Journal ArticleDOI
On the antioxidant mechanism of curcumin: classical methods are needed to determine antioxidant mechanism and activity.
TL;DR: Curcumin is a classical phenolic chain-breaking antioxidant, donating H atoms from the phenolic groups not the CH(2) group as has been suggested.
Journal ArticleDOI
Mechanism of antioxidant reaction of vitamin E. Charge transfer and tunneling effect in proton-transfer reaction
TL;DR: In this article, a kinetic and ab initio study of the antioxidant action (intermolecular proton transfer) of vitamin E derivatives has been carried out, where the second-order rate constants for the reaction of tocopherols (TocH's) with variously substituted phenoxyl radicals (PhO.'s) in ethanol were measured with a stopped-flow spectrophotometer.
Journal ArticleDOI
Kinetic and ab initio study of the prooxidant effect of vitamin E. Hydrogen abstraction from fatty acid esters and egg yolk lecithin
TL;DR: In this paper, a kinetic and ab initio study of the prooxidant effect of vitamin E derivatives has been carried out and the second-order rate constant for the hydrogen abstraction dramatically increases as the number of π-electron systems activating the hydrogen (C=C double bonds) increases from zero to two.
Journal ArticleDOI
Investigation of triplet states of 2-(2-hydroxyphenyl)benzothiazole and 2-(2-hydroxyphenyl)benzoxazole by transient absorption spectroscopy and ab initio calculations
TL;DR: In this paper, transient absorption spectroscopy and ab initio calculations of the 3π,π * ) states of 2-(2'-hydroxyphenyl)benzothiazole (HBT) and 2-hydroxymhenyl)-benzoxazoles (HBO) were investigated.
Journal ArticleDOI
Magnetic Properties of 1,5-Dimethylverdazyl Radical Crystals. Ferromagnetism in 3-(4-Chlorophenyl)-1,5-dimethyl-6-thioxoverdazyl Radical Crystal
TL;DR: In this article, the authors measured the heat capacity and ac susceptibility of organic radical crystals, 3-(4-chlorophenyl)-1,5-dimethyl-6-thioxoverdazyl (p-CDTV), and found that p-BDTV behaves as a quasi-one-dimensional Heisenberg ferromagnet with the intrachain exchange interaction of 2J/kB = +12.0 ± 0.2 K.
