Claims (19)

1 . A pharmaceutical composition comprising a compound represented by structural formula IV:

or a pharmaceutically acceptable salt thereof, wherein:

R 2 is selected from optionally substituted heteroaryl and a pharmaceutically acceptable carrier.

2 . The pharmaceutical composition of claim 1 , wherein R 2 is an optionally substituted 5-6-membered heteroaryl having 1, 2 or 3 heteroatoms independently selected from the group consisting of nitrogen, oxygen and sulfur.

3 . The pharmaceutical composition of claim 2 , wherein R 2 is an optionally substituted 5-membered heteroaryl having 1, 2 or 3 heteroatoms independently selected from the group consisting of nitrogen, oxygen and sulfur.

4 . The pharmaceutical composition of claim 3 , wherein R 2 is an optionally substituted pyrrolyl, furanyl, thiophenyl, pyrazolyl, imidazolyl, thiazolyl, isothiazolyl, oxazolyl, isoxazolyl, triazolyl, thiadiazolyl, or oxadiazolyl.

5 . The pharmaceutical composition of claim 2 , wherein R 2 is an optionally substituted 6-membered heteroaryl having 1, 2 or 3 heteroatoms independently selected from the group consisting of nitrogen, oxygen and sulfur.

6 . The pharmaceutical composition of claim 5 , wherein R 2 is an optionally substituted pyridinyl, pyrimidinyl, pyrazinyl, pyridazinyl or triazinyl.

7 . The pharmaceutical composition of claim 1 , wherein R 2 is optionally substituted with 1, 2 or 3 substituents independently selected from halogen, C 1 -C 4 alkyl, halo-C 1 -C 4 alkyl, C 1 -C 4 alkoxy, C 1 -C 4 thioalkoxy, hydroxyl, amino, C 1 -C 4 alkylamino, C 1 -C 4 dialkylamino, sulfhydryl, cyano, C 6 aryl and C 5 -C 6 heteroaryl.

8 . The pharmaceutical composition of claim 7 , wherein R 2 is optionally substituted with 1, 2 or 3 substituents independently selected from fluoro, chloro, C 1 -C 4 alkyl, —CF 3 , amino and cyano.

9 . A method for treating a cancer, the method comprising administering to a subject in need thereof a therapeutically effective amount of a pharmaceutical composition of claim 1 , wherein the cancer is selected from multiple myeloma, diffuse large B-cell lymphoma, acute myeloid leukemia and follicular lymphoma.

10 . A method for promoting wound healing in a subject in need thereof, comprising administering to the subject in need thereof a therapeutically effective amount of a pharmaceutical composition of claim 2 .

11 . The method of claim 9 , wherein the cancer is multiple myeloma.

12 . The method of claim 9 , wherein the cancer is diffuse large B-cell lymphoma.

13 . The method of claim 9 , wherein the pharmaceutical composition is administered orally.

14 . A method for treating a cancer, the method comprising administering to a subject in need thereof a therapeutically effective amount of a pharmaceutical composition of claim 2 , wherein the cancer is prostate cancer.

15 . The method of claim 14 , wherein the pharmaceutical composition is administered orally.

16 . A method for treating myelodysplastic syndrome, the method comprising administering to a subject in need thereof a therapeutically effective amount of a pharmaceutical composition of claim 1 .
