ABSTRACT Atomically precise gold nanoclusters (NCs), possessing characteristics of molecules and nanoparticles, offer a promising solution to the challenges faced by existing pyroptosis inducers. Their abilities catalyze generation reactive oxygen species enhance radiosensitization position them as effective agents for activating pyroptosis. However, their catalytic efficiency is often compromised limited geometrically accessible spaces around active sites lack suitable ligands. Leveraging exposed metal centers in mononuclear organometallic catalysts tunable ligand NCs, herein, ethynylferrocene (EFc) was utilized amplify peroxidase (POD)‐like activity NCs establishing unshielded center electron donor‐acceptor interaction between EFc Au core. The resulting 8 Fe 2 with excellent POD‐mimicking could efficiently trigger inducing intracellular oxidative stress. Moreover, potential deplete glutathione enable magnetic resonance imaging, also induce ferroptosis serve diagnostic tool tumors. All these processes can be further potentiated X‐ray radiation, taking advantage high atomic number gold. This work opens new avenues engineering properties broadens applications biomedicine.

Drug resistance is a common challenge in clinical tumor treatment. A reduction drug sensitivity of cells often accompanied by an increase autophagy levels, leading to autophagy-related resistance. The effectiveness combining chemotherapy drugs with inducers/inhibitors has been widely confirmed, but the mechanisms are still unclear. Ferroptosis and pyroptosis can be affected various types autophagy. Therefore, ferroptosis have crosstalk via autophagy, potentially switch cell death under certain conditions. As two forms inflammatory programmed death, different effects on inflammation, cGAS-STING signaling pathway also involved. it plays important role progression some chronic diseases.
