Ibogaminalog (developmental code name DM-506) is a non-selective and non-psychedelic serotonin receptor modulator of the ibogalog group related to the iboga alkaloid ibogamine but with a simplified chemical structure. It was first described in the 1960s but was subsequently further studied and reported on in the 2020s.
Ibogaminalog is known to act as an agonist of serotonin receptors, including of the serotonin 5-HT<sub>2A</sub> receptor (K<sub>i</sub> = 17âÂÂ11,190nM; = 2.9âÂÂ34nM; = 33âÂÂ76%), the serotonin 5-HT<sub>2B</sub> receptor (K<sub>i</sub> = 16.5âÂÂ63,780nM; = 2.9âÂÂ33nM; = 68âÂÂ69%), and the serotonin 5-HT<sub>6</sub> receptor ( = 2.9nM; = 96%), and as an inverse agonist of the serotonin 5-HT<sub>7</sub> receptor ( = 14%).
It is a weak to very weak monoamine reuptake inhibitor, including of serotonin, norepinephrine, and dopamine ( = 3,100nM, 9,500nM, and 70,000nM, respectively), whereas it is not a significant monoamine oxidase inhibitor (MAOI) of MAO-A or MAO-B. The drug also acts weakly as a negative allosteric modulator of the ñ<sub>7</sub> and ñ<sub>9</sub>ñ<sub>10</sub> nicotinic acetylcholine receptors.
Ibogaminalog does not produce the head-twitch response, a behavioral proxy of psychedelic effects, in rodents, and hence may be non-hallucinogenic in humans. On the other hand, it has been found to produce sedative, antidepressant-like, anxiolytic-like, antiaddictive-like, and analgesic-like effects in rodents.
