A new series of imidazo[2, 1-b]thiazole-based chalcone derivatives were designed, synthesized, and tested for their anticancer activities. Firstly, the cytotoxic ability of the compounds was tested on three different types of cancer cells, namely colorectal adenocarcinoma (HT-29), lung carcinoma (A-549), breast adenocarcinoma (MCF-7), and mouse fibroblast cells (3T3-L1) by XTT tests. Afterwards, further
设计、合成了一系列新的基于咪唑并[2, 1-b]噻唑的查尔酮衍生物,并测试了它们的抗癌活性。首先,在三种不同类型的癌细胞上测试了化合物的细胞毒能力,即结肠直肠癌 (HT-29)、肺癌 (A-549)、乳腺癌 (MCF-7) 和小鼠成纤维细胞 (3T3- L1) 通过 XTT 测试。之后,用具有最低IC 50和最高SI值的化合物3j对MCF-7细胞进行了进一步的抗癌活性研究。XTT 结果显示,所有测试化合物对癌细胞的细胞毒活性都比正常的 3T3-L1 细胞高得多。在这些化合物中,3j的 IC 50尤为突出MCF-7 细胞上的 (9.76 µM) 和 SI (14.99) 值。流式细胞术分析证明,3j处理的 MCF-7 细胞导致线粒体膜去极化、多半胱天冬酶活化,并最终导致细胞凋亡。此外,进行了计算机分子对接方法以确认实验观察并研究化合物3j的功效。通过分子对接研究研究了3j对 DNA 十二聚体和
