We report the synthesis of compounds structurally related to the high-affinity dopamine D4 receptor ligand N-2-[4-(3-cyanopyridin-2-yl)piperazin-1-yl]ethyl}-3-methoxybenzamide (1e). All compounds were specifically designed as potential PET radioligands for brain D4 receptor visualization, having lipophilicity within a range for brain uptake and weak non-specific binding (0.75100-fold), but its D4
我们报告了与高亲和力多巴胺D4受体配体N- 2- [4-(3-氰基吡啶-2-基)哌嗪-1-基]乙基} -3-甲氧基苯甲酰胺(1e)相关的化合物的合成。所有化合物均经过专门设计,可用于脑D4受体显像的潜在PET放射性配体,具有一定的亲脂性,可吸收脑部,且弱非特异性结合(0.75100倍),但其D4受体亲和力在脑D4受体成像方面次优(Ki = 30 nM)。
