The substrate specificity of ammonia monooxygenase in whole cells of the nitrifying bacterium Nitrosomonas europaea have been determined for a number of aliphatic halogenated hydrocarbons. The effect of the halogen substituent and carbon chain length on substrate reactivity was studied by measuring the rates of oxidation of monohalogenated ethanes (fluoroethane, chloroethane, bromoethane, and iodoethane) by whole cells of Nitrosomonas europaea. For monohalogenated ethanes, acetaldehyde was the major organic product and little or none of any of the alternate predicted products (2-halogenated alcohols) were detected.

  • 毒性总结
识别和使用:溴乙烷是一种无色液体,其蒸气比空气重。溴乙烷用作化学合成中的乙基化剂。溴乙烷曾用作牙科和医疗手术的麻醉剂。人体研究:与溴乙烷暴露有关的主要健康问题是神经毒性的潜在风险、呼吸道的刺激、遗传物质的损害、致癌性、血液毒性和肝脏毒性。有限的手术麻醉中的人类经验表明,除了中枢神经系统抑制外,还可能发生肺充血和肝、肾组织的变性。暴露于溴乙烷的症状包括皮肤、眼睛、粘膜和上呼吸道的刺激。其他症状包括中枢神经系统抑制、肺刺激、急性充血和水肿、肝损伤和肾损伤。它可引起恶心、头晕、头痛和神经系统紊乱。可能出现中枢神经系统抑制、心脏心律失常和心脏骤停。可能会出现失去平衡、言语不清、昏迷和死亡。摄入可能导致消化道的灼伤、呕吐和中度胃肠不适。可能出现皮疹。在反复暴露后,它可能影响运动控制。已报告心脏损伤。溴乙烷中毒的过程分为三个阶段。第一阶段持续2-4天,涉及呼吸中有大蒜味、嗜睡、疲劳、小腿的剧痛和感觉异常以及蹒跚步态。在持续2-5天的第二阶段,第一阶段的症状变得更加严重。第三阶段以腿部痉挛性感觉异常、周围神经系统障碍和小腿萎缩为特征。在高溴乙烷暴露下也可能发生中枢神经系统障碍。大多数患者的康复预后良好。动物研究:小鼠和大鼠暴露于溴乙烷的立即效应包括呼吸增加、过度活跃、不协调、呼吸困难 和昏迷。溴乙烷对兔子的皮肤和眼睛有明显刺激性,并报告可通过皮肤吸收。将大鼠和兔子暴露于538 ppm溴乙烷,每天4小时,持续6个月,结果显示肝功能紊乱,表现为肝糖原和脂肪水平降低以及戊巴比妥睡眠时间延长。还报告了肝细胞颗粒营养不良和细胞质RNA水平降低。另一项研究报告称,大鼠暴露于538 ppm溴乙烷,也是通过吸入,导致垂体腺增生和肥大、皮质肥大和肾上腺脂质含量增加。在1600 ppm(7.14 g/cu m)的溴乙烷中观察到严重的睾丸萎缩,但在较低浓度下未观察到。在雌性小鼠(而不是大鼠)中,卵巢中的黄体大小和数量在1600 ppm(7/10动物)和800 ppm(3.57 g/cu m, 3/9动物)时减少。溴乙烷对细菌具有诱变性,但在单一研究中对果蝇没有诱变性。在另一项单一研究中,溴乙烷增加了培养的哺乳动物细胞姐妹染色单体交换的发生率,但未增加染色体畸变的发生率。在一项为期两年的吸入致癌性生物分析中,观察到与剂量相关的雌性小鼠子宫肿瘤增加。在暴露于最高剂量的雌性大鼠中,发现了神经胶质瘤发生率的轻微增加。
IDENTIFICATION AND USE: Ethyl bromide is a colorless liquid with a vapor heavier than air. Ethyl bromide is used as an ethylating agent in chemical synthesis. Ethyl bromide was formerly used as a narcotic agent for dental and medical surgery. HUMAN STUDIES: The main health concerns relating to the exposure of ethyl bromide are the potential for neurotoxicity, irritation of the respiratory tract, damage to genetic material, carcinogenicity, hematotoxicity and hepatotoxicity. Limited human experience during surgical anesthesia has indicated that, in addition to CNS depression, there is a possibility of lung congestion and degeneration of the liver and kidney tissues. Symptoms of exposure to ethyl bromide include irritation of the skin, eyes, mucous membranes, and upper respiratory tract. Other symptoms include CNS depression, lung irritation, acute congestion and edema, liver damage, and kidney damage. It can cause nausea, dizziness, headache, and nervous system disturbances. Central nervous system depression, cardiac arrhythmias, and cardiac arrest may occur. Loss of balance, slurred speech, unconsciousness, and death can occur. Ingestion can cause burning of the digestive tract, vomiting, and moderate gastrointestinal upset. Skin rash may occur. It can affect motor control after repeated exposures. Heart damage has been reported. The course of ethyl bromide poisoning was described in three stages. The first stage lasted 2-4 days and involved a garlicky odor on the breath, sleepiness, fatigue, sharp pain and paresthesia of the lower legs, and staggering gate. During the second phase that lasted 2-5 days, the symptoms of the first phase grew more severe. The third phase was characterized by spastic paresthesia of the legs, disturbance of the peripheral nervous system, and atrophy of the lower leg. CNS disturbances can also occur at high ethyl bromide exposures. Prognosis for recovery is good for most patients. ANIMAL STUDIES: Immediate effects of ethyl bromide exposure in mice and rats included increased respiration, hyperactivity, incoordination, dyspnea, and coma. The liquid is apparently irritating to skin and eyes of rabbits and is reported to be absorbed through the skin. Exposure of rats and rabbits by inhalation at 538 ppm ethyl bromide for 4 hr/day for 6 months resulted in disruption of hepatic function as shown by a decrease in hepatic glycogen and fat levels as well as prolonged hexobarbital sleep. Hepatic cell granular dystrophy and decreased cytoplasmic RNA levels were also reported. Another study reported that exposure of rats, also at 538 ppm of ethyl bromide by inhalation resulted in hyperplasia and hypertrophy of the pituitary gland, hypertrophy of the cortex, and increased lipid content of the adrenal gland. Severe testicular atrophy was observed in rats, but not in mice, at 1600 ppm (7.14 g/cu m) ethyl bromide but not at lower concentrations. ln female mice, but not in rats, the size and number of corpora lutea in the ovary were decreased at 1600 ppm (7/10 animals) and at 800 ppm (3.57 g/cu m, 3/9 animals). Ethyl bromide was mutagenic to bacteria, but not to Drosophila melanogaster in a single study. In another single study, ethyl bromide increased the incidence of sister chromatid exchanges, but not of chromosomal aberrations in cultured mammalian cells. In a two year carcinogenicity bioassay by inhalation, a dose related increase in uterine tumors was observed in female mice. A small increase in the incidence of gliomas was found in female rats exposed to the highest dose used.

  • 毒性总结
有机溴化物化合物,尤其是烷基溴化物,是强烈的烷基化剂。因此,它们可以随机地修改蛋白质和脂质的表面,导致酶、转运蛋白或膜功能的破坏。最可能的蛋白质靶标之一是TRPA1离子通道,它在眼睛、鼻子、嘴巴和肺部的三叉神经(感觉神经)中表达。烷基溴化物对DNA的烷基化也可能导致突变。
Organobromide compounds, especially alkylbromides are strong alkylating agents. Consequently they can randomly modify the surfaces of proteins and lipids, leading to the disruption of enzyme, transporter or membrane functions. One of the most probable protein targets is the TRPA1 ion channel that is expressed in sensory nerves (trigeminal nerve) of the eyes, nose, mouth and lungs. Alkylation of DNA by alkylbromides may also lead to mutations.

制备方法与用途

溴乙烷简介

溴乙烷具有一卤代烷的通性,可水解生成乙醇、与氰化钠作用生成丙腈、与氨、醇、硫化氢作用分别生成胺、醚、硫醇,在无水乙醚中与金属镁作用生成格氏试剂。因此溴乙烷可用于合成多种有机物。

此外,溴乙烷有毒!在光线或火焰下易分解产生溴化氢和碳酰溴,后者有似光气样的剧毒作用。它也用作有机合成的原料及熏蒸剂。

性质

溴乙烷亦称“乙基溴”。分子式为C2H5Br,无色可燃液体,具有特殊甜味,分子量108.98,比重1.4604(20/4℃),沸点38.4℃。能与乙醇、乙醚、氯仿及有机溶剂混溶,难溶于水,水中溶解度为0.91g%(20℃),易挥发且易燃。

健康危害

溴乙烷具有麻醉作用,对人的麻醉浓度为1.34g/m³-4.46g/m³。它能引起肺部刺激和肝、肾、心损害。急性中毒症状包括头痛、眩晕、面部发红、瞳孔散大、脉搏加速等;严重时四肢震颤、呼吸困难、发绀、虚脱,甚至可能导致呼吸麻痹。

长期接触溴乙烷会引发头痛、眩晕、嗜睡、下肢无力和步态蹒跚等症状。脱离接触后,这些症状可逐渐消失。对于牙齿手术,也可用作麻醉药。

化学性质

无色透明易燃、易挥发性液体,具有醚臭和辛辣味,在空气中或遇光明时会变成淡黄色。与乙醇、乙醚、氯仿及其他有机溶剂混溶,微溶于水。

    Novel N-H and N-alkylated derivatives of meridianins have been synthesized as potential antitumor agents by a two-step conversion of N-tosyl-3-acetylindoles or N-alkyl-3-acetylindoles to the corresponding enaminones using DMF-DMA, with or without added pyrrolidine.
