with a pyrazolo[5,1-c][1,2,4]benzotriazine core to identify ligands on GABAA receptors subtype (benzodiazepine site on GABAA-receptor) endowed with the potential of enhancing cognition activity without the side effects usually associated with non-selective GABAA modulators. In fact, there is much evidence that GABAA-R (γ-aminobutyric acid, type A receptor) subtype ligands have relevance in learning
与衰老,神经退行性疾病和精神疾病相关的记忆功能障碍代表了日益增长的医疗需求。探索学习和记忆基础的生物学机制的研究进展为开发针对选择性神经元靶标的记忆增强疗法开辟了新的潜在方法。在这项工作中,我们合成了一些具有吡唑并[5,1- c ] [1,2,4]苯并三嗪核心的衍生物,以鉴定具有增强潜力的GABA A受体亚型(GABA A受体上的苯二氮卓部位)上的配体无副作用的认知活动通常与非选择性GABA A调节剂有关。实际上,有很多证据表明GABA A-R(γ-氨基丁酸,A型受体)亚型配体与学习和记忆有关。已经进行了体外和体内测试。药理学数据表明,化合物7,13,14和22充当GABA的双重功能调节剂阿-Rs(promnemonic和抗焦虑药),而仅化合物3和10立场选择性地显示良好antiamnesic和促认知活性(1和3mg /公斤)。
