polyhydroxylated (E)‐stilbenes were synthesized by Mizoroki–Heck reactions and tested for their ability to act as radical scavenger. One of the 56 stilbenes included in this study and investigated in DPPH assays gave an SC50 value of 11.0 μM, hence exhibiting an about 9.3 times higher activity than resveratrol. As shown in a photometric SRB assay using mouse NiH 3T3 fibroblasts, this compound is not cytotoxic up
通过 Mizoroki-Heck 反应合成了高度取代的多羟基化 (E)-二苯乙烯,并测试了它们作为自由基清除剂的能力。本研究中包括并在 DPPH 测定中研究的 56 种芪中之一的 SC50 值为 11.0 μM,因此其活性比白藜芦醇高约 9.3 倍。如使用小鼠 NiH 3T3 成纤维细胞的光度 SRB 测定所示,该化合物在浓度小于 30 μM 时没有细胞毒性。
