acid amides and 4-hydroxycinnamamides were synthesized and their antioxidant and neuroprotective activities were evaluated. Among the prepared compounds, 8b, and exhibited potent inhibition of lipid peroxidation in rat brain homogenates, and marked DPPH radical scavenging activities. Furthermore, and exhibited neuroprotective action against the oxidative damage induced by the exposure of primary cultured
合成了4-羟基苯基乙酸酰胺和4-羟基肉桂酰胺,并评估了它们的抗氧化和神经保护活性。在制备的化合物中,8b在大鼠脑匀浆中显示出对脂质过氧化的有效抑制作用,并具有明显的DPPH自由基清除活性。此外,并表现出针对主要培养的大鼠皮层细胞暴露于H(2)O(2),黄嘌呤/黄嘌呤氧化酶或Fe(2 +)/抗坏血酸引起的氧化损伤的神经保护作用。根据这些结果,我们发现它是所测试化合物中最有效的抗氧化剂。
