Abstract

Methods of retarding formation of a lipofuscin pigment in the retina and of treating or ameliorating the effects of a disease characterized by an accumulation of a lipofuscin pigment in a retina are provided. These methods include the step of administering to a patient in need thereof a substituted C₂₀-retinoid in an amount sufficient to reduce accumulation of a lipofuscin pigment in the retina. Further provided are methods of retarding formation of A2E and/or ATR-dimer by replacing an all-frans-retinal (ATR) substrate with a C₂₀-D₃-retinal substrate under conditions sufficient to impede the formation of A2E. Compositions for retarding formation of a lipofuscin pigment in the retina containing a substituted C₂₀-retinoid and a pharmaceutically acceptable carrier are also provided.

Claims

1. A method of retarding the accumulation of a lipofuscin pigment in a retina, comprising administering an effective amount of a pharmaceutical composition to a patient in need thereof, wherein the pharmaceutical composition comprises a substituted C₂₀-D_1-3-retinoid, wherein the C₂₀-D_1-3-retinoid is selected from the group consisting of C₂₀-D_1-3-retinol C₂₀-D_1-3-retinol ester, C₂₀-D_1-3-retinal and C₂₀-D_1-3-pro-vitamin A carotenoids, and a pharmaceutically acceptable carrier.

2. The method according to claim 1, wherein the substituted C₂₀-D_1-3-retinoid is a C₂₀-D₃-retinoid.

3. The method according to claim 1, wherein the pharmaceutical composition is suitable for use as a nutraceutical composition.

4. The method according to claim 1, wherein the patient is in need of treatment for a macular degeneration.

5. The method according to claim 4, wherein the macular degeneration is age-related macular degeneration.

6. The method according to claim 5, wherein the C₂₀-D_1-3-retinoid is C₂₀-D_1-3-retinol or a C₂₀-D_1-3-retinol ester.

7. The method according to claim 5, wherein the C₂₀-D_1-3-retinoid is C₂₀-D₃-retinol, a C₂₀-D₃-retinol ester, C₂₀-D₃-retinal, or a C₂₀-D₃-pro-vitamin A carotenoid.

8. The method according to claim 5, wherein the C₂₀-D_1-3-retinoid is C₂₀-D₃-retinol acetate.

9. The method according to claim 8, wherein the C₂₀-D₃-retinal, corresponding to the aldehyde of the C₂₀-D₃-retinol acetate, forms A2E in vitro about 7 times slower than non-deuterium-enriched retinal.

10. The method according to claim 5, wherein the patient is in need of treatment for dry (non-neovascular) age-related macular degeneration.

11. The method according to claim 1, wherein the patient is in need of treatment for Stargardt disease.

12. The method according to claim 11, wherein the C₂₀-D_1-3-retinoid is C₂₀-D_1-3-retinol or a C₂₀-D_1-3-retinol ester.

13. The method according to claim 11, wherein the C₂₀-D_1-3-retinoid is C₂₀-D₃-retinol, a C₂₀-D₃-retinol ester, C₂₀-D₃-retinal, or a C₂₀-D₃-pro-vitamin A-carotenoid.

14. The method according to claim 11, wherein the C₂₀-D_1-3-retinoid is C₂₀-D₃-retinol acetate.

15. The method according to claim 14, wherein the C₂₀-D₃-retinal, corresponding to the aldehyde of the C₂₀-D₃-retinol acetate, forms A2E in vitro about 7 times slower than non-deuterium-enriched retinal.

16. The method according to claim 1, wherein the patient is in need of treatment for a macular degeneration selected from the group consisting of Vitelliform or Best disease, Sorsby'"'"'s fundus dystrophy, retinitis pigmentosa, and Malattia Leventinese.

17. The method according to claim 16, wherein the C₂₀-D_1-3-retinoid is C₂O-D₃-retinol acetate.

18. The method according to claim 1, wherein the patient is in need of treatment for a macular degeneration characterized by one or more mutation(s) in the ABCA4 gene.

19. The method according to claim 1, wherein the substituted C₂₀-D_1-3-retinoid is present in the pharmaceutical composition at a level sufficient to deliver on average about 0.1 to about 90 mg/day to a patient.

20. The method according to claim 1, further comprising an additional active.

21. The method according to claim 20, wherein the additional active is selected from the group consisting of eye antioxidants, minerals, negatively-charged phospholipids, carotenoids, and combinations thereof.

22. The method according to claim 21, wherein the eye antioxidant is selected from the group consisting of vitamin C, vitamin E, beta-carotene, coenzyme Q, OT-551, 4-hydroxy-2,2,6,6-tetramethylpiperidine-N-oxyl, butylated hydroxytoluene, resveratrol, a trolox analogue (PNU-83836-E), bilberry extract, and combinations thereof.

23. The method according to claim 21, wherein the mineral is selected from the group consisting of cupric oxide, zinc oxide;

selenium-containing compounds, and combinations thereof.

24. The method according to claim 21, wherein the negatively charged phospholipid is selected from the group consisting of cardiolipin, phosphatidylglycerol, and combinations thereof.

25. The method according to claim 21, wherein the carotenoid is selected from the group consisting of zeaxanthin, lutein, and combinations thereof.

26. The method according to claim 1, wherein the C₂₀-D₃-retinal, corresponding to the aldehyde of the C₂₀-D₃-retinol acetate, forms A2E in vitro about 7 times slower than non-deuterium-enriched retinal.

27. The method according to claim 1, wherein the pharmaceutical composition is administered directly to the eye.
