Naphthalene endoperoxides undergo thermal cycloreversion reactions to produce singlet oxygen and their parent naphthalene compounds. The rate of the reaction is dependent on the structural features, such as steric and electronic modulators. We believe that achieving a sustained release rate of singlet oxygen is important in potential biological applications. This can be achieved by tethering of two endoperoxides with different singlet oxygen release rates in a single molecular construct. Here, we report the synthesis of such a dimeric endoperoxide. Our data shows that with the biexponential reaction kinetics of singlet oxygen generation from a heterodimeric endoperoxide, it is possible to hold singlet oxygen release rates within a selected range for a longer period of time.

The efficacy of photodynamic treatment (PDT) against deep-seated tumor is hindered by low penetration depth of light as well as hypoxic conditions which prevails in tumor. To overcome this limitation, Near-infrared (NIR) absorbing photosensitizers have been investigated actively. In the present study we evaluated the PDT efficacy of an NIR absorbing chlorophyll derivative 'Cycloimide Purpurin-18 (CIPp-18)' in Human Breast carcinoma (MCF-7) and cervical adenocarcinoma (Hela) cells under normoxic and hypoxic conditions.

Non-metallic iodine single-atom catalysts with optimized electronic structures for efficient Fenton-like reactions.

In this study, we introduce a highly effective non-metallic iodine single-atom catalyst (SAC), referred to as I-NC, which is strategically confined within a nitrogen-doped carbon (NC) scaffold. This configuration features a distinctive C-I coordination that optimizes the electronic structure of the nitrogen-adjacent carbon sites. As a result, this arrangement enhances electron transfer from peroxymonosulfate (PMS) to the active sites, particularly the electron-deficient carbon.

Ligand-functionalized InP-based quantum dots (QDs) have been developed as an innovative class of nontoxic photosensitizer suitable for antimicrobial applications, aimed at reducing or preventing pathogen transmission from one host to another via high contact surfaces. A hot injection method followed by functionalization via ligand exchange with 9-anthracene carboxylic acid (ACA) yielded the desired core/shell InP/ZnSe/ZnS QDs. Transmission electron microscopy (TEM) revealed these QDs to be uniform in size (∼3.

Biodegradable Vanadium-Based Nanomaterials for Photothermal-Enhanced Tumor Ferroptosis and Pyroptosis.

ACS Appl Mater Interfaces

The designability and high reactivity of nanotechnology provide strategies for antitumor therapy by regulating the redox state in tumor cells. Here, we synthesize a kind of vanadium dioxide nanoparticle encapsulated in bovine serum albumin and containing disulfide bonds (VSB NPs) for photothermal-enhanced ferroptosis and pyroptosis effects. Mechanism studies show that disulfide bonds can effectively consume overexpressed glutathione (GSH) in the tumor microenvironment, leading to a decrease in glutathione peroxidase 4 (GPX4) activity.

Mechanistic insight into multiple effects of copper ion on the photoreactivity of dissolved organic matter.

Sunlight irradiation of dissolved organic matter (DOM) in surface water results in the production of photochemically produced reactive intermediates (PPRIs). This process is inevitably influenced by co-existing metal ions in aquatic environments; However, the underlying mechanism remains unclear. In this study, the effect of co-existing copper ion (Cu) on PPRIs produced by irradiation of DOM was systematically investigated, because Cu is a typical redox transient cation and has strong affinity to DOM.
