[体外研究]

水杨酸是COX-2活性的有效抑制剂,其浓度远低于抑制NF-κB(20mg/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。急性水杨酸(30分钟)也引起在0,1或10μM外源花生四烯酸存在下测量的COX-2活性的浓度依赖性抑制。相反,当外源花生四烯酸增加至30μM时,水杨酸是COX-2活性的非常弱的抑制剂,IC50>100μg/ mL。当与IL-1β一起加入24小时时,水杨酸引起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)。在不存在添加的花生四烯酸的情况下或在1或10μM外源底物存在下,水杨酸引起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小鼠中水杨酸处理后存在降低血浆甘油三酯水平的趋势(P = 0.059)。水杨酸显着降低C57Bl/6DIO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,水杨酸也降低了11β-HSD1酶的活性[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，然后加入10单位酶（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]

为了评估水杨酸对诱导后COX-2活性的直接影响，首先用IL-1β处理A549细胞24小时，并用含有不同浓度水杨酸的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（C57B1 / 6DIO）后或达到目标体重（HSD1KO-DIO）后给予水杨酸（120mg / kg /天）通过渗透性微型泵在肩胛骨之间皮下植入n = 8组的4周。

将苯酚与50%氢氧化钠按1：1.02（mol)配比加入反应器中进行反应脱水，控制游离碱≤1%，减压脱水后，再加苯酚作溶剂共沸脱水。然后将苯酚钠在苯酚中通入干燥的二氧化碳气体，进行羧化反应3h后，第二次通入二氧化碳2h，再减压回收苯酚，即羧化完毕。再向上述水杨酸钠溶液中，加入水溶解成50%的溶液，在搅拌下加入7%-8%的硫酸酸化至pH值1-2，然后冷却过滤，真空干燥，即得水杨酸粗品，再将粗品在减压下升华，可得含量为99%的成品水杨酸，收率50%-70%。（2）中压法仍以苯酚为原料，先制成酚钠，在中压下用二氧化碳进行羧基化，生成碳酸苯酚酯，然后加压进行分子重排，生成水杨酸钠，再经酸化后处理制得水杨酸。将苯酚用50%液碱中和，真空干燥，然后将釜温冷却至100℃,慢慢通入干燥的二氧化碳，当釜内压力达0.7-0.8Mpa时，停止通二氧化碳，此时生成碳酸苯酚酯钠，然后在130-140℃下发生分子内重排异构化，变为水杨羧钠，再用硫酸酸化，得水杨酸粗品。将粗品在减压下升华，即得水杨酸精品，含量99%，收率达98%以上。消耗定额（kg/t):苯酚（98%）704，烧碱（95%）417，硫酸（95%）500，二氧化碳（99%）467。（3）制法苯酚与氢氧化钠反应生成酚钠盐，然后再与二氧化碳合成邻羟基苯甲酸钠，经酸化制得水杨酸：粗品用水溶解后经活性炭脱色，再重结晶提纯。（4）将相同物质量的苯酚和50%的氢氧化钠在105～130℃下反应生成酚钠，控制游离碱1%以内。反应结束后，减压脱水，再用苯酚为溶剂共沸脱水。冷却至100℃后，通入干燥的二氧化碳进行3h羧化反应，温度由128℃升至200℃。待温度下降后，回收溶剂苯酚，2～3h后，再通入二氧化碳羧化2h，减压回收苯酚。（羧化的另一种方法是在140～180℃通二氧化碳，控制反应压力为0.7～0.8MPa进行羧化反12h。）羧化反应结束后，加水溶解水杨酸钠，调成50%的溶液，边搅拌边加入7%～8%的硫酸溶液，使ph值达1～2，冷却、过滤、甩干，用水洗涤数次，甩干后，再用蒸馏水加热溶解，加入少
量活性炭，煮沸，趁热过滤，滤液冷却重复用蒸馏水溶解，过滤、甩干数次，即可得纯品水杨酸。所得水杨酸粗品也可用减压升华精制。过程反应式为： 2. 烟草：OR，44；OR，26；FC，9；FC，54；BU，26；FC，40。
