sesquiterpene lactones modified at the lactone ring with a thiophenol residue have been synthesized. The resulting conjugates with thiophenol have capacity for the oxidation–elimination reaction by the action of ROS of a tumor cell with the release of initial cytotoxic lactones. It has been proposed to use the resulting sulfur-containing conjugates as ROS-activated prodrugs of sesquiterpene lactones. The antiproliferative
摘要—— 已经合成了在内酯环上用苯硫酚残基修饰的倍半萜内酯衍生物。由此产生的与苯硫酚的结合物具有通过肿瘤细胞的 ROS 的作用与初始细胞毒性内酯的释放进行氧化消除反应的能力。已提议将所得含硫缀合物用作倍半萜内酯的 ROS 活化前药。已在肿瘤和假性正常细胞系上检查了缀合物的抗增殖特性。偶联物的细胞毒性低于母体内酯;然而,在某些情况下,如阿兰内酯与青蒿素的结合物,它在所有测试的肿瘤细胞系中保持中等。
