Biological Activity for Palmitoylethanolamide

Palmitoylethanolamide is an endogenous lipid that acts as a selective GPR55 agonist (EC50 values are 4, 19 800 and > 30 000 nM at GPR55, CB2 and CB1 receptors respectively). Substrate for fatty acid amide hydrolase (FAAH) and PEA-preferring acid amidase (PAA) and exhibits antinociceptive and anticonvulsant in vivo. Directly activates PPARα (EC50 = 3 μM) producing robust anti-inflammatory actions.
