primary hypercholesterolemia

MI-883 is orally active constitutive androstane receptor (CAR) (EC₅₀ of 73 nM) agonist and pregnane X Receptor (PXR) (IC₅₀ of 100 nM) antagonist. MI-883 binds to CAR and PXR ligand-binding domains, promotes CAR LBD assembly, activates CAR3 variant, stimulates CAR cytoplasmic-nuclear translocation, upregulates CAR target genes, recruits coactivators NCOA1, NCOA2, NCOA3, inhibits basal and agonist-induced PXR activation, downregulates PXR target genes, disrupts PXR-NCOR2 interaction, blocks agonist-mediated PXR-NCOA1 recruitment. MI-883 reduces plasma total cholesterol, LDL cholesterol, and hepatic free cholesterol levels, increases fecal bile acid excretion, regulates genes involved in xenobiotic metabolism, cholesterol homeostasis, and bile acid homeostasis. MI-883 exhibits metabolic stability, liver-predominant distribution, a safety profile with no observed toxicity, and does not stimulate human hepatocyte hypertrophy or hyperplasia. MI-883 can be used for the research of diet-induced hypercholesterolemia .
