Abstract

Compounds and compositions that can modulate mitochondrial function in neuronal cells are provided herein, as are methods for using the compounds and compositions to treat or prevent conditions such as Alzheimer's disease. For example, compounds of Formula I, compositions containing the compounds, and methods for using the compounds and compositions are provided herein:wherein X is absent, CH2, or C(O); R1 is H, OH, CN, NO2, halo, C1-3 alkyl, C1-3 haloalkyl, C1-3 alkoxy, C1-3 haloalkoxy, C3-7 cycloalkyl, amino, C1-3 alkylamino, or di(C1-3 alkyl)amino; R2 is H or C1-6 alkyl; R3 is H, C1-6 alkyl, —C(O)(C1-3 alkyl), or —C(O)O(C1-3 alkyl); R4 is C3-10 cycloalkyl, C6-10 aryl, 5-10 membered heteroaryl, or 5-10 membered heterocycloalkyl, each optionally substituted by 1, 2, 3, or 4 independently selected R5 groups; and R5 is OH, CN, NO2, halo, C1-3 alkyl, C1-3 haloalkyl, C1-3 alkoxy, C1-3 haloalkoxy, C3-7 cycloalkyl, amino, C1-3 alkylamino, or di(C1-3 alkyl)amino.

First claim

What is claimed is:

1 . A method for treating a neurodegenerative disorder in a subject, wherein the neurodegenerative disorder is Huntington's disease, and wherein the method comprises administering to the subject a therapeutically effective amount of a compound of Formula (I):

or a pharmaceutically acceptable salt thereof,
wherein:
X is absent or selected from the group consisting of CH 2 and C(O);
R 1 is selected from the group consisting of H, OH, CN, NO 2 , halo, C 1-3 alkyl, C 1-3 haloalkyl, C 1-3 alkoxy, C 1-3 haloalkoxy, C 3-7 cycloalkyl, amino, C 1-3 alkylamino, and di(C 1-3 alkyl)amino;
R 2 is selected from the group consisting of H and C 1-6 alkyl;
R 3 is selected from the group consisting of H, C 1-6 alkyl, —C(O)(C 1-3 alkyl), and —C(O)O(C 1-3 alkyl);
R 4 is selected from the group consisting of C 3-10 cycloalkyl, C 6-10 aryl, 5-10 membered heteroaryl, and 5-10 membered heterocycloalkyl, each optionally substituted by 1, 2, 3, or 4 independently selected R 5 groups; and
R 5 is selected from the group consisting of OH, CN, NO 2 , halo, C 1-3 alkyl, C 1-3 haloalkyl, C 1-3 alkoxy, C 1-3 haloalkoxy, C 3-7 cycloalkyl, amino, C 1-3 alkylamino, and di(C 1-3 alkyl)amino.

2 . The method of claim 1 , wherein the subject is a human.

3 . The method of claim 1 , wherein X is CH 2 .

4 . The method of claim 3 , wherein R 1 is C 1-3 alkyl.

5 . The method of claim 8 , wherein R 2 is C 1-6 alkyl.

6 . The method of claim 9 , wherein R 3 is H.

7 . The method of claim 6 , wherein R 4 is unsubstituted 5-10 membered heteroaryl.

8 . The method of claim 6 , wherein R 4 is aryl and R 5 is halo or OH.

9 . The method of claim 1 , wherein the compound of Formula (I) is a compound of Formula (Ia):

or a pharmaceutically acceptable salt thereof.

10 . The method of claim 1 , wherein the compound of Formula (I) is a compound of Formula (II):

or a pharmaceutically acceptable salt thereof.
wherein:
R 1 is selected from the group consisting of H, OH, CN, NO 2 , halo, C 1-3 alkyl, C 1-3 haloalkyl, C 1-3 alkoxy, C 1-3 haloalkoxy, C 3-7 cycloalkyl, amino, C 1-3 alkylamino, and di(C 1-3 alkyl)amino;
R 2 is selected from the group consisting of H and C 1-6 alkyl;
R 3 is selected from the group consisting of H, C 1-6 alkyl, —C(O)(C 1-3 alkyl), and —C(O)O(C 1-3 alkyl);
R 4 is selected from the group consisting of C 3-10 cycloalkyl, C 6-10 aryl, 5-10 membered heteroaryl, and 5-10 membered heterocycloalkyl, each optionally substituted by 1, 2, 3, or 4 independently selected R 5 groups; and
R 5 is selected from the group consisting of OH, CN, NO 2 , halo, C 1-3 alkyl, C 1-3 haloalkyl, C 1-3 alkoxy, C 1-3 haloalkoxy, C 3-7 cycloalkyl, amino, C 1-3 alkylamino, and di(C 1-3 alkyl)amino.

11 . The method of claim 10 , wherein R 1 is C 1-3 alkyl.

12 . The method of claim 11 , wherein R 2 is C 1-6 alkyl.

13 . The method of claim 12 , wherein R 3 is H.

14 . The method of claim 13 , wherein R 4 is unsubstituted 5-10 membered heteroaryl.

15 . The method of claim 13 , wherein R 4 is aryl and R 5 is halo or OH.

16 . The method of claim 10 , wherein the compound of Formula (II) is a compound of Formula (IIa)

or a pharmaceutically acceptable salt thereof.

17 . The method of claim 1 , wherein the compound of Formula (I) is selected from the group consisting of:

or a pharmaceutically acceptable salt thereof.
