制备方法与用途

生物活性

Olorinab (APD 371) 是一种强有效的、选择性的全激动剂，专门针对大麻素受体 2 型（CB2），其对 hCB2 的 EC50 值为 6.2 nM。

靶点

• EC50: 6.2 nM (hCB2)。

体外研究

Olorinab (APD 371) 在多种物种中表现出单位纳米摩尔级的效力和全内在效应，且在结合和功能试验中对 CB2 的选择性远高于 CB1。此外，该化合物在表达 HA 标签的大鼠 CB2 阳性 CHO 细胞中诱导了高效的受体内化（约 106% 相对于 CB1/2 激动剂 CP55,940），这表明 Olorinab (APD 371) 可能能够驱动激动剂引起的受体循环。

体内研究

• 单剂量 Olorinab (APD 371)（10 mg/kg，口服）在给药后 4 小时内显著增加足爪撤回阈值。ED50 值为 2.3 mg/kg。
• 单独的实验表明，Olorinab (APD 371) 的镇痛效果很大程度上是由 CB2 受体介导的。

  The discovery of a novel, selective and fully efficacious CB2 agonist with satisfactory pharmacokinetic and pharmaceutical properties is described. Compound 6 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 CB2 receptor to avoid tachyphylaxis. Based on its overall favorable preclinical profile, 6 (APD371) was selected for further development for the treatment of pain.
