conjugates was synthesized and evaluated for their antiproliferative activity against a panel of selected human cancer cell lines including A549 (lung cancer), HCT116 (colon cancer), MCF7 (breast cancer), and SK-MEL-28 (melanoma). Among the synthesized molecules (14a-m and 15a-d), compound 14d displayed remarkable activity against A549, HCT116 and SK-MEL-28 cells with IC50 values < 4 μM with the best
合成了一系列 17 种吲哚/吡咯并氮杂酮-羟吲哚偶联物,并评估了它们对一组选定的人类癌细胞系的抗增殖活性,包括 A549(肺癌)、HCT116(结肠癌)、MCF7(乳腺癌)和 SK-MEL -28(黑色素瘤)。在合成的分子(14a - m和15a - d)中,化合物14d对 A549、HCT116 和 SK-MEL-28 细胞表现出显着的活性,IC 50值 < 4 μM,具有最佳的细胞毒性和对肺癌的 13 倍选择性细胞(IC 50值为 2.33 μM)高于正常大鼠肾细胞(NRK)。此外,14d介导的细胞凋亡以剂量依赖性方式影响癌细胞的细胞和核形态。伤口愈合和克隆形成测定推断细胞生长和迁移的抑制。化合物14d的靶向研究证实了其 DNA 嵌入能力和 Topo I 抑制活性,这已通过分子建模研究得到加强。最后,通过进行计算机ADME/T 预测研究来确定有效化合物的药物相似性。
