three new kynurenine analogues, and their evaluation as inhibitors of kynureninase and kynurenine-3-hydroxylase are reported. The most potent of these compounds, m-NBA, has an IC50 of 0.9 +/- 0.1 microM as an inhibitor of kynurenine-3-hydroxylase and of 100 +/- 12 microM as an inhibitor of kynureninase. When administered to rats, m-NBA significantly increases the concentration of kynurenine and kynurenic
(o-硝基苯甲酰基)-,(间硝基苯甲酰基)-和(对硝基苯甲酰基)丙氨酸(邻-,间-和p-NBA),三种新的犬尿氨酸类似物的合成及其作为犬尿氨酸酶和尿囊素抑制剂的评估报告了犬尿氨酸-3-羟化酶。这些化合物中最有效的化合物m-NBA,作为犬尿氨酸3-羟化酶的抑制剂的IC50为0.9 +/- 0.1 microM,作为犬尿氨酸酶的抑制剂的IC50为100 +/- 12 microM。当对大鼠给药时,m-NBA会显着增加大脑以及血液和肝脏中犬尿氨酸和犬尿酸的浓度。m-NBA还被证明可以增加海马细胞外液中犬尿酸的浓度。这种增加与镇静和抗惊厥活动有关,
