6-tetrahydropyrimidine-5-carboxylate derivatives were prepared to evaluate their ability of inhibiting neuraminidase (NA) of influenza A virus. All the compounds were synthesized in good yields starting from aldehyde by using a suitable synthetic strategy, which showed moderate inhibitory activity against influenza A NA. Compound 6g exhibited the strongest inhibitory activity against influenza virus A NA (IC50 = 17
制备了一系列6-氧代-1,4,5,6-四氢嘧啶-5-羧酸酯衍生物,以评估其抑制甲型流感病毒神经氨酸酶(NA)的能力。通过使用合适的合成策略,所有化合物均从醛开始以高收率合成,显示出适度的对A NA流感病毒的抑制活性。化合物6g对流感病毒A NA表现出最强的抑制活性(IC 50 = 17.64μM),这表明嘧啶环可以用作设计新型流感NA抑制剂的核心结构。
