analogues against MDA-MB-231 cells. The antibacterial assay showed that K. rhizophila was the most susceptible bacteria to the compounds, followed by S. aureus. Compound 4 and the SMDTC-derived analogues 3, 5, Cu7 and Cu9 possessed the highest antibacterial activity. These active analogues were further assessed, whereby 3 possessed the highest antibacterial activity with an MIC of <24.4 µg/mL against
通过不同链长的二羰基与二硫代氨基甲酸甲酯(SMDTC)和二硫代氨基甲酸S-苄酯(SBDTC)反应,然后与Cu(II)离子配位,合成了一系列新型大环希夫碱配体及其Cu(II)配合物。获得了化合物 4(一种 SBDTC-二乙酰类似物)和 Cu7(一种 SMDTC-己二酮 Cu (II) 络合物)的 X 射线晶体结构。这些化合物的抗癌评估表明,Cu1(一种 SMDTC-乙二醛复合物)对 MCF-7 和 MDA-MB-231 乳腺癌细胞表现出最高的细胞毒活性,IC50 值分别为 1.7 µM 和 1.4 µM。链长度和细胞毒活性的影响之间没有观察到明显的模式;然而,SMDTC 衍生的类似物比 SBDTC 衍生的类似物对 MDA-MB-231 细胞的活性更强。抗菌测定表明,根瘤菌是对这些化合物最敏感的细菌,其次是金黄色葡萄球菌。化合物4和SMDTC衍生的类似物3、5、Cu7和Cu9具有最高的抗菌活性
