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

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

Characterization of leachianone G 2"-dimethylallyltransferase, a novel prenyl side-chain elongation enzyme for the formation of the lavandulyl group of sophoraflavanone G in Sophora flavescens Ait. cell suspension cultures.

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,

A compound isolated from Sophora flavescens-sophoraflavanone G (SG)-showed anti-tumor and anti-inflammatory properties. We previously demonstrated that SG promoted apoptosis in human leukemia HL-60 cells. In the present study, we investigated the effects of SG on apoptosis in human

Effects of sophoraflavanone G, a prenylated flavonoid from Sophora flavescens, on cyclooxygenase-2 and in vivo inflammatory response.

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

The bioassay-guided fractionation of the MeOH extract from the root of Sophora flavescens led to the isolation of eight known prenylated flavonoids ( 1 - 8) responsible for the IN VITRO anti-allergic activity. Among them, kushenol N ( 3), sophoraflavanone G ( 6), and leachianone A ( 7) demonstrated

As a part of the project for the Chinese Pharmacopoeia (2015 edition), the quality standard of Sophora flavescens root extract was investigated and established. According to the methods described in the Appendix of Chinese Pharmacopoeia (2010 edition), the water and ash inspections were carried out.

8-dimethylallylnaringenin (8-DMAN) 2'-hydroxylase, which is indispensable for the formation of a lavandulylated flavanone, sophoraflavanone G, was detected in cell suspension cultures of Sophora flavescens. The enzyme catalyzes the 2'-hydroxylation of 8-DMAN to leachianone G, and is tightly bound to
