Tauro-β-muricholic acid-d₄ sodium 

Tauro-β-muricholic acid-d₄ (sodium) is the deuterium labeled Tauro-β-muricholic acid sodium. Tauro-β-muricholic Acid sodium (T-βMCA sodium), a endogenous metabolite, is a competitive and reversible farnesoid X receptor (FXR) antagonist, with an IC50 of 40 μM[1][2][3].

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
