quinoxalinone derivatives were synthesized and tested for their inhibitory activity against aldose reductase. Among them, N1-acetate derivatives had significant activity in a range of IC50 values from low micromolar to submicromolar, and compound 15a bearing a C3-phenethyl side chain was identified as the most potent inhibitor with an IC50 value of 0.143 μM. The structure–activity studies suggested that
合成了新的喹喔啉酮衍生物,并测试了其对醛糖还原酶的抑制活性。其中,N1-乙酸酯衍生物在从低微摩尔到亚微摩尔的IC 50值范围内具有显着活性,并且带有C3-苯乙基侧链的化合物15a被确定为最有效的抑制剂,IC 50值为0.143μM。结构活性研究表明,C3-苯乙基和C6-NO 2基团在增强基于喹喔啉酮的抑制剂的活性和选择性方面都起着重要作用。
