The discovery of a novel, selective and fully efficacious CB agonist with satisfactory pharmacokinetic and pharmaceutical properties is described. Compound was efficacious in a rat model of osteoarthritis pain following oral administration and, in contrast to morphine, maintained its analgesic effect throughout a 5-day subchronic treatment paradigm. These data were consistent with our hypothesis that full agonist efficacy is required for efficient internalization and recycling of the CB receptor to avoid tachyphylaxis. Based on its overall favorable preclinical profile, (APD371) was selected for further development for the treatment of pain.
本文描述了一种新型、选择性且完全有效的CB激动剂的发现,其具有令人满意的药代动力学和药物性质。化合物在口服给药后对骨关节炎疼痛的大鼠模型有效,并且与吗啡不同,在为期5天的亚慢性治疗模式中维持其镇痛效果。这些数据与我们的假设一致,即CB受体的有效内化和再循环需要完全激动剂效力以避免快速耐受性。基于其总体良好的临床前特征,选择(APD371)进行疼痛治疗的进一步开发。
