5,8,11-Eicosatriynoic Acid
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].
