New cyclofunctionalized 2,3-benzodiazepines characterized by a triazolone or triazindione ring fused on the "c" edge of the heptatomic nucleus have been prepared. These compounds were evaluated as potential anticonvulsant agents, and some of them proved to be more potent noncompetitive 2-amino-3-(3-hydroxy-5-methylisoxazol-4-yl)propionate (AMPA) receptor antagonists. In particular, 8,9-dimethoxy-6
已经制备了特征为三唑酮或三嗪酮环稠合在七原子核的“ c”边缘上的新的环官能化的2,3-苯并二氮杂卓。这些化合物被评估为潜在的抗惊厥药,其中一些被证明是更有效的非竞争性2-氨基-3-(3-羟基-5-甲基异恶唑-4-基)丙酸酯(AMPA)受体拮抗剂。特别是8,9-二甲氧基-6-(4-溴苯基)-11H- [1,2,4]三唑并[4,5-c] [2,3]苯并二氮杂-3-3(2H)-一(5b)其活性比GYKI-52466高出近10倍,比Talampanel高出3.5倍。此外,在电生理实验中,5b有效降低了AMPA诱发的电流。
