  11C-Fallypride: radiosynthesis and preliminary evaluation of a novel dopamine D2/D3 receptor PET radiotracer in non-human primate brain

  摘要：

  Fallypride [benzamide, 5-(3-fluoropropyl)-2,3-dimethoxy-N-[(2S)-1-(2-propenyl)-2-pyrrolidinyl]methyl]-, CAS RN 166173-78-0] is a selective dopamine D2/D3 receptor antagonist. Carbon-11 labeled fallypride may serve as a radiotracer for use in biomedical imaging technique positron emission tomography (PET). The precursor, 5-(3-fluoropropyl)-2-hydroxy-3-metboxy-N-[(2S)-1-(2-propenyl)-2-pyrrolidinyl]methyl]benzamide was synthesized from 2-hydroxy-3-methoxy-5-(2-propenyl)benzoic acid, methyl ester in seven steps with approximately 10% overall chemical yield. Using this precursor C-11-fallypride was produced by radiolabeling with C-11-methyl iodide in 25-40% radiochemical yields with specific activities of 200-1000 Ci/mmol. PET imaging studies in nonhuman primates with C-11-fallypride showed radiotracer localization in dopaminergic brain regions such as caudate, putamen, thalamus and cortex. This regional localization of C-11-fallypride is similar to that observed previously for F-18-fallypride. The results suggest C-11-fallypride is a useful PET radiotracer for imaging dopamine D2/D3 receptors. (C) 2003 Elsevier Ltd. All rights reserved.
