  Evaluation of Spirocyclic 3-(3-Fluoropropyl)-2-benzofurans as σ₁ Receptor Ligands for Neuroimaging with Positron Emission Tomography

  摘要：

  A series of various N-substituted 3-(3-fluoropropyl)-3H-spiro[[2]benzofuran-1,4'-piperidines] (7) has been synthesized. In receptor binding studies, the N-benzyl derivative 7a (WMS-1813) revealed extraordinarily high sigma(1) receptor affinity (K-i = 1.4 nM) and excellent sigma(1)/sigma(2) Selectivity (>600fold). In vitro biotransformation of 7a with rat liver microsomes led to three main metabolites. N-Debenzylation was inhibited by introduction of an N-phenylethyl residue (7g). The PET tracer [F-18]7a was synthesized by nucleophilic substitution of the tosylate 13 with K[F-18]F-K222-carbonate complex. The decay corrected radiochemical yield of [F-18]7a was 35-48% with a radiochemical purity of >99.5% and a specific activity of 150-238 GBq/mu mol. The radiotracer properties were evaluated in female CD-1 mice by organ distribution and ex vivo brain autoradiography. The radiotracer uptake in the brain was fast and sufficient, with values of similar to 4% injected dose per gram. Target specificity of [F-18]7a was validated in blocking studies by preapplication of haloperidol, and significant reduction in the uptake of radioactivity was observed in the brain and peripheral organs expressing sigma(1) receptors.
