Betulonic acid (Standard) is a reference standard for research and analysis in studies involving Betulonic acid. 1. Betulonic acid (Liquidambaric acid) amide stimulated the regenerative response in hepatocytes under conditions of combined toxic exposure and promoted recovery of their qualitative and quantitative characteristics, which was accompanied by a significant decrease in the severity of liver fibrosis and the absence of cirrhotic transformation of the liver. 2. Betulonic acid derivatives have a promising cytostatic activity in vitro and could be used as potential leads for the development of new type of anti-cancer agents. 3. Betulonic acid has antiholestatic effects in mice.
