Published: Nov. 2, 2021

Abstract Chemodynamic therapy (CDT), a novel cancer therapeutic strategy defined as the treatment using Fenton or Fenton‐like reaction to produce •OH in tumor region, was first proposed by Bu, Shi, and co‐workers 2016. Recently, with rapid development of nanomaterials, CDT has attracted tremendous attention because its unique advantages: 1) It is tumor‐selective low side effects; 2) process does not depend on external field stimulation; 3) it can modulate hypoxic immunosuppressive microenvironment; 4) cost low. In addition Fe‐involved strategies, reaction‐mediated strategies have also been proposed, which are based many other metal elements including copper, manganese, cobalt, titanium, vanadium, palladium, silver, molybdenum, ruthenium, tungsten, cerium, zinc. Moreover, combined therapies like chemotherapy, radiotherapy, phototherapy, sonodynamic therapy, immunotherapy for achieving enhanced anticancer effects. Besides, there studies that extend application antibacterial field.

Abstract Cuproptosis is a very newly recognized regulated cell death modality that distinct from known mechanisms and shows enormous prospect in cancer treatment. However, its efficacy copper‐dependent restricted by strictly copper metabolism. Herein, novel copper/iron hybrid hollow amorphous metal organic framework (HaMOF) developed as an oxidative stress amplifier metabolic disrupter for synergistic cuproptosis/ferroptosis/apoptosis anticancer therapy. The HaMOF fabricated Cu 2+ , 3,3′‐dithiobis(propionohydrazide) Fe 3+ via unsaturated coordination‐etching integration strategy, then doxorubicin loaded followed surface decoration with hyaluronan. obtained DOX@Fe/CuTH exhibits tumor microenvironment‐triggered catalytic therapeutic property, wherein it can amplify cellular simultaneously boosting H 2 O production depleting glutathione. Moreover, cause mitochondrial dysfunction downregulate the expressions of transporter ATP7A iron FPN 1, thereby leading to disorders high retentions cytoplasm •OH generation. overloaded lipoylated protein dihydrolipoamide S‐acetyltransferase aggregation lead cuproptosis. Collectively, both augmented induce potent ferroptosis, which synergizes cuproptosis DOX‐mediated apoptosis efficiently suppress growth. This bimetallic nanoplatform provides new paradigm boost cuproptosis‐related therapies.

A Metabolic Multistage Glutathione Depletion Used for Tumor-Specific Chemodynamic Therapy

ACS Nano, Journal Year: 2022, Volume and Issue: 16(3), P. 4228 - 4238

Published: Feb. 25, 2022

The high glutathione (GSH) content in tumor cells strongly affects the efficiency of chemodynamic therapy (CDT). Despite devoted efforts, it still remains a formidable challenge for manufacturing tumor-specific CDT with rapid and thorough depletion GSH. Herein, multistage GSH-consuming is presented. By consuming reserved GSH inhibiting both raw materials energy supply synthesis cancer cells, achieves highly potent exhaustion. Our used glycolysis inhibitor cuts off specific to increase sensitivity CDT. Furthermore, starvation effect can stimulate protective mode normal cells. Since nanocarrier are responsive microenvironment, this makes more selective work not only fabricates nanomedicine exhausted function but also uses metabolic differences achieve therapy.

Gas therapy potentiates aggregation-induced emission luminogen-based photoimmunotherapy of poorly immunogenic tumors through cGAS-STING pathway activation

The immunologically "cold" microenvironment of triple negative breast cancer results in resistance to current immunotherapy. Here, we reveal the immunoadjuvant property gas therapy with cyclic GMP-AMP synthase-stimulator interferon genes (cGAS-STING) pathway activation augment aggregation-induced emission (AIE)-active luminogen (AIEgen)-based photoimmunotherapy. A virus-mimicking hollow mesoporous tetrasulfide-doped organosilica is developed for co-encapsulation AIEgen and manganese carbonyl fabricate nanoadjuvant. As tetra-sulfide bonds are responsive intratumoral glutathione, nanoadjuvant achieves tumor-specific drug release, promotes photodynamic therapy, produces hydrogen sulfide (H2S). Upon near-infrared laser irradiation, AIEgen-mediated phototherapy triggers burst carbon monoxide (CO)/Mn2+. Both H2S CO can destroy mitochondrial integrity induce leakage DNA into cytoplasm, serving as immunoadjuvants activate cGAS-STING pathway. Meanwhile, Mn2+ sensitize cGAS STING-mediated type I production. Consequently, potentiates photoimmunotherapy poorly immunogenic tumors female mice.

Journal of the American Chemical Society, Journal Year: 2022, Volume and Issue: 144(11), P. 4799 - 4809

Chemodrug resistance is a major reason accounting for tumor recurrence. Given the mechanistic complexity of chemodrug resistance, molecular inhibitors and targeting drugs often fail to eliminate drug-resistant cancer cells, sometimes even promote chemoresistance by activating alternative pathways. Here, exploiting biochemical fragility high-level but dynamically balanced cellular redox homeostasis in we design nanosized copper/catechol-based metal-organic framework (CuHPT) that effectively disturbs this tilting balance toward oxidative stress. Within CuHPT starts disassembly triggered persistent consumption glutathione (GSH). simultaneously releases two structural elements: catechol ligands reductive copper ions (Cu+). Both them cooperatively function amplify production intracellular radical species (ROS) via auto-oxidation Fenton-like reactions through exhausting GSH. By drastically heightening stress, exhibits selective potent cytotoxicity multiple cells. Importantly, inhibits vivo growth doubles survival time tumor-bearing mice. Thus, along with CuHPT's good biocompatibility, our biochemical, cell biological, preclinical animal model data provide compelling evidence supporting notion copper-based MOF predesigned smart therapeutic against cancers precisely deconstructing their homeostasis.
