Dopamine transporter (DAT) inhibitors alleviate specific parkinsonian deficits in monkeys: association with DAT occupancy in vivo.
Viable dopamine neurons in Parkinson's disease express the dopamine transporter (DAT) and release dopamine (DA). We postulated that potent DAT inhibitors, with low affinity for the serotonin transporter (SERT), may elevate endogenously released extracellular dopamine levels to provide therapeutic benefit. The therapeutic potential of eight DAT inhibitors was investigated in 1-methyl-4-phenyl-1,...
متن کاملTo scan or not to scan: DaT is the question.
Neurology 2012;78:688–689 The Food and Drug Administration (FDA) recently approved [I]ioflupane ([I]-fluoropropyl CIT), a dopamine transporter (DAT) radioligand, for SPECT to “assist in the evaluation of adult patients with suspected parkinsonian syndromes (PS).”1 This permits physicians to prescribe [I]ioflupane SPECT scans as part of clinical practice. Advertisements encourage clinicians to o...
متن کاملDopamine reuptake transporter (DAT) "inverse agonism"--a novel hypothesis to explain the enigmatic pharmacology of cocaine.
The long held view is cocaine's pharmacological effects are mediated by monoamine reuptake inhibition. However, drugs with rapid brain penetration like sibutramine, bupropion, mazindol and tesofensine, which are equal to or more potent than cocaine as dopamine reuptake inhibitors, produce no discernable subjective effects such as drug "highs" or euphoria in drug-experienced human volunteers. Mo...
متن کاملDopamine D1, D2, D3 Receptors, Vesicular Monoamine Transporter Type-2 (VMAT2) and Dopamine Transporter (DAT) Densities in Aged Human Brain
The dopamine D(1), D(2), D(3) receptors, vesicular monoamine transporter type-2 (VMAT2), and dopamine transporter (DAT) densities were measured in 11 aged human brains (aged 77-107.8, mean: 91 years) by quantitative autoradiography. The density of D(1) receptors, VMAT2, and DAT was measured using [(3)H]SCH23390, [(3)H]dihydrotetrabenazine, and [(3)H]WIN35428, respectively. The density of D(2) a...
متن کاملImpact of Dopamine Transporter Scan in Parkinson’s Disease
1.1 Technique of nigrostriatal FP-CIT SPECT The density of the presynaptic dopamine reuptake transporters (DAT) can be quantified with [123I]FP-CIT SPECT. The tracer Fluorpropyl-Carbomethoxy-Iodophenyl-Tropan (FPCIT), marked by radioactive 123iodine [123I] (therefore the name [123I]FP-CIT), binds reversibly to the DAT on the presynaptic membrane. Before application of FP-CIT, the iodine uptake ...
