Resveratrol (Res) has long been discovered to have antioxidant effects to prevent such as oxidation, inflammation, neurodegeneration and age-related diseases. However, its poor water solubility, low bioavailability and instability have become a barrier to its pharmaceutical application. In order to improve the neuroprotective effects and develop more potential usage of Res, three Res derivatives containing one or two glucose groups, i.e., Res-Glu1, Res-Glu2 and Res-Glu3, were designed and synthesized through click reaction. Res-Glu1, Res-Glu2 and Res-Glu3 were tested being better water solubility and stability compared to Res. Res derivatives reduced •OH radicals-induced DNA damage. PC12 assays indicated that glucosylated Res derivatives could alleviate HO-induced neurotoxicity and reduce intracellular ROS generation, demonstrating their neuroprotective effects. In addition, Res derivatives enhanced the protective effects on cerebral ischemia-reperfusion injury in rats. Res-Glu3 displayed the best neuroprotective effects among the three derivatives.
长期以来,人们发现白藜芦醇(Res)具有抗氧化作用,可预防氧化、炎症、神经退行性变和与年龄相关的疾病。然而,其水溶性差、生物利用度低和稳定性差已成为其药物应用的障碍。为了提高白藜芦醇的神经保护作用并开发其更多潜在用途,通过点击反应设计并合成了三种含有一个或两个葡萄糖基团的白藜芦醇衍生物,即Res-Glu1、Res-Glu2和Res-Glu3。与白藜芦醇相比,Res-Glu1、Res-Glu2和Res-Glu3的水溶性和稳定性更好。白藜芦醇衍生物可减少•OH自由基诱导的DNA损伤。PC12实验表明,糖基化白藜芦醇衍生物可减轻HO诱导的神经毒性并减少细胞内ROS的产生,证明了它们的神经保护作用。此外,白藜芦醇衍生物增强了对大鼠脑缺血再灌注损伤的保护作用。Res-Glu3在三种衍生物中表现出最佳的神经保护作用。
