6-(2-Aminopropyl)-2,3-dihydrobenzofuran (6-APDB, 4-Desoxy-MDA, EMA-3) is a stimulant and entactogen drug of the phenethylamine and amphetamine classes.^[1] It is an analogueofMDA where the heterocyclic 4-position oxygen from the 3,4-methylenedioxy ring has been replaced with a methylene bridge.^[1] 5-APDB (3-Desoxy-MDA) is an analogue of 6-APDB where the 3-position oxygen has been replaced with a methylene instead.^[1] 6-APDB, along with 5-APDB, was first synthesizedbyDavid E. Nichols in the early 1990s while investigating non-neurotoxic MDMA analogues.^[1]

In animal studies, 6-APDB fully substitutes for MBDB and MMAI but not for amphetamineorLSD.^[1] In vitro, 6-APDB has been shown to inhibit the reuptakeofserotonin, dopamine, and norepinephrine with IC₅₀ values of 322 nM, 1,997 nM, and 980 nM, respectively.^[1] These values are very similar to those of MDA, but with those for the catecholamines slightly lower in comparison, perhaps more similarly to MDMA.^[1] In contrast, 5-APDB is highly selective for serotonin.^[1] Though 6-APDB does not substitute for amphetamine in rats at the doses used in referenced study, based on its in vitro profile it can be suggested that it may have amphetamine-like effects at higher doses.

The unsaturated benzofuran derivative 6-APB, or 6-(2-aminopropyl)benzofuran is also known, but the difference in pharmacological effects between 6-APB and 6-APDB is unclear.

6-APDB is a class B drug in the UK since June 10, 2013. It is banned by a blanket law on benzofurans and related compounds.^[2]
