Biochem/physiol Actions

CP-945,598 is a potent, selective, high affinity and competitive cannabinoid type 1 (CB1) receptor antagonist. CP-945,598 inhibits both basal and cannabinoid agonist-mediated CB1 receptor signaling in vitro and in vivo. CP-945,598 exhibits anorectic activity in two models of acute food intake in rodents, fast-induced re-feeding and spontaneous, nocturnal feeding.
CP-945,598 is also known as 1-(8-(2-Chlorophenyl)-9-(4-chlorophenyl)-9H-purin-6-yl)-4-(ethylamino)piperidine-4-carboxamide. This orally active antagonist of the cannabinoid CB-1 receptor may be used in the treatment of obesity.

The experience of rewarding or aversive stimuli is encoded by distinct afferents to dopamine (DA) neurons of the ventral tegmental area (VTA). Several neuromodulatory systems including oxytocin regulate DA neuron excitability and synaptic transmission that process socially meaningful stimuli. We
