The paper describes the bioassay-guided isolation, structure elucidation and anticancer evaluation of five flavonoids (-)-liquiritigenin (1), (-)-neoliquiritin (2), isoliquiritigenin (3), isoliquiritin (4) and formononetin (5) from the twigs of Jacaranda obtusifolia H. B. K. ssp. rhombifolia (G. F. W. Meijer) Gentry. The structures were elucidated based on ¹H, ¹³C NMR, comprehensive 2D NMR, MS ...
The androgen receptor (AR) signaling pathway continues to be active in hormone resistant prostate cancer (HRPC) and can inappropriately activate transcription. Consequently the AR is a therapeutic target for HRPC. We reported that PC-SPES is active against HRPC, partly due to its actions in down-regulating AR protein expression and modulating cell cycle. Further investigation has identified fiv...
Binding of phytoestrogens to rat uterine estrogen receptors and human sex hormone-binding globulins.
The interaction of phytoestrogens with the most important binding sites of steroid hormones, i.e. sex hormone-binding globulin and estrogen receptors, was investigated. Relative binding affinities and association constants for 21 compounds among them isoflavones, flavones, flavonols, flavanones, chalcones and lignans were determined. The lignan nordihydroguaiaretic acid weakly displaced 17beta-...
Glycyrrhiza uralensis Fisch. (G. uralensis) is one of the most widely used herbal medicines for the treatment of cough, spasms, pain, inflammation and low immunity This study was designed to enrich total flavonoids (TFF) from G. uralensis and investigate the anti-inflammatory activity of TFF. The anti-inflammatory activity was evaluated by inflammatory models of dimethylbenzene (DMB)-induced ea...
