Sequence selective dual-emission detection of (i, i + 1) bis-phosphorylated peptide using diazastilbene-type Zn(II)-Dpa chemosensor

Yoshiyuki Ishida, Masa-aki Inoue, Tomonori Inoue, Akio Ojida and Itaru Hamachi

This paper describes a new fluorescent chemosensor for phosphorylated peptide, which comprises a rigid trans-4,4-diazastilbene and two Zn(II)-Dpa (2,2-dipicolylamine) units; this chemosensor sequence-selectively binds to a (i, i + 1) bis-phosphorylated peptide and displays a dual-emission fluorescence change.
