SARS CoV 3CL is known to be a promising target for development of therapeutic agents against the severe acute respiratory syndrome (SARS). A quinolinone compound was selected via virtual screening, and it was synthetized and tested for enzymatic inhibition . Compound showed potent inhibitory activity (IC=0.44 µmol/L) toward SARS CoV 3CL. Further work on a series of quinolinone derivatives resulted in the discovery of the most potent compound , inhibiting SARS CoV 3CL with an IC of 36.86 nmol/L. The structure-activity relationships were also discussed.
已知严重急性呼吸综合征冠状病毒(SARS-CoV)3CL是开发抗严重急性呼吸综合征(SARS)治疗药物的一个有前景的靶点。通过虚拟筛选选择了一种喹啉酮化合物,并对其进行合成和酶抑制测试。化合物对SARS-CoV 3CL表现出强效抑制活性(IC=0.44 μmol/L)。对一系列喹啉酮衍生物的进一步研究发现了最有效的化合物,其对SARS-CoV 3CL的抑制常数IC为36.86 nmol/L。还讨论了构效关系。
