A new series of phenylquinazoline inhibitors of Kv 1.5 is disclosed. The series was optimized for Kv 1.5 potency, selectivity versus hERG, pharmacokinetic exposure, and pharmacodynamic potency. 5-Phenyl-N-(pyridin-2-ylmethyl)-2-(pyrimidin-5-yl)quinazolin-4-amine (13k) was identified as a potent and ion channel selective inhibitor with robust efficacy in the preclinical rat ventricular effective refractory period (VERP) model and the rabbit atrial effective refractory period (AERP) model.
公开了一系列新型Kv 1.5的苯基喹唑啉抑制剂。该系列针对Kv 1.5效力、对hERG的选择性、药代动力学暴露和药效学效力进行了优化。5-苯基-N-(吡啶-2-基甲基)-2-(嘧啶-5-基)喹唑啉-4-胺(13k)被鉴定为一种强效且离子通道选择性抑制剂,在临床前大鼠心室有效不应期(VERP)模型和兔心房有效不应期(AERP)模型中具有强大的疗效。
