“Ecstasy” [(±)-3,4-methylenedioxymethamphetamine, MDMA, XTC, X, E] is a psychoactive recreational hallucinogenic substance and a major worldwide drug of abuse. Several reports raised the concern that MDMA has the ability to induce neurotoxic effects both in laboratory animals and humans. Despite more than two decades of research, the mechanisms by which MDMA is neurotoxic are still to be fully...

We have previously shown that (+/-)-3,4-methylenedioxymethamphetamine (MDMA) treatment from postnatal days (P)11 to P20 leads to learning and memory deficits when the animals are tested as adults. Recently, the club drug 5-methoxy-N,N-diisopropyltryptamine (5-MeO-DIPT) has gained popularity. Due to the similarities between MDMA and 5-MeO-DIPT and the substitution of 5-MeO-DIPT for MDMA, the...

The amphetamine derivative 3, 4-methylenedioxymethamphetamine (MDMA) has become a popular recreational drug, and has also been shown to cause serotonergic neurotoxicity. This report shows that MDMA impairs brain development in a whole mouse embryo culture. The results of quantitative real-time PCR analysis showed that autophagy-related protein 5 (Atg5) expression is elevated in mouse embryo and...

The amphetamine derivative (+/-)-3,4-methylenedioxymethamphetamine (MDMA or ecstasy) is a synthetic amphetamine analogue used recreationally to obtain an enhanced affiliative emotional response. MDMA is a potent monoaminergic neurotoxin with the potential to damage brain serotonin and/or dopamine neurons. As the majority of MDMA users are young adults, the risk that users may expose the fetus...

Repeated, intermittent exposure to the psychomotor stimulants amphetamine and cocaine induces a progressive and enduring augmentation of their locomotor-activating effects, known as behavioral sensitization, which is accompanied by similarly stable adaptations in the dendritic structure of cortico-striatal neurons. We examined whether repeated exposure to the increasingly abused amphetamine...

Background and purpose: We have investigated the ability of the β 3 ‐adrenoceptor antagonist 1‐(2‐ethylphenoxy)‐3‐[[(1S)‐1,2,3,4,‐tetrahydro‐1‐naphthalenyl]amino]‐(2S)‐2‐propanol hydrochloride (SR59230A) to affect the hyperthermia produced by methylenedioxymethamphetamine (MDMA) in conscious mice and whether α 1 ‐adrenoceptor antagonist actions are involved. Experimental approach: Mice were...

Commonly known as ecstasy, MDMA has been central to the British acid house, rave and dance club scene over the last 20 years. Figures from the annual national British Crime Survey suggest that ecstasy use has declined since 2001. This apparent decline is considered here alongside the concurrent emergence of a ‘new’ form of ecstasy ‐ MDMA powder or crystal ‐ and the extent to which this can be...

Exposure to stress alters the behavioral and neurochemical effects of drugs of abuse. However, it is unknown if chronic stress can affect the serotonergic depletions induced by the psychostimulant drug 3,4-methylenedioxymethamphetamine (MDMA). Rats were exposed to 10 days of chronic unpredictable stress (CUS) which resulted in the predicted elevation of basal plasma corticosterone...

Ecstasy (+/-3,4-methylenedioxymethamphetamine) is a widely used recreational drug that may damage the serotonin system and may entail neuropsychological dysfunctions. Few studies investigated predictors for ecstasy use. Self-reported impulsivity does not predict the initiation of ecstasy use; the question is if neuropsychological indicators of impulsivity can predict first ecstasy use. This...
