series of substituted 3-(2-carboxyindol-3-yl)propionic acids was synthesized and tested as antagonists for the strychnine-insensitive glycine binding site of the NMDA receptor. Chlorine, and other small electron-withdrawing substituents in the 4- and 6-positions of the indole ring, greatly enhanced binding and selectivity for the glycine site over the glutamate site of the NMDA receptor; one of the most
合成了一系列取代的3-(2-羧基吲哚-3-基)丙酸,并测试了它们对NMDA受体的对苯丙氨酸不敏感的甘氨酸结合位点的拮抗剂。吲哚环的4位和6位上的氯以及其他小的吸电子取代基大大增强了NMDA受体谷氨酸位点上甘氨酸位点的结合和选择性。最有效的化合物之一是3-(4,6-二氯-2-羧基吲哚-3-基)丙酸(IC50 = 170 nM;对甘氨酸的选择性大于2100倍)。已经证明了杂原子NH的重要性和丙酸侧链的增强作用,并且与先前的结果一致,该结果表明在受体上存在可以接受酸性侧链的口袋。
