  • Title: Discovery of novel 4-anilinoquinazoline derivatives as potent inhibitors of epidermal growth factor receptor with antitumor activity.

    Journal: Bioorg Med Chem; 2013 Oct 01; 21(19):6084-91. PubMed ID: 23962660.
    Abstract:
    Two new series of new compounds containing a 6-amino-substituted group or 6-acrylamide-substituted group linked to a 4-anilinoquinazoline nucleus have been discovered as potential EGFR inhibitors. These compounds proved efficient effects on antiproliferative activity and EGFR-TK inhibitory activity. Especially, N(6)-((5-bromothiophen-2-yl)methyl)-N(4)-(3-chlorophenyl)quinazoline-4,6-diamine (5e), showed the most potent inhibitory activity (IC50=3.11μM for Hep G2, IC50=0.82μM for A549). The EGFR molecular docking model suggested that the new compound is nicely bound to the region of EGFR, and cell morphology by Hoechst stain experiment suggested that these compounds efficiently induced apoptosis of A549 cells.
