RNA viral infections, including those caused by respiratory syncytial virus (RSV), severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and Venezuelan Equine encephalitis virus (VEEV), pose a major global health challenge. Here, we report the synthesis and screening of a series of pyrrolo[2,3-]pyridines targeting RSV, SARS-CoV-2 and/or VEEV. From this campaign, a series of lead compounds was generated that demonstrated antiviral activity in the low single-digit micromolar range against the various viruses and did not show cytotoxicity. These findings highlight the potential of 3-alkynyl-5-aryl-7-aza-indoles as a promising chemotype for the development of broad-spectrum antiviral agents.
包括由呼吸道合胞病毒（RSV）、严重急性呼吸综合征冠状病毒2（SARS-CoV-2）和委内瑞拉马脑炎病毒（VEEV）引起的感染在内的RNA病毒感染，构成了一项重大的全球健康挑战。在此，我们报告了一系列针对RSV、SARS-CoV-2和/或VEEV的吡咯并[2,3 -]吡啶的合成与筛选。通过这项研究，产生了一系列先导化合物，它们对各种病毒表现出低个位数微摩尔范围内的抗病毒活性，并且未显示出细胞毒性。这些发现突出了3 - 炔基 - 5 - 芳基 - 7 - 氮杂吲哚作为开发广谱抗病毒药物的一种有前景的化学类型的潜力。
