Abstract
The present invention is directed to methods of using pro-NAD agents capable of enhancing the dermal and epidermal skin cell NAD content. These pro-NAD agents may be administered topically, orally, or parenterally to enhance DNA repair and other protective responses to DNA damage. The invention further relates to pharmaceutical compositions comprising pro-NAD agents that effectively elevate intracellular NAD content. Finally, the invention relates to the method of using the pro-NAD agents to treat disorders such as sunburn and other skin deterioration that results from DNA damage in skin cells.
Claims11
A method for treating or slowing skin deterioration in a subject in need thereof, comprising administering to said subject a composition consisting essentially of a nicotinic acid alkyl ester, wherein the alkyl moiety of said nicotinic acid ester is a straight alkyl chain of from 12 to 16 carbon atoms, in an amount sufficient to increase intracellular NAD content in skin cells of said subject, and to treat or to slow skin deterioration thereby.
A method for treating or slowing skin deterioration in a subject in need thereof, comprising administering a composition to said subject which comprises a nicotinic acid alkyl ester, wherein the alkyl moiety of said nicotinic acid alkyl ester is a straight chain alkyl of from 10 to 22 carbon atoms, and further comprises at least one functional group selected from the group consisting of thiol, alcohol, amine, caboxylic acid, oninum, carboxylic anhydride, carboxylic ester, acylhalide, amide, nitrile, aldehyde, ketone, imine, ether, sulfide, halcide, nitro, nitroso, azide and drazo group, in an amount sufficient to increase intracellular NAD content in skin cells of said subject and to treat or to slow skin deterioration thereby.
