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.

Oxygenation of Benzyldimethylamine by Singlet Oxygen. Products and Mechanism

Organic Letters, 2004
[reaction: see text] A product study of the reaction of benzyldimethylamine (1) with thermally and photochemically generated 1O2 in MeCN was carried out. Benzaldehyde and N-benzyl-N-methylformamide are the reaction products, oxygenation representing ca. 9% of the overall quenching of 1O2 by 1.

THE SINGLET OXYGEN REACTIVITY OF BILIVERDIN

Photochemistry and Photobiology, 1977
Abstract— In 1, 1, 2‐trichlorotrifluoroethane solution biliverdin physically quenches singlet oxygen at a rate of 8 × l0sM‐1s‐1 and reacts chemically at 6 × 10 5M‐1s‐1 to give a red product. In D, O solution the rate constants are PD dependent and range from 1.5–6 times 1010M‐1s‐1 for quenching and the chemical rate varies from 3–5 × 108 M‐1 s‐1 to ...

Singlet oxygen and biological systems

Chemico-Biological Interactions, 1971
Abstract Singlet oxygen is receiving increasing attention as a reactive species in many chemical and biological systems. It can be generated easily by microwave discharge, chemically or by photosensitized irradiation and also is found to be a common reactive atmospheric pollutant generated by solar radiation.
