We report the discovery of 6,7-dimethoxy-4-(pyridin-3-yl)cinnolines as novel inhibitors of phosphodiesterase 10A (PDE10A). Systematic examination and analyses of structure–activity-relationships resulted in single digit nM potency against PDE10A. X-ray co-crystal structure revealed the mode of binding in the enzyme’s catalytic domain and the source of selectivity against other PDEs. High in vivo clearance
我们报告发现6,7-二甲氧基-4-(吡啶-3-基)cinnolines作为磷酸二酯酶10A(PDE10A)的新型抑制剂。对结构-活性关系的系统检查和分析导致抗PDE10A的位数为nM。X射线共晶体结构揭示了酶催化结构域中的结合模式以及对其他PDE的选择性来源。借助代谢物鉴定(ID)研究解决了大鼠体内高清除率的问题。这些发现共同产生了化合物39,它是一种有前途的有效PDE10A抑制剂,在大鼠中具有良好的体内代谢稳定性,并在啮齿动物行为模型中具有功效。
