  A series of new carbohydrate-based sulphonamide derivatives were designed, synthesised by employing the so-call 'sugar-tail' approach. The compounds were evaluated in vitro against a panel of CAs. Compared to their parent compound p-sulfamoylbenzoic acid, these compounds showed nearly 100-fold improvement in their binding affinities against hCA II in vitro. All of compounds showed great water solubility

  设计了一系列新的基于碳水化合物的磺酰胺衍生物，通过使用所谓的“糖尾”方法合成。针对一组CA对化合物进行了体外评估。与它们的母体化合物对氨磺酰基苯甲酸相比，这些化合物在体外对hCA II的结合亲和力提高了近100倍。所有化合物均显示出良好的水溶性，并且其化合物水溶液的pH值为7.0。与使用相对较高酸性的多唑胺制剂（pH 5.5）相比，使用局部青光眼药物时，此类特性有利于使它们对眼睛的刺激性大大降低。值得注意的是，化合物7d，7 g，当直接以1％的溶液形式施用到眼中时，7 h证明比青霉酰胺更好地降低了青光眼动物的眼内压（IOP）。通过MTT测定法以所测试的浓度观察到对人角膜上皮细胞的低细胞毒性。

  such compounds would be as scaffolds for the design and synthesis of ligands that will facilitate protein-protein or other receptor-receptor interactions. The affinity of restricted divalent (or higher order) ligands, designed to bind to proteins that recognize carbohydrates which would facilitate clustering and concomitantly promote protein-protein interactions, may be significantly higher than monovalent

  已经通过NMR研究了糖基酰胺的溶液结构。与以Z-抗结构为主的仲芳族糖基酰胺相反，叔芳族糖基酰胺显示出对E-抗结构的强烈偏好。这些种类的分子表现出的结构多样性似乎很重要，因为芳香环或与芳香环相连的基团的方向性可以通过选择在异头中心处具有仲酰胺或叔酰胺来确定，并且可以在设计具有碳水化合物支架的生物活性分子时应予以考虑。还对相关的二价仲和叔糖基酰胺进行了结构分析，这些化合物显示出与单价化合物相似的偏好。受约束的二价化合物具有促进将形成具有受限结构的簇的潜力，因此对于多价配体的作用机理的新颖研究具有潜力。此类化合物的可能应用将用作支架的设计和合成，以促进蛋白质-蛋白质或其他受体-受体相互作用。设计成与识别碳水化合物的蛋白结合的限制性二价（或更高阶）配体的亲和力，其亲和力可能明显高于没有这些特性的单价对应物或多价配体，而后者会促进成簇并同时促进蛋白质-蛋白质相互作用。这可能是开发基于碳水化合物的疗法的一种新方法。

• Synthesis of a glucuronic acid and glucose conjugate library and evaluation of effects on endothelial cell growth

  Compounds that alter endothelial cell growth are of interest in the development of angiogenesis modulators. A structurally diverse series of saccharide derivatives (glycosylamide conjugates) have been synthesized and evaluated for their effects on bovine aortic endothelial cell (BAEC) growth. Heparin-albumin (HA) reduced BAEC growth by 32% at 10 mug/mL and a number of the novel saccharide conjugates from the library were found to mimic the effect of HA as they also inhibit endothelial cell survival under identical conditions. Two thiophene conjugates, thioglucamide (24% inhibition at 35 muM) and a related glucuronide (26% inhibition at 33 muM) were the most potent inhibitors of BAEC growth, as determined using a methylthiazol tetrazoliurn (MTT) assay. The effects of thioglucamide and HA on absolute cell number were also studied using cell counting experiments; thioglucamide (47% after 24 h) was more potent than indicated by the MTT assay and initially reduced the BAEC number to a greater extent than HA (30% after 24 h); however, its actions were over more rapidly than were HA's as cell growth had returned to levels of the control after 72 h where HA still caused 25% inhibition. The binding of the monosaccharide conjugates to fibroblast growth factor (FGF-2) in competition with heparin-alburnin by ELISA was investigated to establish the possible mechanism by which glycoconjugates could alter growth but there was no general correlation between reduction in viable cell population and binding to FGF-2. No glycoconjugate reduced the proliferation of mouse mammary epithelial cells, nor did any alter gross cell morphology, supporting a proposal that the reduction in BAEC survival by monosaccharide conjugates such as thioglucamide is a result of the inhibition of cell proliferation rather than being an induction of cytotoxicity. These studies indicate that cell biological studies to determine the mechanism of action of the simple monosaccharide conjugates may be worthwhile. (C) 2004 Elsevier Ltd. All rights reserved.

  A concise route to novel mimetics of Kdn2en, based on Delta(4)-uronic acids, from D-glucurono-6,3-lactone is presented. Uronic acid-based mimetics in which an aliphatic ether (O-glycoside), a thioether (S-glycoside), or acetamide takes the place of the natural C-6 glycerol sidechain of the sialic acid were synthesized from the key intermediate, methyl 2,3,4-tri-O-acetyl-alpha-D-glucopyranosyluronate bromide.
