Monoamine oxidase inhibitors (MAOIs) are a class of drugs that inhibit the activity of one or both monoamine oxidase enzymes: monoamine oxidase A (MAO-A) and monoamine oxidase B (MAO-B). They are best known as effective antidepressants , especially for treatment-resistant depression and atypical depression . [ 1 ]
Monoamine oxidases (MAO) (EC 1.4.3.4) are a family of enzymes that catalyze the oxidation of monoamines, employing oxygen to clip off their amine group. [ 1 ] [ 2 ] They are found bound to the outer membrane of mitochondria in most cell types of the body.
Monoamine oxidase A, also known as MAO-A, is an enzyme (E.C. 1.4.3.4) that in humans is encoded by the MAOA gene. [ 5 ] [ 6 ] This gene is one of two neighboring gene family members that encode mitochondrial enzymes which catalyze the oxidative deamination of amines , such as dopamine , norepinephrine , and serotonin .
Although it has been estimated that a single 300 mg dose of moclobemide inhibits 80% of monoamine oxidase-A (MAO-A) and 20-30% of MAO-B, [100] studies evaluating brain occupancy of MAO-A enzymes have shown dosages of 600 mg to only inhibit 74% of MAO-A enzymes [101] and dosages in the 900–1200 mg range to inhibit slightly less MAO-A than ...
2-NAP is a potent monoamine oxidase inhibitor (MAOI), specifically of monoamine oxidase A (MAO-A) (IC 50 Tooltip half-maximal effective concentration = 420 nM). [8] [3] 1-NAP is an MAOI as well, also of MAO-A (IC 50 = 5,630 nM), but was about 13-fold less potent than 2-NAP. [3] Neither 2-NAP or 1-NAP inhibited monoamine oxidase B (MAO-B) (IC 50 ...
Tranylcypromine, sold under the brand name Parnate among others, [1] is a monoamine oxidase inhibitor (MAOI). [4] [7] More specifically, tranylcypromine acts as nonselective and irreversible inhibitor of the enzyme monoamine oxidase (MAO).
5-MT is metabolized by deamination by monoamine oxidase (MAO), specifically monoamine oxidase A (MAO-A) and to a much lesser extent by monoamine oxidase B (MAO-B). [ 12 ] [ 13 ] [ 14 ] [ 36 ] Brain levels of 5-MT following central administration of 5-MT in rats were potentiated by 20-fold by the MAO-A inhibitor clorgyline and by 5.5-fold by the ...
5-MeO-AMT is a weak monoamine oxidase A (MAO-A) inhibitor, with an IC 50 of 31,000 nM. [19] [14] For comparison, the IC 50 of AMT for MAO-A inhibition was 380 nM (~82-fold more potent than 5-MeO-AMT) [19] [14] and the IC 50 values of amphetamine (and its enantiomers) for MAO-A inhibition have been reported to be 11,000 to 70,000 nM.
