During a random screening of representative libraries of nucleoside analogues we discovered that the adenine derivatives FEVB28 and FEG118 were Flaviviridae inhibitors endowed with potency comparable, if not superior, to that of ribavirin. Those studies prompted us to design a new class of protected nucleoside analogs, reported herein, which displays interesting anti-bovine viral diarrhea virus (BVDV)
在对代表性核苷类似物文库的随机筛选中,我们发现腺嘌呤衍生物FEVB28和FEG118是黄病毒科抑制剂,具有与利巴韦林相当的效力,甚至更高。这些研究促使我们设计了本文所报道的新型受保护的核苷类似物,其在基于细胞的测定中显示出有趣的抗牛病毒性腹泻病毒(BVDV)活性和低细胞毒性(4,23,29 EC(50):14分别为11、26 microM,CC(50)> 100 microM)和针对BVDV的RNA依赖性RNA聚合酶(RdRp)的酶分析中的显着活性(分别为4、23、29,RdRp抑制活性27、16、15 microM) 。
