Decelerated chirality interconversion of an optically inactive 3(10)-helical peptide by metal chelation.
A dynamically optically inactive 3(10)-helical peptide possessing metal chelating ability between the side-chains at the i and i + 3th residues was synthesized, and its metal complexes were shown to stabilize the peptide structure and the helical sense.
