Abstract
Platinum-based chemotherapy is widely used to treat various cancers. However, exogenous platinum is likely to cause severe side effects and drug resistance induced by upregulated glutathione (GSH) in cancer cells poses a threat to the management of cancer progression and recurrence. Anticancer copper-organic complexes are excellent candidates to substitute platinum-based chemotherapeutics, exhibiting lower systemic toxicity and even overcoming platinum-based chemotherapy resistance. Here, we report the GSH-resistance of copper(II) bis(diethyldithiocarbamate) (CuET) and its reversal of cisplatin resistance in non-small-cell lung cancer via cuproptosis. Electrochemistry and UV-vis spectroscopy studies demonstrate that CuET possesses a lower reduction potential and the reaction inertness with GSH. Importantly, CuET overcomes the drug resistance of A549/DDP cells and the anticancer effect is hardly affected by intracellular GSH levels. To improve the solubility and bioavailability, bovine serum albumin-stabilized CuET nanoparticles (NPs) are prepared and they have a high drug loading content of 27.5% and excellent physiological stability. In vitro studies manifest that CuET NPs augment the distributions in the cytosol and cytoskeleton, inducing cell death via cuproptosis in A549/DDP cells, which is distinctly different from the apoptosis pattern induced by cisplatin. In vivo antitumor evaluation shows that the nanomedicine has superior biosafety and potent antitumor activity in a cisplatin-resistant tumor model. Our study suggests that copper-organic complex-based nanosystems could be a powerful toolbox to tackle the platinum-based drug resistance and systemic toxicity concerns.

Abstract
The pursuit of mesoporous Fe-based nanoagents addresses the field of developing alternative Fe-bearing nanoagents for synergistic cancer therapy with the expectation that the use of an essential element may avoid the issues raised by the exogenous administration of other metal element-based nanoagents. Herein, we highlight the interface-engineered mesoporous FeB (mFeB) where the core mFeB is interfacially oxidized into an FeOOH nanosheet loaded with the chemotherapeutic drug doxorubicin (DOX) and further encapsuled within the double-sulfide-bonded SiO2 outer layer, denoted as mFeB@DOX-ss-SiO2, which can realize programmed drug release for synergistic cancer theranostics. When only in a tumor microenvironment, the nanoagent can be activated to release DOX from the mFeB and FeOOH nanosheets as well as expose the easily oxidized mFeB to spontaneously transform to FeOOH nanosheets with Fenton activity to facilitate chemodynamic therapy (CDT). In addition, the high photothermal conversion efficiency of mFeB@DOX-ss-SiO2 would promote CDT. Also, owing to the inherent nature of ferromagnetism and red fluorescence of DOX, mFeB@DOX-ss-SiO2 can realize T2-weighted magnetic resonance imaging and fluorescence imaging. In vivo mouse model experiments demonstrate that mFeB@DOX-ss-SiO2 with good biocompatibility realizing CDT/photothermal therapy/chemotherapy achieved complete tumor suppression. This study opens up a new way to explore theranostic nanoagents.

A reactive oxygen species-replenishing coordination polymer nanomedicine disrupts redox homeostasis and induces concurrent apoptosis-ferroptosis for combinational cancer therapy.

Abstract
Reactive oxygen species (ROS) are important signal molecules and imbalanced ROS level could lead to cell death. Elevated ROS levels in tumor tissues offer an opportunity to design ROS-responsive drug delivery systems (DDSs) or ROS-based cancer therapy such as chemodynamic therapy. However, their anticancer efficacies are hampered by the ROS-consuming nature of these DDSs as well as the high concentration of reductive agents like glutathione (GSH). Here we developed a doxorubicin (DOX)-incorporated iron coordination polymer nanoparticle (PCFD) for efficient chemo-chemodynamic cancer therapy by using a cinnamaldehyde (CA)-based ROS-replenishing organic ligand (TCA). TCA can ROS-responsively release CA to supplement intracellular ROS and deplete GSH by a thiol-Michael addition reaction, which together with DOX-triggered ROS upregulation and Fe3+-enabled GSH depletion facilitated efficient DOX release and enhanced Fenton reaction, thereby inducing redox dyshomeostasis and cancer cell death in a concurrent apoptosis-ferroptosis way. Both in vitro and in vivo study revealed that ROS-replenishing PCFD exhibited much better anticancer effect than ROS-consuming control nanoparticle PAFD. The ingenious ROS-replenishing strategy could be expanded to construct versatile ROS-responsive DDSs and ROS-based nanomedicines with potentiated anticancer activity. STATEMENT OF SIGNIFICANCE: We develop a doxorubicin (DOX)-incorporated iron coordination polymer nanoparticle (PCFD) for efficient chemo-chemodynamic cancer therapy by using a cinnamaldehyde-based reactive oxygen species (ROS)-replenishing organic ligand. This functional ligand can ROS-responsively release cinnamaldehyde to supplement intracellular H2O2 and deplete glutathione (GSH) by a thiol-Michael addition reaction, which together with DOX-triggered ROS upregulation and Fe3+-enabled GSH depletion facilitates efficient DOX release and enhanced Fenton reaction, thereby inducing redox dyshomeostasis and cancer cell death in a concurrent apoptosis-ferroptosis way. Both in vitro and in vivo study reveal that ROS-replenishing PCFD exhibit much better anticancer effect than ROS consuming counterpart. This study provides a facile and straightforward strategy to design ROS amplifying nanoplatforms for cancer treatment.
