摘要

The family of antibacterial proline-rich peptides, originally isolated from insects, shows remarkable activity against diverse bacterial and fungal pathogens. While more and more bacterial pathogens become resistant to common drugs, this part of insect innate immunity provides a new promising approach to develop future peptide-drugs. Short proline-rich peptides, e.g. drosocin (fruit fly), formaecin (red bulldog ant) and metalnikowin (green shield bug), possess a significant sequence homology and share a common mechanism of action. The combination or insertion of sequence-regions from different native antibacterial peptide sequences may offer several advantageous effects including further reduction of toxicity and broadening of the antimicrobial activity. The aim of this study was to synthesize different proline-rich 15 to 22 mer peptides taken from the literature, as well as combinations with C- and N-terminal fragments of drosocin and formaecin.
