A series of para-ring-substituted (E)- and (Z)-1-aryl-2-fluorocyclopropylamines were examined as inhibitors of recombinant human liver monoamine oxidase A (MAO A) and B (MAO B). Unlike the parent 1-phenylcyclopropylamine, which is a selective inhibitor of MAO B, both (E)- and (Z)-diastereomers of derivatives having fluorine at the 2-position of the cyclopropane ring were potent and selective irreversible
