Membrane‐Permeable Nucleoside T‐1106 Diphosphate and Triphosphate Analogues as Antiviral Pronucleotides

Chemistry – A European Journal, EarlyView.
Favipiravir (T‐705) and the non‐fluorinated counterpart (T‐1106) are antiviral agents that inhibit the RNA‐dependent RNA polymerase (RdRp) of various RNA viruses. The antiviral efficacy of nucleoside analogues is strongly dependent on their intracellular activation by cellular kinases to produce their corresponding triphosphate metabolites (T‐705‐RTP ...

Ligand‐Level Chemical Activation: Coordination with Benefits

European Journal of Inorganic Chemistry, EarlyView.
While often perceived as a liability, ligand‐based reactivity in carefully designed settings becomes a powerful synthetic tool. The key to streamlined processes overriding classical ionic reactivity is the selective electron redistribution induced by metal coordination. This enables storage of electrons and protons or incorporation of functional groups

Characterization of Cantaloupe, Grape, Pumpkin, and Tomato Seed Oils From Xinjiang: Oxidative Stability, Volatile‐Compound Analysis, and Sensory Evaluation

Food Chemistry International, EarlyView.
This study compares oxidative stability, fatty acid profiles, volatile compounds, and sensory attributes of four Xinjiang seed oils. Distinct aldehyde‐driven aroma patterns and compositional differences were revealed, providing a scientific basis for quality evaluation and valorization of underutilized plant seed oils in food applications.

Spirobifluorene fusion in multiple resonance frameworks enables efficient pure‐red OLEDs with narrowband emission and suppressed efficiency roll‐off

FlexMat, EarlyView.
An orthogonal spirobifluorene‐fusion strategy is introduced for B/N/O‐alternated MR frameworks, enabling improved kRISC (5.46 × 103 s−1), high ΦPL (97%), and narrow‐band pure‐red emission. Vacuum‐evaporated OLEDs incorporating this emitter achieve an EQEmax >40% (FWHM = 36 nm) and exhibit exceptionally low efficiency roll‐off at high luminance ...

Micellar Suzuki–Miyaura Reaction With Xylose Acetal Cosolvents: A Life Cycle Assessment Approach

Helvetica Chimica Acta, EarlyView.
Biomass‐derived solvents (xylose acetals DFX and DPX, and Solvinol) were evaluated for micellar Suzuki–Miyaura reactions in water. High efficiency at low loadings, combined with simplified solvent removal—especially for DFX—reduced solvent waste and environmental impact.
