We have previously reported the synthesis and pharmacological characterization of analogues of 2‐amino‐3‐(3‐hydroxy‐5‐methyl‐4‐isoxazolyl)propionic acid (AMPA, 1a), in which the methyl group was replaced by a phenyl group (APPA, 1b) or heteroaryl groups. While 2b and its 3‐pyridyl analogue 2‐amino‐3‐[3‐hydroxy‐5‐(3‐pyridyl)‐4‐isoxazolyl]propionic acid (3‐Py‐AMPA, 3) show very low affinity for AMPA
我们之前已经报道了 2-氨基-3-(3-羟基-5-甲基-4-异恶唑基)丙酸 (AMPA, 1a) 类似物的合成和药理学表征,其中甲基被苯基取代(APPA, 1b) 或杂芳基。虽然 2b 及其 3-吡啶基类似物 2-氨基-3-[3-羟基-5-(3-吡啶基)-4-异恶唑基]丙酸 (3-Py-AMPA, 3) 对 AMPA 受体的亲和力非常低,在 2 位引入含有杂原子的杂芳基取代基提供了有效的 AMPA 受体激动剂。我们在此报告了 2-氨基-3-(3-羟基-5-吡嗪基-4-异恶唑基)丙酸 (7) (IC50 = 1.2 μM; EC50 = 11 μM) 的合成和药理学,其较弱AMPA 激动剂比 AMPA (IC50 = 0.040 μM; EC50 = 3.5 μM) 但在效力上与 2-Py-AMPA (4) (IC50 = 0.57 μM; EC50 = 7.4 μM) 相当,分别在放射性配
