The invention relates to a peptide or peptide derivative having the general formula: Sub 1 -X 1 -D 2 K 3 -P 4 -P 5 -Y 6 -L 7 -P 8 -R 9 -P 10 -X 2 -P 12 -P 13 -R 14 -X 3 -I 16 -P 17 /Y 17 -N 18 -N 19 -X 4 -Sub 2 , wherein X 1 is a non-polar, hydrophobic group or a positively charged group, D 2 is asparagine or glutamine, K 3 , X 2 , and X 4 are positively charged groups, X 3 is a positively charged group, proline, or a proline derivative; L 7 and I 16 are non-polar, hydrophobic groups, Y 6 and Y 17 are tyrosine, R 9 and R 14 are arginine, N 18 and N 19 are asparagine or glutamine, P 4 , P 5 , P 8 , P 10 , P 12 , P 13 , and P 17 are proline, hydroxyproline, or derivatives thereof, wherein possibly one or two of the groups selected from D 2 , P 4 , P 5 , P 8 , P 10 , P 12 , P 13 , P 17 , and Y 17 are replaced by an arbitrary group and/or P 13 and R 14 are exchanged, Sub 1 is the free or modified N-terminus, and Sub 2 is the free or modified C-terminus. The invention further relates to the use of the peptides and peptide derivatives in medicine, as an antibiotic, in a disinfectant or cleaning agent, as a preservative or in a packaging material, in pharmaceutical research, or in a screening method.
