Metabolite Identification
Common NameProstaglandin E2 ethanolamide
Descriptionprostaglandin E2 ethanolamide is the major prostanoid product derived from anandamide. Incubation of anandamide with lysates and the intact cell line expressing COX-2 but not that of COX-1 produced prostaglandin E2 ethanolamide. This reaction demonstrates the existence of a COX-2-mediated pathway for anandamide metabolism, and the metabolites formed represent a novel class of prostaglandins. 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.
