  Synthetic Strategies to 9-Substituted 8-Oxoadenines

  摘要：

  Three synthetic routes to 9-substituted 8-oxoadenines have been studied: bromination of adenine followed by N-9-alkylation/arylation and finally hydrolysis; bromination of adenine, hydrolysis, and N-functionalization as the last step; and N-9-alkylation of adenine, halogenation, and finally hydrolysis. As long as the N-9-functional group is compatible with conditions required for introduction of the halogen, the latter strategy was the most efficient. Also, a strategy starting from 5-amino-4,6-dichloropyrimidine was found to be a very good alternative for synthesis of 9-substituted 8-oxoadenines.

• The Suzuki-Miyaura Cross-Coupling Reactionsof 2-, 6- or 8-Halopurines with Boronic Acids Leading to 2-, 6- or 8-Aryl- and -Alkenylpurine Derivatives

  The Suzuki-Miyaura cross-coupling reactions of 9-benzyl-6-chloropurine, 9- or 3-benzyl-8-bromoadenine and 2,6-dihalopurines with boronic acids gave the corresponding 6-, 8- or 2-aryl- or -alkenylpurines in good yields. Anhydrous conditions in toluene were superior for coupling of electron-rich boronic acids, while aqueous DME was used for electron-poor arylboronic acids as well as for alkenylboronic acids. A good regioselectivity was observed for the coupling of 2,6-dihalopurines: 9-benzyl-2,6-dichloropurine reacted with one equivalent of phenyl boronic acid to give 9-benzyl-2-chloro-6-phenylpurine, while an analogous reaction of 9-benzyl-6-chloro-2-iodopurine gave selectively 9-benzyl-6-chloro-2-phenylpurine.

  Inhibition of FBPase is considered a promising way to reduce hepatic gluconeogenesis and therefore could be a potential approach to treat type 2 diabetes. Herein we report the discovery of a series of purine phosphonic acids as AMP mimics targeting the AMP site of FBPase, which was achieved using a structure-guided drug design approach. These non-nucleotide purine analogues inhibit FBPase in a similar

  抑制FBPase被认为是减少肝脏糖异生的有前途的方法，因此可能是治疗2型糖尿病的潜在方法。本文中，我们报道了一系列嘌呤膦酸的发现，它们是针对FBPase AMP位点的AMP模拟物，这是使用结构指导药物设计方法实现的。这些非核苷酸嘌呤类似物以与AMP相似的方式和相似的效力抑制FBPase。更重要的是，几种嘌呤类似物表现出有效的细胞和体内降糖活性，从而获得了抑制FBPase作为药物发现靶标的概念证明。例如，就FBPase抑制而言，化合物4.11和4.13与AMP等价。此外，化合物4.11 抑制原代大鼠肝细胞中的葡萄糖生成，并显着降低禁食大鼠的血糖水平。
