omen-7-yloxy) acetic acid hydrazide 3. Evaluation of the target compounds for their antiviral activity against hepatitis A virus revealed that the ethylthiosemicarbazide derivative 7b was the most potent virucidal agent (IC50 = 3.1 μg/ml, TI = 83). The Schiff's bases 14c and 14b demonstrated the highest virustatic effects against viral adsorption and replication, respectively (14c; IC50 = 8.5 μg/ml
从(2-oxo-4-phenyl-2 H -chromen-7-yloxy)乙酰肼3合成了一系列新的4-苯基香豆素衍生物。评估目标化合物对甲型肝炎病毒的抗病毒活性后发现,乙基硫代氨基脲衍生物7b是最有效的杀病毒剂(IC 50 = 3.1μg/ ml,TI = 83)。席夫氏碱14c和14b分别表现出对病毒吸附和复制的最高病毒学作用(14c ; IC 50 = 8.5μg / ml,TI = 88和14b ; IC50 = 10.7μg/ ml, TI = 91)。此外,测试了化合物7b, 14b和14c针对HAV 3C蛋白酶,并显示出显着的抑制作用(分别为Ki = 1.903、0.104和0.217μM)。三种目标化合物对HAV 3C蛋白酶表现出的显着抑制作用促使我们扩展了对HRV 3C蛋白酶的研究,HRV 3C蛋白酶是同一家族的结构相关酶,有趣的是,这三种目标化合物对HRV
