Outline of Final Research Achievements

Since cancer drug therapy causes various side effects and places a heavy burden on patients, efficient drug delivery to the affected area and rapid drug release after reaching the affected area are required for early treatment and reduction of side effects. In this study, we have developed new biomolecules and metal-organic structures that disintegrate under reducing conditions, and attempted to apply them as drug delivery carriers.

Academic Significance and Societal Importance of the Research Achievements

がんの投薬治療は様々な副作用をもたらし,患者に大きな負担を与える。早期治療と副作用低減には,患部に薬物を効率的に送達する標的指向性,および到達後に薬物を速やかに放出する放出制御性を有する薬物送達キャリアの開発が求められる。本研究では,これらの要件に加えて,さらに大担持容量,高安定性,および高生分解性を兼ね備えた,グルタチオン応答型の金属有機構造体を創製し,抗がん剤送達キャリアとしての利用を検討した。本研究で創製した送達キャリアは実際にpH応答性と還元応答性を持つことが確認され,次世代の薬物送達キャリアとして利用できることが期待される。
