2-fluoro and 3-trifluoromethylphenylpiperazinylalkyl derivatives of 1H-imidazo[2,1-f]purine-2,4(3H,8H)-dione (4-21) were synthesized and evaluated for their serotonin (5-HT1A/5-HT7) receptor affinity and phosphodiesterase (PDE4B and PDE10A) inhibitor activity. The study enabled the identification of potent 5-HT1A, 5-HT7 and mixed 5-HT1A/5-HT7 receptor ligands with weak inhibitory potencies for PDE4B and PDE10A
合成了一系列的1H-咪唑并[2,1-f]嘌呤-2,4(3H,8H)-二酮(4-21)的2-氟和3-三氟甲基苯基哌嗪基烷基衍生物,并对其5-羟色胺(5-HT1A)进行了评估/ 5-HT7)受体亲和力和磷酸二酯酶(PDE4B和PDE10A)抑制剂的活性。该研究能够鉴定出对PDE4B和PDE10A具有弱抑制能力的有效5-HT1A,5-HT7和混合的5-HT1A / 5-HT7受体配体。已经使用胶束电动色谱(MEKC)系统和人肝微粒体(HLM)模型确定了亲脂性和代谢稳定性,从而完成了测试。在体内初步药理研究中,选择化合物8-(5-(4-(2-氟苯基)哌嗪-1-基)戊基)-1,3,7-三甲基-1H-咪唑并[2,1-f]嘌呤-2,4(3H,8H)-二酮(9)在小鼠的强迫游泳试验(FST)中表现为潜在的抗抑郁药。此外,由9引起的抗焦虑作用(2.5 mg / kg)要大于参考抗焦虑药地西epa。分子建模表明,1H-咪唑并[2
