2(3H)-Benzoxazolone derivatives are versatile heterocyclic compounds since they display a wide range of pharmacological properties. On the other hand, anilide pharmacophore has been known in medicinal chemistry as an useful template in various pharmacological states. In this study, we synthesized eleven 5-chloro-2(3H)-benzoxazolone-3-alkananilide derivatives and evaluated their antioxidant activities. The structural confirmation of the title compounds was achieved by spectral and analytical data. The antioxidant capacity of the synthesized compounds was determined by the 2,2-diphenyl-2-picrylhydrazyl hydrate (DPPH) and 2,2-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radicals scavenging assays. The results indicated that the majority of the compounds were effective in both tests. The most active compound in the series was compound 6, bearing 4-methoxy substituent on the N-phenyl ring of the propionanilide skeleton.
2(3H)-苯并恶唑酮衍生物是用途广泛的杂环化合物,因为它们表现出广泛的药理学特性。另一方面,苯胺药效基团在药物化学中被认为是各种药理状态下的有用模板。在这项研究中,我们合成了11种5-氯-2(3H)-苯并恶唑酮-3-烷酰苯胺衍生物并评估了它们的抗氧化活性。通过光谱和分析数据确认了标题化合物的结构。通过2,2-二苯基-2-三硝基苯肼水合物(DPPH)和2,2-偶氮双(3-乙基苯并噻唑啉-6-磺酸)(ABTS)自由基清除试验测定了合成化合物的抗氧化能力。结果表明大多数化合物在两项测试中均有效。该系列中最活跃的化合物是化合物6,其丙酰苯胺骨架的N-苯环上带有4-甲氧基取代基。
