Outline of Final Research Achievements

A multi-step structure-based virtual screening (SBVS) targeting the outer surface region of D-amino acid oxidase (DAO) was conducted, narrowing down compounds from a library. The interaction information of existing DAO inhibitors was not used as a prerequisite. After the final SBVS step and selection by consensus ranking, five compounds were examined by in vitro experiments. One of these compounds showed significant inhibitory activity against DAO. The obtained docking poses were classified using machine learning and evaluated with molecular dynamics. The characteristics of its interaction were entirely different from those of the other DAO inhibitors.

Academic Significance and Societal Importance of the Research Achievements

統合失調症の陰性症状や認知機能障害の治療には既存の治療薬では不十分であるため、新しい治療原理による新規薬が必要とされている。本研究ではこれまでにない新しい手法で新規化合物を発見したため、大きな足掛かりになると考えている。本研究では特定の分子表面構造を標的とする阻害剤の探索に成功した。分子表面からタンパク質機能の阻害を行う化合物の探索手法はまだ十分に整備されていないため、我々が構築した方法はそうした課題の解決につながるものである。我々の手法は実験と計算科学を融合した新しい手法で幅広い応用の可能性がある。
