For many years reactive oxygen and nitrogen species (ROS and RNS) have been
recognized as key messengers in the process of thiol-based redox regulation. Relatively …

The chemical biology of thiols (RSH, eg, cysteine and cysteine‐containing
proteins/peptides) has been a topic of extreme interest for many decades due to their …

Significance: Hydrogen sulfide (H2S) is reported to be an important mediator involved in
numerous physiological processes. H2S and hydropersulfides (RSSH) species are …

Abstract Significance: Hydrogen sulfide (H2S) plays roles in many physiological processes,
including relaxation of vascular smooth muscles, mediation of neurotransmission, inhibition …

Background and Purpose The signalling associated with hydrogen sulfide (H2S) remains to
be established, and recent studies have alluded to the possibility that H2S‐derived species …

Hydrogen sulfide (H2S) has emerged as a signalling molecule capable of regulating several
important physiological functions such as blood pressure, neurotransmission and …

Hydrogen sulfide (H2S/HS–) can be formed in mammalian tissues and exert physiological
effects. It can react with metal centers and oxidized thiol products such as disulfides (RSSR) …

For decades, reactive persulfide species including cysteine persulfide (CysSSH) have been
known to exist endogenously in organisms. However, the physiological significance of …

Significance: Hydropersulfides (RSSH) are ubiquitous in prokaryotes, eukaryotic cells, and
mammalian tissues. The unique chemical properties and prevalent nature of these species …

Hydrogen sulfide (H 2 S) is an endogenously generated and putative signaling/effector
molecule. Despite its numerous reported functions, the chemistry by which it elicits its …
