Two S-[18F]fluoroalkylated diarylguanidines were synthesized and evaluated in vitro as potential tracers for imaging of N-methyl-d-aspartate receptors (NMDARs) with positron emission tomography (PET). [18F]1 and [18F]10 were synthesized by [18F]fluoroethylation and [18F]fluoromethylation of the thiol precursor 6, respectively. [18F]1 is a promising candidate NMDAR PET tracer, with low nanomolar affinity
两个小号- [ 18 F]氟烷基diarylguanidines合成和体外评价为成像潜在示踪剂Ñ甲基d天冬氨酸受体(NMDAR的)与正电子发射断层扫描(PET)。通过硫醇前体6的[ 18 F]氟乙基化和[ 18 F]氟甲基化分别合成[ 18 F] 1和[ 18 F] 10。[ 18 F] 1是一种有前途的候选NMDAR PET示踪剂,对NMDA PCP部位的纳摩尔亲和力低,选择性高且亲脂性中等。
