  • Rapid preparation of [11C]flumazenil: captive solvent synthesis combined with purification by analytical sized columns
    作者:Marcel C. Cleij、John C. Clark、Jean-Claude Baron、Franklin I. Aigbirhio
    DOI:10.1002/jlcr.1152
    日期:——
    To produce the radioligand [N-methyl-11C]flumazenil at very high specific radioactivity for our small animal imaging studies we have developed procedures for its rapid synthesis, purification and analysis. We have developed ‘micro-reactor’ apparatus which are assembled from analytical HPLC guard columns packed with stainless steel powder for performing the carbon-11 methylation reactions. These highly efficient reaction columns enable high radiochemical yields to be obtained with very small amounts of precursor (20–40 µg). The very small amount of reactants used enables the use of small analytical-sized HPLC columns for the rapid purification of the radioligand. Combining these techniques has enabled us to consistently prepare [N-methyl-11C]flumazenil from [11C]iodomethane with radiochemical yields of 80% (decay corrected). This results in 8–10 GBq of [N-methyl-11C]flumazenil at very high specific radioactivities of 520–600 GBq/µmol at the end-of-synthesis. The total preparation time from end-of-bombardment of cyclotron-produced [11C]carbon dioxide to end-of-synthesis is 20 min. A quality control method based on very rapid HPLC analysis (completed within 2 min) on a micro-analytical HPLC column has also being developed to reduce the time from the end-of-synthesis to injection for imaging.

    为了在我们的动物成像研究中制备高比活度的放射性配体[N-甲基-11C]氟马西尼,我们开发了快速合成、纯化和分析的方法。我们开发了由填充不锈钢粉末的分析型HPLC保护柱组装而成的“微反应器”设备,用于进行碳-11甲基化反应。这些高效的反应柱能够在非常少量的前体物质(20-40微克)下获得高的放射化学产率。使用非常少量的反应物使得可以采用小型的分析尺寸HPLC柱进行放射性配体的快速纯化。结合这些技术,我们能够从[11C]碘甲烷一致性地制备[N-甲基-11C]氟马西尼,放射化学产率达到80%(衰变校正)。这结果在合成结束时获得8-10 GBq的[N-甲基-11C]氟马西尼,比活度高达520-600 GBq/微摩尔。从回旋加速器产生的[11C]二氧化碳轰击结束到合成结束的总制备时间为20分钟。我们还开发了一种基于微型分析HPLC柱的快速HPLC分析(在2分钟内完成)的质量控制方法,以减少从合成结束到成像注射的时间。版权所有 © 2007 John Wiley & Sons, Ltd.
  • The use of tetrabutylammonium fluoride to promote<i>N</i>- and<i>O</i>-<sup>11</sup>C-methylation reactions with iodo[<sup>11</sup>C]methane in dimethyl sulfoxide
    作者:Tatsuya Kikuchi、Katsuyuki Minegishi、Hiroki Hashimoto、Ming-Rong Zhang、Koichi Kato

    The N- or O-methylation reactions of compounds bearing amide, aniline, or phenol moieties using iodo[11C]methane (1) with the aid of a base are frequently applied to the preparation of 11C-labeled radiopharmaceuticals. Although sodium hydride and alkaline metal hydroxides are commonly employed as bases in these reactions, their poor solubility properties in organic solvents and hydrolytic activities have sometimes limited their application and made the associated 11C-methylation reactions difficult. In contrast to these bases, tetrabutylammonium fluoride (TBAF) is moderately basic, highly soluble in organic solvents, and weakly nucleophilic. Although it was envisaged that TBAF could be used as the preferred base for 11C-methylation reactions using 1, studies concerning the use of TBAF to promote 11C-methylation reactions are scarce. Herein, we have evaluated the efficiency of the 11C-methylation reactions of 13 model compounds using TBAF and 1. In most cases, the N-11C-methylations were efficiently promoted by TBAF in dimethyl sulfoxide at ambient temperature, whereas the O-11C-methylations required heating in some cases. Comparison studies revealed that the efficiencies of the 11C-methylation reactions with TBAF were comparable or sometimes greater than those conducted with sodium hydride. Based on these results, TBAF should be considered as the preferred base for 11C-methylation reactions using 1.
    含有酰胺、苯胺或酚基团的化合物在碘[11C]甲烷(1)作用下,借助碱进行的N-或O-甲基化反应通常用于制备11C标记的放射药物。尽管氢化钠和碱金属氢氧化物在这些反应中常被用作碱,但它们在有机溶剂中的溶解性差以及水解活性,有时限制了其应用,使得相关的11C-甲基化反应变得困难。与这些碱相比,四丁基氟铵(TBAF)具有适中的碱性,高度溶于有机溶剂,并且亲核性较弱。尽管有预想TBAF可以作为11C-甲基化反应的优选碱,但关于TBAF促进11C-甲基化反应的研究却很少。在此,我们评估了使用TBAF和1对13个模型化合物进行11C-甲基化反应的效率。在大多数情况下,TBAF在室温下能有效促进二甲基亚硫酰胺中的N-11C-甲基化,而在某些情况下O-11C-甲基化则需要加热。比较研究表明,使用TBAF进行的11C-甲基化反应的效率可比或有时大于使用氢化钠的反应。基于这些结果,TBAF应被视为使用1进行11C-甲基化反应的优选碱。
