Possible involvement of sulfane sulfur in homocysteine-induced atherosclerosis

Medical Hypotheses, 2001
Homocysteinemia, first identified as a genetic disease in children in the 1960s, is associated with severe widespread atherosclerosis which causes death (in untreated cases) before the age of 10 years. Elevated blood homocysteine is now recognized as a risk factor for heart disease in the general population.

Benzothiazole-Derived Sulfones and Sulfoxides as Reactive Templates for Biothiols and Sulfane Sulfurs

Organic Letters, 2022
In this work we studied the reactions of benzothiazole sulfones and sulfoxides toward reactive sulfur species. The reaction of thiols with benzothiazole sulfones produces sulfinic acids (RSO2H), which can further react with sulfane sulfurs to form thiosulfonic acids (RSO2SH). This was used to design fluorescent sensors for hydrogen polysulfides.

Cysteine-Persulfide Sulfane Sulfur-Ligated Zn Complex of Sulfur-Carrying SufU in the SufCDSUB System for Fe-S Cluster Biosynthesis.

Inorganic Chemistry
SufU, a component of the SufCDSUB Fe-S cluster biosynthetic system, serves as a Zn-dependent sulfur-carrying protein that delivers inorganic sulfur in the form of cysteine persulfide from SufS to SufBCD.

Sensitive Method for Reliable Quantification of Sulfane Sulfur in Biological Samples

Analytical Chemistry, 2019
Sulfane sulfur has been recognized as a common cellular component, participating in regulating enzyme activities and signaling pathways. However, the quantification of total sulfane sulfur in biological samples is still a challenge. Here, we developed a method to address the need.

Visualization of Sulfane Sulfur in Plants with a Near-Infrared Fluorescent Probe

ACS Sensors, 2019
Sulfane sulfur species are an important type of reactive sulfur species. These compounds have unique reactivity to attach reversibly to other sulfur atoms and exhibit regulatory effects in diverse biological systems. Recent studies have suggested that sulfane sulfurs are involved in signal transduction processes of hydrogen sulfide (H2S).

Biological actions of lipoic acid associated with sulfane sulfur metabolism.

Pharmacological reports : PR, 2009
This work aimed to investigate the effect of lipoic acid (LA) on sulfane sulfur (S(*)) level and rhodanese activity in rat tissues. In vitro studies conduced so far have indicated that dihydrolipoic acid serves as an S(*) acceptor in the rhodanese-catalyzed S(*) transfer.
