Alpha-Methyldopamine
α-Methyldopamine (α-Me-DA), also known as 3,4-dihydroxyamphetamine (3,4-DHA or HHA), is a research chemical of the catecholamine and substituted amphetamine, amphetamine chemical classes. Its bis-glutathione, glutathionyl metabolite is slightly neurotoxic when directly Intracerebroventricular injection, injected into the brain's ventricles. Interest lies in the fact that 3,4-Methylenedioxyamphetamine, MDA and MDMA may not themselves be responsible for their neurotoxicity, as an intracerebroventricular injection does not appear to cause neurotoxicity. While many studies suggest excitotoxicity or oxidative stress as likely mechanisms, which may be an effect of MDMA itself, this has led to the search for other mechanisms for the observed toxicity of serotonin axons and subsequent reduction in 5-HT (serotonin) and 5-HIAA (its major metabolite in the body) in vivo following administration. A common theory follows that a metabolite in the periphery must be responsible, and several ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
