Definition

ChEBI: A C20 polyunsaturated fatty acid having three triple bonds in the 5-, 8- and 11-positions.

Biological Activity

5,8,11-eicosatriynoic acid is a selective inhibitor of lipoxygenases with id50 values of 24 μm and 340 μm for n-8 lipoxygenase and fatty acid cycle-oxygenase , respectively[1][2].fatty acid cycle-oxygenase and n-8 lipoxygenase catalyze the initial reactions which lead to the formation of three major arachidonic acid metabolites in human platelets. in several tissues, these two enzymes act concomitantly on arachidonic acid [1].5,8,11-eicosatriynoic acid (5,8,11-et) is a selective inhibitor of lipoxygenases with id50 values of 24 μm and 340 μm for n-8 lipoxygenase and fatty acid cycle-oxygenase, respectively. 5,8,11-eicosatriynoic acid was useful for studies on physiological and pathophysiological roles of 12 l-hydroxy-5,8,10,14-eicosatetraenoic acid formation in various tissues [1]. in mouse mastocytoma cells, 5,8,11-eicosatriynoic acid inhibited a23187 and l-cysteine induced leukotriene c (ltc4) biosynthesis with id50 value of 5 μm [2].
