Bioassay-guided isolation and quantification of the alpha-glucosidase inhibitory compound, Glycyrrhisoflavone, from Glycyrrhiza uralensis
Nat Prod Commun 2010 Jul;5(7):1049-53.PMID:20734938doi
The EtOAc extract of the roots of Glycyrrhiza uralensis exhibited alpha-glucosidase inhibitory activity. Bioassay-guided fractionation resulted in the isolation of an active prenylflavonoid, Glycyrrhisoflavone. Its structure was elucidated by NMR and MS analyses. A simple method to prepare Glycyrrhisoflavone from the 95% EtOH extract of the roots of G. uralensis was developed by combination of Diaion HP-20 column chromatography (CC), silica gel CC, and preparative HPLC. An HPLC-PDA method was developed for quantitative determination of Glycyrrhisoflavone in the roots of G. uralensis. The sample was extracted with MeOH and analyzed using a reversed-phase column with isocratic elution with CH3CN-H2O (0.06% trifluoroacetic acid) (42:58) at a flow rate of 1.2 mL/min, a column temperature of 40 degrees C, and a detection wavelength of 260 nm. The method allowed the determination of Glycyrrhisoflavone in the concentration range of 5-500 microg/mL. The relative standard deviation values of the precision and repeatability were 0.3% and 2.0%, respectively. The limits of detection and quantification were 0.5 microg/mL and 5 microg/mL, respectively. The relative recovery rate was 100.2 +/- 1.8%. Based on the validation results, the HPLC determination method was found to be precise, accurate, and time conservative. This method was applied successfully to nine different root samples of G. uralensis. The amounts of Glycyrrhisoflavone in these samples were 15-93 mg/100 g of dried powdered plant material.
Prenylflavonoids from Glycyrrhiza uralensis and their protein tyrosine phosphatase-1B inhibitory activities
Bioorg Med Chem Lett 2010 Sep 15;20(18):5398-401.PMID:20724155DOI:10.1016/j.bmcl.2010.07.110.
Two new 2-arylbenzofurans, glycybenzofuran (1) and cyclolicocoumarone (2), together with 10 known flavonoids including licocoumarone (3), Glycyrrhisoflavone (4), glisoflavone (5), cycloglycyrrhisoflavone (6), isoliquiritigenin (7), licoflavone A (8), apigenin (9), isokaempferide (10), glycycoumarin (11), and isoglycycoumarin (12), were isolated from the roots of Glycyrrhiza uralensis and their structures were determined by extensive spectroscopic analyses. Compounds 1 and 5 showed significant protein tyrosine phosphatase-1B (PTP1B) inhibitory activity in vitro with the IC50 values of 25.5 and 27.9 microM, respectively. The structure-activity relationship indicated that the presence of prenyl group and ortho-hydroxy group is important for exhibiting the activity. Kinetic analysis indicated that compound 1 inhibits PTP1B by a competitive mode, whereas compound 5 by a mixed mode.
Identification of tyrosinase inhibitors from Glycyrrhiza uralensis
Planta Med 2005 Aug;71(8):785-7.PMID:16142649DOI:10.1055/s-2005-871232.
Tyrosinase is a key enzyme in the production of melanins. Phytochemical studies of a Glycyrrhiza uralensis extract were performed by measuring the tyrosinase and melanin synthesis inhibitory activity. Glycyrrhisoflavone and glyasperin C were identified as tyrosinase inhibitors for the first time. Glyasperin C showed a stronger tyrosinase inhibitory activity (IC (50) = 0.13 +/- 0.01 microg/mL) than glabridin (IC (50) = 0.25 +/- 0.01 microg/mL) and a moderate inhibition of melanin production (17.65 +/- 8.8 % at 5 microg/mL). Glycyrrhisoflavone showed a strong melanin synthesis inhibitory activity (63.73 +/- 6.8 % inhibition at 5 microg/mL). These results suggest that glyasperin C and Glycyrrhisoflavone could be promising candidates in the design of skin-whitening agents.
Biotransformation of the Phenolic Constituents from Licorice and Cytotoxicity Evaluation of Their Metabolites
Int J Mol Sci 2021 Sep 18;22(18):10109.PMID:34576274DOI:10.3390/ijms221810109.
Biotransformation of four bioactive phenolic constituents from licorice, namely licoisoflavanone (1), Glycyrrhisoflavone (2), echinatin (3), and isobavachalcone (4), was performed by the selected fungal strain Aspergillus niger KCCM 60332, leading to the isolation of seventeen metabolites (5-21). Structures of the isolated compounds were determined on the basis of extensive spectroscopic methods, twelve of which (5-7, 10-17 and 19) have been previously undescribed. A series of reactions including hydroxylation, hydrogenation, epoxidation, hydrolysis, reduction, cyclization, and alkylation was observed in the biotransformation process. All compounds were tested for their cytotoxic activities against three different human cancer cell lines including A375P, MCF-7, and HT-29. Compounds 1 and 12 exhibited most considerable cytotoxic activities against all the cell lines investigated, while compounds 2 and 4 were moderately cytotoxic. These findings will contribute to expanding the chemical diversity of phenolic compounds, and compounds 1 and 12 may serve as leads for the development of potential cancer chemopreventive agents.
Schottiin, a new prenylated isoflavones from Psorothamnus schottii and antibacterial synergism studies between methicillin and fremontone against methicillin-resistant Staphylococcus aureus ATCC 1708
Nat Prod Res 2022 Jun;36(12):2984-2992.PMID:34121536DOI:10.1080/14786419.2021.1937157.
Bioactivity guided isolation of an ethanol extract of the root of Psoromanthus schottii (Family Fabaceae) afforded a new prenylated isoflavone, named schottiin (5,7,5'-trihydroxy-4'-O-methyl-6'-(3,3-dimethylallyl)-isoflavone) (1), together with four other isoflavones, including fremontone (2), 5,7,4',5'-tetrahydroxy-2'-(3,3-dimethylallyl)-isoflavone (3), Glycyrrhisoflavone (4) and fremontin (5), of which 3 and 4 identified as isomeric mixture. Structures of 1-5 were determined by full spectroscopic analyses. A comprehensive 2 D NMR spectral data has allowed revising the structure of fremontone as 2 from previously reported 2 A. Compound 2 showed weak in-vitro antibacterial activity against methicillin-resistant Staphylococcus aureus (MRSA). A combination study using a checkerboard assay between fremontone (2) and methicillin exhibited a synergistic activity with 8-fold decrease in MIC of methicillin, as well as an additive effect with vancomycin against MRSA ATCC 1708. Compounds 1 and 2 also showed moderate antiplasmodial activity against chloroquine-sensitive (D6) and -resistant (W2) strains of Plasmodium falciparum with no cytotoxicity to mammalian Vero cells.
