  • Patent number: 11396531
    Abstract: The present disclosure relates to a peptide comprising at least five amino acid residues, wherein at least one amino acid residue is modified to an epsilon-lysine, delta-ornithine, gamma-2,4-diaminobutyric acid, beta-2,3-diaminopropionic acid, with the peptide also comprising at least one non-epsilon lysine, non-delta-ornithine, non-gamma-2,4-diaminobutyric acid or non-beta-2,3-diaminopropionic acid, and wherein the peptide displays a reduced or no cytotoxicity when compared to an equivalent non-modified peptide. In a preferred embodiment, the modifications are to the melittin or mastoparan B peptides, and comprise the substitution of at least one a-lysine residue for an ?-lysine residue, and the modified peptides display antimicrobial activity.
