Substituted Tetraphenylporphyrins as Promising Molecular Systems with High Antioxidant Activity

The electrochemical approach to antioxidant activity assay of metal complexes with dipicolylamine ligand, containing 2,6-di-tert-butylphenol groups, based on electrochemical DPPH-test

“…In [39] this method was successfully applied to study of substituted tetraphenyporphyrines antioxidant activity. group in order to regulate the solubility and transport function of complexes [41].…”

Kinetics of Induced Deposition of Films Based on Tetrakis(4-Aminophenyl)Porphyrin

“…Particular features of porphyrin compounds, such as the high thermal and chemical stability of macrocycles, possibility of formation of stable complexes with different metals, possibility of variation of the oxidation state of the central metal atom, outstanding chromophoric properties of the π-conjugated macrocycle system, diverse supramolecular behavior, high biocompatibility etc., make this class of compounds attractive for solution to many applied problems. In particular, high biocompatibility of porphyrins allows considering tetraphenylporphyrins as promising drugs for photodynamic treatment of cancer [6,7] and as possible antioxidant agents [8][9][10][11][12][13]. Development of the methods of formation of polyfunctional porphyrin-based film materials [14] is important for development of catalysts [15], sensors [16], electromagnetic radiation converters [17], electronic devices [18], etc.…”

Decline of Prooxidant Activity of Butyl and Phenyl Derivatives of Tin in the Presence of meso-Tetrakis(3,5-di-tert-butyl-4-hydroxyphenyl)porphyrin

“…[2] Исследуются антиоксидантные свойства мезо-замещенных синтетических тетраарилпорфиринов, которые благодаря легкости синтеза и модификации, устойчивости, особым физико-химическим свойствам, широко применяются в технике [3,4] и медицине. [5] Данные соединения препятствуют окислительному гемолизу эритроцитов, [6] обладают антирадикальной активностью. Так, установлена способность мезо-замещенного порфи-рина с фрагментами 2,6-ди-трет-бутилфенола (R 4 PH 2 ) утилизировать супероксид анион-радикал.…”
