OBJECTIVES Eugenol, obtained from clove oil (Eugenia caryophyllata), possess several biological activities. It is anti-inflammatory, analgesic, anaesthesic, antipyretic, antiplatelet, anti-anaphylactic, anticonvulsant, anti-oxidant, antibacterial, antidepressant, antifungal and antiviral. The anti-oxidant activity of eugenol have already been proven. From this perspective testing, a series of planned
目的丁香油(从丁香油(Eugenia caryophyllata)获得)具有多种生物学活性。它具有抗炎,止痛,镇痛,解热,抗血小板,抗过敏,抗惊厥,抗氧化,抗菌,抗抑郁,抗真菌和抗病毒作用。丁子香酚的抗氧化活性已被证实。从这个角度进行测试,筛选了一系列丁香酚的计划结构衍生物,以进行结构优化并因此提高了这些生物活性的效力。方法为了增加结构变异性,通过酚羟基的酰化和烷基化合成了16种化合物。抗氧化活性是基于捕获DPPH自由基(2,2-二苯基-1-吡啶基-肼基),ABTS自由基2,2' -叠氮基双(3-乙基苯并噻唑啉-6-磺酸),TBARS(硫代巴比妥酸反应性物种),总巯基和羰基含量(丁香酚衍生物的终浓度范围为50至200μm)。主要发现四种衍生物表现出有效的浓度,可降低50%的DPPH自由基(EC50)<100μm,具有作为自由基清除剂的良好潜力。这些化合物中的三种还显示出ABTS自由基的减少
