NATURE:大规模筛选,老药新用对抗SARS-CoV-2

2020-07-24 MedSci原创 MedSci原创

疫苗的开发很可能需要至少12-18个月的时间,而新型抗病毒疗法的典型批准时间可能超过10年。相比之下,已知药物的再利用可以显著加快COVID-19的新型疗法的开发。

2019年新型冠状病毒(SARS-CoV-2)的出现,引发了一场持续的全球重症肺炎样疾病大流行,其被命名为COVID-19

疫苗的开发很可能需要至少12-18个月的时间,而新型抗病毒疗法的典型批准时间可能超过10年。相比之下,已知药物的再利用可以显著加快COVID-19的新型疗法的开发。

为此,研究人员评测了一个包含约12,000个临床阶段或FDA批准的小分子的已知药物库。

其报告了100种抑制病毒复制的分子的鉴定,包括21种表现出剂量反应关系的已知药物。其中,研究人员发现,13个分子表现出可能与患者可达到的治疗剂量相称的有效浓度,包括PIKfyve激酶抑制剂apilimod,以及半胱氨酸蛋白酶抑制剂MDL-28170、Z LVG CHN2、VBY-825和ONO 5334。

值得注意的是,MDL-28170、ONO 5334和apilimod被发现可以拮抗病毒在人iPSC衍生的肺细胞样细胞中的复制,PIKfyve抑制剂也在原发性人肺移植模型中表现出抗病毒的功效。

由于本研究中发现的大部分分子已经进入临床,这些化合物具有已知的药理和人体安全性特征,这将加速这些药物治疗COVID-19的临床前和临床评价。
