Excitatory amino acid receptor antagonists and methods for the use thereof are disclosed. The antagonists include compounds having the preferred formula: ##STR1## in which: each of A.sub.1, A.sub.2 and A.sub.3 is independently either C or N, except that at least one of A.sub.1, A.sub.2 and A.sub.3 is N; one of A.sub.4 and A.sub.5 is C and the other is N; each R.sub.1 and R.sub.2 is independently hydrogen, halogen, CN, NO.sub.2, alkyl, aromatic, azido or CF.sub.3 ; and R.sub.3 is hydrogen, alkyl, aromatic or CF.sub.3. Also included are the tautomers thereof, and the pharmaceutically acceptable salts of (III) and (IV) and the tautomers thereof. These compounds are useful as EAA antagonists for blocking one or more EAA receptors, as neurological disorders associated with EAA receptors.
揭示了兴奋性氨基酸受体拮抗剂及其使用方法。这些拮抗剂包括具有优选式的化合物:##STR1## 其中:A.sub.1、A.sub.2和A.sub.3中的每一个独立地是C或N,除了至少有一个A.sub.1、A.sub.2和A.sub.3是N;A.sub.4和A.sub.5中的一个是C,另一个是N;每个R.sub.1和R.sub.2独立地是氢、卤素、CN、NO.sub.2、烷基、芳香、叠氮基或CF.sub.3;R.sub.3是氢、烷基、芳香或CF.sub.3。还包括它们的互变异构体,以及(III)和(IV)及其互变异构体的药用盐。这些化合物可用作EAA拮抗剂,用于阻断一个或多个EAA受体,治疗与EAA受体相关的神经系统疾病。
