Cayman MK-3903

MK-3903 is an activator of AMP-activated protein kinase (AMPK; EC₅₀ = 9 nM).¹ It is selective for AMPK over a kinase panel at 10 µM, as well as the cytochrome P450 (CYP) isoforms CYP3A4 and CYP2D6 (IC₅₀s = >50 µM for both) and the pregnane X receptor (PXR; EC₅₀ = >30 µM). MK-3903 (30 mg/kg) increases muscle and liver levels of phosphorylated ACC, an AMPK substrate, and reduces insulin resistance in diet-induced obese (DIO) mice. It inhibits hepatic fatty acid synthesis in db/db mice when administered at doses ranging from 3 to 30 mg/kg.
