Abstract

A series of 2,4-disubstituted quinazoline derivatives were designed and synthesized. The biological results showed that most of quinazoline derivatives exhibited potent antiproliferative activities against a panel of three tumor cell lines and a good inhibitory effect against the adhesion and migration of human umbilical vein endothelial cells (HUVECs). Among these compounds, 11d was the most potent agent, that also exhibited the highest anti-angiogenesis activities in the chick embryo chorioallantoic membrane (CAM) assay.

The results of CAM assay. NaCl solution (0.9%) and thalidomide were used as a negative control and a positive control, respectively. Representative pictures of independent experiments performed in duplicate for the quinazoline derivatives 10d, 11a–d and 12d doses and controls. All filter discs had the same size, and any visual size differences are due to the various distances from which pictures were taken.
