Notes: SR 144528-d3 is intended for use as an internal standard for the quantification of SR 144528 (Item No. 9000491) by GC- or LC-MS. SR 144528 is a cannabinoid 2 (CB2) receptor antagonist (Ki = 0.6 nM).{7912} It is selective for CB2 over CB1 receptors in CHO cells expressing the human receptors (Ki = 437 nM).{17199} 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.{14732}
