Substituted 1-phenyl-2-cyclopropylmethylamines with high affinity and selectivity for sigma sites
摘要:
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.
A Ru(II) complex mediated synthesis of various N,N-dimethyl and N-monomethyl amines from organic azides using methanol as a methylating agent is reported. This methodology was successfully applied for a one-pot reaction of bromide derivatives and sodium azide in methanol. Notably, by controlling the reaction time several N-monomethylated and N,N-dimethylated amines were synthesized selectively. The

4-(1-Adamantyl)-1-aminobutan-3-one hydrochlorides were synthesized by the Mannich reaction of (1-adamantyl)acetone with paraformaldehyde and secondary amine hydrochlorides (diethylamine, dibenzylamine, piperidine). Analogous reactions of I-adamantyl(methyl)amine with acetone, p-hydroxyacetophenone, and methyl 2-thienyl ketone gave 1-[(1-adamantyl)methylamino]propan-3-one hydrochlorides.
