Опубликована: Янв. 3, 2023

Abstract Covalent organic frameworks (COFs) have attracted increasing attention for biomedical applications. COFs‐based nanosensitizers with uniform nanoscale morphology and tumor‐specific curative effects are in high demand; however, their synthesis is yet challenging. In this study, distinct COF nanobowls synthesized a controlled manner engineered as activatable sonodynamic activity. High crystallinity ensures an ordered porous structure of the efficient loading small‐molecule sonosensitizer rose bengal (RB). To circumvent non‐specific damage to normal tissues, sonosensitization effect specifically inhibited by situ growth manganese oxide (MnO x ) on RB‐loaded COFs. Upon reaction tumor‐overexpressed glutathione (GSH), “gatekeeper” MnO rapidly decomposed recover reactive oxygen species (ROS) generation capability under ultrasound irradiation. Increased intracellular ROS stress GSH consumption concomitantly induce ferroptosis improve efficacy. Additionally, unconventional bowl‐shaped renders enhanced tumor accumulation retention. The combination therapy achieves efficacy killing cancer cells inhibiting growth. This study paves way development morphologies biomedicine, offering paradigm realize ferroptosis‐augmented therapy.

The development of covalent organic framework (COF) sonosensitizers with intrinsic sonodynamic effects is highly desirable. However, such COFs are generally constructed using small-molecule photosensitizers. Herein, we report that the reticular chemistry-based synthesis from two inert monomers yields a COF-based sonosensitizer (TPE-NN) inherent activity. Subsequently, nanoscale COF TPE-NN fabricated and embedded copper (Cu)-coordinated sites to obtain TPE-NN-Cu. Results show Cu coordination can enhance effect TPE-NN, whereas ultrasound (US) irradiation for therapy augment chemodynamic efficacy Consequently, TPE-NN-Cu upon US shows high-performance anticancer based on mutually reinforced sono-/chemo-nanodynamic therapy. This study reveals backbone-originated activity proposes paradigm nanodynamic

Spatially Asymmetric Nanoparticles for Boosting Ferroptosis in Tumor Therapy

Nano Letters, Год журнала: 2024, Номер 24(4), С. 1284 - 1293

Опубликована: Янв. 17, 2024

Despite its effectiveness in eliminating cancer cells, ferroptosis is hindered by the high natural antioxidant glutathione (GSH) levels tumor microenvironment. Herein, we developed a spatially asymmetric nanoparticle, Fe3O4@DMS&PDA@MnO2-SRF, for enhanced ferroptosis. It consists of two subunits: Fe3O4 nanoparticles coated with dendritic mesoporous silica (DMS) and PDA@MnO2 (PDA: polydopamine) loaded sorafenib (SRF). The spatial isolation Fe3O4@DMS PDA@MnO2-SRF subunits enhances synergistic effect between GSH-scavengers ferroptosis-related components. First, increased exposure subunit Fenton reaction, leading to production reactive oxygen species. Furthermore, effectively depletes GSH, thereby inducing inactivation glutathione-dependent peroxidases 4. Moreover, SRF blocks Xc– transport augmenting GSH depletion capabilities. dual Fe3O4@DMS&PDA@MnO2-SRF significantly weakens antioxidative system, boosting chemodynamic performance cells.
