Potent and selective inhibitors of platelet-derived growth factor receptor phosphorylation. Part 4: structure–activity relationships for substituents on the quinazoline moiety of 4-[4-(N-substituted(thio)carbamoyl)-1-piperazinyl]-6,7-dimethoxyquinazoline derivatives
摘要:
Here, we investigated the structure-activity relationships of the 6,7-dimethoxyquinazoline moiety. With regard to exploration of positions and varieties of substituents on the quinazoline ring, 6,7-dialkoxy substitution was optimal. This study suggests the possibility of further modifications for this moiety. (C) 2003 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.
