  3-(3-Methylisoxazol-5-yl) and 3-(pyrimidin-2-yl)-2-styrylquinazolin-4(3H)-ones 8a-l and 9a,c-e,h-l were synthesized by refluxing in acetic acid the corresponding 2-methylquinazolinones 6 and 8 with the opportune benzoic aldehyde for 12 h. The synthesized styrylquinazolinones 8a-l and 9a,c-e,h-l were tested in vitro for their antileukemic activity against L-1210 (murine leukemia), K-562 (human chronic myelogenous leukemia) and HL-60 (human leukemia) cell lines showing in some cases good activity.

  In order to study the influence of 3-substitution on the cytotoxic activity of 2-styrylquinazolinones, new 6-chloro-2-styryl-3-(heteroaryl)-4(3H)-quinazolinones were synthesized by refluxing equimolar amounts of 6-chloro-2-methyl-3-(heteroaryl)-4(3H)-quinazolinones and benzaldehyde in glacial acetic acid. At 1 mug ml(-1) concentration, almost all 2-styrylquinazolinones showed some cytotoxic activity against the L1210 and K562 leukemia cell lines. However, only 6-chloro-2-styryl-3-(pyrimidin-2yl)-4(3H)-quinazolinone inhibited the growth of these cells by over 50%. This last compound was also the only member of the series that inhibited tubulin polymerization, with air IC50 value of 5.8 versus 3.2 muM for colchicine. It was also examined for effects on the growth of human MCF7 breast carcinoma cells and Burkitt lymphoma CA46 cells, which had IC50 values of 0.34 and 1.0 muM, respectively. At 10 muM 6-chloro-2-styryl-3-(pyrimidin-2yl)-4(3H)-quinazolinone induced G2/M arrest (66%) in Burkitt cells, with a mitotic index of 20%. At 3.4 muM, it caused disruption of the cellular microtubule system of the MCF7 cells. Both these cellular effects are consistent with its mechanism of action resulting from its inhibitory effect on tubulin assembly. (C) 2004 Elsevier SAS. All rights reserved.
