Sub‐Second Ratiometric Fluorescence Imaging of Histamine Dynamics in Living Cells via a Supramolecular Probe

Advanced Science, EarlyView.
A tailored tripartite supramolecular ratiometric probe, engineered by modulating the fluorogenic guest's cationic locus, enables ultrafast histamine monitoring in living cells. Utilizing a competitive displacement mechanism, this system achieves a sub‐second response time with high selectivity.

Differentiation of three pairs of aconite alkaloid isomers from Aconitum nagarum var. lasiandrum by electrospray ionization tandem mass spectrometry [PDF]

, 2006
Three pairs of isomers of aconite alkaloids from Aconitum nagarum var. lasiandrum have been investigated by electrospray ionization mass spectrometry (ESI-MS) and tandem mass spectrometry (MS/MS) employing ion-trap and quadrupole time-of-flight mass ...

A Fluorogenic Cysteine‐Tetrapeptide Tagging Strategy for Nonperturbative Protein Labeling and Protein–Ligand Interaction Tracking

Advanced Science, EarlyView.
A compact Phe‐Cys‐Pro‐Phe (FCPF) tag and an environment‐sensitive SBD‐Cl‐derived probe form a sequence‐selective fluorogenic pair for wash‐free live‐cell protein imaging. This minimally perturbing chemistry allows flexible insertion at termini or loops, produces strong fluorescence upon local microenvironment confinement, supports FRET‐assisted ...

Astrocyte‐Associated ABCA1/APOE Responses Accompany Hippocampal Lipid Remodeling and Ectopic Neuronal Accumulation During Epileptogenesis

Advanced Science, EarlyView.
During kainic acid‐induced epileptogenesis, astrocyte‐associated ATP‐binding cassette transporter A1 (ABCA1) and apolipoprotein E (APOE) responses accompany ectopic neurons and exploratory lipid alterations. In separate cohorts, bexarotene pretreatment and treatment on days 14–21 are associated with fewer ectopic hilar neurons and lower chronic seizure

An Oral Antiviral Combination Against Severe COVID‐19 Enabled by the Synergistic Mechanisms of Action of Auranofin and Remdesivir

Advanced Science, EarlyView.
FDA‐approved anti‐inflammatory drug Auranofin inhibits SARS‐CoV‐2 replication by inhibiting viral Main protease activity and Spike processing required for viral entry. It shows strong synergy with nucleoside analogue Remdesivir, due to non‐overlapping mechanisms.

Gut Microbiota‐Derived Indole‐3‐Acetaldehyde Contributes to the Disease‐Alleviating Effects of Kurarinone in Experimental Autoimmune Encephalomyelitis

Advanced Science, EarlyView.
Kurarinone ameliorates EAE via the gut microbiota‐indole‐3‐acetaldehyde‐AhR axis. Kurarinone reshapes gut microbiota and increases Akkermansia muciniphila, which promotes intestinal indole‐3‐acetaldehyde production. Indole‐3‐acetaldehyde crosses the intestinal barrier, activates AhR in CD4+ T cells, upregulates SOCS1/3, inhibits JAK2 and STAT3/4 ...

Gold Clusters With Open‐Shell Ligands: Superatom Mediated Magnetic Interaction

Angewandte Chemie, EarlyView.
Open‐shell verdazyl radicals were covalently integrated with atomically precise Ir‐doped Au12 (Ir@Au12) superatoms. The resulting radical–superatom hybrids exhibit photoinduced electron transfer, spin delocalization onto the metal‐cluster core, and weak ferromagnetic communication between radicals mediated by the superatomic electronic structure ...

Cross‐Organ Multi‐Omics Profiling of Systemic Alterations in 5xFAD Mice and Changes Associated with Huanglian Jiedu Decoction Treatment

Advanced Science, EarlyView.
Cross‐organ multi‐omics reveals coordinated inflammatory and metabolic disturbances in 5xFAD mice. Huanglian Jiedu Decoction improves cognition and alleviates brain and liver abnormalities. Complementary hepatocyte–microglia conditioned‐medium experiments suggest PPAR‐γ involvement in treatment‐associated changes in microglial inflammation, providing ...

Proton‐Induced Perthionitrite‐Mediated Zinc Thiolate Persulfidation

Angewandte Chemie, EarlyView.
A thiolate‐supported zinc thionitrite complex reacts with S8 to insert sulfur at both Zn–S bonds. Although SNO− persulfidation to SSNO− is facile, thiolate persulfidation is less favored in comparison. These thermodynamic differences between S–S‐containing moieties are also observed for free perthiolate and SSNO− anions.
