significant to moderate affinities for 5-HT1A receptors in nanomolar range (7–610 nM). The highest activity (7 nM) and selectivity (17.38) for 5-HT1A was observed for 1-(3-(4-(2-ethoxyphenyl)piperazin-1-yl)-2-hydroxypropyl)-3-methyl-5,5-diphenylimidazolidine-2,4-dione (13a). Among new synthesized compounds 1-(2-hydroxy-3-(4-(2-methoxyphenyl)piperazin-1-yl)propyl)-5,5-diphenylimidazolidine-2,4-dione hydrochloride
该研究集中于1-(2-羟基-3-(4-芳基哌嗪-1-基)丙基)-5,5-二苯基咪唑烷-2,4-二酮的(2-烷氧基)苯基哌嗪衍生物,具有烷基或酯取代基乙内酰脲环的N3处,以及新设计和合成的一系列具有游离N3H基团或N3-乙酸末端片段的化合物。将化合物在他们的亲和力评估5-HT 1A和α 1 -肾上腺素受体和用于拮抗性能的功能生物测定法进行评价。使用经典分子力学(MMFFs力场,MCMM,MacroModel)和DFT方法(B3LYP功能,高斯0.3)研究化合物的3D结构。SAR分析基于两种药效团模型,Barbaro等人描述了一种。对于α 1-腺苷受体拮抗剂和Lepailleur等人的模型。用于5-HT 1A受体配体。所有化合物均对纳摩尔浓度范围(7–610 nM)的5-HT 1A受体表现出显着至中等的亲和力。最高活性(7纳米)和选择性(17.38)对5-HT 1A,观察到了1-(3-(4-(
