• 説明

  Ursodeoxycholic acid-d₄ (UDCA-d₄) is intended for use as an internal standard for the quantification of UDCA (Item No. 15121) by GC- or LC-MS. UDCA is a secondary bile acid formed via epimerization of chenodeoxycholic acid (CDCA; ). UDCA is also a metabolite of lithocholic acid (LCA; ) in human liver microsomes. It inhibits taurocholic acid uptake in HeLa cells expressing recombinant sodium/taurocholate cotransporting polypeptide (NTCP) with an IC₅₀ value of 3.6 μM. UDCA (50 μM) inhibits apoptosis induced by deoxycholic acid (DCA; Item Nos. 20756 | 18231) or ethanol in primary rat hepatocytes. Dietary administration of UDCA blocks DCA-induced increases in the number of TUNEL-positive hepatocytes in rats. Formulations containing UDCA have been used in the treatment of primary biliary cirrhosis.

• 使用

  Ursodeoxycholic Acid-d4 is a deuterated form of Ursodeoxcholic Acid (U850000), which is used as an anticholelithogenic. Ursodeoxcholic Acid is an epimer with Chenodiol with respect to the hydroxyl group at C7. Ursodeoxycholic Acid-d4 was used as an internal standard for rapid quantification of bile acids by liquid chromatography-tandem mass spectrometry.
