Antioxidant properties of 5,10,15,20-tetrakis(4-hydroxypenyl)porphyrine based on electrochemical and biological researches
The evaluation of antioxidant activity of porphyrin was carried out on the mutual reaction of 5,10,15,20-tetrakis(4-hydroxyphenyl)porphyrin with a free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH). A cyclic voltammetry method was used to research the interaction of porphyrin and DPPH. The results of the electrochemical experiment served as a basis for testing antioxidant qualities of porphyrin on living creatures – chickens of the “Moscow-black” breed. During the duration of the research, no disturbance of physiological condition of the chickens was noticed, as well as any considerable change of body mass or causes of death. The data on blood’s antioxidant activity lets us evaluate the organism’s ability to defend itself from toxic influences of various oxygen-containing compounds. As data shows, the dilution Twin-80 with porphyrin does not lower the blood condition. During the experiment the following was noted: hydroxyl-containing porphyrin with concentrations of 10-4 mole/l lowers the amount of malondialdehyde and increases the amount of ceruloplasmin in blood, which leads to lowering the activity of oxidizing processes in a living organism, and also empowers the protein synthesizing function of the liver.
