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 ]
Norepinephrine degradation. Monoamine oxidase is shown left in the blue box. [11]Monoamine oxidases catalyze the oxidative deamination of monoamines. In the first part of the reaction, cofactor FAD oxidizes the substrate yielding the corresponding imine which converts the cofactor into its reduced form FADH2.
Monoamine oxidase inhibitors (MAOIs) have a long and prosperous history as medications for major depressive disorder (MDD). But this type of antidepressant has mostly seen its day. 4 FDA-Approved ...
Tisolagiline (INN Tooltip International Nonproprietary Name; developmental code names KDS-2010, SeReMABI) is a potent, highly selective, and reversible monoamine oxidase B (MAO-B) inhibitor which is under development for the treatment of Alzheimer's disease and obesity.

The pharmacology of antidepressants is not entirely clear.. The earliest and probably most widely accepted scientific theory of antidepressant action is the monoamine hypothesis (which can be traced back to the 1950s), which states that depression is due to an imbalance (most often a deficiency) of the monoamine neurotransmitters (namely serotonin, norepinephrine and dopamine).

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 norepinephrine , serotonin and tyramine .
The hydrazine antidepressants are a group of non-selective, irreversible monoamine oxidase inhibitors (MAOIs) which were discovered and initially marketed in the 1950s and 1960s. Most have been withdrawn due to toxicity , namely hepatotoxicity , but a few still remain in clinical use.
