PF-06409577 AMPK activator

PF-06409577 is an orally bioavailable AMPK activator with EC50 of 7 nM for α1β1γ1 in the TR-FRET assay and it shows no detectable inhibition of hERG in a patch-clamp assay (100 μM) and was not an inhibitor (IC50 > 100 μM) of the microsomal activities of major human cytochrome P450 isoforms.

In vitro

In vitro PF-06409577 activates α1β1γ1 and α2β1γ1 AMPK isoforms with EC50 of 7.0 nM and 6.8 nM but this compound was much less active against α1β2γ1/α2β2γ1/α2β2γ3 AMPK isoforms with EC50 greater 4000 nM[1].

In Vivo

In vivo PF-06409577 exhibits efficacy in a preclinical model of diabetic nephropathy[1]. 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, this compound 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 material in 0.5% methylcellulose suspension, it 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. This chemical is subject to a higher degree of first pass intestinal glucuronidation in the rat (relative to other preclinical species and human)[2].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
