General description

18α-Glycyrrhetinic acid (18α-GA) is a bioactive triterpenoid found in licorice. It shows selective inhibition of 11-HSD1 (11-hydroxysteroid dehydrogenase 1). It also shows anti-proliferative and apoptotic effect on hepatic stellate cells (HSCs).


18α-Glycyrrhetinic acid may be used to synthesize:
  • 3-keto-18α-glycyrrhetinic acid
  • methyl esters of 18α-glycyrrhetinic acid
  • methyl esters of 3-keto-18α-glycyrrhetinic acid
