  Identification of a highly potent and selective CB2 agonist, RQ-00202730, for the treatment of irritable bowel syndrome

  摘要：

  Herein we report the identification of a highly potent and selective CB2 agonist, RQ-00202730 (40), obtained by lead optimization of the benzimidazole scaffold. Compound 40 showed strong agonistic activity with an EC50 of 19 nM and excellent selectivity (>1300-fold) over the CB1 receptor. Compound 40 displayed a dose dependent analgesic effect on TNBS-induced visceral hypersensitivity in rats by oral administration (ED50 0.66 mg/kg at 2.5 h after oral administration). In addition, 40 did not show a significant effect on body temperature in rats after oral administration at 300 mg/kg. These findings suggest that highly selective CB2 agonists will be effective agents for IBS therapy. (C) 2014 Elsevier Ltd. All rights reserved.

  Optimisation of a novel series of selective CNS penetrant CB2 agonists

  摘要：

  A series of benzimidazole CB2 receptor agonists were prepared and their properties investigated. Optimisation of the three benzimidazole substituents led to the identification of compound 23, a potent CB2 full agonist (EC50 2.7 nM) with excellent selectivity over the CB1 receptor (> 3000-fold). Compound 23 demonstrated good CNS penetration in rat. Further optimisation led to the identification of compound 34 with improved selectivity over hERG and excellent CNS penetration in rat.

  compound bound to the CREB binding protein (CBP) and the first bromodomain of BRD4 (BRD4(1)) were used to guide the design of more selective compounds. The crystal structures obtained revealed two distinct binding modes. By varying the aryl substitution pattern and developing conformationally constrained analogues, selectivity for CBP over BRD4(1) was increased. The optimized compound is highly potent (Kd

  缺乏针对溴结构域和末端外 (BET) 亚家族之外的溴结构域的小分子抑制剂。在这里，我们描述了人类赖氨酸乙酰转移酶 CBP/p300 溴结构域模块的高效和选择性配体，由一系列 5-异恶唑基苯并咪唑开发而成。我们的出发点是片段命中，使用 Suzuki 偶联、苯并咪唑形成反应和还原胺化的平行合成将其优化为更有效和选择性更强的先导化合物。使用热稳定性测定法研究了先导化合物对其他溴结构域家族成员的选择性，结果显示对结构相关的 BET 家族成员有一些抑制作用。为了解决 BET 选择性问题，与 CREB ​​结合蛋白 (CBP) 和 BRD4 的第一个溴结构域 (BRD4(1)) 结合的先导化合物的 X 射线晶体结构用于指导更具选择性的化合物的设计。获得的晶体结构揭示了两种不同的结合模式。通过改变芳基取代模式和开发构象受限的类似物，增加了 CBP 超过 BRD4(1) 的选择性。优化后的化合物具有高效 (Kd
