4',7-Dihydroxyflavone

7,4'-Dihydroxyflavone (7,4'-DHF) is a flavonoid isolated from Glycyrrhiza uralensis, the eotaxin/CCL11 inhibitor, 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[1].
