HETEROCYCLIC INHIBITORS OF KINASES

摘要

The present invention provides compounds of formula (I) and pharmaceutically acceptable salts thereof. The formula (I) compounds inhibit the tyrosine kinase activity of growth factor receptors such as VEGFR-2, FGFR-1, thereby making them useful as anti-cancer agents. The formula (I) compounds are also useful for the treatment of other diseases associated with signal transduction pathways operating through growth factor receptors.
