Iboga-type alkaloids are a set of monoterpene indole alkaloids comprising naturally occurring compounds found in Tabernanthe and Tabernaemontana, as well as synthetic structural analogs. Naturally occurring iboga-type alkaloids include ibogamine, ibogaine, tabernanthine, and other substituted ibogamines (). Many iboga-type alkaloids display biological activities such as cardiac toxicity and psychoactive effects, and some have been studied as potential treatments for drug addiction.[1][2]

Catharanthine is an unsaturated analog of coronaridine.
Oxidation products
[edit]Similarly to other ring-constrained tryptamines such as yohimbine[3] and mitragynine (see mitragynine pseudoindoxyl), oxidation and rearrangement products of substituted ibogamines have been reported, such as iboluteine (ibogaine pseudoindoxyl) (CID:21589055) and voaluteine (CID:633439).[4]
Other alkaloids
[edit]Synthetic analogs
[edit]18-MC, ME-18-MC, and 18-MAC are coronaridine analogs with similar anti-addictive effects.[5][6][7][8]
More distantly related synthetic analogs include :
- Varenicline, a polycyclic azepine and anti-addictive agent that similarly targets nicotinic acetylcholine receptors, but acts as a partial agonist instead.
- Tabernanthalog is a structural simplification of tabernanthine and "non-hallucinogenic psychoplastogen".[9]
