This study was undertaken to elucidate the mechanism of anti-inflammatory action of gentianine, a constituent of Gentiana Macrophylla. The effects of gentianine on lipopolysacharide (LPS)-induced production of pro-inflammatory cytokines were investigated in male Sprague-Dawley rats. For the first time, we found that oral administration of gentianine (10—100 mg/kg) suppressed the increases in tumor necrosis factor-α (TNF-α) (ED50, 37.7 mg/kg) and interleukin (IL)-6 (ED50, 38.5 mg/kg) in the sera from the rats challenged with bacterial LPS (100 μg/kg; i.p.). However, LPS induced production of other interleukins, such as IL-α, was not significantly altered by gentianine. These results suggest that the potential anti-inflammatory action of gentianine might be at least partly based on the suppressed production of TNF-α and IL-6.
本研究旨在阐明龙胆碱(龙胆的一种成分)的抗炎作用机制。在雄性 Sprague-Dawley 大鼠中研究了龙胆碱对脂多糖 (LPS) 诱导的促炎细胞因子产生的影响。我们首次发现口服龙胆碱(10-100 mg/kg)可抑制肿瘤坏死因子-α(TNF-α)(ED50,37.7 mg/kg)和白细胞介素(IL)-6(用细菌 LPS(100 μg/kg;腹腔注射)攻击的大鼠血清中的 ED50,38.5 mg/kg)。然而,LPS 诱导的其他白细胞介素(例如 IL-α)的产生并没有被龙胆碱显着改变。这些结果表明,龙胆碱的潜在抗炎作用可能至少部分是基于抑制 TNF-α 和 IL-6 的产生。
