  • Publication number: 20090203881
    Abstract: The invention relates to SAEP II peptide dimers that mimic polymyxin B i.a. in its ability to bind non-covalently the lipopolysaccharide (LPS) of Gram-negative bacteria with high affinity, and therefore to detoxify LPS as polymyxin B does. The dimeric structure is maintained by a pair of disulphide bonds involving the two cystein residues present in the peptide sequence, which does not exceed 17 amino acids and essentially comprises cationic and hydrophobic amino acid residues. In the dimers of the invention, peptides may have a parallel or anti-parallel orientation. As a matter of example, a dimer of the invention is constituted by a peptide of formula NH2-Lys-Thr-Lys-Cys1-Lys-Phe-Leu-Leu-Leu-Cys2-COOH, either in a parallel or antiparallel dimeric form. SAEP II dimers are useful for treating or preventing septic shock and related disorders generated by Gram-negative bacteria infection. The invention also relates to LPS-peptide complexes in which LPS and SAEP II dimers are non-covalently bound together.

  • Patent number: 7507718
    Abstract: The invention relates to SAEP II peptide dimers that mimic polymyxin B i.a. in its ability to bind non-covalently the lipopolysaccharide (LPS) of Gram-negative bacteria with high affinity, and therefore to detoxify LPS. The dimeric structure is maintained by a pair of disulphide bonds between two cystein residues present in the peptide sequence, which does not exceed 17 amino acids and essentially comprises cationic and hydrophobic amino acid residues. The peptides in the dimers may have a parallel or anti-parallel orientation. SAEP II dimers are useful for treating or preventing septic shock and related disorders generated by Gram-negative bacteria infection. The invention also relates to LPS-peptide complexes in which LPS and SAEP II diners are non-covalently bound together. These complexes are useful as vaccinal agents against Gram-negative bacteria infection.

  • Patent number: 6951652
    Abstract: A vaccine is disclosed which is useful for protecting a host from Gram negative infections and the effects of endotoxin, therefore preventing sepsis and septic shock. The vaccine is prepared by combining LPS free or in conjugate form with a stoichiometric excess of a peptide of the formula: (a) (A)n wherein A is Lysine or Arginine and n is an integer with a minimum value of 7; (b) (AB)m wherein A is Lysine or Arginine and B is a hydrophobic amino acid selected from the group consisting of Valine, Leucine, Isoleucine, Tyrosine, Phenylalanine and Tryptophan; m is an integer with a minimum value of 3; and (c) (ABC)p wherein A is a cationic amino acid which is Lysine or Arginine; B and C are hydrophobic amino acids which may be the same or different and are selected from the group consisting of Valine, Leucine, Isoleucine, Tyrosine, Phenylalanine and Tryptophan; p is an integer with a minimum value of 2.
