7,4'-Dihydroxyflavone 是 eotaxin/CCL11 和 CBR1 抑制剂 (IC50=0.28 μM)，抑制嗜酸性粒细胞趋化因子产生。7,4'-Dihydroxyflavone 通过调节 NF-κB，STAT6 和 HDAC2 抑制 MUC5A 基因表达和粘液产生。7,4'-Dihydroxyflavone 降低 (PMA) 刺激的 NCI-H292 细胞 MUC5AC 表达，IC50 值为 1.4 μM。 7,4'-Dihydroxyflavone is eotaxin/CCL11 inhibitor and CBR1 inhibitor (IC50=0.28 μM). 7,4'-Dihydroxyflavone has the ability to consistently suppress eotaxin production and prevent dexamethasone (Dex)‐paradoxical adverse effects on eotaxin production[1]. 7,4'-Dihydroxyflavone (7,4'-DHF) inhibits MUC5AC gene expression, mucus production and secretion via regulation of NF-κB, STAT6 and HDAC2.7,4'-Dihydroxyflavone (7,4'-DHF) decreases phorbol 12-myristate 13-acetate (PMA) stimulated NCI-H292 human airway epithelial cell MUC5AC gene expression and mucus production with IC50 value of 1.4 µM.
