Common NamePGH3
DescriptionProstaglandin H3 (PGH3)can be enzymatically converted by platelets into thromboxane A3. Both PGH2 and thromboxane A2 aggregate human platelet-rich plasma. In contrast, PGH3 and thromboxane A3 do not. PGH3 and thromboxane A3 increase platelet cyclic AMP in platelet-rich plasma and thereby: (i) inhibit. aggregation by other agonists, (ii) block the ADP-induced release reaction, and (iii) suppress platelet phospholipase-A2 activity or events leading to its activation. PGI3 (A'7-prostacyclin; synthesized from PGH3 by blood vessel enzyme) and PGI2(prostacyclin) exert similar effects. Both compounds are potent coronary relaxants that also inhibit aggregation in human platelet-rich plasma and increase platelet adenylate cyclase activity. Prostaglandins are eicosanoids. The eicosanoids consist of the prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs) and lipoxins (LXs). The PGs and TXs are collectively identified as prostanoids. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes) and leukotrienes from leukocytes, hence the derivation of their names. All mammalian cells except erythrocytes synthesize eicosanoids. These molecules are extremely potent, able to cause profound physiological effects at very dilute concentrations. All eicosanoids function locally at the site of synthesis, through receptor-mediated G-protein linked signaling pathways.
