Lithocholic acid (Synonyms: 石膽酸; 3α-Hydroxy-5β-cholanic acid)
Lithocholic acid是有毒的次級(jí)膽汁酸,能促使肝內(nèi)膽汁淤積,能促進(jìn)腫瘤發(fā)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
