Outline of Final Research Achievements

In this study, we constructed fluorinated lipid molecular chains with high MRI signals exhibited by fluorine groups and high stability due to fluorous interactions between fluorine groups, and developed highly targeted and safe ovarian cancer-targeted nanocarrier-type 19F-MRI probes. We have synthesized lipid molecules with different numbers of fluorines and found that compounds including 17 fluorine atoms form stable monolayers, and that the stability is improved even in particles filled with ultrasound contrast gas inside. We have also developed fluorinated lipid molecular chains incorporating ovarian cancer-specific ligand molecules. We will formulate the particles and evaluate their efficacy as 19F-MRI probes for ovarian cancer in cell and animal studies.

Academic Significance and Societal Importance of the Research Achievements

卵巣癌は化学療法剤への感受性が高い癌であるが、初期の自覚症状が乏しく、有効な早期診断法は確立されていない。そこで、本研究では、卵巣癌の早期診断薬剤の開発を目指して、フッ素基による高いMRIシグナルとフッ素基同士のフルオラス相互作用よる高い安定性を実現する卵巣癌標的ナノキャリア型19F-MRIプローブの開発研究を行った。研究期間内において、卵巣癌の腫瘍マーカーであるCA125を標的とする高度フッ素化脂質分子の合成に成功し、フルオラス相互作用により安定な単分子膜を形成できることが明らかとなった。今後、19F-MRIプローブとしての製剤化を行い、動物実験等により有用性を明らかにする。
