Nonstructural protein 5A (NS5A) represents a novel target for the treatment of hepatitis C virus (HCV). Daclatasvir, recently reported by Bristol–Myers–Squibb, is a potent NS5A inhibitor currently under investigation in phase 3 clinical trials. While the performance of daclatasvir has been impressive, the emergence of resistance could prove problematic and as such, improved analogues are being sought
非结构蛋白 5A (NS5A) 是治疗丙型肝炎病毒 (HCV) 的新靶点。百时美施贵宝最近报道的 Daclatasvir 是一种有效的 NS5A 抑制剂,目前正在 3 期临床试验中进行研究。虽然 daclatasvir 的表现令人印象深刻,但耐药性的出现可能会带来问题,因此,正在寻求改进的类似物。通过改变 daclatasvir 的联苯-咪唑单元,鉴定出新的 HCV NS5A 抑制剂,其对病毒突变株的耐药性得到改善,同时保留了 daclatasvir 的皮摩尔效力。特别是一种化合物,甲基 (( S )-1-(( S )-2-(4-(4-(6-(2-(( S )-1-((甲氧羰基) -L-缬氨酰)吡咯烷-2-基)-1 H-咪唑-5-基)喹喔啉-2-基)苯基) -1H-咪唑-2-基)吡咯烷-1-基)-3-甲基-1- oxobutan-2-yl)carbamate ( 17 ),表现出非常有前景
