  • C–H functionalization is a key reaction in organic synthesis. Now a selenoxide reagent has been developed for the formation of arylselenonium salts via C–H functionalization of DNA conjugates with high selectivity. The arylselenonium salts participate in various transformations to forge new C–C and C–X bonds.

  • Cysteine bioconjugation is an important method to modify biomolecules, but synthetic efforts to diversify reactive warheads and the low reactivity of introducible linchpins often impede application in biological laboratories. Now, a thianthrenium-based reagent permits site-selective installation of episulfonium on biomacromolecules, enabling one-step addition of bioorthogonal nucleophiles and further applications in quantitative proteomics and cross-linking.

  • Intracellular H2O2 has emerged as a central player in signalling and stress acclimation, but how specificity is achieved remains elusive. Cytosolic peroxiredoxins play a decisive role as they sense H2O2 and transmit the oxidation signal through the formation of disulfide bridges, leading to stomatal closure that reduces pathogen entry.
