There is growing interest in using cannabinoid receptor 2 (CB2) agonists for the treatment of neuropathic pain. We have synthesized a novel series of N-alkyl isatin acylhydrazone derivatives and have identified and characterized several of them as novel analogues with high functional activity and selectivity at human CB2 receptors using [(35)S]GTP-gamma-S assays. Binding affinities at human CB2 and
使用大麻素受体2(CB2)激动剂治疗神经性疼痛的兴趣日益浓厚。我们已经合成了一系列新的N-烷基Isatin酰基hydr衍生物,并使用[(35)S]GTP-γ-S分析法鉴定和表征了其中几种作为具有高功能活性和对人CB2受体的选择性的新型类似物。确定了化合物28、33、40、48和58在人CB2和CB1上的结合亲和力。这一新型系列的结构活性关系研究导致对我们的先导化合物化合物33(MDA19)进行了优化。化合物33在神经性疼痛的大鼠模型中具有有效的抗痛觉过敏作用,但不影响大鼠的运动活性。还发现了更有效和更强的CB2受体选择性化合物,包括化合物37、40和48。
