Tetrahydroharmol is a bioactive beta-carboline harmala alkaloid. [1] It acts as a reversible inhibitor of monoamine oxidase A. [2]
Harmala alkaloids are considered Schedule 9 prohibited substances under the Poisons Standard (October 2015). [3] 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.

Ayahuasca is a South American psychoactive and entheogenic brewed drink traditionally used both socially and as ceremonial spiritual medicine among the indigenous peoples of the Amazon basin, and more recently in Western society. The tea causes altered states of consciousness, including visual hallucinations and altered perceptions of reality.
N,N-Dimethyltryptamine is a substituted tryptamine that occurs in many plants and animals, including human beings, and which is both a derivative and a structural analog of tryptamine. It is used as a recreational psychedelic drug and prepared by various cultures for ritual purposes as an entheogen.
α-Methyltryptamine is a psychedelic, stimulant, and entactogen drug of the tryptamine class. It was originally developed as an antidepressant by workers at Upjohn in the 1960s, and was used briefly as an antidepressant in Russia under the trade name Indopan before being discontinued.
Methcathinone is a monoamine alkaloid and psychoactive stimulant, a substituted cathinone. It is used as a recreational drug due to its potent stimulant and euphoric effects and is considered to be addictive, with both physical and psychological withdrawal occurring if its use is discontinued after prolonged or high-dosage administration. It is usually snorted, but can be smoked, injected, or taken orally.
Banisteriopsis caapi, also known as ayahuasca, caapi or yagé (yage), is a South American liana of the family Malpighiaceae. It is one half of ayahuasca, a decoction with a long history of its entheogenic use and its status as a "plant teacher" among the Indigenous peoples of the Amazon rainforest.
β-Carboline (9H-pyrido[3,4-b]indole) represents the basic chemical structure for 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 derivatives have recently been shown to have neuroprotective, cognitive enhancing and anti-cancer properties.
para-Methoxyamphetamine (PMA), also known as 4-methoxyamphetamine (4-MA), is a designer drug of the amphetamine class with serotonergic effects. Unlike other similar drugs of this family, PMA does not produce stimulant, euphoriant, or entactogen effects, and behaves more like an antidepressant in comparison, though it does have some psychedelic properties.
Several alkaloids that function as monoamine oxidase inhibitors (MAOIs) are found in the seeds of Peganum harmala, as well as tobacco leaves including harmine, harmaline, and harmalol, which are members of a group of substances with a similar chemical structure collectively known as harmala alkaloids. These alkaloids are of interest for their use in Amazonian shamanism, where they are derived from other plants. The harmala alkaloid harmine, once known as telepathine and banisterine, is a naturally occurring beta-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 both a reversible inhibitor of monoamine oxidase A (RIMAs). They can stimulate the central nervous system by inhibiting the metabolism of monoamine compounds such as serotonin and norepinephrine.
DET, also known under its chemical name N,N-diethyltryptamine and as T-9, is a psychedelic drug closely related to DMT and 4-HO-DET. However, despite its structural similarity to DMT, its activity is induced by an oral dose of around 50–100 mg, without the aid of MAO inhibitors, and the effects last for about 2–4 hours.
Harmine is a beta-carboline and a harmala alkaloid. It occurs in a number of different plants, most notably the Syrian rue and Banisteriopsis caapi. Harmine reversibly inhibits monoamine oxidase A (MAO-A), an enzyme which breaks down monoamines, making it a Reversible inhibitor of monoamine oxidase A (RIMA). Harmine does not inhibit MAO-B. Harmine is also known as banisterin, banisterine, telopathin, telepathine, leucoharmine and yagin, yageine.
Harmaline is a fluorescent indole alkaloid from the group of harmala alkaloids and beta-carbolines. It is the partly hydrogenated form of harmine.
Tetrahydroharmine (THH) is a fluorescent indole alkaloid that occurs in the tropical liana species Banisteriopsis caapi.
Harmalol is a bioactive beta-carboline and a member of the harmala alkaloids.
Indole alkaloids are a class of alkaloids containing a structural moiety of indole; many indole alkaloids also include isoprene groups and are thus called terpene indole or secologanin tryptamine alkaloids. Containing more than 4100 known different compounds, it is one of the largest classes of alkaloids. Many of them possess significant physiological activity and some of them are used in medicine. The amino acid tryptophan is the biochemical precursor of indole alkaloids.
Tryptoline, also known as tetrahydro-β-carboline and tetrahydronorharmane, is a natural organic derivative of beta-carboline. It is an alkaloid chemically related to tryptamines. Derivatives of tryptoline have a variety of pharmacological properties and are known collectively as tryptolines.
6-MeO-THH, or 6-methoxy-1,2,3,4-tetrahydroharman, is a β-carboline derivative and a structural isomer of tetrahydroharmine (7-MeO-THH). 6-MeO-THH is mentioned in Alexander Shulgin's book TiHKAL, stating that 6-MeO-THH is very similar to the other carbolines. Limited testing suggests that it possesses mild psychoactive effects at 1.5 mg/kg and is said to be about one-third as potent as 6-methoxyharmalan. It has been isolated from certain plants of the Virola family.
Pinoline is a methoxylated tryptoline (5-methoxytryptoline) long claimed to be produced in the pineal gland during the metabolism of melatonin, however its pineal occurrence remains controversial. Its IUPAC name is 6-methoxy-1,2,3,4-tetrahydro-β-carboline, usually abbreviated as 6-MeO-THBC, and its more common name is a combination of "pineal beta-carboline". The biological activity of this molecule is of interest as a potential free radical scavenger, also known as an antioxidant, and as a monoamine oxidase A inhibitor.
Harmane (harman) is a heterocyclic amine found in a variety of foods including coffee, sauces, and cooked meat. It is also present in tobacco smoke.
9-Methyl-β-carboline (9-Me-BC) is a heterocyclic amine of the β-carboline family, and a research chemical.
