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. They are also used to treat panic disorder, social anxiety disorder, Parkinson's disease, and several other disorders.
Tranylcypromine, sold under the brand name Parnate among others, is a monoamine oxidase inhibitor (MAOI). More specifically, tranylcypromine acts as nonselective and irreversible inhibitor of the enzyme monoamine oxidase (MAO). It is used as an antidepressant and anxiolytic agent in the clinical treatment of mood and anxiety disorders, respectively. It is also effective in the treatment of ADHD.
Selegiline, also known as L-deprenyl and sold under the brand names Eldepryl, Zelapar, and Emsam among others, is a medication which is used in the treatment of Parkinson's disease and major depressive disorder. It has also been studied for a variety of other indications, but has not been formally approved for any other use. The medication in the form licensed for depression has modest effectiveness for this condition that is similar to that of other antidepressants. Selegiline is provided as a swallowed tablet or capsule or an orally disintegrating tablet (ODT) for Parkinson's disease and as a patch applied to skin for depression.
Deprenyl, also known by its developmental code name E-250 and as N-propargylmethamphetamine, is the racemic mixture of D-deprenyl and L-deprenyl (selegiline). It was discovered in 1961 in Hungary at Chinoin Pharmaceutical Company by Zoltan Ecseri and József Knoll, was patented in 1962, and was first described in the literature in 1964 or 1965.
Tetrabenazine is a drug for the symptomatic treatment of hyperkinetic movement disorders. It is sold under the brand names Nitoman and Xenazine among others. On August 15, 2008, the U.S. Food and Drug Administration approved the use of tetrabenazine to treat chorea associated with Huntington's disease. Although other drugs had been used "off label," tetrabenazine was the first approved treatment for Huntington's disease in the U.S. The compound has been known since the 1950s.
Dopaminergic means "related to dopamine", a common neurotransmitter. Dopaminergic substances or actions increase dopamine-related activity in the brain.
Rasagiline, sold under the brand name Azilect among others, is a medication which is used in the treatment of Parkinson's disease. It is used as a monotherapy to treat symptoms in early Parkinson's disease or as an adjunct therapy in more advanced cases. The drug is taken by mouth.
Pargyline, sold under the brand name Eutonyl among others, is a monoamine oxidase inhibitor (MAOI) medication which has been used to treat hypertension but is no longer marketed. It has also been studied as an antidepressant, but was never licensed for use in the treatment of depression. The drug is taken by mouth.
(–)-Benzofuranylpropylaminopentane is an experimental drug related to selegiline which acts as a monoaminergic activity enhancer (MAE). It is orally active in animals.
1-Phenyl-2-propylaminopentane is an experimental drug related to selegiline which acts as a catecholaminergic activity enhancer (CAE).
Monoamine oxidase B, also known as MAO-B, is an enzyme that in humans is encoded by the MAOB gene.
Levoamphetamine is a stimulant medication which is used in the treatment of certain medical conditions. It was previously marketed by itself under the brand name Cydril, but is now available only in combination with dextroamphetamine in varying ratios under brand names like Adderall and Evekeo. The drug is known to increase wakefulness and concentration in association with decreased appetite and fatigue. Pharmaceuticals that contain levoamphetamine are currently indicated and prescribed for the treatment of attention deficit hyperactivity disorder (ADHD), obesity, and narcolepsy in some countries. Levoamphetamine is taken by mouth.
Carbidopa/levodopa/entacapone, sold under the brand name Stalevo among others, is a dopaminergic fixed-dose combination medication that contains carbidopa, levodopa, and entacapone for the treatment of Parkinson's disease.
Ladostigil is a novel neuroprotective agent being investigated for the treatment of neurodegenerative disorders like Alzheimer's disease, Lewy body disease, and Parkinson's disease. It was developed from structural modification of rasagiline.
Mofegiline (MDL-72,974) is a selective, irreversible inhibitor of monoamine oxidase B (MAO-B) and semicarbazide-sensitive amine oxidase (SSAO) which was under investigation for the treatment of Parkinson's disease and Alzheimer's disease, but was never marketed.
Monoaminergic activity enhancers (MAE), also known as catecholaminergic/serotonergic activity enhancers (CAE/SAE), are a class of compounds that enhance the action potential-evoked release of monoamine neurotransmitters in the nervous system. MAEs are distinct from monoamine releasing agents (MRAs) like amphetamine and fenfluramine in that they do not induce the release of monoamines from synaptic vesicles but rather potentiate only nerve impulse propagation-mediated monoamine release. That is, MAEs increase the amounts of monoamine neurotransmitters released by neurons per electrical impulse.
Desmethylselegiline (DMS), also known as norselegiline or as N-propargyl-L-amphetamine, is an active metabolite of selegiline, a medication used in the treatment of Parkinson's disease and depression.
The pharmacology of selegiline is the study of the pharmacodynamic and pharmacokinetic properties of the antiparkinsonian and antidepressant selegiline (L-deprenyl). Selegiline is available in a few different forms, including oral tablets and capsules, orally disintegrating tablets (ODTs), and transdermal patches. These forms have differing pharmacological properties.
(R)-1-Aminoindan ((R)-1-AI; developmental code name TVP-136 or TV-136), or (R)-1-aminoindane, is the major metabolite of the selective MAO-B inhibitor and antiparkinsonian agent rasagiline ((R)-N-propargyl-1-aminoindan). In contrast to rasagiline, it lacks significant monoamine oxidase inhibition. In addition, unlike selegiline and its amphetamine metabolites, it lacks monoamine reuptake-inhibiting and -releasing activities and associated amphetamine-like psychostimulant effects. However, (R)-1-aminoindan retains neuroprotective effects and certain other activities.
1-Aminoindane (1-AI), also known as 1-aminoindan, 1-indanylamine, or 1-indanamine, is an aminoindane. It is a positional isomer of 2-aminoindane. A variety of notable derivatives of 1- and 2-aminoindane are known. The (R)-enantiomer of 1-aminoindan, (R)-1-aminoindan, is pharmacologically active and is an active metabolite of the antiparkinsonian agent rasagiline.
