Tauro-β-muricholic acid (TβMCA) is a trihydroxylated bile acid. Tauro-β-muricholic acid is a competitive and reversible FXR antagonist (IC50 = 40 μM). Tauro-β-muricholic acid has antiapoptotic effect. Tauro-β-muricholic acid inhibits bile acid-induced hepatocellular apoptosis by maintaining the mitochondrial membrane potential[1][2].
