  N6-乙酰基-2'，3'，5'-三-O-乙酰腺苷；区域选择性N6-烷基化的便捷“缺失”底物

  摘要：

  在咪唑存在下，在室温下用甲醇对五乙酰基腺苷2进行选择性的N-脱乙酰基化反应，建立了一种简单有效的N 6-乙酰基2'，3'，5'- tri - O-乙酰腺苷（1）路线。 。利用2和1的粗混合物，通过腺苷与乙酸酐在吡啶中在升高的温度下反应制备的混合物，详细说明了1的制备合成。从腺苷开始，总产率为1，为80-85％。结果表明1是选择性N 6的便捷底物-烷基化。该研究揭示了在1与活化的烷基卤化物的碱促进反应和1与醇的光延反应中相同的区域选择性。制备了一系列的N 6-烷基腺苷5a - f。通过使用核苷磷酸化酶和碱性磷酸酶的组合对母体核苷衍生物5b，d，e进行酶促转化来制备细胞分裂素6b，d，e。 细胞分裂素-腺苷衍生物-N 6-烷基化-区域选择性-Mitsunobu反应-核苷磷酸化酶

  A series of N⁶-adenosine derivatives were synthesized by alkylation of N⁶-acetyl-2′,3′,5′-tri-O-acetyladenosine (1) with alkyl halides and alcohols. It was shown that propargyl derivative 2a is a good substrate for copper(I) catalyzed Huisgen [3+2] cycloaddition with azides. This click-reaction can be used for preparation of the libraries of 1,2,3-triazolyl modified adenosines. Biological activities of N⁶-adenosines were studied in two plant and six human cancer cell assays. The remarkable parallel between cytokinin and cytotoxic activities was found. The most cytokinin active compounds 3c–3e at the same time appeared to be the most potent cytotoxic agents.

  一系列的N6-腺苷衍生物通过烷基卤化物和醇对N6-乙酰-2'，3'，5'-三-O-乙酰基腺苷（1）进行烷基化合成。结果表明，丙炔基衍生物2a是铜（I）催化的Huisgen [3+2]环加成与叠氮化物反应的良好底物。此点击反应可用于制备1,2,3-三唑基修饰的腺苷库。在两种植物和六种人类癌细胞测试中研究了N6-腺苷的生物活性。发现细胞分裂素和细胞毒性活性之间存在显著的平行关系。同时，最具细胞分裂素活性的化合物3c-3e也被证明是最有效的细胞毒性剂。

  In this study, we demonstrate that N-6-isopentenyladenosine, which essentially is a plant cytokinin-like compound, exerts a potent and selective antiviral effect on the replication of human enterovirus 71 with an EC50 of 1.0 +/- 0.2 mu M and a selectivity index (SI) of 5.7. The synthesis of analogs with modification of the N-6-position did not result in a lower EC50 value. However, in particular with the synthesis of N6-(5hexene-2-yne-1-yl)adenosine (EC50 = 43 +/- 1.5 mu M), the selectivity index was significantly increased: because of a reduction in the adverse effect of this compound on the host cells, an SI > 101 could be calculated. With this study, we for the first time provide proof that a compound class that is based on the plant cytokinin skeleton offers an interesting starting point for the development of novel antivirals against mammalian viruses, in the present context in particular against enterovirus 71.
