Tabernanthine is an alkaloid found in Tabernanthe iboga . ^[1]

It has been used in laboratory experiments to study how addiction affects the brain. ^[2]

Tabernanthine persistently reduced the self-administration of cocaine and morphine in rats. ^[3]

Pharmacology

It is kappa opioid agonist (K_i = 0.15 μM) and NMDA receptor (K_i = 10.5 μM) antagonist. ^{[4] [5]} Compared to ibogaine, it binds weakly to σ₁ and σ₂ receptor. ^[5]
