Cancer treatment is currently one of the most critical healthcare issues globally. A well-designed drug delivery system can precisely target tumor tissues, improve efficacy, and reduce damage to normal tissues. Stimuli-responsive systems (SRDDSs) have shown promising application prospects. Intelligent nano responsive endogenous stimuli such as weak acidity, complex redox characteristics, hypoxia, active energy metabolism, well exogenous like high temperature, light, pressure, magnetic fields are increasingly being applied in chemotherapy, radiotherapy, photothermal therapy, photodynamic various other anticancer approaches. Metal–organic frameworks (MOFs) become candidate materials for constructing SRDDSs due their large surface area, tunable porosity structure, ease synthesis modification, good biocompatibility. This paper reviews MOF-based modes cancer therapy. It summarizes key aspects, including classification, synthesis, modifications, loading modes, stimuli-responsive mechanisms, roles different modalities. Furthermore, we address current challenges summarize potential applications artificial intelligence MOF synthesis. Finally, propose strategies enhance efficacy safety SRDDSs, ultimately aiming at facilitating clinical translation.

Abstract Sonodynamic therapy (SDT), featuring noninvasive, deeper penetration, low cost, and repeatability, is a promising approach for deep‐seated tumors. However, the general or only utilization of SDT shows efficiency unsatisfactory treatment outcomes due to complicated tumor microenvironment (TME) process. To circumvent issues, three feasible approaches enhancing SDT‐based therapeutic effects, including sonosensitizer optimization, strategies conquering hypoxia TME, combinational are summarized, with particular focus on combination other modalities, chemodynamic therapy, photodynamic photothermal chemotherapy, starvation gas immunotherapy. In end, current challenges in tumors discussed enhanced effects provided. It envisioned that this review will provide new insight into strategic design high‐efficiency sonosensitizer‐derived nanotheranostics, thereby augmenting accelerating potential clinical transformation.

Metal peroxide nanomaterials as efficient hydrogen (H2O2) self-supplying agents have attracted the attention of researchers for antitumor treatment. However, relying solely on metal peroxides to provide H2O2 is undoubtedly insufficient achieve optimal effects. Herein, we construct novel hyaluronic acid (HA)-modified nanocomposites (MgO2/Pd@HA NCs) formed by decorating palladium nanoparticles (Pd NPs) onto surfaces a magnesium (MgO2) nanoflower highly effective nanoplatform tumor microenvironment (TME)-responsive induction ferroptosis in cells and photothermal therapy (PTT). MgO2/Pd@HA NC could be well endocytosed into with CD44 expression depending specific recognition HA CD44, then, can rapidly decomposed mild hyaluronidase overexpressed TME, plenty was released. Simultaneously, Pd NPs catalyze self-supplied generate abundant hydroxyl radicals (•OH) glutathione (GSH) disulfide owing its peroxidase oxidase mimic enzyme activities, while •OH also consume GSH disturb defense pathways leading accumulation lipid peroxidation resulting occurrence ferroptosis.

Radiofrequency ablation (RFA), a critical therapy for hepatocellular carcinoma (HCC), carries significant risk of recurrence and metastasis, particularly owing to mechanisms involving immune evasion antigen downregulation via epigenetic modifications. This study introduces "nano-epidrug" named MFMP. MFMP, which is composed hollow mesoporous manganese dioxide (MnO2) nanoparticles, FIDAS-5 as an MAT2A inhibitor, macrophage membrane, anti-PD-L1 (aPD-L1), targets HCC cells. By selectively binding these cells, MFMP initially reverses suppression PD-L1 inhibition. After endocytosis, disassembles in the tumor microenvironment, releasing Mn2+. prevents cGAS methylation, whereas Mn2+ aids STING pathway restoration. In addition, reduces m6A RNA modification, suppressing EGFR expression. These changes enhance antigenicity promote cytotoxic T cell recognition killing. Furthermore, mediates immunogenic death by synergizing with RFA through DNA demethylation, mRNA TBK1 protein phosphorylation, thereby inhibiting metastasis enhancing memory. Thus, potential adjunctive requiring clinical validation.
