title: 1'S-1'-Acetoxychavicol acetate as a new type inhibitor of interferon-beta production in lipopolysaccharide-activated mouse peritoneal macrophages.
abstract: 1'S-1'-Acetoxychavicol acetate from the rhizomes of Alpinia galanga was known to show potent inhibitory effect on the production of nitric oxide (NO) in lipopolysaccharide-activated mouse peritoneal macrophages. To clarify its mechanism of action, the effects of 1'S-1'-acetoxychavicol acetate on the expression of interferon-beta (IFN-beta) mRNA and activation of nuclear factor-kappaB (NF-kappaB), both of which participate in the induction of inducible NO synthase, were examined in lipopolysaccharide-activated macrophages. The results were compared with those of two inhibitors of the NF-kappaB activation, costunolide and caffeic acid phenethyl ester. 1'S-1'-Acetoxychavicol acetate inhibited IFN-beta mRNA expression as well as NF-kappaB activation, and two related compounds, (+/-)-1-acetoxy-1-(2-acetoxyphenyl)-2-propene and (+/-)-1-acetoxy-1-(4-acetoxyphenol)-3-butene, also inhibited IFN-beta mRNA expression. In addition, 1'S-1'-acetoxychavicol acetate inhibited the production of NO stimulated by poly(I:C) via Toll-like receptor 3.
