A new series of N-(2-(1H-benzo[d]imidazol-2-yl)phenyl) cinnamides was prepared and evaluated for their in vitro cytotoxic activity using various cancer cell lines viz. A549 (human non-small cell lung cancer), MDA-MB-231 (human triple negative breast cancer), B16-F10 (mouse melanoma), BT-474 (human breast cancer), and 4T1 (mouse triple negative breast cancer). In the series of tested compounds, 12h
制备了一系列新的N-(2-(1 H-苯并[ d ]咪唑-2-基)苯基)肉桂酸酯,并使用多种癌细胞系评估了它们的体外细胞毒性活性。A549(人类非小细胞肺癌),MDA-MB-231(人类三阴性乳腺癌),B16-F10(小鼠黑色素瘤),BT-474(人类乳腺癌)和4T1(小鼠三阴性乳腺癌) 。在一系列测试的化合物中,12h对非小细胞肺癌细胞系表现出有效的细胞毒活性,IC 50值为0.29±0.02 µM。最有效的化合物12h的细胞毒性还对NRK-52E(正常大鼠肾上皮细胞系)进行了测试,与癌细胞相比,其细胞毒性更低。微管蛋白聚合测定表明化合物12h能够通过抑制微管蛋白聚合来阻止细胞分裂。此外,分子对接研究还表明在微管蛋白的秋水仙碱结合位点结合了12h。细胞周期分析表明,化合物12h阻滞了G2 / M期。此外,通过各种染色研究(如a啶橙,DAPI,线粒体膜电位分析,膜联蛋白V - FITC和DC
