title: Leukotrienes produced by incubation of dihomo-delta-linolenic acid with human polymorphonuclear leukocytes.
abstract: Two new leukotrienes, 8,15-dihydroxy-9,11,13-icosatrienoic acid (8,15-LTB3) and 14,15-dihydroxy-8,10,12-icosatrienoic acid (14,15-LTB3) were identified in incubations of human polymorphonuclear leukocytes with dihomo-delta-linolenic acid (8,11,14-icosatrienoic acid). The yield of these compounds was very low (0.5% of the total radioactivity) and did not increase with indomethacin alone or in combination with ionophore A-23187. Stereochemistry and biologic activity of the two leukotrienes remain to be established.
