Description générale

Potassium nitrosodisulfonate is an oxidizing reagent that can be used to convert phenols, naphthols, and anilines to quinones, benzylic alcohols to aldehydes or ketones, and amino acids to α-keto acids. It can also be used for the preparation of heterocyclic quinones and oxidative aromatization.

Application

Potassium nitrosodisulfonate can be used as an oxidizing reagent for the oxidation of:

Aromatic amines to their corresponding quinones.
Hydroethidine to 2-hydroxyethidium.
Tyrosine to o-quinones.

Stopped-flow ESR study on the reactivity of vitamin E, vitamin C and its lipophilic derivatives towards Fremy's salt in micellar systems.

Z L Liu et al.

Chemistry and physics of lipids, 56(1), 73-80 (1990-11-01)

The reaction between Fremy's salt and alpha-tocopherol (VE), ascorbic acid (VC) and its lipophilic derivatives ascorbyl-6-caprylate (VC-8), 6-laurate (VC-12) and 6-palmitate (VC-16) were studied by stopped-flow ESR spectroscopy in cetyl trimethylammonium bromide (CTAB) and sodium dodecyl sulfate (SDS) micelles, as

Structure-activity studies of antitumor agents based on pyrrolo[1,2-a]benzimidazoles: new reductive alkylating DNA cleaving agents.

I Islam et al.

Journal of medicinal chemistry, 34(10), 2954-2961 (1991-10-01)

Described herein are structure-activity studies of new antitumor agents based on the pyrrolo[1,2-a]benzimidazole (PBI) ring system. These compounds were designed as new DNA cross-linkers mimicking the mitomycin antitumor agents. Actually, the PBI derivatives were found to have anthracycline-like features: (i)

Reduction of the tyrosyl radical and the iron center in protein R2 of ribonucleotide reductase from mouse, herpes simplex virus and E. coli by p-alkoxyphenols.

S Pötsch et al.

FEBS letters, 374(1), 95-99 (1995-10-23)

The rate of reduction of the tyrosyl radical in the small subunit of ribonucleotide reductase (protein R2) from E. coli, mouse, and herpes simplex virus (HSV-2) by a series of p-alkoxyphenols with different alkyl chains, have been studied by stopped-flow

The interaction of bisulfite and its free radical analog-nitroxyldisulfonate with periodic acid-oxidized lymphocytes and their effect on blastogenesis.

F J Hornicek et al.

Chemico-biological interactions, 55(3), 289-302 (1985-11-01)

Nitroxyldisulfonate [Fremy's salt; (KSO3)2NO.] and bisulfite (NaHSO3) have abolished periodic acid (H5IO6)-induced blastogenesis of human peripheral blood lymphocytes (HPBL), but only inhibited the blastogenic response of H5IO6-oxidized rat and mouse lymphocytes, as determined by the rates of nucleic acids synthesis
