Under pathophysiological conditions, alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionate (AMPA) receptor activation is considered to play a key role in several disorders of the central nervous system. In the search for AMPA receptor antagonists, the synthesis and pharmacological characterization of a series of novel compounds that are structurally related to GYKI 52466 (1), a well-known selective
在病理生理条件下,丙酸α-氨基-3-羟基-5-羟基-5-甲基-4-异恶唑(AMPA)受体活化被认为在中枢神经系统的多种疾病中起关键作用。在寻找AMPA受体拮抗剂时,进行了一系列与众所周知的选择性非竞争性AMPA受体拮抗剂GYKI 52466(1)在结构上相关的新型化合物的合成和药理学表征。在体外,2,3-二甲基-6-苯基-12H- [1,3]二恶唑[4,5-h]咪唑并[1,2-c] [2,3]苯并二氮杂((ZK 187638,14a)拮抗海藻酸盐诱导的电流以非竞争性方式以3.4 microM的IC(50)培养的海马神经元中。当在急性缺血性中风的临床预测大鼠模型中进行测试时,这种非竞争性AMPA受体拮抗剂可显着减少脑梗塞,
