Outline of Final Research Achievements |
Peptoid is emerging as a new therapeutic candidate that potentially overcomes the limitations of peptides for therapeutic applications such as poor membrane permeability. In this study, we conducted a study on N-substituted β-peptide that is a derivative of regular peptoid. We established a new synthetic method for N-substituted β-peptide and developed a molecular design in which substituents are introduced on backbone carbons of the oligomers to realize conformationally constrained N-substituted β-peptides. As a result, we successfully produced new N-substituted β-peptides that form stable secondary structures. The new synthetic oligomers produced in this study are potentially useful as scaffolds for inhibitors of intramolecular proteins.
