There are currently no approved vaccines or small molecule therapeutics available for the prophylaxis or treatment of Middle East Respiratory Syndrome coronavirus (MERS-CoV) infections. MERS-CoV 3CL protease is essential for viral replication; consequently, it is an attractive target that provides a potentially effective means of developing small molecule therapeutics for combatting MERS-CoV. We describe
目前尚无批准的疫苗或小分子疗法可用于预防或治疗中东呼吸综合征冠状病毒(MERS-CoV)感染。 MERS-CoV 3CL 蛋白酶对于病毒复制至关重要;因此,它是一个有吸引力的靶点,为开发对抗中东呼吸综合征冠状病毒的小分子疗法提供了潜在的有效手段。我们在此描述了一类新型 MERS-CoV 3CL 蛋白酶抑制剂的结构引导设计和评估,该抑制剂以哌啶部分作为设计元素,非常适合利用有利的亚位点结合相互作用来获得最佳的药理活性和 PK 特性。使用 X 射线晶体学阐明了化合物的作用机制以及与结合相关的结构决定因素。
