In the quest for powerful, safe, and storable photoinduced-electron transfer (PET) donors, the attention is turned to the α-trihalomethylated amine moiety that is not studied in the context of PET-reductants. The thermal and photophysical properties of α-trifluoromethylated quinolines are thus studied and their reducing abilities evaluated as initiators of polymerization reactions. Polymers of high molecular weights are obtained through a radical polymerization process and the PET-donor can be stored within the monomer for several months without losing its efficiency. Mechanistic investigations, combining spectroscopic analysis and theoretical calculations, confirm the mode of activation of these electron donors and the generation of radical intermediates through single electron transfer.

Background: The excessive application of enrofloxacin (ENR) results in residues contaminating both food and the environment. Consequently, developing robust analytical methods for the selective detection of ENR is crucial. The photoelectrochemical (PEC) sensor has emerged as a highly sensitive analytical technique that has seen rapid development in recent years.

Hypoxic tumors present a significant challenge in cancer therapy due to their ability to adaptation in low-oxygen environments, which supports tumor survival and resistance to treatment. Enhanced mitophagy, the selective degradation of mitochondria by autophagy, is a crucial mechanism that helps sustain cellular homeostasis in hypoxic tumors. In this study, we develop an azocalix[4]arene-modified supramolecular albumin nanoparticle, that co-delivers hydroxychloroquine and a mitochondria-targeting photosensitizer, designed to induce cascaded oxidative stress by regulating mitophagy for the treatment of hypoxic tumors.

Infectious diseases caused by drug-resistant bacteria represent one of the most significant global public challenges of this century. There is an urgent need for the treatment of drug-resistant Gram-negative bacterial infections. A series of 3,4-dihydro-2H-[1,3]oxazino[5,6-h]quinoline derivatives were synthesized and evaluated for their antibacterial activity against Gram-negative bacteria including strains from ATCC and clinical isolates, initially revealing the structure-activity relationship.

Inflammatory skin diseases comprise a group of skin conditions characterized by damage to skin function due to overactive immune responses. These disorders not only impair the barrier function of the skin but also deteriorate the quality of life and increase the risk of psychiatric issues. Here, a low-modulus phosphatidylserine-exposing microvesicle (deformed PSV, D-PSV) was produced, characterized, and evaluated for its potential therapeutic function against skin diseases.
