摘要
A modified tryptophan, beta-[2(2,2,5,7,8-pentamethylchroman-6-sulphonyl)-indol-3-yl]alanine, Trp(2-Pmc) = Tpe has been synthesized. Replacement of tryptophan in a bovine lactoferricin model peptide with the modified tryptophan resulted in peptides with a substantially increased antibacterial activity against Escherichia coli and Staphylococcus aureus. The most active peptides against each bacterial strain displayed minimal inhibitory concentrations of 7.5 mug/ml. Copyright (C) 2002 European Peptide Society and John Wiley Sons, Ltd.
