The synthesis of antioxidant compounds bearing pharmacologically active groups has become a research interest in the last decade. A series of hydrazones containing a butylated hydroxyl group were synthesized from 2‐((3,5‐di‐tert‐butyl‐4‐hydroxybenzyl)thio)acetohydrazide and various benzaldehyde derivatives, and their radical scavenging activity was explored by 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) assay
在过去的十年中,带有药理活性基团的抗氧化剂化合物的合成已成为研究兴趣。由2-((3,5-二叔丁基-4-羟基苄基)硫代)乙酰肼和各种苯甲醛衍生物合成了一系列含丁基羟基的,并通过2,2-探索了它们的自由基清除活性。二苯基-1-吡啶甲基肼(DPPH)测定和计算计算。根据结果,讨论了不同取代基对DPPH IC 50值的影响。OH和N的键离解焓(BDE)使用密度泛函理论(DFT)计算化合物的H键和自旋密度(SD)值,以确定作为自由基清除剂的理论能力。根据结果,还讨论了硫醚基和NH键旁边的取代基对BDE值的影响。
