Overview

Preclinical study demonstrates potent tumor suppression in cancer models, indicating an effective strategy to overcome oxidative resistance in chemodynamic therapy.

Key Points

To enhance chemodynamic cancer therapy by designing a multifunctional cascade nanozyme that integrates catalytic reactive oxygen species amplification with lipid metabolism reprogramming.
Synthesized a mesoporous multimetallic CuPtAu nanozyme loaded with the lipid modulator oleanolic acid and coated with hyaluronic acid (CPA/OA@HA) for CD44-targeted delivery.
Evaluated glucose oxidase-, catalase-, and peroxidase-mimicking activities alongside glutathione depletion and polyunsaturated fatty acid enrichment in vitro and in vivo.
CPA/OA@HA selectively enriched in tumors and released oleanolic acid, significantly increasing polyunsaturated fatty acid levels to provide abundant substrates for lipid peroxidation.
The nanozyme sustained hydroxyl radical generation and depleted glutathione via multi-enzyme-mimicking cascade reactions, achieving remarkable tumor suppression at low doses with high biocompatibility.
