Aspiring to develop a positron emission tomography (PET) imaging agent for the GluN2B subunits of the N-methyl-d-aspartate receptor (NMDAR), a key therapeutic target for drug development toward several neurological disorders, we synthesized a series of 2,3,4,5-tetrahydro-1H-3-benzazepine and 6,7,8,9-tetrahydro-5H-benzo[7]annulen-7-amine analogues. After in vitro testing via competition binding assay
渴望开发一种正电子发射断层摄影(PET)成像剂用于的GluN2B亚基Ñ甲基d天冬氨酸受体(NMDAR),用于药物开发的朝向几个神经病症的关键的治疗靶,我们合成了一系列的2,3 ,4,5-四氢-1 H -3-苯并ze庚因和6,7,8,9-四氢-5 H-苯并[7] Annulen-7-胺类似物。通过竞争结合测定和放射自显影进行体外测试后,[ 18就对σ1和σ2受体的特异性和选择性而言,F] PF-NB1成为表现最佳的示踪剂,因此被选择用于进一步的体内评估。铜介导的放射性氟化以良好的放射化学收率和较高的摩尔活度完成。在Wistar大鼠中进行了广泛的体内表征,包括PET成像,生物分布,受体占有率和代谢产物研究。[ 18 F] PF-NB1结合对富含GluN2B的前脑区域具有选择性,并且被GluN2B拮抗剂CP-101606特异性阻断,没有剂量依赖性,且没有脑放射性代谢物。[ 18 F] PF-NB1是一种很有前途的氟18
