Provided herein are compounds that inhibit the phosphorylation of MAPK and thus are useful in compositions and methods for treating cancer and inflammatory disease.
1. A compound of Formula VIb1:
or a pharmaceutically acceptable salt thereof,
wherein R 1b1 is 2-pyridyl;
R 8b1 is H;
R 9b1 is substituted phenyl, heteroaryl, heterocyclyl, C(O)NR 6 R 7 , wherein the heteroaryl group is not a substituted pyrazole;
R 6 and R 7 are independently selected from hydrogen, alkyl, alkenyl, alkynyl, aryl, heteroaryl, heterocyclyl, cycloalkyl, or R 6 and R 7 are combined to form a heteroaryl or heterocyclyl structure including the nitrogen atom to which they are both attached;
wherein heteroaryl is a monocyclic or multicyclic aromatic ring system of 5 to 15 members where one to three of the atoms in the ring system is nitrogen, oxygen or sulfur; and
wherein heterocyclyl is a monocyclic or multicyclic non-aromatic ring system of 3 to 10 members where one to three of the atoms in the ring system is nitrogen, oxygen or sulfur.
2. A method of treating cancer, comprising administering to a subject a compound or a pharmaceutically acceptable salt thereof of claim 1 , wherein the cancer is a solid tumor, and wherein the solid tumor is hepatocellular carcinoma, prostate cancer, pancreatic cancer, ovarian cancer, or glioblastoma.
