Seventy-six 2-phenylbenzimidazole derivatives were synthesized and evaluated in cell-based assays for cytotoxicity and antiviral activity against a panel of 10 RNA and DNA viruses. The most commonly affected viruses were, in decreasing order, CVB-2, BVDV, Sb-1, HSV-1, and YFV, while HIV-1 and VSV were not affected, and RSV, VV and Reo-1 were only susceptible to a few compounds. Thirty-nine compounds
合成了76种2-苯基苯并咪唑衍生物,并在基于细胞的测定中评估了其对一组10种RNA和DNA病毒的细胞毒性和抗病毒活性。受影响最严重的病毒以降序排列,分别是CVB-2,BVDV,Sb-1,HSV-1和YFV,而HIV-1和VSV不受影响,RSV,VV和Reo-1仅易感一些化合物。39种化合物表现出 对至少一种病毒的高活性(EC 50 = 0.1–10μM),其中四种对VV(24,EC 50 = 0.1μM)和BVDV(50,具有EC 50的51和53 分别为1.5、0.8和1.0μM)。最后的化合物在低微摩尔浓度下抑制BVDV和HCV的NS5B RdRp,后者与前者具有结构相似性。所考虑的化合物代表了针对痘病毒,瘟病毒甚至HCV(它们是重要的人类和兽医病原体)的抗病毒剂开发的诱人线索。
