Abstract
In this work, gallium(III) complex with cloxyquin (5-chloro-8-quinolinol, HClQ) ligands is shown to effectively inhibit proliferation of rhabdomyosarcoma cells, the frequent, aggressive, and poorly treatable cancer of children. It offers striking selectivity to cancer cells compared to noncancerous human fibroblasts. The data reveal that the complex induces ferroptosis in rhabdomyosarcoma cells, likely due to interfering with iron metabolism. Importantly, it can kill both bulk and stem rhabdomyosarcoma cells. To the best of our knowledge, this is the first compound based on metal other than Fe capable of inducing ferroptosis in cancer cells.
期刊介绍:
Bioinorganic Chemistry and Applications is primarily devoted to original research papers, but also publishes review articles, editorials, and letter to the editor in the general field of bioinorganic chemistry and its applications. Its scope includes all aspects of bioinorganic chemistry, including bioorganometallic chemistry and applied bioinorganic chemistry. The journal welcomes papers relating to metalloenzymes and model compounds, metal-based drugs, biomaterials, biocatalysis and bioelectronics, metals in biology and medicine, metals toxicology and metals in the environment, metal interactions with biomolecules and spectroscopic applications.
