(Z)-2-(benzo[d][1,3]dioxol-5-yl) and (Z)-2,3-dihydrobenzo[b][1,4]dioxin-6-yl analogs of 2- and 3-phenylacetonitriles has been synthesized and evaluated for their anti-cancer activities against a panel of 60 human cancer cell lines. The dihydrodioxin analog 3j and dioxol analogs 5e and 7e exhibited the most potent anti-cancer activity of all the analogs synthesized in this study, with GI50 values of <100 nM against
( Z )-2-(苯并[ d ][1,3]二氧杂环己烷-5-基) 和 ( Z )-2,3-二氢苯并[ b ][1,4]二恶英-6-基类似物的小型文库已合成 2- 和 3-苯基乙腈,并评估其针对 60 种人类癌细胞系的抗癌活性。二氢二恶英类似物3j和二氧杂环戊醇类似物5e和7e在本研究中合成的所有类似物中表现出最有效的抗癌活性,其GI 50值<100 id=81>3j在体外对微管蛋白聚合有任何程度的抑制。通过微管蛋白二聚体的虚拟对接研究确定了3j和结构相关的微管蛋白抑制剂DMU-212的结合模式。化合物3j停靠在微管蛋白二聚体界面的秋水仙碱结合位点。观察到3j的 Full-Fitness (FF) 评分显着高于DMU-212 ,这与观察到的抗癌效力(GI 50值)非常吻合。二氧杂环戊醇类似物5e和7e发挥细胞毒性作用的机制目前尚不清楚,但它们不太可能影响微管蛋白动力学。然而,这些发现表明,苯
