Dimethoxybromoamphetamine (DOB), also known as brolamfetamine (INN) and bromo-DMA, is a psychedelic drug and substituted amphetamine of the phenethylamine class of compounds. DOB was first synthesized by Alexander Shulgin in 1967. Its synthesis and effects are documented in Shulgin's book PiHKAL: A Chemical Love Story.
para-Methoxyamphetamine (PMA), also known as 4-methoxyamphetamine (4-MA), is a designer drug of the amphetamine class with serotonergic effects. Unlike other similar drugs of this family, PMA does not produce stimulant, euphoriant, or entactogen effects, and behaves more like an antidepressant in comparison, though it does have some psychedelic properties.
4-Fluoroamphetamine, also known as para-fluoroamphetamine (PFA) is a psychoactive research chemical of the phenethylamine and substituted amphetamine chemical classes. It produces stimulant and entactogenic effects. As a recreational drug, 4-FA is sometimes sold along with related compounds such as 2-fluoroamphetamine and 4-fluoromethamphetamine.
4-Methylthioamphetamine (4-MTA) is a designer drug of the substituted amphetamine class developed in the 1990s by a team led by David E. Nichols, an American pharmacologist and medical chemist, at Purdue University. It acts as a non-neurotoxic highly selective serotonin releasing agent (SSRA) in animals. 4-MTA is the methylthio derivative of amphetamine.
(-)-1-Phenyl-2-propylaminopentane is a stimulant of the substituted phenethylamine class that has been derived from selegiline. When compared with selegiline and other substituted phenethylamines (-)-PPAP has a notably different mechanism of action and pharmacological effect.
Methedrone is a recreational drug of the cathinone chemical class. Chemically, methedrone is closely related to para-methoxymethamphetamine (PMMA), methylone and mephedrone. Methedrone received media attention in 2009 after the death of two young Swedish men. In both cases toxicology analysis showed methedrone was the only drug present in both men during the time of their overdose and subsequent deaths.
para-Chloroamphetamine (PCA), also known as 4-chloroamphetamine (4-CA), is a substituted amphetamine and monoamine releaser similar to MDMA, but with substantially higher neurotoxicity, thought to be due to the unrestrained release of both serotonin and dopamine by a metabolite. It is used as a neurotoxin by neurobiologists to selectively kill serotonergic neurons for research purposes, in the same way that 6-hydroxydopamine is used to kill dopaminergic neurons.
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.
4-Methylamphetamine is a stimulant and anorectic drug of the phenethylamine and amphetamine chemical classes.
para-Iodoamphetamine (PIA), also known as 4-iodoamphetamine (4-IA), is a research chemical of the phenethylamine and amphetamine chemical classes.
3-Methylamphetamine is a stimulant drug from the amphetamine family. It is self-administered by mice to a similar extent to 4-fluoroamphetamine and has comparable properties as a monoamine releaser, although with a more balanced release of all three monoamines, as opposed to the more dopamine/noradrenaline selective fluoro analogues.
3-Fluoroamphetamine is a stimulant drug from the amphetamine family which acts as a monoamine releaser with similar potency to methamphetamine but more selectivity for dopamine and norepinephrine release over serotonin. It is self-administered by mice to a similar extent to related drugs such as 4-fluoroamphetamine and 3-methylamphetamine.
2-Fluoroamphetamine (2-FA) is a stimulant drug from the amphetamine family which has been sold as a designer drug. 2-Fluoroamphetamine differs from 3- and 4-fluoroamphetamine in the position of the fluorine atom on the aromatic ring, making them positional isomers of one another. The replacement of a hydrogen atom with a fluorine atom in certain compounds to facilitate passage through the blood–brain barrier, as is desirable in central nervous system pharmaceutical agents, is a common practice due to the corresponding increase in lipophilicity granted by this substitution.
meta-Methoxyamphetamine (MMA), also known as 3-methoxyamphetamine (3-MA), is a stimulant drug from the amphetamine family. It has similar effects in animal drug discrimination tests to the more widely known derivative 4-methoxyamphetamine (PMA), although with a slightly different ratio of monoamine release, being a combined serotonin, dopamine, and norepinephrine releasing agent rather than a fairly selective serotonin releaser like PMA. 3-Methoxyamphetamine has similarly appeared on the illicit market as a designer drug alternative to MDMA, although far more rarely than its infamous positional isomer. It produces gepefrine, a cardiac stimulant, as one of its major metabolites.
2,5-Dimethoxy-4-fluoroamphetamine (DOF) is a psychedelic drug of the phenethylamine and amphetamine classes. Alexander Shulgin briefly describes DOF in his book PiHKAL:
Animal studies that have compared DOF to the highly potent DOI and DOB imply that the human activity will be some four to six times less than these two heavier halide analogues.
3-Fluoroethamphetamine (3-FEA) is a stimulant drug of the amphetamine class which acts as a releasing agent of the monoamine neurotransmitters norepinephrine, dopamine and serotonin.
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.
Substituted tryptamines, or serotonin analogues, are organic compounds which may be thought of as being derived from tryptamine itself. The molecular structures of all tryptamines contain an indole ring, joined to an amino (NH2) group via an ethyl (−CH2–CH2−) sidechain. In substituted tryptamines, the indole ring, sidechain, and/or amino group are modified by substituting another group for one of the hydrogen (H) atoms.
para-Chloromethamphetamine is a stimulant that is the N-methyl derivative and prodrug of the neurotoxic drug para-chloroamphetamine (4-CA). It has been found to decrease serotonin in rats. Further investigation into the long-term effects of chloroamphetamines discovered that administration of 4-CMA caused a prolonged reduction in the levels of serotonin and the activity of tryptophan hydroxylase in the brain one month after injection of a single dose of the drug.
