[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。

水杨酸合成路线

水杨酸上下游产品

水杨酸制备

1. 苯酚与氢氧化钠反应生成苯酚钠,蒸馏脱水后,通二氧化碳进行羧基化反应,制得水杨酸钠盐,再用硫酸酸化,而得粗品。粗品经升华精制得成品。原料消耗定额:苯酚(98%)704kg/t、烧碱(95%)417kg/t、硫酸(95%)500kg/t、二氧化碳(99%)467kg/t。该法分为常压法和中压法。 (1)常压法 将苯酚与50%的氢氧化钠溶液配制成苯酚钠,使游离碱在1%以内,减压脱水后,加苯酚作溶剂共沸脱水。然后苯酚钠在溶剂苯酚中通入干燥的二氧化碳羧化,再用硫酸酸化即得成品。

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。
