Abstract Ferroptosis is a new form of regulated cell death featuring iron‐dependent lipid peroxides accumulation to kill tumor cells. A growing body evidence has shown the potential ferroptosis‐based cancer therapy in eradicating refractory malignancies that are resistant apoptosis‐based conventional therapies. In recent years, studies have reported number ferroptosis inducers can increase vulnerability cells by regulating ferroptosis‐related signaling pathways. Encouraged rapid development ferroptosis‐driven therapies, interdisciplinary fields combine ferroptosis, pharmaceutical chemistry, and nanotechnology focused. First, prerequisites metabolic pathways for briefly introduced. Then, detail emerging designed boost ferroptosis‐induced therapy, including metal complexes, metal‐based nanoparticles, metal‐free nanoparticles summarized. Subsequently, application synergistic strategies with apoptosis other emphasis on use both cuproptosis induce redox dysregulation intracellular bimetallic copper/iron metabolism disorders during treatment discussed. Finally, challenges associated clinical translation future directions potentiating therapies highlighted.

A Multifunctional Covalent Organic Framework Nanozyme for Promoting Ferroptotic Radiotherapy against Esophageal Cancer

ACS Nano, Год журнала: 2023, Номер 17(20), С. 20445 - 20461

Опубликована: Окт. 6, 2023

Radiotherapy is inevitably accompanied by some degree of radiation resistance, which leads to local recurrence and even therapeutic failure. To overcome this limitation, herein, we report the room-temperature synthesis an iodine- ferrocene-loaded covalent organic framework (COF) nanozyme, termed TADI-COF-Fc, for enhancement radiotherapeutic efficacy in treatment radioresistant esophageal cancer. The iodine atoms on COF not only exerted a direct effect radiotherapy, increasing its X-ray absorption, but also promoted radiolysis water, increased production reactive oxygen species (ROS). In addition, ferrocene surface decoration disrupted redox homeostasis levels hydroxyl lipid peroxide radicals depleting intracellular antioxidants. Both vitro vivo experiments substantiated excellent response TADI-COF-Fc. This study demonstrates potential COF-based multinanozymes as radiosensitizers suggests possible integration strategy combination oncotherapy.

Selenium‐Doped Nanoheterojunctions for Highly Efficient Cancer Radiosensitization

Advanced Science, Год журнала: 2024, Номер 11(29)

Опубликована: Июнь 3, 2024

Abstract Exploring efficient and low‐toxicity radiosensitizers to break through the bottleneck of radiation tolerance, immunosuppression poor prognosis remains one critical developmental challenges in radiotherapy. Nanoheterojunctions, due their unique physicochemical properties, have demonstrated excellent radiosensitization effects energy deposition lifting tumor radiotherapy inhibition. Herein, they doped selenium (Se) into prussian blue (PB) construct a nano‐heterojunction (Se@PB), which could promote increase Fe 2+ /Fe 3+ ratio conversion Se high valence state with introduction. The ‐Se‐Fe electron transfer chain accelerates rate on surface nanoparticles, turn endows it X‐ray transport capability, enhances physical sensitivity. Furthermore, Se@PB induces glutathione (GSH) depletion accumulation pro‐Fenton reaction, thereby disturbs redox balance cells biochemical sensitivity As an radiosensitizer, effectively induced mitochondrial dysfunction DNA damage, promotes cell apoptosis synergistic cervical cancer This study elucidates mechanism Se‐doped nanoheterojunction from perspective biochemistry provides low‐toxic strategy
