Stimulation of human polymorphonuclear leukocytes with the chemotactic peptide formylmethionylleucylphenylalanine led to the formation of a novel leukotriene: 5(S),12(R)-dihydroxy-6,8,10,14-eicosatetraen-1,20-dioic acid. This dihydroxydicarboxylic acid is derived from omega-oxidation of 5(S),12(R),dihydroxy-6,8,10,14-eicosatetradienoic acid (leukotriene B4). The intermediate 5(S),12(R),20-trihydroxy-6,8,10,14-eicosatetraenoic acid was also isolated from these incubations. The two metabolites of leukotriene B4 exhibit chemotactic properties for human polymorphonuclear leukocytes but are less active in this respect than the parent compound.
