2-Arachidonoyl glycerol (2-AG; ) has been isolated from porcine brain, and has been characterized as the natural endocannabinoid ligand for the central cannabinoid receptor. Incubation of 2-AG with cyclooxygenase-2 and specific prostaglandin H2 (PGH2) isomerases in cell cultures and isolated enzyme preparations results in PG glyceryl ester formation. The biosynthesis of PGH, PGD, PGE, PGF, and thromboxane A-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 PGF2α-1-glyceryl ester has been investigated, little is known about its intrinsic biological activity.
ChEBI: Prostaglandin F2alpha 1-glyceryl ester is a 1-monoglyceride resulting from the condensation of the carboxy group of prostaglandin F2alpha with the 1-hydroxy group of glycerol. It has a role as a human metabolite. It is a 1-monoglyceride, an olefinic compound, a secondary alcohol, a prostaglandins Falpha and a pentol. It is functionally related to a prostaglandin F2alpha.
