cells (MCF 10A). Some of the active compounds were evaluated for clonogenic cell survival and apoptotic effects in cancer cells (DAPI nuclear staining, Comet assay, Annexin-V-FITC/PI dual staining, flow cytometry, and western blot analysis with relevant proteins). All compounds were tested for hTopoIIα inhibitory activity. The investigated series compounds showed important properties like significant
两个系列的(杂)芳基氨基萘醌和苯并稠合咔唑醌被考虑用于研究,理由是相关的结构基序存在于许多药物、临床试验药物、天然产物和 hTopoIIα 抑制剂中。通过脱氢C N 和Pd催化C反应共合成42种化合物C 键形成转换。这些化合物针对多种癌细胞进行了筛选,包括高度转移的癌细胞(MCF-7、MDA-MB-231、H-357 和 HEK293T)和正常细胞(MCF 10A)。评估了一些活性化合物在癌细胞中的克隆形成细胞存活和细胞凋亡效应(DAPI 核染色、彗星试验、膜联蛋白-V-FITC/PI 双染色、流式细胞术和相关蛋白质的蛋白质印迹分析)。测试所有化合物的 hTopoIIα 抑制活性。研究的系列化合物显示出重要的特性,例如在 S 期细胞周期停滞的癌细胞中显着的细胞凋亡抗增殖和下调 NF-κβ 信号级联,对正常细胞的细胞毒性相对较小,与抗癌药物依托泊苷相比,抑制 hTopoIIα 的效率更高.
