Thiol-addition reactions and their applications in thiol recognition
Chemical Society Reviews, 2013Because of the biological importance of thiols, the development of probes for thiols has been an active research area in recent years. In this review, we summarize the results of recent exciting reports regarding thiol-addition reactions and their applications in thiol recognition.

EXTRACELLULAR THIOLS AND THIOL/DISULFIDE REDOX IN METABOLISM
Annual Review of Nutrition, 2004▪ Abstract Many proteins present on cell surfaces and located in extracellular fluids contain cysteine and methionine residues that are subject to oxidation. These proteins, which include transporters, receptors, and enzymes, respond to variations in the extracellular thiol/disulfide redox environment.

Low-Molecular-Weight Thiols in Thiol–Disulfide Exchange
Antioxidants & Redox Signaling, 2013Oxidative stress is widely invoked in inflammation, aging, and complex diseases. To avoid unwanted oxidations, the redox environment of cellular compartments needs to be tightly controlled. The complementary action of oxidoreductases and of high concentrations of low-molecular-weight (LMW) nonprotein thiols plays an essential role in maintaining the ...

Chemically Induced Vinylphosphonothiolate Electrophiles for Thiol–Thiol Bioconjugations
Journal of the American Chemical Society, 2020Herein we introduce vinylphosphonothiolates as a new class of cysteine-selective electrophiles for protein labeling and the formation of stable protein-protein conjugates. We developed a straightforward synthetic route to convert nucleophilic thiols into electrophilic, thiol-selective vinylphosphonothiolates: In this protocol, intermediately formed ...

Immune system and thiols: Some peculiarities of thiol exchange
Comparative Immunology, Microbiology and Infectious Diseases, 2010We show that for the system of SH-containing compounds of the organism (cysteine, in particular) there are conditions leading to immunosuppression, which occurs when the level of amino acid cysteine in blood serum increases. The arising "overload" of free sulfhydryl groups inactivates antibodies of the IgM class of any specificity restoring disulphide ...

New Thiols for Photoinitiator‐Free Thiol‐Acrylate Polymerization
Macromolecular Chemistry and Physics, 2013AbstractNew thiols for efficient thiol‐ene polymerization reactions are presented. They do not exhibit any unpleasant odor, are characterized by quite good light‐absorption properties at λ > 300 nm, and generate thiyl radicals upon UV‐light exposure.

ROS, thiols and thiol-regulating systems in male gametogenesis
Biochimica et Biophysica Acta (BBA) - General Subjects, 2015During maturation and storage, spermatozoa generate substantial amounts of reactive oxygen species (ROS) and are thus forced to cope with an increasingly oxidative environment that is both needed and detrimental to their biology. Such a janus-faceted intermediate needs to be tightly controlled and this is done by a wide array of redox enzymes.

Thiol-dependent and non-thiol-dependent stimulations of insulin release
Diabetes, 1984The effects of reduced glutathione (GSH) and diamide (an oxidant of GSH) on insulin release induced by glucose, glyceraldehyde, leucine, tolbutamide, glibenclamide, Ca-ionophore A-23187, isoprenaline, and db-cAMP were studied using isolated rat pancreatic islets.

The Journal of Physical Chemistry C, 2011
Self-assembly of organic thiols is the most common way to introduce functional groups onto gold surfaces. Although the gold–sulfur (Au–S) bond is moderately strong (∼45 kcal/mol), it is also prone to oxidation, which substantially weakens the Au–S interaction. In this work, we describe the creation of more robust molecular assemblies on gold.
