DOT1L INHIBITORS FOR USE IN THE TREATMENT OF LEUKEMIA
The present invention relates to DOT1L inhibitors. The present invention also relates to pharmaceutical compositions containing these compounds and methods of treating disorders in which DOT1-mediated protein methylation plays a part, such as cancer, by administering these compounds and pharmaceutical compositions to subjects in need thereof.
1 . A method for treating or alleviating a symptom of leukemia comprising administering to a subject in need thereof a therapeutically effective amount of a compound listed in any of Tables 1-4.
2 . The method of claim 1 , wherein said leukemia is characterized by a chromosomal rearrangement.
3 . The method of claim 2 , wherein said chromosomal rearrangement is chimeric fusion of mixed lineage leukemia gene (MLL) or partial tandem duplication of MLL (MLL-PTD).
4 . The method of claim 1 , wherein said subject has an increased level of HOXA9, Fms-like tyrosine kinase 3 (FLT3), MEIS1, and/or DOT1L.
5 . A method for treating or alleviating a symptom of leukemia comprising administering to a subject in need thereof a therapeutically effective amount of a compound listed in any of Tables 1-4, wherein the subject has an increased level of HOXA9, FLT3, MEIS1, and/or DOT1L.
6 . A method for treating or alleviating a symptom of leukemia in a subject comprising
1) obtaining a sample from the subject;
2) detecting the level of HOXA9, FLT3, MEIS1, and/or DOT1L, wherein an increased level of HOXA9, FLT3, MEIS1, and/or DOT1L indicates the subject is responsive to a compound listed in any of Tables 1-4; and
3) administering to the subject a therapeutically effective amount of said compound when said subject is responsive to said compound.
7 . A method for treating or alleviating a symptom of leukemia in a subject comprising
1) obtaining a sample from the subject;
2) detecting the presence of a genetic lesion of MLL in the sample; and
3) administering to the subject a therapeutically effective amount of a compound listed in any of Tables 1-4 when said genetic lesion is present in the sample.
8 . The method of claim 5 , wherein said sample is selected from bone marrow, peripheral blood cells, blood, plasma, serum, urine, saliva, a cell, or a tumor tissue.
9 . The method of claim 7 , wherein said genetic lesion is chimeric fusion of MLL or MLL-PTD.
10 . A method for treating a disorder mediated by translocation, deletion and/or duplication of a gene on chromosome 11q23, comprising administering to a subject in need thereof a therapeutically effective amount of a compound listed in any of Tables 1-4.
11 . The method of claim 1 , wherein said compound is Compound A2.
12 . The method of claim 1 , wherein said compound is Compound D16.
13 . The method of claim 6 , wherein said compound is Compound A2.
14 . The method of claim 6 , wherein said compound is Compound D16.
15 . The method of claim 7 , wherein said compound is Compound A2.
16 . The method of claim 7 , wherein said compound is Compound D16.
17 . The method of claim 10 , wherein said compound is Compound A2.
18 . The method of claim 10 , wherein said compound is Compound D16.
19 . The method of claim 7 , wherein said sample is selected from bone marrow, peripheral blood cells, blood, plasma, serum, urine, saliva, a cell, or a tumor tissue.
