摘要
The reactions of four different N-(O,O'-diisopropyl) phosphoamino acids (DIPP-aa), such as N-phosphoryl-L-α-alanine (DIPP- L-α-Ala), N-phosphoryl-D-α-alanine (DIPP-D-α-A1a), N-phosphoryl-β-alanine (DIPP-β-A1a) and N-phosphoryl-γ-amino butyric acid (DIPP-γ-Aba), and four nucleosides, adenosine (A), guanosine (G), cytidine (C) and uridine (U), were studied by electrospray ionization tandem mass spectrometry (ESI-MS/MS) and HPLC/ESI-MS. DIPP-L-α-A1a and DIPP-D-α-A1a produced the same phosphorylated nucleosides, dinucleotides and phosphoroligopeptide. However, DIPP-β-A1a and DIPP-γ-Aba gave no relevant products.
