Outline of Research at the Start

分子量が小さく化学合成が可能で、強く標的に結合するペプチドや小型タンパク質が、抗体医薬の代替となる中分子薬として期待されている。申請者はこれまでに標的結合ペプチドの「構造ゆらぎ」制御法を開発し、小型抗体代替分子FLAPのデザイン理論の確立を進めてきた。本研究ではさらに高性能な抗体代替分子を創出することを目指して、抗体と標的との強力な相互作用における「多点結合」の重要性に着目し、MDシミュレーションを駆使して「多点結合」可能な小型抗体代替分子Multi-FLAPのデザイン理論の確立に挑戦する。

Outline of Final Research Achievements

Antibody drugs have been extensively developed as molecular-targeted therapeutic drugs for various diseases including cancer. However, since an antibody has a large molecular size and a complex structure, its clinical application is limited. Therefore, a design strategy for developing the small antibody mimetics is required.
In this study, we successfully developed an antibody mimetic small protein, Multi-FLAP, which is one-fifteenth the size of an antibody, by computational design and screening. We also found that by designing two antigen-binding regions in one molecule, a strong binding affinity can be obtained due to the synergistic effect. Furthermore, we have developed a strategy to improve pharmacokinetics of Multi-FLAP for future clinical applications.

Academic Significance and Societal Importance of the Research Achievements

抗体医薬は分子サイズが大きく複雑な構造を持つため、適用疾患が限られることや、製造コストおよび治療コストが非常に高額であることなど、新たな課題が顕在化している。本研究でデザイン理論を構築したMulti-FLAPは、分子サイズが小さいため化学合成で安価に調整でき、さらに組織浸透性の向上により適用疾患の拡大に繋がると期待できる。本研究はすべての人々に安価かつ高品質な医療を提供することを目指している。
