3,4-Methylenedioxyamphetamine is an empathogen-entactogen, psychostimulant, and psychedelic drug of the amphetamine family that is encountered mainly as a recreational drug. In its pharmacology, MDA is a serotonin–norepinephrine–dopamine releasing agent (SNDRA). In most countries, the drug is a controlled substance and its possession and sale are illegal.
3-Trifluoromethylphenylpiperazine (TFMPP) is a recreational drug of the phenylpiperazine chemical class and is a substituted piperazine. Usually in combination with benzylpiperazine (BZP) and other analogues, it is sold as an alternative to the illicit drug MDMA ("Ecstasy").
4-Methylaminorex is a stimulant drug of the 2-amino-5-aryloxazoline class that was first synthesized in 1960 by McNeil Laboratories. It is also known by its street name "U4Euh" ("Euphoria"). It is banned in many countries as a stimulant.
A monoamine releasing agent (MRA), or simply monoamine releaser, is a drug that induces the release of a monoamine neurotransmitter from the presynaptic neuron into the synapse, leading to an increase in the extracellular concentrations of the neurotransmitter. Many drugs induce their effects in the body and/or brain via the release of monoamine neurotransmitters, e.g., trace amines, many substituted amphetamines, and related compounds.
A norepinephrine releasing agent (NRA), also known as an adrenergic releasing agent, is a catecholaminergic type of drug that induces the release of norepinephrine (noradrenaline) and epinephrine (adrenaline) from the pre-synaptic neuron into the synapse. This in turn leads to increased extracellular concentrations of norepinephrine and epinephrine therefore an increase in adrenergic neurotransmission.
5-(2-Aminopropyl)indole is an indole and phenethylamine derivative with empathogenic effects. Its preparation was first reported by Albert Hofmann in 1962. It is a designer drug that has been openly sold as a recreational drug by online vendors since 2011.
Pentylone is a stimulant developed in the 1960s. It is a substituted cathinone. It has been identified in some samples of powders sold as "NRG-1", along with varying blends of other cathinone derivatives including flephedrone, MDPBP, MDPV and 4-MePPP. It was also found in combination with 4-MePPP being sold as "NRG-3". Reports indicate side effects include feelings of paranoia, agitation and inability to sleep, with effects lasting for several days at high doses.
6-APB is an empathogenic psychoactive compound 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. While the drug never became particularly popular, it briefly entered the rave and underground clubbing scene in the UK before its sale and import were banned. It falls under the category of research chemicals, sometimes called "legal highs." Because 6-APB and other substituted benzofurans have not been explicitly outlawed in some countries, they are often technically legal, contributing to their popularity.
Methoxetamine, abbreviated as MXE, is a dissociative hallucinogen that has been sold as a designer drug. It differs from many dissociatives such as ketamine and phencyclidine (PCP) that were developed as pharmaceutical drugs for use as general anesthetics in that it was designed specifically to increase the antidepressant effects of ketamine.
Methiopropamine (MPA) is an organic compound structurally related to methamphetamine. Originally reported in 1942, the molecule consists of a thiophene group with an alkyl amine substituent at the 2-position. It appeared for public sale in the UK in December 2010 as a "research chemical" or "legal high", recently branded as Blow. It has limited popularity as a recreational stimulant.
5-APB is an empathogenic psychoactive compound of the substituted benzofuran, substituted amphetamine and substituted phenethylamine classes. 5-APB and other compounds are sometimes informally called "Benzofury".
3,4-Dimethylmethcathinone (3,4-DMMC) is a stimulant drug first reported in 2010 as a designer drug analogue of mephedrone, apparently produced in response to the banning of mephedrone, following its widespread abuse in many countries in Europe and around the world. 3,4-DMMC has been seized as a designer drug in Australia. In vitro, 3,4-DMMC was shown to be a monoamine transporter substrate that potently inhibits norepinephrine and serotonin reuptake, and to a lesser extent dopamine reuptake.
Pentedrone is a stimulant of the cathinone class that has been sold as a designer drug and has been found since 2010 as an ingredient in a number of "bath salt" mixes sold as legal highs.
3-Methylmethcathinone, also known as 3-MMC and metaphedrone, is a designer drug from the substituted cathinone family. 3-MMC is closely related in structure to the more commonly known illicit drug mephedrone (4-MMC), and is also illegal in most countries that have banned mephedrone due to 3-MMC being a structural isomer of 4-MMC. However, 3-MMC has still appeared on the recreational drug market as an alternative to mephedrone, and was first identified being sold in Sweden in 2012. Unlike some synthetic cathinones, 3-MMC has been evaluated in a least one in large mammal study. 3-MMC is a monoamine transporter substrate that potently inhibits norepinephrine uptake and displays more pronounced dopaminergic vs. serotonergic activity.
N-Ethylhexedrone (also known as α-ethylaminocaprophenone, N-ethylnorhexedrone, hexen, and NEH) is a stimulant of the cathinone class that acts as a norepinephrine–dopamine reuptake inhibitor (NDRI) with IC50 values of 0.0978 and 0.0467 μM, respectively. N-Ethylhexedrone was first mentioned in a series of patents by Boehringer Ingelheim in the 1960s which led to the development of the better-known drug methylenedioxypyrovalerone (MDPV). Since the mid-2010s, N-ethylhexedrone has been sold online as a designer drug. In 2018, N-ethylhexedrone was the second most common drug of the cathinone class to be identified in Drug Enforcement Administration seizures.
2C-B-aminorex (2C-B-AR) is a recreational designer drug with psychedelic effects. It is a substituted aminorex derivative which was first identified in Sweden in June 2019.
4-Methylphenmetrazine is a recreational designer drug with stimulant effects. It is a substituted phenylmorpholine derivative, closely related to better known drugs such as phenmetrazine and 3-fluorophenmetrazine. It was first identified in Slovenia in 2015, and has been shown to act as a monoamine releaser with some preference for serotonin release.
4'-Fluoro-4-methylaminorex is a recreational designer drug from the substituted aminorex family, with stimulant effects. It was first detected in Slovenia in 2018. It was made illegal in Italy in March 2020.
3',4'-Methylenedioxy-4-methylaminorex (MDMAR) is a recreational designer drug from the substituted aminorex family, with monoamine releasing effects.
