MI-883 is the orally active agonist for Constitutive Androstane Receptor (CAR, EC50=73 nM) and the antagonist for Pregnane X Receptor (PXR, IC50=0.1 μM). MI-883 stimulates CAR LBD assembly (EC50=0.38 µM) and CAR3 variant activation (EC50=0.074 µM), induces CYP2B6 mRNA expression in HepaRG and primary human hepatocytes. MI-883 inhibits basal PXR activity IC50=2.03 µM) in transiently transfected HepG2 cells, blocks CYP3A4 mRNA expression in HepG2. MI-883 regulates cholesterol metabolism and bile acid excretion, improves hypercholesterolemia in mouse models.
