Chemical Name: N-(Piperidin-1-yl)-5-(4-chlorophenyl)-1-(2,4-dichlorophenyl)-4-methyl-1H-pyrazole-3-carboxamide hydrochloride
Biological ActivityPotent and selective cannabinoid CB1 receptor antagonist (Ki = 1.98 nM). Also acts as an inverse agonist reversing adenylyl cyclase inhibition by WIN 55,212-2 (Cat.No. 1038) (IC50 = 48 nM). Displays no activity at CB2 receptors. Reduces food intake and body weight in orally dosed non-obese Wistar rats. Also μ-opioid receptor antagonist (Ki = 652 nm)
