Abstract

A large series of substituted chalcones have been synthesized and tested in vitro for their ability to inhibit human monoamine oxidases A and B (hMAO-A and hMAO-B). While all the compounds showed hMAO-B selective activity in the micro- and nanomolar ranges, the best results were obtained in the presence of chlorine and hydroxyl or methoxyl substituents. To better understand the enzyme-inhibitor interaction and to explain the selectivity of the most active compounds toward hMAO-B, molecular modeling studies were carried out on new, high resolution, hMAO-B crystallographic structures. For the only compound that also showed activity against hMAO-A as well as low selectivity, the molecular modeling study was also performed on the hMAO-A crystallographic structure. The docking technique provided new insight on the inhibition mechanism and the rational drug design of more potent/selective hMAO inhibitors based on the chalcone scaffold.
