Automated glycan assembly (AGA) was employed to prepare the core structure of AM from MTB, containing α-(1,6)-Man, α-(1,5)-Ara, and α-(1,2)-Man linkages. The introduction of a capping step after each glycosylation and further optimized reaction conditions allowed for the synthesis of a series of oligosaccharides, ranging from hexa- to branched dodecasaccharides.

甘露聚糖(
AM)
多糖是结核分枝杆菌(
MTB)感染的临床
生物标志物,因为它们在与宿主细胞相互作用和干扰巨噬细胞活化中发挥作用。定义的
AM寡糖的集合可以帮助提高对这些
多糖的了解,并开发新的治疗和诊断剂。使用自动聚糖组装(AGA)从
MTB制备
AM的核心结构,该结构包含α-(1,6)-Man,α-(1,5)-Ara和α-(1,2)-Man键。在每次糖基化和进一步优化的反应条件后引入封端步骤,可以合成一系列低聚糖,范围从六糖到支链十二糖。
