Targeting EGFR/HER2 tyrosine kinases with a new potent series of 6-substituted 4-anilinoquinazoline hybrids: Design, synthesis, kinase assay, cell-based assay, and molecular docking.

Abstract:

:Coexpression of EGFR and HER2 has been found in many tumors such as breast, ovarian, colon and prostate cancers, with poor prognosis of the patients. Herein, our team has designed and synthesized new eighteen compounds with 6-substituted 4-anilinoquinazoline core to selectively inhibit EGFR/HER2 tyrosine kinases. Twelve compounds (8a-8d, 9a, 9c, 9d, 10a, 10c, 11b, 14, and 15) showed nanomolar range of IC50 values on EGFR and/or HER2 kinases. Accordingly, a detailed structure activity relationship (SAR) was established. A molecular docking study demonstrated the favorable binding modes of 8d, 9b, 9d and 10d at the ATP active site of both kinases. A kinase selectivity profile performed for compound 8d showed great selectivity for EGFR and HER2. In addition, 8d, 9c, and 9d exerted selective promising cytotoxic activity over BT-474 cell line with IC50 values of 2.70, 1.82 and 1.95 μM, respectively. From these results, we report analogs 8d, 9c, and 9d as promising candidates for the discovery of well-balanced compounds in terms of the kinase inhibitory potency and antiproliferative activity.
