Outline of Research at the Start

生体内の水輸送チャネルであるアクアポリンは、その疎水性内壁によって高速水輸送を実現している。本研究では、複数回膜貫通型人工ナノチャネル分子に多数のフッ素原子を導入することで、フッ素化合物の特徴である超疎水性を有したフルオラスナノチャネルを開発し、天然のアクアポリンをも上回る選択的超高速水輸送の実現を目指す。

Outline of Final Research Achievements

In this research, we have developed a novel fluorinated multiblock amphiphile that mimicked the structures and functions of ion channel proteins found in nature. We found that this molecule can be incorporated into the lipid bilayer membranes and self-assemble to form a supramolecular ion channel with anisotropic dual-stimuli-responsiveness.

Academic Significance and Societal Importance of the Research Achievements

我々の身体を構成する細胞の表面には、多様な刺激に応答してイオンを輸送するイオンチャネルタンパク質が存在し、生命の維持に欠かせない様々な役割を担っている。一方、イオンチャネルタンパク質に異常が生じることでイオンチャネル病と呼ばれる様々な難治性疾患が生じることも知られている。そこで、本研究で開発した人工イオンチャネルを利用し、異常が生じたイオンチャネルの機能を代替することで、新たな治療法の確立に繋がることが期待される。
