NCIt definition : The diammonium salt of glycyrrhizin and the active constituent in the traditional
Chinese medicinal herb Glycyrrhiza uralensis (Chinese liquorice or Gan-Cao) with anti-inflammatory,
antioxidant and hepatoprotective properties. Diammonium glycyrrhizinate (DG) is slowly
metabolized within the cells into glycyrrhetic acid, which inhibits enzymes that control
cortisol metabolism and contributes to this agent's anti-inflammatory effect. Although
the exact mechanism of action remains to be fully elucidated, DG may prevent or reduce
hepatotoxicity via the scavenging of free radicals. This agent also upregulates the
expression of transcription coactivator PGC-1alpha and modulates hepatic enzymes such
as alanine aminotransferase (ALT), aspartate aminotransferase (AST), superoxide dismutase
and glutathion peroxidase.;
