葡聚糖是从繁殖到细胞通讯再到感染等生物过程的关键参与者。要揭示多聚糖的作用和显示其功能的潜在分子机制,需要获得系统变化的多聚糖衍生物。为此,糖共聚物(含有侧链碳水化合物的聚合物)已成为有价值的多糖类似物。由于糖共聚物可以很容易地合成,它们的整体形状可以变化,并且可以系统地改变它们,以剖析支撑其活性的结构特征。这篇综述提供了糖共聚物用于影响碳水化合物介导的信号转导的例子。我们的目标是说明这些强大的工具如何揭示碳水化合物介导的信号转导背后的分子机制。
Glycans are key participants in biological processes ranging from reproduction to cellular communication to infection. Revealing glycan roles and the underlying molecular mechanisms by which glycans manifest their function requires access to glycan derivatives that vary systematically. To this end, glycopolymers (polymers bearing pendant carbohydrates) have emerged as valuable glycan analogs. Because glycopolymers can readily be synthesized, their overall shape can be varied, and they can be altered systematically to dissect the structural features that underpin their activities. This review provides examples in which glycopolymers have been used to effect carbohydrate-mediated signal transduction. Our objective is to illustrate how these powerful tools can reveal the molecular mechanisms that underlie carbohydrate-mediated signal transduction.
