With the aim of developing fluorinated benzamides that may be useful as radioligands for positron emission tomography, fluorine analogs of eticlopride, in which the N-ethyl group was replaced by 2-fluoroethyl, 3-fluoropropyl and p-fluorobenzyl groups, were synthesized. These derivatives were tested for their ability to displace [3H]spiperone from its specific dopamine D-2 receptor. Their potencies were decreased when compared with eticlopride, but the two fluoroalkylated analogs were in the same order of magnitude as that of haloperidol.
为了开发可用作正电子发射断层扫描放射配体的含氟苯甲酰胺,我们合成了依替氯必利的含氟类似物,其中的 N-乙基被 2-氟乙基、3-氟丙基和对氟苄基取代。测试了这些衍生物将[3H]spiperone 从其特定的多巴胺 D-2 受体中置换出来的能力。与依替氯必利相比,它们的药效有所降低,但这两种氟烷基化类似物与氟哌啶醇的药效处于同一数量级。
