Title: Acyl deoxyribonucleoside derivatives and uses thereof
Abstract:The invention relates to compositions comprising acyl derivatives of 2'-deoxyribonucleosides. The invention also relates to methods of treating or preventing radiation, mutagen and sunlight-induced biological damage, and methods for improving wound healing and tissue repair, comprising administering the compositions of the present invention to an animal.
Inventor(s): von Borstel; Reid Warren (Darnestown, MD), Bamat; Michael Kevin (Darnestown, MD)
Assignee: Pro-Neuron, Inc. (Gaithersburg, MD)
Filing Date:Sep 21, 1994
Application Number:08/309,572
Claims:1. A method for treating radiation induced cellular damage comprising administering to an animal in need of such treatment at least one compound in an amount to said treatment, selected from the groups of compounds having the formulae: ##STR19## wherein R.sub.1, R.sub.2, and R.sub.3 are the same or different and each is H or an acyl group derived from a carboxylic acid, provided that at least one of said substituents R.sub.1, R.sub.2, and R.sub.3 on each of said groups of compounds is not hydrogen, and provided that R.sub.3 is not a fatty acid, or pharmaceutically acceptable salts thereof.

2. A method for treating sunlight induced cellular damage comprising administering to an animal in need of such treatment at least one compound in an amount to effect said treatment, seleted from the groups of compounds having the formulae: ##STR20## wherein R.sub.1, R.sub.2, and R.sub.3 are the same or different and each is H or an acyl group derived from a carboxylic acid, provided that at least one of said substituents R.sub.1,

R.sub.2, and R.sub.3 on each of said groups of compounds is not hydrogen, and provided that R.sub.3 is not a fatty acid, or pharmaceutically acceptable salts thereof.

3. A method for treating mutagen induced cellular damage comprising administering to an animal in need of such treatment at least one compound in an amount to effect said treatment, selected from the groups of compounds having the formulae: ##STR21## wherein R.sub.1, R.sub.2, and R.sub.3 are the same or different and each is H or an acyl group derived from a carboxylic acid, provided that at least one of said substituents R.sub.1, R.sub.2, and R.sub.3 on each of said groups of compounds is not hydrogen, and provided that R.sub.3 is not a fatty acid, or pharmaceutically acceptable salts thereof.

4. A method as recited in claim 1 wherein R.sub.1, R.sub.2, and R.sub.3 are the same or different and each is an acyl group derived from a carboxylic acid selected from the group consisting of pyruvic acid, lactic acid, enolpyruvic acid, an amino acid, a fatty acid, lipoic acid, nicotinic acid, pantothenic acid, succinic acid, fumaric acid, p-aminobenzoic acid, betahydroxybutyric acid, orotic acid and carnitine.

5. A method as recited in claim 2 wherein R.sub.1, R.sub.2, and R.sub.3 are the same or different and each is an acyl group derived from a carboxylic acid selected from the group consisting of pyruvic acid, lactic acid, enolpyruvic acid, an amino acid, a fatty acid, lipoic acid, nicotinic acid, pantothenic acid, succinic acid, fumaric acid, p-aminobenzoic acid, betahydroxybutyric acid, orotic acid and carnitine.

6. A method as recited in claim 3 wherein R.sub.1, R.sub.2, and R.sub.3 are the same or different and each is an acyl group derived from a carboxylic acid selected from the group consisting of pyruvic acid, lactic acid, enolpyruvic acid, an amino acid, a fatty acid, lipoic acid, nicotinic acid, pantothenic acid, succinic acid, fumaric acid, p-aminobenzoic acid, betahydroxybutyric acid, orotic acid and carnitine.

7. A method as in claim 1 wherein said at least one compound comprises at least one compound selected from Group I and at least one compound selected from Group II.

8. A method as in claim 2 wherein said at least one compound comprises at least one compound selected from Group I and at least one compound selected from Group II.

9. A method as in claim 3 wherein said at least one compound comprises at least one compound selected from Group I and at least one compound selected from Group II.

10. A method as in claim 1 wherein said at least one compound comprises at least one compound selected from each of Groups I-IV.

11. A method as in claim 2 wherein said at least one compound comprises at least one compound selected from each of Groups I-IV.

12. A method as in claim 3 wherein said at least one compound comprises at least one compound selected from each of Groups I-IV.

13. A method as in claim 1 wherein said administering step comprises administering topically.

14. A method as in claim 2 wherein said administering step comprises administering topically.

15. A method as in claim 3 wherein said administering step comprises administering topically.
