Glycochenodeoxycholic Acid (sodium salt hydrate) (Synonyms: GCDCA, NSC 681056)

Glycochenodeoxycholic acid (GCDCA) is a glycine-conjugated form of the primary bile acid chenodeoxycholic acid .¹ It reduces formation of cholic acid in primary human hepatocytes when used at a concentration of 100 µM.² GCDCA (50, 75, and 100 µM) reduces the number LC3 puncta, a marker of autophagy, and is cytotoxic to L-02 hepatocytes.¹ GCDCA (50 µM) induces apoptosis in isolated rat hepatocytes, an effect that can be blocked by the protein kinase C (PKC) inhibitor chelerythrine .³ Fecal levels of GCDCA are decreased in a rat model of high-fat diet-induced obesity compared with rats fed a normal diet.⁴
