The reactivity of [Formula: see text] and (CH3)2ĊOH radicals with hypoxanthine was studied under comparable γ-irradiation conditions. A difference in regioselectivity of attack by the electrophilic [Formula: see text] radical and the nucleophilic (CH3)2ĊOH radical is observed, the latter leading in 70% yield to a C-8 substituted product. The rate constants of the addition of the radical to hypoxanthine were determined by pulse radiolysis to be k = 1.4 × 108 M−1 s−1 in acid medium, and in neutral medium k = 7 × 105 M−1 s−1. The much more reactive [Formula: see text] radical leads essentially to

Les expériences ont été réalisées à pH 3,0, à une température de 25,0 (± 0,2) °C, en milieu perchlorate, en présence et en absence d'oxygène dissous. L'étude comparative a confirmé que les vitesses de décomposition de H2O2 et d'oxydation de l'atrazine sont beaucoup plus lentes en présence de Cu(II) qu'en présence de Fe(III) et l'addition de Cu(II) augmente l'efficacité du système Fe(III)/H2

Thirty-eight phenolic compounds (including 31 flavonoids) were examined for their DPPH radical-scavenging activities, and structure-activity relationships were evaluated. Specifically, the presence of an Ortho-dihydroxyl structure in phenolics is largely responsible for their excellent antiradical activity. 3-Hydroxyl was also essential to generate a high radical-scavenging activity.

Abstract The role of oxygen radicals in lysis of K562 target cells by human natural killer (NK) cells was determined by addition of scavengers of these free radicals. Lysis was greatly reduced under hypoxic conditions. Superoxide dismutase and cytochrome c, scavengers of superoxide anions, and catalase and scavengers of hypochlorite had no effect on lysis. Of 15 hydroxyl radical scavengers tested, 13 inhibited lysis. These were not toxic, because cell morphology and spontaneous chromium release were not affected and preculture with scavengers was not inhibitory. These scavengers differed widel

Abstract The influence of dihydroneopterin on tyrosine hydroxylase activity in PC 12 cells was investigated under normoxic and hyperoxic conditions, and with or without iron ions in the incubation medium. Low dihydroneopterin concentrations as well as hyperoxia increase tyrosine hydroxylase activity. Due to a too vigorous radical formation, high dihydroneopterin concentrations lead to a decrease of tyrosine hydroxylation in normoxic state and even more strongly in hyperoxic state. Similar depression of tyrosine hydroxylase activity was seen after addition of iron ions, which can form hydroxyl

Resumo:
The HOCO radical is crucially important in combustion chemistry as the intermediate in the reaction between hydroxyl radicals and carbon monoxide. Studies of the temperature dependence of the rate constant for this reaction implied the existence of the radical intermediate1 but only very recently was HOCO detected in the gas phase2,3. Both the infrared spectrum3, which is due to the perturbed C=O stretching fundamental (v2), and the observed rotational spectrum2 consist only of a-dipole transitions. Such transitions obey the selection rule ΔKa = 0 in this near prolate top rotor and as such con
