limitation, novel series of 3,4-dihydroquinolin-2(1H)-one derivatives as dual inhibitor targeting AKR1B1/ROS (Reactive Oxygen Species) were designed and synthesized. Most of these derivatives were found to be potent and selective against AKR1B1, and compound 8a was the most active with an IC50 value of 0.035 μM. Moreover, some prepared derivatives showed strong anti-ROS activity, and among them the phenolic
AKR1B1(醛糖还原酶)已被用作治疗糖尿病并发症的治疗靶标,已有50多年的历史,最近更被用于炎症和癌症。但是,大多数开发的小分子抑制剂具有生物活性低的缺陷。为了解决这个限制,设计并合成了一系列新型的3,4-二氢喹啉-2(1 H)-one衍生物作为靶向AKR1B1 / ROS(活性氧)的双重抑制剂。发现这些衍生物大多数对AKR1B1具有强效和选择性,化合物8a的活性最高,IC 50值为0.035μM 。此外,一些制备的衍生物显示出很强的抗ROS活性,其中包括酚类3,5-二羟基化合物8b被证明是最有效的,甚至与浓度为100μM的著名抗氧化剂Trolox相当。因此,结果提示成功构建了用于AKR1B1 / ROS治疗靶标的有效双重抑制剂。
