Synthesis and antioxidative activity of metalloporphyrins bearing 2,6-di-tert-butylphenol pendants

Electrochemical Antioxidative Activity Assay of Metalloporphyrins Bearing 2,6-Di-tert-butylphenol Groups Based on DPPH-test

“…CH 3 CN was purified and dried by a known procedure. [6] The concentration of the compounds was 1 mM. For the reaction of these porphyrins with DPPH the concentration ratio was 1:1 (C 0 = 0.1 mM) by measuring CVA curves in certain intervals of time (10 s, 30 s, 1, 3, 5 and 10 min) during 1 h. The compounds under investigation were obtained by procedures described in our previous work.…”

Metal-Based Antioxidants - Potential Therapeutic Candidates for Prevention the Oxidative Stress - Related Carcinogenesis: Mini-Review

“…The in vivo study has been performed for the most active compounds using fish (Asipenser gueldenstaedti B.) and Wistar rats [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42].…”

The First Tetra(meso-аryl)porphyrin with Isobornyl Substituents

“…In this respect the combination of alkyl phenol units with porphyrin macrocycle is rather promising. [1][2][3][4][5] Introduction of several sterically hindered phenol fragments to the periphery of the porphyrin macrocycle can lead to increased antioxidant activity, due to inhibition activity of phenolic moieties in respect to free radicals, and ability of the porphyrin itself to interact with free radicals and oxygen. [6][7] It is known that isobornylphenols possess membrane-protecting properties [8] and can be used as bio-and technical antioxidants.…”
