Five compounds exhibit high inhibition and selectivity against MAO−B, with IC50 values in the low micromolar range. In addition, three compounds better antioxidants than butylated hydroxytoluene (BHT). Important features for MAO−B inhibitory activity were observed by docking analysis: H-bonding interaction between Tyr435, Tyr398 and FAD co-factor.acceso restringidoLead compoundDocking (animal)Monoamine oxidase BDesign, Synthesis and Docking Calculations of Prenylated Chalcones as Selective Monoamine Oxidase B Inhibitors with Antioxidant Activityjournal-article
