Glycyrrhizic acid inhibits monoamine oxidase (MAO) with the IC50 value of 0.16 μM^[1]. With midazolam as the probe substrate, GA greatly decreased CYP3A4 activity with IC50 values of 8.195 μM in HLMs and 7.498 μM in the recombinant cDNA-expressed CYP3A4 enzyme system, respectively. GA could also inhibit the activity of CYP3A4 competitively, with a Ki value of 1.57 μM in HLMs. CYP2C9 and CYP2C19 could also be inhibited strongly by GA with IC50 of 42.89 and 40.26 μM in HLMs, respectively^[2].

Glycyrrhizic acid is a triterpenoid saponinl which acts as a direct HMGB1 (high mobility group box 1) antagonist that inhibits HMGB1-dependent inflammatory molecule expression and oxidative stress. It can also inhibit 11 beta-hydroxysteroid dehydrogenase and monoamine oxidase (MAO).

The inhibitory of glycyrrhizic acid to monoamine oxidase (MAO) was relatively not strong, yet it cannot be ignored because of its abundant presence in most species of licorice^[1]. Glycyrrhizic acid also promotes GLP-1 secretion with a marked elevation of calcium levels in intestinal NCI-H716 cells that secrete GLP-1. Glycyrrhizic acid can enhance GLP-1 secretion through TGR5 activation^[3].

Glycyrrhizic acid competitively inhibits 11 beta-hydroxysteroid dehydrogenase (11 beta-HSD) type 2 (11-HSD2) enzymatic activity. 11-HSD2 protein and mRNA levels were decreased in rats given 120 mg/kg of glycyrrhizic acid twice a day for 2 weeks^[4]. Plasma HMGB1 level was significantly decreased compared with that observed in the NS group when rats were pre-treated with 4mg/kg glycyrrhizic acid^[5].
