Batillaria multiformis (B. multiformis) belong to gastropods. They live generally in the sandpit of the lagoons and the estuaries of the intertidal zone. Most of them are distributed in Korea, Japan and China. In this study, we investigated the anti-inflammatory potential of B. multiformis water extracts (BMW). The results showed that the extracts significantly decreased the production of nitric oxide (NO) and pro-inflammatory cytokines, including tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in LPS-induced RAW 264.7 macrophages. In addition, the extracts suppressed the protein levels of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in a dose dependent manner. Further investigation indicated that BMW suppressed phosphorylated c-Jun N-terminal kinase (JNK), extracellular regulated protein kinase (ERK) and p38 through the MAPK signaling pathway and influenced the NF-κB signaling pathway by suppressing the IκBα degradation in LPS-induced RAW 264.7 macrophages.
