A series of 5-azaquinoxaline-2,3-dione derivatives were synthesized and evaluated on d-amino acid oxidase (DAAO) inhibition as potential α-hydroxylactam-based inhibitors. The potent inhibitory activities in vitro suggested that 5-nitrogen could significantly enhance the binding affinity by strengthening relevant hydrogen bond interactions. The analgesic effects of intrathecal and systemic injection
合成了一系列5-氮杂喹喔啉-2,3-二酮衍生物,并评估了其作为潜在的基于α-羟基内酰胺的抑制剂对d-氨基酸氧化酶(DAAO)的抑制作用。体外的强抑制活性表明5-氮可以通过增强相关的氢键相互作用来显着增强结合亲和力。研究了鞘内和全身注射8-氯-1,4-二氢吡啶并[2,3- b ]吡嗪-2,3-二酮(5-氮杂喹喔啉-2,3-二酮的代表分子)的镇痛作用。啮齿动物。这项研究不仅证实了DAAO抑制剂的镇痛作用,而且还提供了一类具有口服应用潜力的新型化学实体,可用于治疗慢性疼痛和吗啡镇痛耐受性。
