synthesize novel bis(indolyl)-hydrazide–hydrazone derivatives (NMK-BH compounds) and recognized NMK-BH3 as the most effective one in inhibiting A549 cell proliferation and assembly of tissue-purified tubulin. Cell viability experiments showed that NMK-BH3 inhibited proliferation of human lung adenocarcinoma (A549) cells, normal human lung fibroblasts (WI38) and peripheral blood mononuclear cells (PBMC)
微管的生物学意义使其成为癌症治疗的有效靶标。在这项研究中,我们利用吲哚(一种重要的药理学支架)来合成新型的双(吲哚基)酰肼-hydr衍生物(NMK-BH化合物),并确认NMK-BH3是抑制A549细胞增殖和组装的最有效方法。组织纯化的微管蛋白。细胞活力实验表明,NMK-BH3抑制IC 50抑制人肺腺癌(A549)细胞,正常人肺成纤维细胞(WI38)和外周血单个核细胞(PBMC)的增殖值分别约为2、48.5和62μM。因此,NMK-BH3对肺癌(A549)细胞相对于正常肺成纤维细胞(WI38)和PBMC的相对较高的细胞毒性具有降低宿主毒性的治疗优势。在A549细胞系中的流式细胞仪,蛋白质印迹和免疫荧光研究表明,NMK-BH3通过解聚细胞间期和纺锤体微管而诱导G2 / M阻滞,线粒体去极化和凋亡。与这些观察结果一致,在无细胞系统中的研究表明,NMK-BH3通过IC 50抑制了微管组装。值约为7
