A series of acylhydrazone derivatives (4a–4s) were synthesized via microwave irradiation with short reaction time and good yields. The crystal structure of compound 4j was further determined by single-crystal X-ray diffraction. All of the derivatives were evaluated in vitro for influenza neuraminidase inhibitory activities. Among them, compounds 4l and 4n showed the most potent activity with IC50 values
通过微波辐照合成了一系列hydr derivatives衍生物(4a - 4s),反应时间短,产率高。通过单晶X射线衍射进一步确定化合物4j的晶体结构。在体外评估所有衍生物的流感神经氨酸酶抑制活性。其中,化合物4l和4n表现出最强的活性,IC 50值分别为59.86和49.97μM。进行了分子对接以研究蛋白质与化合物4n之间的相互作用。对接结果揭示了标题化合物的潜在双位点结合模型(“ 430腔-Linker-SA腔”模型),这为新型流感神经氨酸酶抑制剂的设计提供了新思路。
