A series of 3β-(p-substituted phenyl)tropane-2β-carboxylic acid methyl esters (2) were synthesized and found to possess high affinity for the cocaine binding site in rat striatum. The p-chloro (2c) and p-iodo (2n) compounds, which were the most potent analogues prepared, were found to be 85 and 78 times more potent than (-)-cocaine. The p-bromo (2m) and p-methyl (2d) were also 56 and 60 times more potent than cocaine. QSAR and CoMFA studies were conducted to correlate binding affinity of the cocaine analogues with their structural features. Whereas the QSAR study gave relatively low correlations, the CoMFA study gave a correlation with high predictive value.
Synthesis of 3-arylecgonine analogues as inhibitors of cocaine binding and dopamine uptake

3-Arylecgonine analogues were synthesized and characterized by 1H and 13C NMR, IR, and MS. The compounds were synthesized as racemates from cycloheptatriene-7-carboxylic acid or enantiomerically from (-)-cocaine. These analogues were tested for their ability to inhibit [3H]cocaine binding to bovine striatal tissue and to inhibit [3H]dopamine uptake into striatal synaptosomes. Methyl (1RS-2-exo-3-exo)-8-methyl-3-phenyl-8-azabicyclo[3.2.1]octane-2-carboxylate was the most potent analogue. IC50 values for inhibition of cocaine binding and dopamine uptake were 20 and 100 nM, respectively. The racemates and the 1R isomers were equally potent inhibitors of binding and uptake. Methyl (1RS-2-endo-3-exo)-3-(2,4-dinitrophenyl)-8-methyl-8- azabicyclo[3.2.1]octane-2-carboxylate was the least potent. IC50 for inhibition of both binding and uptake was 40 μM.
