MK-3903 activates 10 of the 12 pAMPK complexes with EC50 values in the range of 8-40 nM and maximal activation >50%. The compound partially activates pAMPK5 (36% max), which is only a minor component of human and mouse liver, and it does not activate pAMPK6, which is not detected in liver. MK-3903 is a weak reversible inhibitor of CYP3A4 and 2D6 in human liver microsomes (apparent IC50 > 50 μM) and does not exhibit time-dependent inhibition of CYP3A4 activity. MK-3903 is not a potent PXR agonist[1].
In Vivo
In vivo

The pharmacokinetics of MK-3903 in C57BL/6 mice, Sprague–Dawley rats, and beagle dogs were characterized by moderate systemic plasma clearance (5.0–13 mL/min/kg), a volume of distribution at steady state of 0.6–1.1 L/kg, and a terminal half-life of ∼2 h. It has low oral bioavailability (8.4%) in C57BL/6 mice, but the oral exposure is later improved using other vehicles. Oral bioavailabilities in rats and dogs are improved (27-78%). Chronic oral administration of compound MK-3903 robustly increased ACC phosphorylation in liver with more modest effects in skeletal muscle. Treatment of various mouse models with MK-3903 results in expected alterations in lipid metabolism and improvements in a measure of insulin sensitization[1].

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.
