Avenanthramide-C methyl ester is an inhibitor of NF-κB activation that acts by blocking the phosphorylation of IKK and IκB (IC₅₀ ~ 40 μM).¹ Through this mechanism, avenanthramide-C methyl ester dose dependently inhibits the expression and secretion of IL-6, IL-8, and MCP-1 in human aortic endothelial cells. ¹

Avenanthramide-C methyl ester is an anti-inflammatory agent and NF-κB inhibitor that inhibits the secretion of pro-inflammatory factors. Avenanthramide-C methyl ester inhibits NF-κB activation by inhibiting IKK and IκB phosphorylation and inhibiting proteasome activity[1].
