Two series of novel 2-(2-arylmethylene)hydrazinyl-4-aminoquinazoline derivatives were synthesized and evaluated for their cytotoxicity against H-460, HT-29, HepG2 and SGC-7901 cancer cell lines in vitro. Most compounds displayed moderate to excellent activity, with IC(50) values ranging from 0.015 to 4.09 μM against all tested cell lines, respectively. The most promising compound 9p (E)-2-(2-((1-(2,3-dichlorobenzyl)-1H-imidazol-2-yl)methylene)hydrazinyl)-N-(1-methylpiperidin-4-yl)quinazolin-4-amine with IC(50) values of 0.031 μM, 0.015 μM, 0.53 μM and 0.58 μM, which was 4- to 224 times more active than references 10 and Iressa, had emerged as a lead for further structural modifications.
