| 1.14.99.1 | additional information | neurotoxicity of the amphetamine analogues methamphetamine and 3,4-methylenedioxyamphetamine, the active metabolite of ecstasy, may involve their prostaglandin H synthase-dependent bioactivation to free radical intermediates that generate reactive oxygen species and oxidatively damage cellular macromolecules. The activation effect is blocked by irreversible enzyme inhibitor acetylsalicylic acid, overview | Homo sapiens |
