Abstract: This invention describes novel pyrazole compounds of formula I′:
wherein Q′ is —O—, —C(R6′)2—, 1,2-cyclopropanediyl, 1,2-cyclobutanediyl, or 1,3-cyclopropanediyl, and 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; Rx and Ry are independently selected from T—R3 or L—Z—R3, or Rx and Ry are taken together with their intervening atoms to form a fused, unsaturated or partially unsaturated, 5-7 membered ring having 0-3 heteroatoms; and 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.
