title: [Antiradical and antioxidant properties of nonsteroidal anti-inflammatory agents--derivatives of pyridinecarboxylic acid].
abstract: A number of pyridincarboxylic acid derivatives PV-1-4, 7 and emoxypine preparation antioxidative activity in yolk lipoprotein suspension was studied by a method of Fe(2+)-initiated biochemiluminescence. Lipid peroxidation in suspension was effectively inhibited by the studied compounds in various concentration ranges. PV 1, 3, 4, 7 inhibited lipid peroxidation at the concentrations 100-fold, then those of PV 2 and emoxypine. Antiradical activity of the studied compounds was demonstrated by their forming a complex with the stable diphenylpickrylhydrazyl radical. The effect of these compounds as antioxidants is discussed.
