A series of novel N-phenylbenzamide derivatives were synthesized and their anti-EV 71 activities were assayed in vitro. Among the compounds tested, 3-amino-N-(4-bromophenyl)-4-methoxybenzamide (1e) was active against the EV 71 strains tested at low micromolar concentrations, with IC50 values ranging from 5.7 ± 0.8–12 ± 1.2 μM, and its cytotoxicity to Vero cells (TC50 = 620 ± 0.0 μM) was far lower than that of pirodavir (TC50 = 31 ± 2.2 μM). Based on these results, compound 1e is a promising lead compound for the development of anti-EV 71 drugs.
一系列新型N-苯基苯酰胺衍生物被合成,并在体外检测了它们的抗EV 71活性。在测试的化合物中,3-氨基-N-(4-溴苯基)-4-甲氧基苯酰胺(1e)在低微摩尔浓度下对所测试的EV 71菌株表现出活性,IC50值范围为5.7 ± 0.8–12 ± 1.2 μM,其对Vero细胞的细胞毒性(TC50 = 620 ± 0.0 μM)远低于皮罗达韦(TC50 = 31 ± 2.2 μM)。基于这些结果,化合物1e是开发抗EV 71药物的有前景的先导化合物。
