Abstract

Disclosed are novel benzazole compounds and compositions comprising the compounds. The compounds are useful as kinase inhibitors including interleukin receptor associated kinases (IRAK) inhibitors. Also disclosed are methods of making and using the compounds and compositions. The disclosed compounds and/or compositions may be used to treat or prevent an IRAK-associated disease or condition.

Claims (32)

1. A method of treating a hematological malignancy in a subject, comprising administering to the subject an effective amount of a compound having a formula

or a pharmaceutically acceptable salt thereof, wherein:

X is O or S;

Het-1 is heterocyclyl;

R 1 and R 2 independently are H, aliphatic, heteroaliphatic, heterocyclyl, aryl, araliphatic, or together with the nitrogen to which they are attached, form a heterocyclic ring;

R 3 , R 4 , R 5 , R 6 and R 9 independently are H, aliphatic, halo, heteroaliphatic, —O-aliphatic, heterocyclyl, aryl, araliphatic, —O-heterocyclyl, hydroxyl, nitro, cyano, carboxyl, carboxyl ester, acyl, amide, amino, sulfonyl, sulfonamide, sulfanyl, sulfinyl or haloalkyl;

R 7 is H, aliphatic, heteroaliphatic, heterocyclyl, aryl or araliphatic;

each R 8 independently is aliphatic, halo, heteroaliphatic, —O-aliphatic, heterocyclyl, aryl, araliphatic, —O-heterocyclyl, hydroxyl, nitro, cyano, carboxyl, carboxyl ester, acyl, amide, amino, sulfonyl, sulfonamide, sulfanyl, sulfinyl or haloalkyl; and

m is from 0 to 3;

wherein treating the hematological malignancy comprises slowing the development of the malignancy, stabilizing the malignancy, or causing regression of the malignancy or a symptom thereof.

2. The method of claim 1 , wherein:

Het-1 is heteroaryl;

R 1 is H or alkyl, and R 2 is aliphatic or heteroaliphatic;

R 5 is amino, aryl or heteroaryl;

at least one R 8 is —NH 2 , —CH 3 , —CF 3 , —CF 2 H or —CH 2 CF 3 ; or

a combination thereof.

3. The method of claim 1 , wherein:

is selected from

R 5 is selected from

or

a combination thereof.

4. The method of claim 1 , wherein the R 1 —N—R 2 moiety is selected from

R a is aliphatic, haloalkyl or acyl;

n is 1 or 2; and

p is 0, 1 or 2.

5. The method of claim 1 , wherein the hematological malignancy is a leukemia or lymphoma.

6. The method of claim 1 , wherein the hematological malignancy is chronic lymphocytic leukemia, acute lymphocytic leukemia, B-cell prolymphocytic leukemia, cutaneous T cell lymphoma, chronic lymphocytic leukemia, pleural effusion lymphoma, smoldering or indolent multiple myeloma, lymphoplasmacytic lymphoma, myelodysplastic syndrome, myelofibrosis, polycythemia vera, diffuse large B-cell lymphoma, Hodgkins or Non-Hodgkins lymphoma, Waldenström's macroglobulinemia or Burkitt lymphoma/leukemia.

7. The method of claim 1 , further comprising administering an additional therapeutic agent.

8. The method of claim 7 , wherein the additional therapeutic agent is a B-cell lymphoma 2 (BCL2) inhibitor, a kinase inhibitor, an antibody, or a combination thereof.

9. The method of claim 8 , wherein the B-cell lymphoma 2 (BCL2) inhibitor is ABT-199 or ABT737.

10. The method of claim 8 , wherein the kinase inhibitor is a Btk inhibitor, CDK inhibitor, EGFR inhibitor, Mek inhibitor, Raf inhibitor, VEGFR inhibitor, BCR-Abl inhibitor, PI3-kinase inhibitor, Syk inhibitor, JAK inhibitor, or a combination thereof.

11. The method of claim 8 , wherein the kinase inhibitor is ibrutinib, palbociclib, afatinib, erlotinib, gefitinib, lapatinib, vandetinib, trametinib, dabrafenib, sorafenib, vemurafenib, axitinib, lenvatinib, nintedanib, pazopanib, bosutinib, dasatinib, imatinib, nilotinib, idelalisib, fostamatinib, baricitinib, ruxolitinib, tofacitinib, or a combination thereof.
