3-APBT (former developmental code nameSKF-6678), also known as3-(2-aminopropyl)benzo[β]thiophene, is amonoamine releasing agent andserotonin receptor agonist of thebenzothiophene group.[1][2] It is ananalogue ofα-methyltryptamine (AMT) in which theindolering has been replaced with abenzothiophene ring.[1][2]

The drug acts as apotent and well-balancedserotonin–norepinephrine–dopamine releasing agent (SNDRA).[2] It is also afull agonist of theserotonin5-HT2 receptors, including of the serotonin5-HT2A,5-HT2B, and5-HT2C receptors.[2] 3-APBT produces thehead-twitch response, a behavioral proxy ofpsychedelic effects, in rodents.[2] It does notstimulate locomotor activity in rodents, suggesting that it does not possessstimulant-type effects.[2] The drug has been reported be a weakmonoamine oxidase inhibitor (MAOI), specifically ofmonoamine oxidase A (MAO-A) (IC50Tooltip half-maximal inhibitory concentration = 16,200 nM).[2][3]

3-APBT was developed bySmith, Kline & French (SKF) as a potentialpharmaceutical drug in the late 1950s.[1][4] The drug and itspositional isomer2-APBT were reported to produce variouscentral nervous system (CNS) effects and to be useful as a "ataractics, psychic energizers, and analgetics".[1][4] 3-APBT has also been reported to haveappetite suppressant effects in rodents, but to have considerably lower potency than AMT as an "analeptic" in rodents.[1][5]
