In the search for novel anticancer agents, we designed and synthesized a series of quinoline-based oxadiazole derivatives and assayed their in vitro cytotoxic efficacy against human breast cancer MCF-7 cell line. The most promising compounds in the present series (Q8, S3, S6) showed excellent activity and inhibited growth of breast cancer cell MCF-7 with 50% inhibitory concentration (IC50) of 8.31, 9.81, and 9.96 µM, respectively. The results of the present study reveal reduced IC50 values in a time- and dose-dependent mode with high specificity for MCF-7 (IC50 of 10 μM at 24 h) versus normal breast cells. Apoptosis assay using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) also suggested that this compound induced cell death by apoptosis.
在寻找新型抗癌剂的过程中,我们设计并合成了一系列喹啉基噁二唑衍生物,并检测了它们对人类乳腺癌 MCF-7 细胞系的体外细胞毒性。本系列中最有前景的化合物(Q8、S3、S6)表现出了极佳的活性,抑制了乳腺癌细胞 MCF-7 的生长,50% 抑制浓度(IC50)分别为 8.31、9.81 和 9.96 µM。本研究的结果表明,与正常乳腺细胞相比,MCF-7 的 IC50 值(24 h 时的 IC50 为 10 μM)降低了,且具有时间和剂量依赖性,特异性很高。使用 3-(4,5-二甲基噻唑-2-基)-2,5-二苯基溴化四氮唑(MTT)进行的细胞凋亡检测也表明,该化合物可诱导细胞凋亡。
