Compositions and methods for treating cancers
The present invention relates to compositions and methods for treating of cancer. In some embodiments, the invention relates to the use of agents that can modulate a component in the CDX2-KLF4 signaling pathway to treat myelodysplastic syndromes (MDS), acute myelogenous leukemia (AML), acute lymphocytic leukemia (ALL), adult T-cell leukaemia (ATLL), lymphoma, gastric cancer, multiple myeloma, or combinations thereof, or a condition associated with abnormal activity of the CDX2-KLF4 signaling pathway.
1. A method of treating a myelodysplastic syndrome (MDS) in a human subject, comprising administering to a human subject identified as suffering from a MDS an effective amount of a compound or a pharmacologically acceptable salt or solvate thereof, said compound having formula I:
wherein
R 1 is C1-C4 alkyl; and
R 2 is halogen.
2. The method of claim 1 , wherein the human subject has an ineffective production of myeloid blood cells.
3. The method of claim 1 , wherein the human subject has an anemia.
4. The method of claim 1 , wherein the human subject has low blood counts caused by bone marrow failure.
5. The method of claim 1 , wherein R 1 is methyl, isopropyl, or t-butyl.
6. The method of claim 5 , wherein said compound has a formula selected from the group consisting of
7. The method of claim 5 , wherein said compound has formula II:
8. The method of claim 1 , wherein said human subject has one or more symptoms of MDS.
9. The method of claim 1 , wherein said MDS is high-risk MDS.
10. The method of claim 1 , wherein said compound is administered as part of a combination therapy.
11. The method of claim 10 , wherein the combination therapy comprises radiotherapy.
12. The method of claim 10 , wherein the combination therapy comprises chemotherapy.
