In an attempt to develop potent and selective antitumor agents, a series of novel 1,4-disubstituted phthalazine derivatives was designed and synthesized. All the prepared compounds were screened for their cytotoxic activities against A549, HT-29 and MDA-MB-231 cell lines in vitro. Among them, seven compounds (7a-7e, 7j and 7i) displayed excellent selectivity for MDA-MB-231 cells with IC(50) values in the nM range, a desirable range for pharmacological testing. The most promising compound, 7a (IC(50) = 3.79 mu M, 2.32 mu M, 0.84 nM), was 5.6-, 10.8- and 6.9 x 10(4)- times more active than PTK-787 (IC(50) = 21.16 mu M, 22.11 mu M, 57.72 mu M), respectively.
