long-chain arylpiperazine derivatives with semi-rigid alkylene spacer was designed, synthesized, and biologically evaluated using in vitro methods for their affinity for dopaminergic D2 and serotoninergic 5-HT1A, 5-HT2A, 5-HT6 and 5-HT7 receptors. Docking to homology models revealed a possible halogen bond formation in complexes of the most potent ligands and the target receptors. The study allowed for
设计,合成了一系列带有半刚性亚烷基间隔基的长链芳基哌嗪衍生物的嗪磺酰胺,并通过体外方法对其多巴胺能D 2和5-羟色胺能5-HT 1A,5-HT 2A,5-HT的亲和力进行了生物学评估。6和5-HT 7受体。与同源模型的对接表明,在最有效的配体和目标受体的复合物中可能形成卤素键。该研究允许鉴定化合物5-(4-(2- [4-(2,3-二氯苯基)哌嗪-1-基]乙基)哌啶-1-基}磺酰基)喹啉(21)如d 2,5-HT 1A和5-HT 7受体拮抗剂。在体内的初步研究中,化合物21在MK-801诱发的小鼠多动症试验中以10 mg / kg的剂量表现出独特的抗精神病特性,并在小鼠的强迫游泳试验中发挥抗抑郁样作用(MED = 0.625 mg / kg,ip。)。
