  融合的咪唑并吡啶的合成与构效关系：一系列苯二氮杂ze受体配体

  摘要：

  合成了2-Arylimidazo [4,5-c]喹啉和类似的稠合咪唑并吡啶，并评价为苯并二氮杂receptor受体配体。与吡唑并喹啉如CGS-9896相比，与受体的亲和力受2-位芳基庞大性的影响。在2-位具有异恶唑部分的衍生物显示出高结合亲和力和体内活性。在咪唑并[4,5-c]喹啉系列中，在6-位的取代降低或消除了活性。除7-卤代类似物外，大多数具有未取代异恶唑基的衍生物均表现出拮抗或反向激动剂活性。另一方面，5-甲基异恶唑-3-基或3-甲基异恶唑-5-基衍生物通常表现出激动剂活性。在与非芳族环稠合的咪唑并吡啶中观察到对异恶唑部分的类似取代作用。根据详细的药理评估，S-8510，2-（3-异恶唑基）-3,6,7,9-四氢咪唑并[4,5-d]吡喃++ + [4,3-b]吡啶一磷酸具有弱的反向激动剂选择活性作为治疗老年性痴呆某些症状的治疗候选药物。
