Sažetak
A series of new N, N-dimethylaminopropyl- and 2-imidazolinyl-substituted derivatives of benzo[b]thienyl- and thieno[2, 3-b]thienyl-carboxanilides and benzo[b]thieno[2, 3-c]- and thieno[3’, 2’:4, 5]thieno[2, 3-c]quinolones were prepared. Quinolones were prepared by the reaction of photochemical dehydrohalogenation of corresponding anilides. Carboxanilides and quinolones were tested for the antiproliferative activity. 2-Imidazolinyl-substituted derivatives showed very prominent activity. Using the experimentally obtained antitumor measurements, 3D-derived QSAR analysis was performed for the set of compounds. Higly predicitive 3D-derived QSAR models were obtained and molecular properties that have the highest impact on antitumor activity were identified. Carboxanilides 6a-c and quinolones 9a-c and 11a were evaluated for DNA binding propensities and topoisomerases I and II inhibition as part of their mechanism of action assessment. The evaluated differences in the mode of action nicely correlate with the results of the 3D- QSAR analysis. Taken together the results indicate which modifications of the compounds from the series should further improve their anticancer properties.
