Synthesis of a 53-residue peptide with EGF activity
Abstract
Mouse epiderma growth factor (EGF), which consists of 53 amino acids with 3 disulphide bridges, was synthesized in a conventional manner by assembling 15 peptide fragments of established purity followed by thioanisole-mediated deprotection with trifeluoromethanesulphonic acid in trifuoroacetic acid and subsequent air oxidation.
