We report herein the synthesis of a series of novel quinoline derivatives, based on the lead compound 1a, identified from a rRSV-mGFP high-throughput screening assay. Our results revealed that target compounds 1b, 1g-h, 1af and 1ah (IC50 = 3.10–6.93 μM) had good in vitro activity against RSV, which were better than 1a and ribavirin. In addition, we found that compound 1g displayed the lower cytotoxicity
我们在此报告了基于前导化合物1a的一系列新型喹啉衍生物的合成,该化合物是根据rRSV-mGFP高通量筛选分析确定的。我们的结果表明目标化合物1b,1g-h,1af和1ah(IC 50 = 3.10–6.93μM)对RSV的体外活性良好,优于1a和利巴韦林。此外,我们发现化合物1g表现出较低的细胞毒性(CC 50:2490.33μM)和最高的选择性指数(SI = 673.06),表明其有望成为进一步开发的潜力。另一方面,化合物1a,1m,1v,1ad-1af和1ah-1ai(IC 50 s:1.87–14.28μM)的抗IAV活性高于或相当于利巴韦林(IC 50:15.36±0.93μM)。特别是,发现活性最高的化合物1ae(IC 50:1.87± 0.58μM)的效力是参考药物的8.2倍,可以在早期抑制病毒的转录和复制周期。
