Harnessing Trace Elements: Novel Radiosensitization Strategies for Enhanced Cancer Radiotherapy

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Radiotherapy (RT) is one of the core methods of comprehensive cancer treatment. Globally, more than 40% of cancer patients rely on radiotherapy to achieve tumor control, cure or palliative relief. However, radiation resistance, immunosuppression and normal tissue injury limit its clinical application.

Crystal Engineering of Reticular Materials for Gas‐ and Liquid‐Phase Hydrocarbon Separation

Advanced Materials, Volume 38, Issue 16, 17 March 2026.
Crystal engineering enables systematic study of structure/function relationships as exemplified by pore engineering of reticular sorbents, including porous coordination networks and covalent organic frameworks. This review assesses such studies applied across the full scope of industrially relevant hydrocarbon separations to provide insight into how ...

Copper‐Catalyzed Markovnikov Hydroboration of Alkenes via Hydrogen Atom Transfer (MHAT)

Advanced Synthesis &Catalysis, Volume 368, Issue 3, 3 February 2026.
The copper‐catalyzed Markovnikov hydroboration of alkenes is disclosed. Remarkably, this methodology operates at mild reaction conditions and delivers high catalytic efficiency (TONs and TOFs up to 2800 and 2600 h‐1, respectively). Furthermore, this approach diverges from previous reports by relying on two subsequent hydrogen‐atom‐transfer processes ...

Design, Synthesis, and Molecular Evaluation of SNAr‐Reactive N‐(6‐Fluoro‐3‐Nitropyridin‐2‐yl)Isoquinolin‐3‐Amines as Covalent USP7 Inhibitors Reveals an Unconventional Binding Mode

Archiv der Pharmazie, Volume 358, Issue 8, August 2025.
The ubiquitin‐specific protease 7 (USP7) catalyzes the removal of ubiquitin and protects substrate proteins from degradation. USP7 causes structural changes upon ubiquitin binding, making it particularly suitable for use in covalent targeting approaches. The development, synthesis, and biophysical screening of a series of mildly electrophilic compounds
