study, a series of novel quaternary ammonium salts of emodin, anthraquinone and anthrone were synthesized and their anticancer activities were tested in vitro. The effects of emodin quaternary ammonium salts on cell viability, apoptosis, intracellular ROS, and mitochondrial membrane potential were investigated in A375, BGC-823, HepG2 and HELF cells. The results demonstrated that compound 4a induced morphological
大黄素(Emodin)是一种从
大黄(Rheum palmatum L.)分离的天然
蒽醌衍
生物,具有良好的抗癌作用。在这项研究中,合成了
大黄素,
蒽醌和
蒽酮的一系列新型季
铵盐,并在体外测试了它们的抗癌活性。在A375,BGC-823,HepG2和HELF细胞中研究了
大黄素季
铵盐对细胞活力,细胞凋亡,细胞内ROS和线粒体膜电位的影响。结果表明化合物4a诱导了形态变化并降低了细胞活力。使用DAPI染色和Annexin V-FITC /
PI染色观察化合物4a触发的凋亡。化合物4aP53和Caspase-3的上调显示,A375诱导的A375细胞凋亡与线粒体膜电位(ΔΨm)的耗散有关。用
大黄素衍
生物处理癌细胞后,它们产生活性氧(ROS)的能力显着提高,线粒体膜电位降低。另外,共聚焦显微镜测定法证实化合物4a主要位于A375细胞的线粒体中。这些结果表明化合物4a具有用于癌症治疗的潜力。
