This work reports the synthesis, radiolabelling and in vivo evaluation in NMRI mice of [123I]-(4-fluorophenyl)[1-(3-iodophenethyl)piperidin-4-yl]methanone ([123I]-3-I-CO) as a potential SPECT tracer for the 5-HT2A receptor. The tributylstannylprecursor was synthesized with a 15% overall yield. Radiolabelling was performed using an electrophilic iododestannylation with yields of 85%. Radiochemical purity
这项工作报告了 [123I]-(4-氟苯基)[1-(3-iodophenethyl)piperidin-4-yl]methanone ([123I]-3-I-CO) 在 NMRI 小鼠中的合成、放射性标记和体内评价作为 5-HT2A 受体的潜在 SPECT 示踪剂。三丁基甲锡烷基前体以 15% 的总产率合成。放射性标记是使用亲电碘脱烷基化进行的,产率为 85%。放射化学纯度总是>95%。Log P 被确定为 3.10±0.10。示踪剂在小鼠脑中显示出良好的吸收(注射后 10 分钟时为 6.3±1.3% ID/g 组织,注射后 1 小时时为 2±0.36% ID/g 组织)。这些结果保证了对较大动物的进一步研究,以确定 [123I]-3-I-CO 作为 5-HT2A 示踪剂的适用性。版权所有 © 2007 John Wiley & Sons, Ltd.
