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.

The key feature of drug addiction is the inability to stop using a drug despite clear evidence of harm. This poster describes the brain circuits associated with addiction, and provides an overview of the main classes of addictive drugs and the neurotransmitter systems that they target.
Schizophrenia is a debilitating psychiatric disorder that affects 1% of the worldwide population. This poster describes the neurobiology of Schizophrenia, as well as highlighting the genetic and environmental factors that play a fundamental role in the etiology of the disease. The current and emerging drug targets are also discussed.
