Diastereoisomeric compounds [(18)F]cis- and [(18)F]trans-4-methylbenzyl 4-[(pyrimidin-2-ylamino)methyl]-3-fluoro-piperidine-1-carboxylates were successfully synthesized as new subtype-selective PET radiotracers for imaging the NR2B subunit containing NMDA receptors. Rat brain section autoradiographies demonstrated a high specific binding in NR2B/NMDA receptor rich regions for both radioligands. The measured logD(7.4) values as well as B(max)/K(d) ratios indicated that both radiotracers possess the adequate properties required for PET radiotracers.
[(18)F]顺式和[(18)F]反式 4-甲基苄基 4-[(嘧啶-2-基氨基)甲基]-3-氟-1-哌啶羧酸酯作为新型亚型选择性 PET 放射性配体,成功合成用于成像含有 NR2B 亚基的 NMDA 受体。大鼠脑切片放射自显影显示两种放射性配体在 NR2B/NMDA 受体丰富的区域均具有高特异性结合。测量的 logD(7.4)值和 B(max)/K(d)比值表明,两种放射性示踪剂均具有 PET 放射性示踪剂所需的适当特性。
