Identification of a novel toxicophore in anti-cancer chemotherapeutics that targets mitochondrial respiratory complex I
摘要:
线粒体功能的破坏会选择性地针对依赖氧化磷酸化的肿瘤细胞。然而,由于心脏细胞对能量的需求很高,它们不成比例地成为线粒体毒素的目标,导致心脏功能丧失。对姆布利替尼对心脏细胞影响的分析表明,这种药物并不像报道的那样抑制HER2,而是直接抑制线粒体呼吸复合体I,降低心脏细胞的搏动率,长期接触会导致细胞死亡。我们使用了一个 mubritinib 化学变体库,结果表明对 1H-1,2,3-三唑进行修饰可改变复合体 I 的抑制作用,并确定杂环 1,3- 氮基团为毒性分子。在第二种抗癌疗法羧基氨基三唑(CAI)中也存在相同的毒性团,我们证明 CAI 也是通过毒性团介导的复合物 I 抑制作用发挥作用的。复合体 I 抑制作用与抗癌细胞活性直接相关,而毒性团的修饰会削弱这些化合物对癌细胞增殖和凋亡的预期作用。
