α-Mangostin, a natural xanthone, was found to have anticancer effects, but these effects are not sufficient to be effective. To increase anticancer potential and selectivity, a triphenylphosphonium cation moiety (TPP) was introduced to α-mangostin to specifically target cancer cell mitochondria. Compared to the parent compound, the cytotoxicity of the synthesized compound 1b increased by one order
α-Mangostin 是一种天然氧杂蒽酮,被发现具有抗癌作用,但这些作用还不足以发挥作用。为了增加抗癌潜力和选择性,将三苯基膦阳离子部分 (TPP) 引入 α-山竹素中以特异性靶向癌细胞线粒体。与母体化合物相比,合成化合物1b的细胞毒性提高了一个数量级。机理分析表明,该抗肿瘤作用参与线粒体凋亡途径,通过促进细胞凋亡和使细胞周期停滞在 G0/G1 期,增加活性氧 (ROS) 的产生,降低线粒体膜电位 (Δψm) . 更值得注意的是,斑马鱼模型进一步证实了化合物 1b 的抗肿瘤活性,显着抑制癌细胞增殖和迁移,以及斑马鱼血管生成。总之,我们的结果首次表明 TPP 连接的 1b 可能导致新的线粒体靶向抗肿瘤药物的开发。
