A Direct Method to Prepare Zwitterionic Organotrifluoroborates: Ammonium and Sulfonium Derivatives

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 18, 14 May 2026.
Organotrifluoroborates find applications in synthesis, diagnostics, and theranostics. This study outlines a one‐step reaction for producing ammonium and sulfonium trifluoroborate zwitterion derivatives. This method achieves satisfactory yields without the need for expensive reagents.

Novel Applications of Lead Acetate and Flow Cytometry Methods for Detection of Sulfur-Containing Molecules

open access: yesMethods and Protocols, 2019
Hydrogen sulfide (H2S) is the most recently established gaseous vasodilator, enzymatically produced from cysteine metabolism, involved in a number of pathophysiological processes.

Hydroxytyrosol Mitigates Anxiety‐Like Behaviors After a Traumatic Experience in Aged Mice in Parallel With Increased Neurogenesis in the Ventral and Dorsal Dentate Gyrus, and Preservation of Gut Microbiota Composition

open access: yesJournal of Neurochemistry, Volume 170, Issue 5, May 2026.
Hydroxytyrosol (HTyr), a phenolic compound of olive oil, exerts beneficial effects on several age‐related diseases. We previously demonstrated that oral HTyr administration in aging mice enhances hippocampal neurogenesis, known to play a role in memory formation and emotional behaviors. In the present study, we found that HTyr preferentially stimulates

Synthesis of Sulfur Heterocycles by Palladium‐Catalyzed Cyclization

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 14, 15 April 2026.
In spite of the well‐known palladium thiophilicity, sulfur‐containing acyclic substrates may efficiently undergo several different kinds of palladium‐catalyzed cyclization processes leading to highly important sulfur heterocycles in one synthetic step. Advances in this challenging and stimulating field of research are presented in this review.

Is Development of High-Grade Gliomas Sulfur-Dependent?

open access: yesMolecules, 2014
We characterized γ-cystathionase, rhodanese and 3-mercaptopyruvate sulfurtransferase activities in various regions of human brain (the cortex, thalamus, hypothalamus, hippocampus, cerebellum and subcortical nuclei) and human gliomas with II to IV grade ...

Chemical Upcycling of Polyphenylene Sulfide at Room Temperature

open access: yesAdvanced Science, Volume 13, Issue 22, 17 April 2026.
Poly(phenylene sulfide) (PPS) is a semi‐crystalline super engineering plastic with exceptional properties. An iron‐photocatalyzed strategy is reported for chemical upcycling of PPS plastics at room temperature using 1,2‐dichloroethane. The method demonstrates remarkable efficiency across diverse PPS resins and post‐consumer composites, even within ...

Clonal Stabilization Reveals a DAO/3MST‐Expressing MDCK Subpopulation With Robust d‐Cysteine‐Mediated H2S Production

open access: yesThe FASEB Journal, Volume 40, Issue 6, 31 March 2026.
A subpopulation of MDCK (NBL‐2) cells, an epithelial cell line derived from the normal kidney, expresses DAO and 3MST. The DAO/3MST‐expressing cells are progressively eliminated during passaging; however, clonal isolation enables the establishment of sublines that maintain stable H2S production. Clonal cells co‐expressing DAO and 3MST therefore provide

A selective and sensitive method for quantification of endogenous polysulfide production in biological samples

open access: yesRedox Biology, 2018
Hydrogen sulfide (H2S) is a gasotransmitter that regulates cellular homeostasis and impacts on multiple physiological and pathophysiological processes. However, it exerts many of its biological actions indirectly via the formation of H2S-derived sulfane ...

Therapeutic Efficacy of the Supersulfide Donor NAC‐S2 in Influenza Virus Pneumonia via Suppression of Excessive Inflammatory Responses

open access: yesMicrobiology and Immunology, Volume 70, Issue 3, Page 148-159, March 2026.
ABSTRACT Influenza pneumonia is characterized by excessive inflammatory responses that contribute to severe lung injury and mortality. Supersulfides, endogenously produced cysteine‐derived persulfides and polysulfides, exert potent antioxidant, anti‐ferroptotic, and anti‐inflammatory activities; however, their therapeutic potential after disease onset ...
