Despite the continuing global crisis caused by coronavirus disease 2019 (COVID-19), there is still no effective treatment. Therefore, we designed and synthesized a novel series of 2-benzylaminoquinazolin-4(3)-one derivatives and demonstrated that they are effective against SARS-CoV-2. Among the synthesized derivatives, 7-chloro-2-(((4-chlorophenyl)(phenyl)methyl)amino)quinazolin-4(3)-one (Compound ) showed highest anti-SARS-CoV-2 activity, with a half-maximal inhibitory concentration value greater than that of remdesivir (IC = 4.2 μM vs. 7.6 μM, respectively), which gained urgent approval from the U.S. Food and Drug Administration. In addition, Compound showed good results in various assays measuring metabolic stability, human ether a-go-go, Cytochromes P450 (CYPs) inhibition, and plasma protein binding (PPB), and showed better solubility and pharmacokinetics than our previous work.
尽管2019冠状病毒病(COVID-19)引发的全球危机仍在持续,但仍没有有效的治疗方法。因此,我们设计并合成了一系列新型的2-苄基氨基喹唑啉-4(3)-酮衍生物,并证明它们对严重急性呼吸综合征冠状病毒2(SARS-CoV-2)有效。在合成的衍生物中,7-氯-2-(((4-氯苯基)(苯基)甲基)氨基)喹唑啉-4(3)-酮(化合物 )表现出最高的抗SARS-CoV-2活性,其半数最大抑制浓度值高于瑞德西韦(IC 分别为4.2 μM和7.6 μM),瑞德西韦已获得美国食品药品监督管理局的紧急批准。此外,化合物 在各种测量代谢稳定性、人醚-去极化相关基因、细胞色素P450(CYPs)抑制和血浆蛋白结合(PPB)的试验中均显示出良好的结果,并且比我们之前的工作表现出更好的溶解性和药代动力学。
