Synthesis of ([11C]carbonyl)raclopride and a comparison with ([11C]methyl)raclopride in a monkey PET study

Add time:08/15/2019    Source:sciencedirect.com

IntroductionThe selective dopamine D2 receptor antagonist raclopride is usually labeled with carbon-11 using [11C]methyl iodide or [11C]methyl triflate for use in the quantification of dopamine D2 receptors in human brain. The aim of this work was to label raclopride at the carbonyl position using [11C]carbon monoxide chemistry and to compare ([11C]carbonyl)raclopride with ([11C]methyl)raclopride in non-human primate (NHP) using PET with regard to quantitative outcome measurement, metabolism of the labeled tracers and protein binding.
