Based on currently known PDE5 inhibitors, a series of novel fluorinated compounds bearing a quinoline core have been synthesised via multi-steps reaction pathways. Their affinity for PDE5 and selectivity over other PDE families have been investigated. According to the data collected from this in vitro screening, fluorinated derivatives 24a, b bearing a fluoroethoxy group at the C-3 position of the
全球范围内阿尔茨海默氏病(AD)的发病率不断上升是一个重大的公共卫生问题。当前的治疗仅提供具有明显副作用的姑息药。因此,迫切需要新的有效治疗方案和新颖的早期诊断工具。最近,有大量的临床前证据表明,磷酸二酯酶5(PDE5)作为AD中的生物标志物和药物靶标在临床上均可能相关。在这项研究中,我们打算开发一种新的放射性氟化示踪剂,以使用PET成像可视化大脑中的PDE5。基于目前已知的PDE5抑制剂,已通过多步反应途径合成了一系列带有喹啉核心的新型氟化化合物。已经研究了它们对PDE5的亲和力和对其他PDE家族的选择性。
