network among the key substructures. This drew the optimization of our design strategy to discover potent and reversible inhibitors of human acetylcholinesterase and butyrylcholinesterase (hAChE and hBuChE) that selectively interact with specific protein substructures. Accordingly, two tricyclic moieties differently spaced by functionalized linkers were investigated as molecular yardsticks to probe the
蛋白质构象波动对于生物学功能至关重要,尽管蛋白质运动与功能之间的关系尚待充分研究。通过对胆碱酯酶(ChEs)的全面生物信息学分析,我们确定了引起蛋白质波动和功能的特定热点,以及在关键子结构之间调节合作网络的活性位点残基。这吸引了我们设计策略的优化,以发现有效和可逆的人类乙酰胆碱酯酶和丁酰胆碱酯酶抑制剂(hAChE和hBuChE),这些抑制剂可选择性地与特定蛋白质亚结构相互作用。因此,研究了两个功能不同的连接基间隔不同的三环部分作为分子尺度,以探讨与hChE峡谷中特定热点的最佳相互作用。确定了许多SAR趋势,发现多位点抑制剂3a和3d是迄今为止已知的最有效的hBuChE和hAChE抑制剂。
