AbstractBackground: Fucoxanthin (FX), a xanthophyll pigment which occurs in marine brown algae with remarkable biological properties, has been proven to be safe for consumption by animals. Although FX has various pharmacological effects including anti-inflammatory, anti-tumor, anti-obesity, antioxidant, anti-diabetic, anti-malarial, and anti-lipid, in vivo protective effect against sepsis has not been reported. In this study, we aimed at evaluation the efficacy of the FX in a model of sepsis mouse. Methods: FX was successfully isolated from Conticribra weissflogii ND-8 for the first time. The FX was identified by thin-layer chromatography (TLC), high-performance liquid chromatography-mass spectrometry (HPLC-MS), and nuclear magnetic resonance (NMR). Animals were randomly divided into 9 groups, including Sham group (mouse received an intraperitoneal injection of normal saline 1.0 ml/kg), FX-treated (0.1-1.0 ml/kg), Lipopolysaccharide (LPS)-treated (20 mg/kg), FX+LPS-treated (0.1-10.0 mg/kg and 20 mg/kg, respectively), and urinastatin groups (10(4) U/kg). Nuclear factor (NF)-kappa B activation could be potential treatment for sepsis. NF-kappa B signaling components were determined by western-blotting. IL-6, IL-1 beta, TNF-alpha production, and NF-kappa B activation were evaluated by ELISA and immunofluorescent staining in vitro. Results: FX was found to decrease the expression of inflammatory cytokines including IL-6, IL-1 beta, and TNF-alpha, in a prophylactic manner in the LPS-induced sepsis mouse model. Meanwhile, FX significantly inhibits phosphorylation of the NF-kappa B signaling pathway induced by LPS at the cellular level and reduces the nuclear translocation of NF-kappa B. The IC50 for suppressing the expression of NF-kappa B was 11.08 +/- 0.78 mu M in the THP1-Lucia (TM) NF-kappa B cells. Furthermore, FX also inhibits the expression of inflammatory factors in a dose-dependent manner with the IC50 inhibition of IL-6 production was 2.19 +/- 0.70 mu M in Raw267.4 macrophage cells. It is likely that the molecules with the ability of targeting NF-kappa B activation and inflammasome assembly, such as fucoxanthin, are interesting subjects to be used for treating sepsis.
