Summary:The aim of this study was to investigate the synergistic anti-inflammatory effect of rosmarinic acid (RA) and luteolin from perilla (Perilla frutescens L.) leaves in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. A combination of RA and luteolin more strongly inhibited the production of nitric oxide (NO), inducible NOS (iNOS), prostaglandin $E_2$ ($PGE_2$), and COX-2 than higher concentrations of RA or luteolin alone in LPS-stimulated RAW264.7 macrophages. The combined RA and luteolin synergistically inhibited the production of pro-inflammatory cytokines, such as tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin-6 (IL-6), and interleukin-$1{\beta}$ (IL-$1{\beta}$), in LPS-stimulated RAW264.7 macrophages. Furthermore, combined RA and luteolin more strongly suppressed NF-${\kappa}B$ activation than RA or luteolin alone, by inhibiting the degradation of inhibitor of NF-${\kappa}B(I{\kappa}B)$-${\alpha}$ and nuclear translocation of the p65 subunit of NF-${\kappa}B$ in LPS-stimulated RAW264.7 macrophages. Collectively, these results suggest that RA and luteolin in combination exhibit synergistic effects in suppression of LPS-induced inflammation in RAW264.7 macrophages. 본 연구에서는 들깨 유래 기능성 물질인 rosmarinic acid (RA)와 luteolin이 RAW264.7 세포에서 항염증작용에 대한 상승 효과가 있는지 알아보고자 하였다. 그 결과 RAW264.7 세포에 RA($50{\mu}M$)와 luteolin ($1{\mu}M$)을 동시에 처리하였을 경우 염증 매개인자인 NO, iNOS, $PGE_2$, COX-2의 생성을 RA ($100{\mu}M$)와 luteolin ($2{\mu}M$)을 각각 처리하였을 때 보다 더 뛰어나게 억제하였다. 또한 RA ($50{\mu}M$)와 luteolin ($1{\mu}M$)을 동시에 처리하였을 경우 TNF-${\alpha}$, IL-6, IL-$1{\beta}$ 같은 염증성 사이토카인의 생성량을 RA ($100{\mu}M$)와 luteolin ($2{\mu}M$)을 각각 처리하였을 때 보다 더 뛰어나게 억제하는 것을 확인하였다. 그리고 RA ($50{\mu}M$)와 luteolin ($1{\mu}M$)을 동시에 처리하였을 경우 RA ($100{\mu}M$)와 luteolin ($2{\mu}M$)을 각각 처리하였을 때 보다 NF-${\kappa}B$의 subunit인 p65의 translocation과 $I{\kappa}B$-${\alpha}$의 degradation을 더 뛰어나게 억제하는 것을 볼 수 있어 두 화합물 간의 상승작용이 뚜렷함을 확인 할 수 있었고, RA와 luteolin 두 화합물을 동시에 처리할 경우 염증관련 질환 치료에 유용하게 활용될 수 있을 것으로 판단된다.
