experimental results indicate that of the twenty newly synthesized imidazole-coumarin conjugates, three of them exhibited appealing EC50 values (5.1-8.4 μM) and selective indices >20 against hepatitis C virus. Their potency and selectivity were increased substantially by modification of their structure with two factors: imidazole nucleus with a hydrogen atom at the N(1) position and coumarin nucleus

化学方法合成了一系列带有-SCH2-键的新型共轭化合物。实验结果表明,在二十种新合成的
咪唑-
香豆素缀合物中,其中三种表现出吸引人的
EC50 值 (5.1-8.4 μM) 和针对丙型肝炎病毒的选择性指数 >20。通过用两个因素修改其结构,它们的效力和选择性得到显着提高:在 N(1) 位置带有氢原子的
咪唑核和带有取代基(例如 Cl、F、Br、Me 和 OMe)的
香豆素核。这些指南为进一步开发作为抗病毒剂的共轭化合物提供了有价值的信息。
