biomedical applications, a structural modification of the resveratrol scaffold was carried out. Six trans-resveratrol (TR) analogs with a trans-stilbazole framework were obtained. Quantum calculations based on the density functional theory (DFT) were used to study the relationship between the structure of synthesized compounds and antioxidant activity. Calculations have shown that derivatives 2b, 2c, and
在寻找用于生物医学应用的更强大和通用的抗氧化剂时,对白藜芦醇支架进行了结构修饰。获得了具有反式-斯蒂巴唑骨架的六个反式-白藜芦醇(TR)类似物。基于密度泛函理论(DFT)的量子计算用于研究合成化合物的结构与抗氧化剂活性之间的关系。计算表明,衍生物2b,2c和2e的抗氧化活性应高于TR,而2a,2d和3a是不太有效的抗氧化剂。所获得的数据与用二苯基-1-吡啶并肼基(DPPH)进行的分析结果很好地相关。在小鼠成纤维细胞L929的MTT测试中,与TR相比,所有化合物均显示出较低的细胞毒性。
