benzoyl acetonitriles or aryl aldehydes, were helpful to construct the pyrazolo[3,4-b]pyridinones. The reaction media PEG2000/H2O was successfully recycled and reused at least 5 times without any obvious decrease in yield. The anti-influenza activities of the derivatives were evaluated and the screening results highlighted two derivatives, which exhibited strong inhibitory activity against H5N1 pseudovirus
通过在一个锅中前所未有地构建两个环和五个新键,开发了一种用于合成吡唑并[3,4- b ]吡啶酮的简便且通用的“水上”方案。证明水是该反应的重要促进剂,并且发现PEG2000在产率方面改善了反应。新合成了32种衍生物,其中大多数在一小时内即可制备。范围和局限性表明,在合成子,取代的苯甲酰基乙腈或芳基醛上取代的吸电子基团有助于构建吡唑并[3,4- b ]吡啶酮。反应介质PEG2000 / H 2O已成功回收并至少重复使用了5次,而收率没有明显下降。评估了这些衍生物的抗流感活性,筛选结果突出了两种衍生物,它们对H5N1假病毒表现出强大的抑制活性。这些积极的生物测定结果表明,可以以生态友好的方式快速制备潜在的抗流感病毒药物候选物库,并为药物化学家提供了新的药物发现见解。
