Reactive sulfane sulfur species such as persulfides (RSSH) and H2S2 are important redox regulators and closely linked to H2S signaling. However, the study of these species is still challenging due to their instability, high reactivity, and the lack of suitable donors to produce them. Herein we report a unique compound, 2H-thiopyran-2-thione sulfine (TTS), which can specifically convert H2S to HSOH, and then to H2S2 in the presence of excess H2S. Meanwhile, the reaction product 2H-thiopyran-2-thione (TT) can be oxidized to reform TTS by biological oxidants. The reaction mechanism of TTS is studied experimentally and computationally. TTS can be conjugated to proteins to achieve specific delivery, and the combination of TTS and H2S leads to highly efficient protein persulfidation. When TTS is applied in conjunction with established H2S donors, the corresponding donors of H2S2 (or its equivalents) are obtained. Cell-based studies reveal that TTS can effectively increase intracellular sulfane sulfur levels and compensate for certain aspects of sulfide:quinone oxidoreductase (SQR) deficiency. These properties make TTS a conceptually new strategy for the design of donors of reactive sulfane sulfur species.

Supersulfides, which are defined as sulfur species with catenated sulfur atoms, are increasingly being investigated in biology. We recently identified pyridoxal phosphate (PLP)-dependent biosynthesis of cysteine persulfide (CysSSH) and related supersulfides by cysteinyl-tRNA synthetase (CARS). Here, we investigated the physiological role of CysSSH in budding yeast (Saccharomyces cerevisiae) by generating a PLP-binding site mutation K109A in CRS1 (the yeast ortholog of CARS), which decreased the synthesis of CysSSH and related supersulfides and also led to reduced chronological aging, effects that were associated with an increased endoplasmic reticulum stress response and impaired mitochondrial bioenergetics. Reduced chronological aging in the K109A mutant could be rescued by using exogenous supersulfide donors. Our findings indicate important roles for CARS in the production and metabolism of supersulfides-to mediate mitochondrial function and to regulate longevity.

Sulfur is essential in the inception of life and crucial for maintaining human health. This mineral is primarily supplied through the intake of proteins and is used for synthesizing various sulfur-containing biomolecules. Recent research has highlighted the biological significance of endogenous supersulfides, which include reactive persulfide species and sulfur catenated residues in thiol and proteins. Ingestion of exogenous sulfur compounds is essential for endogenous supersulfide production. However, the content and composition of supersulfides in foods remain unclear. This study investigated the supersulfide profiles of protein-rich foods, including edible animal meat and beans. Quantification of the supersulfide content revealed that natto, chicken liver, and bean sprouts contained abundant supersulfides. In general, the supersulfide content in beans and their derivatives was higher than that in animal meat. The highest proportion (2.15 %) was detected in natto, a traditional Japanese fermented soybean dish. These results suggest that the abundance of supersulfides, especially in foods like natto and bean sprouts, may contribute to their health-promoting properties. Our findings may have significant biological implications and warrant developing novel dietary intervention for the human health-promoting effects of dietary supersulfides abundantly present in protein-rich foods such as natto and bean sprouts.

SIGNIFICANCE: Persulfides/polysulfides are sulfur-catenated molecular species (i.e., R-Sn-R', n > 2; R-Sn-H, n > 1, with R = cysteine, glutathione, and proteins), such as cysteine persulfide (CysSSH). These species are abundantly formed as endogenous metabolites in mammalian and human cells and tissues. However, the persulfide synthesis mechanism has yet to be thoroughly discussed. RECENT ADVANCES: We used β-(4-hydroxyphenyl)ethyl iodoacetamide and mass spectrometry to develop sulfur metabolomics, a highly precise, quantitative analytical method for sulfur metabolites. CRITICAL ISSUES: With this method, we detected appreciable amounts of different persulfide species in biological specimens from various organisms, from the domains Bacteria, Archaea, and Eukarya. By using our rigorously quantitative approach, we identified cysteinyl-tRNA synthetase (CARS) as a novel persulfide synthase, and we found that the CysSSH synthase activity of CARS is highly conserved from the domains Bacteria to Eukarya. Because persulfide synthesis is found not only with CARS but also with other sulfotransferase enzymes in many organisms, persulfides/polysulfides are expected to contribute as fundamental elements to substantially diverse biological phenomena. In fact, persulfide generation in higher organisms-i.e., plants and animals-demonstrated various physiological functions that are mediated by redox signaling, such as regulation of energy metabolism, infection, inflammation, and cell death including ferroptosis. FUTURE DIRECTIONS: Investigating CARS-dependent persulfide production may clarify various pathways of redox signaling in physiological and pathophysiological conditions and may thereby promote the development of preventive and therapeutic measures for oxidative stress as well as different inflammatory, metabolic, and neurodegenerative diseases.

Recently, the relationship between Helicobacter cinaedi (H. cinaedi) infection and several diseases, including cardiovascular and central nervous system disorders, bone and soft tissue disorders, and infectious abdominal aortic aneurysms (AAAs), has been reported. Moreover, H. cinaedi may be associated with arteriosclerosis. In the present study, we investigated the association between H. cinaedi infection and clinically uninfected AAAs. Genetic detection of H. cinaedi in the abdominal aneurysm wall was attempted in 39 patients with AAA undergoing elective open surgery between June 2019 and June 2020. DNA samples extracted from the arterial wall obtained during surgery were analyzed using nested polymerase chain reaction (PCR). The target gene region was the H. cinaedi-specific cytolethal distending toxin subunit B (cdtB). Nine (23.1%) of 39 patients showed positive bands corresponding to H. cinaedi, and further sequencing analyses demonstrated the presence of H. cinaedi DNAs in their aneurysm walls. In contrast, all the non-aneurysm arterial walls in our patients were negative for H. cinaedi. In conclusion, this is the first report of the detection of H. cinaedi in the walls of a clinically non-infectious AAA.

Maintaining a redox balance by means of precisely controlled systems that regulate production, and elimination, and metabolism of electrophilic substances (electrophiles) is essential for normal cardiovascular function. Electrophilic signaling is mainly regulated by endogenous electrophiles that are generated from reactive oxygen species, nitric oxide, and the derivative reactive species of nitric oxide during stress responses, as well as by exogenous electrophiles including compounds in foods and environmental pollutants. Among electrophiles formed endogenously, 8-nitroguanosine 3’,5’-cyclic monophosphate (8-nitro-cGMP) has unique cell signaling functions, and pathways for its biosynthesis, signaling mechanism, and metabolism in cells have been clarified. Reactive persulfide species such as cysteine persulfides and polysulfides that are endogenously produced in cells are likely to be involved in 8-nitro-cGMP metabolism. These new aspects of redox biology may stimulate innovative and multidisciplinary research in cardiovascular physiology and pathophysiology. In our review, we focus on the redox-dependent regulation of electrophilic signaling via reduction and metabolism of electrophiles by reactive persulfides in cardiac cells, and we include suggestions for a new therapeutic strategy for cardiovascular disease.
