3-Substituted 6-phenyl-4H-imidazo[1,5-a][1,4]benzodiazepines and related compounds were synthesized as central benzodiazepine receptor (CBR) ligands. Most of the compounds showed high affinity for bovine and human CBR, their Ki values spanning from the low nanomolar to the submicromolar range. In particular, imidazoester 5f was able to promote a massive flow of 36Cl– in rat cerebrocortical synaptoneurosomes
合成了3-取代的6-苯基-4 H-咪唑并[1,5- a ] [1,4]苯并二氮杂and和相关化合物作为中心苯并二氮杂receptor受体(CBR)配体。大多数化合物显示出对牛和人CBR的高亲和力,它们的K i值范围从低纳摩尔到亚微摩尔范围。特别是,imidazoester 5F是能够促进了大规模的流动36氯-在大鼠大脑皮层synaptoneurosomes与典型的完全激动剂的重叠其功效特征。化合物5f然后在小鼠中检查其药理作用,证明其是安全的抗焦虑药,没有经典的1,4-苯并二氮杂卓类药物的令人不悦的肌松和健忘作用。此外,一些选择的化合物的选择性已经评估了重组α 1 β 2 γ 2 L,α 2 β 1 γ 2 L,和α 5 β 2 γ 2大号人GABA甲受体。最后,将某些化合物连同Cromer GABA A同源性模型中的分子动力学模拟一起进行了分子对接计算。
