The cannabinoid type 2 receptors (CB2Rs) play crucial roles in inflammatory diseases. There has been considerable interest in developing potent and selective ligands for CB2R. In this study, quinoline-2,4(1H,3H)-dione analogs have been designed, synthesized, and evaluated for their potencies and binding properties toward the cannabinoid type 1 receptor (CB1R) and CB2R. C5- or C8-substituted quinoline-2
大麻素2型受体(CB2Rs)在炎症性疾病中起关键作用。对于开发CB2R的有效和选择性配体已经引起了相当大的兴趣。在这项研究中,喹啉-2,4(1 H,3 H)-二酮类似物已被设计,合成并评估了它们对大麻素1型受体(CB1R)和CB2R的效力和结合特性。C5-或C8-取代的喹啉-2,4(1 H,3 H)-二酮显示CB2R激动剂活性,而C6-或C7-取代的类似物是CB2R的拮抗剂。另外,口服21剂量依赖性地减轻多发性硬化症小鼠模型中实验性自身免疫性脑脊髓炎的临床症状,并保护中枢神经系统免受免疫损伤。此外,通过对接仿真预测的交互模式以及使用CoMFA生成的3D-QSAR模型可以为进一步设计和修改CB2R调制器提供指导。
