Glycosylphosphatidylinositol (GPI) anchors are a group of complex glycolipids that attach extracellular proteins and glycoproteins to the eukaryotic cell outer membrane. To better understand GPI anchorage, it is necessary to have access to homogeneous, structurally defined, and functionalized GPIs and GPI analogs. In this regard, chemical synthesis is necessary, as GPI anchors are rather scarce and
糖基磷脂酰肌醇(GPI)锚是一组复杂的糖脂,可将细胞外蛋白和糖蛋白附着到真核细胞外膜上。为了更好地理解GPI锚定,有必要访问均质,结构定义和功能化的GPI和GPI类似物。在这方面,化学合成是必需的,因为GPI锚在天然来源中相当稀缺且异质。在这项工作中,制备了三种磷酸二甘油酯(GPI)类似物,其磷酸甘油脂与假二糖核心及其荧光素结合物相连,是一种小型工具集,可用于探索脂质成分和碳水化合物端基异构体配置如何影响GPI锚定物的性质。
