  Synthesis of spirocyclic σ1 receptor ligands as potential PET radiotracers, structure–affinity relationships and in vitro metabolic stability

  摘要：

  Several 3H-spiro[[2] benzofuran-1,40-piperidines] bearing a p-fluorobenzyl residue at the N-atom and various substituents in position 3 of the benzofuran system were synthesized. The crucial reaction steps are the addition of a lithiated benzaldehyde derivative to the p-fluorobenzylpiperidone 5 and the BF3 center dot OEt2 catalyzed substitution of the methoxy group of 2a by various nucleophiles. Structure-affinity relationship studies revealed that compounds with two protons (2d), a methoxy group (2a), and a cyano group (2e) in position 3 possess subnanomolar sigma(1) affinity (K-i = 0.18 nM, 0.79 nM, 0.86 nM) and high selectivity against the sigma(2) subtype. The metabolites of 2a, 2d, and 2e, which were formed upon incubation with rat liver microsomes, were identified. Additionally, the rate of metabolic degradation of 2a, 2d, and 2e was determined and compared with the degradation rate of the non-fluorinated spirocyclic compound 1. For the synthesis of the potential PET tracers [F-18] 2a and [F-18]2e two different radiosynthetic approaches were followed. (C) 2009 Elsevier Ltd. All rights reserved.

  whereas the spirobenzopyran nitrile 13 with a methylene spacer is 10-fold less potent. Among the reported compounds, 1'-benzyl-3,4-dihydrospiro[[2]benzopyran-1,4'-piperidine]-3-carbonitrile 5 represents the most potent sigma(1) receptor ligand with a K(i) value of 1.54 nM and a sigma(1)/sigma(2) selectivity ratio of 1030.

  The spirocyclicr1 receptor ligand 1 (1'-benzyl-3-(fluoromethyl)-3H-spiro[[2] benzofuran-1,4'-piperidine]) was prepared in four steps starting from methoxy derivative 5. Due to its high sigma(1) affinity (K-i = 0.74 nM) and selectivity against several other relevant targets, 1 was investigated as F-18-labeled PET tracer and its biological properties were compared with those of homologous fluoroalkyl derivatives 2-4. The fluoromethyl derivative 1 was faster metabolized in vitro than homologs 2-4. In contrast to the radiosynthesis of [F-18]2-4, the nucleophilic substitution of the tosylate 15 using the K[F-18]F-K-222-carbonate complex required heating to 150 degrees C in DMSO to achieve high labeling efficiencies. Whereas radiometabolites of [F-18]2-4 were not detected in vivo in the brain of mice, two radiometabolites of [F-18]1 were found. Analysis of ex vivo autoradiography images provided rather low target-to-nontarget ratio for [F-18]1 compared with [F-18]2-4. [F-18]1 showed a fast uptake in the brain, which decreased continuously over time. The brain-to-plasma ratio of the radiotracer [F-18]1 was only exceeded by the fluoroethyl tracer [F-18]2.
