SeDMA is a bioisosteric analogue of 3,4-methylenedioxy-N-methylamphetamine (MDMA) which was developed in an attempt to create an improved MDMA alternative for potential clinical use. [1] It is the analogue of MDMA in which the 1,3-benzodioxole ring has been replaced with a 2,1,3-benzoselenadiazole ring. [1] ODMA and TDMA are closely related analogues. [1] ODMA, TDMA, and SeDMA are releasing agents of serotonin, norepinephrine, and dopamine similarly to MDMA. [1] However, they are less potent and efficacious in activating the serotonin 5-HT2A, 5-HT2B, and 5-HT2C receptors than MDMA and show differing and potentially improved metabolic and pharmacokinetic properties in comparison. [1] ODMA, TDMA, and SeDMA were first described in the scientific literature in June 2024. [1]
MDMA and 3,4-methylenedioxyamphetamine (MDA) are well-known serotonergic neurotoxins that damage serotonergic neurons in the brain. [2] [3] [4] [5] [6] However, MDMA and MDA injected directly into the brain have been found to not produce serotonergic neurotoxicity in rodents. [2] [7] [8] This suggests that peripherally formed metabolites of MDMA and MDA may be the actual mediators of the neurotoxicity rather than MDMA and MDA themselves. [2] [7] [8] ODMA, TDMA, and SeDMA, with the exception of N-demethylation, do not share any of the phase I or phase II metabolic pathways of MDMA. [1] Notably, in contrast to MDMA, methylenedioxy ring opening and consequent formation of catechol metabolites, which have been linked with free radical generation, does not occur. [1] As a result, ODMA, TDMA, and SeDMA might not share the serotonergic neurotoxicity of MDMA and MDA. [1] However, more research is needed to assess this possibility. [1] Moreover, other studies have found that slow infusion of MDMA directly into the brain does produce signs of serotonergic neurotoxicity. [9]

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.
3,4-Methylenedioxyamphetamine (MDA), sometimes referred to as sass, is an empathogen-entactogen, stimulant, 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.
MBDB, also known as N-methyl-1,3-benzodioxolylbutanamine or as 3,4-methylenedioxy-N-methyl-α-ethylphenylethylamine, is an entactogen of the phenethylamine, amphetamine, and phenylisobutylamine families related to MDMA. It is known by the street names "Eden" and "Methyl-J".
Methylone, also known as 3,4-methylenedioxy-N-methylcathinone (MDMC), is an empathogen and stimulant psychoactive drug. It is a member of the amphetamine, cathinone and methylenedioxyphenethylamine classes.
3,4-Ethylenedioxy-N-methylamphetamine (EDMA) is an entactogen drug of the methamphetamine class. It is an analogue of MDMA where the methylenedioxy ring has been replaced by an ethylenedioxy ring. EDMA was first synthesized by Alexander Shulgin. In his book PiHKAL, the dosage is listed as 150–250 mg, and the duration listed as 3–5 hours. According to Shulgin, EDMA produces a bare threshold consisting of paresthesia, nystagmus, and hypnogogic imagery, with few to no other effects.
1,3-Benzodioxolylbutanamine is an entactogenic drug of the phenethylamine, amphetamine, and phenylisobutylamine families. It is the α-ethyl analog of MDPEA and MDA and the methylenedioxy analogue of α-ethylphenethylamine.
MDAI, also known as 5,6-methylenedioxy-2-aminoindane, is an entactogen drug of the 2-aminoindane group which is related to MDMA and produces similar subjective effects.
5-Methoxy-6-methyl-2-aminoindane (MMAI) is a drug of the 2-aminoindane group developed in the 1990s by a team led by David E. Nichols at Purdue University. It acts as a less neurotoxic and highly selective serotonin releasing agent (SSRA) and produces entactogenic effects in humans. It has been sold as a designer drug and research chemical online since 2010.
α-Methyldopamine (α-Me-DA), also known as 3,4-dihydroxyamphetamine or as catecholamphetamine, is a research chemical of the catecholamine and amphetamine families. It is a monoamine releasing agent and a metabolite of MDMA and MDA. The bis-glutathionyl metabolite of α-methyldopamine is slightly neurotoxic when directly injected into the brain's ventricles.
4-Chlorophenylisobutylamine, also known as 4-chloro-α-ethylphenethylamine, is an entactogen and stimulant drug of the phenethylamine, amphetamine, and phenylisobutylamine families. It is an analogue of para-chloroamphetamine (PCA) where the alpha position methyl has been replaced with an ethyl group.
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.
5-MAPB, also known as 5-(N-methyl-2-aminopropyl)benzofuran, is an entactogen and designer drug of the amphetamine family that is similar to MDMA in its structure and effects.
2,3-Methylenedioxymethamphetamine (2,3-MDMA), also known as ORTHO-MDMA, is a positional isomer of the recreational drug 3,4-MDMA. It is a monoamine transporter (MAT) substrate and inhibitor similarly to 3,4-MDMA. However, while showing similar potency at the norepinephrine transporter (NET), 2,3-MDMA is less potent at the serotonin transporter (SERT). 2,3-MDMA has not been encountered as a recreational or designer drug.
A monoamine neurotoxin, or monoaminergic neurotoxin, is a drug that selectively damages or destroys monoaminergic neurons. Monoaminergic neurons are neurons that signal via stimulation by monoamine neurotransmitters including serotonin, dopamine, and norepinephrine.
ODMA is a bioisosteric analogue of 3,4-methylenedioxy-N-methylamphetamine (MDMA) which was developed in an attempt to create an improved MDMA alternative for potential clinical use. It is the analogue of MDMA in which the 1,3-benzodioxole ring has been replaced with a 2,1,3-benzoxadiazole ring. TDMA and SeDMA are closely related analogues. ODMA, TDMA, and SeDMA are releasing agents of serotonin, norepinephrine, and dopamine similarly to MDMA. However, they are less potent and efficacious in activating the serotonin 5-HT2A, 5-HT2B, and 5-HT2C receptors than MDMA and show differing and potentially improved metabolic and pharmacokinetic properties in comparison. ODMA, TDMA, and SeDMA were first described in the scientific literature in June 2024.
TDMA is a bioisosteric analogue of 3,4-methylenedioxy-N-methylamphetamine (MDMA) which was developed in an attempt to create an improved MDMA alternative for potential clinical use. It is the analogue of MDMA in which the 1,3-benzodioxole ring has been replaced with a 2,1,3-benzothiadiazole ring. ODMA and SeDMA are closely related analogues. ODMA, TDMA, and SeDMA are releasing agents of serotonin, norepinephrine, and dopamine similarly to MDMA. However, they are less potent and efficacious in activating the serotonin 5-HT2A, 5-HT2B, and 5-HT2C receptors than MDMA and show differing and potentially improved metabolic and pharmacokinetic properties in comparison. ODMA, TDMA, and SeDMA were first described in the scientific literature in June 2024.
3,4-Dihydroxymethamphetamine, or 3,4-dihydroxy-N-methylamphetamine, also known as α-methylepinine or α,N-dimethyldopamine, is the major metabolite of 3,4-methylenedioxy-N-methylamphetamine (MDMA). It is formed from MDMA by O-demethylation via cytochrome P450 enzymes including CYP2D6 as well as CYP1A2 and CYP3A4. Like MDMA, HHMA is a monoamine releasing agent.
The Borax combo, also known by the informal brand names Blue Bliss and Pink Star, is a combination recreational and designer drug described as an MDMA-like entactogen.
3,4-Isopropylidenedioxyamphetamine (IDA) is a monoamine releasing agent (MRA) of the amphetamine family related to 3,4-methylenedioxyamphetamine (MDA). It is considerably less potent than MDA as an MRA in vitro. IDA fully substituted for MDMA and LSD in animal drug discrimination tests, albeit with 5- to 7-fold lower potency than MDA.
While a single injection of MDMA into the brain (intracerebroventricularly) had no effect on TPH activity, slow infusion of 1 mg/kg MDMA into the brain over 1 hr produced enough oxidative stress to acutely reduce TPH activity (Schmidt and Taylor 1988). The acute decrease in TPH activity is an early effect of MDMA and can be measured at post 15 min (Stone et al. 1989b). TPH inactivation can also be produced by non-neurotoxic MDMA doses (Schmidt and Taylor 1988; Stone et al. 1989a; Stone et al. 1989b). It therefore appears that MDMA rapidly induces oxidative stress but only produces neurotoxicity when endogenous free radical scavenging systems are overwhelmed.
