Possible antiinflammatory effects of dehydroevodiamine (1) and evodiamine (2) were examined by assessing their effects on NO production in the murine macrophage-like cell line RAW 264.7. The results indicated that both 1 and 2 inhibited the IFN-gamma/LPS-stimulated NO production in a concentration-dependent manner. However, 1 appeared to inhibit NO production by interfering not only with the priming signal initiated by IFN-gamma but also with iNOS protein synthesis, while 2 affected the former only.
通过评估去氢吴茱萸碱(1)和吴茱萸碱(2)对小鼠巨噬细胞样细胞系RAW 264.7中一氧化氮(NO)生成的影响,研究了它们可能的抗炎作用。结果表明,1和2均以浓度依赖性方式抑制IFN-γ/LPS刺激的NO生成。然而,1似乎不仅通过干扰IFN-γ引发的启动信号,还通过干扰诱导型一氧化氮合酶(iNOS)蛋白合成来抑制NO生成,而2仅影响前者。
