Claims (48)

1. A method of treating colorectal cancer in a subject in need thereof, comprising:

administering to said subject a therapeutically effective amount of a compound having the following structure:

or a pharmaceutically acceptable salt or prodrug thereof,

wherein:

E is —O—;

each of R A and R C is independently —H or —OH;

each of R D and R B is independently —H, —OH or —O—C 1-6 alkyl; and

R E is —O—C 1-6 acyl.

2. The method of claim 1 , wherein R A is —OH.

3. The method of claim 1 , wherein said compound has the structure:

wherein:

each of R B and R D is independently —OH or —O—C 1-6 alkyl; and

R E is —O—C(O)-Me.

4. The method of claim 3 , wherein each of R B and R D is —OH.

5. The method of claim 3 , wherein each of R B and R D is independently —O—C 1-6 alkyl.

6. The method of claim 3 , wherein each of R B and R D is independently —O—C 1-3 alkyl.

7. The method of claim 3 , wherein each of R B and R D is —O-Me.

8. The method of claim 1 , wherein said compound has the structure:

wherein:

R A is —OH;

R C is —H or —OH; and

R E is —O—C 1-6 acyl.

9. The method of claim 8 , wherein R C is —OH and R E is —O—C(O)Me.

10. The method of claim 1 , wherein said compound has the structure:

11. A method of treating lung cancer in a subject in need thereof, comprising:

administering to said subject a therapeutically effective amount of a compound having the following structure:

or a pharmaceutically acceptable salt or prodrug thereof,

wherein:

E is —O—;

each of R A and R C is independently —H or —OH;

each of R D and R B is independently —H, —OH or —O—C 1-6 alkyl; and

R E is —O—C 1-6 acyl.

12. The method of claim 11 , wherein R A is —OH.

13. The method of claim 11 , wherein said compound has the structure:

wherein:

each of R B and R D is independently —OH or —O—C 1-6 alkyl; and

R E is —O—C(O)-Me.

14. The method of claim 13 , wherein each of R B and R D is —OH.

15. The method of claim 13 , wherein each of R B and R D is independently —O—C 1-6 alkyl.

16. The method of claim 13 , wherein each of R B and R D is independently —O—C 1-3 alkyl.

17. The method of claim 13 , wherein each of R B and R D is —O-Me.

18. The method of claim 11 , wherein said compound has the structure:

wherein:

R A is —OH;

R C is —H or —OH; and

R E is —O—C 1-6 acyl.

19. The method of claim 18 , wherein R C is —OH and R E is —O—C(O)Me.

20. The method of claim 11 , wherein said compound has the structure:
