代谢
氯乙烯主要并在肝脏中快速代谢,这种代谢是可饱和的。氯乙烯代谢的第一步是氧化,这一过程主要是由人类细胞色素P450(CYP)2E1介导,形成高度反应性的氯乙烯环氧化合物,该物质可以自发重排为氯乙醛。氯乙烯环氧化合物和氯乙醛与谷胱甘肽(GSH)结合,最终形成主要的尿液代谢物N-乙酰-S-(2-羟基乙基)半胱氨酸和硫代二乙酸。氯乙烯环氧化合物和氯乙醛也可以通过微粒体环氧化合物水解酶(mEH)解毒为乙二醛,以及通过乙醛脱氢酶2(ALDH2)转化为尿液代谢物氯乙酸。
Vinyl chloride is primarily and rapidly metabolized in the liver, and this metabolism is saturable. ...The first step in the metabolism of vinyl chloride is oxidation, which is predominantly mediated by human cytochrome P450 (CYP) 2E1, to form the highly reactive chloroethylene oxide, which can spontaneously rearrange to chloroacetaldehyde. ... Conjugation of chloroethylene oxide and chloroacetaldehyde with glutathione (GSH) eventually leads to the major urinary metabolites N-acetyl-S-(2-hydroxyethyl)cysteine and thiodiglycolic acid. Chloroethylene oxide and chloroacetaldehyde can also be detoxified to glycolaldehyde by microsomal epoxide hydrolase (mEH) and to the urinary metabolite chloroacetic acid by aldehyde dehydrogenase 2 (ALDH2), respectively.

  • 毒性总结
氯乙烯是一种无色气体或液体(在77华氏度以下)。它被用于塑料工业中制造聚氯乙烯,并在有机合成中使用。它曾被用作制冷剂和喷罐推进剂。在人类研究中,氯乙烯会导致肝血管肉瘤和肝细胞癌。过去职业暴露于几百ppm的氯乙烯,从一个月到三年不等,与“氯乙烯病”的发展有关。氯乙烯病的特点是acroosteolysis(一种以骨骼(主要是手指)溶骨性病变为特征的病症),手指的结缔组织硬皮病伴有皮肤增厚,以及Raynaud样症状,可逆的小动脉收缩导致手指麻木、苍白和发绀。将acroosteolysis归因于氯乙烯暴露几乎完全基于病例报告,并估计影响<3%的从事氯乙烯聚合的工人。在患有慢性职业暴露的患者中,神经学障碍包括感觉运动多发性神经病、三叉神经感觉神经病、轻微的锥体体征和脑干及锥体外系运动障碍。精神障碍包括神经衰弱或抑郁综合征。失眠和性功能丧失是常见的问题。在很大比例的患者中发现了病理性脑电图改变。在36名长期工业暴露的氯乙烯致肝损伤的工人中发现了慢性肝卟啉代谢障碍。病理性卟啉尿,尤其是次级粪卟啉尿转为亚临床慢性肝卟啉病,是识别氯乙烯肝损伤的持续病理生物化学参数。在氯乙烯病患者的报告中,主要的免疫异常包括高免疫球蛋白血症和IgG的多克隆增加、冷球蛋白血症、冷纤维蛋白原血症和体内补体的激活。氯乙烯是一种职业致癌物,能在人类细胞中引起微核。当与57名男性工人的培养外周淋巴细胞进行比较时,对照组的染色体异常显著增加。姐妹染色单体交换是表明生物学反应的最敏感终点。在动物研究中,大鼠、豚鼠和小鼠暴露于100,000至400,000 ppm的氯乙烯浓度下30分钟被证明是致命的。大鼠和小鼠的中毒症状包括肌肉不协调和抽搐、中枢神经系统抑制和呼吸衰竭。在急性暴露于高浓度(375-700 mg/L)氯乙烯气体的家兔、豚鼠和大鼠中,观察到强烈的唾液分泌和流泪。当液体氯乙烯接触到皮肤或眼睛时,它可能会冻伤组织,并在蒸发时产生化学烧伤,从而损害下层组织。暴露于65,000 mg/cu m氯乙烯90分钟的豚鼠中报告了深度中枢神经系统抑制。在这个剂量水平,5分钟暴露后观察到共济失调。在大鼠和小鼠中观察到了氯乙烯的麻醉作用。研究者报告了在260,000 mg/cu m氯乙烯暴露30分钟的大鼠和小鼠中深度中枢神经系统抑制。中枢神经系统抑制效应之前,5分钟后活动增加,10分钟后四肢抽搐,15分钟后共济失调和颤抖。暴露于130,000 mg/cu m氯乙烯60分钟的大鼠表现出共济失调,之前有过度活跃但没有中枢神经系统抑制效应。40只家兔每周5天,每天4小时,共12个月暴露于含有(10,000 ppm)氯乙烯的空气中。在9到15个月的暴露期间,观察到12个皮肤角化病和6个肺腺癌。在15个月的观察期内,20只对照组没有出现类似的肿瘤。大鼠从13周龄(每组120只)或1天龄(43只和46只)开始,每周5天,每天4小时暴露于10,000 ppm氯乙烯的空气中,持续5周,观察了135周。在老年大鼠中报告了1个肝细胞瘤,在新生大鼠中报告了10个血管肉瘤和15个肝细胞瘤。249只对照组中没有报告肝肿瘤。在小鼠、大鼠和家兔的妊娠第6至18天,每天7小时给予氯乙烯。尽管观察到母体毒性,但结论是单独氯乙烯在测试的浓度下没有引起显著的胚胎或胎儿毒性,并且在任何一种物种中都不是致畸的。氯乙烯在雄性果蝇Drosophila melangaster中显著增加了隐性致死突变的发生率。在酵母(S. pombe和S. cerevisiae)存在代谢激活的情况下,报告了氯乙烯的致突变活性。当小鼠口服700 mg/kg氯乙烯时,氯乙烯在“宿主介导”试验中对S. pombe具有致突变性。使用Salmonella测试菌株,在空气(200,000 ppm)中20%(v/v)的氯乙烯在无代谢激活的情况下报告了直接致突变性。致突变反应通过代谢激活增加。然而,20%氯乙烯(空气中的v/v)在使用S. typhimurium菌株TA1536、TA1537和TA1538的系统中被认为是无效的
IDENTIFICATION AND USE: Vinyl chloride is a colorless gas or liquid (below 77 degrees F). It is used in the plastics industry to manufacture polyvinyl chloride, and in organic syntheses. It has been used as refrigerant and spray can propellant. HUMAN STUDIES: Vinyl chloride causes angiosarcoma of the liver, and hepatocellular carcinoma. Past occupational exposure to several hundred ppm of vinyl chloride for periods ranging from one month to 3 years has been associated with development of "vinyl chloride disease". Vinyl chloride disease is characterized by acroosteolysis, a condition characterized by lytic lesions of bones (primarily of fingers), scleroderma of the connective tissue in the fingers with dermal thickening, and a Raynaud-like condition with reversible arteriole constriction causing numbness, pallor and cyanosis of the fingers. The attribution of acroosteolysis to vinyl chloride exposure is based almost entirely on case reports and has been estimated to affect <3% of workers involved in the polymerization of vinyl chloride. In patients with chronic occupational exposure, neurological disturbances include sensory-motor polyneuropathy, trigeminal sensory neuropathy, slight pyramidal signs and cerebellar and extrapyramidal motor disorders. Psychiatric disturbances included neurasthenic or depressive syndromes. Sleeplessness and loss of sexual functions were frequently encountered. Pathological EEG alterations were found in a high proportion of patients. A chronic hepatic disorder of porphyrin metabolism was found in 36 workers with vinyl chloride-induced hepatic injury following long-time industrial exposure. Pathologic porphyrinuria, especially secondary coproporphyrinuria with transition to subclinical chronic hepatic porphyria, is a consistent pathobiochemical parameter for the recognition of vinyl chloride hepatic lesions. The major immunological abnormalities reported in vinyl chloride disease patients include hyperimmunoglobulinemia with a polyclonal increase in IgG, cryoglobulinemia, cryofibrinogenemia, and in vivo activation of complement. Vinyl chloride is an occupational carcinogen which caused micronuclei in human cells. There was significant increase in chromosomal abnormalities in cultured peripheral lymphocytes from 57 male workers when compared with controls. Sister chromatid exchange was the more sensitive endpoint for indicating a biological response. ANIMAL STUDIES: Brief (30 minutes) exposures to concentrations of vinyl chloride ranging from 100,000 to 400,000 ppm have been shown to be fatal in rats, guinea pigs and mice. Symptoms of intoxication in rats and mice include muscular incoordination and twitching, CNS depression and respiratory failure. Intense salivation and lacrimation have been noted in rats, guinea pigs and rabbits exposed acutely to high concentrations (375-700 mg/L) of vinyl chloride gas. When placed on skin or in eyes, liquid vinyl chloride may freeze tissue and produce a chemical burn as it evaporates, causing damage to the underlying tissue. Profound CNS depression was reported in guinea-pigs exposed to vinyl chloride at 65,000 mg/cu m for 90 min. Ataxia was observed at this dose level after 5 min of exposure. The anesthetic action of vinyl chloride was also observed in dogs and mice. Investigators reported deep CNS depression in rats and mice exposed to 260,000 mg/cu m for 30 min. The CNS depressant effect was preceded by increased motor activity after 5 min of exposure, twitching of extremities (after 10 min), ataxia (after 15 min) and tremor (after 15 min). Rats exposed to 130,000 mg/cu m for 60 min showed ataxia preceded by hyperactivity but no /CNS depressant/ effect. Forty rabbits were exposed for 4 hours/day on 5 days/week for 12 months to air containing (10,000 ppm) vinyl chloride. Between 9 and 15 months exposure, 12 skin acanthomas and 6 lung adenocarcinomas were seen. No similar tumors occurred in 20 controls after 15 months observation. Rats were exposed to 10,000 ppm vinyl chloride in air for 4 hours/day on 5 days/week for 5 weeks, starting at the age of 13 weeks (120 rats per group) or 1 day (43 and 46 rats). Animals were observed for 135 weeks. One hepatoma was reported in the older rats in newborn rats, 10 angiosarcomas and 15 hepatomas were found. No liver tumors were reported in 249 controls. Vinyl chloride was administered for 7 hr/day on days 6-18 of gestation in mice, rats, and rabbits. It was concluded that although maternal toxicity observed, vinyl chloride alone did not cause significant embryonal or fetal toxicity and was not teratogenic in any of the species at concentrations tested. Vinyl chloride produced a significant increase in the frequency of recessive lethal mutations in male Drosophila melangaster. Mutagenic activity of vinyl chloride was reported in yeast (S. pombe and S. cerevisiae) in the presence of metabolic activation. Vinyl chloride was mutagenic to S. pombe in the "host mediated" assay when mice were treated with an oral dose of 700 mg/kg of vinyl chloride. Using Salmonella tester strains, direct mutagenicity of vinyl chloride was reported at 20% (v/v) in air (200,000 ppm) in the absence of metabolic activation. Mutagenic response was increased by metabolic activation. However, 20% vinyl chloride (v/v in air) was inactive in systems employing S. typhimurium strains TA1536, TA1537 and TA1538. ECOTOXICITY STUDIES: In Daphnia magna exposure, results indicated impacts of vinyl chloride on the regulation of genes related to glutathione-S-transferase (GST), juvenile hormone esterase (JHE), and the vitelline outer layer membrane protein (VMO1).

  • 毒性总结
氯乙烯中毒表现出许多自身免疫性疾病的特征。这被认为是氯乙烯的中间代谢物与免疫球蛋白结合,改变蛋白质并引发免疫反应的结果。氯乙烯的代谢物,尤其是氯乙基氧化物,具有诱变性,并通过与DNA共价结合发挥作用。这会产生环状亚乙基加合物,在转录和DNA交联期间导致碱基对转换。代谢物还可能引起氧化应激,影响肿瘤抑制基因,因为氯乙烯已知会在p53和Ki-ras基因中产生特异性突变。还认为氯乙烯代谢物通过共价结合肝蛋白,在肝脏中产生毒性作用,导致细胞毒性。(L3, A65)
Vinyl chloride poisoning exhibits many of the characteristics of autoimmune diseases. This is believed to be the result of a reactive vinyl chloride intermediate metabolite binding to an immunoglobulin, altering the protein and initiating an immune response. The metabolites of vinyl chloride, especially choloroethylene oxide, are mutagenic and act by covalently binding to DNA. This produces cyclic etheno-adducts, which cause base-pair transitions during transcription and DNA crosslinks. Metabolites also may cause oxidative stress and affecting tumor supressor genes, as vinyl chloride has been known to produce specific mutations in the p53 and Ki-ras genes. Vinyl chloride metabolites are also believed to exert toxic effects in the liver by covalently binding to liver proteins, resulting in cellular toxicity. (L3, A65)

    摘要:
    本文披露了一种将烯烃转化为环氧化物的催化方法。该方法通常包括在特定银催化剂的存在下,将烯烃与氧气反应,以在适宜条件下产生环氧化物的产量。特定的银催化剂是具有多个表面平面的银纳米晶体,其中有相当一部分由(100)的米勒指数定义。该反应通过向适当的反应器充入银催化剂,然后在适宜条件下向反应器中投入反应物来进行。该反应可以是批量进行,也可以作为一种连续过程进行,其中回收任何未反应的烯烃。特定的银催化剂对环氧化物产品具有意外的高选择性。因此,这种通用方法(及其各种实施形式)将导致迄今为止无法实现的极高环氧化物产量。

  • Photo-degradation of yperite over V, Fe and Mn-doped titania–silica photocatalysts

    The photocatalytic decomposition of yperite (bis(2-chloroethyl)sulfide), a chemical warfare agent, was achieved by using titania–silica catalysts doped with several transition metal ions. The preparation of these catalysts was achieved by impregnation of a titania–silica mixed oxide previously synthesized using a sol-gel route with salts of the doping elements (vanadium, iron, manganese). The above catalysts were characterized using several spectroscopic techniques: FTIR, Raman, DR-UV-Vis, and XPS. The band gap energy was measured for each photocatalytic system. The reaction was carried out in two different types of reactors, i.e. naturally aerated and a closed quartz tube aerated under a constant flow, and using two types of irradiation, UV-Vis and Vis. The investigated systems proved to be extremely active, leading to an almost complete degradation of yperite in 2 h of irradiation. An excellent correlation between the photocatalytic performances and the band gap has been found. Based on the characterization data and on the temporal evolution of the reaction products, a reaction mechanism has been suggested. This mechanism considers two distinct pathways for the decomposition of yperite, namely the C–S bond cleavage and the S oxidation.
    采用掺杂多种过渡金属离子的二氧化钛-二氧化硅催化剂,实现了化学战剂伊皮尔(双(2-氯乙基)硫)的光催化分解。这些催化剂是通过将预先采用溶胶-凝胶法制备的二氧化钛-二氧化硅混合氧化物,与掺杂元素(钒、铁、锰)的盐进行浸渍制备而成。上述催化剂采用多种光谱技术进行了表征:傅里叶变换红外光谱(FTIR)、拉曼光谱、漫反射紫外-可见光谱(DR-UV-Vis)和X射线光电子能谱(XPS)。对每种光催化体系进行了禁带宽度测量。反应在两种不同类型的反应器中进行,即自然通风和在恒定流速下通气的封闭石英管,并采用两种类型的辐照,即紫外-可见光(UV-Vis)和可见光(Vis)。研究表明,这些体系活性极高,在2小时的辐照下,几乎能完全降解伊皮尔。光催化性能与禁带宽度之间存在极佳的相关性。根据表征数据和反应产物的时间演变,提出了一个反应机制。该机制考虑了两种不同的伊皮尔分解途径,即C-S键断裂和S氧化。

    An alkoxide-catalyzed directed diboration of alkenyl alcohols is described. This reaction occurs in a stereoselective fashion and is demonstrated with cyclic and acyclic homoallylic and bishomoallylic alcohol substrates. After oxidation, the reaction generates 1,2-diols such that the process represents a method for the stereoselective directed dihydroxylation of alkenes.
