campaign, is the only drug approved, so far, for the treatment of the infection. Nevertheless, WHO in later 2020 has recommended against its use in COVID-19. In the present paper, we describe a step-by-step in silico design of a small library of compounds as main protease (Mpro) inhibitors. All the molecules were screened by an enzymatic assay on Mpro and, then, cellular activity was evaluated using Vero
从最近的 2019 年开始,由 SARS-CoV-2 病原体引起的 COVID-19 大流行导致了上个世纪最严重的健康-社会-经济灾难。尽管付出了巨大的科学努力,主要集中在疫苗的开发上,但有效且有效的抗 SARS-CoV-2 疗法的鉴定仍然是一个未满足的需求。Remdesivir 是一种从再利用运动中选出的抗埃博拉药物,是迄今为止唯一获准用于治疗感染的药物。尽管如此,世卫组织在 2020 年晚些时候建议不要将其用于 COVID-19。在本文中,我们描述了作为主要蛋白酶 (M pro ) 抑制剂的小型化合物库的计算机设计的逐步过程。通过对 M pro 的酶促测定筛选所有分子然后,使用 Vero 细胞病毒感染模型评估细胞活性。细胞筛选显示化合物29和34在无毒浓度(0.32 < EC 50 < 5.98 μM)下作为体外 SARS-CoV-2 复制抑制剂。为了使这些结果合理化,进行了额外的体外测定,重点关注木瓜蛋白酶样蛋白酶
