Polyprenols, a type of universal glycan lipid carrier, play important roles for glycan bio-assembly in wide variety of living systems. Chemical synthesis of natural polyisoprenols such as undecaprenol and dolichols, but especially their homologs, could serves as a powerful molecular tool to dissect and define the functions of enzymes involved in glycan biosynthesis. In this paper, we report an efficient
多元醇是一种通用的聚糖脂质载体,在多种生物系统中对聚糖的生物组装起着重要的作用。天然的聚异戊二烯,例如十一碳烯醇和二元醇的化学合成,尤其是它们的同系物,可以作为一种强大的分子工具来分析和确定参与聚糖生物合成的酶的功能。在本文中,我们报告了一种有效且可靠的方法,该方法通过使用关键的双功能(Z,Z)-二异戊二烯结构单元的碱基介导的迭代偶联方法来构建此类疏水分子。还证明了与N-乙酰基-D-葡糖胺(GalNAc)与一组合成的脂质类似物形成聚戊二烯焦磷酸连接的GalNAc(GalNAc-PP-脂质)缀合物的连接。
