chalcones with an electron rich group or sterically large groups such as naphthyl on the carbonyl side tend to activate PPARγ. The absence of any strict structural or electronic requirements suggests that the flexibility of the PPARγ ligand binding pocket may allow binding of diverse chalcones with some preference for a slightly larger electron-rich group on the carbonyl side. We predict that further structure-activity

against five cancer cell lines. Such hybrid derivatives demonstrated significantly increased anti-tumor activity compared with the corresponding amino chalcones. The most promising lead molecules were 1k, 1m and 2j, which had the highest activity toward the five cell lines. Flow cytometry with K562 cells showed that the most active compounds resulted in a large proportion of the cells entering in the apoptotic

A novel approach was developed for the preparation of 4,6-disubstituted-1,2-dihydro-2-oxo-3-pyridinecarboxylic ester in moderate to good yields. This route involves a reaction sequence of Michael addition, transformation to ene-lactam, and aromatization, featuring easily available material, variable substituents, and good functional compatibility.
Numerous studies have shown that chalcones are promising scaffolds for the development of new monoamineoxidase‐B (MAO‐B) inhibitors. As a continuation of our ongoing research into the development of reversible human MAO‐B (hMAO‐B) inhibitors, two series of twenty chalcones containing electron‐donating and electron‐withdrawing substituents were synthesized. All compounds were found to be competitive
