Sorafenib-mediated chemotherapy is currently the first choice for hepatocellular carcinoma (HCC) that cannot be surgically excised, and can significantly improve the survival of patients. However, its poor water solubility restricts its bioavailability, and long-term single use of it does not achieve satisfactory HCC therapy effects. Herein, we report a novel cascaded copper-based metal-organic framework (MOF) therapeutic nanocatalyst using HKUST-1 by integrating cyclooxygenase-2 (COX-2) inhibitor meloxicam (Mel) and chemotherapeutic agent sorafenib (Sol) to amplify HCC therapy. This HKUST-1 nanocatalyst can be degraded by glutathione (GSH) into a Fenton-like agent to trigger chemodynamic therapy (CDT). CDT-mediated cytotoxic reactive oxygen species (ROS) can activate ferroptosis by accumulating lipid peroxides (LPO). Alternatively, GSH depletion not only deactivates glutathione peroxidase 4 (GPX4) to trigger ferroptosis, but also leads to oxidative stress amplification. Moreover, Sol can also activate ferroptosis by inhibiting system XC-, resulting in cascade-amplified ferroptosis mediated HCC therapy. Furthermore, the down-regulation of COX-2 can induce PINK1/Parkin-mediated mitophagy to further act synergistically with Sol-mediated chemotherapy. Therefore, this HKUST-1 nanocatalyst provides a novel strategy to regulate GSH and COX-2 levels for amplified chemo/chemodynamic and ferroptosis-mediated HCC therapy.Copyright © 2021 Elsevier Inc.
