A novel method for the mechanochemical synthesis of unsymmetrical disulfides using phosphorodithioic acid derivatives. [PDF]
Sci RepIn this study, we report the efficient synthesis of unsymmetrical disulfides using a mechanochemical ball-milling approach. This research successfully yielded alkyl-alkyl, alkyl-aryl, and aryl-aryl unsymmetrical disulfides without any detectable ...

Thiol Isomerases: Enzymatic Mechanisms, Models of Oxidation, and Antagonism by Galloylated Polyphenols. [PDF]
Antioxidants (Basel)Thiol isomerases are a family of enzymes that participate in oxidative protein folding. They contain highly reactive vicinal thiols in a CXXC motif within their catalytic domains to mediate thiol-disulfide switching as part of their reductase, oxidase ...

Synthesis of disulfides and 3-sulfenylchromones from sodium sulfinates catalyzed by TBAI. [PDF]
Beilstein J Org ChemA new synthetic method for disulfides and 3-sulfenylchromones is reported. This innovative approach is based on the tetrabutylammonium iodide (TBAI)/H2SO4 reduction system using sodium sulfinate as key component, thus eliminating the need for thiols and ...

Identification of allosteric disulfides from labile bonds in X-ray structures [PDF]
Royal Society Open Science, 2018 Protein disulfide bonds link pairs of cysteine sulfur atoms and are either structural or functional motifs. The allosteric disulfides control the function of the protein in which they reside when cleaved or formed.
