The synthesis of N′4-[11C]methyl-ciprofloxacin for pharmacological studies using positron emission tomography is described. The starting material was treated with [11C]methyl iodide at 120°C in DMF for 5 min. After HPLC separation on a C18-column with water/ethanol as mobile phase, the [11C]methyl labelled compound was produced with a radiochemical yield of at least 25% (end of synthesis from [11C]CO2). Activities from 1.48 to 2.22 GBq (40 to 60 mCi) were obtained 1 h after the irradiation, ready for intravenous injection. The carrier ranged between 0.05 and 0.08 μmol (0.010–0.016 μmol/ml).

本文描述了用于药理学研究的N′4-[11C]甲基环丙沙星的合成,使用正电子发射断层扫描(PET)。起始材料在120°C下用[11C]甲基碘处理5分钟,溶剂为DMF。在C18柱上进行HPLC分离,以水/乙醇作为流动相,最终产物的放射化学产率至少为25%(从[11C]CO2合成结束时)。辐射活性在照射后1小时内获得,范围为1.48至2.22 GBq(40至60 mCi),可用于静脉注射。载体量在0.05至0.08 μmol(0.010–0.016 μmol/ml)之间。版权 © 2002 John Wiley & Sons, Ltd.
