3-APBT (former developmental code name SKF-6678), also known as 3-(2-aminopropyl)benzo[β]thiophene, is a monoamine releasing agent and serotonin receptor agonist of the benzothiophene group.[1][2] It is an analogue of α-methyltryptamine (AMT) in which the indole ring has been replaced with a benzothiophene ring.[1][2]
The drug acts as a potent and well-balanced serotonin–norepinephrine–dopamine releasing agent (SNDRA).[2] It is also a full agonist of the serotonin 5-HT2 receptors, including of the serotonin 5-HT2A, 5-HT2B, and 5-HT2C receptors.[2] 3-APBT produces the head-twitch response, a behavioral proxy of psychedelic effects, in rodents.[2] It does not stimulate locomotor activity in rodents, suggesting that it does not possess stimulant-type effects.[2] The drug has been reported be a weak monoamine oxidase inhibitor (MAOI), specifically of monoamine oxidase A (MAO-A) (IC50Tooltip half-maximal inhibitory concentration = 16,200 nM).[2][3]
3-APBT was developed by Smith, Kline & French (SKF) as a potential pharmaceutical drug in the late 1950s.[1][4] The drug and its positional isomer 2-APBT were reported to produce various central nervous system (CNS) effects and to be useful as a "ataractics, psychic energizers, and analgetics".[1][4] 3-APBT has also been reported to have appetite suppressant effects in rodents, but to have considerably lower potency than AMT as an "analeptic" in rodents.[1][5]
