calcium-activated, dual substrate phosphodiesterases expressed in both the CNS and periphery that play a role in the integration of intracellular calcium and cyclic nucleotide signaling cascades. Exploration of the potential in targeting this family of enzymes to treat neuropsychiatric disorders has been hampered by a lack of potent, selective, and brain penetrable PDE1 inhibitors. To identify such compounds we used
PDE1是在中枢神经系统和周围区域表达的钙激活双底物磷酸二酯酶家族,在细胞内钙和环状核苷酸信号级联反应的整合中发挥作用。由于缺乏有效,选择性和脑穿透性的PDE1抑制剂,阻碍了针对这种酶家族治疗神经精神疾病的潜力的探索。为了鉴定此类化合物,我们使用了高通量筛选,基于结构的设计和针对性的合成化学,以发现4-氨基喹唑啉7a(PF-04471141)和4-茚满基喹唑啉27(PF-04822163)每种都是易于穿越血脑屏障的PDE1抑制剂。这些基于喹唑啉的PDE1选择性抑制剂代表了有价值的新工具,可用于研究PDE1调节的生物学过程并开始确定此类化合物治疗神经精神疾病的潜在治疗作用。
