chelating ligand represented by the following chemical formula (1).
New arylpiperazine derivatives according to the present invention have no problem of amide hydrolysis in metabolism and have a high affinity for serotonin receptors, and can be labeled with an optimum radionuclide of technetium, thereby being usefully applied for monitoring neurodegenerative diseases or neurological diseases of a mammal.
