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
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
Treatment of drug dependence
Ibogaine and related alkaloids reduce the craving for subsequent doses in individuals experiencing withdrawal symptoms associated with drug addiction. Their use has been investigated in several clinical studies involving individuals dependent on opioids, cocaine, and other substances. While positive effects—such as alleviation of withdrawal symptoms, improvement in depression, and mitigation of post-traumatic symptoms—have been confirmed, severe medical complications, including fatal cases, have also been reported due to neurotoxic and cardiotoxic side effects.[5]
Synthetic analogues
18-MC, ME-18-MC, and 18-MAC are coronaridine analogs with similar anti-addictive effects.[6][7][8][9]
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".[10]
