Abstract

With the concerning rise in antibiotic-resistant infections, novel treatment options against pathogens are urgently sought. Several recent studies have identified mucin O-glycan mixtures as potent down-regulators of virulence-related gene expression in diverse pathogens. As individual mucin glycans cannot be isolated in sufficient purity and quantity for biological evaluation of discrete structures, we have developed an optimized synthetic approach to generate a small library of mucin glycans which were identified as most likely to display activity. The glycans have been prepared in sufficient quantity to assess biological function, studies of which are currently ongoing.

摘要

随着抗生素耐药性感染的令人担忧的增加,人们迫切需要寻找针对病原体的新治疗方法。最近的几项研究已经确定粘蛋白 O-聚糖混合物是多种病原体中与毒力相关基因表达的有效下调因子。由于无法分离出足够纯度和数量的单个粘蛋白聚糖来对离散结构进行生物评估,我们开发了一种优化的合成方法来生成一小部分粘蛋白聚糖文库,这些文库被认为最有可能显示出活性。已经制备了足够数量的聚糖来评估其生物功能,目前正在进行相关研究。
