and nine of them exhibited Ki values below nanomolar concentrations. The best scores were always obtained when the 5-phenyl-2-thiophenyl core was attached to the triazole. The selectivity of these compounds towards the nicotinic α4β2 and serotoninergic 5HT3 receptors was assessed and their brain penetration was quantified by the preparation and in vivo evaluation of two [18F] radiolabelled derivatives
在本文中,我们描述了使用有效的三步序列(包括与市售的硼衍生物和自制的硼衍生物的Suzuki-Miyaura交叉偶联反应)设计和合成双(Het)芳基-1,2,3-三唑喹核苷α7R配体的方法。 。SAR的勘探需要制备罕见的硼衍生物。测试了40种最终药物结合靶标的能力,其中9种药物的Ki值低于纳摩尔浓度。当将5-苯基-2-硫代苯基核心连接到三唑上时,总会获得最高分。通过制备和体内评估两种化合物,评估了这些化合物对烟碱型α4β2和5羟色胺能5HT3受体的选择性,并定量了它们的脑渗透率[ 18F]放射性标记的衍生物。从我们的结果可以预期,这些化合物中的一些将适合进一步发展,并将对认知障碍产生影响。
