Glycoursodeoxycholic acid-d4 (GUDCA-d4) is intended for use as an internal standard for the quantification of GUDCA by GC- or LC-MS. GUDCA is a glycine-conjugated form of the secondary bile acid ursodeoxycholic acid .1,2 It has antioxidant effects in vitro in Barrett's esophagus cells and primary cultured rat neurons.3,4 GUDCA reduces the levels of inflammatory cytokines and prevents cell death induced by unconjugated bilirubin in an astroglial cell model of neonatal hyperbilirubinemia.5 Oral administration of GUDCA (500 mg/kg per day) decreases the severity of symptoms and increases the amount of A. muciniphila, a commensal bacterial species commonly decreased in patients with inflammatory bowel disease (IBD), in a mouse model of colitis.2
