Chemical Synthesis Nicolaou_KC et al.
Metabolism When prostaglandin H2 reacts with thromboxane A synthase and the endoperoxide moiety is cleaved, the production of thromboxane A2 is accompanied by the formation of 12(S)-hydroxy-5,8,10-heptadecatrienoic acid in an almost equimolar amount liberating malondialdehyde Hamberg_M et al.. This compound is also a product of non-enxymatic degradation of prostaglandin H2 Nugteren_DH et al..
Biological Activity The compound stimulates chemotactic and chemokinetic activities of human polymorphonuclear leukocytes Goetzl_EJ et al..
