  Synthesis of Carbohydrates with an Anomeric Thiol Moiety for Elaboration into Metabolically Stable Thioglycosides

  摘要：

  The synthesis of thioglycosides for use as metabolically stable biological probes is an area of continued interest. This paper describes the synthesis of functionalised carbohydrates which contain an anomeric thio group. During the course of this work we have examined the most viable route into compounds such as the specifically functionalised carbohydrates 36 and 37, and have also investigated the usefulness of disulfides as protecting groups for anomeric thiols.

  Practical synthetic methods to latent disarmed S-2-(2-propylthio)benzyl (SPTB) glycosides for interrupted Pummerer reaction mediated glycosylation have been discovered. Among them, both coupling reaction of PTB-Cl with glycosyl thiols and BF3·OEt2 promoted reaction of peracylated glycosides with PTB-SH produced peracylated SPTB glycosides in large scales and with high efficiency.

  including multidrug resistant strains. It is, however, inactive toward Gram-negative bacteria, for which we are in dire need of new therapies. In this work, 40 auranofin analogues were synthesized by varying the structures of the thiol and phosphine ligands, and their activities were tested against ESKAPE pathogens. The study identified compounds that exhibited bacterial inhibition (MIC) and killing

  FDA批准的关节炎药物金诺芬（Auranofin）最近已被重新用作潜在的抗菌药物。它对许多革兰氏阳性细菌（包括耐多药菌株）表现良好。但是，它对革兰氏阴性细菌没有活性，因此我们急需新疗法。在这项工作中，通过改变硫醇和膦配体的结构合成了40种金诺芬类似物，并测试了它们对ESKAPE病原体的活性。该研究鉴定出的化合物具有比金诺芬高65倍的细菌抑制（MIC）和杀灭（MBC）活性，从而使它们对革兰氏阴性病原体有效。硫醇和膦结构都影响类似物的活性。三甲基膦和三乙基膦配体分别对革兰氏阴性菌和革兰氏阳性菌具有最高的活性。我们的SAR研究表明，巯基配体也非常重要，其结构可以调节AuI复合物对革兰氏阴性细菌和革兰氏阳性细菌的活性。而且，这些类似物具有的哺乳动物细胞毒性与金诺芬相似或更低。

  A one-pot aziridine opening reaction by glycosyl thiols generated in situ from the corresponding anomeric thio-acetates affords thio-glycosides with a pseudo-disaccharide structure and an N-linked tether. The scope of the one-pot aziridine opening reaction was explored on a series of mono- and disaccharides, creating a class of pseudo-glycosidic compounds with potential for further functionalization
