Definitions

• the present invention relates to fused pyrazoles, to methods of making the compounds, to compositions containing the compounds, and to methods of treatment using the compounds.
• Protein kinases are important in the progression of many disease states that are induced by the inappropriate proliferation of cells. These kinases are often found to be up-regulated in many hyperproliferative states such as cancer. These kinases may also be important in cell signaling, where their inappropriate activation induces cells to proliferate (e.g., EGFR, ERBB2, VEGFR, FGFR, PDGFR, c-Met, IGF-lR, RET, TBE2). Alternatively, kinases may be involved in signal transduction within cells (e.g., c-Src, PKC, Akt, PKA, c-Abl, PDK-1) where these signal transduction genes are recognized proto-oncogenes.
• kinases control cell cycle progression near the Gl-S transition (e.g., Cdk2, Cdk4), at the G2-M transition (e.g., Weel, Mytl, Chkl, Cdc2) or at the spindle checkpoint (Plk, Auroral or 2, Bubl or 3).
• kinases are intimately linked to the DNA damage response (e.g., ATM, ATR, Chkl, Chk2).
• Deregulation of these cellular functions: cell signaling, signal transduction, cell cycle control, and DNA repair are all hallmarks of hyperproliferative diseases, particularly cancer. Therefore, pharmacological modulation of one or more kinases would be useful in slowing or stopping diseases that are induced by the inappropriate proliferation of cells such as cancer.
