5-(2-Aminopropyl)-2,3-dihydrobenzofuran (5-APDB, 3-Desoxy-MDA, EMA-4) is a putative entactogen drug of the phenethylamine and amphetamine classes.[1] It is an analogue of MDA where the heterocyclic 3-position oxygen from the 3,4-methylenedioxy ring has been replaced by a methylene bridge.[1] 6-APDB is an analogue of 5-APDB where the 4-position oxygen has been replaced by a methylene bridge instead.[1] 5-APDB was developed by a team led by David E. Nichols at Purdue University as part of their research into non-neurotoxic analogues of MDMA.[1]

In animal studies, 5-APDB's effects generalize most closely to non-stimulant MDMA analogues such as MBDB and MMAI, while producing no substitution for LSD or amphetamine.[1] In vitro studies show that 5-APDB acts as a highly selective serotonin releasing agent (SSRA), with IC50 values of 130 nM, 7,089 nM, and 3,238 nM for inhibiting the reuptake of serotonin, dopamine, and norepinephrine, respectively.[1] In contrast, 6-APDB is more balanced on the three monoamine neurotransmitters and acts more similarly to MDA and MDMA.[1] Anecdotal reports from human users suggest that 5-APDB produces mild empathy but with relatively little euphoria and is accompanied by sedation.

Methoxy-substituted analogues of 5-APDB and 6-APDB have also been made and substituted for DOM in animal tests, although they were around 10x less potent than DOM.[2][3]

Legal Status

China

As of October 2015 5-APDB is a controlled substance in China.[4]

UK

On June 10, 2013 5-APDB and a number of analogues were classified as Temporary Class Drugs in the UK following an ACMD recommendation.[5] This means that sale and import of the named substances are criminal offences and are treated as for class B drugs.[6]
