The overexpression of EGFR correlates with rapidly progressive disease, resistance to chemotherapy and poor prognosis. In certain human cancers, P13K works synergistically with EGFR to promote proliferation, survival, invasion and metastasis. Development of dual-target drugs against EGFR and P13K has therapeutic advantage and was an attractive approach against tumors. In this work, based on the molecular docking and previous studies, a series of 4-aminoquinazolines derivatives containing 6-sulfonamide substituted pyridyl group were rationally designed and identified as potent EGFR and P13K dual inhibitors. The cytotoxicity experiment results showed that this series of compounds could effectively inhibit cell growth. The kinase assay demonstrated that 6c and 6i had high inhibition for EGFR and selectivity for PI3K alpha distinguished from other isoforms. Further experiments showed that 6c could induce cell cycle arrest in G1 phase and apoptosis in BT549 cells. The western blot assay indicated that 6c inhibited the proliferation of BT549 cell through EGFR and PI3Kat/Akt signaling pathway. Our study suggested that compound 6c was a potential dual inhibitors of EGFR and PI3K alpha. (C) 2018 Elsevier Masson SAS. All rights reserved.
