Several N1 side chains afforded potent and CB2-selective neutral antagonists, notably derivatives 26 (R1 = n-propyl, R2 = H) and 35 (R1 = 4-pentynyl, R2 = H). Addition of a methyl group at C2 improved the selectivity for the CB2 receptor. Moreover, C2 indole substitution may control the CB2 activity as shown by the functionality switch in 35 (antagonist) and 49 (R1 = 4-pentynyl, R2 = CH3, partial agonist)
合成吲哚大麻素的特征是在吲哚 C3 位上具有 2',2'-二甲基茚满-5'-酰基,构成一类新型配体,在纳摩尔浓度下对人 CB 2受体具有高亲和力和良好的选择性指数。从中性拮抗剂4开始,研究了吲哚核心修饰对配体药效学特征的影响。几个N1侧链提供了有效的CB 2选择性中性拮抗剂,特别是衍生物26(R 1 =正丙基,R 2 = H)和35(R 1 = 4-戊炔基,R 2 = H)。在 C2 处添加甲基提高了对 CB 2受体的选择性。此外,C2吲哚取代可以控制CB 2活性,如35(拮抗剂)和49(R 1 = 4-戊炔基,R 2 = CH 3,部分激动剂)中的功能开关所示。
