effective antivirals to treat them. 2-Aminoquinazolin-4(3H)-one derivatives were newly designed, synthesized, and investigated to show the inhibitory effects on SARS-CoV-2 and MERS-CoV. Among the synthesized derivatives, 7-chloro-2-((3,5-dichlorophenyl)amino)quinazolin-4(3H)-one (9g) and 2-((3,5-dichlorophenyl)amino)-5-hydroxyquinazolin-4 (3H)-one (11e) showed the most potent anti-SARS-CoV-2 activities
尽管致命冠状病毒的威胁日益增加,但目前还没有经过证明有效的抗病毒药物可以治疗它们。新设计、合成并研究了 2-Aminoquinazolin-4(3 H )-one 衍生物,以显示对 SARS-CoV-2 和 MERS-CoV 的抑制作用。合成的衍生物中,7-氯-2-((3,5-二氯苯基)氨基)喹唑啉-4( 3H )-酮( 9g )和2-((3,5-二氯苯基)氨基)-5-羟基喹唑啉-4 (3 H )-one ( 11e ) 显示出最有效的抗 SARS-CoV-2 活性 (IC 50 < 0.25 μM) 和抗 MERS-CoV 活性 (IC 50 < 1.1 μM),且无细胞毒性( CC 50 > 25 μM)。此外,两种化合物在代谢稳定性、hERG 结合亲和力、CYP 抑制和初步 PK 研究方面均显示出可接受的结果。
