  摘要：

  作为进一步进行定量体内研究的先决条件，以进一步探索9-β-D-阿拉伯呋喃糖基腺嘌呤（ara-A）的2'，3'-二-O-乙酰基衍生物对疱疹病毒感染的动力学活性研究了2'，3'-二-O-乙酰基衍生物以及2'-，3'-和5'-单乙酸酯的溶液降解。基于对取代基效应的考虑，发现水溶液水解的速率与等级排序预测一致。然而，初步的体内水解数据与这种预测无关，这表明需要对分子结构对酶催化水解的影响进行更系统的研究。2'-3'-二酯和3'-单酯在水溶液中的重要反应，除了酯水解外，还有3'。---- 5'的酰基迁移。乙腈中的研究证实，2'---- 5'酰基迁移不会在水中发生，而是在有机溶剂中的主要迁移途径。1 H NMR光谱用于研究糖环的构象对溶剂环境的依赖性。尽管确实发生了C（2'）内基和C（3'）内基构象状态之间的平衡变化，但这不是一个戏剧性的变化，不能解释在酰基迁移动力学中观察到的溶剂选择性。

  semipinacol rearrangement that was observed in our laboratory has been applied to the synthesis of several furanose and pyranose derivatives. The process consists of an “orchestrated” [1,2]-hydride shift with departure of a leaving group from the opposite face. Transient formation of a CO group is followed by rapid transfer of a hydride-equivalent from the same face from which the leaving group departed

  human and bovine serum. When the amino group is present on a pyrimidine or purine ring, the dipeptide derivatives are chemically unstable, whereas the tetrapeptide derivatives (i.e., ValProValPro or ValAlaValPro) were much more stable in solution and efficiently converted to the parent drug by the action of DPPIV/CD26. This DPPIV/CD26-directed prodrug technology can be useful to increase solubility of

  在这里，我们探讨基于二肽基肽酶IV（DPPIV / CD26）的前药方法在多种含胺药物中的适用性。已经开发了用于合成二肽和四肽酰胺前药的有效方法，包括胞苷和腺苷核苷的环外氨基官能团的N-酰化方案。我们的研究表明，与存在于芳香环或糖实体上的游离氨基连接的XaaPro二肽是前药，通过纯化的DPPIV / CD26以及可溶性DPPIV / CD26在牛和人血清中的转化，可有效释放母体药物。维达列汀，一种DPPIV / CD26的特异性抑制剂，在纯化的CD26存在下以及在人和牛血清中都能完全阻断前药的水解。当氨基存在于嘧啶或嘌呤环上时，二肽衍生物在化学上是不稳定的，而四肽衍生物（即ValProValPro或ValAlaValPro）在溶液中更稳定，并通过DPPIV /的作用有效地转化为母体药物CD26。这种DPPIV / CD26导向的前药技术可用于增加母体药物分子的溶解度和/或提供更好的制剂性能。
• Reaction intermediate analogues as bisubstrate inhibitors of pantothenate synthetase

  The biosynthesis of pantothenate, the core of coenzyme A (CoA), has been considered an attractive target for the development of antimicrobial agents since this pathway is essential in prokaryotes, but absent in mammals. Pantothenate synthetase, encoded by the gene panC, catalyzes the final condensation of pantoic acid with beta-alanine to afford pantothenate via an intermediate pantoyl adenylate. We describe the synthesis and biochemical characterization of five PanC inhibitors that mimic the intermediate pantoyl adenylate. These inhibitors are competitive inhibitors with respect to pantoic acid and possess submicromolar to micromolar inhibition constants. The observed SAR is rationalized through molecular docking studies based on the reported co-crystal structure of 1a with PanC. Finally, whole cell activity is assessed against wild-type Mtb as well as a PanC knockdown strain where PanC is depleted to less than 5% of wild-type levels. (C) 2014 Elsevier Ltd.

  A series of four 9-(2-O-acyl-beta-D-arabinofuranosyl)adenines (5a-d) was synthesized by acylation of 9-[3,5-bis-O-(tert-butyldimethylsilyl)-beta-D-arabinofuranosyl]adenine (2), followed by removal of the tert-butyldimethylsilyl groups under conditions (HOAc, tetra-n-butylammonium fluoride) that prevented acyl migration. The four 2'-O-acyl derivatives 5a-d showed activity in vitro against herpes type 1 viruses [virus ratings = 1.5-2.6; MIC50 = 26-72 micrograms/mL (8.48-21.3 X 10(-5) M)]. The 2'-O-acetyl (5a) and 2'-O-valeryl (5d) derivatives were evaluated in a guinea pig model for genital herpes (herpes type 2); only 5a showed potent activity when given 6 or 24 h postinfection.
• Synthesis of non-hydrolyzable substrate analogs for Asp-tRNAAsn/Glu-tRNAGln amidotransferase

  Non-hydrolyzable substrate analogs for tRNA-dependent amidotransferase, 2'- or 3'-aspartyl or -glutamyl adenosine, were synthesized from adenosine without protection of the adenine base. The hydroxyl groups of adenosine were selectively protected, followed by a series of oxidation/reductions to alter the stereochemistry. DFT calculations revealed the driving forces for the ketone hydrate formation at C-2', but not the C-3' carbon during the oxidation step. Subsequently, triflation and azide replacement yielded azidoadenosines, which were coupled to protected amino acids after deprotection and reduction. After global deprotection, the target substrate analogs were obtained in 2-14% overall yields from adenosine. (C) 2014 Elsevier Ltd. All rights reserved.
