6-APDB is a stimulant and entactogen drug of the phenethylamine and amphetamine classes. Buy high quality 6-APDB online from EU. 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. It is an analogue of MDA where the heterocyclic 4-position oxygen from the 3,4-methylenedioxy ring has been replaced with a methylene bridge
6-APDB (also known as 6-(2-aminopropyl)-2,3-dihydrobenzofuran or 4-Desoxy-MDA) is a stimulant and entactogenic research chemical of the phenethylamine and benzofuran classes. It is a closely related synthetic analogue of MDA and 6-APB and broadly shares the characteristics of serotonin-selective triple monoamine releasers and reuptake inhibitors associated with other entactogenic or empathogenic compounds.
6-APDB was first synthesized and studied along with 5-APDB in 1993 by David E. Nichols as a potential non-neurotoxic alternative to MDMA. It did not come into popular recreational use until over a decade later, where it briefly entered the rave scene and global research chemicals market, in particular the “legal highs” market in the U.K., before its sale and import were subsequently banned.
Because 4-Desoxy-MDA and other substituted benzofurans have not been explicitly outlawed in some countries, they are often technically legal, contributing to their popularity as a substitute or replacement for serotonergic entactogens like MDMA or MDA, and are typically distributed through the online research chemicals grey market.
5-APDB (3-Desoxy-MDA) is an analogue of 6-APDB where the 3-position oxygen has been replaced with a methylene instead. 6-APDB, along with 5-APDB, was first synthesized by David E. Nichols in the early 1990s while investigating non-neurotoxic MDMA analogues.
In animal studies, 6-APDB fully substitutes for MBDB and MMAI but not for amphetamine or LSD. In vitro, 6-APDB has been shown to inhibit the reuptake of serotonin, dopamine, and norepinephrine with IC50 values of 322 nM, 1,997 nM, and 980 nM, respectively. These values are very similar to those of MDA, but with those for the catecholamines slightly lower in comparison, perhaps more similarly to MDMA. In contrast, 5-APDB is highly selective for serotonin. Though 4-Desoxy-MDA 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.
