Herein we present half-sandwich Ir complexes [(η-Cp)Ir(OˆC)Cl] containing OˆC(NHC)-chelating ligand as anticancer and antimetastasis agents. All the complexes displayed high potency in vitro against a wide range of cancer cells. In addition, Ir2 significantly curb tumor growth in a colon cancer mouse xenograft model in vivo. Further mechanism of action studies indicate that Ir2-initiated apoptosis occurs through ROS-mediated cross-talk between mitochondria and lysosomes.
在此，我们提出了含有 OˆC(NHC)-螯合配体的半三明治 Ir 配合物 [(η-Cp)Ir(OˆC)Cl]，作为抗癌和抗转移药物。所有配合物在体外对广泛的癌细胞均显示出高活性。此外，Ir2 在体内结肠癌小鼠异种移植模型中显著抑制肿瘤生长。进一步的作用机制研究表明，Ir2 诱导的细胞凋亡是通过 ROS 介导的线粒体和溶酶体之间的串扰发生的。
