5-MAPB

5-MAPB (1-(benzofuran-5-yl)-N-methylpropan-2-amine) is an entactogenic designer drug similar to MDMA in its structure and effects.[1]

Canada

5-MAPB is not listed itself in the CDSA but since it is structurally related to MDMA it may be considered illegal in Canada, although this has not been tested in court.[2]

China

As of October 2015 5-MAPB is a controlled substance in China.[3]

United Kingdom

5-MAPB was originally banned in the UK in June 2013 under a Temporary class drug order.[4] On March 5, 2014 the UK Home Office announced that 5-MAPB would be made a class B drug on 10 June 2014 alongside every other benzofuran entactogen and many structurally related drugs.[5]

Pharmacokinetics

Metabolism and toxicity

Little formal knowledge exists on 5-MAPB. It does not share the neurotoxicity of MDMA or MDA caused by the alpha-methyldopamine metabolite.[6][7][8] A study in rats indicated that the major metabolites of 5-MAPB are 5-APB and 3-carboxymethyl-4-hydroxymethamphetamine.[9]

Pharmacodynamics

5-MAPB binds to the dopamine transporter in rat brain cells with a lower potency than cocaine. In silico data suggests that the primary action on dopamine is through reversal of the transporter to release dopamine. This is consistent with the effects and it is likely that it exerts a similar action on serotonin and norepinephrine transporters.[10]
