  二氧三嗪衍生物作为一类新的 P2X3 受体拮抗剂：先导和初步 SAR 研究的确定

  摘要：

  P2X 3受体是一种 ATP 门控离子通道，主要位于外周感觉神经元。目前，正在使用 P2X 3受体拮抗剂治疗慢性疼痛或咳嗽进行多项临床试验。为了鉴定 P2X 3先导化合物，我们重新检查了 HTS 评估化合物并选择了二氧代三嗪衍生物，从中我们鉴定了一种命中化合物。由于命中先导 SAR，我们获得了对 P2X 3受体具有中等抑制作用的先导化合物1 (IC 50 , 128 nM)。这种先导化合物的效力和 PK 曲线的进一步改进最终导致了选定的化合物74（P2X 3 IC50 , 16.1 nM；P2X 2/3 IC 50 , 2931 nM)，在神经性疼痛的大鼠坐骨神经部分结扎模型 (ED 50 , 3.1 mg/kg) 中显示出对口服给药的异常性疼痛有很强的镇痛作用。
