Fifteen new iodoquinazoline derivatives, 5a,b to 18, are reported in this study and their anticancer evaluation as dual inhibitors of EGFR and EGFR . The new derivatives were designed according to the target of structural requirements of receptors. Cytotoxicity of our compounds was evaluated against MCF-7, A549, HCT116 and HepG2 cell lines using MTT assay. Compounds 18, 17 and 14b showed the highest anticancer effects with IC = 5.25, 6.46, 5.68 and 5.24 μM, 5.55, 6.85, 5.40 and 5.11 μM and 5.86, 7.03, 6.15 and 5.77 μM against HepG2, MCF-7, HCT116 and A549 cell lines, respectively. The eight highly effective compounds 10, 13, 14a, 14b, 15, 16, 17 and 18 were inspected against VERO normal cell lines to evaluate their cytotoxicity. Our conclusion was that compounds 10, 13, 14a, 14b, 15, 16, 17 and 18 possessed low toxicity against VERO normal cells with IC increasing from 43.44 to 52.11 μM. All compounds were additionally assessed for their EGFR and EGFR inhibitory activities. Additionally, their ability to bind with EGFR and EGFR receptors was confirmed by molecular docking. Compound 17 exhibited the same inhibitory activity as erlotinib. Compounds 10, 13, 14b, 16 and 18 excellently inhibited VEGFR-2 activity with IC ranging from 0.17 to 0.50 μM. Moreover, compounds 18, 17, 14b and 16 remarkably inhibited EGFR activity with IC = 0.25, 0.30, 0.36 and 0.40 μM respectively. As planned, compounds 18, 17 and 14b showed excellent dual EGFR /EGFR inhibitory activities. Finally, our compounds 18, 17 and 14b displayed good ADMET calculated profiles.
