values of these compounds were between 9 and 56. Besides, 6b, 6c and 6d also inhibited the replication of two other RNA viruses, Sindbis virus and respiratory syncytial virus, although these EC50 values were higher compared to those noted for Coxsackie B4 virus. The SAR analysis indicated that keeping the free thiosemicarbazide moiety is crucial to obtain this antiviral activity, since the cyclization
一系列新型吲哚氨基硫脲 (6a-6g) 及其环化产物 4-噻唑烷酮 (7a-7g) 已被设计、合成并在体外评估其对多种 DNA 和 RNA 病毒的抗病毒活性。化合物 6a、6b、6c 和 6d 对柯萨奇 B4 病毒表现出显着的抗病毒活性,EC50 值范围为 0.4 至 2.1 μg/mL。这些化合物的选择性指数(细胞毒性与抗病毒有效浓度之比)值在 9 和 56 之间。此外,6b、6c 和 6d 还抑制了另外两种 RNA 病毒、辛德比斯病毒和呼吸道合胞病毒的复制,尽管这些 EC50 值与柯萨奇 B4 病毒所指出的相比更高。SAR分析表明,保持游离氨基硫脲部分对于获得这种抗病毒活性至关重要,
