A series of 5-, 6-, 7- and 8-aza analogues of 3-aryl-4-hydroxyquinolin-2(1H)-one was synthesized and assayed as NMDA/glycine receptor antagonists. The in vitro potency of these antagonists was determined by displacement of the glycine site radioligand [(3)H]5,7-dicholorokynurenic acid ([(3)H]DCKA) in rat brain cortical membranes. Selected compounds were also tested for functional antagonism using
合成了3-芳基-4-羟基喹啉-2(1H)-one的一系列5-,6-,7-和8-氮杂类似物,并测定为NMDA /甘氨酸受体拮抗剂。这些拮抗剂的体外效能是通过在大鼠大脑皮膜中置换甘氨酸位点放射性配体[[(3)H] 5,7-dicholorokynurenic酸([(3)H] DCKA)确定的。还使用表达克隆的NMDA受体(NR)1A / 2C亚基的非洲爪蟾卵母细胞中的电生理测定法测试了所选化合物的功能拮抗作用。在研究的5、6、7、8氮杂-3-芳基-4-羟基喹啉2(1H)-中,5-氮杂7-氯-4-羟基-3-(3-苯氧基苯基) )quinolin-2-(1H)-one(13i)是最有效的拮抗剂,在[(3)H] DCKA结合中的IC(50)值为110 nM,在电生理学中的K(b)为11 nM分析。
