All‐D‐magainin: chirality, antimicrobial activity and proteolytic resistance

Abstract
All‐D‐magainin‐2 was synthesized to corroborate experimentally the notion that the biological function of a surface‐active peptide stems primarily from its unique amphiphilic α ‐helical structure. Indeed, the peptide exhibited antibacterial potency nearly identical to that of the all‐L‐enantiomer. Being highly resistant to proteolysis and non‐hemolytic all‐D‐magainin might have considerable therapeutic importance.
