6-(2-Aminopropyl)-1-benzothiophene (6-APBT) is a monoamine releasing agent and serotonin receptor agonist of the amphetamine and benzothiophene families.12 It is related to MDA and other MDA bioisosteres like the benzofurans.12
The drug acts as a potent and well-balanced serotonin–norepinephrine–dopamine releasing agent (SNDRA) and full agonist of the serotonin 5-HT2 receptors.2 6-APBT does not increase locomotor activity in rodents and hence does not appear to have stimulant-like effects.2 However, it does produce the head-twitch response, a behavioral proxy of psychedelic effects, and hence may have hallucinogenic effects.2 The drug is a potent monoamine oxidase inhibitor (MAOI), specifically of monoamine oxidase A (MAO-A) (IC50Tooltip half-maximal inhibitory concentration = 600 nM).3
6-APBT was first described in the scientific literature by 2020.12
