The isoxazole amino acid 2-amino-3-(3-hydroxy-5-methylisoxazol-4-yl) propionic acid (AMPA) (1), which is a highly selective agonist at the AMPA subtype of excitatory amino acid (EAA) receptors, has been used as a lead for the development of two novel EAA receptor antagonists. One of the compounds, 2-amino-3-[3-(carboxymethoxy)-5-methylisoxazol-4-yl]propionic acid (AMOA, 7), was synthesized via O-alkylation
异恶唑氨基酸2-氨基-3-(3-羟基-5-甲基异恶唑-4-基)丙酸(AMPA)(1)是对兴奋性氨基酸(EAA)受体AMPA亚型的高度选择性激动剂,已被用作开发两种新型EAA受体拮抗剂的先导。一种化合物是2-氨基-3- [3-(羧基甲氧基)-5-甲基异恶唑-4-基]丙酸(AMOA,7),是通过氯乙酸乙酯的O-烷基化反应制得的氨基酸保护的AMPA衍生物4.另一种化合物2-氨基-3- [2-(3-(3-羟基-5-甲基异恶唑-4-基)-甲基-5-甲基-3- + ++氧代恶唑啉-4-基]丙酸(AMNH使用4-(氯甲基)-3-甲氧基-5-甲基异恶唑(8)作为起始原料合成了(14)。将中间体4-(氯甲基)-2-(3-甲氧基-5-甲基异恶唑-4-基)甲基-5-甲基thyoxoxazolin-3(11)转化为乙酰氨基丙酸酯(12),将其逐步脱保护为得到14。化合物7和14在水溶液中在接近生理pH的pH值下稳
