Design, Synthesis and Antitumor Activities of Novel Quinazolinone Derivatives as Potential EGFR Inhibitors.

Human epidermal growth factor (EGFR) is an important target for antitumor drug research. A series of novel quinazolinone derivatives were synthesized and developed as potent inhibitors of EGFR. The results showed that most of the aimed compounds had potential anti-tumor cell proliferation activities. Some compounds were tested for their EGFR inhibitory activity. Especially, compound 6d showed the most potent antitumor activity with IC values of 1.58 µM against human breast cancer (MCF-7) cell lines and exhibited the most potent EGFR inhibitory activity with IC of 0.77 µM. Docking simulation was performed to position compound 6d into the EGFR active site to determine the probable binding conformation.
