Selective ligands for either sigma1 (σ1) or σ2 binding sites are potentially useful for gaining a better understanding of the physiological functions of these proteins. Moreover, potent and selective homochiral σ1/su

A series of 1-phenyl-2-cyclopropylmethylamines structurally related to (+)- and (-)-MPCB were synthesized and their binding affinities for σ1, σ2, opioid and dopamine (D2) receptors were evaluated. Substitution of the cis-N-normetazocine with different aminic moieties provided compounds with high affinity and selectivity for σ binding sites with respect to opioid and dopamine (D2) receptors. The observed increase in σ2 affinity as compared to the parent (+)-MPCB, supports the idea that the particular stereochemistry of (+)-cis-N-normetazocine affects σ1 selectivity but does not affect σ1 affinity. The (±)-cis isomers of methyl 2-[(1-adamantylamino)methyl]-1-phenylcyclopropane-1-carboxylate (18) displayed a higher affinity and selectivity for the σ1 and σ2 receptor subtypes compared to the (±)-trans 19. Interestingly, the enantiomer (-)-cis 18 displayed a preference for σ1 receptor subtype whereas the (+)-cis 18 did for σ2. These results prompt us to synthesize compounds with modification of nitrogen and carboxyl groups. The compounds obtained showed high affinities and selectivity for σ 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 4.05nM for σ1 and σ2 binding sites, respectively. Copyright (C) 2000 Elsevier Science Ltd.
