Outline of Research at the Start

タンパク質分解誘導剤(PROTAC)の創製には、標的タンパク質の適切なリガンドが必要であり、かつ数多くの最適化を要する。そのため、簡便に設計・合成可能かつ幅広い標的に適応可能なPROTACの開発基盤技術が強く求められる。本研究では、ペプチドのステープル化を基盤としたペプチド性PROTACの開発により効率的に広範に適用可能なPROTACの創製を実現する革新的分子技術を確立することを目指す。

Outline of Final Research Achievements

This study aims to establish molecular technologies for the efficient and broadly applicable development of peptide-based proteolysis-targeting chimeras (PROTACs) through peptide stapling strategies. We focused on lysine-specific demethylase 1 (LSD1) as the target protein and conducted research on developing peptide-based PROTACs. We designed and synthesized novel LSD1 ligand peptides incorporating non-natural amino acids, as well as various cross-linking chains used for peptide stapling. By conjugating these components, we prepared multiple stapled peptides. The synthesized stapled peptides were suggested to possess LSD1 degradation-inducing activity.

Academic Significance and Societal Importance of the Research Achievements

タンパク質分解誘導薬(PROTAC)の創製には、標的タンパク質の適切なリガンドが必要であり、各リガンドの最適化、リンカーとのリガンドの結合部位の精査、リンカーの長さや種類の最適化等非常に多くの条件検討が必要であるため、簡便に設計・合成可能かつ幅広い標的に適用可能なPROTACの開発基盤技術が強く求められる。
本研究では、ペプチドのステープル化戦略を活用し、リシン特異的脱メチル化酵素1(LSD1)を標的タンパク質としたペプチド性PROTAC候補化合物を創製した。本戦略は、ペプチド性PROTACの創製を簡略化し、高い汎用性が期待される。
