PYRROLOTRIAZINE COMPOUNDS AS KINASE INHIBITORS

摘要

The present invention provides compounds of formula (I); and pharmaceutically acceptable salts thereof. The formula (I) compounds inhibit tyrosine kinase activity of growth factor receptors such as HER1, HER2 and HER4 thereby making them useful as antiproliferative agents. The formula (I) compounds are also useful for the treatment of other diseases associated with signal transduction pathways operating through growth factor receptors.
