The present invention provides compounds for modulating protein kinase enzymatic activity for modulating cellular activities such as proliferation, differentiation, programmed cell death, migration and chemoinvasion. More specifically, the invention provides appropriately functionalized 5,6-fused bicyclics which inhibit, regulate and/or modulate kinase receptor, particularly c-Met, KDR, and flt-3, signal transduction pathways related to the changes in cellular activities as mentioned above, compositions which contain these compounds, and methods of using them to treat kinase-dependent diseases and conditions.
A compound for modulating kinase activity according to Formula I,
or a pharmaceutically acceptable salt thereof, Wherein J1, J2, J3, R2, J4, Z, Ar and R3 are as defined in the specification, compositions thereof, and methods of use thereof.
