| Claim: |
1. Isolated peptide comprising or consisting of a sequence of amino acids selected from the group consisting of: the sequence of dermaseptin B2, the sequence of the precursor of dermaseptin B2; a sequence of amino acids having at least 80% identity with the sequences of dermaseptin B2 or the precursor of dermaseptin B2; and a fragment of these sequences; provided that the isolated peptide inhibits cell growth and/or proliferation, for use in the treatment or prevention of a proliferative disorder, an ocular lesion or an auto-immune disease. |
| Claim: |
2. The peptide for its use according to claim 1, said peptide comprising or consisting of a sequence of amino acids selected from the group consisting of: sequences SEQ ID NO: 1 and SEQ ID NO: 2; a sequence of amino acids having at least 80% identity with sequences SEQ ID NO: 1 or SEQ ID NO: 2; and a fragment of these sequences; provided that the isolated peptide inhibits cell growth and/or proliferation. |
| Claim: |
3. The peptide for its use according to claim 1, said peptide consisting of a sequence of amino acids selected from the group consisting of sequences SEQ ID NO: 1 and SEQ ID NO: 2. |
| Claim: |
4. The peptide for its use according to claim 1, said peptide comprising a chemical modification improving its stability and/or its bioavailability. |
| Claim: |
5. A pharmaceutical composition comprising a peptide as defined in claim 1. |
| Claim: |
6. A chimeric molecule comprising at least one peptide as defined in claim 1, wherein the said peptide is linked to: a) a therapeutic compound useful for the treatment of proliferative disorders; b) an enzyme capable of converting a molecule into a therapeutic compound useful for the treatment of proliferative disorders; or c) a carrier molecule. |
| Claim: |
7. A pharmaceutical composition comprising a chimeric molecule according to claim 6. |
| Claim: |
8. The chimeric molecule according to claim 6 for use in the treatment or prevention of a proliferative disorder, of an ocular lesion and/or of an auto-immune disease. |
| Claim: |
9. The peptide for its use according to claim 1 and a chimeric molecule for its use in the treatment or prevention of a proliferative disorder, of an ocular lesion and/or of an auto-immune disease, wherein said proliferative disorder is selected from solid tumours, leukaemia, tumour metastasis, benign tumours, haemangiomas, rheumatoid arthritis and hepatocellular adenoma. |
| Claim: |
10. A method for producing a chimeric molecule as defined in claim 6, comprising: a) the synthesis of a peptide via chemical route; and b) the conjugation of said peptide with a compound selected from: (i) a therapeutic compound useful for the treatment of proliferative disorders; (ii) an enzyme capable of converting a molecule into a therapeutic compound useful for the treatment of proliferative disorders; and (iii) a carrier protein. |
| Claim: |
11. The method according to claim 10, further comprising the formulation of said chimeric molecule in a pharmaceutical composition. |
| Claim: |
12. A nucleic acid comprising or consisting of a sequence coding for a peptide as defined in claim 1, for use in the treatment or prevention of a proliferative disorder, an ocular lesion or an auto-immune disease. |
| Claim: |
13. A vector comprising a nucleic acid according to claim 12, wherein said nucleic acid is functionally linked to one or more elements allowing the expression of said peptide, for use in the treatment or prevention of a proliferative disorder, an ocular lesion or an auto-immune disease. |
| Claim: |
14. The nucleic acid for its use according to claim 12 and a vector for its use wherein said nucleic acid is functionally linked to one or more elements allowing the expression of said peptide, for use in the treatment or prevention of a proliferative disorder, an ocular lesion or an auto-immune disease, and wherein said proliferative disorder is selected from solid tumour, a leukaemia, tumour metastasis, benign tumours, haemangioms, rheumatoid arthritis and hepatocellular adenoma. |
| Claim: |
15. A pharmaceutical composition comprising a nucleic acid as defined in claim 12 and a vector wherein said nucleic acid is functionally linked to one or more elements allowing the expression of said peptide, for use in the treatment or prevention of a proliferative disorder, an ocular lesion or an auto-immune disease. |
| Claim: |
16. The composition according to claim 5 further comprising a second therapeutic compound useful for the treatment of proliferative disorders, ocular lesions or auto-immune diseases. |
