一般描述
β-萘黄酮是一种多环芳烃。
应用
β-萘黄酮已用于：
- 作为芳烃受体激动剂，阐明其对转基因细胞色素 P450 1A1（cyp1a）报告基因的斑马鱼胚胎中 Cyp1A1 表达的影响
- 作为 AhR 激动剂，处理原代正常人表皮角质形成细胞（NHEKs），通过蛋白质印迹法研究芳香烃受体（AhR）激活
- 确定其对肌营养不良蛋白（Dp）71 表达的影响
- 刺激 Cre 重组酶的表达，并删除侧翼为 loxP 序列的等位基因
生化/生理作用
β-萘黄酮是人体中芳烃受体（AhR）的外源配体。它是 I 期解毒酶（CYP）和 II 期酶（UDP-GTs）和 NAD(P)H 依赖性醌氧还原酶-1（NQO1）的诱导物。它还诱导细胞色素 P450（Cyp1a）的表达。BNF 通过改变转录因子的结合来抑制 Duchenne 肌营养不良基因（肌营养不良蛋白（Dp）71） 的表达。
