    The present invention relates to the preparation of a synthetic tetrasaccharide, hexasaccharide and octasaccharide representing part of the repeating unit of the Streptococcus pneumoniae type 3 capsular polysaccharide as well as conjugates thereof. Said conjugates are particularly useful for prevention and/or treatment of diseases associated with Streptococcus pneumoniae, and more specifically of diseases associated with Streptococcus pneumoniae type 3. The disclosed synthetic method has the huge advantages over the state of the artsynthetic methods that intermediate products are crystalline, coupling reaction yields are higher, less reaction steps are required and purification of intermediate products is easier.

  • Delineating the conformational flexibility of trisaccharides from NMR spectroscopy experiments and computer simulations

    five trisaccharides via a combination of experimental and computational techniques. Experimental NMR measurements target conformationally sensitive parameters, including J couplings and effective distances around the glycosidic linkages, while the computational simulations apply the well-calibrated additive CHARMM carbohydrate force field in combination with efficient enhanced sampling molecular dynamics
    在单个明确定义的三维结构的背景下,表征溶液中糖类的构象具有挑战性。相反,它们更好地由与其结构多样性和灵活性相关的构象集合表示。在这项研究中,我们通过实验和计算技术的结合描绘了五个三糖的构象异质性。实验NMR测量以构象敏感参数为目标,包括J耦合和糖苷键周围的有效距离,而计算模拟则将经过充分校准的加性CHARMM碳水化合物力场与有效的增强采样分子动力学模拟方法结合使用。基于由二面角定义的离散状态的采样,笛卡尔坐标的均方根差和采样量的范围,进行构象异质性分析。基于糖苷键二面角的构象聚类表明,要重现实验数据,需要考虑样品构象的全部范围,从而强调分子模拟在获得糖类构象特性的原子详细描述中的效用。结果表明,存在不同的构象偏好,这是一级序列和糖苷键类型的函数。与单个糖苷键的异头构型相关的构象集合的显着差异增强了这种变化对碳水化合物的构象性质的影响。目前研究的三糖的结构见解为理解较大的低聚糖所采用的构象范

    Novel methods for the treatment and/or prophylaxis of diseases caused by tissue-adhering bacteria are disclosed. By interacting with periplasmic molecular chaperones it is achieved that the assembly of pili is prevented or inhibited and thereby the infectivity of the bacteria is diminished. Also disclosed are methods for screening for drugs as well as methods for the de novo design of such drugs, methods which rely on novel computer drug modelling methods involving an approximative calculation of binding free energy between macromolecules. Finally, novel pyranosides which are believed to be capable of interacting with periplasmic molecular chaperones are also disclosed.
