ABSTRACT:
This invention describes novel pyrazole compounds of formula IV:wherein Z1or Z2is nitrogen, Q is —S—, —O—, —N(R4)—, —C(R6′)2—, 1,2-cyclopropanediyl, 1,2-cyclobutanediyl, or 1,3-cyclobutanediyl, and R1is 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; Rxand Ryare independently selected from T—R3or L—Z—R3, or Rxand Ryare taken together with their intervening atoms to form a fused, unsaturated or partially unsaturated, 5–7 membered ring having 0–3 heteroatoms; and R2and 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.
