3,4-Methylenedioximethamphetamine (MDMA; "ecstasy") is a psychotropic drug with well-known neurotoxic effects mediated by hitherto not fully understood mechanisms. The Na+- and K+-activated adenosine 5'-triphosphatase (Na+/K+ ATPase), by maintaining the ion gradient across the cell membrane, regulates neuronal excitability. Thus, a perturbation of its function strongly impacts cell homeostasis,...
3,4-Methylenedioxymethamphetamine (MDMA; "ecstasy") is a potentially neurotoxic recreational drug of abuse. Though the mechanisms involved are still not completely understood, formation of reactive metabolites and mitochondrial dysfunction contribute to MDMA-related neurotoxicity. Neuronal mitochondrial trafficking, and their targeting to synapses, is essential for proper neuronal function and...
3,4-Methylenedioxymethamphetamine (MDMA; "ecstasy") is a recreational hallucinogenic drug of abuse known to elicit neurotoxic properties. Hepatic formation of neurotoxic metabolites is thought to play a major role in MDMA-related neurotoxicity, though the mechanisms involved are still unclear. Here, we studied the neurotoxicity mechanisms and stability of MDMA and 6 of its major human...

"Ecstasy" (3,4-methylenedioxymethamphetamine or MDMA) is a widely abused recreational drug, reported to produce neurotoxic effects, both in laboratory animals and in humans. MDMA metabolites can be major contributors for MDMA neurotoxicity. This work studied the neurotoxicity of MDMA and its catechol metabolites, α-methyldopamine (α-MeDA) and N-methyl-α-methyldopamine (N-Me-α-MeDA) in human...
3,4-Methylenedioxymethamphetamine (MDMA; ecstasy), a drug of abuse commonly consumed at rave parties, is often taken in a polydrug abuse scenario, ethanol being one of the most associated drugs. Both MDMA and ethanol are mainly metabolized in the liver with formation of toxic metabolites. Our working hypothesis is that ethanol can modify the metabolism of MDMA through the cytochrome P450...
3,4-Methylenedioxymethamphetamine (MDMA or "Ecstasy") is a widely abused, psychoactive recreational drug. There is growing evidence that the MDMA neurotoxic profile may be highly dependent on both its hepatic metabolism and body temperature. Metabolism of MDMA involves N-demethylation to 3,4-methylenedioxyamphetamine (MDA), which is also a drug of abuse. MDMA and MDA are O-demethylenated to...
