A series of 2,3-benzodiazepine derivatives has been previously described as noncompetitive AMPA-type glutamate receptor antagonists potentially useful for treatment of epilepsy. To further explore the structure-activity relationships of AMPA antagonists, a series of 11H-[1,2,4]triazolo[4,5-c][2,3]benzodiazepin-3(2H)-ones (6) was synthesized starting from the corresponding bicyclic 1-aryl-3, 5-dihydro-7
先前已将一系列2,3-苯并二氮杂pine衍生物描述为非竞争性AMPA型谷氨酸受体拮抗剂,可用于治疗癫痫。为了进一步探索AMPA拮抗剂的构效关系,合成了一系列11H- [1,2,4]三唑并[4,5-c] [2,3]苯并二氮杂-3(2H)-(6)从相应的双环1-芳基-3,5-二氢-7,8-二甲氧基-4H-2,3-苯并二氮杂-4--4-酮(2,CFM)开始。发现新化合物具有抗惊厥作用,可对抗DBA / 2小鼠的听觉刺激和瑞士小鼠中的戊四唑或最大电击诱发的癫痫发作。另外,它们拮抗AMPA诱导的癫痫发作,并且其抗惊厥活性通过用阿尼西坦预处理而逆转,因此暗示了AMPA受体的参与。药理研究表明,本文报道的11H- [1,2,4]三唑并[4,5-c] [2,3]苯并二氮杂-3-(2H)-ones(6)显示出与它们的双环类似的抗惊厥活性前体。此外,HPLC研究表明,这些三环衍生物6在体内被转化为相应的2,这
