Anti-Neuroinflammatory Effects of a Representative Low-Molecular-Weight Component Isolated from Codium fragile Through Inhibition of the NF-κB Pathway in Microglia and Macrophage Cells

Year: 2026

Type: article

Abstract: The worldwide incidence of neurodegenerative diseases (ND), such as dementia, has increased, and neuroinflammation is considered a crucial factor in the development of ND. Codium fragile is considered ocean waste in many countries; however, some countries, including Korea, consume it as a food resource. In this study, a major low-molecular-weight component and chemical marker, uracil, was isolated from the aqueous extracts of C. fragile (AECF); additionally, its content was measured through HPLC quantitative analysis. AECF and uracil were examined for their anti-inflammatory activities against lipopolysaccharide (LPS)-stimulated BV2 microglia and RAW264.7 macrophage cell lines under inflammation conditions. The results showed that AECF and uracil inhibited the production of pro-inflammatory cytokines by suppressing the NF-κB pathway.
