Minaprine (INN, USAN, BAN; brand names Brantur, Cantor) is a monoamine oxidase inhibitor antidepressant drug [2] that was used in France for the treatment of depression until it was withdrawn from the market in 1996 because it caused convulsions. [3]
A study found that it acts as a reversible inhibitor of MAO-A (RIMA) in rats. [4] In a study it has also been found to weakly inhibit acetylcholinesterase in rat brain (striatum) homogenates. [5]
It has demonstrated significant antibiotic activity against M. chelonae and M. abscessus in tests with antibiotic resistant bacteria. [6]
Minaprine is a member of pyridazines, a secondary amine and a member of morpholines. It has a role as an antidepressant, a serotonin uptake inhibitor, a dopamine uptake inhibitor, a cholinergic drug and an antiparkinson drug. [7]
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.
Monoamine oxidases (MAO) are a family of enzymes that catalyze the oxidation of monoamines, employing oxygen to clip off their amine group. They are found bound to the outer membrane of mitochondria in most cell types of the body. The first such enzyme was discovered in 1928 by Mary Bernheim in the liver and was named tyramine oxidase. The MAOs belong to the protein family of flavin-containing amine oxidoreductases.
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.
Isocarboxazid is a non-selective, irreversible monoamine oxidase inhibitor (MAOI) of the hydrazine class used as an antidepressant. Along with phenelzine and tranylcypromine, it is one of only three classical MAOIs still available for clinical use in the treatment of psychiatric disorders in the United States, though it is not as commonly employed in comparison to the others.
Trimipramine, sold under the brand name Surmontil among others, is a tricyclic antidepressant (TCA) which is used to treat depression. It has also been used for its sedative, anxiolytic, and weak antipsychotic effects in the treatment of insomnia, anxiety disorders, and psychosis, respectively. The drug is described as an atypical or "second-generation" TCA because, unlike other TCAs, it seems to be a fairly weak monoamine reuptake inhibitor. Similarly to other TCAs however, trimipramine does have antihistamine, antiserotonergic, antiadrenergic, antidopaminergic, and anticholinergic activities.
Moclobemide, sold under the brand names Amira, Aurorix, Clobemix, Depnil and Manerix among others, is a reversible inhibitor of monoamine oxidase A (RIMA) drug primarily used to treat depression and social anxiety. It is not approved for use in the United States, but is approved in other Western countries such as Canada, the UK and Australia. It is produced by affiliates of the Hoffmann–La Roche pharmaceutical company. Initially, Aurorix was also marketed by Roche in South Africa, but was withdrawn after its patent rights expired and Cipla Medpro's Depnil and Pharma Dynamic's Clorix became available at half the cost.
Iproniazid is a non-selective, irreversible monoamine oxidase inhibitor (MAOI) of the hydrazine class. It is a xenobiotic that was originally designed to treat tuberculosis, but was later most prominently used as an antidepressant drug. However, it was withdrawn from the market because of its hepatotoxicity. The medical use of iproniazid was discontinued in most of the world in the 1960s, but remained in use in France until its discontinuation in 2015.
Dibenzepin, sold under the brand name Noveril among others, is a tricyclic antidepressant (TCA) used widely throughout Europe for the treatment of depression. It has similar efficacy and effects relative to other TCAs like imipramine but with fewer side effects.
Clorgiline (INN), or clorgyline (BAN), is a monoamine oxidase inhibitor (MAOI) structurally related to pargyline which is described as an antidepressant. Specifically, it is an irreversible and selective inhibitor of monoamine oxidase A (MAO-A). Clorgiline was never marketed, but it has found use in scientific research. It has been found to bind with high affinity to the σ1 receptor (Ki = 3.2 nM) and with very high affinity to the I2 imidazoline receptor (Ki = 40 pM).
Butriptyline, sold under the brand name Evadyne among others, is a tricyclic antidepressant (TCA) that has been used in the United Kingdom and several other European countries for the treatment of depression but appears to no longer be marketed. Along with trimipramine, iprindole, and amoxapine, it has been described as an "atypical" or "second-generation" TCA due to its relatively late introduction and atypical pharmacology. It was very little-used compared to other TCAs, with the number of prescriptions dispensed only in the thousands.
Opipramol, sold under the brand name Insidon among others, is an anxiolytic and tricyclic antidepressant that is used throughout Europe. Despite chemically being a tricyclic dibenzazepine (iminostilbene) derivative similar to imipramine, opipramol is not a monoamine reuptake inhibitor like most other tricyclic antidepressants, and instead, uniquely among antidepressants, acts primarily as a SIGMAR1 agonist. It was developed by Schindler and Blattner in 1961.
Iproclozide is an irreversible and selective monoamine oxidase inhibitor (MAOI) of the hydrazine chemical class that was used as an antidepressant, but has since been discontinued. It has been known to cause fulminant hepatitis and there have been at least three reported fatalities due to administration of the drug.
Mycobacteroides abscessus is a species of rapidly growing, multidrug-resistant, nontuberculous mycobacteria (NTM) that is a common soil and water contaminant. Although M. abscessus most commonly causes chronic lung infection and skin and soft tissue infection (SSTI), it can also cause infection in almost all human organs, mostly in patients with suppressed immune systems. Amongst NTM species responsible for disease, infection caused by M. abscessus complex are more difficult to treat due to antimicrobial drug resistance.
Reuptake inhibitors (RIs) are a type of reuptake modulators. It is a drug that inhibits the plasmalemmal transporter-mediated reuptake of a neurotransmitter from the synapse into the pre-synaptic neuron. This leads to an increase in extracellular concentrations of the neurotransmitter and an increase in neurotransmission. Various drugs exert their psychological and physiological effects through reuptake inhibition, including many antidepressants and psychostimulants.
LR-5182 is a stimulant drug which acts as a norepinephrine–dopamine reuptake inhibitor, structurally related to the better known drug fencamfamine. It was developed by the pharmaceutical company Eli Lilly in the 1970s, and researched for potential use as an antidepressant, although never marketed. LR-5182 has two stereoisomers, both of which are active, although one isomer blocks reuptake of only dopamine and noradrenaline, while the other blocks reuptake of serotonin as well.
Bifemelane (INN) (Alnert, Celeport), or bifemelane hydrochloride (JAN), also known as 4-(O-benzylphenoxy)-N-methylbutylamine, is an antidepressant and cerebral activator that is widely used in the treatment of cerebral infarction patients with depressive symptoms in Japan, and in the treatment of senile dementia as well. It also appears to be useful in the treatment of glaucoma. Bifemelane acts as a monoamine oxidase inhibitor (MAOI) of both isoenzymes, with competitive (reversible) inhibition of MAO-A (Ki = 4.20 μM) (making it a reversible inhibitor of monoamine oxidase A (RIMA)) and non-competitive (irreversible) inhibition of MAO-B (Ki = 46.0 μM), and also acts (weakly) as a norepinephrine reuptake inhibitor. The drug has nootropic, neuroprotective, and antidepressant-like effects in animal models, and appears to enhance the cholinergic system in the brain.
Pheniprazine is an irreversible and nonselective monoamine oxidase inhibitor (MAOI) of the hydrazine chemical class that was used as an antidepressant in the 1960s. It was also used in the treatment of angina pectoris and schizophrenia. Pheniprazine has been largely discontinued due to toxicity concerns such as jaundice, amblyopia, and optic neuritis.
Pivhydrazine, also known as pivalylbenzhydrazine and pivazide, is an irreversible and non-selective monoamine oxidase inhibitor (MAOI) of the hydrazine family. It was formerly used as an antidepressant in the 1960s, but has since been discontinued.
Ladostigil (TV-3,326) 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 acts as a reversible acetylcholinesterase and butyrylcholinesterase inhibitor, and an irreversible monoamine oxidase B inhibitor, and combines the mechanisms of action of older drugs like rivastigmine and rasagiline into a single molecule. In addition to its neuroprotective properties, ladostigil enhances the expression of neurotrophic factors like GDNF and BDNF, and may be capable of reversing some of the damage seen in neurodegenerative diseases via the induction of neurogenesis. Ladostigil also has antidepressant effects, and may be useful for treating comorbid depression and anxiety often seen in such diseases as well.
Caroxazone is an antidepressant which was formerly used for the treatment of depression but is now no longer marketed. It acts as a reversible monoamine oxidase inhibitor (RIMA) of both MAO-A and MAO-B subtypes, with five-fold preference for the latter.
