due to its suspected role as a human carcino- gen, based on testing in mice, 5-6 the need has arisen to develop an analogue with similar biological properties. With the goal of finding a new analogue of caffeic acid, we previously reported the synthesis of 1-hydroxy-2-pyridone analogues of caffeic acid by the application of bioisosterism and the evaluation of their antioxidant activities. 7
1-2 在天然抗氧化剂中,存在于水果、蔬菜、葡萄酒、橄榄油和咖啡豆等多种农产品中的咖啡酸具有多种机制,包括自由基清除、金属离子螯合和对特定酶的抑制作用会诱发自由基。3-4 然而,由于咖啡酸不被批准直接用于食品中,由于其怀疑是人类致癌物,基于在小鼠中的测试,5-6 需要开发具有相似生物学特性的类似物. 为了找到一种新的咖啡酸类似物,我们之前报道了通过应用生物等排性合成咖啡酸的 1-羟基-2-吡啶酮类似物并评估其抗氧化活性。7
