Astragalin是与氧化酶相关的eotaxin-1、PKCβ2磷酸化、NF-κB/MAPK激活和PLCγ1的抑制剂,以剂量依赖的方式起作用[1][2]。
氧化应激意味着细胞的正常氧化还原状态发生扰动,通过产生可破坏细胞内部所有部件的过氧化物和自由基,引起毒性反应。据报道,氧化应激可导致细胞信号正常机理的破坏,如癌症发展、帕金森病、阿尔兹海默症、动脉粥样硬化、被动皮肤反应、炎症反应、心脏衰竭、心肌梗死、镰状细胞病、感染和慢性疲劳综合症[1,3]。在人类骨性关节炎软骨细胞中,astragalin可抑制NF-κB和MAPK激活[2]。
Astragalin具有抗氧化能力。在人类嗜碱性细胞系KU812中,口服astragalin可抑制组胺分泌和被动皮肤反应[4]。在气管上皮BEAS-2B细胞中,astragalin处理可拮抗内毒素诱导的会造成气道功能障碍和炎症的氧化应激[1]。
在NC/Nga特应性皮炎小鼠模型中,astragalin处理可显著抑制皮炎发展、抓挠行为和血清IgE升高[4]。
