A series of novel 3-(1H-indol-3-yl)pyrrolidine-2,5-dione derivatives were synthesised and evaluated for their 5-HT1A/D2/5-HT2A/5-HT6/5-HT7 receptor affinity and serotonin reuptake inhibition. Most of the evaluated compounds displayed high affinities for 5-HT1A receptors (e.g., 4cKi = 2.3 nM, 4lKi = 3.2 nM). The antidepressant activity of the selected compounds was screened in vivo using the forced swim test (FST). The results indicate that compound MW005 (agonist of the pre- and postsynaptic 5-HT1A receptor) exhibited promising affinities for the 5-HT1A/SERT/D2/5-HT6/5-HT7 receptors and showed an antidepressant-like activity in the FST model.

具有潜在抗抑郁作用的新型多目标3-（1H-吲哚-3-基）吡咯烷-2,5-二酮衍生物的合成和生物学评价。

合成了一系列新颖的3-（1H-吲哚-3-基）吡咯烷-2,5-二酮衍生物并评估了它们的5-HT1A / D2 / 5-HT2A / 5-HT6 / 5-HT7受体亲和力和血清素再摄取抑制。大多数评估的化合物显示出对5-HT1A受体的高亲和力（例如4cKi = 2.3 nM，4lKi = 3.2 nM）。使用强制游泳测试（FST）在体内筛选了所选化合物的抗抑郁活性。结果表明，化合物MW005（突触前5-HT1A受体激动剂）对5-HT1A / SERT / D2 / 5-HT6 / 5-HT7受体表现出有希望的亲和力，并在FST中表现出抗抑郁样活性模型。
