The potential applications of N-hexyl-4-aminobutyl glycosides in the mass spectrometric investigation of glycan structure and in the investigation of glycan functions were studied. Under collision-induced dissociation (CID) conditions, sodiated glycosides carrying N-hexyl-4-aminobutyl groups effectively produced a hemiacetal species (C-ions), which is important in mass-spectrometry-based structural investigation. The usefulness of N-hexyl-4-aminobutyl glycosides in biological analysis was also confirmed by obtaining a binding constant for the binding of dipyrrometheneboron difluoride C3-labeled N-hexyl-4-aminobutyl β-lactoside with an Erythrina cristagalli lectin, and by visualizing cellular organelles using a more hydrophobic BODIPY-labeled compound.
研究了 N-己基-4-氨基丁基糖苷在聚糖结构的质谱研究和聚糖功能研究中的潜在应用。在碰撞诱导解离 (CID) 条件下,带有 N-己基-4-氨基丁基的钠化糖苷有效地产生半缩醛物质(C 离子),这对于基于质谱的结构研究非常重要。通过获得二氟化二吡咯亚甲基硼 C3 标记的 N-己基-4-氨基丁基 β-乳糖苷与刺桐凝集素结合的结合常数,并通过可视化,也证实了 N-己基-4-氨基丁基糖苷在生物分析中的有用性。使用更具疏水性的 BODIPY 标记化合物的细胞器。
