Synthesis, radiolabeling and in vivo evaluation of [11C](R)-1-[4-[2-(4-methoxyphenyl)phenyl]piperazin-1-yl]-3-(2-pyrazinyloxy)-2-propanol, a potential PET radioligand for the 5-HT7 receptor

novel serotonin 7 (5-HT7) receptor PET radioligand we synthesized and evaluated a new series of biphenylpiperazine derivatives in vitro. Among the studied compounds, (R)-1-[4-[2-(4-methoxyphenyl)phenyl]piperazin-1-yl]-3-(2-pyrazinyloxy)-2-propanol ((R)-16), showed the best combination of affinity, selectivity, and lipophilicity, and was thus chosen for carbon-11 labelling and evaluation in pigs.

在寻找新型的5-羟色胺7(5-HT 7)受体PET放射性配体中,我们合成和评价了一系列的联苯哌嗪衍生物的体外新系列。在研究的化合物中,(R)-1- [4- [2-(4-甲氧基苯基)苯基]哌嗪-1-基] -3-(2-吡嗪基氧基)-2-丙醇((R)-16),显示出亲和力,选择性和亲脂性的最佳组合,因此被选择用于猪的碳11标记和评估。静脉注射后,[ 11 C](R)-16进入猪脑并显示出可逆的示踪动力学。用5-HT 7受体选择性拮抗剂SB-269970进行预处理(1)导致[ 11 C](R)-16结合的有限减少,这表明该放射性配体不是在体内对大脑5-HT 7受体成像的最佳选择,但它可以作为新型化合物的先导化合物5-HT 7受体PET放射性配体。
