fluorophore attachment. A new high affinity, CB2 receptor selective inverse agonist was identified (16b) along with a general trend of C5-substituted indoles acting as agonists versus C7-substituted indoles acting as inverse agonists. The indole C7 position was found to be the most tolerant to linker extension and resulted in a high affinity inverse agonist with a medium length linker (19). Although a
大麻素 2 型 (CB2) 受体继续成为许多疾病和病症的有前途的药物靶点。需要研究 CB2 受体的新工具,以进一步了解该受体在健康和疾病状态下的功能。烷基吲哚支架是公认的大麻素受体配体,在这项研究中,探索了吲哚 C5-7 位置的连接子和荧光团附着。确定了一种新的高亲和力、CB2 受体选择性反向激动剂 (16b) 以及 C5 取代的吲哚作为激动剂与 C7 取代的吲哚作为反向激动剂的一般趋势。研究发现,吲哚 C7 位置对接头延伸最耐受,并导致具有中等长度接头的高亲和力反向激动剂 (19)。尽管本研究未发现 CB2 受体的高亲和力荧光配体,但吲哚 C7 位置在荧光团或探针附着方面显示出巨大的前景。
