Voacangine
Voacangine (12-methoxyibogamine-18-carboxylic acid methyl ester) is an alkaloid found predominantly in the root bark of the '' Voacanga africana'' tree, as well as in other plants such as ''Tabernanthe iboga'', '' Tabernaemontana africana'', '' Trachelospermum jasminoides'', ''Tabernaemontana divaricata'' and '' Ervatamia yunnanensis''. It is an iboga alkaloid which commonly serves as a precursor for the semi-synthesis of ibogaine. It has been demonstrated in animals to have similar anti-addictive properties to ibogaine itself. It also potentiates the effects of barbiturates. Under UV-A and UV-B light its crystals fluoresce blue-green, and it is soluble in ethanol. Pharmacology Pharmacodynamics Voacangine exhibits AChE inhibitory activity. Docking simulation reveals that it has inhibitory effect on VEGF2 kinase and reduces angiogenesis. Like ibogaine, its a potent HERG blocker in vitro. It also acts as antagonist to TRPM8 and TRPV1 receptor but agonist of TRPA1. Pharmacokinetic ...

Ibogaine
Ibogaine is a naturally occurring psychoactive substance found in plants in the family Apocynaceae such as '' Tabernanthe iboga'', '' Voacanga africana'', and '' Tabernaemontana undulata''. It is a psychedelic with dissociative properties. Preliminary research indicates that it may help counter drug addiction. Its use has been associated with serious side effects and death. Between the years 1990 and 2008, a total of 19 fatalities temporally associated with the ingestion of ibogaine were reported, from which six subjects died of acute heart failure or cardiopulmonary arrest. The total number of subjects who have used it without major side effects during this period remains unknown. It is used as an alternative medicine treatment for drug addiction in some countries. Its prohibition in other countries has slowed scientific research. Ibogaine is also used to facilitate psychological introspection and spiritual exploration. Various derivatives of ibogaine designed to lack psyched ...

Ervatamia Yunnanensis
''Tabernaemontana'' is a genus of flowering plants in the family Apocynaceae. It has a pan-tropical distribution, found in Asia, Africa, Australia, North America, South America, and a wide assortment of oceanic islands. These plants are evergreen shrubs and small trees growing to 1–15 m tall. The leaves are opposite, 3–25 cm long, with milky sap; hence it is one of the diverse plant genera commonly called "milkwood". The flowers are fragrant, white, 1–5 cm in diameter. The cultivar '' T. divaricata'' cv. 'Plena', with doubled-petaled flowers, is a popular houseplant. Some members of the genus ''Tabernaemontana'' are used as additives to some versions of the psychedelic drink ayahuasca; the genus is known to contain ibogaine (e.g. in bëcchëte, ''T. undulata''), conolidine (present in minor concentration in ''T. divaricata'') and voacangine ('' T. alba'', '' T. arborea'', '' T. africana''). Because of presence of coronaridine and voacangine in Mexican ''Tabe ...

Alkaloids are a class of basic BASIC (Beginners' All-purpose Symbolic Instruction Code) is a family of general-purpose, high-level programming languages designed for ease of use. The original version was created by John G. Kemeny and Thomas E. Kurtz at Dartmouth College ..., natural product, naturally occurring organic compounds that contain at least one nitrogen atom. This group also includes some related compounds with neutral and even weakly acidic properties. Some synthetic compounds of similar structure may also be termed alkaloids. In addition to carbon, hydrogen and nitrogen, alkaloids may also contain oxygen, sulfur and, more rarely, other elements such as chlorine, bromine, and phosphorus.Chemical Encyclopedia: alkaloids

18-Methoxycoronaridine
18-Methoxycoronaridine (18-MC, or MM-110) is a derivative of ibogaine invented in 1996 by the research team around the pharmacologist Stanley D. Glick from the Albany Medical College and the chemists Upul K. Bandarage and Martin E. Kuehne from the University of Vermont. In animal studies it has proved to be effective at reducing self-administration of morphine, cocaine, methamphetamine, nicotine and sucrose. It has also been shown to produce anorectic effects in obese rats, most likely due to the same actions on the reward system which underlie its anti-addictive effects against drug addiction. 18-MC was in the early stages of human testing by the California-based drug development company Savant HWP before being acquired by MindMed, a Canadian pharmaceutical company newly listed on the NASDAQ in April 2021.

Coronaridine
Coronaridine, also known as 18-carbomethoxyibogamine, is an alkaloid found in ''Tabernanthe iboga'' and related species, including ''Tabernaemontana divaricata'' for which (under the now obsolete synonym ''Ervatamia coronaria'') it was named. Like ibogaine, (''R'')-coronaridine and (''S'')-coronaridine can decrease intake of cocaine and morphine intake in animals and it may have muscle relaxant and hypotensive activity. Chemistry Congeners Coronaridine congers are important in drug discovery and development due to multiple actions on different targets. They have ability to inhibit Cav2.2 channel, modulate and inhibit subunits of nAChr selectively such as α9α10, α3β4 and potentiate GABAA activity. Pharmacology Coronaridine has been reported to bind to an assortment of molecular sites, including: μ-opioid (Ki = 2.0 μM), δ-opioid (Ki = 8.1 μM), and κ-opioid receptors (Ki = 4.3 μM), NMDA receptor (Ki = 6.24 μM) (as an antagonist), and nAChRs (as an antagonist). It h ...

HERG Blocker
hERG (the human '' Ether-à-go-go''-Related Gene) is a gene () that codes for a protein known as Kv11.1, the alpha subunit of a potassium ion channel. This ion channel (sometimes simply denoted as 'hERG') is best known for its contribution to the electrical activity of the heart: the hERG channel mediates the repolarizing ''I''Kr current in the cardiac action potential, which helps coordinate the heart's beating. When this channel's ability to conduct electrical current across the cell membrane is inhibited or compromised, either by application of drugs or by rare mutations in some families, it can result in a potentially fatal disorder called long QT syndrome. Conversely, genetic mutations that increase the current through these channels can lead to the related inherited heart rhythm disorder Short QT syndrome. A number of clinically successful drugs in the market have had the tendency to inhibit hERG, lengthening the QT and potentially leading to a fatal irregularity of the ...

Noribogaine
Noribogaine (actually O-desmethylibogaine), or 12-hydroxyibogamine, is the principal psychoactive metabolite of the oneirogen ibogaine. It is thought to be involved in the antiaddictive effects of ibogaine-containing plant extracts, such as '' Tabernanthe iboga''. Pharmacology Noribogaine is a potent serotonin reuptake inhibitor, but does not affect the reuptake of dopamine. Unlike ibogaine, noribogaine does not bind to the sigma-2 receptor. Similarly to ibogaine, noribogaine acts as a weak NMDA receptor antagonist and binds to opioid receptors. It has greater affinity for each of the opioid receptors than does ibogaine. Noribogaine is a hERG inhibitor and appears at least as potent as ibogaine. The inhibition of the hERG potassium channel delays the repolarization of cardiac action potentials, resulting in QT interval prolongation and, subsequently, in arrhythmias and sudden cardiac arrest. κ-Opioid receptor Noribogaine has been determined to act as a biased agon ...
