  The Synthesis of (S)-5-Fluoro-1-(2-fluorophenyl)-3-(piperidin-3-ylmethoxy)-1H-indazole, a Norepinephrine/Serotonin Reuptake Inhibitor for the Treatment of Fibromyalgia

  摘要：

  Compound 1, a norepinephrine/serotonin reuptake, inhibitor (NSRI) for the treatment of fibromyalgia, has been synthesized in optically pure form in six linear steps and 48% overall yield with no chromatography. This route features a novel and efficient intramolecular cyclization to generate the indazolone core via a diazotization reaction and the preparation of a stable polymorph of the tartaric acid salt as the desired final form. The original synthetic route has been modified to avoid the use of toxic and expensive reagents, thus enabling the preparation of multigram quantities of API for toxicology studies.

  makes it an appealing target for the potential development of new pain drugs. The utility of nonselective Nav blockers is often limited due to adverse cardiovascular and CNS side effects. We sought more selective Nav1.7 blockers with oral activity, improved selectivity, and good druglike properties. The work described herein focused on a series of 3- and 4-substituted indazoles. SAR studies of 3-substituted

  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。
