  Development of an Efficient Synthesis of Two CRF Antagonists for the Treatment of Neurological Disorders

  摘要：

  BMS-764459 (1) and BMS-763534 (2) are CRF1 antagonists for the treatment of neurological disorders such as depression and anxiety. An efficient synthesis of 1 and 2 is described, which features an efficient palladium-catalyzed cyanation of a 5-chloropyrazinone where zinc acetate suppresses dehalogenation. This synthesis was applied to the preparation of > 5 kg of 1 and 2 for clinical studies.

  6-(difluoromethoxy)-2,5-dimethylpyridin-3-amine group in 19e contributed to the potency and improved in vivo properties of this compound and related analogues. 19e had excellent pharmacokinetic properties in rats and dogs and showed efficacy in the defensive withdrawal model of anxiety in rats. The lowest efficacious dose was 1.8 mg/kg. The results of a two-week rat safety study with 19e indicated that this compound

  详细的代谢表征8是一种较早的基于吡嗪酮的铅促肾上腺皮质激素释放因子1（CRF 1）受体拮抗剂，表明该化合物形成了显着水平的反应性代谢产物，如体内和体外生物转化研究所测。由于有大量证据表明反应性代谢物可能与特异药物反应有关，因此这一点特别令人关注。基于吡嗪酮的CRF 1受体拮抗剂的结构活性关系和体内性质的进一步优化以及评估反应性代谢产物形成的研究导致了19e（一种高亲和力的CRF 1受体拮抗剂）的发现（IC 50＝ 0.86nM），其中GSH加合物估计仅为通过胆汁和尿液排泄的药物相关物质总量的0.1％，表明体内反应性代谢物形成的水平较低。19e中一个新的6-（二氟甲氧基）-2,5-二甲基吡啶-3-胺基团对该化合物和相关类似物的效力和体内特性作出了贡献。19e在大鼠和狗中具有出色的药代动力学特性，并且在大鼠焦虑性戒断模型中显示出功效。最低有效剂量为1.8 mg / kg。为期两周的19e大鼠安

  Evidence suggests that corticotropin-releasing factor-1 (CRF1) receptor antagonists may offer therapeutic potential for the treatment of diseases associated with elevated levels of CRF such as anxiety and depression. A pyrazinone-based chemotype of CRF1 receptor antagonists was discovered. Structure−activity relationship studies led to the identification of numerous potent analogues including 12p,
