Description générale

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).

HEDS (2-hydroxyethyl disulfide) and structurally related compounds were found to affect lymphocyte proliferation and functions in vitro. HEDS, and ADA 202-718 (ethylene-2-2'-bis(dithio)bis(ethanol], were shown to stimulate the proliferation of murine spleen cells. The growth of populations of murine T-cells (thymocytes)

Despite the large number of papers dealing with bacterial proteomes, very few include information about proteins with alkaline pI's, because of the limits inherent in 2-DE technology. Nonetheless, analyses of in silico proteomes of many prokaryotes show a bimodal distribution

Incubation of horse liver aldehyde dehydrogenase (aldehyde:NAD oxidoreductase, EC 1.2.1.3) with 2-hydroxyethyl disulfide formed mixed-disulfides between protein sulfhydryl groups and beta-mercaptoethanol. Reduction of aldehyde dehydrogenase activity may be associated with formation of one, or at most two, mixed-disulfides per dehydrogenase

Two novel monothiol glutaredoxins from yeast (ScGrx6 and ScGrx7) were identified and analyzed in vitro. Both proteins are highly suited to study structure-function relationships of glutaredoxin subclasses because they differ from all monothiol glutaredoxins investigated so far and share features
