Substituted benzimidazolo[2,1‐b]benzo[e]thiazepin‐5(10H)‐one derivatives were prepared in moderate to good yield by reaction of mercapto benzimidazole derivatives with 2‐chloromethylbenzoyl chloride as a coupling component. Their structures were confirmed by elemental analysis, IR, NMR, and MS. Their antioxidant properties were evaluated by several methods: scavenging effect on 1,1‐diphenyl‐2‐picrylhydrazyl
通过巯基苯并咪唑衍生物与作为偶联组分的 2-氯甲基苯甲酰氯反应,以中等至良好的收率制备了取代的苯并咪唑并 [2,1-b] 苯并 [e] thiazepine-5 (10H)-one 衍生物。它们的结构经元素分析、红外、核磁共振和质谱证实。它们的抗氧化性能通过几种方法进行评估:对 1,1-二苯基-2-苦基肼 (DPPH) 自由基的清除作用、还原能力测定和脂质过氧化的抑制。在DPPH测定中,3h表现出比trolox强的活性。在还原力测定和脂质过氧化抑制中,化合物3a的活性高于3h,与trolox相似。还测定了抗糖尿病作用,抗糖尿病活性与其抗氧化特性相关,
