  • Title: Reactions of isolated persulfides provide insights into the interplay between H2S and persulfide reactivity.
    Author: Bailey TS, Pluth MD.
    Journal: Free Radic Biol Med; 2015 Dec; 89():662-7. PubMed ID: 26454077.
    Abstract:
    Hydrogen sulfide is ubiquitous in biological systems and exerts function over a wide range of important physiological processes. Complementing free H2S, the reductant-labile sulfur pool plays significant roles in the translocation and action of sulfide, however the chemistry of reductant-labile sulfide sources has not been studied systematically. Using a combination of NMR and UV-Vis spectroscopy, we investigated the spectroscopic properties and reactivity of three isolated organic persulfides and report a simple model for persulfide reactivity, including their roles as nucleophiles, electrophiles, and sulfide donors.
