ABSTRACT
OBJECTIVES:
Artemisia scoparia Waldst. et Kit. (AS) has been used to treat inflammation, urticaria and hepatitis. However, the scientific studies of AS and its active compound for inflammatory reactions in activated human mast cell line, HMC-1 cells have not yet been elucidated. MATERIALS ANDMETHODS:
Here, we isolated 3,5-dicaffeoyl-epi-quinic acid (DEQA) from AS butanol fraction. The anti-inflammatory effect of AS and its new active compound, DEQA was examined in HMC-1 cells by studying the following markers phorbol 12-myristate 13-acetate and calcium ionophore A23187 (PMACI)-induced thymic stromal lymphopoietin (TSLP), tumor necrosis factor (TNF)-α, interleukin (IL)-1ß and IL-6 secretion and mRNA expression by ELISA and RT-PCR, respectively. Furthermore, mechanism related to anti-inflammatory was examined by Western blotting.RESULTS:
We reported that AS and its new active compound, DEQA significantly reduced TSLP, TNF-α, IL-1ß and IL-6 production levels through the reduction of caspase-1 activity. The mRNA expression of these inflammatory cytokine was also reduced via blocking nuclear factor-κB nuclear translocation by AS and DEQA. In addition, AS significantly reduced phosphorylated-c-Jun N-terminal kinase level and DEQA significantly reduced both phosphorylated-c-Jun N-terminal kinase and -p38 mitogen-activated protein kinase levels.CONCLUSIONS:
Therefore, these results indicated that AS and its active compound, DEQA may improve mast cell-mediated inflammatory diseases.Key words
