Synthesis, Antitumor Activity Evaluation and Mechanistic Study of Novel Bis‐Heterocyclic Chalcones Against Liver Cancer

Journal of Clinical Laboratory Analysis, Volume 40, Issue 5, March 2026.
Western blotting was performed to analyze the expression of Caspase 3 and Cleaved‐Caspase 3 in Huh1 cells following different treatments, which supports the finding that bis‐heterocyclic chalcones 3d and 3f can inhibit the activity of hepatocellular carcinoma cells by inducing apoptosis.

Design, Synthesis, and Evaluation of Bis‐Chalcones and Bis‐Flavones as Selective COX‐2 Inhibitors

Chemical Biology &Drug Design, Volume 107, Issue 3, March 2026.
Novel bis‐chalcones were successfully synthesized and demonstrated COX‐2 selective inhibition and the ability to inhibit PGE2 production in whole human blood. Notably, a monomeric chalcone with a similar substitution pattern exhibited even greater activity, providing valuable insights to guide the future design and optimization of flavonoid‐based COX‐2
