Abstract
|
|
|
|
Kava (Piper methysticum, P. methysticum) is used as traditional herbal medicine for urogenital diseases, rheumatisms, gastrointestinal problems, respiratory irritations, and pulmonary pains. We identified a flavokavain C (FKC) from P. methysticum, which showed anti-inflammatory activity on nuclear factor κB (NF-κB)-dependent nitric oxide (NO) production and expression of inducible nitric oxide synthase (iNOS) in lipopolysaccharide (LPS)-induced RAW264.7 macrophages. FKC inhibited accumulation of reactive oxygen species (ROS), such as hydrogen peroxide, and was able to dose-dependently reduce the LPS-induced NO production and the expression of various inflammation- associated genes (iNOS, IL-1β, IL-6) through inhibition of NF-κB and MAPKs (ERK and JNK). In conclusion, these results indicate that FKC may have the potential to prevent inflammation process including NF-κB and MAPKs pathways, and it could be applicable to functional cosmetics for anti-inflammation and antioxidant properties.
