Outline of Final Research Achievements |
In this study, I focused on terrein, a small molecule with anti-inflammatory properties, and analyzed its effects on inflammatory bone-destroying pathologies using various mouse disease models to investigate the potential of terrein as a therapeutic agent for bone-destroying diseases. The results of this study showed that 1) terrein inhibited bone destruction in mouse ovariectomized osteoporosis model and ligature-induced periodontitis model, and 2) terrein inhibited protein phosphorylation of PKC-alpha/beta II in the RANKL signaling pathway. These results suggest that terrein has potential as a drug candidate for the treatment of bone-destroying diseases.

Academic Significance and Societal Importance of the Research Achievements |
本研究成果において,terreinは既存の骨破壊抑制薬(ビスフォスフォネート製剤)とは異なる作用機序によって破骨細胞分化を抑制できる可能性が示唆された。Terreinは低分子化合物であることから,経口投与が可能といった幅広い創薬への応用が期待される。将来的には歯周炎を始めとする炎症性骨破壊疾患に対する治療薬への応用を検討し,健康長寿社会構築に貢献できる化合物になることが期待される。
