In vitro study	Lithocholic acid (LCA) is a hydrophobic secondary bile acid formed by the 7α-dehydroxylation of the bacterium chenocholic acid in the intestine. LCA causes intrahepatic cholestasis (termination or obstruction of bile flow). LCA activates PXR (pregnane X receptor), and LCA-induced severe liver injury can be protected by PXR activation. LCA is a ligand for the farnesol X receptor (FXR) with an EC50 of 3.8 μm. LCA binds directly to VDR (vitamin D receptor),K I is 29 μm, and activates VDR (vitamin D receptor),K I is 30 μm, compared with other nuclear receptors (e. G. PXR,FXR) it has a higher sensitivity, and its toxic effects are therefore suppressed. LCA has tumor-promoting activity and inhibits mammalian DNA polymerase β with an IC50 of 15 μm.
In vivo study	Binding with rodents after administration of LCA causes intrahepatic cholestasis, a pathological condition characterized by a decrease in bile flow and accumulation of bile components in the liver and blood. In a DMH (dimethylhydrazine)-induced mouse model of carcinogenesis, LCA almost completely inhibited apoptosis in the precancerous colon. LCA activates VDR, inducing in vivo expression of CYP3A, a cytochrome P450 enzyme that detoxizes LCA in the liver and intestine.

Overview	Lithocholic acid is a secondary bile acid, also known as cholic acid, 3 A- hydroxycholanic acid, lithocholic acid, 3 A- alkanic acid, lithic acid, 3-hydroxycholenic acid, lithic acid, exist in the bile of higher vertebrates. Its molecular structure contains both hydrophilic groups and hydrophobic groups, so the three-dimensional configuration of bile acids has two properties: hydrophilic and hydrophobic, so bile acids have strong interfacial activity. After consulting the literature, it is found that lithocholic acid has more pharmacological activities, such as: inhibiting tumor growth, selectively killing breast cancer cells, and selectively inhibiting the activity of mammalian DNA polymerase.
Classification	Bile acids are structurally divided into two categories: one is free bile acids, including cholic acid, Deoxycholic acid (deoxycholic acid), chenodeoxycholic acid, and lithocholic acid; the other is conjugated bile acid, it is formed by the combination of the above free bile acids with glycine or taurine, mainly including glycocholic acid, glycochenodeoxycholate acid, taurocholic acid and taurochenodeoxycholate acid.
pharmacological action	lithocholic acid can kill glioma cells and is harmless to normal nerve cells. the specific principle of action: low concentration of lithocholic acid (LCA) can make BE(2)-m17 and SK-n-MCIXC cells sensitive to hydrogen peroxide-induced cell decline, A certain concentration of LCA makes the original culture of human neuron cells have a certain ability to resist this type of cell death. LCA can kill BE(2)-m17 and SK-n-MCIXC cells not only through the path of internal decay cell death driven by triggering the permeabilization of the outer mitochondrial membrane and the activation of the initiator CASPASE-9, but also through the external path of cell decay involving the CASPASE-8 activation of the initiator. These intrinsic and extrinsic pathways of tumor cell decay can be interpreted by the apoptotic cascade.
biological activity	Lithocholic acid is a bile acid that can dissolve fat for absorption.
