SR 144528

SR 144528 is a cannabinoid 2 (CB2) receptor antagonist (Ki = 0.6 nM). It is selective for CB2 over CB1 receptors in CHO cells expressing the human receptors (Ki = 437 nM). SR 144528 reverses CP 55,940-induced inhibition of forskolin-induced adenylyl cyclase activity in CHO cells expressing human CB2 receptors (EC50 = 10 nM). SR 144528 (0.01 mg/kg) reduces paw swelling in a mouse model of carrageenan-induced paw edema.Formal Name: 5-(4-chloro-3-methylphenyl)-1-[(4-methylphenyl)methyl]-N-[(1S,2S,4R)-1,3,3-trimethylbicyclo[2.2.1]hept-2-yl]-1H-pyrazole-3-carboxamide.
