A series of 1,4-substituted phthalazine derivatives were 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, compounds 7a–7h showed excellent selectivity for MDA-MB-231 cell line with IC50 values from 1 nmol/L to 0.92 μmol/L. A preliminary SAR study of these derivatives was performed.

Cyclic 2-diazo-1,3-dicarbonyl compounds react with diketene in the presence of rhodium(II) salts to give benzofurans as the major isolated products. The formation of intermediate products with exocyclic double bonds which isomerise to benzofurans provides support for the proposed mechanism which involves initial formation of a dioxaspirooctenone by a formal dipolar cycloaddition reaction of a carbenoid to the exocyclic double bond of diketene followed by the loss of carbon dioxide. Acyclic 2-diazo-1,3-dicarbonyl compounds give furans in poor yield.

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.
