A series of novel 4,6-diphenyl-2-(1H-pyrrol-1-yl)nicotinonitrile analogues of crolibulin and combretastatin A-4 (CA-4) were discovered using a 2-(1H-pyrrol-1-yl)pyridine ring as link-bridge to retain the cis-orientations of A-ring and B-ring. All the target compounds were synthesized and evaluated for their antiproliferative activity against five human cancer cell lines. Compounds 6a-d exhibited superior
使用2-(1H-吡咯-1-基)发现了一系列新的crolibulin和康维他汀A-4(CA-4)的4,6-二苯基-2-(1H-吡咯-1-基)烟腈类似物。吡啶环作为连接桥,可保留A环和B环的顺式。合成所有目标化合物,并评估其对五种人类癌细胞系的抗增殖活性。化合物6a-d显示出优异的效力,在纳摩尔水平上具有IC 50值。特别地,化合物6a显示出与crolibulin和CA-4相似或更高的抗肿瘤活性。此外,化合物6a对微管组装的抑制作用与CA-4相当。进行了化合物6a的分子建模研究,以阐明其在微管蛋白二聚体中秋水仙碱结合位点的结合方式,
