Hydrogen Sulfide Releasing Agents
Abstract
Hydrogen sulfide (H2S) has demonstrated several essential critical care benefits when delivered properly in low doses. The current state of the art delivery systems rely on gaseous delivery of H2S to patients. WSU researchers have developed chemical agents that controllably decompose to release H2S and demonstrated their efficacy in biological...

Sulfur dioxide releasing agents
Abstract Sulfur dioxide has long been considered a toxic environmental pollutant and byproduct of industrial processing. But, more recently it has become evident that sulfur dioxide may also have a regulatory role in mammalian pulmonary systems. Researchers at WSU have discovered novel pharmaceutically relevant compounds that take advantage of this...

Fluorescent probes for the detection of hydrogen polysulfides
AbstractEndogenous hydrogen polysulfides have recently been recognized as important regulators in sulfur-related redox biology. H2Sn can activate tumor suppressors, ion channels, and transcription factors with higher potency than H2Sn. But, a major hurdle in this field is the lack of reliable and convenient methods of H2Sn detection. Researchers at...

Hydrogen Sulfide Detection
Abstract
Hydrogen sulfide (H2S) has been known as a toxic pollutant for years. However, H2S, has been recently recognized as an important signaling molecule of the cardiovascular system, the inflammatory system and the nervous system. H2S is now known as the third endogenous gaseotransmitter, alongside nitric oxide (NO) and carbon monoxide. There...
