  Synthesis, CI-MS Analyses and Preliminary Biological Evaluation of a Novel Library of Hydrophobic Persulfide-Spacers α-Alkyl Glycosides

  摘要：

  We report the synthesis of novel polyether-based polyols derived from simple glycosides that bear sulfur spacers in the attempt to potentially provide new antibiotics. The CI-MS demonstrated the stepwise and successive fission of the sulfide-spacer groups; however, it does not distinguish between the alditols having different arrangement of O(CH2)(3)-S(CH2)(2)OH groups. The investigated compounds exhibited antimicrobial activities against Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and antifungal activities against Candida albicans at a concentration of 1 mg / ml in DMF.

  this work, a buffer/ethyl acetate ratio of 5:3 was identified to be the optimal solvent system, allowing the use of SP in biphasic systems. Careful optimization of the reaction conditions enabled the synthesis of a range of α-d-glucosides, such as cinnamyl α-d-glucopyranoside, geranyl α-d-glucopyranoside, 2-O-α-d-glucopyranosyl pyrogallol, and series of alkyl gallyl 4-O-α-d-glucopyranosides. The usefulness

  由于其广泛的受体特异性，蔗糖磷酸化酶（SP）已被用于将葡萄糖转移至多种受体分子。不幸的是，SP对这些受体的亲和力低（K m > 1 M）通常促使添加助溶剂，助溶剂通常不能溶解足够的底物或逐渐引起酶抑制和变性。在这项工作中，确定缓冲液/乙酸乙酯的比例为5：3是最佳溶剂系统，从而允许在双相系统中使用SP。的反应条件的仔细优化启用的范围α-的合成d -glucosides，如肉桂α- d吡喃葡萄糖苷，香叶基α- d吡喃葡萄糖苷，2- ö-α- d吡喃葡萄糖基邻苯三酚，和烷基gallyl 4-系列ö -α- d -glucopyranosides。通过在辅助溶剂和双相反应系统中比较邻苯三酚的葡萄糖基化进一步说明了双相催化的有用性。前者的受体收率仅达到17.4％，而使用双相催化时，大约60％的初始邻苯三酚会转化。
