Expanding our studies on the anti-angiogenesis activities of 2,4-disubstituted quinazoline derivatives [8], a series of novel N-(2-(quinazolin-2-yl)phenyl)benzamide (SZ) derivatives were designed and synthesized. Cytotoxicity assays indicated that most of these compounds displayed similar cytotoxicity against tumor cells in comparison with our previously reported, but showed a higher cytotoxicity against HUVECs. The SZ derivatives showed a remarkable inhibitive effect against the migration and adhesion of HUVECs, in addition to demonstrating significant in vivo anti-angiogenesis activities in the chick embryo chorioallantoic membrane (CAM) assay. The results proved that the introduction of an aryl group with a basic amide side chain on the 4′ position linked to the amide of the C-2 substituted quinazoline scaffold is an effective approach to improve the anti-angiogenic activity of quinazoline derivatives.
