Design, Synthesis, and Evaluation of New Polyhydroxylated Bis‐Chalcones as Potential COX‐2 Selective Inhibitors

ChemMedChem, Volume 21, Issue 8, 28 April 2026.
Novel polyhydroxylated bis‐chalcones were successfully synthesized and demonstrated COX‐2 selective inhibition. The most potent and selective inhibitor exhibited a mixed‐type inhibition mechanism with COX‐2. Its additional bulk preferentially blocked the access to the active pocket of COX‐1 rather than COX‐2. Selective inhibition of COX‐2 is considered

Excimer Formation in Aqueous Solutions of Hosts and Application in Synthesis

ChemPhotoChem, Volume 10, Issue 4, April 2026.
This review explores how host‐mediated excimer formation in water, facilitated by supramolecular confinement enhances photochemical synthesis. By improving solubility, local concentrations, and orientational control, these systems can boost efficiency and selectivity in reactions like photocycloadditions and photodimerizations.
