    摘要:
    糖基化可以对肽的性质和功能产生多方面的影响,并且在与靶分子相互作用或结合中起关键作用。在此,根据先前报道的大环糖肽合成方法,合成了两个系列的酪氨酸A糖基化衍生物(1a-f和2a-f),并对其抗菌活性进行了评估,以进一步研究其结构和活性关系(SAR)。生物学研究表明,合成的糖基化衍生物对耐甲氧西林的金黄色葡萄球菌和耐万古霉素的肠球菌具有良好的抗菌活性。。SAR研究基于各种聚糖和键联来增强生化特性,从而鉴定出几种有效的抗生素,例如1f,其治疗指数比酪氨酸A大为改善。版权所有©2015欧洲肽协会和John Wiley&Sons ,Ltd.

    通过铜(I)介导的 1,3-偶极环加成(“点击”反应)与 D-葡萄糖、D-半乳糖、D-甘露糖、D-木糖功能化的叠氮化物制备了一系列含有糖部分的吡啶基三唑配体。以及 D-麦芽糖残基和 2-乙炔基吡啶作为炔烃。用Re(CO)5Cl处理过乙酰化糖残基及其水溶性脱保护衍生物,得到相应的单核铼(I)羰基配合物[LRe(CO)3Cl]。为了进行比较,制备了一种带有叔丁基苄基残基而不是糖部分的 ReI 复合物以及两种衍生自含有两个吡啶基三唑单元的支化配体的双核铼复合物。配体和配合物的结构和完整性通过核磁共振、红外、紫外/可见光和荧光光谱、质谱、并通过元素分析。通过吡啶基氮原子和三唑氮原子之一发生金属离子的配位。用过量组氨酸处理后,Rel 复合物仅能稳定 2.5 小时。在较长时间(24 小时)后,通过 HPLC 测量检测到配体交换。相比之下,发现用 99mTc 标记的复合物对过量的组氨酸可稳定长达 24 小时。使用

    Small and air-stable gold nanoparticles (AuNPs) were stabilized in water by a xyloside ligand prepared via click chemistry from d-xylose. During this work, the coordination triazole chemistry with Au(III) ions was explored. AuNPs were characterized by UV-Vis spectroscopy, DLS and TEM. Their catalytic efficiency for the reduction of 4-nitrophenol was evaluated.

  • Carbohydrate Microarrays for Assaying Galactosyltransferase Activity
    作者:Sungjin Park、Injae Shin
    DOI:10.1021/ol070250l
    日期:2007.4.1
    Carbohydrate microarrays have been used recently for the rapid analysis of glycan-protein or glycan-cell interactions and for the detection of pathogens. As a demonstration of its significance and versatility, the microarray technology has been applied in this effort to assay glycosyltransferase activities. In addition, carbohydrate microarray based methods have been employed to quantitatively determine binding affinities between lectins and carbohydrates.
  • “Click” Glycodendrimers Containing 27, 81, and 243 Modified Xylopyranoside Termini
    作者:Jérémy Camponovo、Caroline Hadad、Jaime Ruiz、Eric Cloutet、Sylvain Gatard、Jacques Muzart、Sandrine Bouquillon、Didier Astruc
    DOI:10.1021/jo900554b
    日期:2009.7.17
    A series of large glycodendrimers containing 27, 81, and 243 terminal modified xylose branches from the first (G(1)-27) to the third generation (G(3)-243) were synthesized from 2'-azidoethyl 2,3,4-tri-O-acetyl-beta-D-xylopyranoside and alkynyl-terminated dendrimers by "click" chemistry that is confirmed to be an excellent method to obtain large glyco-dendtimers exemplified by the use of modified xylose. The dendrimers were first characterized by H-1 NMR, C-13H-1} NMR, elemental analysis, and IR spectroscopy. The size progression in the series was also demonstrated using both DOSY NMR and size exclusion chromatography (SEC), the latter technique showing the good polydispersity of all the dendrimers. The size measured by dynamic light scattering (DLS) for the dendrimer G(3)-243 is close to that obtained by the DOSY NMR method.
