cytotoxicity against resistant Bel-7402/5-FU cells with an IC50 value of 0.065 ± 0.016 μM and a lower resistant factor value of 0.32. In addition, all conjugate molecules efficiently triggered cell cycle arrest at S + G2 phase, induced apoptosis, disrupted the microtubule network and showed antimigratory activity in Bel-7402/5-FU cells. Finally, three conjugates regulated the levels of cell cycle arrest-
当前,对化疗药物的多药耐药性(MDR)是肝细胞癌治疗的主要障碍。具有抗MDR活性的新型抗肿瘤药的开发是克服癌症耐药性的有效途径。在本研究中,合成了新的鬼臼毒素-NSAIDs缀合物,并在体外评估了它们的抗增殖活性。最有效的缀合物A1对耐药的Bel-7402 / 5-FU细胞表现出选择性的细胞毒性,IC50值为0.065±0.016μM,较低的耐药因子值为0.32。此外,所有结合物分子均能有效触发细胞周期停滞在S + G2期,诱导细胞凋亡,破坏微管网络,并在Bel-7402 / 5-FU细胞中显示出抗迁移活性。最后,三种结合物调节细胞周期阻滞,凋亡,迁移,炎症和MDR相关蛋白,以及Bel-7402 / 5-FU细胞中的三种信号传导,是通过一些但不是全部相似的分子机制实现的。总之,这些发现首次突显了鬼臼毒素-NSAIDs缀合物的细胞毒性和多功能抗MDR特性,这可能是抗药性肝细胞癌干预的有希望的候选者。
