CYCLIC PEPTIDES AGAINST THE OUTER MEMBRANE PROTEIN A (OMPA) FOR THE TREATMENT OF INFECTIONS CAUSED BY GRAM NEGATIVE PATHOGENS

摘要

Peptides against the external protein A (OmpA) are provided for the treatment of infections caused by Gram negative pathogens, especially Acinetobacter baumanii, Escherichia coli or Pseudomonas aeruginosa. Preferred cyclic hexapeptides comprise tryptophan, proline and arginine,and a preferred cyclic hexapeptide has the sequence c- (WPRWPR). Variants thereof with modified amino acids, D-amino acids or different order of the amino acids in the cyclic hexapeptide are also disclosed.
