Detection strategies for superoxide anion: A review

Talanta, 2022
Reactive oxygen species (ROS) play an essential role in regulating various physiological functions of living organisms. Superoxide anion (O2-.), one kind of ROS, is the single-electron reduction product of oxygen molecules, which mainly exists in plants and animals, and is closely related to many inflammatory diseases. In the field of biomedicine, with

The nature of the superoxide radical anion in water

The Journal of Chemical Physics, 2013
Vibrational properties of the superoxide radical anion (O2−•) in liquid water have been experimentally investigated for the first time. The stretching frequency, its shift from the gas-phase to aqueous solution, anharmonicity constant, and the Raman bandwidths provide an insight into the radical-water interactions and the hydration cage. In view of the

Versatile fluorescent probes for visualizing superoxide anion in living cells and in vivo.

Angewandte Chemie, 2020
As metabolites in live cells and in vivo, reactive oxygen species (ROS) are a topic of broad and constant concern. The superoxide anion (O2•-), representing the first ROS produced in organisms, is widely engaged in the regulation of cell functions and is

Flavonoids are scavengers of superoxide anions

Journal of Ethnopharmacology, 1988
Seven flavonoids and three non-flavonoid antioxidants, i.e. butylated hydroxyanisole, chlorpromazine and BW 755 C, were studied as potential scavengers of oxygen free radicals. Superoxide anions were generated enzymatically in a xanthine-xanthine oxidase system and non-enzymatically in a phenazine methosulphate-NADH system, and assayed by reduction of ...

The superoxide anion in lymphocyte transformation

Immunology Letters, 1984
This work suggests that reactive oxygen intermediates can stimulate lymphocytes mitogenically. Incubation of human peripheral blood lymphocytes in solutions of potassium superoxide induced high levels of uptake of tritiated thymidine as did activation of monocyte production of superoxide ions using zymosan-A.
