  Synthesis and Study of a Series of 3-Arylcoumarins as Potent and Selective Monoamine Oxidase B Inhibitors

  摘要：

  New series of 6-substituted-3-arylcoumarins displaying several alkyl, hydroxyl, halogen, and alkoxy groups in the two benzene rings have been designed, synthesized, and evaluated in vitro as human monoamine cuddase A and B (hMAO-A and hMAO-B) inhibitors. Most of the studied compounds showed a high affinity and selectivity to the hMAO-B isoenzyme, with IC50 values on nanomolar and picomolar range. Ten of the 22 described compounds displayed higher MAO-B inhibitory activity and selectivity than selegiline. Coumarin 7 is the most active compound of this series, being 64 times more active than selegiline and also showing the highest hMAO-B specificity. In addition, docking experiments were carried out on hMAO-A and h-MAO-B structures. This study provided new information about the enzyme inhibitor interaction and the potential therapeutic application of this 3-arylcoumarin scaffold.

  AP2238 was the first compound published to bind both anionic sites of the human acetylcholinesterase, allowing the simultaneous inhibition of the catalytic and the amyloid-beta pro-aggregating activities of AChE. Here we attempted to derive a comprehensive structure-activity relationship picture for this molecule, affording 28 derivatives for which AChE and BChE inhibitory activities were evaluated. Selected compounds were also tested for their ability to prevent the AChE-induced A beta-aggregation. Moreover, docking simulations and molecular orbital calculations were performed.
