Metabolite Identification
Common Name6,15-Diketo,13,14-dihydro-PGF1a
Description6,15-diketo,13,14-dihydro-PGF1 alpha is a minor metabolite of prostacyclin (PGI2). Prostacyclin (PGI2) is one of the major vascular protectors against thrombosis and vasoconstriction, caused by thromboxane A(2). PGI2 inhibits platelet aggregation and vasoconstriction. PGI2 synthase (PGIS), a catalyst of PGI2 formation from prostaglandin H2, is widely distributed and predominantly found in vascular endothelial and smooth muscle cells. PGI2 plays an important cardioprotective role increasingly appreciated in recent years in light of adverse effects of COX-2 inhibitors in clinical trials. This cardioprotection is thought to be mediated, in part, by prostacyclin inhibition of platelet aggregation. Multiple lines of evidence suggest that prostacyclin additionally protects from cardiovascular disease by pleiotropic effects on vascular smooth muscle. PGI2 inhibits proliferation of cultured vascular SMCs by inhibiting cell cycle progression from G1 to S phase. Progression through G1 phase is regulated by the sequential activation of the G1 phase cyclin-dependent kinases (cdks). (PMID: 7000774 , 6231483 , 16303599 , 16533160 , 17073611 , 17164138 ).
