Esterase-Sensitive Glutathione Persulfide Donor

Organic Letters, 2018
An esterase-sensitive glutathione persulfide (GSSH) donor (BW-GP-401) is described. The release profile was studied by monitoring the formation of lactone and direct trapping of GSSH with 1-fluoro-2,4-dinitrobenzene (DNFB). The donor was examined for its

Zero-valent sulfur is the product of assimilatory sulfite reductase and a substrate of cysteine synthase [PDF]

Applied and Environmental Microbiology
The process of the assimilatory sulfate reduction consists of sulfate reduction to hydrogen sulfide (H2S) and then H2S assimilation for cysteine synthesis.

Cysteine persulfides and polysulfides produced by exchange reactions with H2S protect SH-SY5Y cells from methylglyoxal-induced toxicity through Nrf2 activation

Redox Biology, 2017
Many physiological functions of hydrogen sulfide (H2S) have been reported in mammalian cells over the last 20 years. These physiological effects have been ascertained through in vitro treatment of cells with Na2S or NaHS, both of which are precursors of ...

The Response of Acinetobacter baumannii to Hydrogen Sulfide Reveals Two Independent Persulfide-Sensing Systems and a Connection to Biofilm Regulation

MBio, 2020
Although hydrogen sulfide (H2S) has long been known as a respiratory poison, recent reports in numerous bacterial pathogens reveal that H2S and more downstream oxidized forms of sulfur collectedly termed reactive sulfur species (RSS) function as ...

Unraveling the Mechanism of Cysteine Persulfide Formation Catalyzed by 3-Mercaptopyruvate Sulfurtransferases

ACS Catalysis, 2018
International audienceSulfhydration of reactive cysteines in target proteins is now recognized as a major route by which H2S mediates signal transduction and regulates various cellular processes.

Characterizations of Two Bacterial Persulfide Dioxygenases of the Metallo-β-lactamase Superfamily [PDF]

, 2015
Persulfide dioxygenases (PDOs), also known as sulfur dioxygenases (SDOs), oxidize glutathione persulfide (GSSH) to sulfite and GSH. PDOs belong to the metallo-β-lactamase superfamily and play critical roles in animals, plants, and microorganisms ...

Synthetic Motifs for Understanding Lewis Acid Interactions with Persulfides and Thioselenides. [PDF]

Angew Chem Int Ed Engl
Using isolated dichalcogenides as precursors, we report the synthesis, characterization, and reactivity of Zn persulfide and thioselenide complexes. 77Se NMR shows distinct impacts to electronic structure and reactivity between different thioselenides coordinated to different Lewis acids.
