Biochem/physiol Actions URB602 is an inhibitor of monoacylglycerol lipase (MGL). The IC50 = 28 μM and Km = 20 μM. URB602 increases 2-arachidonoylglycerol (2-AG) concentrations. When URB602 is injected into the periaqueductal grey matter, it enhances stress-induced analgesia (tail-flick test) in a CB1-dependent manner. An effect that is prevented by a CB1 cannabinoid receptor antagonist, Rimonabant (SR141716). URB602 is not suitable for systemic administration due to relatively low potency, but useful for research of pain and stress-related disorders, which identifies MGL as a previously unrecognized therapeutic target (highlighted in Chemical Engineering News, June 27, 2005). |
