Chicanine has anti-inflammatory activity in macrophages by down-regulating LPS-induced inflammatory cytokines in IκBα±/MAPK/ERK signaling pathways.

In this study, Chicanine, one of the major lignan compounds of S. chinesis, was investigated for suppressive effects on lipopolysaccharide (LPS)-induced inflammatory responses in murine macrophages (RAW 264.7 cells). Chicanine was found to have anti-inflammatory properties with the inhibition of nitric oxide (NO) and Prostaglandin E (2) (PGE2) production and nuclear factor-κB (NF-κB) signaling in LPS-stimulated RAW 264.7 cells with no cytotoxic effects. Treatment of RAW 264.7 cells with Chicanine down-regulated LPS-induced expression of pro-inflammatory cytokines including TNFα±, IL-1β, MCP-1, G-CSF, cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS). These inhibitory effects were found with the blockage of p38 mitogen-activated protein kinase (MAPK), extracellular signal-regulated kinases 1 and 2 (ERK 1/2), and also IκB-α± phosphorylation[1]
