  • Acetaminophen (paracetamol) 是选择性环氧合酶-2 (COX-2) 的抑制剂,IC50 值为 25.8 μM。它是广泛使用的解热和止痛药。
  • 本品为解热镇痛药,通过抑制环氧化酶,选择性抑制下丘脑体温调节中枢前列腺素的合成,导致外周血管扩张、出汗而达到解热的作用,其解热作用强度与阿司匹林相似;通过抑制前列腺素等的合成和释放,提高痛阈而起到镇痛作用,属于外周性镇痛药,作用较阿司匹林弱,仅对轻、中度疼痛有效。本品无明显抗炎作用。

COX-2:25.8 μM (IC50)

COX-1:113.7 μM (IC50)

Human Endogenous Metabolite

体外研究 在体外,对乙酰氨基酚引起对COX-2抑制的4.4倍选择性(COX-1的IC50为113.7μM; COX-2的IC50为25.8μM)。口服给药后,最大离体抑制为56%(COX-1)和83%(COX-2)。在给药后至少5小时,对乙酰氨基酚血浆浓度保持在COX-2的体外IC 50之上。离体IC 50值(COX-1:105.2μM; COX-2:26.3μM)的对乙酰氨基酚与其体外IC 50值相比是有利的。与先前的概念相反,对乙酰氨基酚抑制COX-2超过80%,即与非甾体抗炎药(NSAID)和选择性COX-2抑制剂相当的程度。然而,没有达到> 95%COX-1阻断与抑制血小板功能有关[1]。 MTT测定显示,50mM剂量的对乙酰氨基酚(APAP)显着(p <0.001)使细胞活力降低至61.5±6.65%。有趣的是,与对乙酰氨基酚处理的细胞相比,在对乙酰氨基酚/ HV110共处理细胞中观察到细胞存活率显着(p <0.01)增加至79.7±2.47%[2]。
体内研究 对小鼠施用对乙酰氨基酚(250 mg/kg,口服)导致肝脏损伤和细胞坏死显着(p <0.001),血清肝酶丙氨酸氨基转移酶(ALT),氨基转移酶(AST),碱性磷酸酶(ALP)升高证明和γ-谷氨酰转移酶(γGT)与正常组比较。相反,不同剂量柠檬醛(125,250和500 mg/kg)预处理的效果显示ALT血清活性显着(p <0.05)降低(分别为91.79%,93.07%和95.61%), AST(分别为93.40%,91.89%和96.52%),ALP(分别为39.29%,37.07%和59.80%)和γGT(分别为92.83%,91.59%和93.0%),与对乙酰氨基酚组相比。 SLM预处理对ALT活性(95.90%),AST(95.03%),ALP(70.52%)和γGT(92.69%)的影响相似[3]。
细胞实验 人肝癌细胞系HepG2在补充有10%胎牛血清(FBS),100U / mL青霉素和100μg/ mL链霉素和2mM L-谷氨酰胺的低葡萄糖DMEM中培养。将细胞保持在37cm的75cm 2烧瓶中,在含有5%CO 2的潮湿气氛中,并且每5天以80%汇合度分开。将细胞接种在24孔板(2×10 5个细胞)中,并在37℃下孵育过夜,然后用含有高葡萄糖浓度的完全DMEM预处理细胞,以下调自噬。 6小时后,用从发酵乳杆菌BGHV110菌株(HV110)获得的不同浓度的后生物处理细胞,以选择合适的剂量用于进一步的实验。将生物素溶解在完全DMEM培养基中并以特定的最终浓度添加到细胞中。在所有其他实验中,接种细胞用50mM对乙酰氨基酚单独处理或用50mM对乙酰氨基酚和选定剂量的冻干HV110共处理。为了分析自噬通量,在处理的同时,将细胞暴露于浓度为25μM的溶酶体药物氯喹,以抑制自噬体 - 溶酶体融合[2]。
动物实验 小鼠[3]使用雄性Swiss小鼠(30-40g)。将实验动物分成六组,每组五只动物。首先,每组在7天内口服接受以下治疗:第I组:小鼠未接受任何治疗(正常)。第II组:小鼠接受柠檬醛载体(0.1%吐温80溶液)。组III-V:小鼠分别以125,250和500mg / kg的剂量用柠檬醛预处理。第VI组:用保肝标准药物水飞蓟素(SLM)(200mg / kg)预处理小鼠。此后,动物禁食8小时,然后在第7天以250mg / kg的剂量在组II-VI中接受口服对乙酰氨基酚。组I口服接受含有0.1%吐温80溶液(对乙酰氨基酚载体)的盐水。将储备溶液用作50mg / mL的第一浓度,然后在0.1%吐温80溶液中稀释以制备25和12.5mg / mL的溶液。给予对乙酰氨基酚12小时后,收集血清样品和肝组织,然后进行生物化学和组织学分析。

对氨基酚乙酰化而得。方法1:将对氨基酚加入稀乙酸中,再加入冰醋酸,升温至150℃反应7h,加入乙酐,再反应2h,检查终点,合格后冷却至25℃以下,甩滤,水洗至无乙酸味,甩干,得粗品。方法2:将对氨基酚、冰醋酸及含酸50%以上的酸母液一起蒸馏,蒸出稀酸的速度为每小时馏出总量的十分之一,待内温升至130℃以上,取样检查对氨基酚残留量低于2.5%,加入稀酸(含量50%以上),冷却结晶。甩滤,先用少量稀酸洗涤,再用大量水洗至滤液接近无色,得粗品。方法1的收率为90%,方法2的收率为90-95%。精制方法:将水加热至近沸时投入粗品。升温至全溶,加入用水浸泡过的活性炭,用稀乙酸调节至pH=4.2-4.6,沸腾10min。压滤,滤液加少量重亚硫酸钠。冷却至20℃以下,析出结晶。甩滤,水洗,干燥得原料药扑热息痛成品。其他的生产方法还有:(1)在冰醋酸中用锌还原对硝基苯酚,同时乙酰化得到对乙酰氨基酚;(2)将对羟基苯乙酮生成的腙,置于硫酸酸性溶液中,加入亚硝酸钠,转位生成对乙酰氨基酚。
