To widen aurones applicability in achromatic food and cosmetic applications, a series of dihydroaurones were designed to mimic natural aurones as well as synthetic aurones. Dihydroaurones have been synthesized from the corresponding aurones by hydrogenation. These dihydroaurones and their corresponding aurones were screened for antioxidant, anti-inflammatory and tyrosinase enzyme inhibitory activity. Synthesized dihydroaurones (3b-f) displayed superior antioxidant activity in superoxide free radical scavenging assay than the standard gallic acid. Dihydroaurones (3b-f) also exhibited significant tyrosinase enzyme inhibitory activity and two dihydroaurones (3h, 3j) showed promising 5-lipoxygenase inhibitory activity.
为了扩大奥罗宁在无色食品和化妆品应用中的适用性,设计了一系列二氢奥罗宁,以模拟天然奥罗宁和合成奥罗宁。通过氢化反应从相应的奥罗宁合成了这些二氢奥罗宁。对这些二氢奥罗宁及其对应的奥罗宁进行了抗氧化、抗炎和酪氨酸酶抑制活性的筛选。合成的二氢奥罗宁(3b-f)在超氧自由基清除实验中表现出比标准的没食子酸更优越的抗氧化活性。二氢奥罗宁(3b-f)还表现出显著的酪氨酸酶抑制活性,其中两种二氢奥罗宁(3h、3j)显示出有希望的5-脂氧酶抑制活性。
