Outline of Final Research Achievements

Recent biochemical experiments have revealed that a variety of proteases play important roles in cancer invasion and metastasis. The receptor for the PA, uPAR, facilitates tumor cell invasion and metastasis by focusing on several ligands, including uPA, integrins and vitronectin. In the present study, we propose some peptides composed of these important residues and investigate the specific interactions and the binding affinity between uPAR and the peptides at an electronic level, using ab initio molecular simulations. With computational prediction algorithms and structure-based drug design, we identified KG6 that does not enter the pocket of its receptor. KG6 inhibited cancer cell invasion, without affecting cell viability, accompanied by the suppression of ERK-1 phosphorylation and then matrix metalloproteinase (MMP)-9 expression. KG6 did not show the acquired resistance for at least 3 months. These data were also confirmed by animal experiments.

Academic Significance and Societal Importance of the Research Achievements

癌治療としての低分子医薬品としてチロシンキナーゼ、PARP、Rafキナーゼ、MEK、CDK、プロテアソームに対する阻害薬などが開発されている。本邦において使用できる新規分子標的薬は、初回効果を発揮してもほとんどの患者は薬剤耐性獲得により治療効果が減弱するという、低分子医薬品に共通の欠点がある。そこで、我々が得意とする分子シミュレーション法によりペプチドを設計・試作することが可能である。本提案は、獲得耐性を生じにくい低分子医薬品の開発であるが、この技術はキナーゼドメインの鍵穴ポケットにも応用可能であり、他の低分子医薬品へ応用・展開が可能となる。
