The synthesized hybrid compounds were screened for their anticancer activity against various human cancer and normal cell lines. N-{2-[(4-Bromo- and N-{2-[(3-bromo-phenyl)methyl]-4-oxoquinazolin-3(4H)-yl}-2-oxo-2H-1-benzopyran-3-carboxamides exhibited the highest cytotoxic effect on the PC-3 prostate cancer cell line: IC50 35.3 +/- 0.6 and 36.8 +/- 0.8 mu g/L, respectively. N-{2-[(4-Fluoro-, N-{2-[(4-bromo-, and N-{2-[(3,4-dichloro-phenyl)methyl]-4-oxoquinazolin-3(4H)-yl}-2-oxo-2H-1-benzopyran-3-carboxamides showed the highest activity against the MCF-7 breast cancer cell line: IC50 48.5 +/- 0.4, 44.8 +/- 0.4 and 46.1 +/- 0.5 mu g/L, respectively.EnglishArticle1608-3393
