Periodontitis, a chronic inflammatory periodontal disease that develops from gingivitis, is caused by periodontal pathogenic bacteria such as Porphyromonas gingivalis. Recent studies have focused on the antioxidant, anti-human immunodeficiency virus, anticarcinogenic, and anti-inflammatory properties of gomisins. However, the anti-inflammatory activities of gomisin plants through heme oxygenase-1 (HO-1) signals remain poorly defined. We found that gomisins' anti-inflammatory activity occurs via the induction of HO-1 expression. Gomisins G and J inhibit the production of the pro-inflammatory cytokines tumor necrosis factor-α, interleukin-1β, and interleukin-6 and also block nuclear factor-κB activation in Raw264.7 cells stimulated with P. gingivalis lipopolysaccharide. Furthermore, pro-inflammatory cytokine production is inhibited through the induction of HO-1 expression. HO-1 expression is induced by all gomisins, but their anti-inflammatory activity via HO-1 signaling is observed with gomisins G and J, and not A. We found that gomisins G and J extracted from Schisandria chinensis can inhibit the P. gingivalis lipopolysaccharide induced-inflammatory responses in Raw264.7 cells.
