A library of eighty-six assorted benzimidazole derivatives was screened for antiviral activity against a panel of ten RNA and DNA viruses. Fifty-two of them displayed different levels of activity against one or more viruses, among which CVB-5, RSV, BVDV and Sb-1 were the most frequently affected. In particular, fourteen compounds exhibited an EC50 in the range 9–17 μM (SI from 6 to >11) versus CVB-5
筛选了八十六种各种苯并咪唑衍生物的文库对十种RNA和DNA病毒的抗病毒活性。 其中有52个针对一种或多种病毒表现出不同水平的活性,其中CVB-5,RSV,BVDV和Sb-1受感染最频繁。特别是,与CVB-5相比,十四种化合物的EC 50为9–17μM(SI为6至> 11),七种化合物的EC 50为5–15μM(SI为6.7至⩾20) )对抗RSV,因此所产生的效果与相应的参考药物(NM108和利巴韦林)相当或更高。这些化合物大多数衍生自2-苄基苯并咪唑,也衍生自其他分子支架[例如1-苯基苯并咪唑(2),2-三氟甲基苯并咪唑(69),二氢吡啶并[3',2':4,5]咪唑[1,2- a ] [1,4]苯并二氮杂-5-酮(3),二苯并[ c ^,ë ]苯并咪唑[1,2一]氮杂(22),和2-(四氢-吡喃-2-基)苯并咪唑(81,82和86)]都与活动的针对这些有趣水平或其他病毒(BVDV,Sb-
