  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.

  conjugated chromophores containing imino and hydroxyl groups are presented. Excited state intramolecular proton transfer (ESIPT) of these chromophores under one- and two-photon irradiation was surveyed. One-photon absorption spectra show the presence of internal hydrogen bond in the organic dyes containing ortho-hydroxyl group, while the corresponding dyes carrying para-hydroxyl group do not exhibit intramolecular

  在这项工作中，提出了多种含有亚氨基和羟基的新型共轭生色团。调查了这些生色团在单光子和双光子照射下的激发态分子内质子转移（ESIPT）。单光子吸收光谱表明，在含有邻羟基的有机染料中存在内部氢键，而带有对羟基的相应染料则没有分子内的氢键作用。相反，在大多数非质子和质子溶剂中，带有邻羟基的扩展发色 团显示出良好分离的双发射带，斯托克斯位移大（约160 nm），而含有对羟基苯甲酸的分子-羟基基团仅显示具有正常Stokes位移（约50 nm）的单个谱带。还可以通过近红外（近红外）飞秒激光对带有邻羟基的分子观察到双光子吸收（TPA）引起的竞争性ESIPT发射。实验表明，带有邻羟基的分子在单光子和双光子激发下能够进行ESIPT，而含有对羟基的分子则没有这种特性。2-（（（3'，4'-二甲氧基-苯基亚乙基-苯基-4-ylimino）甲基）苯酚（C1）和2-（（3'，4'，5'-三甲氧基-苯基亚乙基-苯基-
