General description
2-Hydroxyethyldisulfide (HEDS) is an organosulfur compound that belongs to the class ofdialkyl disulfides and has a disulfide bond -S-S- between two hydroxyethylgroups. In material science, HEDS is used as a precursor to form self-assembledmonolayers (SAMs) on gold surfaces for applications such as corrosionprotection, lubrication, and sensors. In addition, 2-hydroxyethyl disulfide isalso used as a reducing agent in organic synthesis and as a crosslinking agentin the production of rubber compounds.
Application
2-Hydroxyethyl disulfide can be used as:
- A chain extender in the preparation of waterborne self-healing polyurethane, which is used in leather coating.
- As a precursor in the synthesis of multifunctional initiator, which is used in the preparation of star polystyrenes by atom transfer radical polymerization of styrene.
- A starting material to prepare a disulfide-based branching agent. This branching agent is used to synthesize highly branched poly(2-hydroxypropyl methacrylate).

African trypanosomes encode three monothiol glutaredoxins (1-C-Grx1 to 3). 1-C-Grx1 has a putative CAYS active site and Cys181 as single additional cysteine. The recombinant protein forms non-covalent homodimers. As observed for other monothiol glutaredoxins, Trypanosoma brucei 1-C-Grx1 was not active

We investigated the effect of protein- and non protein-thiol oxidation on DNA double-strand-break (DSB) rejoining after irradiation and its relevance in the survival of CHO cells. We used mutant cells null for glucose 6 phosphate dehydrogenase (G6PD) activity since reducing

Redox-sensitive yellow fluorescent protein (rxYFP) contains a dithiol disulfide pair that is thermodynamically suitable for monitoring intracellular glutathione redox potential. Glutaredoxin 1 (Grx1p) from yeast is known to catalyze the redox equilibrium between rxYFP and glutathione, and here, we have
