Versatile synthesis of fluorescent, cross-linked peptides as biological probes with the advantage of high helix content

摘要

A variety of fluorophores were introduced at the N-termini of short peptides for use as biological-probes. The fluorescent peptides were cross-linked with a diacetylenic cross-linking agent between the amino acid side chains of ornithine (Orn) residues to produce peptides with high helix content.
