Glycoursodeoxycholic Acid-d4 MaxSpec(R) Standard

Glycoursodeoxycholic acid-d4 (GUDCA-d4) is intended for use as an internal standard for the quantification of GUDCA (Cay-21698) by GC- or LC-MS. GUDCA is a glycine-conjugated form of the secondary bile acid ursodeoxycholic acid (UDCA, Cay-15121). It has antioxidant effects in vitro in Barrett's esophagus cells and primary cultured rat neurons. GUDCA reduces the levels of inflammatory cytokines and prevents cell death induced by unconjugated bilirubin (Cay-17161) in an astroglial cell model of neonatal hyperbilirubinemia. 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.Formal Name: N-[(3alpha,5beta,7beta)-3,7-dihydroxy-24-oxocholan-24-yl-2,2,4,4-d4]-glycine.
