| 英文描述 |
Information MK-3903 MK-3903 is a potent and selective AMPK activator with an EC50 of 8 nM for α1 β1 γ1 subunit. It activates 10 of the 12 pAMPK complexes with EC50 values in the range of 8-40 nM and maximal activation >50%. Targets AMPK 8 nM(EC50) In vitro 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. 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. |
