生物活性
Polydatin (Piceid), extracted from the roots of Reynoutria japonica, a widely used traditional Chinese remedies, possesses anti-inflammatory activity in several experimental models. Polydatin (Piceid) inhibits G6PD and induces oxidative and ER stresses.
IC50 & Target
NF-κB, Autophagy
體外研究(In Vitro)
Polydatin protects cerebral cells from ischemic damages via improvement of microcirculation and inhibition of platelet aggregation. In addition, polydatin inhibits ICAM-1 expression in endothelial cells stimulated by lipopolysaccharide; it also attenuates adhesion between white blood cells and endothelial cells[1].
Polydatin inhibits cancer cell proliferation and cell cycle progression[4].
Polydatin induces ER stress-driven cell death[4].
體內(nèi)研究(In Vivo)
Polydatin could significantly increase the activity of SOD and the heart rate, attenuate myocardial pathological damage, decrease MDA content, slightly increase arterial pressure and GSH-Px activity, reduce intervals of QRS, QT and ST, and lower FFA content[2].
