Novel pyrrolo[2,1-f][1,2,4]triazin-4-amines: Dual inhibitors of EGFR and HER2 protein tyrosine kinases
摘要:
A novel series of 5-((4-aminopiperidin-1-yl) methyl)-pyrrolo[ 2,1-f][ 1,2,4] triazin-4-amines with small aniline substituents at the C4 position were optimized for dual EGFR and HER2 protein tyrosine kinase inhibition. Compound 81 exhibited promising oral efficacy in both EGFR and HER2-driven human tumor xenograft models. (C) 2010 Elsevier Ltd. All rights reserved.
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.
