The role of cytochrome P-4502E1 in the neurochemical effects produced by MDMA, by Michel, Robert Earl, Ph.D., Tulane University, 1994, 163 pages;
The drug 3,4-methylenedioxymethamphetamine (MDMA), more commonly known as "Ecstasy", is a synthetic amphetamine analogue that possesses neurotoxic properties in the rat. The neurotoxicity produced by MDMA is characterized by a chronic depletion of serotonin and 5-HIAA, inhibition of tryptophan hydroxylase and the destruction of serotonergic nerve axon terminals in the brain. The mechanism by which MDMA produces this neurotoxicity is unknown. However, a popular theory is that this neurotoxicity is mediated by a metabolite of MDMA and not by the parent compound. Thus, the purpose of this present study was to investigate further the role of metabolism in the mediation of the neurotoxicity produced by MDMA. Since MDMA is metabolized by a family of enzymes known as cytochrome P450, a specific isozyme may be responsible for the formation of a neurotoxic metabolite, or metabolites, from MDMA.
