As part of our program to develop PET tracers for investigating monoaminergic processes in the brain, mianserin, a tetracyclic, atypical antidepressant, was selected as a candidate for labelling with 11C for in vivo evaluation. [N-methyl-11C]Mianserin was produced by the alkylation of N-desmethyl mianserin with [11C]methyl iodide followed by HPLC purification and formulation. [N-methyl-11C]Mianserin was obtained with a radiochemical purity >93% in a 16% decay corrected radiochemical yield. For a typical production starting with 40 GBq [11C]CO2, 1.9 GBq [N-methyl-11C]mianserin was obtained as a formulated solution in a synthesis time of 35 min (counted from EOB).

作为我们开发正电子发射断层扫描(PET)示踪剂以研究大脑单胺能过程的项目的一部分,选择了四环类非典型抗抑郁药米安色林作为与11C标记的候选物,以进行体内评估。[N-甲基-11C]米安色林是通过用[11C]甲基碘对N-去甲基米安色林进行烷基化反应后,再通过高效液相色谱(HPLC)纯化和制剂制备得到的。[N-甲基-11C]米安色林的放射化学纯度超过93%,经衰变校正后的放射化学产率为16%。以40 GBq [11C]CO2为起始材料的典型生产中,得到1.9 GBq的[N-甲基-11C]米安色林,作为制剂溶液,合成时间为35分钟(从反应结束开始计时)。版权所有 © 2001 John Wiley & Sons, Ltd.
