• Desmarestia viridis
• Dictyopteris divaricata
• Scytosiphon lomentaria
• Ishige okamurae
• inducible nitric oxide synthase (iNOS)
• interlukin-1 beta
• cyclooxygenase (COX)-2
• I kappa B
• proinflammatory cytokine
• anti-inflammation

The effect of 4 seaweed extracts (Desmarestia viridis, Dictyopteris divaricata, Scytosiphon lomentaria, and Ishige okamurae) on pro-inflammatory mediators as well as nuclear factor (NF)-kappa B in the stimulated Raw 264.7 cells was investigated. They reduced iNOS and interlukin (IL)-1 beta expressions at transcription level. Of those, 3 extracts (D. divaricata, I. okamurae, and S. lomentaria) inhibited the COX-2 expression at translation level. I kappa B-alpha degradation was inhibited by D. divaricata and S. lomentaria extracts. Therefore, we concluded that the extracts from D. divaricata and S. lomentaria could inhibit the activation of murine macrophage through the blocking of NF-kappa B activation.
