A series of potent thienotriazolopyrimidinone-based PDE1 inhibitors was discovered. X-ray crystal structures of example compounds from this series in complex with the catalytic domain of PDE1B and PDE10A were determined, allowing optimization of PDE1B potency and PDE selectivity. Reduction of hERG affinity led to greater than a 3000-fold selectivity for PDE1B over hERG. 6-(4-Methoxybenzyl)-9-((tet
发现了一系列基于硫杂三氮杂吡喃二酮的有效PDE1抑制剂。确定了该系列示例化合物与PDE1B和PDE10A催化结构域复合的X射线晶体结构,从而优化了PDE1B的效力和PDE的选择性。hERG亲和力的降低导致对PDE1B的选择性是hERG的3000倍以上。6-(4-甲氧基苄基)-9-(((四氢-2 H-吡喃-4-基)甲基)-8,9,10,11-四氢吡啶基[4',3':4,5]噻吩并[3, 2- e ] [1,2,4]三唑并[1,5- c ]嘧啶-5(6 H)-1被确定为口服生物可利用的且可穿透脑的PDE1B酶抑制剂,在大鼠模型中具有有效的记忆增强作用对象识别存储器。
