体外研究 水杨酸钠是一种有效的COX-2活性抑制剂,其浓度远低于抑制NF-κB(20 mg/mL)活化所需的浓度。当与白细胞介素1β一起加入24小时时,水杨酸钠抑制前列腺素E2释放,IC50值为5μg/ mL,这种作用不依赖于NF-κB活化或COX-2转录或翻译。在0,1或10μM外源花生四烯酸存在下,急性(30分钟)水杨酸钠也引起浓度依赖性的COX-2活性抑制。相反,当外源花生四烯酸增加至30μM时,水杨酸钠是一种非常弱的COX-2活性抑制剂,IC50>100μg/ mL。当与IL-1β一起加入24小时时,水杨酸钠引起PGE 2释放的浓度依赖性抑制,表观IC 50值为约5μg/ mL。在暴露30分钟后测试水杨酸钠直接抑制A549细胞中COX-2活性的能力,然后加入不同浓度的外源花生四烯酸(1,10和30μM)。在没有添加花生四烯酸的情况下或在1或10μM外源底物存在下,水杨酸钠引起COX-2活性的浓度依赖性抑制,表观IC 50值为约5μg/ mL。然而,当使用30μM花生四烯酸进行相同的实验时,水杨酸钠是COX-2活性的无效抑制剂,表观IC50值大于100μg/ mL,并且实现最大抑制小于50%[ 1]。
体内研究 在C57Bl/6 DIO小鼠中,水杨酸盐降低空腹和餐后血浆葡萄糖水平。此外,在C57Bl/6DIO小鼠中水杨酸盐处理后存在降低血浆甘油三酯水平的趋势(P = 0.059)。水杨酸盐显着降低C57Bl/6 DIO小鼠网膜脂肪组织中的11β-HSD1 mRNA,其在肠系膜脂肪中具有相似的趋势(P = 0.057)。在C57Bl/6 DIO小鼠的肠系膜脂肪中,水杨酸盐还降低了11β-HSD1酶活性[2]。
激酶实验 将人纯化的COX-2和辅因子谷胱甘肽(5mM),肾上腺素(5mM)和血红素(1μM)溶解于50mM Tris缓冲液(pH7.5)中。首先将血红素溶于100mM的1M NaOH浓缩原液中,然后在Tris缓冲液中进一步稀释。酶反应在96孔板的各孔中进行,最终反应体积为200μL。向板中加入不同浓度的水杨酸钠,然后加入10单位的酶(180μL)。将板在37°温育30分钟,然后再加入花生四烯酸(10nM至30μM)15分钟。通过将板加热至100℃持续5分钟来终止反应。然后将96孔板以10,000×g离心10分钟,取出适当的样品并加入放射免疫测定[1]。
细胞实验 为了评估水杨酸钠在诱导后对COX-2活性的直接影响,首先用IL-1β处理A549细胞24小时,并用含有不同浓度的水杨酸钠的DMEM替换培养基(10,100和1000μg/ mL)。将细胞在37℃下孵育30分钟。然后加入花生四烯酸(1-30μM)15分钟,取出培养基用于测量PGE2 [1]。
动物实验 小鼠[2]成年雄性C57Bl / 6小鼠在12周龄。饮食诱导的肥胖C57Bl / 6小鼠(C57B1 / 6DIO)在治疗前给予10周的高脂肪饮食(58%脂肪,12%蔗糖)。在到达(C57Bl / 6 Lean)后1周,高脂肪喂养10周后(C57Bl / 6 DIO)或达到目标体重后给予水杨酸钠(120mg / kg /天)或蒸馏水(载体) (HSD1KO-DIO)通过渗透性微型泵在肩胛骨之间皮下植入4周至n = 8组。

1.将水杨酸和碳酸氢钠交叉加入蒸馏水中,温度保持60℃,并保持呈酸性状态,同时加入适量乙二胺四乙酸(EDTA)及保险粉。升温至85℃,反应半小时。将合格的反应液经过滤送入沸腾床,85℃干燥得水杨酸。

2.将水杨酸于50℃下溶解于蒸馏水中,在搅拌下慢慢的用稀氢氧化钠中和至ph值5.4~5.8:

54-21-7 preparation

反应结束后脱色过滤,滤液清亮后,减压浓缩至浆状,冷却,过滤出结晶,干燥后即为成品。
