Piperlongumine (PL), a potent anticancer agent from the plant long pepper (Piper longum), contains the 5,6-dihydropyridin-2(1H)-one heterocyclic scaffold and cinnamoyl unit. In this paper, we synthesized a series of PL analogs and evaluated their cytotoxicity against cancer cells for the sake of exploring which pharmacophore plays a more potent role in enhancing the anticancer activities of PL. These results
Piperlongumine ( PL ) 是一种来自植物长辣椒 ( Piper longum )的强效抗癌剂,含有 5,6-dihydropyridin-2(1 H )-one 杂环支架和肉桂酰基单元。在本文中,我们合成了一系列PL类似物并评估了它们对癌细胞的细胞毒性,以探索哪种药效团在增强PL的抗癌活性方面发挥更有效的作用。这些结果说明取代基的位置效应而非电子效应在PL及其类似物的细胞毒性中起一定作用。更重要的是,5,6-dihydropyridin-2(1 H)-一个单元,一种增强PL抗增殖活性的有效药效团,可与半胱胺反应并导致 ROS 产生,进而引起 ROS 诱导的下游事件的发生,进而导致细胞周期停滞和细胞凋亡。这项工作表明,引入含有迈克尔受体的内酰胺单元可能是增强药物抗癌活性的有效策略。
