Some simple, highly reactive, inorganic chlorine derivatives in aqueous solution. Their formation using pulses of radiation and their role in the mechanism of the Fricke dosimeter
In aqueous solution OH radicals react with chloride ions to form initially ClOH–, the rate constant being 4.3 ± 0.4 × 109 l. mol–1 s–1. The rate constant for the dissociation of ClOH– back to OH… Expand
The reaction between the superoxide anion radical and cytochrome c.
1. The superoxide anion radical (O2-) reacts with ferricytochrome c to form ferrocytochrome c. No intermediate complexes are observable. No reaction could be detected between O2- and ferrocytochrome… Expand
Reactions of the semiquinone free radicals of anti‐tumour agents with oxygen and iron complexes
Antitumor drug Mitomycin C Adriamycin Oxygen Iron complex Pulse radiolysis
One-electron reactions in biochemical systems as studied by pulse radiolysis. IV. Oxidation of dihydronicotinamide-adenine dinucleotide.
1. 1. OH radicals oxidize NADH non-specifically, but weaker one-electron oxidizing agents made by reaction of OH with Br− or other solutes will oxidize NADH stoichiometrically to the NAD.… Expand
The radiation chemistry of some platinum-containing radiosensitizers and related compounds.
Oxidation and reduction of cis- and trans-dichlorodiammine platinum II (cis- and trans-PDD), cis-dichlorobis(1-(2-hydroxyethyl)-2-methyl-5-nitroimidazole-N3)-p latinum II (cis-Flap), and… Expand
Oxidation of ferrous ions by perhydroxyl radicals
Hydroxyl radicals have been found by pulse radiolysis to oxidize hydrated ferrous to ferric ions with a rate constant of (2.3 ± 0.2)× 108 M–1 s–1. The corresponding reaction of OD radicals in D2O… Expand
Pulse-radiolysis study of some unstable complexes of iron
Pulse radiolysis of oxygen-containing solutions of ferrous perchlorate in perchloric acid (l M) enables the formation and disappearances of a ferric hydroperoxide complex, Fe3+HO–2, to be observed.… Expand
Charge transfer between tryptophan and tyrosine in proteins
Abstract With numerous proteins, most of which are not involved in oxidation reduction reactions, azide radicals have been found to react with tryptophan units to give Trp. radicals. The Trp.… Expand
