  Styryl-N-phenyl-N′-(2-chloroethyl)ureas and styrylphenylimidazolidin-2-ones as new potent microtubule-disrupting agents using combretastatin A-4 as model

  摘要：

  Combretastatin A-4 (CA-4) is a well-studied and attractive molecular template to develop new antimitotics. Several thousand of modifications were performed on the ring B and the ethenyl bridge of CA-4 but only a few involved the trimethoxyphenyl moiety (TMP, ring A) often considered essential to the antiproliferative and antimicrotubule activities. In this study, we described the design, the preparation, the characterization and the biological evaluation of three new series of CA-4 analogs namely styryl-N-phenyl-N'-ethylureas (SEUs), styryl-N-phenyl-N'-(2-chloroethyl)ureas (SCEUs) and styrylphenylimidazolidin-2-ones (SIMZs) bearing a 3-Cl (series a), 3,5-Me (series b) and TMP (series c) substituents, respectively. All SCEU and SIMZ Z-isomers were active in the high and the low nanomolar range, respectively. Conversely to SEUs and their E-isomers that were significantly less active or inactive. Interestingly, the IMP moiety is giving rise to derivatives exhibiting the lowest antiproliferative activity in the SCEU series (10c) and the most active compound in the SIMZ series (12c). Moreover, SIMZ Z-isomers bearing either a 3-Cl (12a) or a 3,5-Me (12b) exhibited antiproliferative activities that are also in the same order of magnitude as 12c. All SCEU and SIMZ Z-isomers also arrested the cell cycle progression in G2/M phase, bound to the colchicine-binding site and disrupted the cytoskeleton of cancer cells. In addition to the promising and innovative microtubule-disrupting properties of SCEUs and SIMZs, these results show that the IMP moiety is not essential for the cytocidal activity of these new CA-4 analogs.
