Studies on the mechanisms underlying amiloride enhancement of 3,4-methylenedioxymethamphetamine-induced serotonin depletion in rats.

European Journal of Pharmacology May 21, 2007 Beatriz Goñi-allo, Elena Puerta, Isabel Hervias et al. 13 citations

Amiloride and several of its congeners known to block the Na(+)/Ca(2+) and/or Na(+)/H(+) antiporters potentiate methamphetamine-induced neurotoxicity without altering methamphetamine-induced hyperthermia. We now examine whether amiloride also exacerbates 3,4-methylenedioxymethamphetamine (MDMA)-induced long-term serotonin (5-HT) loss in rats. Amiloride (2.5 mg/kg, every 2 h x 3, i.p.) given at...

2‐Deoxy‐D‐Glucose Prevents and Nicotinamide Potentiates 3,4‐Methylenedioxymethamphetamine‐Induced Serotonin Neurotoxicity

Journal of Neurochemistry September 1, 2000 Isabel Hervias, Berta Lasheras, Norberto Aguirre

Abstract: Neurotoxicity induced by different substituted amphetamines has been associated with the exhaustion of intracellular energy stores. Accordingly, we examined the influence of 2‐deoxy‐D‐glucose (2‐DG), a competitive inhibitor of glucose uptake and metabolism, and nicotinamide, an agent that improves energy metabolism, on 3,4‐methylenedioxymethamphetamine (MDMA)‐induced...

Serotonergic deficits and impaired passive-avoidance learning in rats by MDEA: a comparison with MDMA.

Pharmacology, biochemistry, and behavior February 2000 M Barrionuevo, N Aguirre, J D Del Río et al.

The serotonergic deficits induced by 3,4-methylenedioxyethamphetamine (MDEA, "eve"), were examined and compared with 3,4 methylenedioxymethamphetamine (MDMA, "ecstasy"). A single dose of MDEA (10, 20, or 40 mg/kg IP) induced a dose-related hyperthermia, but only the highest dose significantly reduced 5-HT content and 5-HT transporter density in the frontal cortex and in the hippocampus 7 days...

α-Lipoic acid prevents 3,4-methylenedioxy-methamphetamine (MDMA)-induced neurotoxicity

Neuroreport November 1, 1999 Norberto Aguirre, Meritxell Barrionuevo, Marı́a J. Ramı́rez et al. 89 citations

A single administration of 3,4-methylenedioxymetham-phetamine (MDMA, 20 mg/kg, i.p.), induced significant hyperthermia in rats and reduced 5-hydroxytryptamine (5-HT) content and [3H]paroxetine-labeled 5-HT transporter density in the frontal cortex, striatum and hippocampus by 40–60% 1 week later. MDMA treatment also increased glial fibrillary acidic protein (GFAP) immunoreactivity in the...
