Isoursodeoxycholic Acid

Isoursodeoxycholic acid is a 3beta-epimer of the secondary bile acid ursodeoxycholic acid (UDCA, Cay-15121). It is formed from UDCA via epimerization in vivo and can be isomerized back into UDCA. Isoursodeoxycholic acid (2,500 mg/kg in the diet) decreases serum alkaline phosphatase (ALP), aspartate aminotransferase (AST), and alanine transaminase (ALT) levels in bile duct-ligated rats but does not affect liver histology.Formal Name: (3beta,5beta,7beta)-3,7-dihydroxy-cholan-24-oic acid.
