tauro-a-muricholic acid

Tauro-β-muricholic acid (TβMCA) 为一种具有三羟基结构的胆汁酸，是FXR的竞争性、可逆拮抗剂，IC50值为40 μM。此外，Tauro-β-muricholic acid 能够通过维持线粒体膜电位来阻抑胆汁酸引起的肝细胞凋亡，发挥抗凋亡功能。

α-Muricholic acid is the most abundant primary bile acid in rodents.

ω-Muricholic acid (ω-MCA) is a murine-specific secondary bile acid.

β-Muricholic acid (β-MCA) is a murine-specific primary bile acid.[1],[2] Dietary administration of β-MCA reduces HMG-CoA reductase activity in liver microsomes from mice fed a high cholesterol and cholic acid diet.[3] Dietary administration of β-MCA also dissolves 100% of gallstones in a gallstone-susceptible mouse model of diet-induced cholesterol gallstones.[4]

Tauro-Obeticholic acid 是一种牛磺酸的特性代谢物。Obeticholic Acid 是口服具有活性的法尼样 X 受体激动剂。
