in potent CB2 antagonists (27 or 28, IC50 = 16–28 nM). Replacement of the amidoalkyls from 3-position to the 2-position of the indole ring dramatically increased the agonist selectivity on the CB2 over CB1 receptor. Particularly, compound 57 displayed a potent agonist activity on the CB2 receptor (EC50 = 114–142 nM) without observable agonist or antagonist activity on the CB1 receptor. Furthermore,
选择性CB 2激动剂代表了一种有吸引力的治疗策略,可用于治疗各种疾病,而无需CB 1受体介导的精神病副作用。我们对黑市设计师药物SDB-001进行了合理的优化,从而确定了有效的和选择性的CB 2激动剂。3-氨基烷基吲哚处的7-甲氧基或7-甲硫基取代产生有效的CB 2拮抗剂(27或28,IC 50 = 16-28 nM)。从吲哚环的3位到2位取代酰胺基烷基大大提高了CB 2上的激动剂选择性,而不是CB 1上受体。特别是,化合物57对CB 2受体表现出有效的激动剂活性(EC 50 = 114–142 nM),而对CB 1受体没有明显的激动剂或拮抗剂活性。此外,在多发性硬化症的实验性自身免疫性脑脊髓炎(EAE)小鼠模型中,有57个显着减轻了临床症状并保护了小鼠中枢神经系统免受免疫损伤。
