Use of delta tocopherol for the treatment of lysosomal storage disorders
View Patent ↗This disclosure relates generally to the treatment of lysosomal storage disorders. Specifically, the disclosure relates to a novel use of δ tocopherol in the treatment of diseases and conditions related to lysosomal storage disorders. Included in the present disclosure is a method for the modulation of cholesterol recycling. Further, the disclosure relates to conditions such as Niemann-Pick type C disease, Farber disease, Niemann-Pick type A disease, Wolman disease and Tay Sachs disease. Further included in the present disclosure is a method for treating lysosomal storage disorders comprising the administration of δ tocopherol. Further included in the present disclosure is a method for treating lysosomal storage disorders comprising the administration of δ tocopherol in combination with cyclodextrin to a patient in need thereof.
1. A method for treating a lysosomal storage disorder comprising administering to a subject in need thereof (i) a therapeutically and synergistically effective amount of δ tocopherol; and (ii) a therapeutically and synergistically effective amount of cyclodextrin.
2. The method of claim 1 , wherein the lysosomal storage disorder is selected from the group consisting of Niemann-Pick Type C disease, Niemann-Pick Type A disease, Wolman disease, Farber disease, and Tay Sachs disease.
3. The method of claim 2 , wherein the lysosomal storage disorder is Niemann-Pick Type C Disease.
4. The method of claim 1 , wherein the cyclodextrin is 2-hydroxypropyl-beta-cyclodextrin.
5. The method of claim 1 , wherein the subject is human.
6. The method of claim 1 , wherein the δ tocopherol is administered in a dosage resulting in a plasma concentration of 10 μM to 50 μM.
7. The method of claim 1 , wherein the δ tocopherol is administered in a dosage of less than 1000 IU/kg per day.
8. The method of claim 1 , wherein each of the δ tocopherol and the cyclodextrin is administered by a route independently selected from the group consisting of oral, topical, suppository, intravenous, intradermic, intragaster, intramuscular, intraperitoneal, intrathecal, and intracerebroventricular administration.
9. The method of claim 1 , further comprising administering at least one inhibitor of CYP4F2.
10. The method of claim 9 , wherein the inhibitor is selected from the group consisting of ketoconazole, sesame seeds, lignan sesamin, and lignan sesaminol.
11. A method for reducing cholesterol accumulation in cells comprising administering to a subject in need thereof (i) a therapeutically and synergistically effective amount of δ tocopherol; and (ii) a therapeutically and synergistically effective amount of cyclodextrin.
12. The method of claim 11 , wherein the cholesterol to be reduced is free cholesterol.
13. The method of claim 11 , wherein the cholesterol accumulation is observed in lysosomes of the cells.
14. The method of claim 11 , wherein the cyclodextrin is 2-hydroxypropyl-beta-cyclodextrin.
15. The method of claim 11 , wherein the subject is human.
16. The method of claim 11 , wherein the δ tocopherol is administered in a dosage resulting in a plasma concentration of 10 μM to 50 μM.
17. The method of claim 11 , wherein the δ tocopherol is administered in a dosage of less than 1000 IU/kg per day.
18. The method of claim 11 , wherein each of the δ tocopherol and the cyclodextrin is administered by a route independently selected from the group consisting of oral, topical, suppository, intravenous, intradermic, intragaster, intramuscular, intraperitoneal, intrathecal, and intracerebroventricular administration.
19. The method of claim 11 , further comprising administering at least one inhibitor of CYP4F2.
20. The method of claim 19 , wherein the inhibitor is selected from the group consisting of ketoconazole, sesame seeds, lignan sesamin, and lignan sesaminol.
