Trithio‐naphthalic anhydride‐based photosensitizer for photodynamic activity

Bulletin of the Korean Chemical Society, EarlyView.
A trithio‐naphthalic anhydride photosensitizer (NapS) is created by simple thionation, switching excited‐state pathways to deliver both type I and type II reactive oxygen species. NapS enables efficient photodynamic therapy under normoxia and hypoxia, achieving strong cancer cell killing with low dark toxicity.

Singlet Oxygen in Photosensitization

Journal of Environmental Pathology, Toxicology and Oncology, 2006
Oxygen is a ubiquitous element and a vitally important substance for life on the Earth, and especially for human life. Living organisms need oxygen for most, if not all, of their cellular functions. On the other hand, oxygen can produce metabolites that are toxic and potentially lethal to the same cells.

Genotoxicity of singlet oxygen

Chemico-Biological Interactions, 1991
Singlet oxygen, 1O2 (1 delta g), fulfills essential prerequisites for a genotoxic substance, like hydroxyl radicals and other oxygen radicals: it can react efficiently with DNA and it can be generated inside cells, e.g. by photosensitization and enzymatic oxidation.
