Quinoxalin-2(1H)-one based design and synthesis produced several series of aldose reductase (ALR2) inhibitor candidates. In particular, phenolic structure was installed in the compounds for the combination of antioxidant activity and strengthening the ability to fight against diabetic complications. Most of the series 6 showed potent and selective effects on ALR2 inhibition with IC50 values in the
基于喹喔啉2(1 H)-one的设计和合成产生了多个系列的醛糖还原酶(ALR2)抑制剂候选物。特别地,在化合物中安装了酚结构,以结合抗氧化活性和增强抵抗糖尿病并发症的能力。系列6的大多数显示出对ALR2抑制的有效和选择性作用,IC 50值在0.032–0.468μM的范围内,而2-(3-(2,4-二羟基苯基)-7-氟-2-氧代喹喔啉-1( 2 H)-基)乙酸(6e)最活跃。更重要的是,大多数系列8不仅显示出对ALR2抑制的良好活性,而且还显示出强大的抗氧化活性,并且2-(3-(3-甲氧基-4-羟基苯乙烯基)-2-氧代喹喔啉-1(2 H)-基)乙酸(8d)均匀与众所周知的抗氧化剂Trolox一样强,浓度为100μM,证明C3 p-羟基苯乙烯基侧链是缓解氧化应激的关键结构。因此,这些结果表明获得了既具有抑制ALR2作用又具有抗氧化剂作用的多功能ALR2抑制剂。
