硫化氢 (H2S) 在炎症中的作用仍不清楚,该气体具有促炎和抗炎作用。我们现在已经在体外评估了 GYY4137(一种缓释 H2S 供体)对脂多糖(LPS)诱发的人滑膜细胞(HFLS)和关节软骨细胞(HAC)释放炎症介质的影响。我们还研究了 GYY4137 在小鼠急性关节炎症的完全弗氏佐剂 (CFA) 模型中的作用。 GYY4137 (0.1–0.5 mM) 减少了 LPS 诱导的 HFLS 和 HAC 中亚硝酸盐 (NO2−)、PGE2、TNF-α 和 IL-6 的产生,降低了诱导型一氧化氮合酶 (iNOS) 和环氧合酶-2 (COX-2) 的水平和催化活性,并减少了 LPS 诱导的体外 NF-κB 激活。使用重组人酶,GYY4137 抑制 COX-2、iNOS 和 TNF-α 转换酶 (TACE) 的活性。在 CFA 治疗的小鼠中,CFA 前 1 小时注射 GYY4137(50 mg/kg,腹腔注射)可增加膝关节肿胀,同时具有抗炎作用,滑液髓过氧化物酶 (MPO) 和 N-乙酰基-β-D-氨基葡萄糖苷酶 (NAG) 活性降低以及 TNF-α、IL-1β 降低证明了这一点。 当 CFA 后 6 小时注射 GYY4137 时,IL-6 和 IL-8 浓度很明显。 CFA 后 18 小时给予 GYY4137 也具有抗炎作用。因此,尽管 GYY4137 在体外持续减少人关节细胞促炎介质的产生,但其对体内急性关节炎症的影响取决于给药时间。
The role of hydrogen sulfide (H2S) in inflammation remains unclear with both pro- and anti-inflammatory actions of this gas described. We have now assessed the effect of GYY4137 (a slow-releasing H2S donor) on lipopolysaccharide (LPS)-evoked release of inflammatory mediators from human synoviocytes (HFLS) and articular chondrocytes (HAC) in vitro. We have also examined the effect of GYY4137 in a complete Freund's adjuvant (CFA) model of acute joint inflammation in the mouse. GYY4137 (0.1–0.5 mM) decreased LPS-induced production of nitrite (NO2−), PGE2, TNF-α and IL-6 from HFLS and HAC, reduced the levels and catalytic activity of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) and reduced LPS-induced NF-κB activation in vitro. Using recombinant human enzymes, GYY4137 inhibited the activity of COX-2, iNOS and TNF-α converting enzyme (TACE). In the CFA-treated mouse, GYY4137 (50 mg/kg, i.p.) injected 1 hr prior to CFA increased knee joint swelling while an anti-inflammatory effect, as demonstrated by reduced synovial fluid myeloperoxidase (MPO) and N-acetyl-β-D-glucosaminidase (NAG) activity and decreased TNF-α, IL-1β, IL-6 and IL-8 concentration, was apparent when GYY4137 was injected 6 hrs after CFA. GYY4137 was also anti-inflammatory when given 18 hrs after CFA. Thus, although GYY4137 consistently reduced the generation of pro-inflammatory mediators from human joint cells in vitro, its effect on acute joint inflammation in vivo depended on the timing of administration.
