Novel Applications of Lead Acetate and Flow Cytometry Methods for Detection of Sulfur-Containing Molecules

open access: yesMethods and Protocols, 2019
Hydrogen sulfide (H2S) is the most recently established gaseous vasodilator, enzymatically produced from cysteine metabolism, involved in a number of pathophysiological processes.

Therapeutic Efficacy of the Supersulfide Donor NAC‐S2 in Influenza Virus Pneumonia via Suppression of Excessive Inflammatory Responses

open access: yesMicrobiology and Immunology, Volume 70, Issue 3, Page 148-159, March 2026.
ABSTRACT Influenza pneumonia is characterized by excessive inflammatory responses that contribute to severe lung injury and mortality. Supersulfides, endogenously produced cysteine‐derived persulfides and polysulfides, exert potent antioxidant, anti‐ferroptotic, and anti‐inflammatory activities; however, their therapeutic potential after disease onset ...

Structural Basis for the Oxidation of Protein-bound Sulfur by the Sulfur Cycle Molybdohemo-Enzyme Sulfane Dehydrogenase SoxCD [PDF]

open access: yesJournal of Biological Chemistry, 2011
The sulfur cycle enzyme sulfane dehydrogenase SoxCD is an essential component of the sulfur oxidation (Sox) enzyme system of Paracoccus pantotrophus. SoxCD catalyzes a six-electron oxidation reaction within the Sox cycle. SoxCD is an α(2)β(2) heterotetrameric complex of the molybdenum cofactor-containing SoxC protein and the diheme c-type cytochrome ...

Is Development of High-Grade Gliomas Sulfur-Dependent?

open access: yesMolecules, 2014
We characterized γ-cystathionase, rhodanese and 3-mercaptopyruvate sulfurtransferase activities in various regions of human brain (the cortex, thalamus, hypothalamus, hippocampus, cerebellum and subcortical nuclei) and human gliomas with II to IV grade ...

N‐(Heptafluoroisopropylthio)saccharin as a Practical Reagent for Electrophilic –SCF(CF3)2 Installation

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 3, 3 February 2026.
A bench‐stable saccharin electrophilic reagent enables the direct installation of the heptafluoroisopropylthio group onto diverse (hetero)arenes and amines under mild conditions. The method forms CSRF and NSRF bonds in a single step and allows subsequent oxidation to sulfonamides.

Intermediates in the Sox sulfur oxidation pathway are bound to a sulfane conjugate of the carrier protein SoxYZ. [PDF]

open access: yesPLoS ONE, 2017
The Sox pathway found in many sulfur bacteria oxidizes thiosulfate to sulfate. Pathway intermediates are covalently bound to a cysteine residue in the carrier protein SoxYZ.

A selective and sensitive method for quantification of endogenous polysulfide production in biological samples

open access: yesRedox Biology, 2018
Hydrogen sulfide (H2S) is a gasotransmitter that regulates cellular homeostasis and impacts on multiple physiological and pathophysiological processes. However, it exerts many of its biological actions indirectly via the formation of H2S-derived sulfane ...

Supersulfide biology and translational medicine for disease control

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 1, Page 115-130, January 2026.
Abstract For decades, the major focus of redox biology has been oxygen, the most abundant element on Earth. Molecular oxygen functions as the final electron acceptor in the mitochondrial respiratory chain, contributing to energy production in aerobic organisms. In addition, oxygen‐derived reactive oxygen species including hydrogen peroxide and nitrogen

Thioether Synthesis via the Nickel‐Catalyzed Electrochemical Cross Electrophile Coupling of Aryl/Alkyl Disulfides and Aryl/Alkyl Halides

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 22, November 28, 2025.
A nickel catalyzed electrochemical cross‐electrophile coupling approach for the base‐free synthesis of (un)symmetric (hetero)aryl and alkyl sulfides from organic halides and disulfides is described. The reaction is broadly applicable and tolerates water and air atmosphere. A formal cross‐electrophile coupling approach enables the base‐free synthesis of
