| Outline of Final Research Achievements |
Peptides have recently gained much interest for the development of novel pharmaceutics because they possess varieties of biological activities depending on their amino acid sequences. However, there is a problem arising from poor proteolytic stability in living systems. One of the solutions to overcome this difficulty is installation of unnatural amino acid units into peptides. The present methodology to prepare such peptides relies on asymmetric construction of unnatural amino acid units and installation into peptide elongation process. But this methodology requires multi-step reactions before its application to peptide synthesis. In this research, a novel concept for preparation of such peptides, an asymmetric construction of unnatural amino acid units directly in a growing peptide chain, was developed. By applying this new methodology, I succeeded in synthesis of indolyl glycine-containing peptide.
