With a convenient and economical method, two series of 1,3‐thiazine derivatives 1 and 2 were synthesized, and their neuraminidase (NA) inhibitory activities were evaluated. The pharmacological results showed that most of the compounds have potent NA inhibitory activity. Especially, 1g exhibited the best activity against influenza virus A (H1N1) NA (IC50 = 29.06 µg/mL), and its crystal structure was
通过一种方便经济的方法,合成了两个系列的 1,3-噻嗪衍生物 1 和 2,并评估了它们的神经氨酸酶 (NA) 抑制活性。药理结果表明,大多数化合物具有有效的NA抑制活性。特别是,1g 对甲型流感病毒(H1N1)NA 表现出最佳活性(IC50 = 29.06 µg/mL),其晶体结构由单晶 X 射线衍射确定。初步生物学分析表明,1,3-噻嗪可用作设计新型流感NA抑制剂的核心结构。
