In spired by the important role of amide groups of anti-influenza drugs oseltamivir, zanamivir and peramivir in bioactivity, a series of novel amides modified rupestonic acid derivatives were designed and synthesized. The absolute configuration of critical intermediate bearing chloride with newly formed stereocenter was confirmed by X-ray crystallographic analysis. And all new compounds were evaluated

奥司他韦,
扎那米韦和
帕拉米韦酰胺基在
生物活性中的重要作用的启发,设计并合成了一系列新型的酰胺修饰的鼠李
酮酸衍
生物。通过X射线晶体学分析证实了具有新形成的立体中心的关键中间体
氯化物的绝对构型。并评估了所有新化合物对甲型流感(H1N1和
H3N2)和乙型流感病毒的体外抑制活性。
生物测定结果表明,5h 将4-
氟苄基磺酰基修饰为rupestonate甲酯的2位显示出对甲型流感病毒(H1N1和 )的最高活性,甚至比参考药物oseltamivir和
利巴韦林(RVB)更强,并可能被推荐作为进一步开发新的
铅化合物抗流感试剂。
