In vivo study | After CP-55940 treatment with synthetic CB1 receptor agonists, the CP-945598 of HCl reverses four cannabinoid agonist-mediated behaviors (spontaneous activity, hypothermia, analgesia, and general rigidity). CP-945598 HCl treated rodent models of acute food intake with loss of appetite and increased energy expenditure and fat oxidation. CP-945598 treatment of rats, severe stimulation of energy expenditure, and decreased the respiratory quotient, indicating metabolic conversion to increased fat oxidation. CP-945598 treated diet-induced obese mice at a dose of 10 mg/kg, CP-945598 promoted 9% weight loss in a 10-day weight loss study. |
