α-(4-Pyridyl N-oxide)-N-tert-butylnitrone was used as spin trapping agent to detect:
the formation of hydroxyl radical adducts during decomposition of hydrogen peroxide in the presence of nickel (II) oligopeptides[1]
hydroxyl radicals[2] and selenide radical anions[3]
Spin trap reagent used to measure ethanol oxidation to 1-hydroxyethyl radical (HER) which can bind to protein. Has also been used in studies of DNA methylation, iron-mediated polyunsaturated fatty acid peroxidation, and free-radical formation by Alzheimer β-amyloid peptide. The formation of hydroxyl radical in chondrocytes and cartilage has been detected using POBN.

ESR studies using spin traps, 5,5-dimethylpyrroline-N-oxide and alpha-(4-pyridyl 1-oxide)-N-tert-butylnitrone, revealed that hydroxyl radical adducts are produced by the decomposition of hydrogen peroxide in the presence of nickel(II) oligopeptides. Order of catalytic activities of nickel(II) oligopeptides used in the production of
The mitochondrial electron transport chain (mETC) and F1Fo-ATP synthase are of central importance for energy and metabolism in eukaryotic cells. The Apicomplexa, important pathogens of humans causing diseases such as toxoplasmosis and malaria, depend on their mETC in every known
