4-Formylbenzene diazonium hexafluorophosphate (FBDP) is a novel bench-stable crystalline diazonium salt that reacts selectively with tyrosine to install a bioorthogonal aldehyde functionality. Model studies with N-acyl-tyrosine methylamide allowed us to identify conditions optimal for tyrosine ligation reactions with small peptides and proteins. FBDP-based conjugation was used for the facile introduction of small molecule tags, poly(ethylene glycol) chains (PEGylation), and functional small molecules onto model proteins and to label the surface of living cells.
4-甲酰基苯重氮六氟磷酸盐（FBDP）是一种新型的、稳定的晶体重氮盐，它能选择性地与酪氨酸反应，引入一个生物正交的醛基官能团。通过对 N-酰基-酪氨酸甲酯的模型研究，我们确定了与小肽和蛋白质进行酪氨酸连接反应的最佳条件。基于 FBDP 的偶联反应可用于将小分子标签、聚乙二醇（PEGylation）链和功能小分子轻松地引入到模型蛋白中，并对活细胞的表面进行标记。
