Patent ID: 8802815

Claim:
An isolated peptide comprising the 20 to 24 amino acids following sequence (I): P a -X 1 -Phe-Trp-X 2 -X 3 -P b (I) (SEQ ID NO: 1) in which: P a represents a sequence comprising 10 to 12 amino acids selected from the sequences: (SEQ ID NO: 3) Phe-Gly-Ser-Arg-Lys-Phe-Ser-Tyr-Lys-Ala (SEQ ID NO: 4) Asn-Phe-Gly-Ser-Arg-Lys-Phe-Ser-Tyr-Lys-Ala (SEQ ID NO: 5) Ser-Asn-Phe-Gly-Ser-Arg-Lys-Phe-Ser-Tyr-Lys-Ala X 1 is a lysine, arginine or histidine residue; X 2 is a threonine or lysine residue; X 3 is an aspartate or glutamate residue; and P b represents a sequence comprising 5 to 7 amino acids selected from the sequences: Val-Thr-Thr-Ser-Glu (SEQ ID NO: 6) Val-Thr-Thr-Ser-Glu-Leu (SEQ ID NO: 7) Val-Thr-Thr-Ser-Glu-Leu-Gly; (SEQ ID NO: 8) or a peptide resistant to proteolysis derived from sequence (I) by one or more chemical modification(s).
