ethanol and characterized by spectral (FTIR, 1H NMR, and Mass) analysis. Compound 4a was effective in scavenging the DPPH radicals (57%) and nitric oxide (NO) radicals (52%) while compound 4e was able to significantly neutralize ABTS cation radicals (58%). However, the radical scavenging ability was lesser compared to the standard antioxidant agents. Among the tested compounds, 4f and 4g elicited good antinociceptive
使用苯氧基乙酰肼和各种酰氯(苯甲酰基、金刚羰基肉桂酰基、4-氯苯甲酰氯)或碱(哌啶、吗啉和取代哌啶酮)通过酰胺化合成了一系列新型苯氧基乙酰甲酰胺(4a-4g),并对其进行了评价抗氧化和抗伤害活性。通过使用乙醇重结晶来纯化标题化合物并通过光谱(FTIR、1H NMR和质谱)分析来表征。化合物4a能有效清除DPPH自由基(57%)和一氧化氮(NO)自由基(52%),而化合物4e能够显着中和ABTS阳离子自由基(58%)。然而,与标准抗氧化剂相比,自由基清除能力较差。在测试的化合物中,4f 和 4g 在中枢和外周动物模型(25 mg/kg 体重)中引发了良好的抗伤害活性。化合物 4b 和 4f 似乎会打开 ATP 敏感钾通道(KATP 通道),这是其外周作用的可能机制。羧酰胺与单甘油酯脂肪酶 (MAGL) 良好结合,并在活性位点建立强相互作用。
