Singlet oxygen was produced in chemical reaction NaClO+ H2O2. Action of different well-known anti-cataract drugs on this reaction was studied. There is no doubt that the singlet oxygen chemiluminescence decreases in the presence of Catalin and Baineiting. Finnish Catachrom Ophthan, Vita iodurol (France) and Quinax (USA) have no such effect at all which may be a result of the interaction of these remedies with H2O2 and/or with NaClO.

Agricultural Product Processing and Storage Lab, School of Food and Biological Engineering, Jiangsu University, Zhenjiang, Jiangsu 212013, China. Electronic address:

The current study aimed to synthesize a ZIF-8 metal-organic framework loaded with the Rose Bengal (ZIF-8@RB) as the photodynamic sterilization ingredient to address the uncontrolled release of active ingredients in packaging films. The photodynamic controlled release packaging film was then prepared using a PVDF polymer matrix via uniaxial electrospinning. The microstructure, particle size, excitation wavelength, and singlet oxygen yield of ZIF-8@RB were examined.

Dual Pathways of Photorelease Carbon Monoxide via Photosensitization for Tumor Treatment.

R. China.

Carbon monoxide (CO) gas therapy, as an emerging therapeutic strategy, is promising in tumor treatment. However, the development of a red or near-infrared light-driven efficient CO release strategy is still challenging due to the limited physicochemical characteristics of the photoactivated carbon monoxide-releasing molecules (photoCORMs). Here, we discovered a novel photorelease CO mechanism that involved dual pathways of CO release via photosensitization.

Photooxidation and Cleavage of Ethynylated 9,10-Dimethoxyanthracenes with Acid-Labile Ether Bonds.

J Org Chem

January 2025

Department of Chemistry, Tufts University, 62 Talbot Avenue, Medford, Massachusetts, 02155, United States.

This paper describes a series of 12 9,10-dimethoxyanthracene derivatives functionalized with a range of electronically diverse ethynyl substituents at the 2 and 6 positions, aimed at tuning their optoelectronic properties and reactivity with singlet oxygen (O). Optical spectroscopy, cyclic voltammetry, and density functional theory calculations reveal that the ethynyl groups decrease the HOMO-LUMO gaps in these acenes. Notably, bis(dimethylanilineethynyl) substituents increase the wavelength of absorbance onset by over 60 nm compared to 9,10-dimethoxyanthracene (DMA).

Decreasing the aggregation of photosensitizers to facilitate energy transfer for improved photodynamic therapy.

Nanoscale

January 2025

Institute of Hepatobiliary and Pancreatic Surgery, Department of Hepatobiliary and Pancreatic Surgery, Shanghai East Hospital, School of Medicine, Tongji University, Shanghai, 200120, P. R. China.

The mode of energy transfer between photosensitizers and oxygen determines the yield of singlet oxygen (O), crucial for photodynamic therapy (PDT). However, the aggregation of photosensitizers promotes electron transfer while inhibiting pure energy transfer, resulting in the generation of the hypotoxic superoxide anion (O) and consumption of substantial oxygen. Herein, we achieve the reduction of the aggregation of photosensitizers to inhibit electron transfer through classical chemical crosslinking, thereby boosting the production of O.

Adverse drug reactions (ADR) remain a challenge in modern healthcare, particularly given the increasing complexity of therapeutics. WHO's definition of an adverse drug reaction as a response to a drug that is noxious and unintended and occurs at doses normally used in man for the prophylaxis, diagnosis or therapy of disease, or for modification of physiological function. This definition underscores the importance of monitoring and mitigating unintended drug effects, particularly for widely used medications like valproic acid (VPA).
