The labelling reagent 2-[18F]fluoroethylazide was used in a traceless Staudinger ligation. This reaction was employed to obtain the GABAA receptor binding 6-benzyl-4-oxo-1,4-dihydro-quinoline-3-carboxylic acid (2-[18F]fluoroethyl) amide. The radiotracer was prepared with a non-decay corrected radiochemical yield of 7%, a radiochemical purity >95% and a specific radioactivity of 0.9 GBq/μmol. The compound
标记试剂2- [ 18 F]氟乙基叠氮化物用于无痕Staudinger连接。该反应用于获得结合了6-苄基-4-氧代-1,4-二氢喹啉-3-羧酸(2- [ 18 F]氟乙基)酰胺的GABA A受体。制备的放射性示踪剂的无衰减校正放射化学产率为7%,放射化学纯度> 95%,比放射性为0.9 GBq /μmol。该化合物在正常大鼠中脑渗透率低。还已经制备了一系列对GABA A受体具有纳摩尔至亚纳摩尔亲和力的氟代烷基4-喹诺酮类似物。
