Provided are: a radiolabeled drug, which is efficiently accumulated in a target and has high in vivo stability; and diagnosis and treatment each using the radiolabeled drug. Specifically provided are: a radiolabeled drug showing increased accumulation in a target site, which comprises a complex composed of a ligand that is bound to a compound capable of binding to a target molecule and forms a polycoordinated complex with a metal (e.g., technetium or rhenium) and a radionuclide of the metal; the radiolabeled drug for diagnosis or treatment; a ligand for preparing the radiolabeled drug; a kit that comprises a drug comprising the ligand and a drug comprising a radionuclide of a metal, as separate package units; and a method of increasing accumulation of a radiolabeled drug in a target site, comprising using the above-mentioned radiolabeled drug.
本发明提供了:一种放射性标记药物,该药物可在靶点中有效积累,并具有较高的体内稳定性;以及使用该放射性标记药物的诊断和治疗方法。具体地说,提供了一种放射性标记药物,该药物在靶位点的蓄积量增加,它包括由配体组成的复合物,配体与能与靶分子结合的化合物结合,并与金属(如锝或铼)形成多配位复合物、用于诊断或治疗的放射性标记药物;用于制备放射性标记药物的配体;包括由配体组成的药物和由金属放射性核素组成的药物作为独立包装单元的试剂盒;以及增加放射性标记药物在靶部位蓄积的方法,包括使用上述放射性标记药物。
