Outline of Research at the Start

膜タンパク質上の糖鎖と相互作用する生体分子を検出する技術を開発し、生体機能制御の基盤になる膜タンパク質の動態を理解する。分子サイズが大きい生化学ツールによる特異的標識反応では、膜タンパク質本来の機能が損なわれ、検出精度が低い。また、従来の化学的標識法は生体侵襲性が高い。本研究では、サイズが小さい生体適合触媒による光駆動リレー反応と極小タンパク質タグを複合し、生体侵襲性も低減した標識技術を開発する。

Outline of Final Research Achievements

Cyclooctene catalysts, which have an olefin moiety as a catalytic site, were developed and used for halogenation of tyrosine. In addition, mechanistic studies enabled the development of more active bifunctional cyclooctene catalysts; their protection with photoremovable groups made the catalysts activatable in-situ with visible light. Moreover, biocompatible brominating reagents were developed. They do not occur background reactions but become activated in the presence of the bifunctional cyclooctene catalysts under physiologically favorable conditions. The reactivity of excited states of the reagents was also investigated, and dyes proved useful as a photocatalyst to activate them with visible light for tyrosine modification. These reaction tools facilitate the development of biomolecular labeling methods.

Academic Significance and Societal Importance of the Research Achievements

本研究では、細胞系で生体分子の挙動を解析する技術を開発するために必要な化学反応を実現する触媒や反応剤を開発した。分子レベルで生命現象を理解するための解析技術は病気などの原因を明らかにし、創薬を加速する。また、このような反応制御法は生体分子の機能を操作する技術、すなわち治療技術の創出にも波及することが期待できる。
