Los prostanoides, una revolución autacoide/ The prostanoids, an autocoid revolution

Dominguez, Zury
2006-01-01

Resumen en español Durante el período de 1960 y los finales del siglo XX, distintos investigadores concentraron esfuerzos para comprender la regulación de la biosíntesis y el metabolismo de los Eicosanoides. Estas moléculas, de carácter autacoide, se originan de los ácidos grasos poliinsaturados de 20 átomos de C, de allí que su nombre se derive del prefijo griego EICO, veinte. Las acciones fisiológicas y en ciertas condiciones, fisiopatológicas, ejercidas por estas moléculas ocu (mas) rre en un orden de concentración mmolar o menor y permanecen activas por espacios de tiempo que fluctúan entre los segundos y los minutos. En ese fructífero período del siglo XX, se logró identificar: 1- el ácido araquidónico como el principal precursor de los eicosanoides, 2- el compartimiento de los fosfolípidos de membrana como el almacén celular del sustrato precursor y 3- a las fosfolipasas, como las enzimas requeridas para liberar al ácido graso precursor, que hace posible su acceso a la maquinaria enzimática de síntesis de eicosanoides. En función de su estructura molecular surgen dos grandes grupos de eicosanoides, el que agrupa a los cíclicos o prostanoides, cuyo precursor universal es la prostaglandina H (PGH), un endoperóxido cíclico sintetizado por la enzima prostaglandina endoperóxido sintasa, mejor conocida por su acrónimo, COX, de cicloxigenasa; y el que agrupa a los lineales: leucotrienos, lipoxinas, y epóxidos entre otros, que son el producto de distintas rutas enzimáticas incluyendo a la lipoxigenas y las citocromo oxidasas. Esta revisión presenta los hallazgos más importantes en la historia de los prostanoides. Resumen en inglés From 1960 to the end of the XX century, efforts from different laboratories were done to understand the regulation of eicosanoids biosynthesis and metabolism. These autacoids are synthesized from 20 C polyunsaturated fatty acids, from where they got the prefix EICO, twenty. The physiologic and in certain conditions pathphysiologic actions, requires ≤ mmolar concentrations remaining active for periods of time ranging from seconds to minutes. During this productive pe (mas) riod of the XX century it was possible to identify: 1- araquidonic acid as the main eicosanoid’s precursor, 2- the membrane phospholipids compartment as the cellular storage of the precursor fatty acid and 3- the phospholipases as the enzymes required to liberate the precursor fatty acid rending possible its access to the eicosanoids biosynthetic machinery. Two main groups of eicosanoids arrive on the scene, classified in function to its molecular structure, one that includes the cyclic or prostanoids, where the prostaglandin H (PGH) is the universal precursor, PGH is a cyclic endoperoxide synthesized by the enzyme prostaglandin endoperóxido synthase, better known by its acronym COX for cycloxygenase, and the other, linear eicosanoids:: leukotrienes, lypoxines, and epoxides which are products synthesized from different enzymatic pathways including the lypoxygenase and cytochrome oxidases. The most relevant findings in the history of the prostanoids are considered in this review.
