[CAS NO. 1467057-23-3]  PF-06409577

PF-06409577 exhibits efficacy in a preclinical model of diabetic nephropathy. It exhibits high plasma protein binding in rat (plasma unbound fraction, fu,p = 0.0044), dog (fu,p = 0.028), monkey (fu,p = 0.032), and human (fu,p = 0.017). Following iv administration, PF-06409577 demonstrates moderate plasma clearance (CLp) in rats (22.6 mL/min/kg), dogs (12.9 mL/min/kg), and monkeys (8.57 mL/min/kg) and was well distributed with steady state distribution volumes (Vdss) ranging from 0.846-3.15 L/kg. Following oral administration of crystalline PF-06409577 in 0.5% methylcellulose suspension, PF-06409577 is rapidly absorbed (Tmax = 0.25-1.20 h) in rats, dogs, and monkeys. The corresponding oral bioavailability (F) values in rats, dogs, and monkeys, were 15%, 100%, and 59%, respectively. PF-06409577 is subject to a higher degree of first pass intestinal glucuronidation in the rat (relative to other preclinical species and human).
