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 quinazolines and
quinolines which inhibit, regulate, and/or modulate kinase receptor,
particularly c-Met, KDF, c-Kit, flt-3 and flt-4, 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. The present
invention also provides methods for making compounds as mentioned above,
and compositions which contain these compounds.
