Na v 1.7电压门控离子通道在疼痛信号传导途径中的作用的遗传验证使其成为潜在的新型止痛药开发目标。由于心血管和中枢神经系统的不良反应,非选择性Na v阻滞剂的应用常常受到限制。我们寻求具有口服活性,更高的选择性和良好的药物性质的更具选择性的Na v 1.7阻滞剂。本文所述的工作集中于一系列3-和4-取代的吲唑。3取代的吲唑的SAR研究得到了类似物7,其在体外和体内的活性良好,但在大鼠体内的药代动力学却很差。对4-取代的吲唑的优化产生了两种化合物27和48,具有良好的体外和体内活性,并具有改善的大鼠药代动力学特征。27和48在急性大鼠单碘乙酸盐诱发的骨关节炎模型的疼痛中均显示出强劲的活性,而48的亚慢性给药则显示在7天内向较低的EC 50转移。

The study reports selective electrochemical synthesis of 1H-indazoles and N-oxides, where electrochemical outcomes were dictated by the cathode material (RVC=reticulated vitreous carbon). The adaptability of 1H-indazole N-oxides for various C−H functionalization reactions was showcased. Furthermore, 1H-indazole N-oxides were utilized to synthesize the pharmaceutical molecules lificiguat and YD (3)
