Description
Putative CB1 antagonist; displays mixed activity at CB receptors
Product Description
O-2050 is an originally 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.Licensing Information
