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.

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.

The level of sulfane sulfur in the fungus Aspergillus nidulans wild type and mutant strains

Amino Acids, 2008
The interdependence of the sulfane sulfur metabolism and sulfur amino acid metabolism was studied in the fungus Aspergillus nidulans wild type strain and in mutants impaired in genes encoding enzymes involved in the synthesis of cysteine (a precursor of sulfane sulfur) or in regulatory genes of the sulfur metabolite repression system. It was found that

Effects of aspirin on the levels of hydrogen sulfide and sulfane sulfur in mouse tissues

Pharmacological Reports, 2010
This study was designed to investigate the effect of aspirin (ASA) on anaerobic cysteine metabolism, which yields sulfane sulfur-containing compounds and hydrogen sulfide (H(2)S), in mouse liver and brain. In order to solve this problem, we determined the levels of sulfane sulfur and H(2)S, and the activities of cystathionase, the enzyme directly ...

Access to Bis(imidazopyridine)sulfanes by Employing Cysteine as a Greener Sulfur Source

The Journal of Organic Chemistry
An efficient and environmentally friendly protocol has been developed for synthesizing bis(imidazopyridine)sulfanes, employing cysteine as a sulfur source. This method demonstrates a broad substrate scope, accommodating diverse electron-donating and electron-withdrawing functional groups on the imidazopyridine core.

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.
