  Synthesis and in vivo evaluation of [18F]N-(2-benzofuranylmethyl)-N′-[4-(2-fluoroethoxy)benzyl]piperazine, a novel σ1 receptor PET imaging agent

  摘要：

  N-(2-Benzofuranylmethyl)-N'-[4-(2-fluoroethoxy)benzyl]piperazine (6, sigma(1) K-i = 2.6 nM) was radiolabeled with fluorine-18 to provide a potential sigma(1) receptor radioligand for use in positron emission tomography (PET). Radiofluorination of the appropriate tosylate precursor furnished [F-18]6 with a specific activity of 45 GBq/mu mol, in an average radiochemical yield of 18% and greater than 98% radiochemical purity. MicroPET imaging in Papio hamadryas baboon brain revealed [F-18]6 uptake consistent with sigma receptor distribution, and specificity for sigma receptors was demonstrated in a haloperidol pre-treated animal. [F-18]6 possesses suitable properties for PET imaging of sigma(1) receptors, and further investigation of this sigma(1) receptor tracer is warranted. (C) 2011 Elsevier Ltd. All rights reserved.
