- The inflammatory bowel diseases (IBD) including ulcerative colitis and Crohn disease are characterized by chronic inflammation throughout the gastrointestinal tract. The prevalence of IBD has been increasing worldwide, and has sometimes led to irreversible impairment of gastrointestinal structure and functions. In the present study, we identified a new sulfoquinovosylmonoacylglycerols (SQMG) (1) together with two known SQMGs (2 and 3) regulating intestinal inflammation from the brown alga Turbinaria ornata. The anti-inflammatory properties of two bioactive SQMGs, 1 and 2 were evaluated using an in vitro co-culture system consisting of human epithelial Caco-2 cells and PMA (phorbol 12-myristate 12-acetate)-differentiated THP-1 macrophages. Treatment with 1 or 2 inhibited the production nitric oxide and prostaglandin E-2 induced by lipopolysaccharide and interferon gamma challenge. The expressions of inducible nitric oxide synthase and cyclooxygenase 2 were markedly down-regulated in response to inhibition of nuclear factor kappa B translocation to nucleus. These findings suggest the potential use of the brown alga T. ornata and its biologically active metabolites SQMGs as pharmaceutical adjuvants in the treatment of inflammation-related diseases, including IBD.
