Claims (43)

1. A compound of Formula (III):

or a pharmaceutically acceptable salt thereof, wherein:

R 1 and R 2 are independently chosen from hydrogen, C 1-6 alkyl, and substituted C 1-6 alkyl; and

R 3 and R 4 independently chosen from hydrogen, C 1-6 alkyl, substituted C 1-6 alkyl, C 1-6 heteroalkyl, substituted C 1-6 heteroalkyl, C 4-12 cycloalkylalkyl, substituted C 4-12 cycloalkylalkyl, C 7-12 arylalkyl, and substituted C 7-12 arylalkyl; or R 3 and R 4 together with the nitrogen to which they are bonded form a ring chosen from a C 5-10 heteroaryl, substituted C 5-10 heteroaryl, C 5-10 heterocycloalkyl, and substituted C 5-10 heterocycloalkyl; and

wherein each substituent group is independently chosen from halogen, —OH, —CN, —CF 3 , ═O, —NO 2 , benzyl, —C(O)NR 11 2 , —R 11 , —OR 11 , —C(O)R 11 , —COOR 11 , and —NR 11 2 wherein each R 11 is independently chosen from hydrogen and C 1-4 alkyl.

2. The compound of claim 1 , wherein each of R 1 and R 2 is hydrogen.

3. The compound of claim 1 , wherein one of R 1 and R 2 is hydrogen and the other of R 1 and R 2 is chosen from methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, and sec-butyl.

4. The compound of claim 1 , wherein R 3 and R 4 are independently chosen from hydrogen and C 1-6 alkyl.

5. The compound of claim 1 , wherein R 3 and R 4 together with the nitrogen to which they are bonded form a C 5-10 heterocycloalkyl ring.

6. The compound of claim 1 , wherein one of R 1 and R 2 is hydrogen and the other of R 1 and R 2 is chosen from hydrogen and C 1-6 alkyl; and R 3 and R 4 together with the nitrogen to which they are bonded form a ring chosen from morpholine, piperazine, and N-substituted piperazine.

7. The compound of claim 1 , wherein one of R 1 and R 2 is hydrogen; and the other of R 1 and R 2 is chosen from hydrogen and C 1-6 alkyl; R 3 is hydrogen; R 4 is chosen from hydrogen, C 1-6 alkyl, and benzyl.

8. The compound of claim 1 , wherein the compound is chosen from:
