== Publication Abstract from PubMed == | |||
Previously, we identified a potent antimicrobial analogue of temporin L (TL), [Pro3]TL, in which glutamine at position 3 was substituted with proline. In this study, a series of analogues, where the position 3 was substituted with non-natural proline derivatives, was investigated for the correlation between the conformational properties of the compounds and their antibacterial, cytotoxic and hemolytic activities. Non-natural proline analogues with substituents at position 4 of the pyrrolidine ring were considered. Structure-activity relationship studies of these analogues were performed by means of antimicrobial and cytotoxicity assays along with circular dichroism (CD) and NMR spectroscopy analysis for selected compounds. The most promising peptides were additionally evaluated for their activity against some representative veterinary microbial strains to compare with those from human strains. We identified novel analogues with interesting properties that make them attractive lead compounds. | |||
