Synthesis and biological evaluation of 2β,3α-(substituted phenyl)nortropanes as potential norepinephrine transporter imaging agents
摘要:
A series of 2 beta,3 alpha-(substituted phenyl)nortropanes was synthesized and evaluated in vitro for human monoamine transporters. All compounds studied in this series exhibited nanomolar potency for the norepinephrine transporter (NET). Radiolabeling and nonhuman primate microPET brain imaging studies were performed with the most promising compound, [C-11]1, to determine its utility as a NET imaging agent. Despite high in vitro affinity for the human NET, the high uptake of [C-11]1 in the caudate and putamen excludes its use as an in vivo PET imaging agent for the NET. (C) 2007 Elsevier Ltd.

3alpha-(substituted phenyl)nortropane-2beta-carboxylic acid methyl esters (8a-h) showed high affinity for the norepinephrine transporter (NET). The most potent and selectivecompound was 3alpha-(3-fluoro-4-methylphenyl)nortropane-2beta-carboxylic acid methyl ester (8d), with a Ki of 0.43 nM at the NET and 21- and 55-fold selectivity relative to binding at the dopamine and serotonin transporters.
