As previously
stated, the reversibilities of lead compound inhibitions of MAO-A
and MAO-B were assessed after preincubation for 30 min at ∼2
× IC50.37 (link) Reference inhibitors
such as toloxatone (a reversible MAO-A inhibitor), clorgyline (an
irreversible MAO-A inhibitor), lazabemide (a reversible MAO-B inhibitor),
and pargyline (an irreversible MAO-B inhibitor) were also preincubated
at a concentration of ∼2 × IC50 for comparison
with the compounds. Reversibility patterns were identified by comparing
the behaviors of dialyzed (AD) and undialyzed (AU) samples.
