method. Selected compounds were also evaluated for benzodiazepine receptor binding properties and in vivo antagonist potential. Although the compounds lack potency, the data suggest that previously inaccessible substituted analogues may be useful to segregate the proconvulsant , anticonvulsant, and antagonist actions of benzodiazepines and quinazolines.
一系列4,6,7,8-四取代的3,4-二氢喹唑啉,喹唑啉,喹唑啉-2-酮,1,2,3,4-四氢喹唑啉-2-酮和5,7,8,9-四取代通过利用呋喃邻氨基腈与各种烷基或芳基乙烯基酮二亲二烯物之间的狄尔斯-阿尔德反应合成1,4-苯并二氮杂卓,以获得邻氨基苯甲酸前体。在小鼠中评估所有新合成的目标化合物的抗惊厥活性。通过定时静脉内戊四氮癫痫发作阈值方法对促惊厥作用和抗惊厥作用进行定量。还评估了所选化合物的苯并二氮杂receptor受体结合特性和体内拮抗剂潜力。尽管这些化合物缺乏药效,但数据表明,以前难以获得的取代类似物可能对分离前惊厥药,
