Anti-inflammatory activity of hydroxycinnamic acid derivatives isolated from corn bran in lipopolysaccharide-stimulated Raw 264.7 macrophages

► The EECB inhibited LPS-induced NO production and iNOS expression. ► DFP showed the most potent inhibition on NO production. ► The four HADs significantly reduced the LPS-induced increase in NF-κB promoter activity. ► Phenolic amides in the corn bran may be a potential source of natural anti-inflammatory agents.
