Background:
Taurolithocholic acid-d5(TLCA-d5) is intended for use as an internal standard for the quantification of TLCA by GC- or LC-MS. TLCA is a taurine-conjugated form of the secondary bile acid lithocholic acid .1TLCA (75 μM) increases caspase-3 and -7 activity in Hep3B cells transfected with sodium taurocholate cotransporting peptide (NTCP), but not nontransfected Hep3B cells.2It has been used to induce cholestasis inex vivoandin vivoanimal models of hepatocellular cholestasis.3,4Serum levels of TLCA increase approximately 5-fold in within two hours during an oral lipid tolerance test in humans.1
