A near-infrared fluorescent probe for sensitive detection and imaging of sulfane sulfur in living cells and &ITin vivo&IT

, 2018
Sulfane sulfur refers to ionized sulfur that is reversibly attached to other sulfur atoms in the form of 6-valence electrons (S-0). Sulfane sulfur possesses stronger nucleophilicity and reducibility than hydrogen sulfide in a series of physiological ...

Molecular and energetic basis of histidine switch dynamics in respiratory complex I

Protein Science, Volume 35, Issue 8, August 2026.
Abstract The respiratory complex I in mitochondria and bacteria drives the two‐electron reduction of quinone to pump protons across the membrane. The molecular basis of this catalytic reaction remains enigmatic despite significant progress in structural characterization of the complex.

Advancing the Resolution of the Sulfur Compound Disproportionation Puzzle in Dissulfuribacter Thermophilus S69ᵀ Through Quantitative Label‐Free Comparative Proteomics

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
To date, only three microorganisms have been functionally characterised for sulfur disproportionation. Our work identifies a fourth example and provides novel proteomic insights into its underlying pathways. These findings advance our understanding of microbial sulfur catabolism and highlight the ecological role of D.

Cars2‐Mediated Cysteine Catabolism Drives Brown Fat Development and Thermogenesis Through Persulfidating EBF2

Advanced Science, Volume 13, Issue 31, 4 June 2026.
We demonstrate that Cars2, a cysteine catabolic enzyme in mouse iBAT, is critical for cold tolerance and brown adipocyte differentiation. Through its CPERS activity, Cars2 produces CysSSH/H2S to induce EBF2 persulfidation, promoting its interaction with PPARγ and BRG1 to enhance thermogenic gene expression.

Thiosulfonate‐Derived BODIPY “Stick and Glue” Strategy for Fluorescent Thiol Labeling

Angewandte Chemie, Volume 138, Issue 6, 2 February 2026.
We present a powerful photochemical strategy for converting disulfide bonds into stable thioether linkages via a [1,2]‐sigmatropic rearrangement. By integrating this reaction into traditional methanethiosulfonate‐based thiol labeling, we enable light‐triggered stabilization of peptide and protein conjugates with enhanced robustness and versatility ...

Sulfane Decreases the Nucleophilic Reactivity of Zinc Thiolates: Implications for Biological Reactive Sulfur Species

, 2022
A zinc dithiolate complex supported by a [N3S2] ligand was studied as a model for zinc-mediated thiolate-disulfide exchange, enabling isolation of a zinc-bound mixed-disulfide intermediate.

Synthesis of (E)‐β‐SF5‐Styrenes via a Heck Reaction of in situ Generated Vinylsulfur Pentafluoride†

Chinese Journal of Chemistry, Volume 44, Issue 11, Page 1823-1827, 1 June 2026.
A Heck cross‐coupling reaction between aryl(hetero)iodides and in situ generated vinylsulfur pentafluoride is reported. This reaction provides β‐SF5‐styrenes in one‐step as a single (E)‐stereoisomer and tolerates a broad range of functional groups. Comprehensive Summary The synthesis of (E)‐(1‐alken‐1‐yl)pentafluoro‐λ6‐sulfanes, a valuable class of ...

Sodium thiosulfate treatment rescues hyperglycaemia‐induced pronephros damage in zebrafish by upregulating nitric oxide signalling

The Journal of Physiology, Volume 604, Issue 11, Page 4247-4260, 1 June 2026.
Abstract figure legend Sodium thiosulfate (STS) rescues the pronephros phenotype of pdx1 morphants through compensatory upregulation of nitric oxide (NO) metabolism. Zebrafish larvae injected with a control morpholino show the typical pronephros structure at 48 h post‐fertilization (hpf) with and without STS treatment.
