title: Design and synthesis of novel antibacterial peptide-resin conjugates.
abstract: We synthesized a novel peptide-resin conjugate by immobilizing beta-sheet antibacterial peptide on PEG-PS resin. The peptide-resin conjugate, similar to cationic antimicrobial peptides, demonstrated unique properties such as potent antibacterial activity, no hemolytic activity, lipid membrane perturbation activity, and potent synergism with vancomycin. Specially, the peptide-resin conjugate showed a more increased lipid membrane perturbation activity in comparison to unbound beta-sheet antibacterial peptide.
