  Synthesis of Urea-Tethered Neoglycoconjugates and Pseudooligosaccharides in Water

  摘要：

  A novel approach to the synthesis of urea glycosides in aqueous media has been explored. Steyermark's glucopyranosyl oxazolidinone was found to be a good synthon for anchoring glucosyl moieties onto amines and thiols. The present method was successfully applied to establish a new route for the synthesis of urea-tethered neoglycoconjugates and pseudooligosaccharides in water.

  photoresponsive supramolecular hydrogelators were discovered, the gel-sol/sol-gel transition of which was pseudo-reversibly induced by light. Studying the optimal hydrogel by NMR spectroscopy and various microscopy techniques showed that the trans-cis photoisomerization of the double bond of the fumaric amide unit effectively caused assembly or disassembly of the self-assembled supramolecular fibers to yield

  在以富马酰胺为反式顺式光开关模块的基于糖脂的水凝剂的聚焦库中，发现了数种新的光响应性超分子水凝剂，其凝胶-溶胶/溶胶-凝胶转变是光可逆地诱导的。通过NMR光谱学和各种显微镜技术研究了最佳水凝胶，结果表明富马酰胺单元双键的反式顺式光异构化有效地导致了自组装超分子纤维的组装或分解，从而分别产生了宏观水凝胶或相应的溶胶。 。超分子纤维的缠结产生了纳米网，根据共聚焦激光扫描显微镜观察，超分子水凝胶中嵌入的纳米珠的尺寸依赖性布朗运动，其空隙空间大致估计为250 nm。清楚地表明，此类纳米网成为捕获亚微米至微米大小底物（如珠子或细菌）的物理障碍。通过利用超分子纳米网的光响应特性，我们成功地关闭/打开了超分子水凝胶中的细菌束缚和串珠拴系的F（1）-ATPase（一种生物分子运动蛋白）的旋转运动。此外，通过使用光刻技术，成功地进行了凝胶-溶胶光图案化以在凝胶基质内产生溶胶点。制成的凝胶-溶胶模式不仅可以在

  New classes of sugar derivatives of the antibacterial drug norfloxacin (1) were synthesized by substituting the N-4' of the piperazinyl moiety of the molecule. Direct coupling with gluco- and galactopyranosyl units afforded glycosylamines 2-5. Introduction of urea or thiourea linkage between glycosyl and norfloxacin units was produced with the corresponding glycosyl isocyanates or isothiocyanates. For the synthesis of unprotected sugar urea compounds, a new approach was applied by using 1,2-N, O-carbonyl-beta-D-glycopyranoses. Hydrazinocarbonyl-methyl- and -propyl spacers also were found appropriate for linking norfloxacin with sugar units.

  The present application discloses novel glycoproteins and a related glycosylcarbamoylation methodology suitable for the preparation of glycopeptides (in particular glycoproteins and glycosylated cells), as well as the use of such glycoproteins in medicine, e.g. as pharmaceuticals and diagnostics or in diagnostic kits. The method for the preparation of a carbohydrate-peptide conjugate comprises reacting a cyclic carbamate (1) (wherein R 3 and R 4 are hydroxyl, acetamido, or a carbohydrate moiety; and R 5 is hydrogen, methyl, hydroxymethyl, acetamidomethyl, carboxyl, or X—(CH 2 ) r —, wherein X is a carbohydrate moiety and r is an integer selected from 0, 1, 2 and 3) with a peptide comprising at least one primary amino group.
