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.
本发明涉及用于成像5-羟色胺受体的Tc标记的芳基哌嗪衍生物,更具体地说,涉及与MAMA-二硫化物、N2S2或二甲基-N2S2螯合配体偶联的芳基哌嗪衍生物,其化学式如下(1)。根据本发明的新芳基哌嗪衍生物在代谢中没有酰胺水解问题,对5-羟色胺受体具有高亲和力,并且可以与锝的最佳放射性核素标记,因此可以用于监测哺乳动物的神经退行性疾病或神经系统疾病,具有实用价值。
