Abstract

A composition for treating keratin surfaces to stimulate selective catabolysis and improve cellular viability comprising at least one autophagy activator and at least one DNA repair enzyme, and a method for improving selective catabolysis and cellular viability by treating with the composition.

First claim

We claim:

1. A topical composition in aqueous solution or emulsion form comprising an extract from the genus Candida and at least one DNA repair enzyme, wherein the DNA repair enzyme is a base excision (BER) enzyme, and wherein the extract and DNA repair enzyme are present in amounts that exhibit a synergistic increase in cellular health and viability when in admixture and tested on dermal cells in vitro.

2. The composition of claim 1 wherein the extract from the genus Candida is Candida saitoana.

3. The composition of claim 2 wherein the Candida saitoana extract is an autophagy activator and inhibitor of mTOR.

4. The composition of claim 1 wherein the extract is from Candida saitoana and is present in combination with the DNA repair enzyme in an amount that improves cellular health and viability when compared to the same composition not containing the combination.

5. The composition of claim 1 further comprising inactivated bacterial lysates from Bifidobacterium.

6. The composition of claim 1 additionally comprising at least one proteasome activator.

7. The composition of claim 6 wherein the proteasome activator is algin, alginate, or hydrolyzed algin.

8. The composition of claim 1 additionally comprising a CLOCK or PER1 gene activator comprising:
(a) a peptide having from about 3 to 13 amino acid residues and of the formula (I) (SEQ ID No. 1):
R 1 -(AA) n -X 1 -S-T-P-X 2 -(AA) p -R 2 , wherein
X 1 represents threonine, serine, or is equal to zero,
X 2 represents an isoleucine, leucine, proline, valine, alanine, glycine, or is equal to zero,
AA represents any amino acid or derivative thereof, and n and p are whole numbers between 0 and 4,
R 1 represents the primary amine function of the N-terminal amino acid, either free or substituted by a protective grouping that may be chosen from either an acetyl group, a benzoyl group, a tosyl group, or a benzyloxycarbonyl group,
R 2 represents the hydroxyl group of the carboxyl function of the C-terminal amino acid, which may be substituted by a protective grouping that may be chosen from either a C 1 to C 20 alkyl chain or an NH 2 , NHY, or NYY group with Y representing a C 1 to C 4 alkyl chain, and
wherein said formula (I) sequence may contain substitutions of amino acids X 1 and X 2 with other chemically equivalent amino acids;

(b) a peptide having the amino acid sequence Ser-Pro-Leu-Gln-NH 2 ;
(c) cichoric acid; and
(d) mixtures thereof.

9. The composition of claim 8 wherein the CLOCK or PER1 gene activators are selected from the group consisting of:

S-T-P-NH 2

Ser-Thr-Pro-NH 2

(SEQ ID No. 2)

Y-V-S-T-P-Y-N-NH 2

Tyr-Val-Ser-Thr-Pro-Tyr-Asn-NH 2

(SEQ ID No. 3)

NH 2 -V-S-T-P-E-NH 2

NH 2 -Val-Ser-Thr-Pro-Glu-NH 2

(SEQ ID No. 4)

NH 2 -L-H-S-T-P-P-NH 2

NH 2 -Leu-His-Ser-Thr-Pro-Pro-NH 2

(SEQ ID No. 5)

CH 3 NH-R-H-S-T-P-E-NH 2

CH 3 -NH-Arg-His-Ser-Thr-Pro-Glu-NH 2

(SEQ ID No. 6)

CH 3 NH-H-S-T-P-E-CH 3 NH

CH 3 -NH-His-Ser-Thr-Pro-Glu-CH 3 -NH 2

and mixtures thereof.

10. The composition of claim 8 wherein the CLOCK or PER1 gene activators are selected from:

S-T-P-NH 2

Ser-Thr-Pro-NH 2

(SEQ ID No. 4)

NH 2 -L-H-S-T-P-P-NH 2

NH 2 -Leu-His-Ser-Thr-Pro-Pro-NH 2

and mixtures thereof.

11. The composition of claim 1 additionally comprising a CLOCK or PER1 gene activator selected from the group consisting of Tripeptide-32, Tetrapeptide-26, and mixtures thereof.

12. The composition of claim 1 wherein the BER enzyme is 8-oxogunanine DNA glycosylase (OGG1).

13. A method for increasing cellular viability and selective catabolysis in cells of keratin surfaces in need of such treatment comprising applying to the surface the composition of claim 1 .

14. The method of claim 13 wherein the cellular viability and selective autophagy activation results in improved cellular detoxification.

15. The method of claim 13 wherein the composition is applied at night prior to evening rest.

16. The method of claim 13 wherein the keratin surfaces are skin, hair, or nails.
