mechanics-generalized born surface area, and molecular dynamic method in order to uncover the binding mode interaction and their proposed impact on the active site environment and flexibility. The synthesized compounds were characterized by spectroscopic methods. Compound 3-Imino-1-pentyl indolin-2-one (3h) with the highest free binding energy adopts an extended conformation spanning from the flavin ring location
单胺氧化酶 B (MAO-B) 是开发神经保护剂治疗神经退行性疾病的有吸引力的药物靶点。目前的研究涉及合成、计算机模拟和细胞毒性评估 N1-烷基化-5-取代的 3-亚氨基靛红衍生物与提议的 MAO-B 抑制活性。通过诱导拟合对接、分子力学-广义出生表面积和分子动力学方法进行了计算机模拟分子建模研究,以揭示结合模式相互作用及其对活性位点环境和灵活性的影响。合成的化合物通过光谱方法表征。化合物 3-Imino-1-pentyl indolin-2-one (3h)具有最高自由结合能的结构采用从黄素环位置到基底腔入口的扩展构象。这样,Ile199 采用了“开放”构象,使 MAO-B 活性位点的两个独立腔融合形成一个单一空间,使化合物能够延伸到 MAO-B 入口腔空间。考虑到本文提供的数据,我们发现更长的N 1 -烷基化-3-亚氨基靛红衍生物可以作为抑制剂,占据 MAO-B 活性位点的两个空腔。此外,基于计算机
