Generally, the final compounds exhibited moderate to good AChE or BuChE inhibitory activity. Among them, 3g and 3j showed the most potent activity against AChE (IC50 = 4.32 µM) and BuChE (IC50 = 1.27 µM), respectively. The kinetic results showed that both compounds exhibited mixed-type inhibition. Among the selected compounds, nitro derivatives (3g, 4g, and 5g) provided better Aβ42 inhibition. According to
设计并合成了一系列哌啶氮上带有苯乙基、苯丙基和苯丁基取代基的哌啶-3-碳酰肼-腙作为胆碱酯酶 (ChE) 抑制剂。筛选标题化合物的乙酰胆碱酯酶 (AChE)、丁酰胆碱酯酶 (BuChE) 抑制活性和抗氧化能力,以及 Aβ 42的活性化合物自聚集抑制,体外。化学发光法用于确定所选化合物对脑组织中活性氧 (ROS) 水平的影响。通过 MOE 程序计算物理化学性质。还对最活跃的化合物进行了动力学分析和分子建模研究。通常,最终化合物表现出中等至良好的 AChE 或 BuChE 抑制活性。其中,3g和3j分别对 AChE (IC 50 = 4.32 µM) 和 BuChE (IC 50 = 1.27 µM)显示出最有效的活性 。动力学结果表明,两种化合物均表现出混合型抑制作用。在选定的化合物中,硝基衍生物(3g、4g和 5g ) 提供更好的 Aβ 42抑制。根据化学发光分析,4i表现出最活跃的超氧
