title: New substituted 4-arylaminoquinazolines as potent inhibitors of breast tumor cell lines: in vitro and docking experiments.
abstract: The arylquinazolines represent significant advances in the clinical management of breast cancer. Nevertheless some confirmatory studies must be considered to foster the use of anti-EGFR therapies including safety and clinical use. Two 4-arylaminoquinazoline derivatives, recently synthesized, were tested as kinase inhibitors and their citotoxicities showed potent growth inhibitory activity in breast tumor cell lines (MCF-7). The predicted complex structure of quinazoline inhibitors with EGFR protein from molecular docking provided a stereoview of the binding site correlated with structure activity, affording important information about structure-based drug design.
