Kinetics of radical oxidation of 4-mercapto-2-nitrobenzoic acid was investigated in the presence of hydrogen peroxide and iron(II) sulfate, i.e. SL hydroxyl radicals generating system. Initial velocities of radical reaction were established by numerization of the course of kinetic dependences. The value of initial reaction velocity was used as a criterion for evaluation of efficacy of ethylened...
The mechanism of suicidal inactivation of lactoperoxidase (LPO) by mercaptomethylimidazole (MMI) has been studied. Analogue studies indicate a specific requirement for the thiol group of MMI for inactivation of LPO in the presence of H2O2. MMI is oxidized via one-electron transfer by LPO compound II as demonstrated by a spectral shift from 430 to 412 nm through an isosbestic point at 421 nm. A ...
The formal C1'-oxidation product, 2-deoxyribonolactone, is formed as a result of DNA damage induced via a variety of agents, including gamma-radiolysis and the enediyne antitumor antibiotics. This alkaline labile lesion may also be an intermediate during DNA damage induced by copper-phenanthroline. Oligo-nucleotides containing this lesion at a defined site were formed via aerobic photolysis of ...
Gold(I) Thiolates, (Benzylthiolato)gold(I) Complexes, Gold(I) Mercaptocarboxylates, Polynu clear Gold(I) Complexes In a search for air-stable and water-soluble mercapto compounds of gold with a high gold content, benzylthiol, a-mercapto-acetic acid, /3-mercapto-propionic acid, and thiosalicylic acid were converted into aurated sulfonium salts by treatment with reagents of the type [(R^PjAufiO*...
A diffusive gradients in thin films (DGT) technique for selectively measuring As(III) utilizes commercially available 3-mercaptopropyl-functionalized silica gel. Deployment of the new technique alongside the Metsorb-DGT for total inorganic arsenic allows the calculation of As(III) directly and As(V) by difference. Uptake of As(III) by mercapto-silica was quantitative and elution with a mixture ...
Mercaptobenzothiazole (MBT) compounds are well known contact allergens. To detect rubber allergic patients we use both MBT (2% in petrolatum) and a mercapto-mix with 4 constituents of 0.5% each in our standard series. In this article the EECDRG presents data of in total 32,475 consecutive tested patients attending the respective contact dermatitis clinics from 11 centres in Europe to determine ...
