[Protection of beta-adrenoreceptors of the rat brain during emotional-pain stress by oxidants of the steric hindrance class of phenols]. / Zashchita beta-adrenoretseptorov mozga krys pri émotsional'no-bolevom stresse antioksidantom klassa prostranstvenno-zatrudnennykh fenolov.

Adaptogenic properties of a new antioxidant-isoquinoline derivative of hindered phenol class under pain-emotional stress have been investigated. This new antioxidant was shown to have stress-protective effects, i.e. it stabilizes cerebral beta-adrenoreceptors, inhibits lipid peroxidation and stimulates anti-radical defense systems in the brain and serum, as well as normalizes vegetative functions in rats.

[The mechanisms of the antioxidant action of shielded phenols in biological membranes. The effects of 4-methyl-2,6-di-tert-butylphenol (ionol) and its derivatives]. / Mekhanizmy antioksidantnogo deistviia ékranirovannykh fenolov v biologicheskikh membranakh. Effekty 4-metil-2,6-ditretbutil-fenola (ionola) i ego proizvodnykh.

According to Bulgarian-Soviet program "Biostab" we studied characteristics of different phenol compounds (ionol derivatives). The aim of the present study is to determine antiradical and antioxidant activity of a number of ionol derivatives in pure chemical systems and in different membrane fractions of a natural origin.
