Reactive Sulfur Species:  Aqueous Chemistry of Sulfenyl Thiocyanates

Journal of the American Chemical Society, 2004
Sulfenyl thiocyanate (RSSCN) derivatives of penicillamine (PENSCN) and glutathione (GSSCN) have been synthesized in situ at pH = 0 from equilibrium mixtures that consists of hypothiocyanous acid (HOSCN), thiocyanogen ((SCN)2), and trithiocyanate ((SCN)3-). The electrophilic thiocyanating agent N-thiocyanatosuccinimide (NTS) also reacts with PEN and GSH

Strategies for the Design of Donors and Precursors of Reactive Sulfur Species

Chemistry – A European Journal, 2018
AbstractReactive sulfur species (RSS) play regulatory roles in biological systems. Many RSS are highly reactive and transient molecules, making their study difficult. RSS donors or precursors, which are used to specifically produce or deliver RSS, are useful research tools, as well as possible therapeutic agents.

Imaging of Intracellular Reactive Nitrogen Species and Reactive Sulfur Species

2020
This chapter summarizes representative small-molecule fluorescent probes for reactive nitrogen species and reactive sulfur species in living cells. The design and response mechanisms of the probes are described in detail. Probes that have not been applied in living cell analysis are not included.

Reactive Sulfur Species: An Emerging Concept in Oxidative Stress

Biological Chemistry, 2002
The ingredients of oxidative stress include a variety of reactive species such as reactive oxygen and reactive nitrogen species (ROS, RNS). While sulfur is usually considered as part of cellular antioxidant systems there is mounting evidence that reactive sulfur species (RSS) with stressor properties similar to the ones found in ROS are formed under ...

Redox Regulation of Xenobiotics by Reactive Sulfur and Supersulfide Species

Antioxidants & Redox Signaling
Significance: Routine exposure to xenobiotics is unavoidable during our lifetimes. Certain xenobiotics are hazardous to human health, and are metabolized in the body to render them less toxic. During this process, several detoxification enzymes cooperatively metabolize xenobiotics.

On the effect of a high reactive sulfur species on sulfur reduction in gasoline

2004
Varying solutions are available for reducing the amount of sulfur contained in gasoline from fluid catalytic cracking units (FCCUs). However, the use of selective catalysts or additives can be the easiest to implement and potentially represent the most cost effective solution.

Activity-Based Fluorescent Probes for Reactive Sulfur Species

Accounts of Chemical Research
ConspectusReactive sulfur species (RSS), such as hydrogen sulfide (H2S), hydrogen per/polysulfide (H2Sn, n > 1), hydropersulfides (RSSH), and polysulfides (RSnR, n > 2), are believed to play regulatory roles in redox biology. However, their exact mechanisms of action still need to be clarified.

Effect of highly reactive sulfur species on sulfur reduction in cracking gasoline

Applied Catalysis B: Environmental, 2003
Abstract Stringent regulations for engine fuels have stimulated R&D work for reducing sulfur in cracked naphtha in the recent years. In order to progress in this issue information on the effect of the chemistry of sulfur compounds under cracking conditions is needed.

Reactive sulfur species (RSS): persulfides, polysulfides, potential, and problems

Current Opinion in Chemical Biology, 2019
Sulfur is a crucial element in biology due to its unique properties and wide range of accessible oxidation states. This reactivity gives rise to the generation of reactive sulfur species (RSS), which have emerged as a diverse class of small molecules and functional groups with important roles in chemical biology and bioinorganic chemistry.
