Following the discovery of small molecule acyl piperazine ROMK inhibitors, the acyl octahydropyrazino[2,1-c][1,4]oxazine series was identified. This series displays improved ROMK/hERG selectivity, and as a consequence, the resulting ROMK inhibitors do not evoke QTc prolongation in an in vivo cardiovascular dog model. Further efforts in this series led to the discovery of analogs with improved pharmacokinetic
发现小分子酰基哌嗪ROMK抑制剂后,鉴定了酰基八氢吡嗪并[2,1-c] [1,4]恶嗪系列。该系列显示出改进的ROMK / hERG选择性,因此,所得的ROMK抑制剂在体内心血管狗模型中不会引起QTc延长。在该系列中的进一步努力导致发现了具有改善的药代动力学特征的类似物。与以前的潜在客户相比,该新系列还保留了相当的ROMK效能。
