CP-640186 (oral gavage; 4.6-21 mg/kg; once) demonstrates acute efficacy. CP-640186 (intravenous injection and oral gavage; Intravenous dose, 5 mg/kg; oral dose, 10 mg/kg; once) shows lowe drug exposure in the rat than the ob/ob mouse at equal doses. CP-640186 (oral gavage; 100 mg/kg; once) treatment shows a complete shift from carbohydrate utilization to fatty acid utilization as a source of energy at high exposure level. Animal Model: Male ob/ob mice Dosage: 4.6-21 mg/kg Administration: Oral gavage; 4.6-21 mg/kg; once Result: Demonstrated acute efficacy for up to 8 h after oral administration, exhibiting ED50 values of 4.6, 9.7, and 21 mg/kg, at 1, 4, and 8 h, respectively, after treatment. Animal Model: Male Sprague-Dawley rats Dosage: Intravenous dose, 5 mg/kg; oral dose, 10 mg/kg Administration: Intravenous injection and oral gavage; Intravenous dose, 5 mg/kg; oral dose, 10 mg/kg; once Result: Showed a plasma half-life of 1.5 h, a bioavailability of 39%, a Clp of 65 ml/min/kg, a Vdss of 5 liters/kg, an oral Tmax of 1.0 h, an oral Cmax of 345 ng/mL, and an oral AUC0-∞ of 960 ng•h/mL. Animal Model: Male ob/ob mice Dosage: Intravenous dose, 5 mg/kg; oral dose, 10 mg/kg Administration: Intravenous injection and oral gavage; Intravenous dose, 5 mg/kg; oral dose, 10 mg/kg; once Result: Showed a plasma half-life of 1.1 h, a bioavailability of 50%, a Clp of 54 ml/min/kg, an oral Tmax of 0.25 h, an oral Cmax of 2177 ng/mL, and an oral AUC0-∞ of 3068 ng•h/mL. Animal Model: Twenty male Sprag |
