Esterase-Sensitive Glutathione Persulfide Donor
Organic Letters, 2018An 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 inhibitory effect toward glyceraldehyde 3-phosphate dehydrogenase (GAPDH).

Persulfides, at the crossroads between hydrogen sulfide and thiols
Essays in Biochemistry, 2020Abstract Persulfides (RSSH/RSS−) can be formed in protein and non-protein thiols (RSH) through several different pathways, some of which are dependent on hydrogen sulfide (H2S/HS−). In addition to their roles in biosynthetic processes, persulfides are possible transducers of physiological effects of H2S through the modification of ...

Thiiranes: Intelligent Molecules for S-Persulfidation
Journal of the American Chemical SocietyThis study presents a global strategy for the transsulfuration of intracellular thiols (RSH) to persulfides (RSSH). Thiiranes comprising fluorenyl/diphenyl and malonate ester moieties directly convert intercellular RSH to low-molecular-weight RSSH in cells.

Generation of reactive oxygen species by a persulfide (BnSSH)
Bioorganic & Medicinal Chemistry Letters, 2005Hydropersulfides (RS(x)SH) have been implicated as important intermediates in the cell-killing action of the anticancer natural products leinamycin and varacin. It has been suggested that persulfides can mediate the conversion of molecular oxygen to reactive oxygen species (O2*-, H2O2, and HO*).

Transfer of persulfide sulfur from thiocystine to rhodanese
Biochimica Et Biophysica Acta - Biomembranes, 1979THiocystine (bis-[2-amino-2-carboxyethyl]trisulfide) is a natural substrate for rhodanese (thiosulfate:cyanide sulfurtransferase, EC 2.8.1.1). Analogs of thiocystine were prepared by eliminating the carboxyl or amino group or by lengthening the carbon chain.

Structural Properties and Torsional Dynamics of Peroxides and Persulfides
2009For the study of molecules containing O—O and S—S bonds, an analysis on the effect of level of theory and basis sets on electronic properties and geometrical parameters for H2O2 and H2S2 was done. Substitutions of one or both hydrogens in these molecules either by halogen atoms or alkyl groups were investigated for properties like geometries, dipole ...

Journal of the American Chemical Society
Persulfides (RSSH) have been proposed as key players in biochemical transformations that often involve iron, including iron-sulfur cluster assembly, H2S regulation, post translational modifications, and mitochondrial sulfur oxidation. An example of the latter is found in the O2-mediated oxidation of glutathione persulfide to sulfite dianion (SO32 ...
