Glycyrin, one of the main PPAR-gamma ligands of licorice, can significantly decrease the blood glucose levels of genetically diabetic KK-A(y) mice. Glycyrin exhibits anti-BsFtsZ GTPase activities, at levels comparable to that of the synthetic FtsZ inhibitor, Zantrin Z3. Glycyrin has anti-hepatitis C virus (HCV) activity with the IC(50) value of 7.2 ug/mL; it shows antibacterial activity against upper airway respiratory tract bacteria such as Streptococcus pyogenes, Haemophilus influenzae and Moraxella catarrhalis; it also possesses weaker anti-Helicobacter pylori activity, it may be a useful chemopreventive agent for peptic ulcer or gastric cancer in H. pylori-infected individuals.

    Anti-hepatitis C virus compounds obtained from Glycyrrhiza uralensis and other Glycyrrhiza species.[Pubmed: 24397541 ]
    Development of complementary and/or alternative drugs for treatment of hepatitis C virus (HCV) infection is still much needed from clinical and economic points of view. Antiviral substances obtained from medicinal plants are potentially good targets to study. Glycyrrhiza uralensis and G. glabra have been commonly used in both traditional and modern medicine.
    METHODS AND RESULTS:
    In this study, extracts of G. uralensis roots and their components were examined for anti-HCV activity using an HCV cell culture system. It was found that a methanol extract of G. uralensis roots and its chloroform fraction possess anti-HCV activity with 50%-inhibitory concentrations (IC(50)) of 20.0 and 8.0 μg/mL, respectively. Through bioactivity-guided purification and structural analysis, glycycoumarin, Glycyrin, glycyrol and liquiritigenin were isolated and identified as anti-HCV compounds, their IC(50) being 8.8, 7.2, 4.6 and 16.4 μg/mL, respectively. However, glycyrrhizin, the major constituent of G. uralensis, and its monoammonium salt, showed only marginal anti-HCV activity. It was also found that licochalcone A and glabridin, known to be exclusive constituents of G. inflata and G. glabra, respectively, did have anti-HCV activity, their IC(50) being 2.5 and 6.2 μg/mL, respectively. Another chalcone, isoliquiritigenin, also showed anti-HCV activity, with an IC(50) of 3.7 μg/mL. Time-of-addition analysis revealed that all Glycyrrhiza-derived anti-HCV compounds tested in this study act at the post-entry step.
    CONCLUSIONS:
    In conclusion, the present results suggest that glycycoumarin, Glycyrin, glycyrol and liquiritigenin isolated from G. uralensis, as well as isoliquiritigenin, licochalcone A and glabridin, would be good candidates for seed compounds to develop antivirals against HCV.

    Anti-Helicobacter pylori flavonoids from licorice extract.[Pubmed: 12127165]
    Licorice is the most used crude drug in Kampo medicines (traditional Chinese medicines modified in Japan).
    METHODS AND RESULTS:
    The extract of the medicinal plant is also used as the basis of anti-ulcer medicines for treatment of peptic ulcer. Among the chemical constituents of the plant, glabridin and glabrene (components of Glycyrrhiza glabra), licochalcone A (G. inflata), licoricidin and licoisoflavone B (G. uralensis) exhibited inhibitory activity against the growth of Helicobacter pylori in vitro. These flavonoids also showed anti-H. pylori activity against a clarithromycin (CLAR) and amoxicillin (AMOX)-resistant strain. We also investigated the methanol extract of G. uralensis. From the extract, three new isoflavonoids (3-arylcoumarin, pterocarpan, and isoflavan) with a pyran ring, gancaonols A[bond]C, were isolated together with 15 known flavonoids. Among these compounds, vestitol, licoricone, 1-methoxyphaseollidin and gancaonol C exhibited anti-H. pylori activity against the CLAR and AMOX-resistant strain as well as four CLAR (AMOX)-sensitive strains. Glycyrin, formononetin, isolicoflavonol, glyasperin D, 6,8-diprenylorobol, gancaonin I, dihydrolicoisoflavone A, and gancaonol B possessed weaker anti-H. pylori activity.
    CONCLUSIONS:
    These compounds may be useful chemopreventive agents for peptic ulcer or gastric cancer in H. pylori-infected individuals.

    Antibacterial compounds of licorice against upper airway respiratory tract pathogens.[Pubmed: 11575586]
    The antibacterial activity of compounds obtained from licorice was measured against upper airway respiratory tract bacteria such as Streptococcus pyogenes, Haemophilus influenzae and Moraxella catarrhalis.
    METHODS AND RESULTS:
    Among the tested compounds, licoricidin exhibited the highest activity against all tested microorganisms with an MIC of 12.5 microg/mL. Three coumarin derivatives, glycyrol, Glycyrin and glycycoumarin also showed antibacterial activity.

    Filamenting temperature-sensitive mutant Z inhibitors from Glycyrrhiza glabra and their inhibitory mode of action.[Pubmed: 28196701]
    FtsZ is an essential protein for bacterial cell division, and an attractive and underexploited novel antibacterial target protein.
    METHODS AND RESULTS:
    Screening of Indonesian plants revealed the inhibitory activity of the methanol extract of Glycyrrhiza glabra on the Bacillus subtilis FtsZ (BsFtsZ) GTPase, and further bioassay-guided fractionation of the active methanol extract led to the isolation of seven known polyketides (1-7). Among them, gancaonin I (1), Glycyrin (3), and isolicoflavanol (5) exhibited anti-BsFtsZ GTPase activities, at levels comparable to that of the synthetic FtsZ inhibitor, Zantrin Z3. Enzymatic assays using a BsFtsZ Val307R mutant protein and in silico simulations suggested that 1, 3, and 5 bind to the cleft on BsFtsZ, as in the case of the previously reported uncompetitive FtsZ inhibitor, PC190723, and thereby display their significant anti-BsFtsZ inhibitory activities. Furthermore, 1 also showed significant inhibitory activity against B. subtilis, with a MIC value of 5μM.
    CONCLUSIONS:
    The present study provides new insights into the naturally occurring B. subtilis growth inhibitors.

    Phenolics with PPAR-gamma ligand-binding activity obtained from licorice (Glycyrrhiza uralensis roots) and ameliorative effects of glycyrin on genetically diabetic KK-A(y) mice.[Pubmed: 14643306]
    The EtOAc extract of licorice (Glycyrrhiza uralensis roots) exhibited considerable PPAR-gamma ligand-binding activity.
    METHODS AND RESULTS:
    Bioassay-guided fractionation of the extract using a GAL-4-PPAR-gamma chimera assay method resulted in the isolation of two isoflavenes, one of which is a new compound named dehydroglyasperin D, an isoflavan, two 3-arylcoumarins, and an isoflavanone as the PPAR-gamma ligand-binding active ingredients of licorice. The isoprenyl group at C-6 and the C-2' hydroxyl group in the aromatic ring-C part in the isoflavan, isoflavene, or arylcoumarin skeleton were found to be the structural requirements for PPAR-gamma ligand-binding activity.
    CONCLUSIONS:
    Glycyrin, one of the main PPAR-gamma ligands of licorice, significantly decreased the blood glucose levels of genetically diabetic KK-A(y) mice.
