Neohesperidin, a natural new nutrition sweetener, has antioxidant (IC50=22.31ug/mL), anti-inflammatory, and neuroprotective effects. It can attenuate cerebral ischemia-reperfusion injury via the inhibition of neuronal and oxidative stress through the regulation of the apoptotic pathway and activating the Akt/Nrf2/HO-1 pathway, it may be useful for the treatment and/or protection of gastritis.
Calycosin, a selective estrogen receptor modulator, is also a vasorelaxant and a noncompetitive Ca(2+) channel blocker. It has anti-oxidative, anti-inflammatory, hepatoprotective,antineoplastic, and effective skin-lightening activities. Calycosin exhibited tyrosinase inhibitory activity with an IC(50) value of 38.4 microM, it suppressed breast cancer cell growth via ERβ-dependent regulation of IGF-1R, p38 MAPK and PI3K/Akt pathways.
Calycosin-7-O-beta-D-glucoside, a melanin biosynthesis inhibitor, can protect BBB integrity in experimental cerebral ischemia–reperfusion injury via regulating NO/cav-1/MMPs pathway. It attenuates ischemia-reperfusion injuryin vivovia activation of the PI3K/Akt pathway, and has effects on cell apoptosis in cervical cancer HeLa cells and expression of Bcl-2/Bax.
1. Gardenin has regulatory effect on the gene expression in rats with focal cerebral ischemia.
Rotundine provides remarkable protection against cerebral ischemia reperfusion damage, its mechanisms may be through its influence on NO、ET 1 and energy metabolism. Rotundine injection can ameliorate the damages by modulating the activities of different types of NOS. It combined with methadone treatment may be a better therapeutic method in treatment of heroin dependence.
