According to a study published by "Journal of ethnopharmacology", the ethanolic extract of Myrsine seguinii inhibits the production of nitric oxide (NO) and prostaglandin (PG)E2 in RAW264.7 cells and peritoneal macrophages stimulated by LPS. This extract suppresses the mRNA expression of the inducible NO synthase (iNOS) and cyclooxygenase (COX)-2 genes by down-regulating the activation of nuclear factor (NF)-κB and activator protein (AP-1). Ms-EE can directly suppress the enzyme activities of Syk, Src, and interleukin-1 receptor-associated kinase-1 (IRAK-1). Orally administered Ms-EE also inhibits the phosphorylation of Src and Syk in peritoneal exudate-derived cells prepared from peritonitis. The plant contains quercetin as a major active component that suppresses the release of inflammatory mediators NO and PGE2 and the enzyme activities of Src, Syk, and IRAK-1.
