Described is a modular, general synthetic strategy for the preparation in solution and on a solid support of heparin, heparin-like glycosaminoglycans, glycosaminoglycans and non-natural analogs of each of them. Additionally, the modular strategy provides the basis for the preparation of combinatorial libraries and parallel libraries of defined glycosaminoglycan oligosaccharides. The defined glycosaminoglycan structures may be used in high-throughput screening experiments to identify carbohydrate sequences that regulate a host of recognition and signal-transduction processes. The determination of specific sequences involved in receptor binding holds great promise for the development of molecular tools which will allow modulation of processes underlying viral entry, angiogenesis, kidney diseases and diseases of the central nervous system. Notably, the present invention enables the automated synthesis of glycosaminoglycans in much the same fashion that peptides and oligonucleotides are currently assembled.
描述了一种模块化的通用合成策略,用于在溶液中和固体支撑上制备肝素、类肝素糖胺聚糖、糖胺聚糖以及它们的每一种非天然类似物。此外,该模块化策略为定义的糖胺聚糖寡糖的组合库和平行库的制备提供了基础。定义的糖胺聚糖结构可以用于高通量筛选实验,以识别调节多种识别和信号转导过程的碳水化合物序列。确定参与受体结合的特定序列对于开发分子工具具有巨大的前景,这些工具将允许调节病毒进入、血管生成、肾脏疾病和中枢神经系统疾病等过程。值得注意的是,本发明使得能够以目前组装肽和寡核苷酸的方式自动化合成糖胺聚糖。
