A facile strategy to construct dual-drug delivery nanoparticles (), which possessed higher loading content of CPT and TPP-LND. Notably, showed promising ultrarapid pH/GSH response to release more than 86% of loaded TPP-LND or 93% of loaded CPT in just 2 h. The results showed that the nanoparticles hierarchically delivered CPT and TPP-LND to targeted different organelles without mutual influence benefiting the ultrarapid pH/GSH response to drug release, and further significantly and synergistically induced cell apoptosis and improved chemotherapeutic efficiency in cancer cells.

Chemodynamic therapy (CDT) has garnered significant attention in the field of tumor therapy due to its ability to convert overexpressed hydrogen peroxide (HO) in tumors into highly toxic hydroxyl radicals (•OH) through metal ion-mediated catalysis. However, the effectiveness of CDT is hindered by low catalyst efficiency, insufficient intra-tumor HO level, and excessive glutathione (GSH). In this study, a pH/GSH dual responsive bimetallic nanocatalytic system (CuFeMOF@GOx@Mem) is developed by modifying red blood cell membranes onto glucose oxidase (GOx)-loaded Fe-Cu bimetallic MOFs, enhancing the efficacy of CDT through a triple-enhanced way by HO self-supply, catalysts self-cycling, and GSH self-elimination.

In this study, the mesoporous FeO nanodrug carriers containing disulfide bonds (CHO-SMNPs) were successfully synthesized and characterized. Doxorubicin (DOX) was loaded onto the CHO-SMNPs as a model drug and gatekeeper through the formation of imine bonds with the aldehyde groups on the surface of the mesoporous materials. This drug carrier demonstrates effective drug release triggered by pH, glutathione (GSH), and near-infrared (NIR) light, along with satisfactory photothermal conversion efficiency under NIR irradiation at 808 nm.

Epigenetic regulation has emerged as a promising therapeutic strategy for lung cancer treatment, which can facilitate the antitumor responses by modulating epigenetic dysregulation of target proteins in lung cancer. The proteolysis-targeting chimera (PROTAC) reagent, dBET6 shows effective inhibition of bromodomain-containing protein 4 (BRD4) that exerts antitumor efficacy by degrading BRD4 via the ubiquitin-proteasome system. Nevertheless, the low tissue specificity and bioavailability impede its therapeutic effects and clinical translation on lung cancer treatment.

Dihydroartemisinin (DHA), a compound extracted from the herbal medicine Artemisia annua, has shown promise as a clinical treatment strategy for colorectal cancer. However, its clinical use is hindered by its low water solubility and bioavailability. A pH/glutathione (GSH) dual-responsive nano-herb delivery system (PMDC NPs) has been developed for the targeted delivery of DHA, accompanied by abundant carbon monoxide (CO) release.

Targeted nanodrug delivery systems are highly anticipated for the treatment of malaria. It is known that can induce new permeability pathways (NPPs) on the membrane of infected red blood cells (iRBCs) for their nutrient uptake. The NPPs also enable the uptake of nanoparticles (NPs) smaller than 80 nm.
