Outline of Final Research Achievements

We have conducted mechanism studies of three Parkinson’s disease (PD) drug-seeds, which were obtained by the screening for metabolome analysis of PD and for clearance of protein aggregation seen in the brain of PD patients. We found that they function by targeting inhibition of Keap1-Nrf2 binding, activation of PLC -mediated TFEB transcription activity, and stimulation of liquid-liquid phase separation of target protein, respectively, thereby showing neuro-protection in PD-model neuronal cells.

Academic Significance and Societal Importance of the Research Achievements

PDのメタボローム解析研究の成果から,治療薬シードの発見および作用機構解析を行ったことでメタボローム 解析研究がバイオマーカー探索だけでなく直接創薬研究に展開できることを示した.また,ケミカルバイオロジーの手法でタンパク質凝集をクリアランスする新しいメカニズムを提唱することができ,このことは他の神経変性疾患の創薬研究にも応用できる可能性を持つ重要性を有している.
