  摘要：

  二十多年前，喹喔啉二酮支架被证明是α-氨基酸的生物等排体。经过广泛的结构-活性关系（SAR）研究，在离子型谷氨酸受体领域确定了拮抗剂DNQX，CNQX和NBQX。在这项工作中，我们将重新研究喹喔啉二酮支架，并探索在6位上引入酸官能团的方法。SAR研究表明，通过这种策略，可以调节AMPA，NMDA和KA受体之间的iGluR选择性，并且在某种程度上还可以获得完全的受体亚型选择性。研究44个新类似物的重点是化合物2m是天然AMPA受体的高亲和力配体（IC 50 = 0.48μM），类似物2e，f，h，k，v均显示出对天然NMDA受体的选择性，化合物2s，t，u是GluK1受体的选择性配体。最有趣的是，化合物2w被证明是GluK3优先配体，对天然AMPA，KA和NMDA受体具有完全选择性。
