Abstract

This invention relates to certain chirally-correct mitoprotectant phosphorylated heterocyclic agents [formula (I)], which are useful for the treatment of dermatological disorders that include challenged skin from cancer, diabetes, radiation treatments, chemotherapy, and sun-burn; mitochondrial dysfunction; age spots; acne, loss of cellular antioxidants; skin changes associated with aging including collagen loss, loss of skin pliability, loss of skin suppleness, skin wrinkles and fine lines, oxidation, damage from radiation, damage from free radicals, and damage from UV; dry skin; xerosis; ichthyosis; dandruff; brownish spots; keratoses; melasma; lentigines; liver spots; skin pigmentation including pigmented spots, dark circles under the eyes, darkened skin, and blemishes; oily skin; warts; eczema; pruritic skin; psoriasis; inflammatory dermatoses; topical inflammation; disturbed keratinization; scalp dryness; skin depigmentation, and combinations thereof;

Claims (26)

1. A complex of an L-amino acid derivative and a heterocyclic compound for topical application; wherein, said L-amino acid derivative is selected from the group consisting of an L-amino acid, L-amino ester, L-peptide, and hydrolyzed proteins, and, wherein, said complex is selected from the group consisting of:

wherein,

R is an organic agent selected from the group consisting of,

wherein;

R 1 is selected from the group consisting of H, and C 1 -C 20 alkyl esters.

2. The complex of claim 1 , wherein said compound is L-proline-benfotiamine, the chemical name of which is L-Proline-S-[(2Z)-2-{[(4-amino-2-methylpyrimidin-5-yl)methyl](formyl)amino}-5-(phosphonooxy)pent-2-en-3-yl]benzenecarbothioate (1:1), of formula),

3. The complex of claim 1 , wherein said complex is Glutathione-D-glucose-6-phosphate, the chemical name of which is glutathione-D-glucopyranose 6-phosphate (1:1) or γ-L-Glutamyl-L-cysteinylglycine-D-glucopyranose 6-phosphate (1:1), of formula (),

4. The complex of claim 1 , wherein said compound is β-Alanyl-L-histidine-D-glucose-6-phosphate, the chemical name of which is L-carnosine-D-glucopyranose 6-phosphate (1:1), of formula (),

5. A composition comprising the compound of claim 1 and a carrier for topical application.

6. A composition comprising the compound of claim 1 and a carrier to treat a dermatological disorder selected from the group consisting of sun-burn; age spots, acne, skin wrinkles including fine lines, dry skin, liver spots, pigmented spots, dark circles under the eyes, skin pigmentation including darkened skin, blemishes, oily skin, inflammation, and combinations thereof.

7. A composition of claim 6 , wherein said dermatological disorder is sun-burn.

8. A method of treating a dermatological disorder selected from the group consisting of sunburn, age spots, acne, wrinkles, fine lines, dry skin, liver spots, pigmentation spots, dark circles under the eyes, skin pigmentation, blemishes, oily skin, inflammation, or combinations thereof comprising mixing of, (i) a mitoprotectant compound of claim 1 , and (ii) an antioxidant agent, and (iii) an anti-inflammatory agent, and (iv) a collagen-boosting agent with a carrier, and wherein said mixture is applied to skin.

9. The method of claim 8 , wherein said mitoprotectant complex is L-carnosine-D-glucose-6-phosphate of formula,

10. The method of claim 8 , wherein antioxidant agent is hypericin.

13. The method of claim 8 for the treatment of dermatological disorder selected from the group consisting of sun-burn, age spots, acne, skin wrinkles including fine lines, dry skin, liver spots, pigmented spots, dark circles under the eyes, skin pigmentation including darkened skin, blemishes, oily skin, inflammation, and combinations thereof.

14. The method of claim 13 , wherein said dermatological disorder is skin wrinkles including fine lines.

15. A process for making compound of claim 1 , which comprises combining; (i) An organic phosphorylated agent, and

(ii) An L-amino acid derivative, and

(iii) A liquid reaction medium, and

(iv) Heating at 50 to 120 degrees Celsius.

16. The process of claim 15 , wherein said organic phosphorylated agent is D-glucose-6-phosphate.

17. The process of claim 15 , wherein said L-amino acid derivative is L-Carnosine.

18. The process of claim 15 , wherein said liquid reaction medium is selected from the group comprising water, ethanol, ethylene glycol, propylene glycol, butylene glycol, pentylene glycol, hexylene glycol, polyethylene glycol, polypropylene glycol, glycerin, Diglycerin, polyglycerol, sorbitol, polysorbate, methylpropanediol, ethoxydiglycol, dimethyl sulfoxide, N-methylpyrrolidone, pyrrolidone, and combinations thereof.

19. The process of claim 18 , wherein said liquid reaction medium is water.
