Biotinylated peptides often have low solubility in water. In this Letter, we describe a new method to synthesize a biotinylating reagent for water-solubilizing hydrophobic peptides. The biotinyl-6-aminohexanoic derivatives prepared contain a hydrophilic 3,6,9-trioxaundecanedioic acid linker moiety between the biotin and the peptide to improve the water solubility, and also to function as a spacer.

生物素化的肽通常在水中具有低溶解度。在这封信中,我们描述了一种合成用于水溶疏水肽的生物素化试剂的新方法。制备的生物素-6-氨基己酸衍生物在生物素和肽之间包含亲水的3,6,9-三氧杂十二烷二酸接头部分,以改善水溶性,并起间隔基的作用。合成了3,6,9-三氧杂十二烷二酸的单酯化衍生物,并将Fmoc保护的乙二胺用于连接生物素的羧基。在对包含生物素-6-氨基己酸或3,6,9-三氧杂十二烷二酸衍生物的化合物进行的比较分析中,也证明了这种新的生物素-肽结合物的亲水性。
