Mechanisms of antioxidant action: Auto-synergistic

An auto-synergistic mechanism has been shown to be involved due to the ability of nitrones to destroy hydroperoxides in a stoichiometric reaction and at the same time to scavenge alkoxy radicals formed by homolysis of hydroperoxides.

Mechanisms of antioxidant action: Auto-synergistic

The mechanism of by-product formation in the reaction of a thiol antioxidant, 3,5-di-tertbutyl-4-hydroxybenzyl mercaptan (BHBM), with rubber latices is shown to involve two processes, viz dimerization of the intermediate thiyl radical to give disulphide (BHBDS) and the reaction of the intermediate quinonemethide with water to give the aldehyde and with BHBM to give the monosulphide (BHBMS).

Investigation of lipid peroxidation as probable mechanism

It may be concluded that as much as great attention is directed to scavenging free radicals using antioxidants to prevent drugs toxication, it is also more important to direct strategies on modulating drug toxication via other mechanisms such as increased reactivity via conversion of xenobiotics to electrophiles, nucleophiles and redox-active reactants.

Significance of Antioxidant Potential of Plants and its

In ethanopharmacological and nutraceutical investigations, in vitro antioxidant activity assessment methods are often used to screen and confer antioxidant potential to plants or their phytochemicals and sometimes to understand the probable mechanism of action of plant antioxidants 62. In the case of medicinal plants, these assays are used to confer free radical scavenging activity to plants, which in turn has great importance in understanding the role of plants in minimizing the oxidative ...
