Background:
Lithocholic acid (LCA) is a toxic secondary bile acid, causing intrahepatic cholestasis, which has tumor-promoting activity.
In vitro: Among 17 kinds of bile acids with respect to inhibition of mammalian DNA polymerases, only LCA and its derivatives inhibited DNA polymerases, while other bile acids did not show inhibitory effect [1].
In vivo: Administration of LCA and its conjugates to rodents causes intrahepatic cholestasis, which is a pathogenic state characterized by decreased bile flow and the accumulation of bile constituents in the liver and blood [2].
Clinical trials: Currently no clinical data are available.
