Application Number: | 12/700,843 |
Patent Claims: | 1. A method for reducing skin wrinkles comprising administering to a subject in need thereof a composition comprising an effective amount of a histone deacetylase inhibitor
or a pharmaceutically acceptable salt thereof, and a cosmetically or pharmaceutically acceptable carrier, wherein the histone deacetylase inhibitor is selected from the group consisting of trichostatin A, trichostatin C, oxamflatin, trapoxin A, FR901228,
apicidin, HC-Toxin, WF27082, chlamydocin, salicylihydroxamic acid, suberoylanilide hydroxamic acid, azelaic bishydroxamic acid, azelaic-1-hydroxamate-9-an-ilide, M-carboxycinnamic acid bishydroxamide, 6-(3-chlorophenylureido)carpoic hydroxamic acid,
MW2796, MW2996, sodium butyrate, arginine butyrate, isovalerate, valerate, 4-phenylbutyrate, sodium phenylbutyrate, propionate, butrymide, isobutyramide, 3-bromopropionate, valproic acid, valproate, tributyrin, MS-27-275, a 3'-amino derivative,
depudecin, and scriptaid.
2. The method of claim 1, wherein the composition is a topical composition and the administering step is conducted by applying the composition to a surface of skin in need thereof of the subject. 3. The method of claim 1, wherein the histone deacetylase inhibitor is trichostatin A or trichostatin C. 4. The method of claim 1, wherein the histone deacetylase inhibitor is selected from the group consisting of oxamflatin, trapoxin A, FR901228, apicidin, HC-Toxin, WF27082, and chlamydocin. 5. The method of claim 1, wherein the histone deacetylase inhibitor is selected from the group consisting of salicylihydroxamic acid, suberoylanilide hydroxamic acid, and azelaic bishydroxamic acid. 6. The method of claim 1, wherein the histone deacetylase inhibitor is selected from the group consisting of azelaic-1-hydroxamate-9-an-ilide, M-carboxycinnamic acid bishydroxamide, 6-(3-chlorophenylureido) carpoic hydroxamic acid, MW2796, and MW2996. 7. The method of claim 1, wherein the histone deacetylase inhibitor is selected from the group consisting of sodium butyrate, arginine butyrate, isovalerate, valerate, 4-phenylbutyrate, sodium phenylbutyrate, propionate, butrymide, isobutyramide, 3-bromopropionate, valproic acid, valproate, and tributyrin. 8. The method of claim 1, wherein the histone deacetylase inhibitor is MS-27-275 or a 3'-amino derivative thereof. 9. The method of claim 1, wherein the histone deacetylase inhibitor is depudecin or scriptaid. 10. The method of claim 1, wherein the histone deacetylase inhibitor is present in an amount of from 0.00001% to 100% by weight of the composition. 11. The method of claim 10, wherein the histone deacetylase inhibitor is present in an amount of from 0.0001% to 10% by weight of the composition. 12. The method of claim 1, wherein the composition is a cream, an ointment, a gel, a paste, a powder, an aqueous solution, a spray, a suspension, a dispersion, a slave, a lotion, a patch, a suppository, a liposome formation, a mouth wash, an enema, an injection solution, an eye drop, an ear drop, a drip infusion, a microcapsule, or a nanocapsule. 13. The method of claim 1, wherein the composition further comprises a penetration enhancing agent, or a pH adjusting agent to provide a formulation pH in the range of approximately 2.0 to 13.0. 14. The method of claim 1, wherein the composition is used as an adjuvant treatment following laser surgery or laser dermabrasion treatment to enhance aged and injured skin rejuvenation. 15. The method of claim 1, wherein the method further comprises administering to the subject a second agent that comprises lidocaine, epinephrine, collagenase, clostridium histolyticum, or combinations thereof. 16. The method of claim 15, wherein the composition and the second agent are systemically or topically administered simultaneously or sequentially. 17. The method of claim 1, wherein the method further comprises, before the administering the composition, identifying a subject having skin wrinkles. 18. The method of claim 1, wherein the method further comprises, after the administering the composition, examining the subject for the effect of the composition on skin wrinkles. |
