5-(2-aminopropyl)benzofuran or 1-benzofuran-5-ylpropan-2-amine (5-APB) is a triple monoamine reuptake inhibitor with K_i values of 180, 265 and 811 for NET, DAT and SERT respectively as well as being a potent agonist for the 5-HT_2B receptor (K_i 14nM).^[1] This agonism for 5-HT_2B makes it likely that 5-APB would be cardiotoxic with long term use, as seen in other 5-HT_2B agonists such as fenfluramine and MDMA. The subjective effects and structure-activity relationship suggest that 5-APB is also a monoamine releasing agent. Preliminary evidence suggests 5-APB is an inhibitor of the CYP2D6 enzyme.^[2]

5-APB is commonly found as the succinate and hydrochloride salt. The hydrochloride salt is 10% more potent by mass and doses should be adjusted accordingly.

5-APB is also an agonist of the 5-HT_2C receptor ^[3] as well as a triple monoamine reuptake inhibitor.^[1] It has been sold as a designer drug since 2010.^[4] Anecdotal reports from users suggest it has stimulant and empathogenic effects, but less psychedelic action than related compounds such as 6-APB and 5-APDB.^{[citation needed]}

Detection

A forensic standard of 5-APB is available, and the compound has been posted on the Forendex website of potential drugs of abuse.^[5] The US Department of Justice and DEA have also conducted studies concerning the detection of 5-APB.^[6]

Effects

Users describe effects as euphoric. Largely, effects reported were similar to that of the drug MDA but not as strong.
