Lithocholic acid (3α-Hydroxy-5β-cholanic acid), a secondary bile acid formed from chenodeoxycholate by bacterial action, acts as a detergent to solubilize fats for absorption and is itself absorbed. It is also 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. 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. 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.
ln Vitro |
Lithocholic Acid has an IC50 of 0.7 μM and 1.4 μM, respectively, to block FXR activation produced by GW4064 and CDCA [5]. In HepG2 cells, 100 nM GW4064-induced BSEP expression is inhibited by 10-30 μM lithocholic acid over a 24-hour period [5]. Lithocholic Acid (0-500 μM) suppresses neuroblastoma cell growth (BE(2)-m17, SK-n-SH, SK-n-MCIXC, and Lan-1) in a dose-dependent manner[3].

ln Vivo |
When added to the food at a rate of 0.6% for seven days, lithocholic acid raises the levels of TGFB1, TGFBR1, and TGFBR2 mRNA in the liver of male C57BL/6 mice, activates SMAD3, and causes biliary injury [4]. Male C57BL/6 mice given intraperitoneal injections of lithocholic acid (125 mg/kg, twice daily for four days) develop liver damage and have elevated levels of AST, ALT, and ALP [2].

Animal Protocol |
Animal/Disease Models: Male mice (C57BL/6)[4].
Doses: 0.6% LCA-supplement diet, with the AIN93G diet as a control Route of Administration: in diet, for 6 days Experimental Results: Induced liver injury. Activated TGFβ-SMAD3 signaling. Increased serum ALP activities. Animal/Disease Models: Male mice (C57BL/6)[2]. Doses: 125 mg/kg, dissolved in corn oil Route of Administration: ip, twice a day for four days Experimental Results: Induced liver injury, generated necrosis and neutrophilic -granulocytic infiltrate (H&E staining). Increased AST, ALT and ALP level. |

Metabolism / Metabolites
LITHOCHOLIC ACID (24)C(14) IS CONVERTED BY RAT LIVER HOMOGENATE INTO 3ALPHA-6BETA-DIHYDROXY-5BETA-CHOLANIC ACID, 7SIGMA-HYDROXYLATION OCCURS, HYDROXYLATION CONJUGATION WITH TAURINE & FORMATION OF 3-SULFATE ESTER CAN BE DEMONSTRATED. LABELED LITHOCHOLATE WAS INJECTED INTO GALLSTONE PATIENTS & HEALTHY VOLUNTEERS, MAJORITY OF RADIOACTIVITY IN BILE (50-60%) WAS PRESENT AS SULFATED CONJUGATES. DEGREE OF SULFATION WAS GREATER FOR GLYCINE THAN TAURINE CONJUGATES, WHICH SUGGESTED PREFERENTIAL SULFATION OF GLYCINE CONJUGATES. Lithocholic Acid has known human metabolites that include 6alpha-Hydroxylithocholic acid. |

Two groups of 5 to 6-wk-old hamsters (number not stated) were given 500 mg/kg BHP subcutaneously once per week for 5 weeks, and group 3 was given no further treatment; group 4 was given 0.5% LCA in feed for 30 weeks, all animals were autopsied at 35 weeks. There was no difference in food consumption or body weight between these 2 groups. There were no differences in number on liver lesions (group 3: 15/15 hyperplastic nodules, 2/15 hepatocellular carcinoma, 1/15 cholangiocarcinoma; group 4: 22/22 hyperplastic nodules, 3/22 hepatocellular carcinoma, 3/22 cholangiocarcinoma). However, there was a significant difference in the pancreatic tumors: group 3 had 4/15 gross tumors, 5/15 carcinomas, 4/15 adenomas while group 4 had 13/22 gross tumors, 15/22 carcinomas (P<.04) and 2/22 adenomas. Under the conditions of this experiment, LCA was not carcinogenic when administered alone, but was an effective promoter of BHP pancreatic carcinogenesis. |

Lithocholic acid is a monohydroxy-5beta-cholanic acid with a alpha-hydroxy substituent at position 3. It is a bile acid obtained from chenodeoxycholic acid by bacterial action. It has a role as a human metabolite, a mouse metabolite and a geroprotector. It is a bile acid, a monohydroxy-5beta-cholanic acid and a C24-steroid. It is a conjugate acid of a lithocholate. Lithocholic acid has been reported in Homo sapiens with data available. A bile acid formed from chenodeoxycholate by bacterial action, usually conjugated with glycine or taurine. It acts as a detergent to solubilize fats for absorption and is itself absorbed. It is used as cholagogue and choleretic. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
