the antiviral activity of thiopyrano[2,3-b]quinolines is notably affected by both the nature and position of the substituent within the tetrazole ring, as well as the substituent within the benzene moiety of quinoline. These findings contribute to the further search for new antiviral agents against influenza A viruses among derivatives of thiopyrano[2,3-b]quinoline.
开发了一种使用 thio-Michael 和 aza-Morita-Baylis-Hillman 反应的新组合合成含 1,2,4-三唑和四唑的 4H-噻喃并[2,3-b]喹啉的新方法。在 MDCK 细胞中评估了目标化合物对甲型流感/波多黎各/8/34 病毒的细胞毒性和抗病毒活性。这些化合物显示出低毒性,并且一些显示出中等的抗病毒活性。分子对接将 M2 通道和聚合酶碱性蛋白 2 确定为潜在靶点。我们观察到,噻喃并[2,3-b]喹啉的抗病毒活性显着受到四唑环内取代基的性质和位置以及喹啉苯部分内取代基的影响。这些发现有助于在吡喃并[2,3-b]喹啉衍生物中进一步寻找抗甲型流感病毒的新抗病毒药物。
