3-hydroxy-1H-pyrrole-2,5-dione derivatives has been prepared and studied as inhibitors of glycolic acid oxidase (GAO). Compounds possessing large lipophilic 4-substituents are, in general, potent, competitive inhibitors of porcine liver GAO in vitro. Methylation of the nitrogen or the 3-hydroxy substituent reduced potency dramatically, indicating the requirement for the two acidic functions on the 1H-pyrrole-2
已经制备了一系列广泛的新颖的4-取代的3-羟基-1H-吡咯-2,5-二酮衍生物,并作为乙醇酸氧化酶(GAO)的抑制剂进行了研究。具有大的亲脂性4-取代基的化合物通常是猪肝GAO体外的有效竞争性抑制剂。氮或3-羟基取代基的甲基化显着降低了效能,表明需要1H-吡咯-2,5-二酮核上的两个酸性功能。在大鼠肝脏灌注研究中,使用三种代表性化合物,观察到浓度依赖性抑制[1-14C]乙醇酸酯向[14C]草酸酯的转化。长期口服喂食乙二醇的大鼠4-(4'-溴[1,1'-联苯] -4-基)衍生物(83)在58天内可显着降低草酸尿水平期。
