5-a]pyrimidine PDE2a inhibitors is reported. The design and improvement of the binding properties of this series was achieved using X-ray crystal structures in conjunction with careful analysis of electronic and structural requirements for the PDE2a enzyme. One of the lead compounds, compound 27 (DNS-8254), was identified as a potent and highly selective PDE2a enzyme inhibitor with favorable rat pharmacokinetic
报道了一系列有效的和选择性的[1,2,4]三唑[1,5- a ]嘧啶PDE2a抑制剂。使用X射线晶体结构并仔细分析PDE2a酶的电子和结构要求,可以设计和改进该系列的结合性能。一种主要化合物,化合物27(DNS-8254)被确定为一种有效且高选择性的PDE2a酶抑制剂,具有良好的大鼠药代动力学特性。有趣的是,与PDE2a活性位点中存在的Tyr827的氧形成卤素键,促进了化合物27效力的提高。体内化合物27在新型物体识别的大鼠模型中显示出显着的记忆增强作用。综上所述,这些数据表明化合物27可能是探索选择性PDE2a抑制作用的药理学的有用工具。
