Description
技术领域
本发明属化合物的合成方法以及应用,主要涉及哌嗪酮并羟基吡啶酮-5-羧基类化合物及其制备方法和应用。
背景技术
哌嗪酮并羟基吡啶酮类化合物是药物设计常用母核之一,具有很好的金属螯合特性,如ViiV Healthcare公司研究开发的度鲁特韦是一种HIV整合酶抑制剂,主要通过分子结构中的哌嗪酮并羟基吡啶酮母核上的羰基以及羟基基团来螯合HIV整合酶活性位点中的镁离子,进而抑制HIV病毒嵌入宿主细胞DNA,该药物在2013年被FDA批准上市。流感病毒主要通过Cap-snatching机制来进行子代病毒RNA的复制,其中帽端依赖性内切酶是金属依赖性的核酸内切酶,能够将宿主细胞内的RNA切割成核酸片段供子代病毒RNA的合成使用,通过抑制帽端依赖性核酸内切酶可以起到抗流感的作用,代表性流感病毒抑制剂S-033188也含有哌嗪酮并羟基吡啶酮类的母核,因此这类母核的合成非常重要。但是这类母核的合成需要多步反应,例如S-033188的合成,是以3-苄氧基-4-氧代-4H-吡喃-2-羧酸为起始原料,经十三步反应合成最终的产物,这个从头合成的方法不仅耗时长、试剂昂贵,而且经过这么多步反应合成最终产物使得产物的收率极低。
