particularly for ALL-5 and LoVo cell lines. Cell cycle analysis of the most potent molecules on ALL-5 and MCF-7 cell lines revealed contrasting effects, where M-phase arrest was observed in MCF-7 cells but not in ALL-5 cells. Molecular docking studies of all derivatives to the colchicine-binding site were performed and it was found that five of the derivatives showed strong β-tubulin binding energies, lower
秋水仙碱是一种植物生物碱,具有广泛的生物学和药理特性。它已发现可用作抗炎剂,并通过阻止微管蛋白二聚体聚合导致有丝分裂死亡来破坏微管的能力,从而显示出抗癌作用。然而,迄今为止,不良副作用限制了其在癌症治疗中的应用。这导致重新努力鉴定毒性较小的衍生物。在本文中,我们描述了一组新型双和三修饰秋水仙碱衍生物的合成。这些衍生物针对原发性急性淋巴细胞白血病 (ALL-5) 细胞和几种已建立的癌细胞系进行了测试,包括 A549、MCF-7、LoVo 和 LoVo/DX。新型衍生物在低纳摩尔范围内具有活性,7-deacetyl-10-thiocolchicine 类似物对 ALL-5 细胞更有效,而 4-iodo-7-deacetyl-10-thiocolchicine 类似物对 LoVo 细胞系更有效。此外,大多数合成的化合物显示出良好的选择性指数 (SI),特别是对于 ALL-5 和 LoVo 细胞系。对
