A series of 3-[3-(4-aryl-1-piperazinyl)-propyl]-1H-indole derivatives (12a–h) was synthesized and evaluated for binding affinity at the human 5-hydroxytryptamine1A receptor (5-HT1AR) compounds (12b) and (12h) showed the highest 5-HT1A receptor affinity (IC50=15 nM). Molecular docking studies with all the compounds in a homology model of 5-HT1A showed that the main interaction anchoring the ligand in the receptor was a charge-reinforced bond between the protonated nitrogen atom (N-4) of the piperazine ring and Aspartate3.32.
合成了一系列3-[3-(4-芳基-1-哌嗪基)-丙基]-1H-吲哚衍生物(12a–h),并评估了它们与人5-羟色胺1A受体(5-HT1AR)的结合亲和力。化合物(12b)和(12h)显示出最高的5-HT1A受体亲和力(IC50=15 nM)。分子对接研究表明,所有化合物在5-HT1A的同源模型中,主要通过哌嗪环的质子化氮原子(N-4)与天冬氨酸3.32之间形成的强化学键来锚定配体。
