  A protecting group-free synthesis of deazathiamine: A step toward inhibitor design

  摘要：

  The discovery of 3-deazathiamine diphosphate (deazaThDP) as a potent inhibitor analog of the cofactor thiamine diphosphate (ThDP) has highlighted the need for an efficient and scalable synthesis of deazaThDP. Such a method would facilitate development of analogs with the ability to inhibit individual ThDP-dependent enzymes selectively. Toward the goal of developing selective inhibitors of the mycobacterial enzyme 2-hydroxy-3-oxoadipate synthase (HOAS), we report an improved synthesis of deazaThDP without use of protecting groups. Tribromo-3-methylthiophene served as a versatile starting material whose selective functionalization permitted access to deazaThDP in five steps, with potential to make other analogs accessible in substantial amounts.

  硫胺素类似物的设计和合成，以研究其与细菌中硫胺素的ECF转运蛋白的结合情况† ‡

  摘要：

  能量耦合因子（ECF）转运蛋白介导细菌中维生素的吸收。鉴于这些ECF转运蛋白不存在于真核细胞中，它们代表了开发新型抗生素的有趣目标。在这里，我们介绍了结合到ThiT的化合物的设计和合成，ThiT是来自乳酸乳球菌的硫胺素的ECF转运蛋白的底物结合域。我们修饰了硫胺嘧啶环的甲基取代基，以评估其对结合亲和力的贡献。我们的结果表明，只要保留疏水取代基，高结合亲和力几乎不变，从而为选择性化合物的设计提供了机会。

  inhibition is to use thiamine/ThDP analogues, which typically feature a neutral aromatic ring in place of the positively charged thiazolium ring of ThDP. While ThDP analogues have aided work in understanding the structural and mechanistic aspects of the enzyme family, at least two key questions regarding the ligand design strategy remain unresolved: 1) which is the best aromatic ring? and 2) how can we achieve

  二磷酸硫胺素 (ThDP) 是维生素 B 1的生物活性形式，是所有生物体细胞代谢过程所需的必需辅酶。尽管各个酶在底物偏好和生化反应方面存在显着差异，但 ThDP 依赖性酶都需要 ThDP 作为催化活性的辅酶。通过化学抑制研究这些酶的作用的一种流行方法是使用硫胺素/ThDP 类似物，其通常具有中性芳香环代替 ThDP 带正电的噻唑鎓环。虽然 ThDP 类似物有助于理解酶家族的结构和机制方面的工作，但有关配体设计策略的至少两个关键问题仍未解决：1）哪个是最好的芳环？2）我们如何才能实现对特定 ThDP 依赖性酶的选择性？在这项工作中，我们合成了这些类似物的衍生物，涵盖了过去十年中使用的所有中心芳环，并对所有化合物作为几种 ThDP 依赖性酶的抑制剂进行了头对头比较。因此，我们建立了中心环的性质与这些 ThDP 竞争性酶抑制剂的抑制谱之间的关系。我们还证明，在中心环上引入 C2 取代基来探索独特

  we present the design and synthesis of compounds that bind to ThiT, the substrate-binding domain of the ECF transporter for thiamine from Lactococcus lactis. We modified the methyl substituent of the pyrimidine ring of thiamine, in order to evaluate its contribution to the binding affinity. Our results indicate that as long as a hydrophobic substituent is maintained, the high binding affinity is almost
