Resveratrol is the subject of intense research as a natural antioxidant and cancer chemopreventive agent. There has been a great deal of interest and excitement in understanding its action mechanism and developing analogs with antioxidant and cancer chemoprevention activities superior to that of the parent compound in the past decade. This work delineates that elongation of the conjugated links is
白藜芦醇作为天然抗氧化剂和癌症化学预防剂是广泛研究的主题。在过去十年中,人们对它的作用机理以及开发出具有比母体化合物更好的抗氧化剂和癌症化学预防活性的类似物产生了极大的兴趣和激动。这项工作表明,共轭键的延长是提高白藜芦醇类似物抗氧化活性的重要策略,包括在均相溶液中的氢原子或电子供电能力以及在非均相介质中的抗溶血活性。更重要的是,与白藜芦醇相比,带有3,4'-二羟基基团的三烯C3作为重要的先导化合物浮出水面,显示出显着提高的抗氧化剂,细胞毒性和诱导细胞凋亡的活性。
