6-MBPB, also known as 6-(2-methylaminobutyl)benzofuran (6-MABB), is a monoamine releasing agent (MRA) and entactogen-like drug of the amphetamine, phenylisobutylamine, and benzofuran families.

[1][2][3][4][5] The drug appears to act as a serotonin–norepinephrine–dopamine releasing agent (SNDRA).

[1][2] The EC50Tooltip half-maximal effective concentration values for induction of monoamine release in rat brain synaptosomes have been reported for the individual enantiomers of 6-MBPB.

[2] The enantiomers showed a mixed profile of acting as full versus partial releasers.

[2] 6-MBPB partially substituted for MDMA in animal drug discrimination tests at lower doses and fully substituted for MDMA at the highest dose, suggesting that it has entactogen-like effects.
