  Radiosynthesis and evaluation of [11C]EMPA as a potential PET tracer for orexin 2 receptors

  摘要：

  EMPA is a selective antagonist of orexin 2 (OX2) receptors. Previous literature with [H-3]-EMPA suggest that it may be used as an imaging agent for OX2 receptors; however, brain penetration is known to be modest. To evaluate the potential of EMPA as a PET radiotracer in non-human primate (as a step to imaging in man), we radiolabeled EMPA with carbon-11. Radiosynthesis of [C-11] N-ethyl-2-(N-(6-methoxypyridin- 3-yl)-2-methylphenylsulfonamido)-N-(pyridin-3-ylmethyl) acetamide ([C-11] EMPA), and evaluation as a potential PET tracer for OX2 receptors is described. Synthesis of an appropriate non-radioactive O-desmethyl precursor was achieved from EMPA with sodium iodide and chlorotrimethylsilane. Selective O-methylation using [C-11] CH3I in the presence of cesium carbonate in DMSO at room temp afforded [C-11] EMPA in 1.5-2.5% yield (non-decay corrected relative to trapped [C-11] CH3I at EOS) with >= 95% chemical and radiochemical purities. The total synthesis time was 34-36 min from EOB. Studies in rodent suggested that uptake in tissue was dominated by nonspecific binding. However, [C-11] EMPA also showed poor uptake in both rats and baboon as measured with PET imaging. (C) 2013 Elsevier Ltd. All rights reserved.
