RNA病毒感染,包括由呼吸道合胞病毒(RSV)、严重急性呼吸道综合征冠状病毒2(SARS-CoV-2)和委内瑞拉马脑炎病毒(VEEV)引起的RNA病毒感染,构成了一个重大的全球健康挑战。本文报道了一系列靶向RSV、SARS-CoV-2和/或VEEV的吡咯并[2,3-B]吡啶类化合物的合成和筛选。从该活动中,产生了一系列先导化合物,这些化合物在低个位数微摩尔范围内对各种病毒表现出抗病毒活性,并且没有显示出细胞毒性。这些发现突出了3-炔基-5-芳基-7-氮杂-吲哚作为一种有前途的化学型用于开发广谱抗病毒剂的潜力。
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-b]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.
