(RO-0529, AK0529) is reported here for the first time as a promising respiratory syncytial virus (RSV) fusion (F) protein inhibitor that currently is in phase 2 clinical trials. This article describes the process of RO-0529 as a potent, selective, and orally bioavailable RSV F protein inhibitor and highlights the in vitro and in vivo anti-RSV activities and pharmacokinetics in animal species. RO-0529 demonstrates
Ziresovir(RO-0529,AK0529)首次报道为有希望的呼吸道合胞病毒(RSV)融合(F)蛋白
抑制剂,目前处于2期临床试验中。本文介绍了RO-0529作为有效,选择性和口服可
生物利用的RSV F蛋白
抑制剂的过程,并重点介绍了动物体内和体外的抗RSV活性和药代动力学。RO-0529在
细胞分析中显示出对实验室菌株以及RSV临床分离株的个位数nM
EC50效能,并且在RSV病毒感染的BALB / c小鼠模型中病毒载量减少了一个以上。通过鉴定RSV F蛋白中的
D486N,
D489V和
D489Y的耐药突变以及在
细胞分析中抑制RSV F蛋白诱导的细胞-细胞融合,证明RO-0529是一种特定的RSV F蛋白
抑制剂。
