Tauro-ω-muricholic acid sodium (TωMCA sodium) is a bile acid released by the liver and an analog of tauro-α-muricholic acid. Tauro-ω-muricholic acid sodium is investigated as a potential marker in plasma for early-onset neonatal sepsis (EOS) and cholestasis studies[1][2]
Tauro-α-muricholic acid (T-α-MCA) sodium is a FXR (Farnesoid X receptor) antagonist (IC50=28μM). Tauro-α-muricholic acid sodium is also a endogenous metabolite that can be found in cecal[1][2].
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].
