Outline of Research at the Start

超高齢社会における健全かつ持続的な社会活動の確保は我が国が取り組むべき最重要課題のひとつとして位置付けられている。そこで本研究では,骨に高い親和性を示すポリリン酸エステル(PPE)が骨系細胞の分化や機能におよぼす影響を生化学的手法によって明らかにすること,また,同ポリマーによる骨疾病モデル動物の健全化を試み,骨治療に資するポリマーの創出するこを目指す。

Outline of Final Research Achievements

Biodegradable polyphosphoesters (PPEs) are of increasing interest due to their promising biomedical applications. Polyphosphodiesters (PPDEs) have mineral affinity and therefore are promising polymer drug candidates for bone disease treatment. However, their effects on osteoblasts are still unclear. In this study, we investigated the effect of PPDEs on bone cell function and clarified that PPDEs upregulated osteoblastic differentiation whereas downregulated osteoclast differentiation. Furthermore, biodistribution of PPDEs in osteoporosis mouse model was studied. PPDEs selectively accumulated in bone tissue. Due to the molecular diversity of polyphosphoesters, various types of polymeric prodrugs for bone disease treatment can be designed based on PPDEs.

Academic Significance and Societal Importance of the Research Achievements

人口の高齢化にともない運動器の問題は顕在化する。そのため,運動器疾患治療に関わる研究開発の重要性は益々高まっている。現在,骨粗鬆症や骨転移の治療にはビスホスホネートを代表とした様々な治療薬が適用されている。しかし,これらの治療薬は骨溶解の遅延のみに効果が限定されるものや,使用期間に制限があるものに限られ,骨のリモデリングを正常化する新たな骨治療薬の創出が依然として望まれている。本研究は,骨の健全化に資するポリマー医薬の創出を目指し実施され,骨の形成を促進し,骨の溶解を遅延する二重機能を示すPPEの獲得に成功した。PPEには薬剤を搭載することも可能であり,様々な骨疾患治療への応用が期待される。
