Abstract
Weigela subsessilis is used in folk medicine to treat pain and allergic syndromes in Korea. However, the antibacterial and anti-inflammatory activities of W. subsessilis callus extract remain unexplored. In this study, we aimed to evaluate the W. subsessilis callus of pharmacological activity. Therefore, we first established in vitro calluses of W.subsessilis via plant tissue culture methods. We then evaluated the antioxidant and anti-inflammatory effects of W. subsessilis callus extract in lipopolysaccharide (LPS)-treated RAW264.7 macrophage cells. The W. subsessilis callus extract showed antioxidant and anti-inflammatory effects. These effects were regulated via suppression of mitogen-activated protein kinase signaling through LPS-induced translocation of nuclear factor kappa B (NF-κB) p65 from the cytoplasm to the nucleus. W. subsessilis callus extract also showed antibacterial and anti-inflammatory activities in Propionibacterium acnes-treated HaCaT keratinocyte cells. These results indicate that W. subsessilis callus extract has antioxidant, antibacterial and anti-inflammatory activities, suggesting its possible application in the treatment of inflammatory disorders.
