N-Arachidonylglycine (NA-Gly), a carboxylic analog of the endocannabinoid anandamide (AEA), is a GPR18 agonist (EC50 = 44.5 nM). Unlike AEA, N-Arachidonylglycine has no activity at either CB1 or CB2 receptors. N-Arachidonylglycine inhibits GLYT2 (IC50 = 5.1 μM). N-Arachidonylglycine also is an effective activator of endometrial cell migration.
