optimization campaign, several quinazoline derivatives with potent antiviral efficacy (EC50: ∼0.1 μM) and high selectivity (SI > 1000) were successfully identified. The preliminary mechanism of action study indicated that such quinazoline derivatives functioned at the early stage of infection. In aggregate, this work delivered a new chemical type of coronavirus inhibitors, which could be employed not only for
临床上治疗冠状病毒感染的需求仍有很大未满足,迫切需要开发新型抗病毒药物。在这项工作中,针对我们内部化合物库的表型筛选鉴定了几种对HCoV-OC43 具有中等抗病毒活性的木豆碱衍生物。基于木豆碱的支架,采用支架跳跃策略设计了一系列喹唑啉衍生物。经过反复的结构优化活动,成功鉴定了几种具有有效抗病毒功效(EC50初步作用机制研究表明,此类喹唑啉衍生物在感染早期发挥作用。总的来说,这项工作提供了一种新型化学类型的冠状病毒抑制剂,它不仅可以用于进一步开发抗病毒药物,而且可以作为确定作用靶点的重要化学工具。
