reported as a potent 5-HT1AR agonist with a moderate 5-HT1AR selectivity. In an extension of this work a series of derivatives of 1, obtained by combining different heterocyclic rings with a more flexible amine chain, was synthesized and tested for binding affinity and activity at 5-HT1AR and α1 adrenoceptors. The results led to the identification of 14 and 15 as novel 5-HT1AR partial agonists, the first
最近,据报道1-(1,4-二氧杂螺并[4,5]癸-2-基甲基)-4-(2-甲氧基苯基)哌嗪(1)是有效的5-HT 1A R激动剂,具有中等的5-HT 1A R选择性。在这项工作中的一系列的衍生物的延伸1,通过不同的杂环与一个更灵活的胺链合成而获得,合成并在5-HT的结合亲和力和活性进行测试1A R和α 1种肾上腺素受体。结果导致鉴定出14和15种新颖的5-HT 1A R部分激动剂,其中第一种在选择性方面非常出色(5-HT 1A / α1d = 80),后者的效价(pD 2 = 9.58)和功效(E max = 74%)。ADME性质的理论研究表明,整个系列具有良好的分布,而MDCKII-MDR1细胞的通透性数据预测化合物15具有良好的BBB通透性,具有良好的神经保护活性。此外,在小鼠福尔马林测试中,化合物15显示出有效的抗伤害感受活性,表明了一种新的疼痛控制策略。
