Using resonance synchronous spectroscopy to characterize the reactivity and electrophilicity of biologically relevant sulfane sulfur

Redox Biology, 2019
Sulfane sulfur is common inside cells, playing both regulatory and antioxidant roles. However, there are unresolved issues about its chemistry and biochemistry.

Sulfur ligated oxoiron(IV) centre in fenton-like reaction: Theoretical postulation and experimental verification

Catalysis Communications, 2022
The intermediate FeIVO in circumneutral Fenton-like reactions is critical in selective oxidations. However, the inferior electron donation of ligands renders the reactivity of oxoiron(IV) cores.

Polysulfide stabilization by tyrosine and hydroxyphenyl-containing derivatives that is important for a reactive sulfur metabolomics analysis

Redox Biology, 2019
The physiological importance of reactive sulfur species (RSS) such as cysteine hydropersulfide (CysSSH) has been increasingly recognized in recent years.

The Inactivation of LPS Biosynthesis Genes in E. coli Cells Leads to Oxidative Stress

Cells, 2022
Impaired lipopolysaccharide biosynthesis in Gram-negative bacteria results in the “deep rough” phenotype, which is characterized by increased sensitivity of cells to various hydrophobic compounds, including antibiotics novobiocin, actinomycin D ...

Adaptation of Candida albicans to Reactive Sulfur Species. [PDF]

Genetics, 2017
Abstract Candida albicans is an opportunistic fungal pathogen that is highly resistant to different oxidative stresses. How reactive sulfur species (RSS) such as sulfite regulate gene expression and the role of the transcription factor Zcf2 and the sulfite exporter Ssu1 in such responses are not known. Here, we show that C.

Geminal-dithiol-based precursors for reactive sulfur species.

Chem Commun (Camb)
The chemistry and reactivity of a free gem-dithiol, 1,3-diphenylpropane-2,2-dithiol, and its derivatives (S-nitrosothiol and dithiirane) are studied. These compounds can release H2S, NO, or induce S-persulfidation.

Reactive oxygen species or reactive sulfur species: why we should consider the latter [PDF]

Journal of Experimental Biology, 2020
ABSTRACT The biological effects of oxidants, especially reactive oxygen species (ROS), include signaling functions (oxidative eustress), initiation of measures to reduce elevated ROS (oxidative stress), and a cascade of pathophysiological events that accompany excessive ROS (oxidative distress).
