nonreentrant initiation of ventricular tachycardia. NCX is an attractive target for treatment in heart failure and myocardial ischemia-reperfusion. We have designed and synthesized a series of phenoxypyridine derivatives, based on compound 3. These derivatives have been evaluated for their inhibitory activity against both the reverse and forward mode of NCX in CCL39 cells. We have discovered several
钠钙交换剂(NCX)被称为控制心肌细胞中Ca(2+)浓度的转运蛋白。在心力衰竭和心肌缺血-再灌注的情况下,NCX是导致心律失常的瞬态内向电流的基础,该电流导致心动过速后的去极化和非折返性延迟。NCX是治疗心力衰竭和心肌缺血-再灌注的有吸引力的靶标。我们基于化合物3设计并合成了一系列苯氧基吡啶衍生物。已评估了这些衍生物对CCL39细胞中NCX反向和正向模式的抑制活性。我们发现了几种新型的有效NCX抑制剂(39q,48k),它们对反向NCX抑制活性具有很高的选择性。
