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
受到抗流感药物奥司他韦,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H3N2)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。
