A series of 4-anilinoquinolinylchalcone derivatives were synthesized and evaluated for antiproliferative activities against the growth of human cancer cell lines (Huh-7 and MDA-MB-231) and normal lung cells (MRC-5). The results exhibited low cytotoxicity against human lung cells (MRC-5). Among them, (E)-3-4-[4-(benzyloxy)phenyl]amino}quinolin-2-yl}-1-(4-methoxyphenyl) prop-2-en-1-one (4a) was found to have the highest cytotoxicity in breast cancer cells and low cytotoxicity in normal cells. Compound 4a causes ATP depletion and apoptosis of breast cancer MDA-MB-231 cells and triggers reactive oxygen species (ROS)-dependent caspase 3/7 activation. In conclusion, it is worth studying 4-anilinoquinolinylchalcone derivatives further as new potential anticancer agents for the treatment of human cancers.
研究人员合成了一系列 4-苯胺基喹啉查尔酮衍生物,并评估了它们对人类癌细胞株(Huh-7 和 MDA-MB-231)和正常肺细胞(MRC-5)生长的抗增殖活性。结果表明,这些化合物对人肺部细胞(MRC-5)的细胞毒性较低。其中,(E)-3-4-[4-(苄氧基)苯基]氨基}喹啉-2-基}-1-(4-甲氧基苯基)丙-2-烯-1-酮(4a)对乳腺癌细胞的细胞毒性最高,而对正常细胞的细胞毒性较低。化合物 4a 会导致 ATP 耗竭和乳腺癌 MDA-MB-231 细胞凋亡,并引发活性氧(ROS)依赖性 caspase 3/7 激活。总之,4-苯胺基喹啉查尔酮衍生物作为治疗人类癌症的潜在抗癌新药值得进一步研究。
