Three benzoxanthone derivatives were synthesized through a new photochemical strategy. The in vitro cytotoxic activity of these compounds was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, and their partition coefficients (logP) were measured by shake flask method. The pKa values of the compounds were detected by potentionmetric titration. The interaction of
通过新的光化学策略合成了三种苯并蒽酮衍生物。用3-(4,5-二甲基噻唑-2-基)-2,5-二苯基溴化四唑(MTT)法评价这些化合物的体外细胞毒活性,用摇瓶法测定它们的分配系数(log P ) . 通过电位滴定法检测化合物的p K a值。通过电子吸收、发光光谱和粘度研究了化合物与小牛胸腺DNA (CT-DNA) 的相互作用。进行了分子对接分析。通过细胞凋亡、细胞周期阻滞、细胞内 Ca 2+评价化合物的抗肿瘤功效浓度和活性氧 (ROS) 水平。使用 JC-1(5,5',6,6'-四氯-1,1,3',3'-四乙基-咪达羰花青碘化物)作为荧光探针测定线粒体膜电位。Western blot检测Bcl-2家族蛋白、caspase 3和聚ADP-核糖聚合酶(PARP)的表达。结果表明,这些化合物通过 ROS 介导的线粒体功能障碍途径诱导细胞凋亡。这项工作为合成苯并氧杂蒽酮衍生物提供了一种有效的方法,有助于理解细胞凋亡机制。
