Synthesis and monoamine uptake inhibition of conformationally constrained 2β-carbomethoxy-3β-phenyl tropanes

A series of 2β-carbomethoxy-3β-phenyl tropanes with conformationally constrained nitrogen substituents were synthesized as potential selective dopamine transporter ligands. These novel compounds were examined for their monoamine uptake inhibition potency at the human dopamine transporter (hDAT), the human serotonin transporter (hSERT) and the human noradrenalin transporter (hNET), stably expressed in human embryonic kidney cells (HEK). A SAR-study was conducted to determine the contribution of extended, 4-fluorinated, conformationally constrained C4 chains at the tropane nitrogen to human monoamine transporter affinity and selectivity.

Fluoralkenyl nortropanes

Provided are compounds of the following formula: wherein R is C2-C6 mono- or multi-unsaturated hydrocarbon having one or more ethylene, acetylene or allene groups, A is 18 or 19, and X is H or halogen. The compounds of the invention bind to dopamine transporter with high affinity and selectivity and are thus useful as diagnostic and therapeutic agents for diseases associated with dopamine transporter dysfunction. The radiolabeled compounds are useful as imaging agents for visualizing the location and density of dopamine transporter by PET imaging.

Secondary amine analogues of 3 beta-(4'-substituted phenyl)tropane-2 beta-carboxylic acid esters and N-norcocaine exhibit enhanced affinity for serotonin and norepinephrine transporters.

N-Norcocaine (2) and six N-nor-3 beta-(4'-substituted phenyl)tropane-2 beta-carboxylic acid esters (4a-f) were synthesized by N-demethylation of cocaine (1) and the appropriate 3 beta-(substituted phenyl)-tropane analogues (3a-f) with alpha-chloroethyl chloroformate. Radioligand binding affinities of 2 and 4a-f at the DA, 5-HT, and NE transporter were measured and compared to those of 1 and 3a-f. N-Demethylation produced relatively small effects at the DA transporter. In contrast, 4-19-fold and 2-44-fold enhanced affinity at the serotonin and norepinephrine transporter resulted from demethylation. N-Nor-3 beta-(4'-iodophenyl)tropane-2 beta-carboxylic acid methyl ester (4d) with an IC50 = 0.36 nM showed the greatest affinity for the serotonin transporter. However, N-nor-3 beta-(4'-ethylphenyl)tropane-2 beta-carboxylic acid methyl ester (4e) showed the greatest selectivity for the serotonin transporter.
