    macrophage activation syndrome, sepsis, and liver disease. Moreover, sCD163 is a general risk marker of comorbidity and mortality in several chronic inflammatory disease states. Recently, sCD163 has been shown to be strongly associated with later development of type 2 diabetes in both lean and obese subjects......, likely due to macrophage infiltration of adipose tissue and the liver. This review summarizes the current knowledge on the regulation of sCD163 in normal and pathological states and also deals with analytical aspects of sCD163 measurements in biological samples....

    Sickle cell disease (SCD) is characterized by vasculopathy, which has been causally linked to intravascular haemolysis and high levels of free plasma haemoglobin. Soluble CD163 (sCD163) is implicated in the clearance of free plasma haemoglobin and high plasma concentrations have been linked to...... arterial disease. We therefore investigated the value of sCD163 as a biomarker in children with SCD, and also measured haptoglobin levels in this population. We measured sCD163 in 25 control children with no haemoglobinopathy, 41 with sickle cell anaemia (HbSS) in the steady state, 27 with HbSS taking...

    Visceral fat differs from subcutaneous fat by higher local inflammation and increased release of IL-6 and free fatty acids (FFA) which contribute to hepatic steatosis. IL-6 has been shown to upregulate the monocyte/macrophage specific receptor CD163 whose soluble form, sCD163, is increased in inflammatory diseases. Here, it was analyzed whether CD163 and sCD163 are differentially expressed in the human fat depots and fatty liver. CD163 mRNA and protein were similarly expressed in paired samples of human visceral and subcutaneous fat, and comparable levels in portal venous and systemic venous blood of liver-healthy controls indicate that release of sCD163 from visceral adipose tissue was not increased. CD163 was also similarly expressed in steatotic liver when compared to non-steatotic tissues and sCD163 was almost equal in the respective sera. Concentrations of sCD163 were not affected when passing the liver excluding substantial hepatic removal/release of this protein. A high concentration of IL-6 upregulated CD163 protein while physiological doses had no effect. However, sCD163 was not increased by any of the IL-6 doses tested. FFA even modestly decreased CD163 and sCD163. The anti-inflammatory mediators fenofibrate, pioglitazone, and eicosapentaenoic acid (EPA) did not influence sCD163 levels while CD163 was reduced by EPA. These data suggest that in humans neither visceral fat nor fatty liver are major sources of sCD163. PMID:21839737

    Full Text Available OBJECTIVE: We investigated serum soluble CD163 (sCD163 levels for use in the diagnosis, severity assessment, and prognosis of sepsis in the critical ill patients and compared sCD163 with other infection-related variables. METHODS: During july 2010 and April 2011, serum was obtained from 102 sepsis patients (days 1, 3, 5, 7, and 10 after admission to an ICU and 30 systemic inflammatory response syndrome (SIRS patients with no sepsis diagnosed. Serum levels of sCD163, procalcitonon (PCT, and C reactive protein (CRP were determined respectively. Sequential organ failure assessment (SOFA scores for sepsis patients were also recorded. Then evaluated their roles in sepsis. RESULTS: The sCD163 levels were 0.88(0.78-1.00 ug/mL for SIRS patients, 1.50(0.92-2.00 ug/mL for moderate sepsis patients, and 2.95(2.18-5.57 ug/mL for severe sepsis patients on day 1. The areas under the ROC curves for sCD163, CRP, and PCT for the diagnosis of sepsis were, respectively, 0.856(95%CI: 0.791-0.921, 0.696(95%CI: 0.595-0.797, and 0.629(95%CI: 0.495-0.763, At the recommended cut-off 1.49 ug/mL for sCD163, the sensitivity is 74.0% with 93.3% specificity. Based on 28-day survivals, sCD163 levels in the surviving group stay constant, while they tended to gradually increase in the non-surviving group.The area under the ROC curve for sCD163 for sepsis prognosis was 0.706(95%CI 0.558-0.804. Levels of sCD163 with cut-off point >2.84 ug/mL have sensitivity of 55.8.0%, specificity 80.4%. Common risk factors for death and sCD163 were included in multivariate logistic regression analysis; the odds ratios (OR for sCD163 and SOFA scores for sepsis prognosis were 1.173 and 1.396, respectively (P<0.05. Spearman rank correlation analysis showed that sCD163 was weakly, but positively correlated with CRP, PCT, and SOFA scores (0.2< r <0.4, P<0.0001, but not with leukocyte counts (r <0.2, P = 0.450. CONCLUSION: Serum sCD163 is superior to PCT and CRP for the diagnosis of sepsis and

    Macrophages are crucially involved in the pathophysiology of acute pancreatitis. Soluble CD163 (sCD163) is specifically released from macrophages and systemic levels are increased in inflammatory diseases. Here, sCD163 was measured in serum of 50 patients with acute pancreatitis to find out possible associations with disease activity. Admission levels of systemic sCD163 were nearly three-fold higher in patients with acute pancreatitis compared to controls. In patients sCD163 did not correlate with C-reactive protein and leukocyte count as established markers of inflammation. Levels were not associated with disease severity assessed by the Schroeder score, Balthazar score, Acute Physiology, Age, and Chronic Health Evaluation (Apache) II score and peripancreatic necrosis score. Soluble CD163 was not related to complications of acute pancreatitis. These data show that serum sCD163 is increased in acute pancreatitis indicating activation of macrophages but is not associated with disease severity and outcome. PMID:26209500

    Full Text Available Recently soluble CD163 (sCD163, a cleaved form of the macrophage receptor CD163, was identified as a macrophage-specific risk-predictor for developing Type 2 Diabetes. Here, we investigate circulating levels of sCD163 in gestational diabetes mellitus (GDM. Furthermore, given the role of the placenta in the pathogenesis of GDM, we assessed placental contribution to sCD163 secretion. Paired maternal (venous and umbilical vein blood samples from GDM (n = 18 and Body Mass Index (BMI matched control women (n = 20 delivered by caesarean section at 39-40 week gestation were assessed for circulating levels of sCD163, Tumour necrosis factor alpha (TNF-α and Interleukin 6 (IL-6. Media from explant culture of maternal subcutaneous fat and corresponding placental tissues were assayed for these same molecules. CD163 positive cell numbers were determined in placental and adipose tissues of GDM and control women. We found significantly elevated circulating sCD163 levels in GDM mothers (688.4±46.9 ng/ml vs. 505.6±38.6 ng/ml and their offspring (418.2±26.6 ng/ml vs. 336.3±24.4 ng/ml [p<0.05 for both] as compared to controls, together with elevated circulating TNF-α and IL-6 levels. Moreover, both GDM placentae (268.1±10.8 ng/ml/mg vs. 187.6±20.6 ng/ml/mg and adipose explants (41.1±2.7 ng/ml/mg vs. 26.6±2.4 ng/ml/mg released significantly more sCD163 than controls. Lastly, significantly more CD163 positive cells were observed in GDM placentae (25.7±1.1 vs. 22.1±1.2 and adipose tissue (19.1±1.1 vs 12.7±0.9 compared to controls. We describe elevated sCD163 levels in GDM and identify human placenta as a novel source of sCD163 suggesting that placental tissues might contribute to the increased levels of circulating sCD163 in GDM pregnancies.

    Full Text Available BACKGROUND: Soluble CD163 (sCD163 is a macrophage specific protein known to be up-regulated in serum from patients with multiple sclerosis (MS. OBJECTIVE: To investigate sCD163 in serum and CSF (cerebrospinal fluid from patients undergoing MS diagnostic work-up and analyse its potential as a diagnostic biomarker. METHODS: After a full MS diagnostic work-up, including collection of paired samples of CSF and serum, 183 patients were evaluated for inclusion in this study. Patients were divided into groups based on their diagnosis. Patients with normal clinical and paraclinical findings were grouped as symptomatic controls. Serum and CSF levels of sCD163 were determined by enzyme-linked immunosorbent assay (ELISA. RESULTS: sCD163 could be measured in all serum and CSF samples. A high sCD163 CSF/serum ratio in relation to molecular weight was found, strongly indicating local production in the CNS. Median levels of sCD163 were significantly decreased in serum and significantly elevated in CSF in patients with relapsing-remitting, and primary-progressive MS. There were, however, some overlaps of the measures between groups. In a receiver operating characteristic (ROC analysis sCD163 CSF/serum ratio had an area under the curve of 0.72. CONCLUSION: The sCD163 CSF/serum ratio was significantly increased in patients with MS and may reflect macrophage activation in MS lesions. These results suggest that primary progressive MS also is driven by inflammation in which the innate immune system plays a pivotal role.

  5. Soluble CD163, a product of monocyte/macrophage activation, is inversely associated with haemoglobin levels in placental malaria.

    Directory of Open Access Journals (Sweden)

    Caroline Lin Lin Chua

    Full Text Available In Plasmodium falciparum malaria, activation of monocytes and macrophages (monocytes/macrophages can result in the production of various inflammatory mediators that contribute to immunopathology. Soluble CD163 (sCD163 is a specific marker of monocyte/macrophage activation typically found at increased levels during various inflammatory conditions and can be associated with poor clinical outcomes. To better understand the relationships between levels of sCD163 and clinical parameters in women with placental malaria, we measured plasma sCD163 levels in maternal peripheral and placental blood compartments at delivery and determined their correlations with birth weight and maternal haemoglobin concentrations. sCD163 levels were negatively correlated with birth weight only in the placental compartment (r = -0.145, p = 0.03 and were inversely correlated with maternal haemoglobin concentrations, both in peripheral blood (r = -0.238, p = 0.0004 and in placental blood (r = -0.259, p = 0.0001. These inverse relationships suggest a potential role for monocyte/macrophage activation in the pathogenesis of malaria in pregnancy, particularly in relation to malaria-associated anaemia.

    Full Text Available BACKGROUND: The diagnosis of sepsis is challenging and there is an unmet need for sensitive and specific diagnostic and prognostic biomarkers. Following activation of macrophages and monocytes, the haptoglobin-haemoglobin receptor (CD163 and the mannose receptor (MR are shed into the circulation (sCD163 and sMR. OBJECTIVE: We investigated monocyte expression of CD163 and MR, and levels of sCD163 and sMR in septic and non-septic patients, and in healthy controls. We hypothesised that these receptors are elevated during sepsis and can be used diagnostic and prognostic. METHODS: Twenty-one patients with severe sepsis or septic shock and 15 critically ill non-septic patients were included in this prospective observational study at three ICUs at Aarhus University Hospital and Randers Regional Hospital, Denmark. Fifteen age- and gender-matched healthy volunteers served as controls. Levels of sCD163 and sMR were measured using a sandwich ELISA and monocyte expression of CD163 and MR was evaluated by flow cytometry during the first four days of ICU stay. The diagnostic and prognostic values of the receptors were assessed using AUROC curves. RESULTS: At ICU admission and during the observation period, monocyte expression of CD163 and levels of sCD163 and sMR were significantly higher in septic patients compared with non-septic patients and healthy controls (p<0.01 for all comparisons. Monocytes did not express MR. The diagnostic values estimated by AUROC were 1.00 for sMR, 0.95 for sCD163, 0.87 for CRP, and 0.75 for monocyte-bound CD163. Among the septic patients, monocyte expression of CD163 was higher in non-survivors compared with survivors at ICU admission (p = 0.02 and during the observation period (p = 0.006. The prognostic value of monocyte-bound CD163 estimated by AUROC at ICU admission was 0.82. CONCLUSION: The macrophage-specific markers CD163, sCD163, and sMR are increased in septic patients. Particularly sMR is a promising new

    The haptoglobin- (Hp-) CD163-heme oxygenase-1 (HO-1) pathway is an efficient captor-receptor-enzyme system to circumvent the hemoglobin (Hb)/heme-induced toxicity during physiological and pathological hemolyses. In this pathway, Hb tightly binds to Hp leading to CD163-mediated uptake of the complex...... in macrophages followed by lysosomal Hp-Hb breakdown and HO-1-catalyzed conversion of heme into the metabolites carbon monoxide (CO), biliverdin, and iron. The plasma concentration of Hp is a limiting factor as evident during accelerated hemolysis, where the Hp depletion may cause serious Hb...... inflammation. The heme metabolites including bilirubin converted from biliverdin have overall an anti-inflammatory effect and thus reinforce the anti-inflammatory efficacy of the Hp-CD163-HO-1 pathway. Future studies of animal models of inflammation should further define the importance of the pathway in the...

  8. Inhibition of soluble epoxide hydrolase contributes to the anti-inflammatory effect of antimicrobial triclocarban in a murine model

    International Nuclear Information System (INIS)

    The increasing use of the antimicrobial triclocarban (TCC) in personal care products (PCPs) has resulted in concern regarding environmental pollution. TCC is a potent inhibitor of soluble epoxide hydrolase (sEH). Inhibitors of sEH (sEHIs) are anti-inflammatory, anti-hypertensive and cardio-protective in multiple animal models. However, the in vivo effects anticipated from a sEHI have not been reported for TCC. Here we demonstrated the anti-inflammatory effects in vivo of TCC in a murine model. TCC was employed in a lipopolysaccharide (LPS)-challenged murine model. Systolic blood pressure, plasma levels of several inflammatory cytokines and chemokine, and metabolomic profile of plasma oxylipins were determined. TCC significantly reversed LPS-induced morbid hypotension in a time-dependent manner. TCC significantly repressed the increased release of inflammatory cytokines and chemokine caused by LPS. Furthermore, TCC significantly shifted the oxylipin profile in vivo in a time-dependent manner towards resolution of inflammation as expected from a sEHI. These results demonstrated that at the doses used TCC is anti-inflammatory in the murine model. This study suggests that TCC may provide some benefits in humans in addition to its antimicrobial activities due to its potent inhibition of sEH. It may be a promising starting point for developing new low volume high value applications of TCC. However these biological effects also caution against the general over use of TCC in PCPs. - Graphical abstract: Display Omitted Research Highlights: → Anti-microbial triclocarban (TCC) is anti-inflammatory in a murine model. → TCC significantly shifted the oxylipin profile in vivo as expected from a sEHI. → TCC significantly reversed LPS-induced morbid hypotension in a time-dependent manner. → TCC significantly repressed LPS-induced increased release of inflammatory cytokines.

    Lysis of RBCs during numerous clinical settings such as severe hemolytic anemia, infection, tissue injury, or blood transfusion releases the endogenous damage-associated molecular pattern, hemoglobin (Hb), into the plasma. The redox-reactive Hb generates cytotoxic reactive oxygen species, disrupting the redox balance and impairing the immune-responsive blood cells. Therefore, it is crucial to understand how the immune system defends against the cytotoxic Hb. We identified a shortcut "capture and quench" mechanism of detoxification of Hb by the monocyte scavenger receptor CD163, independent of the well-known dominant antioxidant, haptoglobin. Our findings support a highly efficient two-pass mechanism of detoxification and clearance of Hb: 1) a direct suppression of Hb-pseudoperoxidase activity by CD163, involving an autocrine loop of CD163 shedding, sequestration of Hb, recycling, and homeostasis of CD163 in human monocytes and 2) paracrine transactivation of endothelial cells by the shedded soluble CD163 (sCD163), which further detoxifies and clears residual Hb. We showed that sCD163 and IgG interact with free Hb in the plasma and subsequently the sCD163-Hb-IgG complex is endocytosed into monocytes via FcγR. The endocytosed sCD163 is recycled to restore the homeostasis of CD163 on the monocyte membrane in an autocrine cycle, whereas the internalized Hb is catabolized. Using ex vivo coculture experiments, we demonstrated that the monocyte-derived sCD163 and IgG shuttle residual plasma Hb into the proximal endothelial cells. These findings suggest that CD163 and IgG collaborate to engage monocytes and endothelial cells in a two-pass detoxification mechanism to mount a systemic defense against Hb-induced oxidative stress.

    Macrophages play an important role in rhabdomyolysis-acute kidney injury (AKI), although the molecular mechanisms involved in macrophage differentiation are poorly understood. We analyzed the expression and regulation of CD163, a membrane receptor mainly expressed by anti-inflammatory M2 macrophages, in rhabdomyolysis-AKI and developed targeted probes for its specific detection in vivo by MRI. Intramuscular injection of glycerol in mice promoted an early inflammatory response, with elevated proportion of M1 macrophages, and partial differentiation towards a M2 phenotype in later stages, where increased CD163 expression was observed. Immunohistological studies confirmed the presence of CD163-macrophages in human rhabdomyolysis-AKI. In cultured macrophages, myoglobin upregulated CD163 expression via HO-1/IL-10 axis. Moreover, we developed gold-coated iron oxide nanoparticles vectorized with an anti-CD163 antibody that specifically targeted CD163 in kidneys from glycerol-injected mice, as determined by MRI studies, and confirmed by electron microscopy and immunological analysis. Our findings are the first to demonstrate that CD163 is present in both human and experimental rhabdomyolysis-induced AKI, suggesting an important role of this molecule in this pathological condition. Therefore, the use of probes targeting CD163-macrophages by MRI may provide important information about the cellular composition of renal lesion in rhabdomyolysis. PMID:27162559

    Full Text Available Abstract Background Macrophages have been implicated in the pathogenesis of COPD. M1 and M2 macrophages constitute subpopulations displaying pro- and anti-inflammatory properties. We hypothesized that smoking cessation affects macrophage heterogeneity in the lung of patients with COPD. Our aim was to study macrophage heterogeneity using the M2-marker CD163 and selected pro- and anti-inflammatory mediators in bronchoalveolar lavage (BAL fluid and induced sputum from current smokers and ex-smokers with COPD. Methods 114 COPD patients (72 current smokers; 42 ex-smokers, median smoking cessation 3.5 years were studied cross-sectionally and underwent sputum induction (M/F 99/15, age 62 ± 8 [mean ± SD] years, 42 (31-55 [median (range] packyears, post-bronchodilator FEV1 63 ± 9% predicted, no steroids past 6 months. BAL was collected from 71 patients. CD163+ macrophages were quantified in BAL and sputum cytospins. Pro- and anti-inflammatory mediators were measured in BAL and sputum supernatants. Results Ex-smokers with COPD had a higher percentage, but lower number of CD163+ macrophages in BAL than current smokers (83.5% and 68.0%, p = 0.04; 5.6 and 20.1 ×104/ml, p = 0.001 respectively. The percentage CD163+ M2 macrophages was higher in BAL compared to sputum (74.0% and 30.3%, p + BAL macrophages (Rs = 0.38, p = 0.003. No significant differences were found between smokers and ex-smokers in the levels of pro-inflammatory (IL-6 and IL-8, and anti-inflammatory (elafin, and Secretory Leukocyte Protease Inhibitor [SLPI] mediators in BAL and sputum. Conclusions Our data suggest that smoking cessation partially changes the macrophage polarization in vivo in the periphery of the lung towards an anti-inflammatory phenotype, which is not accompanied by a decrease in inflammatory parameters.

    Inflammation is the body's first response to infection or injury and is critical for both innate and adaptive immunity. It can be considered as part of the complex biological response of vascular tissues to harmful stimuli such as pathogens, damaged cells, or irritants. The search for natural compounds and phytoconstituents that are able to interfere with these mechanisms by preventing a prolonged inflammation could be useful for human health. Here, the anti-inflammatory properties of plant-based drugs are put together with both in vitro and acute (carrageenan, egg albumin and croton oil) and chronic (cotton pellet) in vivo models.

    The course of disease among HIV-2, HIV-1, and HIV-1/2 dually infected patients is different. We investigated the macrophage activation marker soluble CD163 (sCD163) dynamics in 212 HIV-1, HIV-2, and HIV-1/2 dually infected patients. There were no differences in sCD163 levels at baseline or during follow-up without antiretroviral therapy (ART). At follow-up on ART, median sCD163 levels were decreased for HIV-1-infected patients (P < 0.001), but not among HIV-2 (P = 0.093) or HIV-1/2 dually infected patients (P = 0.145). The larger decrease in sCD163 levels among HIV-1-infected patients during ART may indicate an HIV type-dependent differential effect of ART on macrophage activation during HIV infection.

    Full Text Available Abstract Background Sepsis is a common syndrome in critically ill patients and easily leads to the occurrence of acute kidney injury (AKI, with high mortality rates. This study aimed to investigate the diagnostic value of urine soluble CD163 (sCD163 for identification of sepsis, severity of sepsis, and for secondary AKI, and to assess the patients’ prognosis. Methods We enrolled 20 cases with systemic inflammatory response syndrome (SIRS, 40 cases with sepsis (further divided into 17 sepsis cases and 23 severe sepsis cases admitted to the intensive care unit (ICU, and 20 control cases. Results for urine sCD163 were recorded on the day of admission to the ICU, and AKI occurrence was noted. Results On the day of ICU admission, the sepsis group exhibited higher levels of urine sCD163 (74.8 ng/ml; range: 47.9-148.3 ng/ml compared with those in the SIRS group (31.9 ng/ml; 16.8-48.0, P . The area under the curve (AUC was 0.83 (95% confidence interval [CI]: 0.72-0.94, P  the sensitivity was 0.83, and the specificity was 0.75 (based on a cut-off point of 43.0 ng/ml. Moreover, the severe sepsis group appeared to have a higher level of sCD163 compared with that in the sepsis group (76.2; 47.2-167.5 ng/ml vs. 74.2; 46.2-131.6 ng/ml, but this was not significant. For 15 patients with AKI, urine sCD163 levels at AKI diagnosis were significantly higher than those of the remaining 35 sepsis patients upon ICU admission (121.0; 74.6-299.1 ng/ml vs. 61.8; 42.8-128.3 ng/ml, P = 0.049. The AUC for urine sCD163 was 0.688 (95% CI: 0.51-0.87, P = 0.049. Sepsis patients with a poor prognosis showed a higher urine sCD163 level at ICU admission (98.6; 50.3-275.6 ng/ml vs. 68.0; 44.8-114.5 ng/ml, but this was not significant. Patients with AKI with a poor prognosis had higher sCD163 levels than those in patients with a better prognosis (205.9; 38.6-766.0 ng/ml vs. 80.9; 74.9-141.0 ng/ml, but this was not significant. Conclusions This study shows, for the

    Full Text Available In inflammatory diseases, macrophages are a main producer of a range of cytokines regulating the inflammatory state. This also includes inflammation induced by tumor growth, which recruits so-called tumor-associated macrophages supporting tumor growth. Macrophages are therefore relevant targets for cytotoxic or phenotype-modulating drugs in the treatment of inflammatory and cancerous diseases. Such targeting of macrophages has been tried using the natural propensity of macrophages to non-specifically phagocytose circulating foreign particulate material. In addition, the specific targeting of macrophage-expressed receptors has been used in order to obtain a selective uptake in macrophages and reduce adverse effects of off-target delivery of drugs. CD163 is a highly expressed macrophage-specific endocytic receptor that has been studied for intracellular delivery of small molecule drugs to macrophages using targeted liposomes or antibody drug conjugates. This review will focus on the biology of CD163 and its potential role as a target for selective macrophage targeting compared with other macrophage targeting approaches.

    Full Text Available Abstract Background The scavenger receptor cysteine rich (SRCR domain is an ancient and conserved protein domain. CD163 and WC1 molecules are classed together as group B SRCR superfamily members, along with Spα, CD5 and CD6, all of which are expressed by immune system cells. There are three known types of CD163 molecules in mammals, CD163A (M130, coded for by CD163, CD163b (M160, coded for by CD163L1 and CD163c-α (CD163L1 or SCART, while their nearest relative, WC1, is encoded by a multigene family so far identified in the artiodactyl species of cattle, sheep, and pigs. Results We annotated the bovine genome and identified genes coding for bovine CD163A and CD163c-α but found no evidence for CD163b. Bovine CD163A is widely expressed in immune cells, whereas CD163c-α transcripts are enriched in the WC1+ γδ T cell population. Phylogenetic analyses of the CD163 family genes and WC1 showed that CD163c-α is most closely related to WC1 and that chicken and platypus have WC1 orthologous genes, previously classified as among their CD163 genes. Conclusion Since it has been shown that WC1 plays an important role in the regulation of γδ T cell responses in cattle, which, like chickens, have a high percentage of γδ T cells in their peripheral blood, CD163c-α may play a similar role, especially in species lacking WC1 genes. Our results suggest that gene duplications resulted in the expansion of CD163c-α-like and WC1-like molecules. This expanded repertoire was retained by species known as "γδ T cell high", but homologous SRCR molecules were maintained by all mammals.

    Full Text Available OBJECTIVE: To test the usefulness of serum concentrations of tumor necrosis factor-like weak inducer of apoptosis (sTWEAK and soluble scavenger receptor CD163 (sCD163 as markers of subtle inflammation in patients with type 1 diabetes mellitus (T1DM without clinical cardiovascular (CV disease and to evaluate their relationship with arterial stiffness (AS. METHODS: Sixty-eight patients with T1DM and 68 age and sex-matched, healthy subjects were evaluated. Anthropometrical variables and CV risk factors were recorded. Serum concentrations of sTWEAK and sCD163 were measured. AS was assessed by aortic pulse wave velocity (aPWV. All statistical analyses were stratified by gender. RESULTS: T1DM patients showed lower serum concentrations of sTWEAK (Men: 1636.5 (1146.3-3754.8 pg/mL vs. 765.9 (650.4-1097.1 pg/mL; p<0.001. Women: 1401.0 (788.0-2422.2 pg/mL vs. 830.1 (562.6-1175.9 pg/mL; p = 0.011 compared with their respective controls. Additionally, T1DM men had higher serum concentrations of sCD163 (285.0 (247.7-357.1 ng/mL vs. 224.8 (193.3-296.5 ng/mL; p = 0.012 compared with their respective controls. sTWEAK correlated negatively with aPWV in men (r = -0.443; p<0.001. However, this association disappeared after adjusting for potential confounders. In men, the best multiple linear regression model showed that the independent predictors of sTWEAK were T1DM and WHR (R(2 = 0.640; p<0.001. In women, T1DM and SBP were the independent predictors for sTWEAK (R(2 = 0.231; p = 0.001. CONCLUSION: sTWEAK is decreased in T1DM patients compared with age and sex-matched healthy subjects after adjusting for classic CV risk factors, although sTWEAK levels may be partially influenced by some of them. Additionally, T1DM men have higher serum concentrations of sCD163. These results point out an association between the inflammatory system and CV risk in T1DM.

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.

    CD163 and sialoadhesin (SN) were reported as two essential receptors for the porcine reproductive and respiratory syndrome virus. To investigate the relationship between these two genes and porcine immunity, we assigned porcine CD163 and SN respectively to SSC5q21-q24 and SSC17q23 by IMpRH. Expression profiles revealed that CD163 and SN were ubiquitously expressed in ten tissues, and were expressed highly in lymph gland, spleen and liver, which implied the potential functions of CD163 and SN in immunity. Moreover, a single nucleotide polymorphism (SNP) c.3534C>T was found in 3'-UTR of the CD163 gene and association analysis showed that this gene was significantly associated with the IgG content in blood (P G located in exon4 of the SN gene which caused the amino acid transition from histidine to arginine was detected, and it was significantly associated with the WBC count in the peripheral blood (P < 0.05). These results provided fundamental evidence for CD163 and SN as two functional candidate genes affecting immunity in pigs. PMID:21786159

    1. The effect of liposome phospholipid composition has been assumed to be relatively unimportant because of the presumed inert nature of phospholipids. 2. We have previously shown that cationic liposome formulations used for gene therapy inhibit, through their cationic component, the synthesis by activated macrophages of the pro-inflammatory mediators nitric oxide (NO) and tumour necrosis factor-alpha (TNF-alpha). 3. In this study, we have evaluated the ability of different cationic lipids to reduce footpad inflammation induced by carrageenan and by sheep red blood cell challenge. 4. Parenteral (i.p. or s.c) or local injection of the positively charged lipids dimethyldioctadecylammomium bromide (DDAB), dioleyoltrimethylammonium propane (DOTAP), dimyristoyltrimethylammonium propane (DMTAP) or dimethylaminoethanecarbamoyl cholesterol (DC-Chol) significantly reduced the inflammation observed in both models in a dose-dependent manner (maximum inhibition: 70-95%). 5. Cationic lipids associated with dioleyol- or dipalmitoyl-phosphatidylethanolamine retained their anti-inflammatory activity while cationic lipids associated with dipalmitoylphosphatidylcholine (DPPC) or dimyristoylphosphatidylglycerol (DMPG) showed no anti-inflammatory activity, indicating that the release of cationic lipids into the macrophage cytoplasm is a necessary step for anti-inflammatory activity. The anti-inflammatory activity of cationic lipids was abrogated by the addition of dipalmitoylphosphatidylethanolamine-poly(ethylene)glycol-2000 (DPPE-PEG2000) which blocks the interaction of cationic lipids with macrophages. 6. Because of the significant role of protein kinase C (PKC) in the inflammatory process we have determined whether the cationic lipids used in this study inhibit PKC activity. The cationic lipids significantly inhibited the activity of PKC but not the activity of a non-related protein kinase, PKA. The synthesis of interleukin-6 (IL-6), which is not dependent on PKC activity for its

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.

    Cryptolepine is the major alkaloid of the West African shrub, Cryptolepis sanguinolenta. Cryptolepine has been shown to inhibit nitric oxide production, and DNA binding of Nuclear Factor-kappa B following inflammatory stimuli in vitro. In order to validate the anti-inflammatory property of this compound in vivo, we investigated its effects on a number of animal models of inflammation. Cryptolepine (10-40 mg/kg i.p.) produced significant dose-dependent inhibition of the carrageenan-induced rat paw oedema, and carrageenan-induced pleurisy in rats. These effects were compared with those of the non-steroidal anti-inflammatory drug indomethacin (10 mg/kg). At doses of 10-40 mg/kg i.p., cryptolepine inhibited lipopolysaccharide (LPS)-induced microvascular permeability in mice in a dose-related fashion. Oral administration of up to 40 mg/kg of the compound for four consecutive days did not induce gastric lesion formation in rats. Analgesic activity was also exhibited by cryptolepine through a dose-related (10-40 mg/kg i.p.) inhibition of writhing induced by i.p. administration of acetic acid in mice. The results of this study reveal that cryptolepine possesses in vivo anti-inflammatory activity. PMID:19288476

    Expression of the macrophage antigen CD163 in breast cancer cells is recently shown to be related to early distant recurrence and shortened survival. In this study, 163 patients with rectal cancer, included in the Swedish rectal cancer trial and followed up for a median of 71 months, were examined for the expression of CD163 in the primary tumors. The cancer cells expressed CD163 in the primary tumors in 23% (n = 32) of the patients. In pretreatment biopsies from 101 patients, 10 had CD163-positive cancers and these patients had earlier local recurrence (p CD163-negative tumors. When studying surgical specimens from 61 patients randomized to preoperative irradiation (5 x 5 Gy delivered in 1 week), it was found that 31% were CD163 positive whereas the corresponding figure was only 17% for 78 patients who were nonirradiated (p CD163-positive tumors there was a reduced apoptotic activity as measured with the Termina deoxynucleotidyl Transferase Biotin-dUTP Nick End Labeling (TUNEL) technique (p = 0.018). There tended also to be an increased proliferation activity measured as an expression of Ki-67 non significant (NS). It is concluded that primary rectal cancers may express CD-163, and this phenotypic macrophage trait is related to early local recurrence, shorter survival time and reduced apoptosis. Furthermore, the expression of CD163 is more common after irradiation. PMID:19582880

  12. Erdosteine: antitussive and anti-inflammatory effects.

    Science.gov (United States)

    Dal Negro, Roberto W

    2008-01-01

    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.

    Full Text Available Tumor-associated macrophages (TAMs play an important role in the progression and prognostication of numerous cancers. However, the role and clinical significance of TAM markers in oral squamous cell carcinoma (OSCC has not been elucidated. The present study was designed to investigate the correlation between the expression of TAM markers and pathological features in OSCC by tissue microarray. Tissue microarrays containing 16 normal oral mucosa, 6 oral epithelial dysplasia, and 43 OSCC specimens were studied by immunohistochemistry. We observed that the protein expression of the TAM markers CD68 and CD163 as well as the cancer stem cell (CSC markers ALDH1, CD44, and SOX2 increased successively from the normal oral mucosa to OSCC. The expressions of CD68 and CD163 were significantly associated with lymph node status, and SOX2 was significantly correlated with pathological grade and lymph node status, whereas ALDH1 was correlated with tumor stage. Furthermore, CD68 was significantly correlated with CD163, SOX2, and ALDH1 (P<0.05. Kaplan-Meier analysis revealed that OSCC patients overexpressing CD163 had significantly worse overall survival (P<0.05. TAM markers are associated with cancer stem cell marker and OSCC overall survival, suggesting their potential prognostic value in OSCC.

    The cell population of peripheral blood monocytes/macrophages (MO) is heterogeneous: The majority of the MO are CD14++ CD16- and named "classical" (= MO1). Furthermore, two other subpopulations were described: CD14++ CD16+ ("intermediate" = MO2) and CD14+ CD16++ ("non-classical" = MO3). It is reported that MO2 possess anti-inflammatory properties and express the MO lineage marker CD163. On a hydrophilic neutrally charged acrylamide-based hydrogel human intermediate (CD14++ CD16+ ), angiogenically stimulated CD163++ monocytes/macrophages (aMO2) maintained a proangiogenic and noninflammatory status for at least 14 days. Here, we explored whether this aMO2 subset adhered to hydrophobic poly(n-butyl acrylate) networks (cPnBA) and also remained in its proangiogenic and noninflammatory status. Because substrate elasticity can impact adherence, morphology, and function of cells, cPnBAs with different Young's modulus (250 and 1100 kPa) were investigated, whereby their elasticity was tailored by variation of the cross-linker content and matched to the elasticity of human arteries. The cPnBAs exhibited similar surface properties (e.g., surface roughness), which were maintained after ethylene oxide sterilization and exposure in serum-free cell culture medium for 18 h at 37°C. aMO2 were seeded on cPnBA samples (1.7 × 10(5) cells/1.33 cm(2) ) in Dulbecco's modified Eagle medium (DMEM high glucose) supplemented with vascular endothelial growth factor 165 (VEGF-A(165) , 10 ng/mL) and fetal calf serum (10 vol%) for 3 and 72 h. On both polymeric samples (n = 3 each), the numbers of adherent cells per unit area were significantly higher (P < 0.01; cPnBA0250: 3 h 13 ± 5 cells/mm(2) , 72 h 234 ± 106 cells/mm(2) ; cPnBA1100: 3 h 14 ± 3 cells/mm(2) , 72 h 198 ± 113 cells/mm(2) ) compared to control cultures (glass, 3 h: 6 ± 3 cells/mm(2) , 72 h: 130 ± 83 cells/mm(2) ) and showed a typically spread morphology.

    The purpose of this study was to modulate macrophage polarity from the pro-inflammatory M1 to anti-inflammatory M2 phenotype using plasmid DNA (pDNA) expressing interleukin-4 (IL4) or interleukin-10 (IL10)-encapsulated in hyaluronic acid-poly(ethyleneimine) (HA-PEI) nanoparticles (NPs). The HA-PEI/pDNA NPs with spherical shape, average size of 186 nm were efficiently internalized by J774A.1 macrophages. Transfection of HA-PEI/pDNA-IL4 and HA-PEI/pDNA-IL10 NPs increased IL4 and IL10 gene expression in J774 macrophages which could re-program the macrophages from M1 to M2 phenotype as evidenced by a significant increase in the Arg/iNOS level, and upregulation of CD206 and CD163 compared to untreated macrophages. Following intraperitoneal (IP) injection to C57BL/6 mice, HA-PEI NPs effectively targeted peritoneal macrophages over-expressing CD44 receptor. In an in vivo model of stimulated peritoneal macrophages, IP administration of HA-PEI/pDNA-IL4 and HA-PEI/pDNA-IL10 to C57BL/6 mice significantly increased the Arg/iNOS ratio and CD163 expression in the cells. Furthermore, HA-PEI/pDNA-IL10 NPs significantly increased peritoneal and serum IL10 levels which effectively suppressed LPS-induced inflammation by reducing level of TNF-α and IL-1β in peritoneal macrophages and in the peritoneal fluid. The results demonstrated that pDNA-IL10-encapsulate HA-PEI NPs skewed macrophage functional polarity from M1 toward an anti-inflammatory M2 phenotype which may be a promising platform for the treatment of inflammatory diseases.

    The study of plants used in traditional medicine has drawn the attention of researchers as an alternative in the development of new therapeutics agents, such as the American Solanaceae Physalis peruviana, which has significant anti-inflammatory activity. The Physalis peruviana anti-inflammatory effect of ethanol or ether calyces extracts on the phagocytic process was assessed by using an in vitro phagocytosis model (Leishmania panamensis infection to murine macrophages). The Physalis peruviana extracts do not inhibit microorganism internalization and have no parasiticide effect. Most ET and EP extracts negatively affected the parasite's invasion of macrophages (Infected cells increased.). This observation might result from a down-regulation of the macrophage's microbicide ability associated with a selective reduction of proinflammatory cytokines levels. Physalis peruviana's anti-inflammatory activity described in this model is related to an immunomodulatory effect exerted on macrophages infected, which directly or indirectly "blocks" their ability to secrete soluble proinflammatory mediators.

    Objective: To evaluate the anti-inflammatory and analgesic activities of leaf extract of Melanthera scandens (M. scandens). Methods: The crude leaf extract (39-111 mg/kg) of M. scandens was investigated for anti-inflammatory and analgesic activities using various experimental models. The anti-inflammatory activity was investigated using carragenin, egg-albumin induced oedema models, while acetic acid, formalin-induced paw licking and thermal-induced pain models were used to evaluate the antinociceptive property. Results: The extract caused a significant (P<0.05 - 0.001) dose-dependent reduction of inflammation and pains induced by different agents used. Conclusions: The leaf extract possesses anti-inflammatory and analgesic effects which may be mediated through the phytochemical constituents of the plant.

    Several routes of porcine reproductive and respiratory virus PRRSV transmission across the porcine diffuse epitheliochorial placentation have been proposed, but none have been proven. The objectives of this study were to investigate associations between numbers of CD163 and CD169 positive macrophages, cathepsin positive areolae, and type 2 PRRSV load at the maternal-fetal interface in order to examine important factors related to transplacental infection. On gestation day 85 ± 1, naïve pregnant gilts were inoculated with PRRSV (n = 114) or were sham inoculated (n = 19). At 21 days post-inoculation (dpi), dams and their litters were humanely euthanized and necropsied. Samples of the maternal-fetal interface (uterus with fully attached placenta) and fetal thymus were collected for analysis by RT-qPCR to quantify PRRSV RNA concentration. The corresponding paraffin-embedded uterine tissue sections were subjected to immunohistochemistry for PRRSV nucleocapsid N protein, CD163, CD169, and cathepsin. Our findings confirm significant increases in the numbers of PRRSV, CD163 and CD169 positive cells at the maternal-fetal interface during type 2 PRRSV infection in pregnant gilts. PRRSV load in fetal thymus was positively related to CD163(+) cell count in endometrium and negatively related to CD163(+) cell count in placenta, but unrelated to CD169 counts or cathepsin positive areolae. The endometrium:placenta ratio of CD163 cells, and to a lesser extent CD169 cells, was significantly associated with an increase fetal viral load in thymus. These findings suggest a more important role for CD163(+) cells following trans-placental PRRSV infection, but dichotomous responses in endometrium and placenta for both CD163 and CD169 cells.

    Full Text Available Objective. To evaluate the expression of CD64 and CD163 on neutrophils and monocytes in SIRS with/without sepsis and to compare the diagnostic accuracy of CD64 and CD163 molecules expression determined as (1 mean fluorescence intensities (MFI of CD64 and CD163; and (2 the ratio (index of linearized MFI to the fluorescence signal of standardized beads. Patients and methods. Fifty-six critically ill neonates and children with systemic inflammatory response syndrome (SIRS and suspected sepsis, classified into two groups: SIRS with sepsis (n=29 and SIRS without sepsis (n=27. Results. CD64 and CD163 MFI measured on neutrophils and monocytes were elevated in patients with SIRS with sepsis. Diagnostic accuracy of indexes was equal to diagnostic accuracy of MFI for CD64 on neutrophils (0.833 versus 0.854 for day 0 and 0.975 versus 0.983 for day 1 and monocytes (0.811 versus 0.865 for day 0 and 0.825 versus 0.858 for day 1, and CD163 on neutrophils (0.595 versus 0.655 for day 0 and 0.677 versus 0.750 for day 1, but not for CD163 on monocytes. Conclusion. CD64 MFI, CD163 MFI, CD64 indexes for neutrophils and monocytes, and CD163 index for neutrophils can all be used for discrimination of SIRS and sepsis in critically ill neonates and children. CD64 index for neutrophils, however, is superior to all other markers.

    Compounds that combine metal-based drugs with covalently linked targeted organic agents have been shown, in some instances, to exhibit superior anticancer properties compared to the individual counterparts.

The NSAIDs are attached to the organometallic moieties via monodentate (pyridine/phosphine) or bidentate (bipyridine) ligands, affording piano-stool Ru(II) and Os(II) arene complexes of general formula [M(η(6)-p-cymene)Cl2(N)], where N is a pyridine-based ligand, {2-(2-(1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-yl)acetoxy)ethyl-3-(pyridin-3-yl)propanoate} or {2-(2-(2-((2,6-dichlorophenyl)amino)phenyl)acetoxy)ethyl-3-(pyridin-3-yl)propanoate}, [M(η(6)-p-cymene)Cl2(P)], where P is a phosphine ligand, {2-(2-(1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-yl)acetoxy)ethyl-4-(diphenylphosphanyl)benzoate} or {2-(2-(2-((2,6-dichlorophenyl)amino)phenyl)acetoxy)ethyl-4-(diphenylphosphanyl)benzoate, and [M(η(6)-p-cymene)Cl(N,N')][Cl], where N,N' is a bipyridine-based ligand, (4'-methyl-[2,2'-bipyridin]-4-yl)methyl-2-(1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-yl)acetate), (4'-methyl-[2,2'-bipyridin]-4-yl)methyl-2-(2-((2,6-dichlorophenyl)amino)phenyl)acetate), (bis(2-(2-(1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-yl)acetoxy)ethyl)[2,2'-bipyridine]-5,5'-dicarboxylate), or (bis(2-(2-(2-((2,6-dichlorophenyl)amino)phenyl)acetoxy)ethyl)[2,2'-bipyridine]-5,5'-dicarboxylate). The antiproliferative properties of the complexes were assessed in human ovarian cancer cells (A2780 and A2780cisR, the latter being resistant to cisplatin) and nontumorigenic human embryonic kidney (HEK-293) cells. Some of the complexes are considerably more cytotoxic than the original drugs and also display significant cancer cell selectivity. PMID:26824462

    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.

    Porphyrins are natural compounds with several biological activities. We report the synthesis and the evaluation of the anti-inflammatory and antinociceptive effects of 4 porphyrins: 5,10,15,20-tetraphenylporphyrin (TPP), 5,10,15,20-tetra(4'-fluorophenyl)porphyrin (TpFPP), 5,10,15,20-tetra(4'-chlorophenyl)porphyrin (TpClPP), and 5,10,15,20-tetra(4'-bromophenyl)porphyrin (TpBrPP). The in vitro anti-inflammatory effects were evaluated on heat-induced hemolysis. The antinociceptive effects were evaluated using the hot plate and formalin tests. The in vivo anti-inflammatory assays were tested on the acute and chronic TPA (12-O-tetradecanoylphorbol 13-acetate) method to induce ear edema. The anti-arthritic effects were evaluated using carrageenan kaolin induced arthritis (CKIA). All porphyrins inhibited hemolysis with similar potency than naproxen (NPX). In the antinociceptive tests, all porphyrins tested at 200mg/kg showed similar effects compared to 100mg/kg NPX. In the in vivo anti-inflammatory acute assay, only three porphyrins (TPP, TpFPP and TpBrPP) decreased inflammation with similar activity than 2mg/ear indomethacin (IND). Further anti-inflammatory experiments were carried out with TPP, TpFPP and TpBrPP. In the in vivo anti-inflammatory chronic assay, porphyrins decreased inflammation with similar activity than 8mg/kg IND. Porphyrins tested at 200mg/kg showed anti-arthritic effects. The antinociceptive, anti-inflammatory and arthritic activities of porphyrins suggest that these compounds might be a good alternative for the treatment of inflammatory diseases. PMID:25863493

    Full Text Available Abstract Acute and chronic tendon injuries are very common among athletes and in sedentary population. Most physicians prescribe anti-inflammatory managements to relieve the worst symptoms of swelling and pain, including non-steroidal anti-inflammatory drugs, corticosteroids and physical therapies. However, experimental research shows that pro-inflammatory mediators such as prostaglandins may play important regulatory roles in tendon healing. Noticeably nearly all cases of chronic tendon injuries we treat as specialists have received non-steroidal anti-inflammatory drugs by their physician, suggesting that there might be a potential interaction in some of these cases turning a mild inflammatory tendon injury into chronic tendinopathy in predisposed individuals. We are aware of the fact that non-steroidal anti-inflammatory drugs and corticosteroids may well have a positive effect on the pain control in the clinical situation whilst negatively affect the structural healing. It follows that a comprehensive evaluation of anti-inflammatory management for tendon injuries is needed and any such data would have profound clinical and health economic importance.

    Full Text Available Objective: The objective of the study is to evaluate the acute and chronic anti-inflammatory activities of root extract of Alpinia galanga in rodents. Materials and Methods: The study was carried out using albino rats of either sex (150-200 g. An extract of the root of A. galanga was prepared using absolute alcohol and distillation in a Soxhlet apparatus. The acute anti-inflammatory effects of this extract were evaluated using carrageenan-, bradykinin-, and 5-HT-induced rat paw edema. The chronic anti-inflammatory effects were evaluated using formaldehyde-induced rat paw edema. Results and Analysis: Inhibition of inflammation was seen to be 32.22% in carrageenan-induced, 37.70% in 5-HT-induced, and 35.21% in bradykinin-induced anti-inflammatory models. In chronic inflammatory model, a progressive inhibition of 34.73% (3 rd day, 37.50% (5 th day, 38.83% (7 th day, 44.66% (9 th day, 49.59% (11 th day, and 55.75% (13 th day was observed with study compound. The efficacy was comparable with the standard drugs. Conclusion: It can be thus concluded that A. galanga has anti-inflammatory properties and probably acts by blocking histaminic and serotonin pathways. It may be an effective alternative to NASAIDs and corticosteroid in inflammatory disorders.

  13. IL-35 is a novel responsive anti-inflammatory cytokine--a new system of categorizing anti-inflammatory cytokines.

    Xinyuan Li

    Full Text Available 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.

    This report describes the isolation and characterization of kalanchosine dimalate (KMC), an anti-inflammatory salt from the fresh juice of the aerial parts of Kalanchoe brasiliensis. KMC comprises the new metabolite kalanchosine (1) and malic acid (2) in a 1:2 stoichiometric ratio. Kalanchosine (1), 3,6-diamino-4,5-dihydroxyoctanedioic acid, is the first naturally occurring dimeric bis(gamma-hydroxy-beta-amino acid) and is at least partially responsible for the anti-inflammatory properties of K. brasiliensis.

    Full Text Available PURPOSE: We investigated whether serum interleukin (IL-8 reflects the tumor microenvironment and has prognostic value in patients with oral squamous cell carcinoma (OSCC. EXPERIMENTAL DESIGN: Fifty OSCC patients who received radical resection of their tumor(s were enrolled. Preoperative sera were measured for IL-8 by ELISA. Expression of IL-8 and the infiltration of immune cells in tumor tissues were analyzed by an immunohistochemical staining of surgical specimens. RESULTS: We found that disease-free survival (DFS was significantly longer in the Stage I/II OSCC patients with low serum IL-8 levels compared to those with high levels (p = 0.001. The tumor expression of IL-8, i.e., IL-8(T and the density of CD163-positive cells in the tumor invasive front, i.e., CD163(IF were correlated with the serum IL-8 level (p = 0.033 and p = 0.038, respectively, and they were associated with poor clinical outcome (p = 0.007 and p = 0.002, respectively, in DFS in all patients. A multivariate analysis revealed that N status, IL-8(T and CD163(IF significantly affected the DFS of the patients. Further analysis suggested that combination of N status with serum IL-8, IL-8(T or CD163(IF may be a new criterion for discriminating between OSCC patients at high and low risk for tumor relapse. Interestingly, the in vitro experiments demonstrated that IL-8 enhanced generation of CD163-positive M2 macrophages from peripheral blood monocytes, and that the cells produced IL-10. CONCLUSIONS: These findings indicate that IL-8 may be involved in poor clinical outcomes via generation of CD163-positive M2 macrophages, and that these factors in addition to N status may have prognostic value in patients with resectable OSCSS.

    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 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

    Camellia japonica oil (CJ oil) has been used traditionally in East Asia to nourish and soothe the skin as well as help restore the elasticity of skin. CJ oil has also been used on all types of bleeding instances. However, little is known about its anti-inflammatory effects. Therefore, the anti-inflammatory effects of CJ oil and its mechanisms of action were investigated. CJ oil inhibited LPS-induced production of NO, PGE(2), and TNF-α in RAW264.7 cells. In addition, expression of COX-2 and iNOS genes was reduced. To evaluate the mechanism of the anti-inflammatory activity of CJ oil, LPS-induced activation of AP-1 and NF-κB promoters was found to be significantly reduced by CJ oil. LPS-induced phosphorylation of IκBα, ERK, p38, and JNK was also attenuated. Our results indicate that CJ oil exerts anti-inflammatory effects by downregulating the expression of iNOS and COX-2 genes through inhibition of NF-κB and AP-1 signaling.

    Heparin, a glycosaminoglycan (GAG), has both anti-inflammatory and anti-coagulant properties. The clinical use of heparin against inflammation, however, has been limited by concerns about increased bleeding. While the anti-coagulant activity of heparin is well understood, its anti-inflammatory properties are less so. Heparin is known to bind to certain cytokines, including chemokines, small proteins which mediate inflammation through their control of leukocyte migration and activation. Molecules which can interrupt the chemokine-GAG interaction without inhibiting coagulation could therefore, represent a new class of anti-inflammatory agents. In the present study, two approaches were undertaken, both focusing on the heparin-chemokine relationship. In the first, a structure based strategy was used: after an initial screening of potential small molecule binders using protein NMR on a target chemokine, binding molecules were optimized through structure-based design. In the second approach, commercially available short oligosaccharides were polysulfated. In vitro, these molecules prevented chemokine-GAG binding and chemokine receptor activation without disrupting coagulation. However, in vivo, these compounds caused variable results in a murine peritoneal recruitment assay, with a general increase of cell recruitment. In more disease specific models, such as antigen-induced arthritis and delayed-type hypersensitivity, an overall decrease in inflammation was noted, suggesting that the primary anti-inflammatory effect may also involve factors beyond the chemokine system.

    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.

  4. The present status of anti-inflammatory agents in dermatology.

    Science.gov (United States)

    Stüttgen, G

    1988-01-01

    Many classes of drugs exert anti-inflammatory activity through mechanisms which affect all or part of the inflammatory process. Some of these agents are beneficial in the practice of dermatology, while others, such as penicillamine, mast cell blockers and serotonin antagonists, find little or no application. Corticosteroids, for example, are nonspecific in their anti-inflammatory effects and remain a mainstay of therapy, despite their side effect profile. Other drugs, such as the non-steroidal anti-inflammatory agents or gold, can be used in the treatment of diseases associated with rheumatic or autoimmune states. Moreover, antihistamines play an important role in the control of itching, but are mainly indicated in controlling non-dermatological allergic sequelae. Interestingly, chloroquine and dapsone, which were originally developed for use in malaria prophylaxis and leprosy, respectively, have value in treating a wide range of dermatological conditions via mechanisms which include the inhibition of P-450 isoenzymes. In diseases characterised by disturbed cornification (e.g. psoriasis pustulosa), retinoids are of particular value. These drugs are thought to act by inhibition of collagenases, proteases and granulocyte migration. Undoubtedly, further investigation of drug classes such as oxygen radical controllers and immunomodulators will clarify their mechanisms and establish their therapeutic usefulness among the anti-inflammatory agents now available for dermatological use.

    This work aimed at improving the solubility of curcumin by the preparation of spray-dried ternary solid dispersions containing Gelucire®50/13-Aerosil® and quantifying the resulting in vivo oral bioavailability and anti-inflammatory activity. The solid dispersion containing 40% of curcumin was characterised by calorimetry, infrared spectroscopy and X-ray powder diffraction. The solubility and dissolution rate of curcumin in aqueous HCl or phosphate buffer improved up to 3600- and 7.3-fold, respectively. Accelerated stability test demonstrated that the solid dispersion was stable for 9 months. The pharmacokinetic study showed a 5.5-fold increase in curcumin in rat blood plasma when compared to unprocessed curcumin. The solid dispersion also provided enhanced anti-inflammatory activity in rat paw oedema. Finally, the solid dispersion proposed here is a promising way to enhance curcumin bioavailability at an industrial pharmaceutical perspective, since its preparation applies the spray drying, which is an easy to scale up technique. The findings herein stimulate further in vivo evaluations and clinical tests as a cancer and Alzheimer chemoprevention agent. PMID:26040724

    Two different types of hyaluronic acid (HA) hydrogels were synthesized by crosslinking HA with divinyl sulfone (DVS) and poly(ethylene glycol)-divinyl sulfone (VS-PEG-VS). Vitamin E succinate (VES), an anti-inflammatory drug, and bovine serum albumin (BSA), a model of anti-inflammatory protein drugs, were loaded into the gels and their release kinetics were measured in vitro. VES and BSA released with a burst from both HA hydrogels during the first few hours, and release continued gradually for several days. The rate of release from HA-VS-PEG-VS-HA hydrogels was faster than that from HA-DVS-HA hydrogels, presumably due to the lower crosslink density in the former. The anti-inflammatory action of released VES was tested by incubating peripheral blood mononuclear cells (PBMC) on HA hydrogels with and without VES in the gel. The number of cells adhering on HA hydrogels was very low compared to that on tissue culture polystyrene (TCPS), which might be one of the important advantages of using HA hydrogels for implant coatings or tissue engineering applications. ELISA test results showed that the tumor necrosis factor-alpha (TNF-alpha) concentration was very low in the supernatant of the wells containing the HA hydrogel with VES in contact with the activated macrophages compared to that without VES. This is probably the effect of the released VES reducing the production of anti-inflammatory cytokine, TNF-alpha. HA hydrogels containing anti-inflammatory drugs may have potential for use in tissue engineering and also as biocompatible coatings of implants. PMID:15503629

    The sequencing of the bovine genome and development of mass spectrometry, in conjunction with flow cytometry (FC), have afforded an opportunity to complete the characterization of the specificity of monoclonal antibodies (mAbs), only partially characterized during previous international workshops focused on antibody development for livestock (1991, Leukocyte Antigens in Cattle, Sheep, and Goats; 1993, Leukocyte Antigens of Cattle and Sheep; 1996, Third Workshop on Ruminant Leukocyte Antigens). The objective of this study was to complete the characterization of twelve mAbs incompletely characterized during the workshops that reacted with molecules predominantly expressed on bovine monocytes and use them to provide further information on the phenotypic complexity of monocyte subsets in ruminants. Analysis revealed that the mAbs could be grouped into three clusters that recognize three different molecules: CD11c, CD14, and CD163. Following characterization, comparison of the patterns of expression of CD14 and CD163 with expression of CD16, CD172a, and CD209 revealed the mononuclear cell population is comprised of multiple subsets with differential expression of these molecules. Further analysis revealed the epitopes recognized by mAbs to CD14 and CD163 are conserved on orthologues in sheep and goats. In contrast to CD14 that is also expressed on sheep and goat granulocytes, CD163 is a definitive marker for their monocytes. PMID:27496743

    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. PMID:7879695

    Full Text Available The chemical study of Roldana platanifolia led to the isolation of β-caryophyllene, five eremophilanolides, chlorogenic acid, and a mixture of β-sitosterol-stigmasterol, β-sitosteryl glucopyranoside, and sucrose. The anti-inflammatory activities of the extracts and isolated products were tested using the 12-O-tetradecanoylphorbol-13-acetate (TPA model of induced acute inflammation. The acetone and methanol extracts showed dose dependent activities (ID50 0.21 and 0.32 mg/ear, respectively, while none of the isolated compounds exhibited relevant edema inhibition. The active extracts were also evaluated with the myeloperoxidase assay technique (MPO to determine their ability to prevent neutrophil infiltration. Results showed that the anti-inflammatory activity was related to the compound’s ability to inhibit pro-inflammatory mediators such as neutrophils.

    Full Text Available Abstract Background Porcine reproductive and respiratory syndrome virus (PRRSV causes major economic losses in the pig industry worldwide. In vivo, the virus infects a subpopulation of tissue macrophages. In vitro, PRRSV only replicates in primary pig macrophages and African green monkey kidney derived cells, such as Marc-145. The latter is currently used for vaccine production. However, since virus entry in Marc-145 cells is different compared to entry in primary macrophages, specific epitopes associated with virus entry could potentially alter upon growth on Marc-145 cells. To avoid this, we constructed CHO and PK15 cell lines recombinantly expressing the PRRSV receptors involved in virus entry into macrophages, sialoadhesin (Sn and CD163 (CHOSn-CD163 and PK15Sn-CD163 and evaluated their potential for production of PRRSV. Results Detailed analysis of PRRSV infection revealed that LV and VR-2332 virus particles could attach to and internalize into the CHOSn-CD163 and PK15Sn-CD163 cells. Initially, this occurred less efficiently for macrophage grown virus than for Marc-145 grown virus. Upon internalization, disassembly of the virus particles was observed. The two cell lines could be infected with PRRSV strains LV and VR-2332. However, it was observed that Marc-145 grown virus infected the cells more efficiently than macrophage grown virus. If the cells were treated with neuraminidase to remove cis-acting sialic acids that hinder the interaction of the virus with Sn, the amount of infected cells with macrophage grown virus increased. Comparison of both cell lines showed that the PK15Sn-CD163 cell line gave in general better results than the CHOSn-CD163 cell line. Only 2 out of 5 PRRSV strains replicated well in CHOSn-CD163 cells. Furthermore, the virus titer of all 5 PRRSV strains produced after passaging in PK15Sn-CD163 cells was similar to the virus titer of those strains produced in Marc-145 cells.

    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 (<300 μg/mL) dose-dependently inhibited LPS-induced NO production. Among them, the chloroform extract from G. lucidum was the most effective inhibitor, with the lowest half maximal inhibitory concentration (64.09 ± 6.29 μg/mL) of the LPS-induced NO production. These results indicate that extracts from medicinal 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 soluble protein nitrogen content and in vitro protein digestibility increased significantly (psquids significantly increased by all HHP treatments. (1)H nuclear magnetic resonance (NMR) showed that the main spectral changes associated to the anti-inflammatory properties of proteins following HHP treatment were in the range of 3.00-3.19 and 3.60-3.79ppm. This indicates that the HHP treatments modified the protein and functional properties of squids and gave the relevant chemical shifts in NMR signals, either migrated or disappeared. PMID:26948613

A range of four different homoisoflavanones (compounds 4a-4d) were synthesised from the corresponding substituted phenols. ¹H- and ¹³C-NMR data together with high-resolution mass spectroscopy data were employed to elucidate the structures. Anti-inflammatory activity was determined in mice with acute croton oil-induced auricular dermatitis. In vitro cytotoxicity was tested against a Chinese hamster ovarian cell line using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazoliumbromide (MTT) assay. Compound 4a exhibited a tendency to inhibit oedema in a dose-dependent manner after 3 and 6 h of treatment. Compounds 4b-4d also inhibited oedema, although a clear dose-response relationship was not observed. Compounds 4a-4c were found to be less cytotoxic than compound 4d. Compound 4b was the least cytotoxic. Compounds 4a-4d exhibited anti-inflammatory activity and varying levels of cytotoxicity. PMID:21950651

    This review focuses on the major, 'successful' target families in inflammation and attempts to identify some of the key features of what makes a good anti-inflammatory target. The review is based on a systematic analysis of approved anti-inflammatory drugs grouped according to their drug-target family. The cytokine family is a drug-dense area. They have yielded and continue to yield a rich stream of drugs. As in other therapeutic areas, G-protein-coupled receptors (GPCRs), also known as seven-transmembrane pass receptors, have provided significant drug targets. In addition, the superfamilies of cell adhesion molecules and co-stimulatory molecules, which have special relevance to immune processes, have begun to provide the first approved drugs and might yield many more. The recent, rapid increase in the number of defined targets in the immune system -- leukocyte surface antigens, cytokines, GPCRs, adhesion molecules and co-stimulatory molecules -- will ensure a rich stream of future anti-inflammatory drug targets.

    Full Text Available BACKGROUND: Disruption of the lymphatic vasculature causes edema, inflammation, and end-tissue destruction. To assess the therapeutic efficacy of systemic anti-inflammatory therapy in this disease, we examined the impact of a nonsteroidal anti-inflammatory drug (NSAID, ketoprofen, and of a soluble TNF-alpha receptor (sTNF-R1 upon tumor necrosis factor (TNF-alpha activity in a mouse model of acquired lymphedema. METHODS AND FINDINGS: Lymphedema was induced by microsurgical ablation of major lymphatic conduits in the murine tail. Untreated control mice with lymphedema developed significant edema and extensive histopathological inflammation compared to sham surgical controls. Short-term ketoprofen treatment reduced tail edema and normalized the histopathology while paradoxically increasing TNF-alpha gene expression and cytokine levels. Conversely, sTNF-R1 treatment increased tail volume, exacerbated the histopathology, and decreased TNF-alpha gene expression. Expression of vascular endothelial growth factor-C (VEGF-C, which stimulates lymphangiogenesis, closely correlated with TNF-alpha expression. CONCLUSIONS: Ketoprofen therapy reduces experimental post-surgical lymphedema, yet direct TNF-alpha inhibition does not. Reducing inflammation while preserving TNF-alpha activity appears to optimize the repair response. It is possible that the observed favorable responses, at least in part, are mediated through enhanced VEGF-C signaling.

In folk medicine, as various parts of this plant exhibit medicinal properties, it is used in the treatment of different ailments.The present study was designed to evaluate the potential anti-inflammatory and antinociceptive effects of methanolic extract of R. arboreum bark, followed by activity-guided fractionation of n-hexane, n-butanol, chloroform, ethyl acetate and aqueous fractions.The ethyl acetate fraction (200 mg/kg i.p.) showed the maximum analgesic effect (82%) in acetic acid-induced writhing, followed, to a less extent, by crude extract and chloroform fraction both at a dose of 200 mg/kg i.p. (65.09% and 67.89%, respectively). In carrageenan-induced mouse paw oedema, the crude extract and its related fractions displayed in a dose-dependent manner (50-200 mg/kg i.p.) an anti-inflammatory activity for all time-courses (1-5 hrs). For the active extract/fractions (200 mg/kg i.p.), the maximum effect was observed 5 h after carrageenan injection. These evidences were also supported by in vitro lipoxygenase inhibitory properties. In conclusion, R. arboreum crude methanolic extract and its fractions exhibited anti-inflammatory and antinociceptive effects. For these reasons, this plant could be a promising source of new compounds for the management of pain and inflammatory diseases. PMID:25501256

    The use of topical nonsteroidal anti-inflammatory drugs is widespread (particularly in countries bordering the Mediterranean). Compared to their wide use, the incidence of published adverse cutaneous effects appears minimal, although they are increasing. Most of them are a form of allergic contact dermatitis (ACD). Multiple sensitization and/or cross-reactions are rarely reported. Interestingly, our patient presented ACD with diclofenac and etofenamate (both from different chemical groups) and, furthermore, patch tests were positive with bencydamine and indomethacin (both indolacetic acid derivatives), piroxicam and fepradinol. We think that our results could not be explained due to cross-reactivity, and that multiple sensitization was more likely. PMID:8864624

    Full Text Available Abstract Background Epithelial ovarian cancer is one of the leading causes of gynaecological cancer morbidity and mortality in women. Early stage ovarian cancer is usually asymptomatic, therefore, is often first diagnosed when it is widely disseminated. Currently available diagnostics lack the requisite sensitivity and specificity to be implemented as community-based screening tests. The identification of additional biomarkers may improve the diagnostic efficiency of multivariate index assays. The aims of this study were to characterise and compare the ovarian tissue immunohistochemical localisation and plasma concentrations of three putative ovarian cancer biomarkers: human cationic antimicrobial protein-18 (hCAP-18; lactoferrin; and CD163 in normal healthy women and women with ovarian cancer. Methods In this case–control cohort study, ovarian tissue and blood samples were obtained from 164 women (73 controls, including 28 women with benign pelvic masses; 91 cancer, including 21 women with borderline tumours. Localisation of each antigen within the ovary was assessed by immunohistochemistry and serum concentrations determined by ELISA assays. Results Immunoreactive (ir hCAP-18 and lactoferrin were identified in epithelial cells, while CD163 was predominately localised in stromal cells. Tissue ir CD163 increased significantly (PP Conclusions The data obtained in this study establishes the localisation and concentrations of CD163, hCAP-18, and lactoferrin in ovarian tumours and peripheral blood. Individually, the 3 biomarkers display only modest diagnostic efficiency as assessed by AUC. When combined in a multivariate index assay, however, diagnostic efficiency increases significantly. As such, the utility of the biomarker panel, as an aid in the diagnosis of cancer in symptomatic women, is worthy of further investigation in a larger phase 2 biomarker trial.

    1987-01-01

    In order to ascertain the mode of anti-inflammatory action of a topical non-steroidal anti-inflammatory drug, etofenamate which is a diethylene glycol ester of flufenamic acid, the in vitro test for the mechanism of the action were carried out. Etofenamate (3 microM) was hydrolysed to flufenamic acid at a rate of 39.5% and 57.0% of the dose during 30 and 60 min incubation, respectively, when incubated with rat peritoneal macrophages stimulated with starch and bacto peptone in phosphate-buffered saline. PGE2 generation by these cells in MEM medium was dose-relatedly inhibited with etofenamate as well as flufenamic acid at the dosage range of 1 to 30 microM. This suggests that unchanged etofenamate is active, since the highest conversion rate of etofenamate to flufenamic acid was 15% of the dose during the incubation. Etofenamate produced a dose-related inhibition against lipoxygenase prepared from peritoneal polymorphonuclear leucocytes of guinea pigs, and its activity (IC50 = 5.3 X 10(-5) M) was stronger than that of caffeic acid; flufenamic acid was inactive. Inhibitory activity of etofenamate was one-third or less that of flufenamic acid against the hypotonic-hyperthermic lysis of rat erythrocytes and heat-denaturation of bovine serum albumin. From these results, it was suggested that topically applied etofenamate produces its anti-inflammatory action through prostaglandin synthesis inhibition by flufenamic acid produced in the inflammatory tissue and inhibition of prostaglandin synthesis by macrophages and lipoxygenase inhibition by unchanged etofenamate.

    Nitroglycerin (NTG) markedly enhances nitric oxide (NO) bioavailability. However, its ability to mimic the anti-inflammatory properties of NO remains unknown. Here, we examined whether NTG can suppress endothelial cell (EC) activation during inflammation and developed NTG nanoformulation to simultaneously amplify its anti-inflammatory effects and ameliorate adverse effects associated with high-dose NTG administration. Our findings reveal that NTG significantly inhibits human U937 cell adhesion to NO-deficient human microvascular ECs in vitro through an increase in endothelial NO and decrease in endothelial ICAM-1 clustering, as determined by NO analyzer, microfluorimetry, and immunofluorescence staining. Nanoliposomal NTG (NTG-NL) was formulated by encapsulating NTG within unilamellar lipid vesicles (DPhPC, POPC, Cholesterol, DHPE-Texas Red at molar ratio of 6:2:2:0.2) that were ~155 nm in diameter and readily uptaken by ECs, as determined by dynamic light scattering and quantitative fluorescence microscopy, respectively. More importantly, NTG-NL produced a 70-fold increase in NTG therapeutic efficacy when compared with free NTG while preventing excessive mitochondrial superoxide production associated with high NTG doses. Thus, these findings, which are the first to reveal the superior therapeutic effects of an NTG nanoformulation, provide the rationale for their detailed investigation for potentially superior vascular normalization therapies.

    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. PMID:26272937

    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. PMID:26853111

    Full Text Available It has become clear that the inflammatory immune system is altered during the course of clinical depression. In particular, the human data have found depression to be associated with disturbances in the trafficking of cells of the adaptive immune system, coupled with elevations of innate immune messengers and pro-inflammatory cytokines. Paralleling these findings, stressor-based animal models of depression have implicated several cytokines, most notably interelukin-1β (IL-1β, IL-6 and tumor necrosis factor-α (TNF-α. Elevations of these cytokines and general inflammatory indicators, such as C-reactive protein, together with reductions of specific immune cells (e.g. T lymphocytes might serve as useful biomarkers of depression or at least, certain subtypes of the disorder. Recent reports also suggest the possibility that anti-inflammatory agents could have therapeutic value in acting as adjunct treatments with traditional antidepressants. Along these lines, we presently discuss the evidence for pro-inflammatory cytokine involvement in depression, as well as the possibility that anti-inflammatory agents and trophic cytokines themselves might have important anti-depressant properties.

    Solanum corymbiflorum is popularly known as "baga-de-veado" and its leaves are applied on inflamed legs, scabies, tick bite, boils, mastitis, low back pain and otitis. The aim of this study was evaluate anti-inflammatory in vivo activity and relate this activity with antioxidant compounds present in the extract of S. corymbiflorum leaves. The extract from S. corymbiflorum leaves topically applied was able to reduce the croton oil-induced ear edema and myeloperoxidase (MPO) activity with maximum inhibition of 87±3% and 45±7%, rescpectively in the dose of 1mg/ear. Similar results were found for positive control dexamethasone, which presented inhibitions of ear edema and MPO activity of 89±3% and 50±3%, respectively in a dose of 0.1mg/ear. These findings are due, at least in part, the presence of polyphenols (195.28mg GAE/g) and flavonoids, as chlorogenic acid (59.27mg/g), rutin (12.72mg/g), rosmarinic acid, caffeic acid and gallic acid found by high performance liquid chromatography (HPLC) analysis. This species showed potencial antioxidant by 1,1-diphenyl-2-picrylhydrazyl (DPPH), and carbonyl groups in proteins methods which may be related with the presence of this compounds. This species possess anti-inflammatory activity confirming their popular use for the local treatment of skin inflammatory disorders. PMID:26721215

    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.

    Full Text Available Camellia japonica oil (CJ oil has been used traditionally in EastAsia to nourish and soothe the skin as well as help restore theelasticity of skin. CJ oil has also been used on all types ofbleeding instances. However, little is known about itsanti-inflammatory effects. Therefore, the anti-inflammatoryeffects of CJ oil and its mechanisms of action were investigated.CJ oil inhibited LPS-induced production of NO, PGE2, andTNF-α in RAW264.7 cells. In addition, expression of COX-2and iNOS genes was reduced. To evaluate the mechanism ofthe anti-inflammatory activity of CJ oil, LPS-induced activationof AP-1 and NF-κB promoters was found to be significantlyreduced by CJ oil. LPS-induced phosphorylation of IκBα, ERK,p38, and JNK was also attenuated. Our results indicate that CJoil exerts anti-inflammatory effects by downregulating theexpression of iNOS and COX-2 genes through inhibition ofNF-κB and AP-1 signaling.

  13. Develop Anti-Inflammatory Nanotherapies to Treat Cardiovascular Disease

    Science.gov (United States)

    Tang, Jun

    Cardiovascular disease (CVD) is the leading cause of disease-related death in the world, accounting for 30 % global mortality. The majority of CVD is caused by atherosclerosis, a chronic inflammatory disease of major arteries featured by the deposition of lipids and cholesterol. Inflammation of atherosclerosis is mainly promoted by the pathological macrophages and monocytes, and modulating their functions has been proposed as a promising therapeutic target. This dissertation first presents the development of a novel simvastatin-loaded high-density lipoprotein (HDL) based nanoparticle ([S]-rHDL), which was able to deliver anti-inflammatory simvastatin preferentially to inflammatory monocytes in the blood and to macrophages in advanced atherosclerotic plaques, leading to the reduced inflammation in the tissue. Second, extensive in vivo characterization of [S]-rHDL in a mouse atherosclerosis model revealed that the anti-inflammatory capability of [S]-rHDL derived from its effects on blood monocytes, endothelial layer, monocyte recruitment, and plaque macrophage function. Third, a translational study that integrated the use of [S]-rHDL into oral statin treatment demonstrated a great potential for this nanomedicine as an attractive addition to the current high-dose oral statin standard-of-care for acute coronary syndrome. Finally, preliminary results suggested potential applications of the rHDL platform to other macrophage-implicated diseases.

    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.

  16. 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.

  4. Anti-inflammatory and antifibrotic effects of methyl palmitate

    International Nuclear Information System (INIS)

    Methyl palmitate (MP) has been shown earlier to inhibit Kupffer cells and rat peritoneal macrophages. To evaluate the potential of MP to inhibit the activation of other macrophages, RAW cells (macrophages of alveolar origin) were treated with varying concentrations of MP (0.25, 0.5, 1 mM). Assessment of cytotoxicity using MTT assay revealed that 0.25 and 0.5 mM are not toxic to RAW cells. MP was able to inhibit the phagocytic function of RAW cells. Treatment of cells with MP 24 hours prior to LPS stimulation significantly decreased nitric oxide release and altered the pattern of cytokines release; there was a significant decrease in TNF-α and a significant increase in IL-10 compared to the controls. However, there is a non-significant change in IL-6 level. Furthermore, phosphorylation of inhibitory kappa B (IκBα) protein was significantly decreased in RAW cells treated with 0.5 mM MP after LPS stimulation. Based upon the in-vitro results, it was examined whether MP treatment will be effective in preventing bleomycin-induced lung inflammation and fibrosis in-vivo. Bleomycin given by itself caused destruction of the lung architecture characterized by pulmonary fibrosis with collapse of air alveoli and emphysematous. Bleomycin induced a significant increase in hydroxyproline level and activated NF-κB, p65 expression in the lung. MP co-treatment significantly ameliorated bleomycin effects. These results suggest that MP has a potential of inhibiting macrophages in general. The present study demonstrated for the first time that MP has anti-inflammatory and antifibrotic effect that could be through NF-kB inhibition. Thus MP like molecule could be a promising anti-inflammatory and antifibrotic drug. - Research highlights: →Methyl palmitate is a universal macrophage inhibitor. →It could be a promising nucleus of anti-inflammatory and antifibrotic drugs. →The underlying mechanism of these effects could be through NF-kB inhibition.

  5. Anti-inflammatory effects of hydroxycinnamic acid derivatives

    International Nuclear Information System (INIS)

    NF-κB family of transcription factors are involved in numerous cellular processes, including differentiation, proliferation, and inflammation. It was reported that hydroxycinnamic acid derivatives (HADs) are inhibitors of NF-κB activation. Rice bran oil contains a lot of phytosteryl ferulates, one of HADs. We have investigated effects of phytosteryl ferulates on NF-κB activation in macrophage. Cycloartenyl ferulate (CAF), one of phytosteryl ferulates, significantly reduced lipopolysaccharide (LPS)-induced NO production and mRNA expression of inducible NO synthase and cyclooxygenese-2 but upregulated SOD activity. Electrophoresis mobility shift assay revealed that CAF inhibited DNA-binding of NF-κB. CAF and phytosteryl ferulates probably have potentially anti-inflammatory properties

    2014-06-01

    Full Text Available Macrolides are a group of antibiotics whose activity is ascribable to the presence of the macrolide ring, to which one or more deoxy sugars may be attached. Two properties are inherent in this group of antibiotics, the immunomodulatory and the anti-inflammatory actions, ensuring great efficacy in a wide spectrum of infections. Macrolides demonstrate several immunomodulatory activities both in vitro and in vivo. They can down-regulate prolonged inflammation, increase mucus clearance, prevent the formation of bacterial biofilm and either enhance or reduce activation of the immune system. According to given properties and exceptional effects on bacterial phatogens, the macrolide antimicrobial agents have been found to serve a unique role in the management of chronic airway disorders, including diffuse panbronchiolitis, cystic fibrosis and chronic obstructive pulmonary disease. Use of macrolides can result in clinical improvement in patients with severe, chronic inflammatory airway diseases, improving their spirometry indicators, gas exchange and overall quality of life.

    Oxidized phospholipids are generally recognized as deleterious factors involved in disease pathogenesis. This review summarizes the data suggesting that under certain biological conditions the opposite is correct, namely that OxPLs can also induce protective effects. Examples that are discussed in the review include upregulation of antioxidant genes, inhibition of inflammatory signaling pathways through Nrf2-dependent and -independent mechanisms, antagonism of Toll-like receptors, immuno-modulating and immuno-suppressive action of OxPLs in adaptive immunity and autoimmune disease, activation of PPARs known for their anti-inflammatory action, as well as protective action against lung edema in acute lung inflammation. The data support the notion that oxidation of phospholipids provides a negative feedback preventing damage to host tissues due to uncontrolled inflammation and oxidative stress. PMID:26948981

    The identification of substances that can promote the resolution of inflammation in a way that is homeostatic, modulatory, efficient, and well-tolerated by the body is of fundamental importance. Traditional medicines have long provided front-line pharmacotherapy for many millions of people worldwide. Medicinal extracts are a rich source of therapeutic leads for the pharmaceutical industry. The use of medicinal plant therapies to treat chronic illness, including rheumatoid arthritis (RA) and inflammatory bowel disease (IBD), is thus widespread and on the rise.The aim of this review is to present recent progress in clinical anti-inflammatory studies of plant extracts and compound leads such as green tea polyphenols, curcumin, resveratrol, boswellic acid, and cucurbitacins, among others, against chronic inflammatory diseases, mainly RA and IBD. In this context, the present paper also highlights the most promising experimental data on those plant extracts and pure compounds active in animal models of the aforementioned diseases.

The increased vascular permeability elicited by intradermal injection of histamine, 5-HT, bradykinin, PGE1, carrageenin and compound 48/80 was also suppressed. The anti-inflammatory effect was not significantly altered by propranolol and adrenalectomy on the thermal and carrageenin edema, it was variably inhibited on the skin test, and was completely abolished on the paw swelling induced by 5-HT and compound 48/80. Since insulin had little or no effect on the vascular response when given topically together with the vasoactive agents, its complex effect on the acute inflammation appears to be brought about via indirect mechanisms.

    Objective To explore the anti-inflammatory effects of magnoliae fargesii volatile oil.Methods Human umbilical vein endothelial cells (HUVECs) were stimulated by TNF-α to express the adhesion molecules. Then the anti-adhesion effects of magnoliae fargesii volatile oil between HUVECs and human peripheral neutrophils were observed. The ischemia-reperfusion animal models were established by 60min renal ischemia followed by 1, 3, 6 and 24h reperfusion. Rats were randomly divided into the following groups: the sham-operation controls, ischemic group only treated with normal saline, and treated group infused magnoliae fargesii volatile oil before reperfusion. Then the renal injury of rats was detected. Results High rate of cell adhesion between HUVECs and neutrophils was observed. Magnoliae fargesii volatile oil could inhibit the adhesion process at the concentration of 0.5μL/mL (191.6±8.6), 1.0μL/mL (158.2±9.0) and 2.0μL/mL (155.2±9.7) (P<0.05). The anti-adhesion effects were strengthened with the increase of volatile oil concentration. Blood urea nitrogen and creatinine levels of the animal models were significantly increased after 24h reperfusion while the increase was remarkably attenuated by the treatment with magnoliae fargesii volatile oil. The renal injury was severe after 1h reperfusion, which was significantly attenuated by the treatment of magnoliae fargesii volatile oil. Conclusion Magnoliae fargesii volatile oil has anti-inflammatory effects.

    Full Text Available Abstract Background Antidepressants are heavily prescribed drugs and have been shown to affect inflammatory signals. We examined whether these have anti-inflammatory properties in animal models of septic shock and allergic asthma. We also analysed whether antidepressants act directly on peripheral cell types that participate in the inflammatory response in these diseases. Methods The antidepressants desipramine and fluoxetine were compared in vivo to the glucocorticoid prednisolone, an anti-inflammatory drug of reference. In a murine model of lipopolysaccharides (LPS-induced septic shock, animals received the drugs either before or after injection of LPS. Circulating levels of tumour necrosis factor (TNF-α and mortality rate were measured. In ovalbumin-sensitized rats, the effect of drug treatment on lung inflammation was assessed by counting leukocytes in bronchoalveolar lavages. Bronchial hyperreactivity was measured using barometric plethysmography. In vitro production of TNF-α and Regulated upon Activation, Normal T cell Expressed and presumably Secreted (RANTES from activated monocytes and lung epithelial cells, respectively, was analysed by immunoassays. Reporter gene assays were used to measure the effect of antidepressants on the activity of nuclear factor-κB and activator protein-1 which are involved in the control of TNF-α and RANTES expression. Results In the septic shock model, all three drugs given preventively markedly decreased circulating levels of TNF-α and mortality (50% mortality in fluoxetine treated group, 30% in desipramine and prednisolone treated groups versus 90% in controls. In the curative trial, antidepressants had no statistically significant effect, while prednisolone still decreased mortality (60% mortality versus 95% in controls. In ovalbumin-sensitized rats, the three drugs decreased lung inflammation, albeit to different degrees. Prednisolone and fluoxetine reduced the number of macrophages, lymphocytes

    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.

    2010-11-01

    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. PMID:21084786

    Twelve hydrolyzable tannins were obtained from the twigs of Myricaria bracteata, including two new hellinoyl-type dimers, bracteatinins D1 (1) and D2 (2); a new hellinoyl-type trimer, bracteatinin T1 (3); two known monomers, nilotinin M4 (4) and 1,3-di-O-galloyl-4,6-O-(aS)-hexahydroxydiphenoyl-β-d-glucose (5); six known dimers, tamarixinin A (6), nilotinin D8 (7), hirtellins A (10), B (9), and E (8), and isohirtellin C (11); and a known trimer, hirtellin T3 (12). The structures of the tannins were elucidated by spectroscopic data analysis and comparisons to known tannins. All compounds were evaluated as free radical scavengers using 1,1-diphenyl-2-picrylhydrazyl and hydroxy radicals and compared to the activity of BHT and Trolox. Compound 6 showed a significant anti-inflammatory effect on croton oil-induced ear edema in mice (200 mg/kg, inhibition rate 69.8%) and on collagen-induced arthritis in DBA/1 mice (20 mg/kg, inhibition rate 46.0% at day 57).

    Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used for treatment of orthopedic diseases, inflammatory diseases, etc., and low-dose aspirin is a common antiplatelet therapy given mainly for secondary prevention of atherothrombosis (e.g., myocardial infarction and cerebral infarction). As to the history of NSAID-induced gastric mucosal injury in Japan, the first case of an aspirin-induced gastric ulcer was reported as early as 1934. Based on a meta-analysis of risk factors for peptic ulcers, Helicobacter pylori infection and NSAIDs are the main etiologies of peptic ulcers. NSAIDs alone increase the odds ratio for ulcer development to 19.4 and that for ulcer bleeding to 4.85. In fact, the Japan Rheumatism Foundation reported in 1991 that active gastric ulcers and active duodenal ulcers were detected in 15.5 and 1.9 % of 1008 patients, respectively, taking oral NSAIDs for 3 months or longer. In Japan, which is becoming an increasingly aged society, the numbers of patients taking NSAIDs and low-dose aspirin are expected to increase dramatically in the future. It is hoped that accumulation of evidence on gastrointestinal risk will allow many patients to rationally avoid gastrointestinal complications while receiving the benefits of NSAIDs and low-dose aspirin.

  6. Nonsteroidal Anti-Inflammatory Drug Hypersensitivity in Preschool Children

    Full Text Available Although extensively studied in adults, nonsteroidal anti-inflammatory drug (NSAID hypersensitivity in children, especially in young children, remains poorly defined. Pediatricians, prescribing antipyretics for children, rarely encounter significant problems, but the few epidemiologic studies performed show conflicting results. Although it is clear that some patients with acetylsalicylic acid (ASA-sensitive asthma have their clinical onset of disease in childhood and bronchoconstriction after ASA challenge is seen in 0 to 22% of asthmatic children so challenged, ibuprofen at antipyretic doses may cause acute respiratory problems only in a very small number of mild to moderate asthmatics. The recently elucidated mechanism of action of acetaminophen may explain some occurrences of adverse reactions in patients with cross-reactive NSAID hypersensitivity on the basis of its inhibitory activity on the newly described enzyme, cyclooxygenase (COX-3. This nonspecific sensitivity to inhibition of COX is most likely genetically determined and shows a remarkable association with atopic disease even in the very young age group and possibly an increased predilection in specific ethnic groups. This review summarizes state-of-the-art published data on NSAID hypersensitivity in preschool children.

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

    Directory of Open Access Journals (Sweden)

    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.

    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.

    Porcine reproductive and respiratory syndrome (PRRS) is the most economically important disease to the swine industry, and effective prevention strategy for this disease is still required. Guanylate-binding protein 1 (GBP1) and myxovirus resistance protein 1 (Mx1) are two important proteins belonging to the GTPase superfamily that have been previously described to show antiviral effects. CD163 is considered the most important receptor for PRRSV attachment and internalization. Therefore, the aim of the present study was to evaluate the effects of these genes on host resistance against PRRSV infection in conjunction with the host immune response following PRRSV challenge. The results showed that pigs with AG genotype for the GBP1 exon2 exhibited a significantly higher average daily weight gain (ADWG) and lower average viremia than AA or GG genotype. Furthermore, pigs harbouring the AG genotype for the GBP1 gene presented greater CD4(+)CD25(+) and CD8(+)CD25(+) T cell populations at 4 and 18 days post challenge (dpc), respectively, as compared with other genotypes whereas pigs with CC genotype for the CD163 gene displayed significantly higher nucleocapsid-specific antibody titers at 11dpc. However, pigs with a single 11-bp deletion or insertion in the Mx1 gene did not show significant differences in either weight gain or viremia. Based on these results, we concluded that GBP1 is most significantly associated with resistance against PRRSV infection and efficient T cell activation in pigs. PMID:26711047

    Highlights: • We examined epoxygenase product formation and regulation in endothelial cells. • The epoxygenase CYP2J2 is an LPS (TLR-4) inducible enzyme in endothelial cells. • The endothelial cell line EA.Hy926 synthesises epoxygenase products. • Inhibition of endothelial epoxygenases increases TNFα secretion. • Soluble epoxide hydrolase inhibitors reduce inflammation-induced TNFα and NFκB. - Abstract: The roles of CYP lipid-metabolizing pathways in endothelial cells are poorly understood. Human endothelial cells expressed CYP2J2 and soluble epoxide hydrolase (sEH) mRNA and protein. The TLR-4 agonist LPS (1 μg/ml; 24 h) induced CYP2J2 but not sEH mRNA and protein. LC–MS/MS analysis of the stable commonly used human endothelial cell line EA.Hy926 showed active epoxygenase and epoxide hydrolase activity: with arachidonic acid (stable epoxide products 5,6-DHET, and 14,15-DHET), linoleic acid (9,10-EPOME and 12,13-EPOME and their stable epoxide hydrolase products 9,10-DHOME and 12,13-DHOME), docosahexaenoic acid (stable epoxide hydrolase product 19,20-DiHDPA) and eicosapentaenoic acid (stable epoxide hydrolase product 17,18-DHET) being formed. Inhibition of epoxygenases using either SKF525A or MS-PPOH induced TNFα release, but did not affect LPS, IL-1β, or phorbol-12-myristate-13-acetate (PMA)-induced TNFα release. In contrast, inhibition of soluble epoxide hydrolase by AUDA or TPPU inhibited basal, LPS, IL-1β and PMA induced TNFα release, and LPS-induced NFκB p65 nuclear translocation. In conclusion, human endothelial cells contain a TLR-4 regulated epoxygenase CYP2J2 and metabolize linoleic acid > eicosapentaenoic acid > arachidonic acid > docosahexaenoic acid to products with anti-inflammatory activity.

    2012-01-01

    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.

    A bioassay-guided fractionation and chemical investigation of the MeOH extract of Raphanus sativus seeds resulted in the isolation and identification of eight phenylpropanoid sucrosides (1-8) including two new compounds, named raphasativuside A and B (1-2) from the most active CHCl₃-soluble fraction. The structures of these new compounds were elucidated through spectral analysis, including extensive 2D-NMR data, and chemical reaction experiments. We evaluated the anti-inflammatory effects of 1-8 in lipopolysaccharide (LPS)-stimulated murine microglia BV2 cells. Compounds 2 and 5 exhibited significant inhibitory effect on nitric oxide production in LPS-activated BV-2 cells with IC₅₀ values of 21.63 and 26.96 μM, respectively. All isolates were also evaluated for their antiproliferative activities against four human tumor cell lines (A549, SK-OV-3, SK-MEL-2, and HCT-15). Compounds 1-7 showed consistent cytotoxicity against A549, SK-OV-3, SK-MEL-2, and HCT-15 cell lines with IC50 values of 6.71-27.92 μM. Additionally, the free-radical scavenging activity of 1-8 was assessed using the DPPH (2,2-diphenyl-1-picrylhydrazyl) assay where compounds 1, 3, and 4 scavenged DPPH radical strongly with IC₅₀ values of 23.05, 27.10, and 29.63 μg/mL, respectively.

    2016-03-16

    A set of four water-soluble perylene bisimides (PBI) based on sulfated polyglycerol (PGS) dendrons were developed, their photophysical properties determined via UV/vis and fluorescence spectroscopy, and their performance as possible anti-inflammatory agents evaluated via biological in vitro studies. It could be shown that in contrast to charge neutral PG-PBIs the introduction of the additional electrostatic repulsion forces leads to a decrease in the dendron generation necessary for aggregation suppression, allowing the preparation of PBIs with fluorescence quantum yields of >95% with a considerable decreased synthetic effort. Furthermore, the values determined for L-selectin binding down to the nanomolar range, their limited impact on blood coagulation, and their minor activation of the complement system renders these systems ideal for anti-inflammatory purposes.

    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

    Wild bitter gourd (Momordica charantia L. var. abbreviate Seringe), a common vegetable in Asia, is used in traditional medicine to treat various diseases, including inflammation. Extant literature indicates that wild bitter gourds have components that activate PPARα and PPARγ. This research probed the influence of adding wild bitter gourd to diets on inflammation responses in mice with sepsis induced by intraperitoneal injection of LPS. Male BALB/c mice were divided normal, sepsis, positive control, and three experimental groups. The latter ate diets with low (1%), moderate (2%), and high (10%) ratios of wild bitter gourd lyophilized powder. Before mice were sacrificed, with the exception of the normal group, intraperitoneal injection of LPS induced sepsis in each group; positive control group was injected with LPS after PDTC. This experiment revealed starkly lower weights in groups with added wild bitter gourd than those of the remaining groups. Blood lipids (TG, cholesterol, and NEFA) were also lower in comparison to the sepsis group, and blood glucose concentrations recovered and approached normal levels. Blood biochemistry values related to inflammation reactions indicated GOT, GPT, C-RP, and NO concentrations of groups with added wild bitter gourd were all lower than those of the sepsis group. Secretion levels of the spleen pro-inflammatory cytokines IL-1, IL-6, and TNF-α tallied significantly lower in comparison to the sepsis group, whereas secretion levels of IL-10 anti-inflammatory cytokine increased. Expression level of proteins NF-κB, iNOS, and COX-2 were significantly inhibited. Results indicate wild bitter gourd in diets promoted lipid metabolism, reducing fat accumulation, and improving low blood glucose in sepsis. Addition of wild bitter gourd can reduce inflammation biochemical markers or indicators and pro-inflammatory cytokines in the body, hence improving the inflammation responses in mice with sepsis.

    The association between hyperglycemia and inflammation and vascular complications in diabetes is now well established. Antidiabetes drugs may alleviate inflammation by reducing hyperglycemia; however, the anti-inflammatory effects of these medications are inconsistent and it is unknown whether their beneficial metabolic effects are mediated via modulation of chronic inflammation. Recent data suggest that immunomodulatory treatments may have beneficial effects on glycemia, β-cell function, and insulin resistance. However, the mechanisms underlying their beneficial metabolic effects are not always clear, and there are concerns regarding the specificity, safety, and efficacy of immune-based therapies. Herein, we review the anti-inflammatory and metabolic effects of current antidiabetes drugs and of anti-inflammatory therapies that were studied in patients with type 2 diabetes. We discuss the potential benefit of using anti-inflammatory treatments in diabetes and important issues that should be addressed prior to implementation of such therapeutic approaches. PMID:27440839

    Anti-inflammatory and analgesic activities of topically applied etofenamate gel (5% etofenamate) were investigated in experimental animals. Etofenamate gel showed a dose related inhibition against vascular permeability caused by histamine in mice and ultra violet light-induced erythema in guinea pigs at doses of 10--100 mg/site and 25--200 (ED50 = 26.6) mg/site, respectively. The erythema was not inhibited with its topical application of 100 mg/site to the skin distant from the erythema. Granuloma formation, caused by felt-pellet implantation, was inhibited in a dose dependent manner by repeated application of etofenamate gel (10--100 mg/site/day). Etofenamate gel inhibited the pain-like responses in both the arthritic joint and the edematous hind paw of rats with 50--200 mg/joint and 100 mg/paw, respectively. In these tests, the vehicle gel did not show any significant activity. The potency of etofenamate gel was stronger than that of adrenal-extracts ointment (Mobilat) and approximately comparable to indomethacin ointment (1% indomethacin) in a weight basis of formulations. Topical application of etofenamate (0.5--2 mg/ear) resulted in a dose related decrease of contact hypersensitivity to oxazolone in mice, and its activity was nearly equipotent to flufenamic acid and about one-fourth that of indomethacin. From these results, it was suggested that etofenamate gel, applied topically to the inflamed tissue, showed a certain inhibitory activity against acute and subacute-chronic inflammation and inflammatory pain-like responses.

    Full Text Available BACKGROUND: We have previously investigated the microlocalisation of M1 and M2 macrophages in NSCLC. This study investigated the non-macrophage (NM expression of proteins associated with M1 and M2 macrophages in NSCLC. METHODS: Using immunohistochemistry, CD68(+ macrophages and proteins associated with either a cytotoxic M1 phenotype (HLA-DR, iNOS, and MRP 8/14, or a non-cytotoxic M2 phenotype (CD163 and VEGF were identified. NM expression of the markers was analysed in the islets and stroma of surgically resected tumours from 20 patients with extended survival (ES (median 92.7 months and 20 patients with poor survival (PS (median 7.7 months. RESULTS: The NM expression of NM-HLA-DR (p<0.001, NM-iNOS (p = 0.02 and NM-MRP 8/14 (p = 0.02 was increased in ES compared to PS patients in the tumour islets. The tumour islet expression of NM-VEGF, was decreased in ES compared to PS patients (p<0.001. There was more NM-CD163 expression (p = 0.04 but less NM-iNOS (p = 0.002 and MRP 8/14 (p = 0.01 expression in the stroma of ES patients compared with PS patients. The 5-year survival for patients with above and below median NM expression of the markers in the islets was 74.9% versus 4.7% (NM-HLA-DR p<0.001, 65.0% versus 14.6% (NM-iNOS p = 0.003, and 54.3% versus 22.2% (NM-MRP 8/14 p = 0.04, as opposed to 34.1% versus 44.4% (NM-CD163 p = 0.41 and 19.4% versus 59.0% (NM-VEGF p = 0.001. CONCLUSIONS: Cell proteins associated with M1 and M2 macrophages are also expressed by other cell types in the tumour islets and stroma of patients with NSCLC. Their tissue and cellular microlocalisation is associated with important differences in clinical outcome.

    Full Text Available Caesalpinia bonduc possess anti-inflammatory, anthelmintic, digestive, stomachic properties. The present study investigated anti-inflammatory and in vitro anticancer studies of stem bark of C.bonduc. The in vitro antiinflammatory study of different extracts were done by Protein denaturation method. The total ethanolic extract of stem bark of C.bonduc was investigated for in vivo anti-inflammatory activity (carrageenan induced rat paw oedema at the doses 200 and 400mg/kg body weight in male Wister albino rats. The in vitro cytotoxicity study was done by Trypan blue dye exclusion technique in Daltons Ascites Lymphoma (DLA cells at 200, 100, 50, 20, 10 μg/ml concentrations. Estimation studies by Folin Cio-calteau method and Aluminium chloride colorimetric method showed that phenolics and flavonoids are abundant in the stem bark. The in vitro and in vivo anti-inflammatory studies shows that TEE exhibits more anti-inflammatory effect which increases in a dose dependent manner. TEE exhibits 100% cytotoxicity even at 100 μg/ml concentrations. The present study revealed that presence high quantities of phenolics and flavonoids in the stem bark may be responsible for its anti-inflammatory anticancer properties.

    This study was carried out to evaluate the anti-inflammatory and free radical scavenging activities of flavans from flex centrochinensis S. Y. Hu in vitro and their structure-activity relationship. LPS-stimulated RAW 264.7 macrophage was used as inflammatory model. MTT assay for cell availability, Griess reaction for nitric oxide (NO) production, the content of TNF-alpha, IL-1beta, IL-6 and PGE, were detected with ELISA kits; DPPH, superoxide anion and hydroxyl free radicals scavenging activities were also investigated. According to the result, all flavans tested exhibited anti-inflammatory effect in different levels. Among them, compounds 1, 3, 4 and 6 showed potent anti-inflammatory effect through the inhibition of NO, TNF-alpha, IL-lp and IL-6, of which 1 was the most effective inhibitor, however, 2 and 5 were relatively weak or inactive. The order of free radical scavenging activities was similar to that of anti-inflammatory activities. Therefore, these results suggest that 3, 4 and 6, especially of 1, were,in part responsible for the anti-inflammatory and free radical scavenging activity of Ilex centrochinensis. Hydroxyl group at 4'-position of B-ring plays an important role in the anti-inflammatory and free radical scavenging capacities. PMID:26281592

    Full Text Available 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.

    In present study, the anti-inflammatory potential of three medicinal plants, Xanthium strumarium, Achyranthes aspera and Duchesnea indica were evaluated, using both in vitro and in vivo assays. Carrageenan induced hind paw edema model was used to carry out the in vivo anti-inflammatory activity, while for in vitro screening lipoxygenase inhibition assay was used. Crude extract of all the selected plants depicted significant (plt;0.001) anti-inflammatory activity, at late phase of inflammation. Achyranthes aspera also showed considerable anti-inflammatory activity (47%) at relatively lower concentration (200 mg/ml), at the initial phase of inflammation. Similarly the ethyl acetate fraction of all the selected plants showed significant lipoxygenase inhibition activity when compared with the standard drug (Baicalein). The results obtained from both in vitro and in vivo anti-inflammatory activity suggest that the ethyl acetate fraction of the crude extract of all the selected plants can be used for the isolation of new lead compounds with better anti-inflammatory activity.

  10. Cardiovascular complications of non-steroidal anti-inflammatory drugs.

    Fosslien, Egil

    2005-01-01

    Coxibs, such as rofecoxib, celecoxib, and valdecoxib, selectively inhibit cyclooxygenase (COX)-2, the mainly inducible, pro-inflammatory COX isoform. Unlike traditional non-steroidal anti-inflammatory drugs (NSAIDs) most coxibs do not significantly inhibit COX-1 and are therefore less toxic to the gastrointestinal tract. Hence, coxibs widely replaced traditional NSAIDs for treatment of arthritis and other painful inflammatory conditions. In many, but not all, clinical studies, coxibs became associated with higher risks of myocardial infarction (MI) and stroke. Several mechanisms may be involved in the pathogenesis of such complications. First, selective inhibition of COX-1 lowers platelet synthesis of thromboxane (TXA(2)), a thrombogenic and atherogenic eicosanoid. Selective inhibition of COX-2 limits endothelial cell synthesis of prostacyclin (PGI(2)), an arachidonic acid product that opposes the effects of thromboxane. In apoE-/- mice, interruption of TXA(2) signaling by deletion of its receptor (TP) limits atherogenesis, whereas interruption of PGI2 signaling by deletion of its receptor (IP) accelerates atherogenesis. This suggests that selective inhibition of COX-2 can disrupt the physiological balance between thromboxane and prostacyclin and thus increase atherosclerosis, thrombogenesis, and the risk of cardiovascular complications. Second, COX inhibition can raise levels of arachidonic acid, which can inhibit mitochondrial oxidative phosphorylation (OXPHOS) and increase OXPHOS generation of reactive oxygen species. Several NSAIDs, including coxibs and meloxicam, directly uncouple or inhibit OXPHOS. Studies of apoE-/- mice indicate that mitochondrial dysfunction plays an early role in atherogenesis. Third, many NSAIDs exhibit COX-independent properties. For example, in animal models, short-term treatment with celecoxib reduces monocyte chemotaxis by reducing expression of monocyte chemoattractant protein (MCP)-1. However, long-term treatment results in the

    Objective: To study anti-inflammatory and analgesic activities in swiss albino mice, two schiff bases namely acetophenone semicarbazone (ASC) and benzophenone semicarbazone (BSC) were synthesized and characterized. Methods: Two doses of the test compounds 25 and 50 mg/kg (p.o) for each were selected throughout the research work. The anti-inflammatory activity of the test compounds was determined by ‘carragenan induced mice paw edema inhibition’ method. The analgesic activity was determined by both, ‘acetic acid induced writhing’ and ‘tail immersion' methods. All such data were compared with standard drugs at the dose of 10 mg/kg (p.o.). Results:Both ASC and BSC have showed positive effects as anti-inflammatory and analgesic agents. Anti-inflammatory and analgesic activities of the test compounds at 50 mg/kg (p.o.) were quite comparable to those of standard drugs at 10 mg/kg (p.o.). Conclusion: Both ASC and BSC can be considered as potent anti-inflammatory and analgesic agents.

The aim of this review is to report the pharmacological potential of plants of Clusiaceae family with the anti-inflammatory activity in animal experiments. Methods. A systematic review about experiments investigating anti-inflammatory activity of Clusiaceae family was carried out by searching bibliographic databases such as Medline, Scopus and Embase. In this update, the search terms were “anti-inflammatory agents,” “Clusiaceae,” and “animals, laboratory.” Results. A total of 255 publications with plants this family were identified. From the initial 255 studies, a total of 21 studies were selected for the final analysis. Studies with genera Allanblackia, Clusia, Garcinia or Rheedia, and Hypericum showed significant anti-inflammatory activity. The findings include a decrease of total leukocytes, a number of neutrophils, total protein concentration, granuloma formation, and paw or ear edema formation. Other interesting findings included decreased of the MPO activity, and inflammatory mediators such as NF-κB and iNOS expression, PGE2 and Il-1β levels and a decrease in chronic inflammation. Conclusion. The data reported suggests the anti-inflammatory effect potential of Clusiaceae family in animal experiments.

  13. Enhancement of Anti-Inflammatory Activity of Curcumin Using Phosphatidylserine-Containing Nanoparticles in Cultured Macrophages

    Directory of Open Access Journals (Sweden)

    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.

    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.

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.

    Full Text Available 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.

    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. PMID:27088973

    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.

    2016-02-01

    Novel amides of non steroidal anti-inflammatory drugs (NSAIDs), α-lipoic acid and indole-3-acetic acid with thiomorpholine were synthesised by a simple method and at high yields (60-92%). All the NSAID derivatives highly decreased lipidemic indices in the plasma of Triton treated hyperlipidemic rats. The most potent compound was the indomethacin derivative, which decreased total cholesterol, triglycerides and LDL cholesterol by 73%, 80% and 83%, respectively. They reduced acute inflammation equally or more than most parent acids. Hence, it could be concluded that amides of common NSAIDs with thiomorpholine acquire considerable hypolipidemic potency, while they preserve or augment their anti-inflammatory activity, thus addressing significant risk factors for atherogenesis.

    Accumulating evidence supports an association between depression and inflammatory processes, a connection that seems to be bidirectional. Clinical trials have indicated antidepressant treatment effects for anti-inflammatory agents, both as add-on treatment and as monotherapy. In particular......, nonsteroidal anti-inflammatory drugs (NSAIDs) and cytokine-inhibitors have shown antidepressant treatment effects compared to placebo, but also statins, poly-unsaturated fatty acids, pioglitazone, minocycline, modafinil, and corticosteroids may yield antidepressant treatment effects. However, the complexity of...... the inflammatory cascade, limited clinical evidence, and the risk for side effects stress cautiousness before clinical application. Thus, despite proof-of-concept studies of anti-inflammatory treatment effects in depression, important challenges remain to be investigated. Within this paper, we review...

    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. PMID:20645831

    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. PMID:25532284

    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.

    Freeze-dried inclusion complex of ellagic acid/β-cyclodextrin (EACD) was investigated both in solution and solid state by means of aqueous solubility, in vitro dissolution, absorption, fluorescence, Fourier transform infrared spectroscopy (FTIR), powder X-ray diffractometry (XRD), scanning electron microscopy (SEM), nuclear magnetic resonance (NMR) and molecular modeling methods. The phase solubility study showed that ellagic acid formed 1:2 stoichiometric inclusion complex with β-cyclodextrin (β-CD). The FTIR study indicates that carbonyl group of ellagic acid interact with β-CD. The NMR results demonstrate that ellagic acid was partly included into the β-CD from the wider side of the cavity. Molecular modeling studies revealed that hydrogen bonding interactions played an important role in the inclusion process and higher negative values for the complexation energies imply that 1:2 complex was more stable than 1:1 complex. The solubility and in vitro dissolution of ellagic acid was significantly enhanced by complexation with β-CD as compared to the free ellagic acid. Additionally, the complexation of EACD positively influences it's in vitro anti-inflammatory activity by protecting from protein denaturation and lysis of erythrocyte membrane.

    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.

    The aims of this study were to develop strains of lactic acid bacteria (LAB) having both immunomodulatory and antioxidant properties and to evaluate their anti-inflammatory effects both in vitro, in different cellular models, and in vivo, in a mouse model of colitis. Different Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus strains were cocultured with primary cultures of mononuclear cells. Analysis of the pro- and anti-inflammatory cytokines secreted by these cells after coincubation with candidate bacteria revealed that L. delbrueckii subsp. bulgaricus CRL 864 and S. thermophilus CRL 807 display the highest anti-inflammatory profiles in vitro. Moreover, these results were confirmed in vivo by the determination of the cytokine profiles in large intestine samples of mice fed with these strains. S. thermophilus CRL 807 was then transformed with two different plasmids harboring the genes encoding catalase (CAT) or superoxide dismutase (SOD) antioxidant enzymes, and the anti-inflammatory effects of recombinant streptococci were evaluated in a mouse model of colitis induced by trinitrobenzenesulfonic acid (TNBS). Our results showed a decrease in weight loss, lower liver microbial translocation, lower macroscopic and microscopic damage scores, and modulation of the cytokine production in the large intestines of mice treated with either CAT- or SOD-producing streptococci compared to those in mice treated with the wild-type strain or control mice without any treatment. Furthermore, the greatest anti-inflammatory activity was observed in mice receiving a mixture of both CAT- and SOD-producing streptococci. The addition of L. delbrueckii subsp. bulgaricus CRL 864 to this mixture did not improve their beneficial effects. These findings show that genetically engineering a candidate bacterium (e.g., S. thermophilus CRL 807) with intrinsic immunomodulatory properties by introducing a gene expressing an antioxidant enzyme enhances its anti-inflammatory

    Full Text Available Capsazepine, an antagonist of capsaicin, is discovered by the structure and activity relationship. In previous studies it has been found that capsazepine has potency for immunomodulation and anti-inflammatory activity and emerging as a favourable target in quest for efficacious and safe anti-inflammatory drug. Thus, a 2D quantitative structural activity relationship (QSAR model against target tumor necrosis factor-α (TNF-α was developed using multiple linear regression method (MLR with good internal prediction (r2 = 0.8779 and external prediction (r2pred = 0.5865 using Discovery Studio v3.5 (Accelrys, USA. The predicted activity was further validated by in vitro experiment. Capsazepine was tested in lipopolysaccharide (LPS induced inflammation in peritoneal mouse macrophages. Anti-inflammatory profile of capsazepine was assessed by its potency to inhibit the production of inflammatory mediator TNF-α. The in vitro experiment indicated that capsazepine is an efficient anti-inflammatory agent. Since, the developed QSAR model showed significant correlations between chemical structure and anti-inflammatory activity, it was successfully applied in the screening of forty-four virtual derivatives of capsazepine, which finally afforded six potent derivatives, CPZ-29, CPZ-30, CPZ-33, CPZ-34, CPZ-35 and CPZ-36. To gain more insights into the molecular mechanism of action of capsazepine and its derivatives, molecular docking and in silico absorption, distribution, metabolism, excretion and toxicity (ADMET studies were performed. The results of QSAR, molecular docking, in silico ADMET screening and in vitro experimental studies provide guideline and mechanistic scope for the identification of more potent anti-inflammatory & immunomodulatory drug.

    Bromelain-loaded katira gum nanoparticles were synthesized using 3 level optimization process and desirability approach. Nanoparticles of the optimized batch were characterized using particle size analysis, zeta potential, transmission electron microscopy and Fourier-transform infrared spectroscopy. Investigation of their in vivo anti-inflammatory activity by employing carrageenan induced rat-paw oedema method showed that encapsulation of bromelain in katira gum nanoparticles substantially enhanced its anti-inflammatory potential. This may be attributed to enhanced absorption owing to reduced particle size or to protection of bromelain from acid proteases. PMID:27083339

    Objective: To study the anti-inflammatory activity and tissue distribution patterns of intravenousemulsion of dexamethasone acetate in mice. Methods: The anti-inflammatory solution for injection andLimethasone(Jepanese product) given intravenously were evaluated by using the preformed carrageenan granulomapouch method in rats. Results: The anti-inflammatory activity of dexamethasone acetate emulsion at low dose of 0.05mg.kg1 was as potent as dexamethasone sodium phosphate solution at high dose of 0.3 mg.kg1. The distributionpatterns in mice tissues of [3H]dexamethasone acetate emulsion and [3H]dexamethasone sodium phosphate solution inmice were markedly different. Dexamethasone acetate emulsion showed a much higher concentration in the liver,spleen, lung, and inflamed tissues, whereas dexamethasone sodium phosphate had a high concenti,mon in themuscles of vastus lateralis. These results may indicate that dexamethasone incoporated in lipid emulsion was taken upby the reticuloendothelial system and inflammatory cells much more than dexamethasone sodium phosphate solution.Conclusion: When dexamethasone acetate was incorporated in emulsion, the distribution patterns in tissues werechanged and they had a stronger anti-inflammatory activity.

    Objective: To study detail pharmacognosy and anti-inflammatory activity of Callistemonlanceolatus (C. lanceolatus) leaf. Methods: Leaf sample was studied by organoleptic, macroscopical, microscopical, phytochemical and other WHO recommended methods for standardizations. The methanolic leaf extract of the plant was also screened for anti-inflammatory activity on carrageenan-induced paw edema in rat at doses of 200 and 400 mg/kg, orally. The detail pharmacognostic study of the C. lanceolatus leaf was carried out to lay down the standards which could be useful in future experimental studies. Results: C. lanceolatus methanolic leaf extract showed significant (P<0.05) anti-inflammatory activity at doses of 200 mg/kg and 400 mg/kg. This significant anti-inflammatory of C. lanceolatus methanolic leaf extract at the dose of 400 mg/kg was comparable with diclofenac sodium. Conclusions: The pharmacognostic profile of the C. lanceolatus leaf is helpful in standardization for quality, purity and sample identification. The methanolic extract at a dose of 400 mg/kg shows a significant activity in comparison with the standard drug diclofenac sodium (50 mg/kg).

    A novel dexamethasone palmitate liposomal long-circulating (DPL long-circulating) drug delivery system was established. The DPL long-circulating and DPL (dexamethasone palmitate liposomal) systems were prepared by film-distributed extrusion with phospholipid and cholesterol. The formulation stability of DPL long-circulating and DPL were investigated. The anti-inflammatory activity and acute toxicity of DPL long-circulating, DPL and dexa- methasone sodium phosphate injection (DSP) were evaluated with mice. The DPL long-circulating systems were successfully prepared by film-distributed extrusion methods. The experimental results showed that the DPL long-circulating had uniform particle size and stable property. The DPL long-circulating and DPL showed stronger anti-inflammatory effect than DSP in an anti-inflammatory test. Acute toxicity tests showed that DSP injection had lower toxicity than the DPL long-circulating and DPL, which suggested that DPL long-circulating and DPL had higher bioavailability with passive targeting efficacy of liposomes. The DPL long-circulating formulation product can meet quality requirement. This formulation had stronger anti-inflammatory effect and higher acute toxicity.

    2013-01-01

    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.

    Valeriana wallichii DC (Valerianaceae) is one of the most widely used traditional remedies for various complications associated with nervous system and digestion. No antimicrobial and anti-inflammatory studies have so far been carried out on the aerial parts of the plant. The present work was focused to evaluate the antimicrobial (antifungal and antibacterial) and anti-inflammatory properties of V. wallichii using reported methods. Chloroform fraction (VW-2) and hexane fraction (VW-3) exhibited significant activity against S. aureus and B. subtilus, respectively. The chloroform fraction (VW-2) showed significant activity against S. aureus with 0.27 mg/ml MIC, where 0.31 mg/ml MIC was deduced for VW-3 fraction against B. subtilus. VW-3 fraction was also found to be the most potent inhibitor of M. canis, showing 70% inhibition with an MIC value of 0.19 mg/ml. Considerable inhibitory activity was also observed for VW-2 and water fraction (VW-6) against M. canis and A. flavus. A remarkable anti-inflammatory like activity was observed for the crude extract at a dose of 200 mg/kg at all observed durations. Other doses of the sample also showed excellent activity. Looking to these results it may be concluded that V. wallichii may be a potential source for activity guided isolation of natural products with antimicrobial and anti-inflammatory-like properties.

    Pistacia vera L., a member of Anacardiaceae family, has been used for sedation and analgesia in traditional medicine. In this study, the antinociceptive and anti-inflammatory effects as well as acute toxicity of the aqueous and ethanolic extracts of P. vera leaves were investigated in mice. The antinociceptive activity was studied using hot plate and writhing tests. The effect of the extracts against acute inflammation was determined using xylene-induced ear edema and the activity of the extracts, against chronic inflammation, was assessed using the cotton pellet test. The LD50 values of the infusion and maceration extracts were 0.8 g/Kg and 0.79 g/Kg, respectively. The aqueous and ethanolic maceration extracts of the P. vera leaves at the doses of 0.4 g/Kg and 0.5 g/Kg (IP), respectively, showed antinociceptive effects. The pretreatment of naloxone (2 mg/Kg, SC) inhibited the activities of extracts in hot plate test, but naloxone at the same dose could not inhibit the antinociceptive activity in writhing test. The extracts also showed anti-inflammatory effects in acute and chronic anti-inflammatory tests. The ethanolic extract was as effective as diclofenac in both inflammatory tests. The aqueous and ethanolic extracts of P. vera leaves demonstrated central and peripheral antinociceptive activities dose-dependently and the central effect may be mediated by opioid system. The extracts also demonstrated anti-inflammatory effects against acute and chronic inflammation. PMID:24250418

    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.

  8. Anti-inflammatory effects of nicotine in obesity and ulcerative colitis

    2011-08-01

    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.

    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.

    Full Text Available ABESTRACT: Introduction & objective: Inflammation is a body defensive response to the endogenous and exogenous stimulators such as chemical, radiation, trauma and invasive microorganism, which result pain and tissue necrosis. 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.

    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. PMID:26579406

    Full Text Available Andrographolide (AG is an abundant component of plants of the genus Andrographis and has a number of beneficial properties including neuroprotective, anticancer, anti-inflammatory, and antidiabetic effects. Despite numerous pharmacological studies, the precise mechanism of AG is still ambiguous. Thus, in the present study, we investigated the molecular mechanisms of AG and its target proteins as they pertain to anti-inflammatory responses. AG suppressed the production of nitric oxide (NO and prostaglandin E2 (PGE2, as well as the mRNA abundance of inducible NO synthase (iNOS, tumor necrosis factor-alpha (TNF-α, cyclooxygenase (COX-2, and interferon-beta (IFN-β in a dose-dependent manner in both lipopolysaccharide- (LPS- activated RAW264.7 cells and peritoneal macrophages. AG also substantially ameliorated the symptoms of LPS-induced hepatitis and EtOH/HCl-induced gastritis in mice. Based on the results of luciferase reporter gene assays, kinase assays, and measurement of nuclear levels of transcription factors, the anti-inflammatory effects of AG were found to be clearly mediated by inhibition of both (1 extracellular signal-regulated kinase (ERK/activator protein (AP-1 and (2 IκB kinase ε (IKKε/interferon regulatory factor (IRF-3 pathways. In conclusion, we detected a novel molecular signaling pathway by which AG can suppress inflammatory responses. Thus, AG is a promising anti-inflammatory drug with two pharmacological targets.

    Full Text Available Acacia suma (Fabaceae is a medium sized erect tree found in the greater part of India. Present study was carried out for evaluation of ethanolic extract of stem bark of Acacia suma (EEAS at 200 and 400 mg/kg, p.o. for analgesic, anti-inflammatory and antipyretic activity. EEAS was screened for analgesic activity by writhing, tail flick, tail immersion and hot plate method in mice.  The anti-inflammatory activity by acute carrageenan induced paw oedema and chronic Freund’s adjuvant arthritis models in rats. The antipyretic activity was evaluated using Brewer’s yeast induced pyrexia in rabbits. Acute toxicity in mice was found to be higher than 2000 mg/kg., p.o.  Analgesic activity revealed that test dose of 400 mg/kg, p.o., had significant activity in various tested models. Anti-inflammatory studies at 200 and 400 mg/kg., p.o., of extract showed significant activity (P<0.01.  The extract showed significant (P<0.01 effect on yeast-induced fever in rabbits in dose dependant manner. Preliminary phytochemical tests revealed presence of carbohydrates, tannins, alkaloids, saponins and phenolic compounds in the ethanol extract of A. suma bark. The present study therefore provides scientific base for its use in the folklore remedies as an analgesic, anti-inflammatory and antipyretic properties of natural origin.

    Full Text Available Context: Acanthopanax trifoliatus is a ginseng-like plant, which has been widely used to treat various diseases including inflammatory-related diseases. Aims: The present study has been designed to investigate the anti-inflammatory and anti-hyperalgesic effects of various fractions of Acanthopanax trifoliatus leaves ethanolic extract in rats. Materials and Methods: Anti-inflammatory activity was studied by using carrageenan-induced edema on rat paw whilst anti-hyperalgesic was assessed by using carrageenan-evoked thermal hyperalgesia on plantar test. Statistical Analysis Used: Data were analyzed using Student t-test to compare with control.Multiple comparisons for difference between control and extract-treated groups were evaluated by Tukey HSD (Honestly Significant Difference test. P values less than 0.05 (P < 0.05 is considered significant. Results: Among three different fractions i.e., hexane, dichloromethane, and methanol tested, methanolic fraction displayed the most potent fraction amongst those three. It gave significant anti-inflammatory effect at highest dose, 500 mg/kg, with 77.24% of inhibition. Whilst for anti-hyperalgesic activity, methanolic fraction showed the highest efficacy at 375 mg/kg. Administration of methanolic fraction of Acanthopanax trifoliatus inhibited paw edema in a dose- dependent manner. The inhibition for both activities might be due to possible composition of polar compounds, which are flavonoids and phenolics content. Conclusions: Methanol fraction of Acanthopanax trifoliatus leaves has potential effect as anti-inflammatory and anti-hyperalgesia in acute inflammation model.

    The use of chitosan as an excipient in oral formulations, as a drug delivery vehicle for ulcerogenic anti-inflammatory drugs and as base in polyelectrolyte complex systems, to prepare solid release systems as sponges was investigated. The preparation by double emulsification of chitosan hydrogels carrying diclofenac, acetyl-salycilic acid and hydrocortisone acetate as anti-inflammatory drugs is reported. The concentration of anti-inflammatory drug in the chitosan hydrogel generating the sponges was 0.08 mmol. Chitosan-drug loaded sponges with anti-inflammatory drugs were prepared by freeze-drying at -60 °C and 0.009 atm. Structural investigations of the solid formulations were done by Fourier-transformed infrared and ultraviolet-visible spectroscopy, spectrofluorimetry, differential scanning calorimetry and X-ray diffractometry. The results indicated that the drug molecules are forming temporary chelates in chitosan hydrogels and sponges. Electron paramagnetic resonance demonstrates the presence of free radicals in a wide range and the antioxidant activity for chitosan-drug supramolecular cross-linked assemblies.

    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. PMID:26247152

    Full Text Available This work studied the anti-inflammatory activities of the hydroalcoholic extracts (HAEs from Erythrina velutina Willd. (Ev and E. mulungu Mart. ex Benth. (Em in the carrageenan- and dextran-induced mice hind paw edema models. These medicinal plants belonging to the Fabaceae family are used in some Brazilian communities to treat pain, inflammation, insomnia and disorders of the central nervous system. In the present work, the extracts were administered orally in male mice at the doses of 200 or 400 mg/kg. In the carrageenan-induced test, only Em showed anti-inflammatory activity, decreasing the paw edema, at the doses of 200 and 400 mg/kg. No effect was observed with Ev in this model. On the other hand, in the dextran model, Ev demonstrated anti-inflammatory effect, showing decrease of the paw edema at the 1, 2, 3, 4 and 24th h. Em (200 or 400 mg/kg presented anti-inflammatory effect at the 2, 3 and 4th h after administration of dextran, as compared to control. In conclusion, the work showed that Ev and Em present anti-edematous actions, which possibly occurs by distinct mechanisms. While Ev seems to interfere especially in inflammatory processes in which mast cells have an important role, Em exerts greater activity in the inflammatory process that depends mainly on polymorphonuclear leucocytes. However, further studies are needed to determine the exact mechanism of action of the species investigated.

    Full Text Available 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 E 2 (PGE 2 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 PGE 2 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.

    Full Text Available Curcuma longa is widely known for its anti-inflammatory activity in traditional system of medicine for centuries and has been scientifically validated extensively. The present study was conducted to evaluate the anti-inflammatory activity of curcuminoids and oil-free aqueous extract (COFAE of C. longa and compare it with that of curcuminoids and turmerones (volatile oil, the bioactive components of C. longa that are proven for the anti-inflammatory potential. The activity against inflammation was evaluated in xylene-induced ear edema, cotton pellet granuloma models in albino Swiss mice and albino Wistar rats, respectively. The results showed that COFAE of C. longa at three dose levels significantly (P≤0.05 inhibited inflammation in both models, as evidenced by reduction in ear weight and decrease in wet as well as dry weights of cotton pellets, when compared to the vehicle control. The COFAE of C. longa showed considerable anti-inflammatory effects against acute and chronic inflammation and the effects were comparable to those of curcuminoids and turmerones.

    The immunomodulatory activity of linezolid has recently been reported using in vitro experimental models. However, the anti-inflammatory activity of linezolid has not yet been demonstrated using in vivo experimental models. Therefore, the aim of the present study was to demonstrate the anti-inflammatory activity of linezolid and other anti-MRSA agents using the carrageenan-induced rat paw edema model. The pretreatment with 50 mg/kg linezolid significantly suppressed edema rates, compared with control (5% glucose), with edema rates at 0.5 and 3 h after the administration of carrageenan being 17.3 ± 3.5 and 30.8 ± 3.0%, respectively. On the other hand, edema rates were not suppressed by the pretreatments with 50 mg/kg vancomycin, teicoplanin, arbekacin, and daptomycin. Furthermore, we demonstrated that linezolid exhibited anti-inflammatory activity in a concentration-dependent manner. These effects were observed at linezolid concentrations that are achievable in human serum with conventional dosing. In conclusion, the results of the present study suggest that the anti-inflammatory activities of linezolid, in addition to its antimicrobial effects, have a protective effect against destructive inflammatory responses in areas of inflammation.

    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.

    Mulberry tree twigs (Ramulus mori) contain large amounts of oxyresveratrols and have traditionally been used as herbal medicines because of their anti-inflammatory properties. However, the signaling mechanism by which R. mori exerts its anti-inflammatory action remains to be elucidated. In this study, we observed that R. mori ethanol extracts (RME) exerted an inhibitory effect on the lipopolysaccharide (LPS)-induced production of the pro-inflammatory cytokine interleukin-6 (IL-6) in Raw264.7 macrophage cells. Additionally, RME inhibited IL-6 production by blocking the leukotriene B4 receptor- 2 (BLT2)-dependent-NADPH oxidase 1 (NOX1)-reactive oxygen species (ROS) cascade, leading to anti-inflammatory activity. Finally, RME suppressed the production of the BLT2 ligands LTB4 and 12(S)-HETE by inhibiting the p38 kinase- cytosolic phospholipase A2-5-/12-lipoxygenase cascade in LPS-stimulated Raw264.7 cells. Overall, our results suggest that RME inhibits the 'BLT2 ligand-BLT2'-linked autocrine inflammatory axis, and that this BLT2-linked cascade is one of the targets of the anti-inflammatory action of R. mori.

    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 root of Morinda officinalis (Rubiaceae) is used to treat rheumatoid arthritis and impotence in the traditional Oriental medicine. To identify the antinociceptive anti-inflammatory components of this crude drug, we adopted an activity-directed fractionation approach. The active fraction of the BuOH extract of M. officinalis root was subjected to silica gel and ODS column chromatography to yield two diterpenes, compounds 1 and 2 and these were identified as monotropein and deacetylasperulosidic acid, respectively. The iridoid glycoside, monotropein, was tested for its anti-inflammatory antinociceptive effects using hot plate- and writhing antinociceptive assays and by using carrageenan-induced anti-inflammatory assays in mice and rats. Pretreatment with monotropein (at 20, 30 mg/kg/d, p.o.) significantly reduced stretching episodes and prolonged action time in mice. It also significantly reduced acute paw edema by carrageenan in rats. These results indicate that monotropein contributes to the antinociceptive and anti-inflammatory action of Morinda officinalis root. PMID:16204945

    Full Text Available The flowers of the Chiliotrichum diffusum (G. Forst. Kuntze, Asteraceae, have long been used in traditional medicine and rituals. In this study, the anti-inflammatory and antinociceptive activities of a decoction of the flowers were evaluated and a phytochemical analysis was performed by HPLC-DAD. In order to evaluate the antinociceptive activity, the acetic acid-induced abdominal writhing and hot plate tests were used. The anti-inflammatory activity was evaluated using carrageenaninduced rat paw oedema. The decoction induced a significant anti-inflammatory effect (inhibition of 56.0% at 3 h and produced significant inhibition on nociception in the acetic acid test (ED50 35 mg/kg i.p.; ED50 709 mg/kg p.o.. In the hot plate test, the antinociceptive activity of the extract employed at 500 mg/kg i.p. was significantly suppressed by pretreatment with naloxone (5 mg/kg. HPLC analysis showed the presence of chlorogenic acid, caffeic acid, hyperoside, isoquercitrin, quercitrin, afzelin, quercetin, apigenin and kaempferol. The decoction of C. diffusum proved to have antinociceptive and anti-inflammatory effects that may be related to the presence of the flavones, flavonols and phenolic acids identified. The opiod system seems to be involved in the mechanism of antinociception of the extract.

AG suppressed the production of nitric oxide (NO) and prostaglandin E2 (PGE2), as well as the mRNA abundance of inducible NO synthase (iNOS), tumor necrosis factor-alpha (TNF- α ), cyclooxygenase (COX)-2, and interferon-beta (IFN- β ) in a dose-dependent manner in both lipopolysaccharide- (LPS-) activated RAW264.7 cells and peritoneal macrophages. AG also substantially ameliorated the symptoms of LPS-induced hepatitis and EtOH/HCl-induced gastritis in mice. Based on the results of luciferase reporter gene assays, kinase assays, and measurement of nuclear levels of transcription factors, the anti-inflammatory effects of AG were found to be clearly mediated by inhibition of both (1) extracellular signal-regulated kinase (ERK)/activator protein (AP)-1 and (2) I κ B kinase ε (IKK ε )/interferon regulatory factor (IRF)-3 pathways. In conclusion, we detected a novel molecular signaling pathway by which AG can suppress inflammatory responses. Thus, AG is a promising anti-inflammatory drug with two pharmacological targets.

    The purpose of the present study is to evaluate the effect of emu oil on bioavailability of curcumin when co-administered and to evaluate the property that enhances the anti-inflammatory potential of curcumin. Oral bioavailability of curcumin in combination with emu oil was determined by measuring the plasma concentration of curcumin by HPLC. The anti-inflammatory potential was evaluated in carrageenan-induced paw edema model (acute model) and in Freund's complete adjuvant (FCA)-induced arthritis model (chronic model) in male SD rats. The anti-inflammatory potential of curcumin in combination with emu oil has been significantly increased in both acute and chronic inflammatory models as evident from inhibition of increase in paw volume, arthritic score, and expression of pro-inflammatory cytokines. The increased anti-inflammatory activity in combination therapy is due to enhanced bioavailability (5.2-fold compared to aqueous suspension) of curcumin by emu oil. Finally, it is concluded that the combination of emu oil with curcumin will be a promising approach for the treatment of arthritis. PMID:25028100

    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.

    AMP-activated kinase (AMPK) is a cellular energy sensor, which is activated in stages of increased adenosine triphosphate (ATP) consumption. Its activation has been associated with a number of beneficial effects such as decrease of inflammatory processes and inhibition of disease progression of diabetes and obesity. A recent study suggested that salicylate, the active metabolite of the non-steroidal anti-inflammatory drug (NSAID) acetyl-salicylic acid (aspirin), is able to activate AMPK pharmacologically. This observation raised the question whether or not other NSAIDs might also act as AMPK activators and whether this action might contribute to their cyclooxygenase (COX)-independent anti-inflammatory properties. In this study, we investigated mouse and human neuronal cells and liver tissue of mice after treatment with various NSAIDs. Our results showed that the non-selective acidic NSAIDs ibuprofen and diclofenac induced AMPK activation similar to aspirin while the COX-2 selective drug etoricoxib and the non-opioid analgesic paracetamol, both drugs have no acidic structure, failed to activate AMPK. In conclusion, our results revealed that AMPK can be activated by specific non-steroidal anti-inflammatory drugs such as salicylic acid, ibuprofen or diclofenac possibly depending on the acidic structure of the drugs. AMPK might therefore contribute to their antinociceptive and anti-inflammatory properties. PMID:26049010

    Long-term use of nonsteroidal antiinflammatory drugs (NSAIDs) may cause serious side effects such as gastric mucosal damage. Resveratrol, a naturally dietary polyphenol, exhibited anti-inflammatory activity and a protective effect against gastric mucosa damage induced by NSAIDs. In this regard, we synthesized a series of resveratrol-based NSAIDs derivatives and evaluated their anti-inflammatory activity against nitric oxide (NO) overproduction in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. We identified mono-substituted resveratrol-ibuprofen combination 21 as the most potent anti-inflammatory agent, which is more active than a physical mixture of ibuprofen and resveratrol, individual ibuprofen, or individual resveratrol. In addition, compound 21 exerted potent inhibitory effects on the LPS-induced expression of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β). Furthermore, compound 21 significantly increased the survival rate in an LPS-induced acute inflammatory model and produced markedly less gastric damage than ibuprofen. It was found that compound 21 may be a potent anti-inflammatory agent for the treatment of inflammation-related diseases. PMID:27009373

    Inflammation, especially chronic inflammation, is directly involvement in the pathogenesis of many diseases including cancer. An effective approach for managing inflammation is to employ chemicals to block activation of nuclear factor-κB (NF-κB), a key regulator for inflammatory processes. Piperlongumine (piplartine, PL), an electrophilic molecule isolated from Piper longum L., possesses excellent anti-cancer and anti-inflammatory properties. In this study, a new PL analogue (PL-0N) was designed by replacing nitrogen atom of lactam in PL with carbon atom to increase its electrophilicity and thus anti-inflammatory activity. It was found that PL-0N is more potent than the parent compound in suppressing lipopolysaccharide (LPS)-induced secretion of nitric oxide and prostaglandin E2 as well as expression of inducible nitric oxide synthase and cyclooxygenase-2 in RAW264.7 macrophages. Mechanistic investigation implies that PL-0N exerts anti-inflammatory activity through inhibition of LPS-induced NF-κB transduction pathway, down-regulation of LPS-induced MAPKs activation and impairment of proteasomal activity, but also enhancement of LPS-induced autophagy; the inhibition of NF-κB by PL-0N is achieved at various stages by: (i) preventing phosphorylation of IKKα/β, (ii) stabilizing the suppressor protein IκBα, (iii) interfering with the nuclear translocation of NF-κB, and (iv) inhibiting the DNA-binding of NF-κB. These data indicate that nitrogen-atom-lacking pattern is a successful strategy to improve anti-inflammatory property of PL, and that the novel molecule, PL-0N may be served as a promising lead for developing natural product-directed anti-inflammatory agents.

    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.

    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. PMID:25338213

    Full Text Available Abstract Background The respiratory epithelium plays a central role in the inflammatory response in asthma and other diseases. Methoxyphenolic compounds are purported to be effective anti-inflammatory agents, but their effects on the airway epithelium have not been well characterized. Methods Human airway cells were stimulated with TNF-α in the presence or absence of 4-substituted methoxyphenols and resveratrol. The expression of various cytokines was measured by qPCR, ELISAs, and protein arrays. Reactive oxygen species (ROS production was measured with a reactive fluorescent probe (3',6'-diacetate-2',7'-dichlorofluorescein. Activation of NF-κB was measured by nuclear translocation and phosphorylation. Ribonuclear protein association with mRNA was assessed with a biotin-RNA affinity isolation assay. Results Multiple inflammatory mediators were inhibited by methoxyphenols, including: CCL2, CCL5, IL-6, IL-8, ICAM-1, MIF, CXCL1, CXCL10, and Serpin E1. IC50 values were obtained for each compound that showed significant anti-inflammatory activity: diapocynin (20.3 μM, resveratrol (42.7 μM, 2-methoxyhydroquinone (64.3 μM, apocynin (146.6 μM, and 4-amino-2-methoxyphenol (410 μM. The anti-inflammatory activity did not correlate with inhibition of reactive oxygen species production or NF-κB activation. However, methoxyphenols inhibited binding of the RNA-binding protein HuR to mRNA, indicating that they may act post-transcriptionally. Conclusions Methoxyphenols demonstrate anti-inflammatory activity in human airway cells. More potent compounds that act via similar mechanisms may have therapeutic potential as novel anti-inflammatory agents.

    Full Text Available The aim of this study was to investigate the anti-inflammatory potential of an ethanolic root extract (ERE of Ixora coccinea, Linn (Rubiaceae in rats by oral administration (500, 1000 and 1500 mg/kg. This was carried out by using carrageenan induced paw edema (acute inflammatory model and cotton pellet granuloma tests (chronic inflammatory model. In the former all the doses of ERE tested caused a significant (p < 0.05 to 0.001 and marked reduction in paw edema (28-59% compared to control at each time point measured. Overall, this anti-inflammatory effect seemed dose related. Indomethacin also impaired the edema formation, but this anti-inflammatory effect was much stronger (77-90%. In the latter test, ERE caused a significant (p < 0.05 and marked inhibition (36.1% of granuloma weight as compared to control (control vs. treatment: 29.2±9.6 vs. 18.6±7.1 mg. Collectively, these data show promising anti-inflammatory activity against both acute and chronic inflammation. ERE induced a significant (p < 0.05 and profound impairment by (42.6% of the area of wheal formed by the subcutaneous injection of histamine was comparable to that produced by Chlorpheniramine. It also showed promising antioxidant activity compared to Butylated hydroxyl toluene (BHT as control and dose dependent (r2 =0.9; p < 0.05 that can account for its anti-inflammatory potential. In addition, inhibition of prostaglandins and bradykinins may play a role.

    Anti-inflammatory, analgesic, and anti-pyretic activities of orally administered etofenamate, the diethylene glycol ester of flufenamic acid, were investigated in experimental animals. Against acetic acid-induced vascular permeability in mice and ultra-violet light-induced erythema in guinea pigs, etofenamate produced a dose related inhibition at doses of 40--320 mg/kg and 5--20 mg/kg, respectively. In rats, felt-pellet-induced granuloma formation and adjuvant-induced arthritis were significantly inhibited by repeated administration of etofenamate at doses of 20 mg/kg/day for 5 days and 40 mg/kg/day for 21 days, respectively. Etofenamate showed an inhibitory activity on the squeak response caused by flexing and extending the silver nitrate-induced arthritic joint in rats; and it produced a dose related anti-writhing activity at doses of 50--300 mg/kg and 10--80 mg/kg in mice and rats, respectively, in the acetic acid-induced writhing test. Etofenamate showed a significant anti-pyretic activity at doses of 0.2 mg/kg or more. These potencies of etofenamate were 0.5 to 1.6 times those of flufenamic acid. In particular, the anti-erythema, anti-arthritis, and anti-pyretic activities of etofenamate were approximately equivalent to or superior to those of flufenamic acid. From these results, it was suggested that etofenamate given orally, like other non-steroidal anti-inflammatory drugs, showed anti-inflammatory, analgesic, and anti-pyretic activities in experimental animals.

    Full Text Available Abstract Background Several studies have identified use of non-steroidal-anti-inflammatory drugs and statins for prevention of dementia, but their efficacy in slowing progression is not well understood. Cerebrovascular disturbances are common pathological feature of Alzheimer’s disease. We previously reported chronic ingestion of saturated fatty acids (SFA compromises blood–brain barrier (BBB integrity resulting in cerebral extravasation of plasma proteins and inflammation. However, the SFA-induced parenchymal accumulation of plasma proteins could be prevented by co-administration of some cholesterol lowering agents. Restoration of BBB dysfunction is clinically relevant, so the purpose of this study was to explore lipid-lowering agents could reverse BBB disturbances induced by chronic ingestion of SFA’s. Methods Wild-type mice were fed an SFA diet for 12 weeks to induce BBB dysfunction, and then randomised to receive atorvastatin, pravastatin or ibuprofen in combination with the SFA-rich diet for 2 or 8 weeks. Abundance of plasma-derived immunoglobulin-G (IgG and amyloid-β enriched apolipoprotein (apo-B lipoproteins within brain parenchyme were quantified utilising immunofluorescence microscopy. Results Atorvastatin treatment for 2 and 8 weeks restored BBB integrity, indicated by a substantial reduction of IgG and apo B, particularly within the hippocampus. Pravastatin, a water-soluble statin was less effective than atorvastatin (lipid-soluble. Statin effects were independent of changes in plasma lipid homeostasis. Ibuprofen, a lipid-soluble cyclooxygenase inhibitor attenuated cerebral accumulation of IgG and apo B as effectively as atorvastatin. Our findings are consistent with the drug effects being independent of plasma lipid homeostasis. Conclusion Our findings suggest that BBB dysfunction induced by chronic ingestion of SFA is reversible with timely introduction and sustained treatment with agents that suppress 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.

    Piperlongumine (PL) and its derivatives were synthesized by the direct reaction between acid chloride of 3,4,5-trimethoxycinnamic acid and various amides/lactams. Later their anti-inflammatory effects were evaluated in lipopolysaccharide (LPS)-induced RAW-264.7 macrophages. Of the piperlogs prepared in this study, the maximum (91%) inhibitory activity was observed with PL (IC50=3 μM) but showed cytotoxicity whereas compound 3 (IC50=6 μM) which possess α,β-unsaturated γ-butyrolactam moiety offered good level (65%) of activity with no cytotoxicity. This study revealed that amide/lactam moiety connected to cinnamoyl group with minimum 3 carbon chain length and α,β-unsaturation is fruitful to show potent anti-inflammatory activity. PMID:25453809

    2014-01-01

    Unsaturated fatty acids are metabolized to reactive products that can act as pro- or anti-inflammatory signaling mediators. Electrophilic fatty acid species, including nitro- and oxo-containing fatty acids, display salutary anti-inflammatory and metabolic actions. Electrophilicity can be conferred by both enzymatic and oxidative reactions, via the homolytic addition of nitrogen dioxide to a double bond or via the formation of α,β-unsaturated carbonyl and epoxide substituents. The endogenous formation of electrophilic fatty acids is significant and influenced by diet, metabolic, and inflammatory reactions. Transcriptional regulatory proteins and enzymes can sense the redox status of the surrounding environment upon electrophilic fatty acid adduction of functionally significant, nucleophilic cysteines. Through this covalent and often reversible posttranslational modification, gene expression and metabolic responses are induced. At low concentrations, the pleiotropic signaling actions that are regulated by these protein targets suggest that some classes of electrophilic lipids may be useful for treating metabolic and inflammatory diseases.

    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. PMID:1891491

    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.

    Bergin, David A

    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.

    Benzoxazinones and quinazolinones have a wide spectrum of biological activity. In this paper we focused on studying the antimicrobial and anti-inflammatory activities of some newly synthesized benzoxazinone and quinazolinone derivatives. Thus we prepared 2-[α-benzoylaminostyryl]-6,8-dibromo-3,1-benzoxazin-4(H)-one 2 which underwent a reaction with primary and secondary amines, and hydrazine hydrate to give compounds 3, 4 and 5, respectively. Treatment of 2 with hydroxylamine hydrochloride, formamide and/or NaN3/AcOH afforded compounds 7, 8, 11 and 12, respectively. Also, compound 2 reacted with maleic anhydride, aromatic hydrocarbons and/or active methylene compounds to produce compounds 13, 15a-c and 16, respectively. Most of the newly synthesized compounds showed significant antimicrobial and anti-inflammatory activities comparable to ampicillin, mycostatine and indomethacin positive controls. PMID:26699093

    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.

The anti-inflammatory activity was tested by injecting different groups of rats (6 each) with formalin in hind paw and measuring the edema volume before and 1 h later formalin injection. Control group received saline i.p. The extracts treatment was injected i.p. in doses of 100 and 200 mg/kg 1 h before formalin administration. Indomethacin (30 mg/kg) was used as standard.Results:The results of preliminary phytochemical studies confirmed the presence of protein, lipid, carbohydrate, phenol, flavonoid, saponin, triterpenoid, alkaloid and anthraquinone in both extracts. Chromatography was performed on glass-backed silica gel 60 F254 HPTLC plates with the green solvents toluene: ethyacetate: glacial acetic acid (5:3:0.2, v/v/v) as mobile phase. HPTLC finger printing of AESF revealed major eight peaks with Rf values in the range of 0.28 to 0.80 and the dichloromethane revealed major 11 peaks with Rf values in the range of 0.12 to 0.76. The purity of sample was confirmed by comparing the absorption spectra at start, middle and end position of the band. Treatment of rats (i.p.) with AESF and dichloromethane in doses of 100 and 200 mg/kg inhibited singnificantly (P<0.05, n=6) formalin-induced inflammation by 50%, 55.9%, 45.5%, and 51.4%, respectively.Conclusions:HPTLC finger printing of AESF and dichloromethane of Maytenus obscura revealed eight major spots for alcoholic extracts and nine major spots for dichloromethane extracts.

    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.

    Full Text Available Activation of the cholinergic anti-inflammatory pathway, which relies on the α7nAchR (alpha 7 nicotinic acetylcholine receptor, has been shown to decrease proinflammatory cytokines. This relieves inflammatory responses and improves the prognosis of patients with experimental sepsis, endotoxemia, ischemia/reperfusion injury, hemorrhagic shock, pancreatitis, arthritis and other inflammatory syndromes. However, whether the cholinergic anti-inflammatory pathway has an effect on acute viral myocarditis has not been investigated. Here, we studied the effects of the cholinergic anti-inflammatory pathway on acute viral myocarditis.In a coxsackievirus B3 murine myocarditis model (Balb/c, nicotine and methyllycaconitine were used to stimulate and block the cholinergic anti-inflammatory pathway, respectively. Relevant signal pathways were studied to compare their effects on myocarditis, survival rate, histopathological changes, ultrastructural changes, and cytokine levels. Nicotine treatments significantly improved survival rate, attenuated myocardial lesions, and downregulated the expression of TNF-α and IL-6. Methyllycaconitine decreased survival rate, aggravated myocardial lesions, and upregulated the expression of TNF-α and IL-6. In addition, levels of the signaling protein phosphorylated STAT3 were higher in the nicotine group and lower in the methyllycaconitine group compared with the untreated myocarditis group.These results show that nicotine protects mice from CVB3-induced viral myocarditis and that methyllycaconitine aggravates viral myocarditis in mice. Because nicotine is a α7nAchR agonist and methyllycaconitine is a α7nAchR antagonist, we conclude that α7nAchR activation increases the phosphorylation of STAT3, reduces the expression of TNF-α and IL-6, and, ultimately, alleviates viral myocarditis. We also conclude that blocking α7nAchR reduces the phosphorylation of STAT3, increases the expression of TNF-α and IL-6, aggravating viral

  13. Chitosan drives anti-inflammatory macrophage polarisation and pro-inflammatory dendritic cell stimulation

    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.

    Many species of the genus Eucalyptus from the Myrtaceae family are used in Brazilian folk medicine for the treatment of various medical conditions such as cold, flue, fever, and bronchial infections. In the current investigation, we evaluated the analgesic and anti-inflammatory effects of essential oil extracts from three species of Eucalyptus employing various standard experimental test models. Using acetic acid-induced writhes in mice and hot plate thermal stimulation in rats, it was shown that the essential oils of Eucalyptus citriodora (EC), Eucalyptus tereticornis (ET), and Eucalyptus globulus (EG) induced analgesic effects in both models, suggesting peripheral and central actions. In addition, essential oil extracts from the three Eucalyptus species produced anti-inflammatory effects, as demonstrated by inhibition of rat paw edema induced by carrageenan and dextran, neutrophil migration into rat peritoneal cavities induced by carrageenan, and vascular permeability induced by carrageenan and histamine. However, no consistent results were observed for some of the parameters evaluated, both in terms of activities and dose-response relationships, reflecting the complex nature of the oil extracts and/or the assay systems used. Taken together, the data suggest that essential oil extracts of EC, ET, and EG possess central and peripheral analgesic effects as well as neutrophil-dependent and independent anti-inflammatory activities. These initial observations provide support for the reported use of the eucalyptus plant in Brazilian folk medicine. Further investigation is warranted for possible development of new classes of analgesic and anti-inflammatory drugs from components of the essential oils of the Eucalyptus species. PMID:14611892

    GPR120 (free fatty acid receptor-4) is a G protein-coupled receptor for medium- and long-chain unsaturated fatty acids, including ω-3 fatty acids. Recent studies have shown GPR120 to play cardinal roles in metabolic disorders via modulation of gut hormone secretion and insulin sensitivity and to exert anti-inflammatory effects in macrophages and adipose tissues. However, information on anti-inflammatory role of GPR120 at the level of intestinal epithelium is very limited. Current studies demonstrated differential levels of GPR120 mRNA and protein along the length of the human, mouse, and rat intestine and delineated distinct anti-inflammatory responses following GPR120 activation in model human intestinal epithelial Caco-2 cells, but not in model mouse intestinal epithelial endocrine cell line STC-1. In Caco-2 cells, GPR120 was internalized, bound to β-arrestin-2, and attenuated NF-κB activation in response to 30-min exposure to the agonists GW9508, TUG-891, or docosahexaenoic acid. These effects were abrogated in response to small interfering RNA silencing of β-arrestin-2. Treatment of STC-1 cells with these agonists did not induce receptor internalization and had no effects on NF-κB activation, although treatment with the agonists GW9508 or TUG-891 for 6 h augmented the synthesis and secretion of the gut hormone glucagon-like peptide-1 in this cell line. Our studies for the first time demonstrated a GPR120-mediated novel anti-inflammatory pathway in specific intestinal epithelial cell types that could be of therapeutic relevance to intestinal inflammatory disorders.

    Eupatilin (5,7-dihydroxy-3',4',6-trimethoxyflavone) is the major lipophilic flavonoid from Artemisia umbelliformis Lam. and Artemisia genipi Weber, two mountain wormwoods used for the production of the celebrated alpine liqueur genepy. The topical anti-inflammatory activity of eupatilin was investigated using the inhibition of the Croton-oil-induced dermatitis in the mouse ear as the end point. The oedematous response and the leukocyte infiltration were evaluated up to 48 h after the induction of phlogosis, comparing eupatilin with hydrocortisone and indomethacin as representatives of steroid and non-steroid anti-inflammatory drugs, respectively. At maximum development, eupatilin significantly reduced edema in a dose-dependent manner (ID(50) = 0.28 micromol/cm(2)), showing an anti-inflammatory potency comparable to that of indomethacin (ID(50) = 0.26 micromol/cm(2)) and only 1 order of magnitude lower than that of hydrocortisone (ID(50) = 0.03 micromol/cm(2)). Within 48 h, eupatilin (0.30 micromol/cm(2)) caused a global inhibition of the oedematous response (42%) higher than that of an equimolar dose of indomethacin (18%) and fully comparable to that of 0.03 micromol/cm(2) of hydrocortisone (55%). Moreover, the effect of eupatilin on the granulocytes infiltrate (32% inhibition) was similar to that of indomethacin (35% inhibition) and comparable to that of hydrocortisone (42% reduction), as confirmed by histological analysis. When our results are taken together, they show that eupatilin is endowed with potent in vivo topical anti-inflammatory activity, qualitatively similar to that of hydrocortisone and intermediate in terms of potency between those of steroid and non-steroid drugs.

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.

    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.

    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.

    Cashew apple is a tropical pseudofruit consumed as juice due to its excellent nutritional and sensory properties. In spite of being well known for its important antioxidant properties, the cashew apple has not been thoroughly investigated for its therapeutic potential. Thereby, this study evaluated the antioxidant capacity, anti-inflammatory, and wound-healing activities of cashew apple juice. Juices from ripe and immature cashew apples were analyzed for antioxidant, anti-inflammatory, and wound-healing properties. Those were evaluated in murine models of xylene-induced ear edema and wound excision. Swiss mice were treated with cashew juice by gavage. Edema thickness was measured and skin lesions were analyzed by planimetry and histology. Both antioxidant content and total antioxidant activity were higher in ripe cashew apple juice (RCAJ) than in unripe cashew apple juice (UNCAJ). The UNCAJ presented the main anti-inflammatory activity by a significant inhibition of ear edema (66.5%) when compared to RCAJ (10%). Moreover, UNCAJ also showed the best result for wound contraction (86.31%) compared to RCAJ (67.54%). Despite of higher antioxidant capacity, RCAJ did not promote better anti-inflammatory, and healing responses, which may be explained by the fact that treatment increased antioxidants level leading to a redox "imbalance" turning down the inflammatory response modulation exerted by reactive oxygen species (ROS). The results suggest that UNCAJ presents a greater therapeutic activity due to a synergistic effect of its phytochemical components, which improve the immunological mechanisms as well as an optimal balance between ROS and antioxidants leading to a better wound healing process.

    Endogenous carbon monoxide (CO) exerts anti-inflammatory effects. Tristetraprolin (TTP) is known to destabilize pro-inflammatory transcripts. Here we found that exogenous CO enhanced the decay of TNF-α mRNA and suppressed TNF-α expression in LPS-activated macrophages from wild-type (WT) mice. However, TTP deficiency abrogated the effects of exogenous CO. While CO treatment prior to DSS administration in WT mice significantly reduced inflammatory cytokine levels and colitis, it failed to reduc...

    Inflammation is a pivotal component of a variety of diseases, such as atherosclerosis and tumour progression. Various naturally occurring phytochemicals exhibit anti-inflammatory activity and are considered to be potential drug candidates against inflammation-related pathological processes. Capsicum baccatum L. var. pendulum (Willd.) Eshbaugh (Solanaceae) is the most consumed species in Brazil, and its compounds, such as capsaicinoids, have been found to inhibit the inflammatory process. However, the anti-inflammatory effects of C. baccatum have not been characterized. Thus, this study was designed to evaluate the effects of C. baccatum juice in animal models of acute inflammation induced by carrageenan and immune inflammation induced by methylated bovine serum albumin. Pretreatment (30 min) of rats with pepper juice (0.25-2.0 g kg(-1)) significantly decreased leucocyte and neutrophil migration, exudate volume and protein and LDH concentration in pleural exudates of a pleurisy model. This juice also inhibited neutrophil migration and reduced the vascular permeability on carrageenan-induced peritonitis in mice. C. baccatum juice also reduced neutrophil recruitment and exudate levels of pro-inflammatory cytokines TNF-alpha and IL-1beta in mouse inflammatory immune peritonitis. Furthermore, we demonstrated that the main constituent of C. baccatum juice, as extracted with chloroform, is capsaicin. In agreement with this, capsaicin was able to inhibit the neutrophil migration towards the inflammatory focus. To our knowledge, this is the first demonstration of the anti-inflammatory effect of C. baccatum juice and our data suggest that this effect may be induced by capsaicin. Moreover, the anti-inflammatory effect induced by red pepper may be by inhibition of pro-inflammatory cytokine production at the inflammatory site. PMID:18380920

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.

The purpose of this study was to compare the anti-inflammatory effect of ethanolic extract of Nigella sativa seeds with that of diclofenac sodium in albino rats. Method: This laboratory randomized controlled trial (RCT) was conducted in the Physiology Department, Services Institute of Medical Sciences (SIMS), Lahore. The study was carried out on 90 male albino rats. Five percent formalin in a dose of 50 meu was injected into sub-plantar surface of right hind paw of each rat to produce inflammation. The rats were randomly divided into three groups of thirty each. Group A was given normal saline (control); group B was given Nigella sativa seed extract; and group C received diclofenac sodium, as a reference drug. Increase in paw diameter, and total and differential leukocyte counts were measured as markers of inflammation. Results: Nigella sativa seeds extract caused significant (p<0.05) reduction in the paw inflammatory response in albino rats. The effect was longer in duration than the effect caused by diclofenac sodium; however, the extract was comparatively less potent than diclofenac sodium. The extract had no significant effect (p>0.05) on the total or differential leukocyte counts. Conclusion: Our results suggest that ethanolic extract of Nigella sativa seeds possesses potent anti-inflammatory effect, in albino rats however, this effect is comparatively less but prolonged than that produced by diclofenac sodium.

    Full Text Available Abstract Background Lonicera japonica Thunb. (Caprifoliaceae, a widely used traditional Chinese medicinal plant, is used to treat some infectious diseases and it may have uses as a healthy food and applications in cosmetics and as an ornamental groundcover. The ethanol extract of the flowering aerial parts of L. japonica (LJEE was investigated for its healing efficiency in a rat excision wound model. Methods Excision wounds were inflicted upon three groups of eight rats each. Healing was assessed by the rate of wound contraction in skin wound sites in rats treated with simple ointment base, 10% (w/w LJEE ointment, or the reference standard drug, 0.2% (w/w nitrofurazone ointment. The effects of LJEE on the contents of hydroxyproline and hexosamine during healing were estimated. The antimicrobial activity of LJEE against microorganisms was also assessed. The in vivo anti-inflammatory activity of LJEE was investigated to understand the mechanism of wound healing. Results LJEE exhibited significant antimicrobial activity against Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, Candida albicans, and Candida tropicalis. The ointment formulation prepared with 10% (w/w LJEE exhibited potent wound healing capacity as evidenced by the wound contraction in the excision wound model. The contents of hydroxyproline and hexosamine also correlated with the observed healing pattern. These findings were supported by the histopathological characteristics of healed wound sections, as greater tissue regeneration, more fibroblasts, and angiogenesis were observed in the 10% (w/w LJEE ointment-treated group. The results also indicated that LJEE possesses potent anti-inflammatory activity, as it enhanced the production of anti-inflammatory cytokines that suppress proinflammatory cytokine production. Conclusions The results suggest that the antimicrobial and anti-inflammatory activities of LJEE act synergistically to accelerate wound repair.

  6. Hemostimulating efficiency of non-steroid anti-inflammatory drugs under modified irradiation conditions

    International Nuclear Information System (INIS)

    Non-steroid anti-inflammatory drugs (NSAID) were found to have hemostimulating effect in mice after irradiation. This effect was rather definite under irradiation conditions modified by dose fractioning or radioprotective chemicals. NSAID application during fractionated irradiation with midlethal integral dose leads to almost complete recovery of bone marrow hemopoiesis by the 9th day of radiation illness. NSAID usage combined with chemical radioprotectors provides effective hemopoiesis stimulation leading to survival increase in animals, irradiated with absolutely lethal doses. (author)

    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.

    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.

    2015-08-01

    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.

    Daniel Closa; Yoshiharu Motoo; Juan L Iovanna

    2007-01-01

    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.

    The present study was designed to investigate the antioxidant, antinociceptive and anti-inflammatory activities of the ethanol extract from Ageratum fastigiatum branches. Phytochemical screening and total phenol and flavonoid contents were determined. The antioxidant activity was assessed by 2,2-diphenyl-1-pycrilhydrazin (DPPH) and iron reducing power methods. The antinociceptive effect was evaluated using the acetic acid-induced writhing, formalin, hot plate and tail immersion assays; while the carrageenan-induced paw edema and pleurisy tests were performed to examine the anti-inflammatory activity against acute inflammation. The extract revealed the presence of flavonoids, tannins, coumarins, terpenes, sterols and saponins. Expressive levels of total phenols and flavonoids and a promising antioxidant effect were quantified. At the doses of 50, 100 and 200 mg/kg, the extract inhibited the writhing, reduced both phases of paw licking time and increased the reaction time on the hot plate. In the tail immersion test, the extract (50, 100 and 200 mg/kg) caused a significant inhibition of pain. In these doses, the paw edema, exudate volume and leucocyte mobilization were significantly reduced. These results suggest that A. fastigiatum can be an active source of substances with antioxidant, antinociceptive and anti-inflammatory activities, adding scientific support to the appropriate use in the Brazilian folk medicine.
