In this study, new 1-ethyl-2-substituted-5-(methylsulfonyl)-1H-benzimidazole derivatives were designed and synthesized as computer-aided potential MAO-A and -B inhibitors. Compounds E6 and E10 were found more active than reference compound moclobemide with IC50 (µM)= 0.096 ± 0.003 and 0.150 ± 0.006 against MAO-A, respectively. Compound E5, on the other hand, exhibited an activity close to the reference
在这项研究中,设计并合成了新的 1-乙基-2-取代-5-(甲基磺酰基)-1 H-苯并咪唑衍生物,作为计算机辅助潜在的 MAO-A 和 -B 抑制剂。发现化合物E6和E10比参考化合物吗氯贝胺更具活性,对 MAO-A 的 IC 50 (µM)= 0.096 ± 0.003 和 0.150 ± 0.006 分别为。另一方面,化合物E5表现出接近参考司来吉兰的活性,对 MAO-B 的 IC 50 (μM)= 0.045 ± 0.002。通过分子对接方法和化合物E5、E6和E10的蛋白质-配体相互作用,这些化合物被鉴定为潜在的抑制剂进行了描述。通过分子动力学模拟揭示了MAO-B-E5复合物配体在活性位点的稳定性。已经开发了比较分子场分析 (CoMFA) 模型来识别允许抑制 MAO-A 和 -B 的关键结构片段。对化合物进行了理论ADME计算,发现它们符合限制规则。为了详细阐明化合物结构,进行了E4化合物的
