MI-883 is an orally active Constitutive Androstane Receptor (CAR, EC50=73 nM) agonist and a Pregnane X Receptor (PXR, IC50=0.1 µM) antagonist. It enhances CAR LBD assembly (EC50=0.38 µM) and activates the CAR3 variant (EC50=0.074 µM), inducing CYP2B6 mRNA expression in HepaRG and primary human hepatocytes. Additionally, MI-883 inhibits the basal activity of PXR (IC50=2.03 µM) and reduces CYP3A4 mRNA expression in transiently transfected HepG2 cells. It also regulates cholesterol metabolism and bile acid excretion, improving hypercholesterolemia in mouse models.
