  摘要：

  3-羟基-4-吡啶酮的糖苷被合成并通过质谱、元素分析、1H和13C核磁共振波谱进行表征，其中一例通过X射线晶体学进行表征。合成并表征了一种新型3-羟基-4-吡啶酮的Cu2+配合物，通过IR和X射线晶体学表明这些化合物具有潜在的螯合有毒金属离子的能力。对选定的糖基化化合物进行的MTT细胞毒性测定显示，在人乳腺癌细胞系中具有相对较低的毒性，IC50 = 570 ± 90 μM。吡啶酮糖苷可以通过广特异性β-糖苷酶，即根癌农杆菌β-葡糖苷酶分解，对于一种化合物，kcat和Km分别为19.8 s−1和1.52 mM。测定了自由吡啶酮的Trolox等效抗氧化能力（TEAC）值，表明这些化合物具有良好的抗氧化性能。非糖基化的吡啶酮配体可以解溶锌和铜的金属-Aβ1-40聚集体。

  A sequential one-pot per-O-acetylation–S-/O-glycosidation of native mono and disaccharides under solvent free conditions using 0.5 mole% of Mg(OTf)2 as a non-hygroscopic, recyclable catalyst is reported. Regioselective 4,6-O-arylidenation of glycosides and thioglycosides with benzaldehyde or p-methoxybenzaldehyde dimethyl acetal is catalyzed by 10 mole% of Mg(OTf)2 to produce the corresponding 4,6-O-arylidenated

  has superior fluorescence stability and quantum efficiency as well as solvatofluorochromicity than the one in the liquid phase. In addition, the phenomenon of fluorescence turn-on occurs when the gel is formed in protic solvents. These features have been applied to perform multicolor fluorescence patterning, chemical vapor sensing, data encryption and decryption, and real-time fluorescence cell imaging

  溶剂化荧光变色是对有机染料荧光颜色的溶剂化作用，是一种通常仅限于流体溶液的特性。我们在此通过使用有机凝胶剂 ( 1 -SG) 展示了固态溶剂化荧光变色的概念，该有机凝胶剂由溶剂化荧光变色绿色荧光蛋白 (GFP) 发色团 ( 1 ) 和糖凝胶剂 (SG) 组成。虽然1-SG 可以位于 SG 凝胶的液相或纤维状固体基质中，我们的结果表明，在固体基质中但靠近液体界面的那一种比在 SG 凝胶中的具有更好的荧光稳定性和量子效率以及溶剂化荧光色度。液相。此外，凝胶在质子溶剂中形成时会出现荧光开启现象。这些功能已被应用于执行多色荧光图案、化学气相传感、数据加密和解密以及实时荧光细胞成像。

  The present invention generally relates to materials and methods for exploiting glycosyltransferase reversibility for nucleotide diphosphate (NDP) sugar synthesis. The present invention provides engineered glycosyltransferase enzymes characterized by improved reaction reversibility and expanded sugar donor specificity as compared to corresponding non-mutated glycosyltransferase enzymes. Such reagents provide advantageous routes to NDP sugars for subsequent use in a variety of biomedical applications, including enzymatic and chemo-enzymatic glycorandomization.

  Glycosides and thioglycosides based on monosaccharides in reaction with benzaldehyde dimethylacetal or p-methoxybenzaldehyde dimethyl acetal undergo FeCl3-catalyzed (20 mol %) regioselective 4,6-0-arylidenation producing the corresponding acetals in high yields. FeCl3 also mediates acetalation of glycosides and thioglycosides of cellobiose, maltose, and lactose affording the corresponding 4',6'-O-benzylidene acetals, which were isolated after their acetylation in situ with acetic anhydride and pyridine. The combined yields (two steps) of these final products are also high (61-84%). The procedure is applicable to a wide variety of functional groups including -OBn. (C) 2011 Elsevier Ltd.

  Glycosides of 3-hydroxy-4-pyridinones were synthesized and characterized by mass spectrometry, elemental analysis, 1H and 13C NMR spectroscopy, and in one case by X-ray crystallography. The Cu2+ complex of a novel 3-hydroxy-4-pyridinone was synthesized and characterized by IR and X-ray crystallography, showing the ability of these compounds to chelate potentially toxic metal ions. An MTT cytotoxicity assay of a selected glycosylated compound showed a relatively low toxicity of IC50 = 570 ± 90 μM in a human breast cancer cell line. The pyridinone glycosides could be cleaved by a broad specificity beta-glycosidase, Agrobacterium sp.β-glucosidase, and for one compound kcat and Km were determined to be 19.8 s−1 and 1.52 mM, respectively. Trolox Equivalent Antioxidant Capacity (TEAC) values were determined for the free pyridinones, indicating the good antioxidant properties of these compounds. Metal-Aβ1-40 aggregates with zinc and copper were resolubilized by the non-glycosylated pyridinone ligands.
