摘要:
A series of front bridged tricyclic 3 beta-(4'-halo or 4'-methyl)phenyltropanes bearing methylene or carbomethoxymethylene on the bridge to the 2 beta-position was synthesized, and their binding affinities were deter-mined in cells transfected to express human norepinephrine transporter (NET), serotonin transporter (SERT), and dopamine transporter (DAT) via competition binding assays. All compounds studied in this series exhibit a moderate to high potency at all three transporters with SERT or DAT selectivity. 3 beta-(4'-iodo)phenyltropane bearing methylene on the bridge to the 2 beta-position (24) presents a particularly attractive pharmacological profile, with very high SERT affinity (K-i = 0.09 nM) and selectivity versus NET (65-fold) and DAT (94-fold).
