Notes: Prostaglandin D2 ethanolamide (PGD2-EA)-d4 contains four deuterium atoms. It is intended for use as an internal standard for the quantification of PGD2-EA by GC- or LC-mass spectrometry. PGD2-EA is a bioactive lipid produced by the sequential metabolism of anandamide (arachidonoyl ethanolamide) by cyclooxygenase (COX) enzymes, in particular by COX-2, and PGD synthase.{11045,22752,22753} The biosynthesis of PGD2-EA from anandamide can also be increased when anandamide metabolism is diminished by deletion of fatty acid amide hydrolase.{12142} PGD2-EA is inactive against recombinant prostanoid receptors, including the D prostanoid receptor.{12144} It increases the frequency of miniature inhibitory postsynaptic currents in primary cultured hippocampal neurons, an effect which is the opposite of that induced by anandamide.{22753}. PGD2-EA also induces apoptosis in colorectal carcinoma cell lines.{22752}
