There are provided a novel compound which captures a multisite phosphorylated peptide or protein specifically to a phosphorylation site and a method for detecting a multisite phosphorylated peptide or protein using the same. In particular, there are provided a compound which specifically detects an excessively phosphorylated tau protein observed in the brain affected by Alzheimer's disease and a method for diagnosing Alzheimer's disease in vitro or in vivo using the compound. By bringing a metal complex compound having two dipicolylamine (Dpa) moieties and a spacer including a chromogenic or luminescent functional group or atom group into contact with a multisite phosphorylated peptide or protein, the compound recognizes the distance between phosphate groups and specifically binds to the peptide or the protein, and a multisite phosphorylated peptide or protein or a kinase activity is optically detected by measuring the change, or a multisite phosphorylated peptide or protein or kinase activity is imaged by an optical imaging method applying the change in the luminescence.

Fluorescent BODIPY-Based Zn(II) Complex as a Molecular Probe for Selective Detection of Neurofibrillary Tangles in the Brains of Alzheimer’s Disease Patients
developed a new fluorescent binuclear Zn(II) complex for the detection of neurofibrillary tangles (NFTs) of hyperphosphorylated tau proteins, a representative hallmark of Alzheimer'sdisease (AD). The probe 1 incorporates a fluorescent BODIPY unit and two Zn(II)-2,2'-dipicolylamine (Dpa) complexes as a binding site for phosphorylated amino acid residues. Using fluorescence titration to evaluate the binding
