Abstract The treatment of brain diseases has always been the focus attention. Due to presence blood‐brain barrier (BBB), most small molecule drugs are difficult reach brain, leading undesirable therapeutic outcomes. Recently, nanomedicines that can cross BBB and precisely target lesion sites have emerged as thrilling tools enhance early diagnosis treat various intractable disorders. Extensive research shown reactive oxygen species (ROS) play a crucial role in occurrence progression diseases, including tumors neurodegenerative (NDDs) such Alzheimer's disease, Parkinson's stroke, or traumatic injury, making ROS potential target. In this review, on structure function well mechanisms first elaborated through which nanomedicine traverses it. Then, recent studies production summarized photodynamic therapy (PDT), chemodynamic (CDT), sonodynamic (SDT) for treating tumors, depletion NDDs. This provides valuable guidance future design ROS‐targeted disease treatment. ongoing challenges perspectives developing nanomedicine‐based management also discussed outlined.

Low-intensity ultrasound-mediated sonodynamic therapy (SDT), which, by design, integrates sonosensitizers and molecular oxygen to generate therapeutic substances (e.g., toxic hydroxyl radicals, superoxide anions, or singlet oxygen) at disease sites, has shown enormous potential for the effective treatment of a variety diseases. Nanoscale play crucial role in SDT process because their structural, compositional, physicochemical, biological characteristics are key determinants efficacy. In particular, advances materials science nanotechnology have invigorated series optimization strategies augmenting efficacy nanosonosensitizers. This comprehensive review systematically summarizes, discusses, highlights state-of-the-art studies on current achievements nanosonosensitizer enhanced treatment, with an emphasis general design principles nanosonosensitizers strategies, mainly including organic inorganic Additionally, recent advancements optimized applications aimed treating various diseases, such as cancer, bacterial infections, atherosclerosis, autoimmune clarified detail. Furthermore, effects improved versatile thoroughly discussed. The concludes highlighting challenges future opportunities this rapidly evolving research field expedite its practical clinical translation application.

Glioblastoma multiforme (GBM) is the most aggressive and lethal subtype of gliomas central nervous system. The efficacy sonodynamic therapy (SDT) against GBM significantly reduced by expression apoptosis-inhibitory proteins in cells. In this study, an intelligent nanoplatform (denoted as Aza-BD@PC NPs) based on aza-boron-dipyrromethene dye phenyl chlorothionocarbonate-modified DSPE-PEG molecules developed for synergistic ferroptosis-enabled gas (GT) SDT GBM.

Aberrant proliferation and inflammation of fibroblast-like synoviocytes (FLSs) significantly contribute to the pathogenesis rheumatoid arthritis (RA). Deficiency hydrogen sulfide (H2S) is a driving force for development RA, short half-life H2S-releasing donor sodium hydrosulfide (NaHS) limits its clinical application in RA therapy. Designing targeted delivery system with slow-release properties FLSs could offer novel strategies treating RA. Herein, we designed strategy achieve slow release H2S synovium, which was accomplished by synthesizing NaHS-CY5@mesoporous silic@LNP peptide Dil (NaHS@Cy5@MS@SP) nanoparticles. Our results demonstrated that NaHS@Cy5@MS@SP effectively targets FLSs, upregulates its-producing enzyme cystathionine-γ-lyase (CSE) joints arthritic mice. Overexpression CSE inhibited proliferation, migration, upon lipopolysaccharide (LPS) exposure, effects were mimicked NaHS@Cy5@MS@SP. In vivo studies showed achieved threefold higher AUCinf than free NaHS, improving bioavailability NaHS. Further, synovial hyperplasia reduced bone cartilage erosion DBA/1J mouse model collagen-induced (CIA), superior RNA sequencing molecular validated inactivated Hedgehog signaling pathway as evidenced reductions protein expression SHH, SMO, GLI1 phosphorylated p38/MAPK. This study highlights promising controlled synoviocytes, offering potential management.

Abstract Tuning the oxidative stress‐defense system plays a vital role in treatment of breast tumors. In this study, pyropheophorbide‐a (PPa)‐based prodrug nanoassembly is constructed by linking PPa with furoxan, cysteine‐depleting nitric oxide (NO) donor, through disulfide bond. The as‐prepared (NOSP) can assemble distearoyl phosphoethanolamine‐PEG 2000 (DSPE‐PEG ) to form nanoassemblies aqueous media. Following internalization tumor cells, NOSP respond cysteine (Cys) and induce NO release activate endogenous matrix metalloproteinases (MMP‐1, ‐2), leading collagen degradation improved drug delivery. addition, Cys consumption impede biosynthesis glutathione (GSH), while react high levels intracellular GSH within seconds, thus synergizing photodynamic therapy against tumors distant metastasis.
