24-Norursodeoxycholic acid

SKU: orb1219307

Description

24-norursodeoxycholic acid is a side chain-shortened C23 homolog of UDCA.It has shown potent anti-inflammatory, anti-cholestatic, and anti-fibrotic properties.It is a Ursodeoxycholic Acid derivative. It is superior to Ursodeoxycholic acid in the treatment of sclerosing cholangitis in Mdr2 (Abcb4) knockout mice24-norUrsodeoxycholic acid markedly improved liver tests and liver histology and significantly reduced hydroxyproline content and the number of infiltrating neutrophils and proliferating hepatocytes and cholangiocytes. 24-norUrsodeoxycholic acid underwent extensive phase I/II metabolism (hydroxylation, sulfation, and glucuronidation), thereby increasing the hydrophilicity of biliary bile acid secretion. There was a coordinated induction of bile acid detoxifying enzymes (Cyp2b10, Cyp3a11, and Sult2a1) and efflux pumps (Mrp3 and Mrp4). Ursodeoxycholic acid, in contrast, increased alanine transaminase and alkaline phosphatase levels, had no significant effects on hydroxyproline content, and induced biliary transporters and detoxification enzymes to a much smaller extent than 24-norUrsodeoxycholic acid.

Bioactivity

−

In Vitro

24-norursodeoxycholic acid (Norucholic acid) is a side chain-shortened C23 homologue of UDCA and is previously shown to be highly effective in preclinical mouse models of cholestatic and fibrotic liver diseases. 24-norursodeoxycholic acid significantly reduces serum alkaline phosphatase (ALP) levels in a dose-dependent fashion. 24-norursodeoxycholic acid also significantly reduces γ-GT, ALT, and AST serum levels.
