Research Abstract |
We demonstrated that N-acetylcysteine conjugate of ursodeoxycholic acid (UDCA-NAC) was hydrolyzed and circulated in body as UDCA after administration by injection via jugular vein, while UDCA-NAC converted to NAC-sulfate di-conjugate by rat liver cytosolic fraction. Furthermore, UDCA-NAC was shown to inhibit the increase of liver disease marker enzymes, AST and ALT, in serum of acetaminophen-induced liver injury rats. These results showed that UDCA-NAC is useful as a prodrug of the new liver, bile, digestive function improving agent.
