A copper-catalyzed arylation of tryptamines for the direct synthesis of aryl pyrroloindolines [PDF]

, 2012
An operationally simple, copper-catalyzed arylation of N-tosyltryptamines provides direct access to C3-aryl pyrroloindolines. A range of electron-donating and electron-withdrawing substituents is tolerated on both the indole backbone and the aryl ...

Crystallographic fragment screening against SARS‐CoV‐2 nonstructural protein 1 using the F2X‐Entry Screen and a newly developed fragment library

Acta Crystallographica Section D, EarlyView.
Two crystallographic fragment screening campaigns against SARS‐CoV‐2 nonstructural protein 1 resulted in the identification of 21 new hits.Severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) continues to threaten global health. This underpins the need for novel therapeutics against this virus.

Plasmonic Hot‐Carrier Redox Enables Proton‐Coupled Electron Transfer at C─H Bonds

Angewandte Chemie, Volume 138, Issue 6, 2 February 2026.
Plasmonic hot carriers provide unprecedented control over coupled electron–proton transfer, enabling visible‐light activation of strong C─H bonds. Using an energy‐filter electrode, we reveal a stepwise electron‐then‐proton pathway and directly tune the underlying driving forces.

Epigenetic mechanisms and therapeutic innovations in chronic pain‐associated neuropsychiatric co‐morbidities

British Journal of Pharmacology, EarlyView.
Abstract Chronic pain, marked by nociceptive sensitization and maladaptive neuroplasticity, affects 30% of the global population with escalating socioeconomic burdens. Epidemiological data show a 2‐3‐fold increase in neuropsychiatric co‐morbidities among individuals with chronic pain, where epigenetic dysregulation serves as a key mechanism linking ...

Molecular basis of antibiotic sensing by the TetR family regulator CecR – a structural perspective

The FEBS Journal, EarlyView.
Escherichia coli CecR, a member of the TetR family regulators, senses selected antibiotics and activates the expression of a putative drug efflux pump. Although present in many pathogenic Enterobacteriales strains, CecR remains poorly characterized. We present the first CecR crystal structure, which reveals a unique tunnel‐like ligand‐binding cavity ...
