The synthesis and biological evaluation of 9 dimeric compounds obtained by condensation of thiocolchicine and/or podophyllotoxin with 6 different dicarboxylic acids is described. In particular, tubulin assembly assay and immunofluorescence analysis results are reported. The biological data highlighted three compounds as being more active than the others, having a marked ability to inhibit the polymerization
描述了通过硫代秋水仙碱和/或鬼臼毒素与6种不同的二羧酸缩合获得的9种二聚化合物的合成和生物学评估。特别地,报道了微管蛋白组装测定和免疫荧光分析结果。生物学数据强调了三种化合物比其他化合物更具活性,具有显着的体外抑制微管蛋白聚合的能力,并在体内对微管网络造成重大破坏。。发现间隔物单元对生物活性具有显着影响,增强了共轭化合物设计以产生新的生物活性分子的重要性,其中间隔物可用于改善溶解度并调节众所周知的抗癌药的功效。
