| Outline of Final Research Achievements |
Peptides that have biological activities are called functional peptides. Many types of functional peptides have been found to date and has been designed for development of peptide drug. In the present study, following 3 topics were investigated, 1) fabrication of peptide library including unnatural amino acid, 2) screening of intracellular functional peptide conjugated with cell penetrating peptide (CPP), 3) development of the smart machinery for removal of CPP in intracellular space. Related to the last topic, we have established the methodology for disulfide bond formation of all peptides on peptide array. In addition, we have been developed a novel synthesis method of hetero-dimerized peptide using intramolecular disulfide bonding between main- and sub-chain of lysin.

| Academic Significance and Societal Importance of the Research Achievements |
細胞内に導入し内部に侵入した直後に切断できる仕組みは細胞内機能性ペプチドの探索において必要不可欠な技術である。また環状化ペプチドライブラリーによる探索も高機能ペプチドの探索において重要な手法であり、細胞内機能性ペプチド医薬の開発につながる技術である。
