Astatine‐211—Towards In Vivo Stable Astatine‐211 Labeled Radiopharmaceuticals and Their (Pre)Clinical Applications

open access: yesMedicinal Research Reviews, Volume 46, Issue 1, Page 203-237, January 2026.
ABSTRACT Targeted radioligand therapy has emerged as a promising treatment option for eradicating advanced cancer forms. α‐Emitters are considered particularly promising as they can obliterate (micro)‐metastases. The α‐emitter astatine‐211 (211At) has experienced increased interest due to its favorable decay properties.

The role of onium salts in the oxidation of hydrocarbons by O2 catalysed by cationic phase-transfer reagents [PDF]

open access: yes, 2000
Experimental and theoretical evidence is presented that cationic phase-transfer catalysts promote the homolytic decomposition of hydroperoxide initiators into radicals, this being a fundamental step in the catalysis of the oxidation of hydrocarbons by O ...

Methanobactin rapidly facilitates biliary copper excretion in a Wilson disease rat model visualised by 64Cu PET/MRI

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 2, Page 268-279, January 2026.
Background and Purpose Methanobactins are peptides with high copper affinity and potential to treat Wilson disease. We examined how two methanobactins (ARBM101 and MB‐OB3b) affected copper handling in the LPP Atp7b−/− Wilson disease rat model, compared to penicillamine or saline, by 64Cu positron emission tomography/magnetic resonance imaging ...

Sc(III) Complexes of Pyclen Derivative Ligands as Probes for Hypoxia: Synthesis, Chemical Characterization, 44Sc‐Radiolabeling, and Preclinical Assessment

open access: yesChemistry – A European Journal, Volume 31, Issue 72, December 23, 2025.
Hypoxia‐sensitive nitroimidazole‐functionalized pyclen derivatives were successfully synthesized and radiolabeled with 44Sc(III), affording stable and inert scandium complexes. Remarkable Sc(III)‐binding capabilities of the PC2A‐mono(amide) platform enabled excellent radiolabeling performance, with ≥92–99% yields and ≥99% radiochemical purity. MicroPET
