Protease inhibitors can modulate intratumoral metabolic processes to reprogram the immunosuppressive tumor microenvironment (TME), which however suffer from limited efficacy and off-targeted side effects. We report smart nano-proteolysis targeting chimeras (nano-PROTACs) with phototherapeutic ablation cancer-specific protein degradation TME for photo-metabolic cancer immunotherapy. This nano-PROTAC has a semiconducting polymer backbone linked cyclooxygenase 1/2 (COX-1/2)-targeting PROTAC peptide (CPP) via cathepsin B (CatB)-cleavable segment. CPP be activated by tumor-overexpressed CatB induce of COX-1/2 ubiquitin-proteasome system. The persistent depletes their metabolite prostaglandin E2 is responsible activation immune suppressor cells. Such strategy synergized phototherapy specifically reprograms reinvigorates antitumor immunity.

Abstract Although immunotherapy has revolutionized cancer therapy by providing efficient tumor growth suppression, long‐term protection from recurrence as well minimized side effects, the low response rate significantly limits clinical application of in board types solid tumors. In order to improve therapeutic efficacy, conventional therapies including radiotherapy, chemotherapy, phototherapy and chemodynamic are employed combine with elicit stronger antitumor immune responses. Polymer nanomedicines frequently utilized synergistic other owing their tunable physiochemical properties, high drug loading capacity, ease modification toxicity. With elaborate design tailored polymer can enhance efficacy enhancing specificity, priming cells amplifying responses However, until now, there is no review solely dedicated comprehensive development polymer‐based platforms for combinational cancers. Herein, this paper summarizes latest advances design, fabrication traditional strategies photothermal therapy, photodynamic therapies. An outlook on trajectory potential challenges bridging gap between also discussed.

Abstract Mild photothermal therapy (PTT) is an emerging and elegant approach with minimal adverse effects, demonstrating itself as effective treatment for cancer. However, potential challenges may arise from the overexpression of heat shock protein 90 (HSP90) reliance on monotherapy. Here, a near‐infrared (NIR) light‐triggered MXene nanocomposite (FA@MXene/CuO 2 /GA) developed to synergistically combine mild PTT chemodynamic (CDT) remarkably tumor eradication without any notable tissue damage. Under irradiation NIR light, effectively enhances by suppressing HSP90 expression through release gambogic acid (GA) due excellent performance Ti 3 C nanosheets well tumor‐targeting ability biocompatibility surface‐modified FA‐PEG‐SH. The copper‐based catalyst CuO in this system releases Cu 2+ acid‐triggered manner within microenvironment, activating Fenton‐like reaction generate hydroxyl radicals, simultaneous production H O serves alleviate deficiency endogenous tumor. Overall, current work showcases remarkable synergistic anticancer effect CDT, also proposes new avenues research utilizing nanomaterials treatment.

Abstract Photodynamic therapy (PDT) and photothermal (PTT) have emerged as promising treatment options, showcasing immense potential in addressing both oncologic nononcologic diseases. Single‐component organic phototherapeutic agents (SCOPAs) offer advantages compared to inorganic or multicomponent nanomedicine, including better biosafety, lower toxicity, simpler synthesis, enhanced reproducibility. Nonetheless, how further improve the therapeutic effectiveness of SCOPAs remains a challenging research area. This review delves deeply into strategies performance PDT PTT by optimizing structural design SCOPAs. These encompass augmenting reactive oxygen species (ROS) generation, mitigating dependence, elevating light absorption capacity, broadening region, enhancing conversion efficiency (PCE). Additionally, this also underscores ideal for developing with balanced PTT. Furthermore, synergies are highlighted between other modalities such ferroptosis, gas therapy, chemotherapy, immunotherapy. By providing comprehensive analysis these strategies, aspires serve valuable resource clinicians researchers, facilitating wider application advancement SCOPAs‐mediated
