Prostaglandin PGE2 glyceryl ester
IUPAC 名称
1,3-dihydroxypropan-2-yl (5Z)-7-[(1S,2S,3S)-3-hydroxy-2-[(1E,3S)-3-hydroxyoct-1-en-1-yl]-5-oxocyclopentyl]hept-5-enoate
描述
GE2 glycerol ester is a COX-2 oxidative metabolite of 2-arachidonoyl glycerol, modulates inhibitory synaptic transmission in mouse hippocampal neurons
2-Arachidonoyl glycerol (2-AG) has been isolated from porcine brain,1 and has been characterized as the natural endocannabinoid ligand for the CB1 receptor.2 Incubation of 2-AG with COX-2 and specific prostaglandin H2 (PGH2) isomerases in cell cultures and isolated enzyme preparations results in prostaglandin glycerol ester formation.3 The biosynthesis of PGH, PGD, PGE, PGF, and TXA-2-glyceryl ester compounds have all been documented. The 2-glyceryl ester moiety equilibrates rapidly (within minutes) with the more stable 1-glyceryl ester, producing a 10:90 2:1-glyceryl ester mixture in typical aqueous media. While the stability and metabolism of these prostaglandin products has been investigated,4 little is known about their intrinsic biological 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. [HMDB]
