配位饱和且取代惰性的环金属化铱（Ⅲ）配合物由于优秀的磷光特性，在生物成像和生物传感等方面有着广泛的应用。近年来，该类铱配合物由于有效的抗肿瘤效力和新颖的抗肿瘤机制，在抗肿瘤方面的应用也引起了广泛关注。本文主要对磷光环金属化铱（Ⅲ）配合物（结构通式为[Ir（C^N）2（N^N）]+）在抗癌化疗和光动力治疗两方面的最新研究进展进行了综述；分类总结了靶向不同细胞器，作为蛋白-蛋白相互作用抑制剂，以及应用于单光子和双光子光动力治疗的环金属化铱（Ⅲ）配合物，为开发新型金属抗肿瘤药物提供参考。最后，对环金属化铱（Ⅲ）配合物在抗癌应用方面的前景进行了展望。
Due to the excellent phosphorescent properties, the coordinatively saturated and substitutionally inert cyclometalated iridium(Ⅲ) complexes have been widely used in biological imaging and biosensing. In recent years, the application of this kind of iridium(Ⅲ) complexes in cancer treatment has attracted wide attention due to its anticancer efficacy and novel mechanisms. Recent advances of phosphorescent cyclometalated iridium(Ⅲ) complexes of the formula [Ir(C^N)2(N^N)]+ in anticancer chemotherapy and photodynamic therapy (PDT) are reviewed in this article. The iridium(Ⅲ) complexes targeting different organelles or as protein-protein interactions inhibitors or being applied in one-photon and two-photon PDT are summarized and discussed, which provides guidance for the development of new metal-based anticancer drugs. Finally, the development and application of phosphorescent cyclometalated iridium(Ⅲ) complexes in cancer treatment is discussed and prospected.
