Tetrahydroharmol
Tetrahydroharmol is a bioactive β-carboline and harmala alkaloid. It acts as a reversible inhibitor of monoamine oxidase A. Society and culture Legal status Australia Harmala alkaloids are considered Schedule 9 prohibited substances under the Poisons Standard (October 2015). A Schedule 9 substance is a substance which may be abused or misused, the manufacture, possession, sale or use of which should be prohibited by law except when required for medical or scientific research, or for analytical, teaching or training purposes with approval of Commonwealth and/or State or Territory Health Authorities.

Substituted β-carboline
A substituted β-carboline is a chemical compound featuring a β-carboline moiety (chemistry), moiety with one or more chemical substituent, substitutions. β-Carbolines include more than one hundred alkaloids and synthetic compounds. The effects of these substances depend on their respective substituent. Natural β-carbolines primarily influence brain functions but can also exhibit antioxidant effects. Synthetically designed β-carboline Derivative (chemistry), derivatives have recently been shown to have Neuroprotection, neuroprotective, Neuroenhancement, cognitive enhancing and anti-cancer properties. β-Carbolines are indole alkaloids featuring a fused pyridine and indole ring structure similar to tryptamine, forming a three-ringed system with variable saturation in the third ring. β-Carboline alkaloids naturally occur widely in prokaryotes, plants, animals, certain marine tunicates, and foods like coffee and smoked meats, and are also responsible for the fluorescence of sco ...

Harmala Alkaloid
Harmala alkaloids are several alkaloids that act as monoamine oxidase inhibitors (MAOIs). These alkaloids are found in the seeds of ''Peganum harmala'' (also known as harmal or Syrian rue), as well as ''Banisteriopsis caapi'' (ayahuasca), leaves of tobacco and coffee beans. The alkaloids include harmine, harmaline, harmalol, and their derivatives, which have similar chemical structures, hence the name "harmala alkaloids". These alkaloids are of interest for their use in Amazonian shamanism, where they are derived from other plants. Harmine, once known as telepathine and banisterine, is a naturally occurring substituted β-carboline, β-carboline alkaloid that is structurally related to harmaline, and also found in the vine ''Banisteriopsis caapi''. Tetrahydroharmine is also found in ''B. caapi'' and ''P. harmala''. Dr. Alexander Shulgin has suggested that harmine may be a breakdown product of harmaline. Harmine and harmaline are reversible inhibitors of monoamine oxidase A (RIMA ...

Reversible Inhibitor Of Monoamine Oxidase A
Reversibility can refer to: * Time reversibility, a property of some mathematical or physical processes and systems for which time-reversed dynamics are well defined :* Reversible diffusion, an example of a reversible stochastic process * Reversible process (thermodynamics), a process or cycle such that the net change at each stage in the combined entropy of the system and its surroundings is zero * Reversible reaction, a chemical reaction for which the position of the chemical equilibrium is very sensitive to the imposed physical conditions; so the reaction can be made to run either forwards or in reverse by changing those conditions * Reversible computing, logical reversibility of a computation; a computational step for which a well-defined inverse exists * Reversible error, a legal mistake invalidating a trial * Reversible garment, a garment that can be worn two ways * Piaget's theory of cognitive development Piaget's theory of cognitive development, or his genetic epistemo ...

Standard For The Uniform Scheduling Of Medicines And Poisons
The Standard for the Uniform Scheduling of Medicines and Poisons (SUSMP), also known as the Poisons Standard for short, is an Australian Statutory instrument, legislative instrument produced by the Therapeutic Goods Administration (TGA)., subsection 4A. Before 2010, it was known as the ''Standard for the Uniform Scheduling of Drugs and Poisons'' (''SUSDP'').. The SUSMP classifies drugs and poisons into different Schedules signifying the degree of control recommended to be exercised over their availability to the public.. The Schedules are referred to under States and territories of Australia, State and Territory legislation for regulatory purposes. Although each State and Territory has its own laws, the vast majority of medicines and poisons are classified according to the SUSMP to achieve uniform national regulation. Schedules Schedule 1 Schedule 1 is blank. Schedule 1 does not currently contain any medicines or poisons. Schedule 2: Pharmacy Medicine Schedule 2 (S2) ...

Tetrahydroharmine
Tetrahydroharmine (THH) is a fluorescent indole alkaloid and β-carboline that occurs in the tropical liana species ''Banisteriopsis caapi''. Effects THH has been reported to produce psychoactive effects similar to those of harmaline in humans. It has been reported to be about one-third as potent as harmaline at a dose of 300mg orally. THH is believed to be one of the constituents of ''Banisteriopsis caapi'' responsible for the hallucinogenic effects of the plant. Pharmacology THH, like other harmala alkaloids in ''B. caapi'', namely harmaline and harmine, is a reversible inhibitor of monoamine oxidase A (RIMA), but it also inhibits the reuptake of serotonin. THH contributes to ''B. caapi'''s psychoactivity as a serotonin reuptake inhibitor. In contrast to other β-carbolines, THH shows minimal affinity for the serotonin 5-HT2A receptor (Ki = >10,000nM for racemic THH and ''R''(+)-THH, Ki = 5,890nM for ''S''(–)-THH). Similarly, THH shows negligible affinity for the ...

Monoamine Oxidase Inhibitors
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. Reversible inhibitors of monoamine oxidase A (RIMAs) are a subclass of MAOIs that selectively and reversibly inhibit the MAO-A enzyme. RIMAs are used clinically in the treatment of depression and dysthymia. Due to their reversibility, they are safer in single-drug overdose than the older, irreversible MAOIs, and weaker in increasing the monoamines important in depressive disorder. RIMAs have not gained widespread market share in the United States. Medical uses MAOIs have been found to be effective in the treatment of panic disorder with agoraphob ...
