A series of 1-benzylidene-3,4-dihydronaphthalen-2-one derivatives were designed and synthesized, and their biological activities in vitro and in vivo were evaluated. The results showed a number of the title compounds exhibiting potent nanomolar activity in several human cancer cell lines. Of these, compound 22b showed the strongest inhibitory activity against human CEM, MDA-MBA-435, and K562 cells
设计并合成了一系列的1-亚苄基-3,4-二氢萘-2-酮衍生物,并对其在体外和体内的生物学活性进行了评价。结果表明,许多标题化合物在几种人类癌细胞系中均显示出强大的纳摩尔活性。其中,化合物22b对人CEM,MDA-MBA-435和K562细胞表现出最强的抑制活性(IC 50 = 1 nM),在体外抑制微管蛋白聚合(IC 50 = 3.93μM),并显着诱导细胞在G2 / M阶段停止循环。此外,化合物22b可以明显抑制结肠裸鼠异种移植肿瘤模型中的肿瘤生长,并且在达到类似的肿瘤抑制作用时似乎比CA-4更安全。这项研究为靶向微管蛋白的抗肿瘤药物的进一步开发提供了新的分子支架。
