activity against the A549 cancer cell line with IC50 value of 5.4 μM. All compounds had low or no effect against L02 and HUVEC non-cancer cell lines. Compound 36 was further confirmed to mainly locate mitochondria in A549 cancer cells via laser-scanning confocal microscopy. Moreover, compound 36 was proved to increase ROS production and induce cell cycle arrest in S phase. Western blot analysis illustrated
59个新颖的3-氨基-1'-(((1-芳基-1H-1,2,3-三唑-5-基)甲基)-2'-氧螺环[苯并[a]吡喃]的组合化学文库[本研究构建了设计为吩嗪,吡喃,吲哚和1,2,3-三唑药效团的杂合分子的2,3-c]吩嗪-1,3'-二氢吲哚] -2-腈。细胞毒性评估表明,某些化合物在体外对HCT116,MCF7,HepG2和A549癌细胞表现出中等的细胞毒性,其中化合物36被发现对A549癌细胞具有最佳的抗增殖活性,IC50值为5.4μM。所有化合物对LO2和HUVEC非癌细胞系均具有低或无作用。通过激光扫描共聚焦显微镜进一步证实了化合物36主要位于A549癌细胞中的线粒体。而且,化合物36被证明可以增加ROS的产生并诱导S期细胞周期停滞。Western blot分析表明,化合物36处理后,Bax / Bcl-2比值呈剂量依赖性增加,裂解的caspase-3和裂解的caspase-9均增强。上
