Altropane (O-587, IACFT, 2β-carbomethoxy-3β-(4-fluorophenyl)-N-((E)-3-iodo-prop-2-enyl)tropane) is a phenyltropane derivative which acts as a potent dopamine reuptake inhibitor and long-acting stimulant drug. It has mainly been used as the 125I radiolabelled form for mapping the distribution of dopamine transporters in the brain,[1] and consequently this has led to its development as a potential diagnostic tool for early detection of Parkinson's disease.[2] It is also being investigated for potential use in the diagnosis and treatment of attention deficit hyperactivity disorder (ADHD).[3][4]
