Design, synthesis, and biological evaluation of quinazoline derivatives containing piperazine moieties as antitumor agents

A series of novel quinazoline derivatives containing piperazine analogs are synthesized via substitution reactions with 6,7-disubstituted 4-chloroquinazoline and benzyl piperazine (amido piperazine). Potent antiproliferative activities are observed against A549, HepG2, K562, and PC-3 withN-(3-chlorophenyl)-2-(4-(7-methoxy-6-(3-morpholino-propoxy)quinazoline-4-yl)piperazine-1-yl)acetamidenameC9showing excellent activity. This active derivative was screened for cell migration ability, proliferation effects, and apoptosis against A549 and PC-3 cells, with the result showing biological activity almost equal to that of the control gefitinib.
