Outline of Final Research Achievements

In PET imaging and therapy of the cancer using Cu-64 and Cu-67 ions without any labeling process, physiological accumulation of Cu-64,67 in liver needs to be reduced. In the present study, we searched for chelating agents by transchelation of Cu-64,67 from plasma proteins as an index, and a simultaneous use of them efficiently reduced the physiological accumulation in the liver.

Academic Significance and Societal Importance of the Research Achievements

本研究で得られた成果により、サイクロトロンで製造したCu-64およびCu-67イオンを、分子標的薬である高価な抗体やペプチドと化学合成する必要もなく、低コストかつ簡便迅速に利用できる。さらに、併用薬剤により代謝による生理的集積を抑え込み、特異的にがんへCu-64,67を集積させることで、無用な被ばくを生じさせずにより高精度な診断と治療が可能となる。
