a result of our previous research focussed on benzimidazoles, herein we present design, synthesis, QSAR analysis and biological activity of novel N-substituted benzimidazole derived carboxamides. Carboxamides were designed to study the influence of the number of methoxy groups, the type of the substituent placed at the benzimidazole core on biological activity. Pronounced antioxidative activity displayed
摘要 由于我们之前的研究集中在苯并咪唑上,在此我们介绍了新型 N 取代苯并咪唑衍生甲酰胺的设计、合成、QSAR 分析和生物活性。Carboxamides 旨在研究甲氧基数量、苯并咪唑核心上的取代基类型对生物活性的影响。显着的抗氧化活性显示出未取代的28 (IC 50 ≈ 3.78 mM, 538.81 mmolFe 2+ /mmolC) 和二甲氧基取代的衍生物34 (IC 50 ≈ 5.68 mM, 618.10 mmolFe 2+ /mmolC)。三甲氧基取代的43和未取代的化合物40在 N 原子上具有异丁基侧链的 HCT116(IC 50 ≈ 0.6 µM,两者)和 H 460 细胞(IC 50 ≈ 2.5 µM;0.4 µM)具有很强的活性,对非肿瘤细胞的细胞毒性较小。细胞中的抗氧化活性通常证实了在衍生物34和40的 DPPH/FRAP 测定中获得的相对适度的抗氧化能力。生成
