Abstract:

A series of 6,7-dimethoxyquinazoline derivatives connected by diaryl urea scaffolds was designed, synthesized and their in vitro antitumor activities were evaluated. Most of them showed an excellent potency against the four tested cancer cell lines as compared with sorafenib. Particularly, a promising compound 20 was identified, which showed the most potent antitumor activities with IC50 values of 0.08, 0.09, 0.16 and 0.19 μmol/L against H460, HT-29, MKN-45 and MDA-MB-231 cell lines, respectively. The structure-activity relationship(SAR) analysis indicated that compounds with dimethylamino or diethylamino group at the C4 position of 6,7-dimethoxyquinazoline moiety exhibited superior activities than compounds bearing morpholino groups.

Key words: 6,7-Dimethoxyquinazoline derivative, Diaryl urea scaffold, Cytotoxic activity
