胆汁酸之一。不是由胆甾醇在肝中直接生物合成的,而是由鹅脱氧胆酸在肠内通过细菌代谢产生的物质。在肠内生成的这种物质大部分与粪便一起排出,极少一部分被吸收,在肝中发生结合反应,以牛磺石胆酸(taurolithocholic acid)或甘氨石胆酸(glyclithocholic acid)形态出现于胆汁中。比其它胆汁酸毒性强,大量饲实验动物能引起肝胆道系统的种种障害。
Information
Lithocholic acid Lithocholic acid is a toxic secondary bile acid, causes intrahepatic cholestasis, has tumor-promoting activity, its toxic effect can be protected after it activates the vitamin D receptor , PXR and FXR .
In vitro
Lithocholic acid (LCA) is a hydrophobic secondary bile acid that is primarily formed in the intestine by the bacterial 7α-dehydroxylation of chenodeoxycholic acid. LCA causes intrahepatic cholestasis (cessation or impairment of bile flow). LCA activates PXR (pregnane X receptor), and the LCA-induced severe liver damage can be protected by the activation of PXR. LCA is a ligand for farnesoid X receptor (FXR) with EC50 of 3.8 μM. LCA directly binds VDR (vitamin D receptor) with Ki of 29μM, activates VDR (vitamin D receptor) 30 μM, with much more sensitivity than the other nuclear receptors (eg. PXR, FXR), and its toxic effect is thus protected. LCA has tumor-promoting activity, inhibits mammalian DNA Polymerase β with IC50 of 15 μM.
In vivo
Administration of LCA and its conjugates to rodents causes intrahepatic cholestasis,a pathogenic state characterized by decreased bile flow and the accumulation of bile constituents in the liver and blood. In DMH (dimethyldydrazine)-induced murine carcinogenesis model, LCA suppresses apoptosis almost completely in premalignant colon. LCA activates VDR, induces expression in vivo of CYP3A, a cytochrome P450 enzyme that detoxifies LCA in the liver and intestine.
