瑞德西韦抗新冠病毒吗?
印象中吉利公司生产的尚在研发阶段的原本目标为抗Ebola 病毒的瑞德西韦(Remdesivir)也能抗新冠病毒似乎早就
在谈瑞德西韦之前先来看一下新冠肺炎病毒的生命周期及人工抑制阻
瑞得西韦是做为抗Ebola病毒而研发合成的。第一篇科学论文发表于
筛选药物时的体外试管实验是检测抑制Ebola 病毒RNA-dependent RNA Polymerase (RdRp)复制合成病毒RNA的活性。瑞得西韦并不直接抑制
瑞得西韦抑制病毒RNA复制的特异性取决于病毒RdRp酶的蛋白
当然目前当务之急是搞清楚瑞得西韦 是否对新冠肺炎(或是对部分
"Expectations for the data in severe patients are modest, with the Jefferies analysts saying benefits in the 30% to 40% range are unlikely. That makes the May data on patients with moderate symptoms, a population that may be more responsive to remdesivir, perhaps the key determinants for the fate of the drug. Gilead has told investors not to base the company's future around the drug, but shares in the Big Biotech still jumped nearly 3% Monday morning.”
