  Narrow SAR in odorant sensing Orco receptor agonists

  摘要：

  The systematic exploration of a series of triazole-based agonists of the cation channel insect odorant receptor is reported. The structure-activity relationships of independent sections of the molecules are examined. Very small changes to the compound structure were found to exert a large impact on compound activity. Optimal substitutions were combined using a 'mix-and-match' strategy to produce best-in-class compounds that are capable of potently agonizing odorant receptor activity and may form the basis for the identification of a new mode of insect behavior modification.

  clinical phase III drugs, ASP-5854 (dual A2A/A1 AR antagonist) and preladenant (selective A2A AR antagonist), and using the hybrid medicinal strategy, we characterized novel pyridone-substituted triazolopyrimidine scaffolds as dual A2A/A1 AR antagonists. Among them, compound 1a exerted excellent A2A/A1 AR binding affinity (Ki = 5.58/24.2 nM), an antagonistic effect (IC50 = 5.72/25.9 nM), and good metabolic

  缺血性中风是一种复杂的全身性疾病，其特点是发病率、残疾和死亡率高。突触前腺苷 A 2A和 A 1受体的激活改变了从兴奋性毒性到中风的各种脑损伤。因此，发现双重A 2A /A 1腺苷受体（AR）靶向治疗化合物可能是治疗缺血性中风的策略。受两种临床 III 期药物 ASP-5854（双 A 2A /A 1 AR 拮抗剂）和 preladenant（选择性 A 2A AR 拮抗剂）的启发，我们采用混合药物策略，将新型吡啶酮取代的三唑并嘧啶支架表征为双 A 2A/A 1 AR 拮抗剂。其中，化合物1a表现出优异的A 2A /A 1 AR结合亲和力（K i = 5.58/24.2 nM），拮抗作用（IC 50 = 5.72/25.9 nM），在人肝微粒体、大鼠肝微粒体中具有良好的代谢稳定性和狗肝微粒体。重要的是，化合物1a在氧-葡萄糖剥夺/再灌注 (OGD/R) 处理的 HT22 细胞模型中表现出剂量效应关系。这些发现支持开发双

  The synthesis, SAR, and preclinical characterization of a series of substituted 6,7-dihydro[1,2,4]triazolo[4,3]pyrazin-8(5H)-one P2X7 receptor antagonists are described. Optimized leads from this series comprise some of the most potent human P2X7R antagonists reported to date (IC50s<1nM). They also exhibit sufficient potency and oral bioavailability in rat to enable extensive in vivo profiling. Although
