Biological Activity
r-palmitoyl-(1-methyl) ethanolamide, a synthetic analog of palmitoyl ethanolamide (pea), incorporates the (r)-methyl group vicinal to the alcohol on the ethanolamine moiety. the analogous modification to arachidonoyl ethanolamide (aea) protects the molecule from hydrolysis by fatty acid amide hydrolase, prolongs duration of action and enhances potency in vivo [1].pea is an endogenous cannabinoid existed in mammalian tissues, such as liver and brain. pea has also been isolated from egg yolk [2, 3]. pea is a compound with documented anti-nociceptive and anti-inflammatory effects. during inflammation, pea is accumulated and exihibits anti-inflammatory effects, including beneficial effects in clinically relevant animal models of inflammatory pain [4].
