Tauro-beta-muricholic Acid-d4 (sodium salt)

Tauro-beta-muricholic acid-d4 (TbetaMCA-d4) is intended for use as an internal standard for the quantification of TbetaMCA (Cay-20289) by GC- or LC-MS. TbetaMCA is a competitive and reversible antagonist of the farnesoid X receptor (FXR, IC50 = 40 µM) and a taurine-conjugated form of the murine-specific primary bile acid beta-muricholic acid (Cay-20287). TbetaMCA accumulates in germ-free mice under normal conditions but is reduced after colonization with feces from a human donor. TbetaMCA is increased in the intestines of mice resistant to high-fat diet-induced obesity, fatty liver, and diabetes.Formal Name: 2-[[(3alpha,5beta,6beta,7beta)-3,6,7-trihydroxy-24-oxocholan-24-yl-2,2,4,4-d4]amino]-ethanesulfonic acid, monosodium salt.
