result, an indole-based derivative, speculated to interact with the S4 binding pocket, 21b (IC50 = 1.5 ± 0.1 μM) was discovered. Its structure was further modified and evaluated in silico by combining docking simulation, free energy perturbation calculation and subpocket interaction analysis to optimize the interactions at the S2 and S4 binding pockets. Among the newly designed novel derivatives, 21h
严重急性呼吸综合征冠状病毒 2 (SARS-CoV-2) 主要蛋白酶 (M pro ) 已成为开发针对 COVID-19 感染的抗 SARS-CoV-2 药物的目标,因为 M pro处理必需的病毒多蛋白并发挥关键作用在 SARS-CoV-2 复制中的作用。在这项研究中,我们报告了源自卡莫氟的新型 SARS-CoV-2 M pro抑制剂的开发,卡莫氟是一种先前鉴定的化合物,作为 SARS-CoV-2 M pro的共价抑制剂显示出中等效力。为了采用结构引导的药物设计策略,首先通过对接模拟预测了卡莫氟在 M pro催化活性位点上的假定完整结合模式。基于预测的结合模式,对一系列旨在占据M pro底物结合区域的卡莫氟衍生物进行了构效关系分析。结果, 发现了一种基于吲哚的衍生物,推测与 S4 结合袋相互作用, 21b (IC 50 = 1.5 ± 0.1 μM)。通过结合对接模拟、自由能扰动计算和子口
