Selective CB2 receptor agonists are promising potential therapeutic agents for the treatment of inflammatory and neuropathic pain. A focused screen identified a pyrimidine ester as a partial agonist at the CB2 receptor with micromolar potency. Subsequent lead optimization identified 35, GW842166X, as the optimal compound in the series. 35 has an oral ED50 of 0.1 mg/kg in the rat FCA model of inflammatory pain and was selected as a clinical candidate for this indication.
选择性CB2受体激动剂有望成为治疗炎症性疼痛和神经性疼痛的潜在治疗药物。一项重点筛选确定了一种嘧啶酯作为CB2受体的部分激动剂,其效力为微摩尔级。随后的先导化合物优化确定了35(GW842166X)为该系列中的最佳化合物。在大鼠佐剂性关节炎(FCA)炎症性疼痛模型中,35的口服半数有效剂量(ED50)为0.1mg/kg,并被选为该适应症的临床候选药物。
