  Novel Vanilloid Receptor-1 Antagonists:  3. The Identification of a Second-Generation Clinical Candidate with Improved Physicochemical and Pharmacokinetic Properties

  摘要：

  Based on the previously reported clinical candidate, AMG 517 (compound 1), a series of related piperazinylpyrimidine analogues were synthesized and evaluated as antagonists of the vanilloid 1 receptor (VR1 or TRPV1). Optimization of in vitro potency and physicochemical and pharmacokinetic properties led to the discovery of (R)-N-(4-(6-(4-(1-(4-fluorophenyl)ethyl)piperazin-1-yl)pyrimidin-4-yloxy)benzo[d]thiazol-2-yl)acetamide (16p), a potent TRPV1 antagonist [rTRPV1(CAP) IC50 = 3.7 nM] with excellent aqueous solubility (>= 200 mu g/mL in 0.01 N HCl) and a reduced half-life (rat t(1/2) = 3.8 h, dog t(1/2) = 2.7 h, monkey t(1/2) = 3.2 h) as compared to AMG 517. In addition, compound 16p was shown to be efficacious at blocking a TRPV1-mediated physiological response in vivo (ED50 = 1.9 mg/kg, p.o. in the capsaicin-induced flinch model in rats) and was also effective at reducing thermal hyperalgesia induced by complete Freund's adjuvant in rats (MED = 1 mg/kg, p.o). Based on its improved overall profile, compound 16p (AMG 628) was selected as a second-generation candidate for further evaluation in human clinical trials as a potential new treatment for chronic pain.

  用苯并噻唑片段分子探测蛋白激酶DYRK1A的ATP结合口袋

  摘要：

  DYRK1A已成为使用小分子疗法治疗阿尔茨海默氏病的潜在靶标。上的由萤火虫观察选择性抑制DYRK1A的基础d-荧光素，我们已经使用X射线晶体学和NMR技术探索了DYRK1A的苯并噻唑支架片段大小变异体的静态和动态结构特性。这些化合物具有出色的配体效率，并在动态平衡中显示出显着的结合模式多样性。结合的几何形状部分取决于通常被认为是“弱”的相互作用，包括以“ F-CO”，“硫-芳族”和“卤素-芳族”相互作用为代表的“正交多极”类型，以及通过改变氢键而调节的氢键。吸电子基团。这些研究表明，苯并噻唑支架对于治疗性DYRK1A抑制剂的开发具有很高的前景。此外，绑定互动的微妙之处包括动力学，

  Small molecule TRPV1 antagonists have been a recent focus in the search for pain treatment agents. We herein describe a practical and scalable synthesis of AMG 628 (1), a bis-substituted pyrimidine derivative that was identified as a highly efficacious agent, suitable for clinical development. Highlights of our approach include a practical route to a substituted benzothiazole, a scalable synthesis of an enantiopure piperazine fragment, and identification of conditions for selective coupling reactions on 2,6-dichloropyrimidine, to access the active pharmaceutical ingredient in high purity and overall yield.
