设计并合成了一系列咪唑并[1,5- a ]喹啉衍生物作为中心苯并二氮杂pine受体(CBR)配体。大多数化合物在亚微摩尔和亚纳摩尔范围内都具有很高的CBR亲和力和K i值,并在其结构亲和力关系中进行了有趣的调节。特别是,氟衍生物7w(K i = 0.44 nM)导致了迄今为止所述的咪唑并[1,5- a ]喹啉衍生物中最有效的配体。总体而言,这些观察结果证实了以下假设:在与咪唑[1,5-]的位置4和5相互作用的CBR结合位点区域中存在一个明显饱和的亲脂性大袋。一个]喹啉核。体内生物学特性表明,化合物7a,c,d,l,m,q,r,w显示出抗焦虑和抗记忆删除活性,而没有经典的1,4-BDZ的令人讨厌的肌松反应副作用。此外,7l,q,r和8i降低大鼠脑切片中缺血样条件引起的乳酸脱氢酶(LDH)释放的作用表明这些咪唑并[1,5- a ]喹啉衍生物具有神经保护作用。
