Compounds and uses thereof in modulating amyloid beta
View Patent ↗Novel compounds, compositions, and kits are provided. Methods of modulating Aβ levels, and methods of treating a disease associated with aberrant Aβ levels are also provided.
1. A method for treating amyloidosis associated with aberrant Aβ levels,
said method comprising administering to a subject in need thereof an effective amount of a compound having a structure corresponding to Formula (VII):
(A 1 -L A1 ) 0-1 -(B 1 )-L B1 -(C 1 )-L C1 -(D 1 ) (VII)
and pharmaceutically acceptable salts thereof, wherein:
A 1 is an optionally substituted 1,3-imidazole or a 1,2,3-triazole;
B 1 is an optionally substituted phenyl or pyridyl;
C 1 is an optionally substituted thiazole;
D 1 is a substituted aryl;
L A1 is a covalent bond;
L B1 is a covalent bond; and
L C1 is an amino linker linked at the 2-position of the thiazole.
2. The method of claim 1 wherein A 1 is an optionally substituted 1,3-imidazole.
3. The method of claim 1 wherein said optionally substituted 1,3-imidazole is a methyl-substituted 1,3-imidazole.
4. The method of claim 1 wherein said methyl-substituted 1,3-imidazole is 4-methyl 1,3-imidazole.
5. The method of claim 1 wherein B 1 is an optionally substituted phenyl.
6. The method of claim 1 wherein said optionally substituted phenyl is fluoro- or methoxy-substituted phenyl.
7. The method of claim 1 wherein B 1 is an optionally substituted pyridyl.
8. The method of claim 1 wherein C 1 is a thiazole.
9. The method of claim 1 wherein D 1 is a di- or tri-alkyl substituted phenyl.
10. The method of claim 1 wherein D 1 is 2,4-dimethyl-5-ethyl phenyl or 2-methyl-4-methoxy-5-isopropyl phenyl.
11. The method of claim 1 wherein said amyloidosis is a condition in which deposition of amyloid in the brain or periphery is a characteristic.
12. The method of claim 11 wherein said amyloidosis is associated with rheumatic diseases, idiopathic diseases, inherited conditions, inflammatory conditions, infectious diseases and malignancies.
13. The method of claim 11 wherein said amyloidosis is associated with Alzheimer's disease, Down's syndrome, HCHWA-D, familial amyloid polyneuropathy, familial amyloid cardiomyopathy (Danish type), isolated cardiac amyloid, amyloid angiopathy, systemic senile amyloidosis, familial systemic amyloidosis, light-chain amyloidosis (AL), dialysis-associated amyloidosis, renal amyloidosis, prion-related encephalopathies, spinal and spinobulbar muscular atrophy, atrial amyloidosis or pituitary amyloidosis.
14. The method of claim 1 wherein said amyloidosis is associated with Alzheimer's disease.
15. The method of claim 1 wherein said amyloidosis is associated with Down's syndrome.
16. The method of claim 1 wherein said amyloidosis is associated with diffuse Lewy body disease.
17. The method of claim 1 wherein said amyloidosis is associated with cerebral amyloid angiopathy (CAA).
18. The method of claim 1 wherein said amyloidosis is associated with systemic senile amyloidosis.
19. The method of claim 1 wherein said amyloidosis is associated with a prion-related encephalopathy.
20. The method of claim 1 wherein said amyloidosis is associated with mild cognitive impairment (MCI).
21. A method for treating a disease selected from Alzheimer's disease, Down's syndrome, HCHWA-D, familial amyloid polyneuropathy, familial amyloid cardiomyopathy (Danish type), isolated cardiac amyloid, amyloid angiopathy, systemic senile amyloidosis, familial systemic amyloidosis, light-chain amyloidosis (AL), dialysis-associated amyloidosis, renal amyloidosis, prion-related encephalopathies, spinal and spinobulbar muscular atrophy, atrial amyloidosis or pituitary amyloidosis,
said method comprising administering to a subject in need thereof an effective amount of a compound having a structure corresponding to Formula (VII):
(A 1 -L A1 ) 0-1 -(B 1 )-L B1 -(C 1 )-L C1 -(D 1 ) (VII)
and pharmaceutically acceptable salts thereof, wherein:
A 1 is an optionally substituted 1,3-imidazole or a 1,2,3-triazole;
B 1 is an optionally substituted phenyl or pyridyl;
C 1 is an optionally substituted thiazole;
D 1 is a substituted aryl;
L A1 is a covalent bond;
L B1 is a covalent bond; and
L C1 is an amino linker linked at the 2-position of the thiazole.
