Discovery of novel quinazoline derivatives bearing semicarbazone moiety as potent EGFR kinase inhibitors

Computational and Structural Biotechnology Journal, 2018
Aimed at discovering effective EGFR inhibitors, six series of quinazoline derivatives bearing a semicarbazone moiety were designed, synthesized and evaluated in different cancer cell lines (A549, HepG2, MCF-7 and PC-3).
