Malignant
tumor is one of the major diseases that seriously threaten human health today.
Compared with traditional chemotherapy, targeted drug therapy has become a new
idea of tumor therapy. And EGFR (epidermal growth factor receptor) is highly
expressed in many human tumor cell lines, which is a biomarker of tumor
proliferation. In this paper, small molecule tyrosine kinase inhibitors with
quinazoline structure aiming at EGFR were studied. A series of novel quinazoline
derivatives (
4a~4l) have been
designed and synthesized from 4-hydroxyquinazoline as the parent core.
Structures of target compounds were characterized by
1H NMR and
13C
NMR spectra. The
in vitro anticancer
activity of compounds
4a~4l was evaluated by MTT assay against Hela, MCF-7 and A549 tumor cell lines, and
apoptosis-inducing capacity was investigated by Annexin-V/PI staining assay.
The results showed that all compounds had good antitumor activity against the
test tumor cell lines. Especially, compound
4a exhibited the best anticancer activity (IC
50 = 10.23
μM) against Hela cell lines, remarkable ability to
induce apoptosis, and low toxicity, which identified
4a as a promising anticancer drug aiming at EFGR.
