Abstract

A series of 4-anilinoquinazolines with C-C multiple bond substitutions at the 6-position were synthesized and investigated for their potential to inhibit epidermal growth factor receptor (EGFR) tyrosine kinase activity. Among the compounds synthesized, alkyne 6d and allenes 7d and 7f significantly inhibited EGFR tyrosine kinase activity. These compounds inhibited EGF-mediated phosphorylation of EGFR in A431 cells, resulting in cell-cycle arrest and apoptosis induction. The C-C multiple bonds substituted at the C-6 position of the anilinoquinazoline framework were essential for the significant inhibitory activity. Compounds with long carbon chains (n=3-6), such as 6c-f, 7c-f, 11, and 12, displayed prolonged inhibitory activity.
