Biological Activity

CP671305 is a potent and selective, orally active inhibitor of phosphodiesterase-4-D with high activities. CP-671305 displays high affinity (Km=12 μM) for rat hepatic Oatp1a4. CP-671305 demonstrates generally favourable pharmacokinetic properties, systemic plasma clearance after intravenous administration is low in Sprague-Dawley rats (9.60 ± 1.16 mL/min/kg), beagle dogs (2.90 ± 0.81 mL/min/kg) and cynomolgus monkeys (2.94 ± 0.87 mL/min/kg) resulting in plasma half-lives > 5 h. Moderate to high bioavailability in rats (43-80%), dogs (45%) and monkeys (26%) is observed after oral dosing.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
