and structure‐activity relationships (SAR) for a series of novel γ‐carboline analogues of Dimebon are described. Among the studied compounds, tetrahydro‐γ‐carboline 5b (2,8‐dimethyl‐5‐[cis‐2‐pyridin‐3‐ylvinyl]‐2,3,4,5‐tetrahydro‐carboline) has been identified as the most potent small molecule antagonist, in particular against histamine H1 and serotonin 5‐HT6 receptors (IC50 < 0.45 μM and IC50 = 0.73
描述了 Dimebon 的一系列新型 γ-咔啉类似物的合成、生物学评价和构效关系 (SAR)。在研究的化合物中,四氢-γ-咔啉 5b(2,8-二甲基-5-[cis-2-pyridin-3-ylvinyl]-2,3,4,5-四氢咔啉)已被鉴定为最有效的小分子拮抗剂,特别是针对组胺 H1 和血清素 5-HT6 受体(IC50 < 0.45 μM 和 IC50 = 0.73 μM,分别)。对测试化合物进行的全面比较 SAR 研究揭示了侧取代基的性质与相关拮抗活性之间的显着相关性。
