Bioactive compounds from liverworts: Inhibition of lipopolysaccharide-induced inducible NOS mRNA in RAW 264.7 cells by herbertenoids and cuparenoids

Abstract

The inhibition of lipopolysaccharide (LPS)-induced inducible nitric oxide synthase (iNOS) by herbertenoids and cuparenoids isolated from liverworts in RAW 264.7 macrophages was evaluated. Among compounds tested, herbertenediol, cuparenediol, 1,2-diacetoxyherbertene and 2-hydroxy-4-methoxycuparene exhibited significant activity. For 2-hydroxy-4-methoxycuparene, chosen as representative compound, the strong inhibitory activity was related to the inhibition on LPS-induced iNOS mRNA. The structure-activity relationship will be discussed.
