Abstract

The invention relates to an aptamer that has a G-quadruplex structure and is able to inhibit the enzymatic activity of the MMP-9 protein, as well as to the dermatological and cosmetic uses thereof.

First claim

The invention claimed is:

1. A method of using a cosmetic composition for treating the appearance of skin aging or for slowing or attenuating the effects thereof comprising topically administering a cosmetic composition comprising a G-quadruplex-structured aptamer capable of inhibiting the enzymatic activity of MMP-9 protein, wherein the aptamer is a DNA aptamer comprising at least one nucleotide sequence selected from the group consisting of the sequences SEQ ID NO: 1 to SEQ ID NO: 4.

2. The method of claim 1 , wherein the aptamer is resistant to nucleases.

3. The method of claim 1 , wherein the nucleotide sequence comprises at least 1 to 24 contiguous nucleotides of the sequence SEQ ID NO: 30 flanked at its 5′ end, and/or at least 1 to 23 contiguous nucleotides of the sequence SEQ ID NO: 31 flanked at its 3′ end.

4. A method of using a cosmetic composition for treating the appearance of skin aging or for slowing or attenuating the effects thereof comprising topically administering a cosmetic composition comprising a G-quadruplex-structured aptamer capable of inhibiting the enzymatic activity of MMP-9 protein, wherein the aptamer is a DNA aptamer comprising at least one nucleotide sequence selected from the group consisting of the sequences SEQ ID NO: 32 to SEQ ID NO: 59.

5. A method of using a composition comprising a G-quadruplex-structured aptamer capable of inhibiting the enzymatic activity of MMP-9 protein, wherein the aptamer is a DNA aptamer comprising at least one nucleotide sequence selected from the group consisting of the consensus sequences SEQ ID NO: 1 to SEQ ID NO: 4 for-treating pathologies associated with MMP-9 overexpression and/or hyperactivity comprising administering said composition topically to a subject.

6. The method of claim 5 , wherein said pathologies are skin diseases selected from inflammatory diseases of the skin, skin tumors, skin lesions, cicatrization pathologies, bullous dermatoses, noninfectious granulomatous diseases, granuloma annulare, necrobiosis lipedema, and skin damage related to ultraviolet rays.

7. A method of using a cosmetic composition for treating the appearance of skin aging or for slowing or attenuating the effects thereof comprising topically administering a cosmetic composition comprising a G-quadruplex-structured aptamer capable of inhibiting the enzymatic activity of MMP-9 protein, wherein the aptamer is a DNA aptamer comprising at least one nucleotide sequence selected from the group consisting of the sequences SEQ ID NO: 6 to SEQ ID NO: 29.

8. The method of claim 5 , wherein said pathologies are skin diseases selected from psoriasis, basal cell carcinoma, chronic wounds, bullous pemphigoid, and sarcoidosis of the skin.

9. The method of claim 1 , wherein the aptamer comprises at least one nucleotide sequence selected from the group consisting of the sequences SEQ ID NO: 11 to SEQ ID NO: 27 and SEQ ID NO: 32 to SEQ ID NO: 52.

10. The method of claim 2 , wherein the aptamer comprises at least one nucleotide sequence selected from the group consisting of the sequences SEQ ID NO: 11 to SEQ ID NO: 27 and SEQ ID NO: 32 to SEQ ID NO: 52.

11. The method of claim 9 , wherein the aptamer comprises at least 1 to 24 contiguous nucleotides of the sequence SEQ ID NO: 30 flanked at its 5′ end, and/or at least 1 to 23 contiguous nucleotides of the sequence SEQ ID NO: 31 flanked at its 3′ end.

12. The method of claim 10 , wherein the aptamer comprises at least 1 to 24 contiguous nucleotides of the sequence SEQ ID NO: 30 flanked at its 5′ end, and/or at least 1 to 23 contiguous nucleotides of the sequence SEQ ID NO: 31 flanked at its 3′ end.

13. The method of claim 9 , wherein the nucleotide sequence is selected from the group consisting of the sequences SEQ ID NO: 32 to SEQ ID NO: 52.

14. The method of claim 10 , wherein the nucleotide sequence is selected from the group consisting of the sequences SEQ ID NO: 32 to SEQ ID NO: 52.
