Symmetrical Imidazo[1,5‐a]pyridine Dimers as Novel Organic Light Emitters: Bidirectional Synthesis and Photoluminescence Characterization

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 3, January 22, 2026.
Imidazo[1,5‐a]pyridine dimers are synthesized via a bidirectional strategy and characterized by single‐crystal X‐ray diffraction. The key substitution position for tuning optical properties is identified. Photophysical studies, supported by density functional theory calculations, show fluorescence in the 490–580 nm range, with the most planar system ...

The Novel Antitubulin Agent TR-764 Strongly Reduces Tumor Vasculature and Inhibits HIF-1α Activation [PDF]

open access: yes, 2016
Tubulin binding agents (TBAs) are commonly used in cancer therapy as antimitotics. It has been described that TBAs, like combretastatin A-4 (CA-4), present also antivascular activity and among its derivatives we identified TR-764 as a new inhibitor of ...

Recent Synthetic Advances in C–H/N–H Functionalization of 1H‐Pyrazoles: Diverse Strategies Across Variously Substituted Scaffolds

open access: yesThe Chemical Record, Volume 25, Issue 12, December 2025.
Systematic overview of pyrazole functionalization reactions from C‐5 to N−H. It covers different strategies, from traditional cross‐coupling of prefunctionalized pyrazoles to more efficient direct functionalizations. This review briefly and systematically overviews C–H and N–H functionalization reactions of pyrazoles, aimed at creating new CC and C ...
