尽管医学取得了巨大进步,但癌症仍然是最严重的全球健康问题之一,等待新的有效疗法。在这里,我们介绍了下一代抗疟药铁喹(FQ),作为一个有前途的候选人重新定位为癌症治疗。我们报告说,FQ有效地抑制自噬,扰乱溶酶体功能和损害前列腺肿瘤的生长在体内。我们证明,FQ负调节Akt激酶和缺氧诱导因子-1 α(HIF-1α),在晚期实体癌中经常观察到的饥饿和缺氧条件下特别有效。FQ增强了几种化疗药物的抗癌活性,表明其作为现有抗癌治疗的辅助剂的潜在应用。与其母体化合物氯喹(CQ)一样,FQ在溶酶体内蓄积并使其脱酸。此外,FQ诱导溶酶体膜透化、线粒体去极化和半胱天冬酶非依赖性癌细胞死亡。总体而言,我们的工作确定ferroquine作为一个有前途的新的药物具有强大的抗癌活性。
Despite the tremendous progress in medicine, cancer remains one of the most serious global health problems awaiting new effective therapies. Here we present ferroquine (FQ), the next generation antimalarial drug, as a promising candidate for repositioning as cancer therapeutics. We report that FQ potently inhibits autophagy, perturbs lysosomal function and impairs prostate tumor growth in vivo. We demonstrate that FQ negatively regulates Akt kinase and hypoxia-inducible factor-1α (HIF-1α) and is particularly effective in starved and hypoxic conditions frequently observed in advanced solid cancers. FQ enhances the anticancer activity of several chemotherapeutics suggesting its potential application as an adjuvant to existing anticancer therapy. Alike its parent compound chloroquine (CQ), FQ accumulates within and deacidifies lysosomes. Further, FQ induces lysosomal membrane permeabilization, mitochondrial depolarization and caspase-independent cancer cell death. Overall, our work identifies ferroquine as a promising new drug with a potent anticancer activity.
