代谢
我们最近发现,当给予大鼠吸入性麻醉剂氟烷时,一种58 kDa的内质网蛋白会被氟烷代谢物三氟乙酰氯共价三氟乙酰化。尽管这个58 kDa蛋白与据报道对应于磷脂酰肌醇特异性磷脂酶C-α的cDNA推导的氨基酸序列有99%的同一性,但它并没有磷脂酰肌醇特异性磷脂酶C的活性。因此得出结论,报道的磷脂酰肌醇特异性磷脂酶C-α的cDNA实际上编码了一个未知功能的58 kDa内质网蛋白。其他研究者也得出了相同的结论,并显示这个58 kDa蛋白具有蛋白质二硫键异构酶和蛋白酶活性。我们现在报告,患有氟烷肝炎的患者的血清中有抗体与纯化的三氟乙酰化和天然大鼠肝脏58 kDa蛋白反应。这些结果表明,当患者暴露于氟烷时,会形成一种与大鼠肝脏三氟乙酰化-58 kDa蛋白同源的人类肝脏蛋白。在某些患者中,这种蛋白可能变得具有免疫原性,并导致形成特异性抗体和/或特异性T细胞,这些抗体和T细胞可能与三氟乙酰化和天然58 kDa蛋白反应,并最终至少部分地导致氟烷引起的肝炎。
We recently showed that when rats were administered the inhalation anesthetic halothane, a 58 kDa liver endoplasmic reticulum protein became covalently trifluoroacetylated by the trifluoroacetyl chloride metabolite of halothane. Although the 58 kDa protein showed 99% identity to that of the deduced amino acid sequence of a cDNA reported to correspond to phosphatidylinositol-specific phospholipase C-alpha, it did not have phosphatidylinositol-specific phospholipase C activity. It was concluded that the reported cDNA of phosphatidylinositol-specific phospholipase C-alpha actually encoded for the 58 kDa endoplasmic reticulum protein of unknown function. Other researchers have come to the same conclusion and have shown that the 58 kDa protein has protein disulfide-isomerase and protease activities. We now report that patients with halothane hepatitis have serum antibodies that react with both purified trifluoroacetylated and native rat liver 58 kDa proteins. These results suggest that when patients are exposed to halothane a human liver orthologue of the rat liver trifluoroacetylated-58 kDa protein is formed. In certain patients, this protein may become immunogenic and lead to the formation of specific antibodies and or specific T-cells, which may react with both trifluoroacetylated and native 58 kDa proteins, and ultimately be responsible, at least in part, for the hepatitis caused by halothane.

麻醉剂氟烷通过肝脏细胞色素P450系统生物活化生成反应中间体,三氟乙酰氯,该物质能够酰化肝脏蛋白质。在暴露于氟烷的大鼠肝脏切片中,胞质谷胱甘肽-S-转移酶(GST)被识别为主要蛋白质加合物形成的目标。为了确定GST是否也是体内目标,雄性Hartley大鼠在40%氧气中暴露于1%氟烷4小时。在暴露后10小时,取出肝脏并制备微粒体和胞质组分。过去的研究表明,这些条件导致了氟烷中间体与肝蛋白的最大共价结合。通过乙醇沉淀法分离蛋白质,并使用三氯乙酸洗涤以去除未结合的代谢物。通过凝胶过滤和S-己基-谷胱甘肽亲和色谱纯化胞质GST至电泳纯度。使用共价结合氟化物测定法量化蛋白质加合物。氟烷中间体与胞质和微粒体蛋白质的共价结合分别确定为2.0 +/- 0.4和13.2 +/- 2.3 nmol F/mg蛋白质。通过亚硫酸丁氨酸预处理耗尽肝脏谷胱甘肽,仅导致胞质蛋白质的共价结合增加(3.3 +/- 0.4 nmol F/mg蛋白质)。胞质GST的加合物形成确定为4.7 +/- 1.6 nmol F/mg蛋白质。谷胱甘肽-S-转移酶在吸入氟烷暴露后是肝脏中共价修饰的目标。
The anesthetic halothane is bioactivated by the liver cytochrome P450 system to the reactive intermediate, trifluoroacetyl chloride, which can acylate liver protein. Cytosolic glutathione-S-transferase (GST) was identified as a major target for protein adduct formation in guinea pig liver slices exposed to halothane. To determine if GST is also a target in vivo, male Hartley guinea pigs were exposed to 1% halothane in 40% O2 for 4 hr. At 10 hr post exposure, livers were removed and microsomal and cytosolic fractions prepared. Past studies have shown these conditions resulted in maximal covalent binding of halothane intermediates to hepatic protein. Protein was isolated by ethanol precipitation and washed with trichloroacetic acid to remove unbound metabolites. Cytosolic GST was isolated by gel filtration and S-hexyl-glutathione affinity chromatography to electrophoretic purity. Protein adducts were quantified using a covalently bound fluorine assay. Covalent binding of a halothane intermediate to cytosolic and microsomal protein was determined as 2.0 +/- 0.4 and 13.2 +/- 2.3 nmol F/mg protein, respectively. Liver glutathione depletion by buthionine sulfoximine pretreatment produced an increase in covalent binding only to cytosolic proteins (3.3 +/- 0.4 nmol F/mg protein). Adduct formation to cytosolic GST was determined to be 4.7 +/- 1.6 nmol F/mg protein. Glutathione-S-transferase is a target for covalent modification in the liver following an inhalation exposure to halothane.

在患有各种疾病(包括药物引起的疾病)的患者的血清中发现了针对特定人类细胞色素P450的自身抗体。在替尼酸和对氢化阿米替林引起的肝炎病例中,患者血清中的自身抗体分别针对细胞色素P450 2C9和P450 1A2。在目前的研究中,我们发现56名被诊断为氟烷性肝炎的患者中有25名(45%)具有与从杆状病毒表达系统纯化的人类细胞色素P450 2E1反应的自身抗体。这些自身抗体抑制了细胞色素P450 2E1的活性,并且似乎主要针对构象表位。此外,因为当细胞色素P450 2E1氧化代谢氟烷时会被三氟乙酰化,所以三氟乙酰化形式的细胞色素P450 2E1可能能够绕过通常对细胞色素P450 2E1存在的免疫耐受。类似的机制可能解释了针对其他细胞靶点形成的自身抗体,这些细胞靶点是氟烷的活性三氟乙酰氯代谢物。
Autoantibodies against specific human cytochrome P450s have been found in the sera of patients suffering from a variety of diseases, including those caused by drugs. In the cases of tienilic acid- and dihydralazine-induced hepatitis, patients have serum autoantibodies directed against cytochromes P450 2C9 and P450 1A2, respectively. In the present study, we have found that 25 of 56 (45%) patients diagnosed with halothane hepatitis have autoantibodies that react with human cytochrome P450 2E1 that was purified from a baculovirus expression system. The autoantibodies inhibited the activity of cytochrome P450 2E1 and appeared to be directed against mainly conformational epitopes. In addition, because cytochrome P450 2E1 became trifluoroacetylated when it oxidatively metabolized halothane, it is possible that the covalently altered form of cytochrome P450 2E1 may be able to bypass the immunologic tolerance that normally exists against cytochrome P450 2E1. A similar mechanism may explain the formation of autoantibodies that have been found against other cellular targets of the reactive trifluoroacetyl chloride metabolite of halothane.

卤烷会导致特异质肝炎,部分原因被认为是免疫反应针对一个或多个内质网(ER)腔蛋白,这些蛋白被卤烷的三氟乙酰氯代谢物共价修饰。在这项研究中,我们在大鼠肝脏中确定了一个170 kDa的卤烷蛋白靶点。当使用针对几种内质网驻留蛋白的抗血清对来自卤烷处理大鼠的肝细胞裂解液进行免疫沉淀时,首先检测到了这个170 kDa蛋白。发现这个170 kDa蛋白与其他卤烷的蛋白靶点相关,包括蛋白质二硫键异构酶、蛋白质二硫键异构酶同种型、59 kDa羧酸酯酶和78 kDa葡萄糖调节蛋白。使用针对三氟乙酰化半抗原的抗血清进行免疫印迹表明170 kDa蛋白被三氟乙酰化。根据其亚细胞定位、分子质量、N端氨基酸序列和抗原性,确定三氟乙酰化的170 kDa蛋白为UDP-葡萄糖:糖蛋白葡萄糖基转移酶(UGGT),这是一种内质网腔蛋白,被认为在N-连接糖蛋白的折叠中发挥作用。此外,用卤烷处理大鼠导致肝微粒体UGGT活性降低了44%,至少36%的酶活性变化可能是由于蛋白质水平降低所致。结果表明,UGGT在N-连接糖蛋白折叠中的作用可能受到其他内质网驻留蛋白或卤烷等外源物质的影响。
Halothane causes an idiosyncratic hepatitis that is thought to result, in part, from immune reactions against one or more lumenal endoplasmic reticulum (ER) proteins that have been covalently modified by the trifluoroacetyl chloride metabolite of halothane. In this study, we have identified a 170 kDa protein target of halothane in the liver of rats. The 170 kDa protein was first detected when proteins in lysates of hepatocytes from halothane-treated rats were immunoprecipitated with antisera against several resident ER proteins. This 170 kDa protein was found to be associated with other protein targets of halothane, including protein disulfide isomerase, a protein disulfide isomerase isoform, a 59 kDa carboxylesterase, and 78 kDa glucose-regulated protein. Immunoblotting with antiserum directed against the trifluoroacetylated hapten indicated that the 170 kDa protein was trifluoroacetylated. Based upon its subcellular localization, molecular mass, N-terminal amino acid sequence, and antigenicity, the trifluoroacetylated 170 kDa protein was identified as UDP-glucose:glycoprotein glucosyltransferase (UGGT), a lumenal ER protein that is thought to have a role in the folding of N-linked glycoproteins. Moreover, treatment of rats with halothane caused a 44% decrease in the activity of liver microsomal UGGT, and at least 36% of the change in the activity of the enzyme could be due to a decrease in the level of the protein. The results suggest that the function of UGGT in folding of N-linked glycoproteins may be affected by other resident ER proteins or xenobiotics such as halothane.

  • 毒性总结
三氟乙酰氯(TFA)是一种用于化学合成的气体。TFA也是卤烷的代谢物。人类研究:像卤烷这样的麻醉剂被认为通过将TFA半抗原(卤烷的代谢物)与肝蛋白共价连接来引发肝炎。绝大多数临床诊断为卤烷肝炎的患者血清中有抗体,这些抗体与一个或多个特定肝脏微粒体蛋白发生反应,这些蛋白已经被TFA共价改变。血清抗体对卤烷肝炎患者具有特异性,并且不会在其他类型肝脏病变患者的血清中看到。当使用来自卤烷处理和未处理大鼠的肝脏微粒体的纯化TFA 57-kD蛋白和天然57-kD蛋白作为酶联免疫吸附试验的测试抗原时,卤烷肝炎患者的血清抗体(n = 40)与这两种蛋白的反应程度显著高于对照组患者(n = 32)的血清抗体。在另一项研究中,56名诊断为卤烷肝炎的患者中有25名(45%)具有与人类细胞色素P450 2E1反应的自体抗体。在这种情况下,当细胞色素P450 2E1氧化代谢卤烷时,它会被三氟乙酰化。动物研究:通过吸入40 ppm和90 ppm的TFA暴露导致大鼠死亡和体重下降。在大鼠连续90天暴露于0.1 ppm的TFA蒸气中,肺部和局部淋巴结主要出现淋巴细胞局部反应。从对TFA-蛋白加合物敏感化的兔子的血清中纯化的抗体与TFA-磷脂酰乙醇胺加合物发生交叉反应。这些发现表明,存在于肝细胞表面非层状域中的TFA-磷脂酰乙醇胺加合物可能是抗TFA加合物抗体的识别位点,并可能参与免疫介导的肝毒性。此外,有人提出,在吸入卤烷暴露后,谷胱甘肽-S-转移酶可能是肝脏共价修饰的目标。
IDENTIFICATION AND USE: Trifluororacetyl chloride (TFA) is a gas that is used in chemical synthesis. TFA is also a metabolite of halothane. HUMAN STUDIES: Anesthetics such as halothane are believed to trigger hepatitis by covalently linking a TFA hapten (metabolite of halothane) to hepatic proteins. The vast majority of patients with a clinical diagnosis of halothane hepatitis have serum antibodies, which react with one or more specific liver microsomal proteins that have been covalently altered by the TFA. The serum antibodies are specific to halothane hepatitis patients and are not seen in sera of patients with other types of liver pathology. When the purified TFA 57-kD and native 57-kD proteins from liver microsomes of halothane-treated and untreated rats respectively, were used as test antigens in an enzyme-linked immunosorbent assay, serum antibodies from halothane hepatitis patients (n = 40) reacted with both of these proteins to a significantly greater extent than did serum antibodies from control patients (n = 32). In a separate study 25 of 56 (45%) patients diagnosed with halothane hepatitis had autoantibodies that reacted with human cytochrome P450 2E1. In this case cytochrome P450 2E1 became trifluoroacetylated when it oxidatively metabolized halothane. ANIMAL STUDIES: TFA exposure by inhalation at 40 ppm and 90 ppm produced mortality and body weight loss in rats. Exposure of rats over a 90-day period to vapor of TFA at 0.1 ppm caused a predominantly lymphocytic local response in the lungs and local lymph nodes. Antibodies purified from the sera of rabbits sensitized to a TFA-protein adduct cross-reacted with a TFA-phosphatidylethanolamine adduct. These findings suggest that TFA-phosphatidylethanolamine adducts that reside in nonlamellar domains on the hepatocyte surface could be recognition sites for anti-TFA-adduct antibodies and potentially participate in immune-mediated hepatotoxicity. Furthermore, it was suggested that glutathione-S-transferase could be a target for covalent modification in the liver following an inhalation exposure to halothane.

    Substituent effects in N–H···O hydrogen bonds were estimated by comparing the acidities of two series of model compounds: N-benzoylanthranilic acids (A) and 4-benzoylamidobenzoic acids (B). Intramolecular N–H···O hydrogen bonds were found to be present in the A series of compounds, while B acids were used as control models. The respective pKa values for A and B acids were determined experimentally
