We describe the synthesis of 5-aminoethyl- and 6-aminomethyl-4-oxotetrahydroindoles as butyrophenone derivatives in the indole series, as potential atypical antipsychotics. The affinities of these compounds for serotonin (5-HT2A) and dopamine (D2) receptors were evaluated in vitro. The ratios of pKi's for 5-HT2A/D2 receptors may be useful for rapid screening of new compounds and assessing potential induction of extrapyramidal symptoms; ratio values ≥1.12 (Meltzer's ratio) are predictive of an atypical antipsychotic profile. Compounds 26e (QF 0408B) and 26f (QF 0409B) showed high affinity for both D2 and 5-HT2A receptors, and their MEltzer's ratios were 1.32 and 1.17 respectively, while haloperidol showed a ratio of 0.93.
我们介绍了作为吲哚系列丁酮衍生物的 5-氨基乙基和 6-氨基甲基-4-氧代四氢吲哚的合成,它们是潜在的非典型抗精神病药物。这些化合物与血清素(5-HT2A)和多巴胺(D2)受体的亲和力在体外进行了评估。5-HT2A/D2受体的pKi比值可用于快速筛选新化合物和评估诱发锥体外系症状的可能性;比值≥1.12(Meltzer比值)可预测非典型抗精神病药的特征。化合物 26e(QF 0408B)和 26f(QF 0409B)显示出对 D2 和 5-HT2A 受体的高亲和力,它们的梅尔策尔比值分别为 1.32 和 1.17,而氟哌啶醇的比值为 0.93。
