Biological Activity for SR 144528

SR 144528 is a high affinity and selective CB2 inverse agonist (Ki = 0.6 nM). Exhibits >700-fold selectivity for CB2 over CB1 receptors. Blocks the effects of CP 55,940 (Cat. No. 0949) on forskolin-sensitive adenylyl cyclase activity and MAPK in CHO cells expressing CB2 receptors. Also blocks CP 55,940-induced B-cell activation. Orally bioavailable.
