Abstract

The incorporation of metal binding sites into peptides is an elegant method for the stabilization of peptide microstructures. In order to do this, first amino acid derivatives have to be synthesized which bear metal ligand moieties like bipyridines, phosphanes, or catechols. By standard peptide coupling reactions those building blocks can be incorporated into peptide strands. Examples from the literature show that, depending on the system, different peptide structures are stabilized by addition of metal ions to appropriate artificial peptides. Thus, conformationally fixed α-helix-, β-sheet- or various turn/loop-motifs can be obtained.
