Abstract Suffering from the laborious synthesis and undesirable tumor microenvironment response, exploitation of novel NIR‐II absorbing organic photothermal agents is importance to promote phototherapeutic efficacy. Herein, two kinds charge‐transfer complex nanoparticles (TMB‐F4TCNQ TMB‐TCNQ) are prepared by supramolecular assembly. Because larger energy gap between donor acceptor, TMB‐F4TCNQ presents higher degree (72 %) than that TMB‐TCNQ (48 in nanoaggregates. Therefore, exhibits stronger absorption ability with a mass extinction coefficient 15.4 Lg −1 cm at 1300 nm excellent effect. Impressively, specific cysteine response can make effectively inhibit intracellular biosynthesis GSH, leading redox dsyhomeostasis ROS‐mediated ferroptosis. serve as contrast agent for photoacoustic imaging guide precise efficient therapy vivo.

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. This review introduces latest advancements nanomaterials‐involved from 2018 present proposes current limitations well future research directions related

ConspectusNanozymes, which integrate the advantages of both nanomaterials and natural enzymes, have accumulated enormous research interest over past decades because opportunity they provide to appreciate further cultivate artificial enzymes with comparable properties. By mimicking coordination environments catalytic sites in nanozymes confined nanostructures can serve as substitutes many processes activity robust stability even harsh conditions. Since pioneering report about peroxidase-mimicking ferromagnetic nanoparticles 2007, been developed specialized for intrinsic enzyme-mimicking property. With rapid development nanoscience nanotechnology, superior advantages, such large-scale production, desired activity, stability, bridge nanozymes.Metal–organic frameworks (MOFs) their derivatives hold great promise direct surrogates conventional enzymatic reactions. According chemical nature, MOF-based be divided into three main categories: pristine MOFs, enzyme-encapsulated MOF composites, derivatives. Due versatility metallic nodes bridging linkers together feasibility postsynthetic engineering modification, MOFs are envisioned one most appropriate this purpose. Using precursors or sacrificial templates, multiple including carbon-based (e.g., heteroatom-doped carbon M–N–C moiety), metal oxide/carbon nanoparticles, metal/carbon rationally synthesized through one-step carbonization/oxidation indirect post-synthesis treatments linker-exchange node-doping). Compared existing nanozymes, open up a new avenue constructing mesoporous nanozymes. In way, properties still maintained, while greatly improved. Account, we highlight some important advances (including moieties (M = single atom), oxide/carbon, metal/carbon, obtained linker exchange doping strategies) activity. We also demonstrate that, integrating physicochemical activities MOF-derived multifunctional platforms biomedical fields antibacterial agents, biosensors, imaging, cancer therapy, environmental protection. Finally, propose future design principles possible approaches deeper understanding mechanisms, thus pointing out directions offer more opportunities enzyme-engineering industry.

Chemodynamic therapy (CDT) uses the tumor microenvironment-assisted intratumoral Fenton reaction for generating highly toxic hydroxyl free radicals (•OH) to achieve selective treatment. However, limited efficiency restricts therapeutic efficacy of CDT. Recent years have witnessed impressive development various strategies increase reaction. The introduction these reinforcement can dramatically improve treatment CDT and further promote enhanced (ECDT)-based multimodal anticancer treatments. In this review, authors systematically introduce strategies, from their basic working principles, mechanisms representative clinical applications. Then, ECDT-based is discussed, including how integrate emerging accelerating therapy, as well synergistic ECDT other methods. Eventually, future direction challenges therapies are elaborated, highlighting key scientific problems unsolved technical bottlenecks facilitate translation.

Abstract Reactive oxygen species (ROS) and reactive nitrogen (RNS) are well recognized for playing a dual role, since they can be either deleterious or beneficial to biological systems. An imbalance between ROS production elimination is termed oxidative stress, critical factor common denominator of many chronic diseases such as cancer, cardiovascular diseases, metabolic neurological disorders (Alzheimer’s Parkinson’s diseases), other disorders. To counteract the harmful effects ROS, organisms have evolved complex, three-line antioxidant defense system. The first-line mechanism most efficient involves enzymes superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx). This line plays an irreplaceable role in dismutation radicals (O 2 ·− ) hydrogen peroxide (H O ). removal by SOD prevents formation much more damaging peroxynitrite ONOO − + NO · → maintains physiologically relevant level nitric oxide (NO ), important molecule neurotransmission, inflammation, vasodilation. second-line pathway exogenous diet-derived small-molecule antioxidants. third-line ensured repair oxidized proteins biomolecules variety enzyme review briefly discusses endogenous (mitochondria, NADPH, xanthine oxidase (XO), Fenton reaction) (e.g., smoking, radiation, drugs, pollution) sources (superoxide radical, peroxide, hydroxyl peroxyl hypochlorous acid, peroxynitrite).

Cancer cells frequently exhibit resistance to various molecular and nanoscale drugs, which inevitably affects the drugs' therapeutic outcomes. Overexpression of glutathione (GSH) has been observed in many cancer cells, solid evidence corroborated resulting tumor a variety anticancer therapies, suggesting that this biochemical characteristic can be developed as potential target for treatments. The single treatment GSH-depleting agents potentiate responses different cell death stimuli; therefore, an adjunctive strategy, GSH depletion is usually combined with mainstream therapies enhancing Propelled by rapid development nanotechnology, readily constructed into nanomedicines, have shown steep rise over past decade. Here, we review common nanomedicines widely applied synergistic treatments recent years. Some current challenges future perspectives depletion-based are also presented. With understanding structure–property relationship action mechanisms these biomaterials, hope nanotechnology will further realize more effective disease even achieve successful clinical translations.
