clinically effective chemotherapies for cancer treatment but might be limited by the acquired or intrinsic resistance of cancer cells to apoptosis. The vulnerability of therapy-resistant cancers to ferroptosis provides an alternative way to overcome drug resistance. In this study, on the basis of the MTAs obtained in our previous studies, a series of MTAs were synthesized, and detailed structure–activity
微管靶向剂 (MTA) 被用作临床上有效的癌症治疗化学疗法,但可能受到癌细胞对细胞凋亡的获得性或内在抗性的限制。耐药性癌症对铁死亡的脆弱性提供了一种克服耐药性的替代方法。本研究在前期研究获得的MTA的基础上,合成了一系列MTA,并通过广泛的分子动力学研究获得了详细的构效关系。其中,二苯基乙烯衍生物化合物33在体外和体内显示出最有效的活性,IC 50对六种癌细胞系的 10-50 nM 值和 78.6% 的体内肿瘤生长抑制。有趣的是,尽管化合物33充当 MTA,但主要通过细胞铁死亡而非细胞凋亡引发细胞死亡,这可能为根除与细胞凋亡相关的耐药性提供了一种替代方法。
