设计、合成了一系列可能作为SARS-CoV 3CL蛋白酶抑制剂的吡唑酮类化合物,并利用荧光底物肽进行了体外蛋白酶测定,其中一些化合物对3CL蛋白酶表现出有效的抑制作用。有趣的是,其中一种抑制剂对柯萨奇病毒B3的3C蛋白酶也有活性。这些抑制剂有潜力开发成抗冠状病毒和抗小核糖核酸病毒的药物。设计、合成了一系列可能作为SARS-CoV 3CL蛋白酶抑制剂的吡唑酮类化合物,并利用荧光底物肽进行了体外蛋白酶测定,其中一些化合物对3CL蛋白酶表现出有效的抑制作用。有趣的是,其中一种抑制剂对柯萨奇病毒B3的3C蛋白酶也有活性。这些抑制剂有潜力开发成抗冠状病毒和抗小核糖核酸病毒的药物。
A series of pyrazolone compounds as possible SARS-CoV 3CL protease inhibitors were designed, synthesized, and evaluated by in vitro protease assay using fluorogenic substrate peptide in which several showed potent inhibition against the 3CL protease. Interestingly, one of the inhibitors was also active against 3C protease from coxsackievirus B3. These inhibitors could be potentially developed into anti-coronaviral and anti-picornaviral agents.
