Abstract

The present invention relates to a peptide comprising or consisting of the following amino acid sequence: A0-A1-A2-A3-A4-A5-A6-A7-A8-A9-A10-A11-A12 (formula II), wherein A0 is a hydrophobic amino acid residue or is absent; A1, A4, A7, A8, A12 each are a hydrophobic amino acid residue; and A2, A6, A9, A10 each are a basic amino acid residue; A5 is an alanine or a basic amino acid residue; A3, A11 each are a basic amino acid residue, or a hydrophobic amino acid residue; or a peptidomimetic thereof; wherein the basic amino acid residues are selected from the group consisting of arginine, lysine and histidine; wherein the hydrophobic amino acid residues are selected from the group consisting of leucine, alanine, isoleucine, valine, methionine and phenylalanine; and wherein said peptide or peptidomimetic has antimicrobial and/or antiviral activity. Furthermore, the invention relates to a nucleic acid molecule encoding the peptide of the invention, a vector comprising the nucleic acid molecule as well as a host cell comprising the nucleic acid molecule or the vector. The present invention also relates to a method for producing the peptide of the invention, a composition as well as to the peptide or peptidomimetic of the invention for use in treating infectious diseases.
