Pyrazole compounds useful as protein kinase inhibitors

摘要

This invention provides novel pyrazole compounds that are useful as protein kinase inhibitors, especially as inhibitors of aurora-2 and GSK-3. The compounds may be used to treat abnormal physiological function leading to diseases such as cancer, diabetes and Alzheimer's disease. The compounds are represented by formula VI:wherein G is Ring C or Ring D; Ring C is selected from a phenyl, pyridinyl, pyrimidinyl, pyridazinyl, pyrazinyl, or 1,2,4-triazinyl ring, wherein said Ring C has one or two ortho substituents independently selected from -R<1>; Ring D is a 5-7 membered monocyclic ring or 8-10 membered bicyclic ring selected from aryl, heteroaryl, heterocyclyl or carbocyclyl; R<y >is T-R<3'>; T is a valence bond or a C1-4 alkylidene chain; R<3'> is an optionally substituted group selected from C1-6 aliphatic, C3-10 carbocyclyl, C6-10 aryl, a heteroaryl ring having 5-10 ring atoms, or a heterocyclyl ring having 5-10 ring atoms; and R<1>, R<2>, and R<2'> are as described in the specification.
