  Synthesis of (+)- and (−)-cis-2-[(1-adamantylamino)-methyl]-1-phenylcyclopropane derivatives as high affinity probes for σ1 and σ2 binding sites

  摘要：

  Selective ligands for either sigma(1) (sigma(1)) or sigma(2) binding sites are potentially useful for gaining a better understanding of the physiological functions of these proteins. Moreover, potent and selective homochiral sigma(1) and sigma(2) binding site ligands represent leads to potential radioligands for tumour imaging with positron emission tomography (PET). On the basis of their structural similarity to previous leads, new (+)- and (-)-cis-2-[(1-adamantylamino)-methyl]-1-phenylcyclopropane derivatives were synthesised and their binding affinities for sigma(1) and sigma(2) binding sites were determined. Each enantiomer showed high affinity for both sigma(1) and sigma(2) binding sites, but only (-)-cis-methyl-2-{[1-adamantyl(methyl)amino]methyl}-1-phenylcyclopropane-carboxylate, (-)-4, showed appreciable selectivity for binding to sigma(1) versus sigma(2) sites. The enantiomers of cis-(2-{[1-adamantyl(methyl)amino]methyl}-1-phenylcyclopropyl)methanol, 6, expressed the highest affinity for sigma(1) and sigma(2) binding sites. Ligands (-)-4, (+)-6 and (-)-6 might be rapidly labelled in their N-methyl groups by methylation of the N-desmethyl analogues with [C-11]iodomethane to provide prospective radioligands for PET. The N-desmethyl analogues, which are also high affinity ligands, were prepared and shown to undergo satisfactory methylation with iodomethane. (C) 2002 Elsevier Science S.A. All rights reserved.

  Synthesis and pharmacological evaluation of potent and enantioselective σ1 and σ2 ligands

  摘要：

  In a previous study we found that substitutions of the (+)-cis-N-normetazocine nucleus of (+)-MPCB with 1-adamantanamine provide the compound (+/-)-10 with high affinity and selectivity for sigma receptors. Starting with this result we have synthesized a new series of eight 1-phenyl-2-cyclopropylmethylamines structurally related to (+/-)-10, and binding affinities, with respect to sigma(1), sigma(2), opioid and dopaminergic D-2 receptors, have been reported. All compounds showed a negligible opioid and dopaminergic affinity and high selectivity for sigma receptors. Modifications on the amino moiety and methylcarboxyester group of 10 provide compounds with different sigma(1), and sigma(2) binding affinity and selectivity. Moreover, we have also synthesized the respective enantiomers of componds (+/-)-10 and (+/-)-18 in order to evaluate the enantioselectivity for sigma(1) and sigma(2) receptors. The binding data showed that carboxymethylester on the cyclopropane ring was more critical for enantioselectivity than the hydroxymethylenic group. In fact, the (-)-10 enantionter showed a preference for sigma(1) whereas (+)-10 showed a preference for sigma(2), (C) 2001 Elsevier Science S.A. All rights reserved.

  A series of 1-phenyl-2-cyclopropylmethylamines structurally related to (+)- and (-)-MPCB were synthesized and their binding affinities for or, oz, opioid and dopamine (D-2) receptors were evaluated. Substitution of the cis-N-normetazocine with different aminic moieties provided compounds with high affinity and selectivity for sigma binding sites with respect to opioid and dopamine (D2) receptors. The observed increase in sigma(2) affinity as compared to the parent(+)-MPCB, supports the idea that the particular stereochemistry of (+)-cis-N-normetazocine affects sigma(1) selectivity but does not affect ol affinity. The (+/-)-cis isomers of methyl 2-[(1-adamantylamino)methyl]-1-phenylcyclopropane-1-carboxylate (18) displayed a higher affinity and selectivity for the ol and sigma(2) receptor subtypes compared to the (+/-)-trans 19. interestingly, the enantiomer (-)-cis 18 displayed a preference for ol receptor subtype whereas the (+)-cis 18 did for sigma(2). These results prompt us to synthesize compounds with modification of nitrogen and carboxyl groups. The compounds obtained showed high affinities and selectivity for sigma sites. Moreover, modifications of carboxyl groups provided compounds with the highest affinities in the series. In particular, compound 25 with reverse-type ester showed a K-i of 0.6 and 4.05 nM for sigma(1) and sigma(2) binding sites, respectively. (C) 2000 Elsevier Science Ltd. All rights reserved.
