Lithocholic acid (Synonyms: 石胆酸; 3α-Hydroxy-5β-cholanic acid)
Lithocholic acid是有毒的次级胆汁酸,能促使肝内胆汁淤积,能促进肿瘤发生。
生物活性
Lithocholic acid is a toxic secondary bile acid, causes intrahepatic cholestasis, has tumor-promoting activity. Target: Others Lithocholic acid has been used in a study to assess cholestasis and its action on several organs and tissues in rats. It has also been used in a study to investigate the regulation of hepatic phospholipid and bile acid homeostasis through SMAD3 activation by TGFβ. It has been implicated in human and experimental animal carcinogenesis. Preliminary in vitro research suggests that LCA selectively kills neuroblastoma
