Numerous studies have shown that chalcones are promising scaffolds for the development of new monoamine oxidase‐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
