Abstract
This invention describes novel pyrazole compounds of formula II: 1 wherein Z1 is nitrogen or CR8; Q is —S—, —O—, —N(R4)—, or —CH(R6)—; R1 is T-Ring D, wherein Ring D is a 5-7 membered monocyclic ring or 8-10 membered bicyclic ring selected from aryl, heteroaryl, heterocyclyl or carbocyclyl; and Ry, R2, and R2′ are as described in the specification. The compounds are useful as protein kinase inhibitors, especially as inhibitors of Aurora-2 and GSK-3, for treating diseases such as cancer, diabetes and Alzheimer's disease.
