  6-Oxooxazolidine–quinazolines as noncovalent inhibitors with the potential to target mutant forms of EGFR

  摘要：

  Despite the remarkable benefits of gefitinib, the clinical efficacy is eventually diminished due to the acquired point mutations in the EGFR (T790M). To address this unmet medical need, we demonstrated a strategy to prepare a hybrid analogue consisting of the oxooxazolidine ring and the quinazoline scaffold and provided alternative noncovalent inhibitors targeting mutant forms of EGFR. Most of the derivatives displayed moderate to good anti-proliferative activity against gefitinib-resistant NCI-H1975. Some of them exhibited potent EGFR kinase inhibitory activities, especially on EGFR(T790M) and EGFR(L858R) kinases. SAR studies led to the identification of a hit 9a that can target both of the most common EGFR mutants: L858R and T790M. Also, 9a displayed weaker inhibitory against cancer cell lines with low level of EGFR expression and good chemical stability under different pH conditions. The work presented herein showed the potential for developing noncovalent inhibitors targeting EGFR mutants. (C) 2016 Published by Elsevier Ltd.
