Cuproptosis is a newly discovered copper-dependent form of cell death. Intracellular glutathione (GSH) acts as a copper chelator to inhibit cuproptosis, so the reduction of GSH concentration is conducive to enhancing the cuproptosis of cells. In order to reduce GSH content and interfere with mitochondrial metabolism, a strategy based on calcium overload and GSH depletion to enhance cuproptosis is proposed in this study. Containing manganese (Mn) and copper (Cu) elements, CaCO
