  Discovery and Optimization of 1-(4-(Pyridin-2-yl)benzyl)imidazolidine-2,4-dione Derivatives As a Novel Class of Selective Cannabinoid CB2 Receptor Agonists

  摘要：

  Here, we report the identification and optimization of 1-(4-(pyridin-2-yl)benzyl)imidazolidine-2,4-dione derivatives as a novel chemotype with selective cannabinoid CB2 receptor agonist activity. 1 is a potent and selective cannabinoid CB2 receptor agonist (hCB2 pEC(50) = 8.6). The compound was found to be metabolically unstable, which resulted in low oral bioavailability in rat (F-po = 4%) and possessed off-target activity at the hERG ion channel (pK(i), = 5.5). Systematic modification of physicochemical properties, such as lipophilicity and basicity, was used to optimize the pharmacokinetic profile and hERG affinity of this novel class of cannabinoid CB2 receptor agonists. This led to the identification of 44 as a potent, selective, and orally bioavailable cannabinoid CB2 receptor agonist (hCB2 pEC(50) = 8.0; hERG pK(i) < 4; F-po = 100%), which was active in a rat spinal nerve ligation model of neuropathic pain.

  大麻素CB 2受体激动剂的结构动力学关系研究表明，其对停留时间的取代基特异性亲脂作用

  摘要：

  图形化的抽象图。没有可用的字幕。摘要十年前，引入了药物靶标停留时间模型，该模型描述了配体在其蛋白靶标上的结合动力学的重要性。从那时起，它已成功应用于包括GPCR在内的多种蛋白质靶标，用于开发解离动力学较慢（即较长的靶标停留时间）以提高体内功效或具有较短的停留时间以防止靶标相关侧的先导化合物。效果。迄今为止，该模型尚未用于大麻素CB2受体（CB2R）的新型选择性配体的设计和药理学评估，该选择性配体具有治疗组织损伤和炎性疾病的潜力。在这里，我们研究了理化性质之间的关系，两种不同的信号转导途径中的结合动力学和功能活性，即G蛋白激活和b-arrestin募集。我们合成了24个类似物3-环丙基-1-（4-（6-（（1,1-二氧硫代吗啉代）甲基）-5-氟吡啶-2-基）苄基）咪唑烷-2-，4-二酮（LEI101），以前报道过体内活性和CB2R选择性激动剂，具有不同的碱性和亲脂性。我们发现，由于烷基取代基
