  摘要：

  合成了一系列与康布雷他汀A-4（1a）相关的顺式和反式对苯二甲酰胺，并使用六种人类癌细胞系对其进行了评估，并评估了其在芳基B环的3'-位置处的多种取代基（NCI-H460肺癌，BXPC-3胰腺，SK-N-SH神经母细胞瘤，SW1736甲状腺，DU-145前列腺癌和FADU咽鳞状肉瘤）以及P-388鼠淋巴细胞白血病细胞系。几种顺式-二苯乙烯衍生物对所有使用的细胞系均具有明显的抑制作用，其效力可与亲本1a媲美。所有都是微管蛋白聚合的有效抑制剂。相应的反丁苯二酚作为微管蛋白聚合抑制剂几乎没有或没有活性，并且对七个癌细胞系相对无活性。就抑制癌细胞生长和微管蛋白聚合而言，二甲基氨基和溴顺式-苯乙烯衍生物是最有效的新衍生物，后者的生物活性接近1a。作为本研究的一部分，康柏他汀A-4（1b）的3'-O-磷酸盐的X射线晶体结构已得到成功阐明。化合物1b被称为“ combretastatin A-4前药”，目前正在治疗人类癌症患者的临床试验中。
