Abstract: A series of highly active CF3-containing 3'-(nitroisoxazole)spiro[pyrrolidin-3,2'-oxindoles] were synthesized and found to be novel glutathione peroxidase 4 (GPX4)/mouse double minute 2 (MDM2) dual inhibitors. Bioactive spirooxindole and isoxazole skeletons were combined, and the resulting compounds exhibited strong activities against both targets. In particular, compound 3d displayed excellent activity in the suppression of MDM2-mediated degradation of p53, as well as levels of GPX4, in MCF-7 breast cancer cells. Moreover, 3d also exhibited inhibitory effects on MDM2 and GPX4 in MCF-7 xenograft model to trigger ferroptotic and apoptotic cell death in in vivo experiments, which was consistent with the results of in vitro experiments.
