Caffeinated compounds and compositions for treatment of amyloid diseases and synucleinopathies
View Patent ↗Compounds and their pharmaceutically acceptable salts for treatment of β-amyloid diseases, such as observed in Alzheimer's disease and synucleinopathies, such as Parkinson's disease.
1. A compound selected from the group consisting of compounds of the formula
where:
R 1-3 are independently substituted with hydrogen, methyl and benzyl groups, wherein at least two of R 1-3 are benzyl substituted at any one time, and
wherein the benzyl groups are substituted with two hydroxy groups,
and pharmaceutically acceptable salts thereof.
2. The compound a claim 1 selected from the group consisting of:
3. A pharmaceutical composition comprising the compound of claim 1 and a pharmaceutically acceptable excipient.
4. A method of treating the formation, deposition, accumulation, or persistence of amyloid or α-synuclein fibrils, comprising treating the fibrils with an effective amount of the compound of claim 1 .
5. A method of inhibiting the formation, deposition, accumulation, or persistence of amyloid or α-synuclein fibrils in a mammal suffering from an amyloid disease or a synucleinopathy, comprising administration of a therapeutically effective amount of the compound of claim 1 .
6. The method of claim 5 where the amyloid disease is selected from the group of diseases consisting of Alzheimer's disease, type II diabetes, systemic AA amyloidosis, Down's syndrome, hereditary cerebral hemorrhage with amyloidosis of the Dutch type, and cerebral β-amyloid angiopathy.
7. The method of claim 5 where the amyloid disease is Alzheimer's disease.
8. The method of claim 5 where the synucleinopathy is selected from the group consisting of Parkinson's disease, familial Parkinson's disease, Lewy body disease, the Lewy body variant of Alzheimer's disease, dementia with Lewy bodies, multiple system atrophy, and the Parkinsonism-dementia complex of Guam.
9. The method of claim 5 where the synucleinopathy is Parkinson's disease.
10. The method of claim 5 , where the compound administered is in an amount between 0.1 mg/Kg/day and 1000 mg/Kg/day.
11. The method of claim 5 , where the compound is administered in an amount between 1 mg/Kg/day and 100 mg/Kg/day.
12. The Method of claim 5 , where the compound administered is in an amount between 10 mg/Kg/day and 100 mg/Kg/day.
13. An article of manufacture, comprising packaging material, the compound of claim 1 , or a pharmaceutically acceptable salt thereof, contained within packaging material, which is used for treating the formation, deposition, accumulation, or persistence of β-amyloid or α-synuclein and/or aggregates, and a label that indicates that the compound or pharmaceutically acceptable salt thereof is used for treating the formation, deposition, accumulation, or persistence of β-amyloid or α-synuclein fibrils and/or aggregates.
