CP-945598 HCl inhibits CB1 receptor with moderate unbound microsomal clearance, low hERG affinity, and adequate CNS penetration. CP-945598 HCl has low affinity with Ki of 7.6 μM for human CB2 receptors.

CP-945598 HCl reverses four cannabinoid agonistmediated behaviors (locomotor activity, hypothermia, analgesia, and catalepsy) following administration of the synthetic CB1 receptor agonist CP-55940. CP-945598 HCl exhibits dose-dependent anorectic activity in a model of acute food intake in rodents and increased energy expenditure and fat oxidation. CP-945598 also acutely stimulates energy expenditure in rats and decreases the respiratory quotient indicating a metabolic switch to increased fat oxidation. CP-945598 at 10 mg/kg promotes a 9%, vehicle adjusted weight loss in a 10 day weight loss study in diet-induced obese mice.
