1. A compound having a structure of Formula I or a pharmaceutically acceptable salt thereof:

wherein

Z is CR 3 ;

R 1 is

optionally

substituted cycloalkyl, heterocyclyl, aryl, oxazolyl, indolyl, benzoisoxazolyl, indazolyl, azaindolyl, benzothiazolyl, imidazo[1,2-a]pyridine, or thiazolyl, wherein the optionally substituted aryl is optionally substituted phenanthrenyl or naphthalenyl substituted with one or more groups selected from hydroxyl and nitro;

R 2 is optionally substituted alkyl, cycloalkyl, heterocyclyl, aryl, or heteroaryl; and

R 3 is H or optionally substituted alkyl, carboxy or ester, provided when R 1 is cycloalkyl, aryl, heterocyclyl, or heteroaryl and R 2 is optionally substituted alkyl, R 3 is not alkyl.

2. The compound of claim 1 , wherein R 3 is

3. The compound of claim 1 , wherein R 1 is naphthalenyl substituted with one or more groups selected from hydroxyl and nitro.

4. The compound of claim 3 , wherein R 1 is selected from

5. The compound of claim 1 , wherein R 1 is selected from

6. The compound of claim 1 , wherein the oxazolyl, indolyl, benzoisoxazolyl, indazolyl, azaindolyl, benzothiazolyl, imidazo[1,2-a]pyridine, and thiazolyl is substituted with one or more groups selected from halo, oxy, nitro, sulfonate, and optionally substituted alkyl.

7. The compound of claim 1 , wherein R 1 is selected from

8. The compound of claim 1 , wherein R 2 is alkyl substituted with alkoxy, amino or optionally substituted aryl.

9. The compound of claim 1 , wherein R 2 is selected from

10. The compound of claim 1 , wherein R 2 is selected from

11. The compound of claim 1 , wherein R 2 is optionally substituted phenyl.

12. The compound of claim 11 , wherein the phenyl is substituted with one more groups selected from halo, hydroxyl, cyano, optionally substituted alkyl, optionally substituted alkoxy, carboxy, and ester.

13. The compound of claim 1 , wherein R 2 is selected from

14. A compound selected from

or a pharmaceutically acceptable salt thereof.

15. A pharmaceutical composition comprising the compound or a pharmaceutically acceptable salt thereof of claim 1 and a pharmaceutically acceptable carrier.

16. A method of treating acute myeloid leukemia, liver cancer, lung cancer, or myelodysplastic syndrome (MDS) comprising administering to a subject the compound or a pharmaceutically acceptable salt thereof of claim 1 .

17. The compound of claim 14 , which is
