elucidated using in silico docking.

    Neuroinflammation is a common phenomenon in the pathology of many brain diseases. In this paper we explore whether selected vitamins and fatty acids known to modulate inflammation exert an effect on microglia, the key cell type involved in neuroinflammation. Previously these nutrients have been shown to exert anti-inflammatory properties acting on specific inflammatory pathways. We hypothesized that combining nutrients acting on converging anti-inflammatory pathways may lead to enhanced anti-inflammatory properties as compared to the action of a single nutrient. In this study, we investigated the anti-inflammatory effect of combinations of nutrients based on the ability to inhibit the LPS-induced release of nitric oxide and interleukin-6 from BV-2 cells. Results show that omega-3 fatty acids, vitamins A and D can individually reduce the LPS-induced secretion of the pro-inflammatory cytokines by BV-2 cells. Moreover, we show that vitamins A, D and omega-3 fatty acids (docosahexaenoic and eicosapentaenoic) at concentrations where they individually had little effect, significantly reduced the secretion of the inflammatory mediator, nitric oxide, when they were combined. The conclusion of this study is that combining different nutrients acting on convergent anti-inflammatory pathways may result in an increased anti-inflammatory efficacy.

    Spirulina is a species of filamentous cyanobacteria that has long been used as a food supplement. In particular, Spirulina platensis and Spirulina maxima are the most important. Thanks to a high protein and vitamin content, Spirulina is used as a nutraceutical food supplement, although its other potential health benefits have attracted much attention. Oxidative stress and dysfunctional immunity cause many diseases in humans, including atherosclerosis, cardiac hypertrophy, heart failure, and hypertension. Thus, the antioxidant, immunomodulatory, and anti-inflammatory activities of these microalgae may play an important role in human health. Here, we discuss the antioxidant, immunomodulatory, and anti-inflammatory activities of Spirulina in both animals and humans, along with the underlying mechanisms. In addition, its commercial and regulatory status in different countries is discussed as well. Spirulina activates cellular antioxidant enzymes, inhibits lipid peroxidation and DNA damage, scavenges free radicals, and increases the activity of superoxide dismutase and catalase. Notably, there appears to be a threshold level above which Spirulina will taper off the antioxidant activity. Clinical trials show that Spirulina prevents skeletal muscle damage under conditions of exercise-induced oxidative stress and can stimulate the production of antibodies and up- or downregulate the expression of cytokine-encoding genes to induce immunomodulatory and anti-inflammatory responses. The molecular mechanism(s) by which Spirulina induces these activities is unclear, but phycocyanin and β-carotene are important molecules. Moreover, Spirulina effectively regulates the ERK1/2, JNK, p38, and IκB pathways. This review provides new insight into the potential therapeutic applications of Spirulina and may provide new ideas for future studies.

The inflammatory response to fiber damage is a compelling candidate mechanism for disease exacerbation. The only established pharmacological treatment for DMD is corticosteroids to suppress muscle inflammation, however this treatment is limited by its insufficient therapeutic efficacy and considerable side effects. Recent reports show the therapeutic potential of inhibiting or enhancing pro- or anti-inflammatory factors released from DMD skeletal muscles, resulting in significant recovery from muscle atrophy and dysfunction. We discuss and review the recent findings of DMD inflammation and opportunities for drug development targeting specific releasing factors from skeletal muscles. It has been speculated that nonsteroidal anti-inflammatory drugs targeting specific inflammatory factors are more effective and have less side effects for DMD compared with steroidal drugs. For example, calcium channels, reactive oxygen species, and nuclear factor-κB signaling factors are the most promising targets as master regulators of inflammatory response in DMD skeletal muscles. If they are combined with an oligonucleotide-based exon skipping therapy to restore dystrophin expression, the anti-inflammatory drug therapies may address the present therapeutic limitation of low efficiency for DMD. Keywords: calcium channels, ryanodine receptor 1, exon skipping, NF-κB, myokine, ROS

    The development of new therapeutic approaches, combining efficacy and safety against intestinal inflammation, notably inflammatory bowel disease (IBD), has emerged as an important goal due to the significant side effects and the lack of effectiveness of standard current therapies. Recently, several studies described the health-promoting effects of red wine, including anti-inflammatory properties, but the molecular mechanisms underlying its beneficial role remain largely unknown. Red wine is rich in phenolic compounds and it has been suggested that the positive effect of red wine intake might be attributed not only to the antioxidant properties of these compounds but also to the modulation of signalling cascades in connection with physiological and pathophysiological conditions such as inflammatory processes. This study assesses the potential anti-inflammatory action of a red wine extract (RWE) enriched in polyphenols in a cellular model of intestinal inflammation using cytokines-stimulated HT-29 colon epithelial cells. RWE suppressed cytokines-induced IκB degradation and interleukin-8 production in a dose-dependent manner. Coherently, key inflammatory mediators downstream NF-κB activation; notably cyclooxygenase-2 and inducible nitric oxide synthase were maintained at low levels by RWE in the presence of the cytokines. Additionally, RWE inhibited both the increase of nitric oxide derived from iNOS and of protein tyrosine nitration, a biomarker of nitrosative stress that typically requires the reaction of nitric oxide with the superoxide radical. Taken together, the anti-inflammatory action of RWE, mechanistically supported by the modulation of cascades orchestrated by NF-κB and involving nitric oxide, suggests that RWE (a readily straightforward preparation when compared with the purification of specific compounds) may represent a simple and inexpensive therapeutic strategy in the context of intestinal inflammation.

    Full Text Available Background: While curcuminoids have been reported to possess diverse biological activities, the anti-inflammatory activity of polar extracts (devoid of curcuminoids of Curcuma longa (C. longa has seldom been studied. In this study, we have investigated immune-stimulatory and anti-inflammatory activities of an aqueous based extract of C. longa (NR-INF-02 and its fractions in presence and absence of mitogens. Materials and Methods: Effects of NR-INF-02 (Turmacin TM , Natural Remedies Pvt. Ltd., Bangalore, India on proliferation, nitric oxide (NO, monocyte chemotactic protein-1 (MCP-1, interleukins (ILs and prostaglandin (PGE 2 levels of mouse splenocytes and mouse macrophage (RAW264.7 cells were determined. Results: NR-INF-02 increased splenocytes number in presence and absence of lipopolysaccharide (LPS or concanavalin A. Treatment of NR-INF-02 showed a significant increase of NO, IL-2, IL-6, IL-10, IL-12, interferon (IFN gamma, tumor necrosis factor (TNF alpha and MCP-1 production in unstimulated mouse splenocytes and mouse macrophages. Interestingly, NR-INF-02 showed potent inhibitory effect towards release of PGE 2 and IL-12 levels in LPS stimulated mouse splenocytes. Further, NR-INF-02 was fractionated into polysaccharide fraction (F1 and mother liquor (F2 to study their immune-modulatory effects. F1 was found to be more potent than F2 toward inhibiting PGE 2 and IL-12 in LPS stimulated splenocytes. Conclusion: Present findings revealed the novel anti-inflammatory property of NR-INF-02 and its polysaccharide fraction by inhibiting the secretion of IL-12 and PGE 2 in vitro.

    Chantaleela recipe is indicated for relieving fever in Thai traditional folk medicine. In the present study, Chantaleela recipe was investigated for anti-inflammatory, analgesic, antipyretic and anti-ulcerogenic activities. In preliminary investigation Chantaleela recipe was found to exert an inhibitory activity on the acute phase of inflammation as seen in ethyl phenylpropiolate-induced ear edema as well as in carrageenan-induced hind paw edema in rats. The results suggest that the anti-inflammatory activity of Chantaleela recipe may be due to an inhibition via cyclooxygenase pathway. In the analgesic test, Chantaleela recipe showed a significant analgesic activity in both the early and late phases of formalin test, but exerted the most pronounced effect in the late phase. The analgesic activity of Chantaleela recipe may act via mechanism at peripheral and partly central nervous system. In antipyretic test, Chantaleela recipe significantly decreased rectal temperature of brewer's yeast-induced hyperthermia rats, probably by inhibiting synthesis and/or release of prostaglandin E₂ in the hypothalamus. Therefore, the key mechanism of anti-inflammatory, analgesic, and antipyretic activity of the Chantaleela recipe likely involves the inhibition of the synthesis and/or release of inflammatory or pain mediators, especially prostaglandins. The oral administration of the Chantaleela recipe reduced ulcer formation in acute gastric ulcer models (EtOH/HCl-, indomethacin-, and stress-induced gastric lesions). In contrast, this recipe did not reduce the secretory rate, total acidity, and increase pH in rat stomach. These results indicated that Chantaleela seem to possess anti-ulcerogenic effect. This activity may be due to the increase of gastric mucosal resistance or potentiation of defensive factors and/or the decrease of aggressive factors but did not associate the anti-secretory activity. Moreover, the high oral doses treated did not cause acute toxicity in rats and the

    Endopleura uchi (Huber) Cuatrec. is an Amazon species traditionally used for the treatment of inflammations and female disorders. Pure bergenin was isolated from the methanolic extract of bark of E. uchi, firstly by using liquid-liquid partition chromatography followed by column chromatography over Sephadex LH-20 and then silica gel 60 flash chromatography. The structure of bergenin was identified on the basis of its NMR spectra. The in vitro anti-inflammatory activity was determined by the measurement of the inhibitory concentration (IC) of bergenin against three key enzymes: COX-1, COX-2 (cyclooxygenases) and phospholipase A2 (PLA2). These enzymes were selected because they are important targets for the discovery of new anti-inflammatory drugs associated with the biosynthesis of prostaglandins. The IC50 of bergenin for phospholipase A2 was determined as 156.6 {mu}mol L-1 and bergenin was not considered active as compared to the positive control, tioetheramide PC. Bergenin did not inhibit COX-1 as well (IC50 = 107.2 {mu}mol L-1). However, bergenin selectively inhibited COX-2 (IC50 = 1.2 {mu}mol L-1). Because of the use of E. uchi in traditional medicine, bergenin was quantified in teas prepared as prescribed in traditional medicine by RP-HPLC as being 3% in the bark of E. uchi. The inhibitory activity towards COX-2 is important, since selective inhibitors of COX-2 have been clinically validated as anti-inflammatory therapeutics due to their enhanced gastrointestinal safety.

    Full Text Available Inflammatory skin disorders, such as psoriasis and atopic dermatitis, are very common in the population; however, the treatments currently available are not well tolerated and are often ineffective. Averrhoa carambola L. (Oxalidaceae is an Asian tree that has been used in traditional folk medicine in the treatment of several skin disorders. The present study evaluates the topical anti-inflammatory effects of the crude ethanolic extract of A. carambola leaves, its hexane, ethyl acetate, and butanol fractions and two isolated flavonoids on skin inflammation. Anti-inflammatory activity was measured using a croton oil-induced ear edema model of inflammation in mice. Topically applied ethanolic extract reduced edema in a dose-dependent manner, resulting in a maximum inhibition of 73 ± 3% and an ID50 value of 0.05 (range: 0.02–0.13 mg/ear. Myeloperoxidase (MPO activity was also inhibited by the extract, resulting in a maximum inhibition of 60 ± 6% (0.6 mg/ear. All of the fractions tested caused inhibition of edema formation and of MPO activity. Treatment with the ethyl acetate fraction was the most effective, resulting in inhibition levels of 75 ± 5 and 54 ± 8% for edema formation and MPO activity, respectively. However, treatment of mice with isolated compounds [apigenin-6-C-β-l-fucopyranoside and apigenin-6-C-(2″-O-α-l-rhamnopyranosyl-β-l-fucopyranoside] did not yield successful results. Apigenin-6-C-(2″-O-α-l-rhamnopyranosyl-β-l-fucopyranoside caused only a mild reduction in edema formation (28 ± 11%. Taken together, these preliminary results support the popular use of A. carambola as an anti-inflammatory agent and open up new possibilities for its use in skin disorders.

    Deep brain stimulation (DBS) in the subgenual cingulated gyrus (SCG) is a promising new technique that may provide sustained remission in resistant major depressive disorder (MDD). Initial studies reported a significant early improvement in patients, followed by a decline within the first month of treatment, an unexpected phenomenon attributed to potential placebo effects or a physiological response to probe insertion that remains poorly understood. Here we characterized the behavioural antidepressant-like effect of DBS in the rat medial prefrontal cortex, focusing on modifications to rodent SCG correlate (prelimbic and infralimbic (IL) cortex). In addition, we evaluated the early outcome of DBS in the SCG of eight patients with resistant MDD involved in a clinical trial. We found similar antidepressant-like effects in rats implanted with electrodes, irrespective of whether they received electrical brain stimulation or not. This effect was due to regional inflammation, as it was temporally correlated with an increase of glial-fibrillary-acidic-protein immunoreactivity, and it was blocked by anti-inflammatory drugs. Indeed, inflammatory mediators and neuronal p11 expression also changed. Furthermore, a retrospective study indicated that the early response of MDD patients subjected to DBS was poorer when they received anti-inflammatory drugs. Our study demonstrates that electrode implantation up to the IL cortex is sufficient to produce an antidepressant-like effect of a similar magnitude to that observed in rats receiving brain stimulation. Moreover, both preclinical and clinical findings suggest that the use of anti-inflammatory drugs after electrode implantation may attenuate the early anti-depressive response in patients who are subjected to DBS.

    NF-κB is a crucial mediator of inflammatory and immune responses and a number of phytochemicals that can suppress this immune-regulatory transcription factor are known to have promising anti-inflammatory potential. However, we report that inducer of pro-inflammatory transcription factor NF-κB functions as an anti-inflammatory agent. Our findings reveal that a plant derived flavonoid baicalein could suppress mitogen induced T cell activation, proliferation and cytokine secretion. Treatment of CD4+ T cells with baicalein prior to transfer in to lymphopenic allogenic host significantly suppressed graft versus host disease. Interestingly, addition of baicalein to murine splenic lymphocytes induced DNA binding of NF-κB but did not suppress Concanavalin A induced NF-κB. Since baicalein did not inhibit NF-κB binding to DNA, we hypothesized that baicalein may be suppressing NF-κB trans-activation. Thioredoxin system is implicated in the regulation of NF-κB trans-activation potential and therefore inhibition of thioredoxin system may be responsible for suppression of NF-κB dependent genes. Baicalein not only inhibited TrxR activity in cell free system but also suppressed mitogen induced thioredoxin activity in the nuclear compartment of lymphocytes. Similar to baicalein, pharmacological inhibitors of thioredoxin system also could suppress mitogen induced T cell proliferation without inhibiting DNA binding of NF-κB. Further, activation of cellular thioredoxin system by the use of pharmacological activator or over-expression of thioredoxin could abrogate the anti-inflammatory action of baicalein. We propose a novel strategy using baicalein to limit NF-κB dependent inflammatory responses via inhibition of thioredoxin system.

    Full Text Available Scutellariae Radix and Liriopis Tuber have been used to treat the inflammatory diseases in traditional Korean medicine and anti-inflammatory effect of each herb has been shown partially in several articles. However, the combined extract of these medicinal herbs (SL has not been reported for its anti-inflammatory effects. In this study, we investigated the effects of SL on the creation of several proinflammatory mediators in RAW 264.7 cell mouse macrophages induced by Lipopolysaccharide (LPS. SL inhibited significantly the increase of NO, the release of intracellular calcium, the increase of interleukin-6 (IL-6, macrophage inflammatory proteins (MIP-1α, MIP-1β, and MIP-2, and granulocyte colony-stimulating factor (G-CSF in LPS-induced RAW 264.7 cell at the concentrations of 25, 50, and 100 μg/mL, and SL inhibited significantly the increase of macrophage colony-stimulating factor (M-CSF at the concentrations of 25 and 50 μg/mL, and tumor necrosis factor (TNF at the concentration of 25 μg/mL. These results implicate that SL has anti-inflammatory effects by suppressing the production of various inflammatory mediators in macrophages. But SL did not inhibit significantly the increase of granulocyte macrophage colony-stimulating factor (GM-CSF, leukemia inhibitory factor (LIF, and Regulated on Activation, Normal T cell Expressed and Secreted (RANTES; therefore, further study is demanded for the follow-up research to find out the possibility of SL as a preventive and therapeutic medicine for various inflammatory diseases.

    Full Text Available Background and objectives:Wild Sage(Salvia macrosiphon Boiss. known as “Marvak” in Persian is one of the polymorphic and abundant plants of Lamiaceae. The plants whole seeds usually soaked or boiled in hot water are widely used for inflammatory ailments in folk medicine. Documents have shown that there is scant information on the chemical constituents of this plant seeds. The current study was carried out to assess the phytochemical constituents of Salvia macrosiphon seeds as well as anti-inflammatory activities. Methods: The seed oil extracted via a Soxhlet extractor was subjected to pharmacognostic assays using High Performance Thin Layer Chromatography (HPTLC, Gas chromatography/mass spectrometry (GC/MS analysis of fatty acids and sterols as well as evaluation of the possible anti-inflammatory activities in rats. Results: Total ash, acid insoluble and water soluble ash values were determined as 51.67±7.53, 10.00±0.02 and 30.01±5.01 mg/g, respectively. HPTLC assessment revealed the presence of different steroids, triterpenes and fatty acids. Amount of sterols in oil was found 2.44, 24.92 and 4.60 mg/g for esterified β-sitosterol, free β-sitosterol and free stigmasterol, respectively. The α-linolenic acid (77.69±6.10% was the principal fatty acid. Regarding the anti-inflammatory activity, the seed oil showed low activity in the early phase of formalin test; however, could not significantly inhibit the neutrophil-induced damage by reducing MPO activity in the paws of the rat. Conclusion: The seed oil did not exhibit satisfactory effects on acute inflammation in this study but considering the rich phytosterols content, the seed and its oil can be introduced as useful dietary supplements.

    Full Text Available The acute and chronic anti-inflammatory effect of the crude extracts and fractions of Millettia aboensis leaves, a popular Nigerian traditional anti-inflammation remedy and possible mechanism of effect was investigated. Phytochemical analysis of the crude and fraction revealed the presence of anti-inflammatory phyto-compounds – terpenoids, steroids, flavonoids, tannins, saponins and glycosides. No death was recorded from acute toxicity study. The crude and methanol fraction at 300 and 200 mg/kg showed significant (p < 0.05 inhibition of egg albumin induced paw edema. Effect of the extract and fraction on topical oedema induced by xylene on mouse ear revealed that methanol fraction at 5 mg/ear had the highest activity with percentage inhibition of 61.90 % compared to the 54.76 % inhibition produced by Indomethacin. Methanol fraction at 300 mg/kg produced a significant (p < 0.05 inhibition of formaldehyde induced arthritis with percentage inhibition of 40.93 %. Result of the ulcergenic effect in rat demonstrated that both the crude and methanol fraction possess ulcergenic effect though lower than that produced by Indomethacin. Methanol fraction at 400 mg/kg also produced significant (p < 0.05 inhibition of leucocytes migration compared with the control. Both extract and methanol fraction produced stabilization effect on the heat-induced and hypotonicity induced red blood cell haemolysis. These results suggest that the ethanol leaf extract of M. aboensis possess acute and chronic anti-inflammatory activity that is most active in the methanol fraction. The activity may be as a result of combined inhibition of prostaglandin synthesis, leukocyte migration and membrane stabilization effect.

    Thymoquinone (TQ) is a bioactive component of black seed (Nigella sativa) volatile oil and has been shown to have anti-oxidative, anti-inflammatory, and anti-cancer properties. In the present study, we explored the molecular mechanisms that underlie the anti-inflammatory effect of TQ and its target proteins using lipopolysaccharide (LPS)-stimulated murine macrophage-like RAW264.7 and human monocyte-like U937 cells, together with LPS/D-galactosamine (GalN)-induced acute hepatitis and HCl/EtOH-induced gastritis mouse models. TQ strongly inhibited the production of nitric oxide (NO) and repressed NO synthase (iNOS), tumor necrosis factor (TNF)-α, cyclooxygenase (COX)−2, interleukin (IL)−6, and IL-1β expression in LPS-activated RAW264.7 cells. Treatment of LPS/D-GalN–induced hepatitis and EtOH/HCl–induced gastritis mouse models with TQ significantly ameliorated disease symptoms. Using luciferase reporter gene assays, we also showed that the nuclear levels of transcription factors and phosphorylation patterns of signaling proteins, activator protein (AP)−1, and nuclear factor (NF)-κB pathways were all affected by TQ treatment. Finally, we used additional kinase and luciferase validation assays with interleukin-1 receptor-associated kinase 1 (IRAK1) to show that IRAK1 is directly suppressed by TQ treatment. Together, these findings strongly suggest that the anti-inflammatory actions of TQ are caused by suppression of IRAK-linked AP-1/NF-κB pathways. PMID:28216638

    Full Text Available Brazilian native fruits are unmatched in their variety, but a poorly explored resource for the development of food and pharmaceutical products. The aim of this study was to evaluate the phenolic composition as well as the antioxidant and anti-inflammatory activities of the extracts of leaves, seeds, and pulp of four Brazilian native fruits (Eugenia leitonii, Eugenia involucrata, Eugenia brasiliensis, and Eugenia myrcianthes. GC-MS analyses of the ethanolic extracts showed the presence of epicatechin and gallic acid as the major compounds in these fruits. Antioxidant activity was measured using synthetic DPPH free-radical scavenging, β-carotene bleaching assay, and reactive oxygen species (ROO·, O2·-, and HOCl. The fruit extracts also exhibited antioxidant effect against biologically relevant radicals such as peroxyl, superoxide, and hypochlorous acid. In general, the pulps were the fruit fractions that exhibited the lowest antioxidant activities, whereas the leaves showed the highest ones. The anti-inflammatory activity was assessed in an in vivo model using the carrageenan-induced neutrophil migration assay, which evaluates the inflammatory response in the acute phase. The pulp, seeds, and leaves of these fruits reduced the neutrophil influx by 40% to 64%. Based on these results, we suggest that the anti-inflammatory activity of these native fruits is related to the modulation of neutrophil migration, through the inhibition of cytokines, chemokines, and adhesion molecules, as well as to the antioxidant action of their ethanolic extracts in scavenging the free-radicals released by neutrophils. Therefore, these native fruits can be useful to produce food additives and functional foods.

    Trying to surpass host defenses, fungal infections alter the immune response. Components from nonpathogenic fungi present therapeutic anti-inflammatory and immunomodulating activities. This study reveals that proteins present in a Coccidioides posadasii extract provide anti-inflammatory benefit in experimental arthritis. Zymosan was given intra-articularly to rats and mice, and groups were pretreated with C. posadasii extract either per os or intraperitoneally. Controls received the vehicle. Acute hypernociception was evaluated using articular incapacitation and von Frey methods. Cell influx and cytokine levels were assessed in joint exudates. Joint damage was evaluated by histopathology and determination of glycosaminoglycan content of the cartilage. Synovia was evaluated for cell death and inducible nitric oxide synthase (iNOS) expression using TUNEL and immunohistochemistry, respectively. Pretreatment with C. posadasii extract significantly inhibited acute and chronic cell influx, hypernociception, and provoked reduction of glycosaminoglycan loss while reducing chronic synovitis, cell death, and iNOS expression. Reduction/alkylation of C. posadasii extract abrogated these effects. C. posadasii administration did not alter TNF-α, IL-1β, IL-17, and γ-interferon levels, whereas IL-10 levels were significantly reduced. Data reveal that a C. posadasii extract reduces iNOS expression that is associated with inhibition of synovial apoptosis and decrease in IL-10 levels released into zymosan-inflamed joints. Characterization of active components excluded charged carbohydrates while pointing to a protein as responsible for these effects. In summary, systemic administration of components from a pathogenic fungus provides anti-inflammatory effects, being species-independent and orally active. Besides adding to understand host response against fungi, the results may lead to therapeutic implications.

    Full Text Available Objective: To evaluate the anti-inflammatory effect of Nardostachys jatamansi (N. jatamansi rhizome against acute, subacute and chronic models of inflammation in experimental animals. Methods: N. jatamansi rhizome extract (150 and 300 mg/kg, p.o. and the reference drugs phenylbutazone (100 mg/kg, p.o. and acetylsalicylic acid (300 mg/kg, p.o. were evaluated using models for inflammation (autacoids induced hind paw oedema, formaldehyde induced hind paw oedema, carrageenin-induced paw oedema, cotton pellet granuloma and subcutaneous air pouch model. Results: In acute inflammation as produced by carrageenin 29.06% and 55.81%, by histamine 25.0% and 39.28%, by 5-hydroxytryptamine 21.37% and 36.95% and by prostaglandin E2- induced hind paw oedema 31.03% and 44.82% protection was observed. While in subacute antiinflammatory models using formaldehyde-induced hind paw oedema (after 1.5 h 13.88% and 33.33% and in chronic anti-inflammatory model using cotton pellet granuloma 7.4% and 17.58% protection from inflammation was observed. N. jatamansi rhizome extract also inhibited the inflammatory mediators (nitric oxide by 12.81% and 38.41%, by prostaglandin E2 12.58% and 47.82% while by TNF-α 13.51% and 41.89% produced in the pouch. Conclusions: The results of this study strongly indicate the protective effect of N. jatamansi rhizome extract against acute, subacute and chronic models of inflammation, which may be attributed to its anti-inflammatory potential.

    We describe the preparation, physico-chemical characterization and anti-inflammatory properties of liposomes containing the superparamagnetic nanoparticle Nanotex, the fluorescent dye Rhodamine-100 and omega-3 polyunsaturated fatty acid ethyl ester (ω-3 PUFA-EE), as theranostic anti-inflammatory agents. Liposomes were prepared after drying chloroform suspensions of egg phosphatidylcholine, hydration of the lipid film with aqueous phases containing or not Nanotex, Rhodamine-100 dye or ω-3 PUFA-EE, and eleven extrusion steps through nanometric membrane filters. This resulted in uniform preparations of liposomes of approximately 200 nm diameter. Extraliposomal contents were removed from the preparation by gel filtration chromatography. High Resolution Magic Angle Spinning 1H NMR Spectroscopy of the liposomal preparations containing ω-3 PUFA-EE revealed well resolved 1H resonances from highly mobile ω-3 PUFA-EE, suggesting the formation of very small (ca. 10 nm) ω-3 PUFA-EE nanogoticules, tumbling fast in the NMR timescale. Chloroform extraction of the liposomal preparations revealed additionally the incorporation of ω-3 PUFA-EE within the membrane domain. Water diffusion weighted spectra, indicated that the goticules of ω-3 PUFA-EE or its insertion in the membrane did not affect the average translational diffusion coefficient of water, suggesting an intraliposomal localization, that was confirmed by ultrafiltration. The therapeutic efficacy of these preparations was tested in two different models of inflammatory disease as inflammatory colitis or the inflammatory component associated to glioma development. Results indicate that the magnetoliposomes loaded with ω-3 PUFA-EE allowed MRI visualization in vivo and improved the outcome of inflammatory disease in both animal models, decreasing significantly colonic inflammation and delaying, or even reversing, glioma development. Together, our results indicate that magnetoliposomes loaded with ω-3 PUFA-EE may become

    Essential oil extracted from Chamaecyparis obtusa (EOCO) consists of several monoterpenes with anti-inflammatory effects. Monoterpenes are expected to have an analgesic effect through inhibition of pro-inflammatory mediators. The present study investigated the anti-nociceptive and anti-inflammatory effects of EOCO in animal models of pain. Intraperitoneal injection with EOCO (5 or 10mg/kg), aspirin (positive control, 300mg/kg), or DMSO (negative control) was performed 1h before the nociception tests: acetic acid-induced writhing response, formalin test, and hot plate test in mice, and acidic saline-induced allodynia in rats. The expression of pro-inflammatory cytokines and pro-inflammatory enzymes in formalin-injected paws was determined by ELISA and western blotting, respectively. Treatment with EOCO significantly reduced acetic acid-induced writhing and paw-licking time in late response of the formalin tests. The anti-nociceptive effect was comparable with aspirin. However, EOCO did not affect the reaction time of licking of the hind paws or jumping in hot plate test and the mechanical withdrawal thresholds in acidic saline-induced allodynia model. Formalin-injected paws of mice treated with EOCO revealed the down-regulated expression of tumor necrosis factor-α, interleukin-1β, inducible nitric oxide synthase, and cyclooxygenase-2, as compared with those of control mice. These data showed the anti-nociceptive and anti-inflammatory effects of EOCO. The pain-relieving effect might be attributed to inhibition of peripheral pain in association with inflammatory response. EOCO could be a useful therapeutic strategy to manage pain and inflammatory diseases.

    Objective:To investigate antioxidant and anti-inflammatory effects of Tagetes minuta (T. minuta) essential oil. Methods:In the present study T. minuta essential oil was obtained from leaves of T. minuta via hydro-distillation and then was analyzed by gas chromatography-mass spectrometry. The anti-oxidant capacity of T. minuta essential oil was examined by measuring reactive oxygen, reactive nitrogen species and hydrogen peroxide scavenging. The anti-inflammatory activity of T. minuta essential oil was determined through measuring NADH oxidase, inducible nitric oxide synthase and TNF-αmRNA expression in lipopolysacharide-stimulated murine macrophages using real-time PCR. Results:Gas chromatography-mass spectrometry analysis indicated that the main components in the T. minuta essential oil were dihydrotagetone (33.86%), E-ocimene (19.92%), tagetone (16.15%), cis-β-ocimene (7.94%), Z-ocimene (5.27%), limonene (3.1%) and epoxyocimene (2.03%). The T. minuta essential oil had the ability to scavenge all reactive oxygen/reactive nitrogen species radicals with IC50 12-15 μg/mL, which indicated a potent radical scavenging activity. In addition, T. minuta essential oil significantly reduced NADH oxidase, inducible nitric oxide synthaseand TNF-αmRNA expression in the cells at concentrations of 50 μg/mL, indicating a capacity of this product to potentially modulate/diminish immune responses. Conclusions:T. minuta essential oil has radical scavenging and anti-inflammatory activities and could potentially be used as a safe effective source of natural anti-oxidants in therapy against oxidative damage and stress associated with some inflammatory conditions.

    Asparagus racemosus root extracts (AR) have been reported to possess a variety of pharmacological properties. The aim of the present study was to develop liposomes of AR and to assess their physicochemical characteristics and anti-inflammatory activity in the monocytic leukemia cell line THP-1. Liposomes containing various ratios of AR to lipid and a phosphatidylcholine to cholesterol molar ratio of 7:3 were prepared by thin-film hydration (TF), reverse-phase evaporation (REV) and polyol dilution (PD). The results showed that AR liposomes prepared by TF had a multilamellar structure and a large size, whereas those prepared by REV and PD were oligolamellar in structure, and of a smaller size. The particle sizes and zeta potentials of the liposomes ranged from 196.5 to 456.6 nm and from −4.34 to −18.94 mV, respectively. The AR to lipid ratio was shown to have no significant influence on particle size, while the zeta potential generally increased with increasing AR to lipid ratio. The highest entrapment efficiency values were detected in liposomes with an AR to lipid ratio of 1:5, and for liposomes prepared by TF, REV and PD methods, the entrapment efficiencies were 55.71±2.04, 56.21±3.59 and 67.68±1.37%, respectively. AR was found to exert no toxicity on THP-1 cells. The maximum anti-inflammatory activities of AR and AR liposomes, evaluated in terms of the percentage inhibition of tumor necrosis factor-α in THP-1 cells, were ~52% at a concentration of 1 µg/ml. It can be concluded from the present study that AR liposomes have the potential to be used a formulation for topical and/or transdermal drug delivery to provide anti-inflammatory activity.

    In addition to transiently inhibiting cell cycle progression and sterilizing those cells capable of proliferation, irradiation disturbs the homeostasis effected by endogenous mediators of intercellular communication (humoral component of tissue response to radiation). Changes in the mediator levels may modulate radiation effects either by a assisting a return to normality (e.g., through a rise in H-type cell lineage-specific growth factors) or by aggravating the damage. The latter mode is illustrated with reports on changes in eicosanoid levels after irradiation and on results of empirical treatment of radiation injuries with anti-inflammatory drugs. Prodromal, acute and chronic effects of radiation are accompanied by excessive production of eicosanoids (prostaglandins, prostacyclin, thromboxanes and leukotrienes). These endogenous mediators of inflammatory reactions may be responsible for the vasodilatation, vasoconstriction, increased microvascular permeability, thrombosis and chemotaxis observed after radiation exposure. Glucocorticoids inhibit eicosanoid synthesis primarily by interfering with phospholipase A[sub 2] whilst non-steroidal anti-inflammatory drugs prevent prostaglandin/thromboxane synthesis by inhibiting cycloxygenase. When administered after irradiation on empirical grounds, drugs belonging to both groups tend to attenuate a range of prodomal, acute and chronic effects of radiation in man and animals. Taken together, these two sets of observations are highly suggestive of a contribution of humoral factors to the adverse responses of normal tissues and organs to radiation. A full account of radiation damage should therefore consist of complementary descriptions of cellular and humoral events. Further studies on anti-inflammatory drug treatment of radiation damage to normal organs are justified and desirable. (orig.).

    Full Text Available We previously demonstrated that the organic extract of Spirulina platensis (SPE, an edible blue-green alga, possesses potent anti-inflammatory effects. In this study, we investigated if the regulation of histone deacetylases (HDACs play a role in the anti-inflammatory effect of SPE in macrophages. Treatment of macrophages with SPE rapidly and dose-dependently reduced HDAC2, 3, and 4 proteins which preceded decreases in their mRNA levels. Degradation of HDAC4 protein was attenuated in the presence of inhibitors of calpain proteases, lysosomal acidification, and Ca2+/calmodulin-dependent protein kinase II, respectively, but not a proteasome inhibitor. Acetylated histone H3 was increased in SPE-treated macrophages to a similar level as macrophages treated with a pan-HDAC inhibitor, with concomitant inhibition of inflammatory gene expression upon LPS stimulation. Knockdown of HDAC3 increased basal and LPS-induced pro-inflammatory gene expression, while HDAC4 knockdown increased basal expression of interleukin-1β (IL-1β, but attenuated LPS-induced inflammatory gene expression. Chromatin immunoprecipitation showed that SPE decreased p65 binding and H3K9/K14 acetylation at the Il-1β and tumor necrosis factor α (Tnfα promoters. Our results suggest that SPE increased global histone H3 acetylation by facilitating HDAC protein degradation, but decreases histone H3K9/K14 acetylation and p65 binding at the promoters of Il-1β and Tnfα to exert its anti-inflammatory effect.

    Moringa oleifera is a bush of African savannah, used in folk Medicine for the treatment of rheumatic and articulary pain. We have tested the anti-inflammatory action of an aqueous extract of root in rats with weight between 120 and 160 g. We administered per os either distilled water (control group), the aqueous root extract (750 mg/kg or 1000 mg/kg) or indomethacin (10 mg/kg) 30 min before an oedema was induced in the rat-paw by subcutaneous injection of carrageenin. The rat-paw volume was measured 1, 3 and 5 hours after injection of carrageenin. At a dose of 750 mg/kg the Moringa oleifera treatment significantly inhibited the development of oedema at 1, 3 and 5 hours (reduction by 53.5, 44.6 and 51.1% respectively). Increasing the dose of Moringa oleifera to 1000 mg/kg did not increase the inhibitory effect on oedema development at 1 and 3 hours, whereas this dose potentiated the oedema at 5 hours. Treatment with indomethacin significantly inhibited the development of oedema 1, 3 and 5 hours (49.1, 82.1 and 46.9% respectively). These findings indicate that an aqueous root extract of Moringa oleifera at 750 mg/kg reduces the carrageenin induced oedema to similar extent as the potent anti-inflammatory drug indomethacin. Moreover, these results provide further evidence that the roots of Moringa oleifera contain anti-inflammatory principle that may be useful in the treatment of the acute inflammatory conditions.

    Produced worldwide at 1.2m tons per year, fibrous clays are used in the production of pet litter, animal feed stuff to roof parcels, construction and rheological additives, and other applications needing to replace long-fiber length asbestos. To the authors' knowledge, however, information on the beneficial effects of fibrous clays on health remains scarce. This paper reports on the anti-inflammatory, anti-bacterial, and cytotoxic activity by sepiolite (Vallecas, Spain) and palygorskite (Torrejon El Rubio, Spain). The anti-inflammatory activity was determined using the 12-O-tetradecanoylphorbol-13-acetate (TPA) and myeloperoxidase (MPO) methods. Histological cuts were obtained for quantifying leukocytes found in the epidermis. Palygorkite and sepiolite caused edema inhibition and migration of neutrophils ca. 68.64 and 45.54%, and 80 and 65%, respectively. Fibrous clays yielded high rates of infiltration, explained by cleavage of polysomes and exposure of silanol groups. Also, fibrous clays showed high inhibition of myeloperoxidase contents shortly after exposure, but decreased sharply afterwards. In contrast, tubular clays caused an increasing inhibition of myeloperoxidase with time. Thus, clay structure restricted the kinetics and mechanism of myeloperoxidase inhibition. Fibrous clays were screened in vitro against human cancer cell lines. Cytotoxicity was determined using the protein-binding dye sulforhodamine B (SRB). Exposing cancer human cells to sepiolite or palygorskite showed growth inhibition varying with cell line. This study shows that fibrous clays served as an effective anti-inflammatory, limited by chemical transfer and cellular-level signals responding exclusively to an early exposure to clay, and cell viability decreasing significantly only after exposure to high concentrations of sepiolite.

    Aim: Chenopodium opulifolium is a specie of the Chenopodiaceae commonly used as vegetables in local diet and for treating different ailment in Uganda. This study was conducted to evaluate the antioxidant, antinociceptive and anti-inflammatory effects of the aqueous extract of C. opulifolium leaves (AECO). Materials and Methods: The dried leaf of the plant was extracted by maceration in water. Qualitative and quantitative phytochemical analysis, antioxidants, and membrane stabilizing effects were determined in the extract. The extract was then investigated for acute toxicity, antinociceptive (writhing, hot plate and open field test), and anti-inflammatory (egg albumin-induced paw edema) effects in rodents. Results: Phytochemical analysis revealed the presence of alkaloids, tannins, phlobatannins, flavonoids, and saponins in AECO. Total caffeic acid derivatives and total flavonoids content were 91.7 mgCAE/g sample and 94.7 mgRE/g sample, respectively. AECO demonstrated antioxidant effects in both 1,1-diphenyl-2-picryl-hydrazyl and NO assays. Significant membrane stabilizing activity was observed in both the heat and hypotonic solution-induced lysis of erythrocytes. The acute toxicity test showed that AECO (5000 mg/kg) did not cause any significant change in behavior or death in rats. AECO (100-400 mg/kg) produced a significant antinociceptive effect in both the writhing and hot plate tests, but no significant reduction in the locomotory activity in mice. Furthermore, the extract significantly (P < 0.05) reduced egg albumin-induced rat paw edema by 44.2%, 44.5%, and 51.2%, respectively, after 120 min. Conclusion: The results showed that C. opulifolium extract possesses significant antioxidant, antinociceptive and anti-inflammatory effects, and these affirm the reasons for its folkloric use.

    Erythropoietin is a potent stimulator of erythroid progenitor cells, which is able to inhibit NF-kB activation, due to its pleiotropic properties, thus promoting an anti-inflammatory effect. As inflammatory bowel disease is a chronic disease with reduced quality of life, and the current pharmacotherapy only induces or maintains the patient in remission, there is a crucial need of new pharmacological approaches. The main objective of this study was to evaluate the effect of erythropoietin in the TNBS-induced colitis model in mice with a normal intestinal flora. Mice with TNBS-induced colitis were treated with a daily dose of erythropoietin at 500 IU/kg bw/day and 1000 IU/Kg bw/day IP during 4 days. As to clinical symptoms/signs, erythropoietin attenuated the decreased body-weight and reduced diarrhoea and oedema of the anus registered in the non-treated mice group in a dose-dependent manner. The anti-inflammatory properties of erythropoietin in the TNBS-induced colitis were confirmed by suppression of pro-inflammatory mediators, such as TNF-α, IL-1β and MPO, as well as a significant increase in the anti-inflammatory cytokine, IL-10, was promoted. These treated mice also presented a reduction in haemoglobin faecal and ALP, suggesting a beneficial effect of erythropoietin in the haemorrhagic focus and destruction of the enterocyte associated with the colon injury induced by TNBS, respectively. The histopathological score was reduced after treatment with erythropoietin, decreasing the severity and extension of the colitis. Furthermore, renal and hepatic biomarkers, as well as haematocrit concentration, remained stabilized after treatment. In conclusion, erythropoietin reduces the inflammatory response associated with TNBS-induced colitis in mice.

    Full Text Available Abstract Background Chitosan, a polymer derived from chitin, has been used for nasal drug delivery because of its biocompatibility, biodegradability and bioadhesiveness. Theophylline is a drug that reduces the inflammatory effects of allergic asthma but is difficult to administer at an appropriate dosage without causing adverse side effects. It was hypothesized that adsorption of theophylline to chitosan nanoparticles modified by the addition of thiol groups would improve theophylline absorption by the bronchial epithelium and enhance its anti-inflammatory effects. Objectives We sought to develop an improved drug-delivery matrix for theophylline based on thiolated chitosan, and to investigate whether thiolated chitosan nanoparticles (TCNs can enhance theophylline's capacity to alleviate allergic asthma. Methods A mouse model of allergic asthma was used to test the effects of theophylline in vivo. BALB/c mice were sensitized to ovalbumin (OVA and OVA-challenged to produce an inflammatory allergic condition. They were then treated intranasally with theophylline alone, chitosan nanoparticles alone or theophylline adsorbed to TCNs. The effects of theophylline on cellular infiltration in bronchoalveolar lavage (BAL fluid, histopathology of lung sections, and apoptosis of lung cells were investigated to determine the effectiveness of TCNs as a drug-delivery vehicle for theophylline. Results Theophylline alone exerts a moderate anti-inflammatory effect, as evidenced by the decrease in eosinophils in BAL fluid, the reduction of bronchial damage, inhibition of mucus hypersecretion and increased apoptosis of lung cells. The effects of theophylline were significantly enhanced when the drug was delivered by TCNs. Conclusion Intranasal delivery of theophylline complexed with TCNs augmented the anti-inflammatory effects of the drug compared to theophylline administered alone in a mouse model of allergic asthma. The beneficial effects of theophylline in

    Full Text Available We investigated the anti-inflammatory, antinociceptive and ulcerogenic activity of a zinc-diclofenac complex (5.5 or 11 mg/kg in male Wistar rats (180-300 g, N = 6 and compared it to free diclofenac (5 or 10 mg/kg and to the combination of diclofenac (5 or 10 mg/kg and zinc acetate (1.68 or 3.5 mg/kg. The carrageenin-induced paw edema and the cotton pellet-induced granulomatous tissue formation models were used to assess the anti-inflammatory activity, and the Hargreaves model of thermal hyperalgesia was used to assess the antinociceptive activity. To investigate the effect of orally or intraperitoneally (ip administered drugs on cold-induced gastric lesions, single doses were administered before exposing the animals to a freezer (-18ºC for 45 min in individual cages. We also evaluated the gastric lesions induced by multiple doses of the drugs. Diclofenac plus zinc complex had the same anti-inflammatory and antinociceptive effects as diclofenac alone. Gastric lesions induced by a single dose administered per os and ip were reduced in the group treated with zinc-diclofenac when compared to the groups treated with free diclofenac or diclofenac plus zinc acetate. In the multiple dose treatment, the complex induced a lower number of the most severe lesions when compared to free diclofenac and diclofenac plus zinc acetate. In conclusion, the present study demonstrates that the zinc-diclofenac complex may represent an important therapeutic alternative for the treatment of rheumatic and inflammatory conditions, as its use may be associated with a reduced incidence of gastric lesions.

    Full Text Available The aim of this research was to investigate the anti-apoptotic, antioxidant and anti-inflammatory properties of menthol against ethanol-induced gastric ulcers in rats. Wistar rats were orally treated with vehicle, carbenoxolone (100 mg/kg or menthol (50 mg/kg and then treated with ethanol to induce gastric ulcers. After euthanasia, stomach samples were prepared for histological slides and biochemical analyses. Immunohistochemical analyses of the cytoprotective and anti-apoptotic heat-shock protein-70 (HSP-70 and the apoptotic Bax protein were performed. The neutrophils were manually counted. The activity of the myeloperoxidase (MPO was measured. To determine the level of antioxidant functions, the levels of glutathione (GSH, glutathione peroxidase (GSH-Px, glutathione reductase (GR and superoxide dismutase (SOD were measured using ELISA. The levels of the pro-inflammatory cytokines tumor necrosis factor-α (TNF-α and interleukin-6 (IL-6 and the anti-inflammatory cytokine interleukin-10 (IL-10 were assessed using ELISA kits. The menthol treated group presented 92% gastroprotection compared to the vehicle-treated group. An increased immunolabeled area was observed for HSP-70, and a decreased immunolabeled area was observed for the Bax protein in the menthol treated group. Menthol treatment induced a decrease in the activity of MPO and SOD, and the protein levels of GSH, GSH-Px and GR were increased. There was also a decrease in the levels of TNF-α and IL-6 and an increase in the level of IL-10. In conclusion, oral treatment with menthol displayed a gastroprotective activity through anti-apoptotic, antixidant and anti-inflammatory mechanisms.

Materials and MethodsFor evaluating of analgesic and anti-inflammatory activity, we used the carrageenan- and dextran-induced paw oedema, acetic acid-induced writhing, tail flick and formalin pain tests.ResultsThe extract of T. chamaedrys (50–200 mg/kg and acetylsalicylic acid (100 mg/kg produced a significant (P< 0.01 inhibition of the second phase response in the formalin pain model, while only the high dose (200 mg/kg of the extract showed an analgesic effect in the first phase. The extract also inhibited acetic acid-induced abdominal writhes in a dose-dependent manner. The tail flick latency was dose dependently enhanced by the extract but this was significantly (P< 0.05 lower than that produced by morphine (10 mg/kg. The extract (25–250 mg/kg administered 1 hr before carrageenan-induced paw swelling produced a dose dependent inhibition of the oedema. No effect was observed with the dextran-induced oedema model. Results of the phytochemical screening show the presence of alkaloids, flavonoids and triterpenoids in the extract.ConclusionThe data obtained also suggest that the anti-inflammatory and analgesic effects of the extract may be mediated via both peripheral and central mechanisms. The role of alkaloids, flavonoids and triterpenoids will evaluate in future studies.

    Full Text Available Background & objectives: Antidepressants are being used as analgesics for various pain related disorders like neuropathic and non neuropathic pain. Although their analgesic activity is well recognized but anti-inflammatory potential of antidepressants is still inconclusive. Since the antidepressants are used for longer duration, it becomes important to elucidate effect of anti-depressants on blood pressure and gastric mucosa. This study was undertaken to evaluate the anti-inflammatory potential of various antidepressant drugs as well as their effect on blood pressure and gastric tolerability on chronic administration in rats. Methods: Rat paw oedema model was used for studying anti-inflammatory activity, single dose of test drug (venlafaxine 20 and 40 mg/kg, amitryptline 25 mg/kg, fluoxetine 20 mg/kg was administered intraperitoneally 45 min prior to administration of 0.1 ml of 1 per cent carrageenan in sub-planter region. Oedema induced in test group was compared with normal saline treated control group. For studying effect on blood pressure and gastric tolerability, test drugs were administered for 14 days. Blood pressure was recorded on days 0, 7 and 14 using tail cuff method. On day 14, 4 h after drug administration, rats were sacrificed and stomach mucosa was examined for ulcerations. Results: Pretreatment of rats with venlafaxine (40 mg/kg resulted in a significant decrease in paw oedema as compared to control (2.4 ± 0.15 to 1.1 ± 0.16 ml, P<0.01. Similarly, in the group pretreated with fluoxetine, significant decrease in paw oedema was observed in comparison to control (P<0.05. Significant change in mean blood pressure was seen in rats pretreated with venlafaxine 40 mg/kg (126.7 ± 4.2 to 155.2 ± 9.7, P<0.05 and fluoxetine (143.5 ± 2.6 to 158.3 ± 1.2, P<0.05 on day 7. No significant difference with regard to gastric tolerability was observed among groups. Interpretation & conclusions: Our findings showed significant anti-inflammatory

    1995-01-01

    Full Text Available The increasing scientific information clearly demonstrates the important role of inflammation in asthma. This evidence has led physicians to focus their treatment on the elimination of inflammation instead of working solely against bronchoconstriction. Steroids and nonsteroidal agents are currently used to prevent this inflammatory component. This paper focuses only on nonstcroidal anti-inflammatory agents such as sodium cromoglycate, nedocromil sodium and ketotifen and their use in pediatric asthma. The discussion on each medication addresses its mechanism of action, the evidence concerning its efficacy in pediatrics (ie, clinical pharmacology, acute bronchial challenge, late asthmatic response, bronchial hyperrcactivity, clinical efficacy and the pediatric dose.

    The flavonoid pattern of an acetonic extract of Grindelia robusta Nutt. was investigated in detail. The flavonoids were enriched by CC. In addition to twelve known methylated exudate flavonols four compounds were identified for the first time in G. robusta. Several substances of the flavonoid complex, among them the main compounds quercetin-3-methylether and 6-OH-kaempferol-3,6-dimethylether, were tested for their activity to inhibit neutrophil elastase. Quercetin-3-methylether was shown to be most active with an IC(50) of 19 microM, thus obviously contributing to the anti-inflammatory activity of the drug.

    Full Text Available Increasing evidence suggests that prostatic inflammation plays a key role in the development of prostate cancer. It remains controversial whether non-steroidal anti-inflammatory drugs (NSAIDs reduce the risk of prostate cancer. Here, we investigate how a previously reported inverse association between NSAID use and the risk of aggressive prostate cancer is modulated by variants in several inflammatory genes. We found that NSAIDs may have differential effects on prostate cancer development, depending on one’s genetic makeup. Further study of these inflammatory pathways may clarify the mechanisms through which NSAIDs impact prostate cancer risk.

    of proteins with anti-inflammatory properties and in this review we gather together some recent significant advances regarding the isolation and proteomic identification of these minor constituents of both human and bovine milk. We introduce the process of inflammation, with a focus on the immature gut...... factors, lactoperoxidase, superoxide dismutase, platelet-activating factor acetylhydrolase, alkaline phosphatase, and growth factors (TGF-β, IGF-I and IGF-II, EGF, HB-EGF). The effects of milk fat globule proteins, such as TLR-2, TLR-4, sCD14 and MFG-E8/lactadherin, are also discussed. Finally, we...

    Bauhinia variegata Linn. (Leguminosae) is commonly known as 'Kachnar' in Hindi. It is distributed almost throught India. Its powdered bark is traditionally used for tonic, astrain, ulcers. It is also useful in skin diseases. The roots are used as antidote to snake poison. The present article deals with the isolation and structural elucidation of a novel flavonol glycoside 5,7,3',4'-tetrahydroxy-3-methoxy-7-O-alpha-L-rhamnopyranosyl(1-->3)-O-beta-galactopyranoside (1) from the roots of Bauhinia Variegata and its structure was identified by spectral analysis and chemical degradations. The novel compound (1) showed anti-inflammatory activity.

    Full Text Available Summary: Since in our previous study, Duhuo Jisheng Wan (DJW, which means pill of pubescent angelica root and mulberry mistletoe combination, demonstrates clinically comparable efficacy to diclofenac in the symptomatic treatment of osteoarthritis (OA of the knee after 4 weeks of treatment.  Therefore, in order to verify its mechanisms of action, this study was performed to investigate the antinociceptive and anti-inflammatory activities of DJW in various animal models.  The antinociceptive activity of DJW was investigated by using the formalin test in mice model.  The acute inflammatory model using the carrageenin-induced hind paw edema in rats and the chronic inflammatory model using the cotton pellet-induced granuloma formation in rats were utilized.  Results showed that DJW possessed a marked antinociceptive activity in both phases of the formalin test in mice.  However, in the carrageenin-induced hind paw edema model, which is known to be sensitive to cyclooxygenase (COX inhibitors, DJW showed an insignificant anti-inflammatory effect, and in the cotton pellet-induced granuloma model, it had no antigranuloma formation and showed no effect on the transudate weight.  In addition, DJW showed no suppressive effects on weight gain and the thymus weight of the rats.  In conclusion, the overall results demonstrate that DJW possess both central and peripheral antinociceptive activities.  However, its anti-inflammatory activity, if any, could not be demonstrated in these two inflammatory models in the present study and remains to be elucidate.   Industrial relevance: Since drug therapy in OA patients, such as paracetamol, non-steroidal anti-inflammatory drugs (NSAIDs, and topical analgesics may prove ineffective in some patients, and long-term therapy with NSAIDs often have been associated with serious adverse effects.  Such patients are turning increasingly to herbal medicines and DJW may be an alternative since it demonstrates clinically
