Cell suspension cultures of Sophora flavescens produced large amounts of sophoraflavanone G, an 8-lavandulylated flavanone and lupalbigenin, a 6,3'-di-dimethylallylated isoflavone, by the simultaneous addition of cork tissues and methyl jasmonate. The labeling pattern of the isoprene units resulting
In this study, the antibacterial properties of sophoraflavanone G isolated from the methanol extract of Sophora flavescens were tested against 16 strains of mutans streptococci to screen and determine the optimal concentration of anti-caries natural extract. The antimicrobial activity was evaluated
In this study, sophoraflavanone G obtained from Sophora flavescens was evaluated against 10 clinical isolates of methicillin-resistant Staphylococcus aureus (MRSA), either alone or in combination with ampicillin or oxacillin, via checkerboard assay. At the end point of an optically clear well, the
It has previously been demonstrated that the addition of cork tissue to cell suspension cultures of Sophora flavescens stimulates the production of sophoraflavanone G, most of which has been recovered from the added cork tissue. In the present study, it was found that two precursors of
Sophoraflavanone G (SG), a prenylated flavonoid from Sophora alopecuroides, has been reported to have many pharmacological activities including anti-inflammation. However, the molecular mechanisms of its anti-inflammatory activity remain largely unclear. In this study we investigated the effects and
This study investigated the antibacterial activities of sophoraflavanone G from Sophora flavescens in combination with two antimicrobial agents against oral bacteria. The combined effect of sophoraflavanone G and the antimicrobial agents was evaluated using the checkerboard method to obtain a
Sophoraflavanone G (SG; 5,7,D, 2',4'-tetrahydroxy-8-lavandulylflavanone) has been isolated from Sophora flavescens and found to be effective against bacteria and to decrease cyclooxygenase (COX)-2 expression in RAW 264.7 macrophage. However, the anti-inflammatory mechanisms of SG are not well
Our study aimed at investigating the metabolic characteristics of sophoraflavanone G (SFG), one of the hepatotoxic constituents of Sophora flavescens, in rat liver microsomes (RLMs). SFG was metabolized to 3 phase I metabolites, di-hydroxylated SFG (M1), mono-hydroxylated SFG (M2), dehydrogenated
In this study the enhancement effect of Sophora pachycarpa roots' acetone extract on the antibacterial activity of gentamycin was evaluated against Staphylococcus aureus. Disc diffusion and broth dilution methods were used to determine the antibacterial activity of gentamycin in the absence and
Leachianone G (LG) 2"-dimethylallyltransferase, a novel prenyl side-chain elongation enzyme, was identified in Sophora flavescens Ait. cultured cells. The enzyme transfers a dimethylallyl group to the 2" position of another dimethylallyl group attached at position 8 of LG to form sophoraflavanone G,
Sophoraflavanone G (SG) was isolated from Sophora flavescens. Previously, we have found that SG is able to suppress the inflammatory response in lipopolysaccharide-stimulated RAW 264.7 macrophages. This study aimed to evaluate the effects of SG on apoptosis, and explore its molecular mechanism in
BACKGROUND
Sophora flavescens AITON (Leguminosae) is a typical traditional Korean medical herb considered to exhibit antibacterial, anti-inflammatory, and antipyretic effects, and is also used for the treatment of skin and mucosal ulcers, sores, diarrhea, gastrointestinal hemorrhage, arrhythmia, and
Sophoraflavanone G (5,7,2',4'-tetrahydroxy-8-lavandulylflavanone) has been referred as a phytochemical with the intensive antibacterial activity. To elucidate the pharmacological mechanism underlying an antibacterial action, sophoraflavanone G was isolated from Sophora exigua, thereafter its effect
Previously, several prenylated flavonoids having a C-8 lavandulyl moiety were found to inhibit cyclooxygenase-1 (COX-1) as well as 5-lipoxygenase (5-LOX), and sophoraflavanone G was the most potent inhibitor against these eicosanoid generating enzymes among 19 prenylated flavonoids tested. In this
BACKGROUND
Neuroinflammation plays a vital role in Alzheimer's disease (AD) and other neurodegenerative conditions. Sophora alopecuroides is widely used in traditional Uighur's medicine for the treatment of inflammation. Sophoraflavanone G (SG), a major flavonoid found in the S. alopecuroides, has
