title: Synthesis and dopamine transporter affinity of chiral 1-[2-[bis(4-fluorophenyl)methoxy]ethyl]-4-(2-hydroxypropyl)piperazines as potential cocaine abuse therapeutic agents.
abstract: A series of optically pure phenyl-and non-phenyl-substituted 1-[2-[bis(4-fluorophenyl)methoxy]ethyl]-4-(2-hydroxypropyl)piperazines was synthesized and their binding affinity for dopamine transporter (DAT) was investigated. The analogues with a hydroxyl group in the S configuration were more selective for the DAT over the serotonin transporter (SERT) than the corresponding R enantiomers. Compound (+)-11 showed high affinity and selectivity for DAT over the SERT and, therefore, is a potential candidate for the development of a long-acting cocaine abuse therapeutic agent.
