Pharmacology

Pharmacodynamics

5-MAPB acts as a serotonin–norepinephrine–dopamine releasing agent with EC50 Tooltip half-maximal effective concentration values for induction of monoamine release of 64 nM for serotonin, 24 nM for norepinephrine, and 41 nM for dopamine. [2] [3] [4] [5] It is also a partial agonist of the serotonin 5-HT2A, 5-HT2B, and 5-HT2C receptors. [2] [3] [6]

5-MAPB has been described by Matthew Baggott as the MDMA analogue so far known that has the closest effects and so-called "magic" to MDMA itself. [8] [9] Other analogues that lack the full quality of MDMA include MBDB, methylone, 6-APDB, 5-APDB, 6-APB, 5-APB, MDAT, and MDAI, among others. [8] [9]

5-MAPB has been marketed as a less- or non-neurotoxic alternative to MDMA. [10] However, 5-MAPB has been found to be a dose-dependent serotonergic neurotoxin in rodents similarly to MDMA, and might also be a dopaminergic neurotoxin. [10]

Pharmacokinetics

Little formal knowledge exists on 5-MAPB. It does not form the α-methyldopamine metabolite that contributes to the neurotoxicity of MDMA or MDA. [11] [12] [13] [14] A study in rats indicated that the major metabolites of 5-MAPB are 5-APB and 3-carboxymethyl-4-hydroxymethamphetamine. [15]

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. [16]

China

As of October 2015 5-MAPB is a controlled substance in China. [17]

Luxembourg

As of July 2021, 5-MAPB is not cited in the list of prohibited substances. [18] Therefore, it is still a legal substance.

United Kingdom

5-MAPB was originally banned in the UK in June 2013 under a Temporary class drug order. [19] 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. [20]

<span class="mw-page-title-main">Empathogen</span> Class of psychoactive drugs that produce empathic experiences

Empathogens or entactogens are a class of psychoactive drugs that induce the production of experiences of emotional communion, oneness, relatedness, emotional openness—that is, empathy or sympathy—as particularly observed and reported for experiences with 3,4-methylenedioxymethamphetamine (MDMA). This class of drug is distinguished from the classes of hallucinogen or psychedelic, and amphetamine or stimulants. Major members of this class include MDMA, MDA, MDEA, MDOH, MBDB, 5-APB, 5-MAPB, 6-APB, 6-MAPB, methylone, mephedrone, GHB, αMT, and αET, MDAI among others. Most entactogens are phenethylamines and amphetamines, although several, such as αMT and αET, are tryptamines. When referring to MDMA and its counterparts, the term MDxx is often used. Entactogens are sometimes incorrectly referred to as hallucinogens or stimulants, although many entactogens such as ecstasy exhibit psychedelic or stimulant properties as well.

<span class="mw-page-title-main">Monoamine releasing agent</span> Class of compounds

A monoamine releasing agent (MRA), or simply monoamine releaser, is a drug that induces the release of one or more monoamine neurotransmitters from the presynaptic neuron into the synapse, leading to an increase in the extracellular concentrations of the neurotransmitters and hence enhanced signaling by those neurotransmitters. The monoamine neurotransmitters include serotonin, norepinephrine, and dopamine; monoamine releasing agents can induce the release of one or more of these neurotransmitters.

A serotonin–norepinephrine–dopamine releasing agent (SNDRA), also known as a triple releasing agent (TRA), is a type of drug which induces the release of serotonin, norepinephrine/epinephrine, and dopamine in the brain and body. SNDRAs produce euphoriant, entactogen, and psychostimulant effects, and are almost exclusively encountered as recreational drugs.

<span class="mw-page-title-main">6-APB</span> Psychoactive drug

6-APB is an empathogenic psychoactive drug of the substituted benzofuran and substituted phenethylamine classes. 6-APB and other compounds are sometimes informally called "Benzofury" in newspaper reports. It is similar in structure to MDA, but differs in that the 3,4-methylenedioxyphenyl ring system has been replaced with a benzofuran ring. 6-APB is also the unsaturated benzofuran derivative of 6-APDB. It may appear as a tan grainy powder.

<span class="mw-page-title-main">DFMDA</span> Chemical compound

Difluoromethylenedioxyamphetamine is a substituted derivative of 3,4-methylenedioxyamphetamine (MDA), which was developed by Daniel Trachsel and coworkers, along with the corresponding fluorinated derivatives of MDMA, MDEA, BDB and MBDB, with the aim of finding a non-neurotoxic drug able to be used as a less harmful substitute for entactogenic drugs such as MDMA. Since a major route of the normal metabolism of these compounds is scission of the methylenedioxy ring, producing neurotoxic metabolites such as alpha-methyldopamine, it was hoped that the difluoromethylenedioxy bioisostere would show increased metabolic stability and less toxicity.

Society for Neuroscience Conference, Nov. 14, 2022, San Diego, CA. 5-MAPB has been marketed as a less neurotoxic analogue of MDMA, but no studies have addressed whether 5-MAPB can cause the long lasting serotonergic changes seen with high or repeated MDMA dosing. [...] Neurochemical analyses indicated a statistically significant reduction in 5‑HT and 5-HIAA in all brain regions assessed 24 hours and two weeks after 6 mg/kg 5‑MAPB, with no statistically significant differences in monoamine levels between 1.2 mg/kg and saline-treated rats. There were also non-significant trends for reductions in striatal dopamine at both time intervals after 6 mg/kg 5-MAPB. These results show that 5-MAPB can dose-dependently produce persistent changes in 5-HT and 5-HIAA that appear analogous to those produced by MDMA.
