Tabernanthalog is a non-hallucinogenic serotonin 5-HT2A receptor agonist.[3] It is also a serotonin 5-HT2B receptor antagonist.[3] The drug is described as having high selectivity for the serotonin 5-HT2 receptors.[3] Other targets of the drug include monoamine oxidase A (MAO-A), the α2A-adrenergic receptor, the serotonin 5-HT1B and 5-HT2C receptors, and the serotonin transporter (SERT).[3]

In rodents, it was found to promote structural neural plasticity, reduce drug seeking behavior, and produce antidepressant like effects.[1][4][5][6] It has also been shown that it effectively reduces motivation for heroin and alcohol in rats. This indicates its efficacy in animals with a history of heroin and alcohol polydrug use.[6]

Due to the rapidly-induced and enduring neuroplasticity, tabernanthalog is a member of the class of compounds known as non-hallucinogenic psychoplastogens.[1] This compound, as well as related compounds, are licensed by Delix Therapeutics and are being developed as potential medicines for neuropsychiatric disorders.[7]
