MAO inhibition by arylisopropylamines: the effect of oxygen substituents at the β-position
摘要:
Twenty-nine arylisopropylamines, substituted at the beta-position of their side chain by an oxo, hydroxy, or methoxy group, were evaluated in vitro as MAO-A and MAO-B inhibitors. The oxo derivatives ('cathinones') were in general less active as MAO-A inhibitors than the corresponding arylisopropylamines, but exhibited an interesting MAO-13 inhibiting activity, which was absent in the hydroxy, methoxy, and beta-unsubstituted analogues. These results suggest that selective affinity for the two MAO isoforms in this family of compounds is modulated not only by the aryl substitution pattern but also by the side-chain substituents on the aryl-alkylamine scaffold.
