Benzazole compounds and methods for making and using the compounds
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.
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.
