Myrrh is a resinous substance obtained from Commiphora trees, which has long been used as an antiseptic agent. A sesquiterpene, $1{\beta}$, $6{\alpha}$-dihydroxyeudesm-4(15)-ene (DE), was isolated from the hot water extract of Myrrh. In the present study, we found that DE attenuates the lipopolysaccharide (LPS)-induced inflammation in BV2 microglial cells. DE significantly inhibited LPS-induced production of pro-inflammatory mediators such as nitric oxide (NO) and prostaglandin $E_2$ ($PGE_2$) in BV2 microglia in a concentration-dependent manner without cytotoxic effect. Furthermore, DE dose-dependently suppressed the protein expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2). These results suggest that DE may be a good candidate to regulate LPS-induced inflammatory response.
