homologous series of acidic amino acids, ranging from aspartic acid (1) to 2-aminosuberic acid (5), and the corresponding series of 3-isoxazolol bioisosteres of these amino acids, ranging from (RS)-2-amino-2-(3-hydroxy-5-methylisoxazol-4-yl)acetic acid (AMAA, 6) to (RS)-2-amino-6-(3-hydroxy-5-methylisoxazol-4-yl)hexanoic acid (10), were tested as ligands for metabotropic excitatory amino acid receptors (mGlu1
从天冬氨酸(1)到2-氨基异丁烯酸(5)的酸性氨基酸的同源序列以及这些氨基酸的相应的3-isoxazolol生物异构体的序列,从(RS)-2-amino-2- (3-羟基-5-甲基异恶唑-4-基)乙酸(AMAA,6)至(RS)-2-氨基-6-(3-羟基-5-甲基异恶唑-4-基)己酸(10),将其作为代谢型兴奋性氨基酸受体(mGlu1 alpha,mGlu2,mGlu4a和mGlu6)的配体进行测试。而AMAA(6)和(RS)-2-氨基-3-(3-羟基-5-甲基异恶唑-4-基)丙酸(AMPA,7)是对N-甲基-D-天冬氨酸有效且高度选择性的激动剂酸(NMDA)和AMPA受体,分别是AMPA(7),(RS)-2-氨基-4-(3-羟基-5-甲基异恶唑-4-基)丁酸(homo-AMPA,8)的较高同源物),对离子型兴奋性氨基酸受体无活性。Homo-AMPA(8),然而,它是2-氨基己二酸的3-is
