  摘要：

  Within a project aimed at discovering new Flaviviridae inhibitors, new variously substituted 2-phenylbenzimidazoles were synthesized and evaluated in cell-based assays for cytotoxicity and antiviral activity against viruses representatives of the three genera of the Flaviviridae family, i.e.: Pestivirus (BVDV), Flavivirus (YFV) and Hepacivirus (HCV). Title compounds were also tested against RNA viruses representative of other single-stranded, positive-sense (ssRNA(+)) negative-sense (RNA(-)), or double-stranded (dsRNA) genomes, as well as against representatives of two DNA virus families.Nine compounds showed activity against BVDV (EC50 = 0.8-8.0 mu M), compound 31 being the most potent (EC50 = 0.80 mu M) and selective (SI = CC50/EC50 = >100). When tested in an HCV replicon assay, compound 31 resulted again the most potent, displaying an EC50 value of 1.11 mu M and an SI of 100. Besides inhibiting BVDV, two compounds (35 and 38) showed a moderate activity also against YFV (EC50 = 13 mu M). Interestingly, 35 was moderately active also against RSV (EC50 = 25 mu M).

  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。
