Description and references

Important intermediate in a series of biosynthetic processes leading from arachidonic acid, q.v., to a number of biologically active compounds. First discovered during the transformation of arachidonic acid by rabbit peritoneal polymorphonuclear leukocytes: P. Borgeat et al., J. Biol. Chem. 251, 7816 (1976). Revised description: eidem, ibid. 252, 8772 (1977). It has also been found during metabolism of arachidonic acid by human peripheral blood polymorphonuclear leukocytes: P. Borgeat, B. Samuelsson, Proc. Natl. Acad. Sci. USA 76, 2148 (1979); and has been shown to be strongly chemotactic for human eosinophils and neutrophils: E. J. Goetzl et al., Immunology 39, 491 (1980); E. J. Goetzl, N. Engl. J. Med. 303, 822 (1980). 5-HETE is formed via 5-HPETE (5-hydroperoxy-6,8,11,14-eicosatetraenoic acid), a precursor of the leukotrienes, q.v.
