Notes: Chenodeoxycholic acid-d4 (CDCA-d4) is intended for use as an internal standard for the quantification of CDCA (Item No. 10011286) by GC- or LC-MS. CDCA is a hydrophobic primary bile acid.{59331} It is formed from cholesterol in the liver via a multistep process catalyzed by the cytochrome P450 (CYP) isoforms CYP7A1, CYP8B1, and CYP27A1. CDCA is a farnesoid X receptor (FXR) agonist that binds to FXRs in a TR-FRET assay (EC50 = 13 µM) and induces FXR transactivation in a reporter assay.{13291,9823} It induces transcription of the gene encoding the Nrf2 target glutamate cysteine ligase (GCL) in primary hepatocytes and HepG2 cells when used at concentrations ranging from 25 to 100 µM.{16793}
