Fenton metal nanomedicines for imaging-guided combinatorial chemodynamic therapy against cancer.

Asian J Pharm Sci 2022 Mar 31;17(2):177-192. Epub 2021 Oct 31.

Xiangya School of Pharmaceutical Sciences, Central South University, Changsha 410013, China.

Chemodynamic therapy (CDT) is considered as a promising modality for selective cancer therapy, which is realized via Fenton reaction-mediated decomposition of endogenous HO to produce toxic hydroxyl radical (•OH) for tumor ablation. While extensive efforts have been made to develop CDT-based therapeutics, their efficacy is usually unsatisfactory due to poor catalytic activity limited by tumor microenvironment, such as anti-oxidative systems, insufficient HO, and mild acidity. To mitigate these issues, we have witnessed a surge in the development of CDT-based combinatorial nanomedicines with complementary or synergistic mechanisms for enhanced tumor therapy. Read More
