The synergistic anti-inflammatory effect of the combination of sodium ferulate and oxymatrine and its modulation on inflammation-associated mediators in RAW 264.7 cells.

The combination of Radix Angelicae sinensis (Oliv.) Diels and Radix Sophora flavescens Ait. was extensively used in traditional Chinese medicine to treat inflammatory diseases, such as acne, heart disease, and hepatitis. Sodium ferulate (SF) and oxymatrine (OMT) were effective component of Radix Angelicae sinensis (Oliv.) Diels and Radix Sophora flavescens Ait., respectively.
In this study, we investigated the synergistic anti-inflammatory effect of the combination of SF and OMT, and its modulation on inflammation-associated mediators in RAW 264.7 cells.
In vivo, the anti-inflammatory effects of the combination of SF and OMT were evaluated with the xylene-induced mouse ear edema model and the carrageenan-induced rat paw edema model. In vitro, chemokines and cytokines mRNA expressions in lipopolysaccharide (LPS)-activated RAW 264.7 cells were determined by real-time PCR (RT-PCR) microarray analysis. The levels of interleukin-11 (IL-11), C-reactive protein (CRP) and interferon-γ (INF-γ) in the supernatant of LPS-stimulated RAW 264.7 cells were measured by enzyme-linked immune-sorbent assay (ELISA).
The combination of SF and OMT could significantly inhibit the edema in the xylene-induced mouse ear edema and carrageenan-induced rat paw edema, but no effect was found when each drug was used alone according to above doses. The combination exhibited a better effect in down-regulating mRNA expressions of inflammation-associated mediators in LPS-stimulated RAW 264.7 cells than SF or OMT alone. The ELISA results showed that the combination synergistically inhibited LPS-induced IL-11, CRP and INF-γ production in a dose-dependent manner.
The combination of SF and OMT showed synergistic anti-inflammatory effect, and the activity was probably related to its modulation on inflammation-associated mediators, especially IL-11, CRP and INF-γ.
