Chemical Name: (6aR,10aR)-1-Hydroxy-3-(1-Methanesulfonylamino-4-hexyn-6-yl)-6a,7,10,10a-tetrahydro-6,6,9-trimethyl-6H-dibenzo[b,d]pyran
Biological ActivityOriginally defined as a high affinity cannabinoid CB1 receptor silent antagonist. Acts as a partial agonist in inhibiting forksolin-induced cyclic AMP stimulation (EC50 = 40.4 nM). Decreases food intake and stimulates locomotor activity in rodents. Antagonizes effects of CP55,940 (Cat. No. 0949) in vitro.
