Formation and Functions of Protein Sulfenic Acids
Current Protocols in Toxicology, 2003AbstractProtein sulfenic acids are generated as reversibly oxidized cysteinyl residues formed upon reaction of thiols with peroxides, nitric oxide, peroxynitrite, and other reactive oxygen or nitrogen species. They can be stabilized within the protein environment, irreversibly oxidized to sulfinic and sulfonic acids by additional oxidant, condensed ...

Reactivity of Sulfenic Acid in Human Serum Albumin
Biochemistry, 2007Sulfenic acid is formed upon oxidation of thiols and is a central intermediate in the redox modulation of an increasing number of proteins. Methods for quantifying or even detecting sulfenic acid are scarce. Herein, the reagent 7-chloro-4-nitrobenz-2-oxa-1,3-diazole was determined not to be suitable as a chromophoric probe for sulfenic acid in human ...

Protein sulfenic acid formation
2011Protein sulfenic acid formation has long been regarded as unwanted damage caused by reactive oxygen species (ROS). However, over the past 10 years, accumulating evidence has shown that the reversible oxidation of cysteine thiol groups to sulfenic acid functions as a redox-based signal transduction mechanism.

Synthesis and Characterization of Thiophenetriptycene-8-sulfenic Acid
Phosphorus, Sulfur, and Silicon and the Related Elements, 1997Abstract: Reaction of the trilithium salt, prepared by treatment of 1,1,1-tris(2-bromo-5-methyl-3-thienyl)ethane, with O,O′-diethyl thiocarbonate gave thiophenetriptycene-8-thiol in 42% yield. The thiol was not oxidized with m-chloroperoxybenzoic acid (MCPBA).

Unsymmetrical Target Disulfides from Transient Sulfenic Acids
Phosphorus, Sulfur, and Silicon and the Related Elements, 2011Abstract In accordance with our research interests devoted to the development of synthetic procedures involving sulfenic acids as intermediates, their condensation with various thiols has been exploited as an easy and versatile methodology to obtain unsymmetrical disulfides. Even if this reaction is well known, to the best of our knowledge it has never

The chemistry of sulfenic acids
Sulfenic acids (RSOH) were generated by flash vacuum pyrolysis (FVP) of sulfoxides (RS(O)R) and their relative reactivities were determined by reaction with alkenes and alkynes. Although thiosulfinates (RS(O)SR) are formed in almost all reactions that are believed to involve sulfenic acid intermediates, the ratio of thiosulfinate to trapped adduct can ...openaire +1 more source
