报道了5-羟色胺(5-HT1A)受体显像剂4-[18F]氟-N-[2-[1-(2-甲氧基苯基)-1-哌嗪基乙基]-N-2吡啶基-苯甲酰胺(18F-fluoro-N-[2-[1-(2-methoxyphenyl)]-1-piperazinyl]ethyl-N-2-pridinyl-benzamide
18F-MPPF)的合成和标记。标记前体MPPNO2和各步合成中间体均由红外、元素分析、核磁共振和质谱确证;采用两种加热方法进行氟代亲核置换标记反应。结果显示
微波法标记的放化产额(34%—50%
n=10)明显比油浴加热标记法(8%—24%
n=10)高
反应时间(40—50min)也比油浴加热标记法(70—90min)短
用TLC和HPLC检测放射化学纯度(RCP)均大于95%
可用于临床前研究。
The synthesis and fluoro-radiolabelling of serotonin(5-HT1A) receptor imaging agent 4-18F-fluoro-N-[2-[1-(2-methoxyphenyl)-1-piperazinyl]ethyl-N-2-pridinyl-benzamide
18F-MPPF) was reported . The chemical structure of the nitro- labellng precusor MPPNO2 and all its intermediates were verified by IR
elementary analysis
1HNMR and MS. Nucleophilic substitution of fluororeplacement reaction was proceeded by oil-bath heating or microwave heating methed. Radiochemical yield by microwave heating was higher than oil-bath heating
whereas synthetic time of the former was much more shorter than the latter. Final radiochemical purity was above 95% deter-mined by TLC . Thereby it can be used preclinically.
