We designed and synthesized 18 substituted indole derivatives containing a triazole scaffold as novel anti-influenza A virus candidates using a bio-isosteric and scaffold-hopping strategy from the lead compound 4-32-2. Most of the target compounds (eg: 6, 7a, 7d, 7f-j, 7l, 7m, 7o, 7q) exhibited potent anti-influenza A virus activity and low cytotoxicity in vitro. In particular, 7a exhibited the most potent anti-IAV activity (IC: 1.34 ± 0.13 μM) with low cytotoxicity (CC: > 100 μM), and high selectivity index (SI: > 74.63), which provides a new chemical scaffold for the development of novel anti-IAV drug.
我们设计并合成了 18 种含有三唑支架的取代吲哚衍生物，作为新型抗流感 A 病毒候选物，使用了先导化合物 4-32-2 的生物等排和支架跳跃策略。大多数目标化合物（例如：6、7a、7d、7f-j、7l、7m、7o、7q）在体外表现出很强的抗流感 A 病毒活性和低细胞毒性。特别是 7a 表现出最强的抗 IAV 活性（IC：1.34±0.13 μM），细胞毒性低（CC：>100 μM），选择性指数高（SI：>74.63），为开发新型抗 IAV 药物提供了新的化学结构。
