New N-substituted oxime derivatives (5b, 5d-g, 5i-k, and 5m) and known compounds (5a, 5c, 5h, 5g, 5l, and 5n-q) were obtained by reacting phenyl and butyl oxime chloride analogs with aniline, piperazine derivatives, piperidine, and diethylamine. Structures of all new compounds were determined by 1H NMR, 13C NMR, HRMS, and FTIR methods. All compounds were evaluated in vitro for their antiradical activity
通过使苯基和丁基肟氯化物类似物与苯胺、哌嗪衍生物、哌啶和二乙胺。所有新化合物的结构均通过1 H NMR、13 C NMR、HRMS 和 FTIR 方法确定。所有化合物都在体外评估了它们的抗自由基活性和过氧化氢清除活性。化合物 5g、5h、5i、5j、5k、5l、5m 和 5p 具有良好的抗自由基活性,EC 50值 < 1(浓度抗自由基 (µM)/浓度 DPPH (µM))。在过氧化物清除活性测试中获得了类似的结果。这些结果表明哌啶和丁基取代大大增加了肟的抗自由基活性。发现化合物 5l 和 5m 是最好的自由基清除剂。此外,还针对 CP450 (CYP1A2)、NADPH 氧化酶和黄嘌呤氧化酶对化合物 (5a-q) 进行了分子对接研究,以通过产生 ROS 的酶抑制来预测它们的抗氧化能力。
