1a resembles that of the cis alkene 1. Additional inactive compounds prepared include the benzylisoquinoline series 28-32 as well as the protoberberines 38 and 39. Shortening the two-carbon bridge of 1a to a one-carbon bridge in the diphenylmethane 20 resulted in a decrease in cytotoxicity and tubulin polymerization inhibitory activity. Although the corresponding benzophenone 18 was as active as 1a as
已经制备了一系列对苯二酚,并在五种人类癌细胞系A-549非小细胞肺癌,MCF-7乳腺癌,HT-29结肠癌,SKMEL-5黑色素瘤和MLM黑色素瘤中测试了细胞毒性。顺式斯蒂芬斯6a-f在所有五个细胞系中均被证明具有细胞毒性,其效力可与康美他汀A-4媲美。这些细胞毒性化合物都是微管蛋白聚合的有效抑制剂。相应的反丁苯橡胶7b-f作为微管蛋白聚合抑制剂没有活性,并且在5种癌细胞系中的细胞毒性明显较小。在二氢系列中,8b,8c和8f作为微管蛋白聚合抑制剂没有活性,而8a,8d和8e的活性低于相应的顺式化合物6a,6d和6e。菲23b缺乏对微管蛋白聚合的抑制活性和细胞毒性,作为前导化合物1的构象刚性类似物合成的Silbenes的活性表明,斯蒂芬酯的活性不是由于完全平面的构象。同样,构象受限的类似物26的无活性表明1a的生物活性构象与顺式烯烃1相似。制备的其他无活性化合物包括苄基异喹啉系列28-32以及
