  • 毒性总结
识别和使用:乙胺(EA)是一种无色气体或水白色液体(在62华氏度以下)。它用于树脂化学;作为橡胶乳液的稳定剂;染料、药物的中介;在炼油中;在有机合成中。乙胺已被确认为在液压破碎中作为交联剂使用。人类暴露和毒性:脂肪胺的气体、蒸气或液体具有高度刺激性,可能导致眼睛或皮肤严重损伤。呼吸道的刺激可能导致流鼻涕、咳嗽和呼吸困难。可能会出现喉痉挛和肺水肿的迹象(呼吸急促、发绀和咳痰)。对于大多数暴露的人来说,症状会在几周或几个月内消失。严重吸入损伤的幸存者,尤其是如果胸部x光和肺功能异常有关,可能会留下慢性肺病。在眼睛与脂肪胺液体接触的情况下,可能会造成永久性损害和视力障碍。乙胺已被报道会导致肾上腺皮质坏死。在三个肾上腺区域中,髓质、球状带和束状带/网状带,最后一个对毒性损伤最敏感,这是乙胺的情况。内分泌腺对毒性损伤的敏感性以下列降序发生:肾上腺、睾丸、甲状腺、卵巢、胰腺、垂体和副甲状腺。动物研究:70%的溶液涂抹在豚鼠皮肤上,导致立即烧伤导致坏死;当与豚鼠接触2小时时,出现严重的皮肤刺激,广泛的坏死和深疤痕。当涂抹在兔子的皮肤上时,产生少量的发红,表明该物质对皮肤只有轻微的刺激性。在大鼠吸入实验中,大鼠暴露于5000-12000毫克/立方米的浓度四小时,乙胺主要作用于眼睛(角膜肿胀和乳白色外观,眼睛肿胀),鼻子(水样分泌物),皮肤(眼睑的蚀刻效应)和肺(呼吸困难)。死亡动物的形态学检查显示大脑急性充血和肺边缘性肺气肿的血点。家兔在50 ppm乙胺中每天7小时,每周5天,连续6周暴露,对肺和眼睛产生刺激。肺病变包括支气管周围炎和肺炎,伴小血管增厚。眼的变化包括多个角膜上皮糜烂和角膜水肿以及瞬膜水肿。一些家兔出现心脏局灶性肌肉萎缩。在14天的喂养实验中,小鼠和大鼠摄入2.5%,诱导巨大线粒体。氧化磷酸化没有改变,巨大线粒体形成是可逆的。乙胺在沙门氏菌测试中呈阴性,在大肠杆菌中产生姐妹染色单体交换增加。
IDENTIFICATION AND USE: Ethylamine (EA) is a colorless gas or water-white liquid (below 62 degrees F). It is used in resin chemistry; as stabilizer for rubber latex; intermediate for dyestuffs, medicinals; in oil refining; in organic syntheses. EA has been identified as being used in hydraulic fracturing as a crosslinker. HUMAN EXPOSURE AND TOXICITY: Gas, vapor or liquid of aliphatic amines is highly irritating and can cause serious injuries to eyes or skin. Irritation of the respiratory tract can result in rhinorrhea, coughing, and dyspnea. Laryngospasm and signs of pulmonary edema (shortness of breath, cyanosis, and expectoration) may occur. For most exposed individuals symptoms will clear over several weeks or months. Survivors of severe inhalation injury, especially if chest x-ray and pulmonary function abnormalities are associated, may suffer residual chronic lung disease. In cases of eye contact with liquid aliphatic amines, permanent damage and impairment of vision can result. Ethylamine has been reported to cause adrenal cortical gland necrosis. Of the three adrenal gland areas, medulla, zona glomerulosa, and zona fasciculata/reticularis, the last is most sensitive to toxic injury, which is the case with ethylamine. Sensitivity of endocrine glands to toxic insult occurs in the following decreasing order: adrenal, testis, thyroid, ovary, pancreas, pituitary, and parathyroid. ANIMAL STUDIES: A 70% solution applied to the skin of guinea pigs resulted in prompt skin burns leading to necrosis; when it was held in contact with guinea pigs for 2 hr, there was severe skin irritation with extensive necrosis and deep scarring. When applied to the skin of a rabbit, a small amount of redness was produced, indicating the material to be only mildly irritating to the skin. After an inhalatory experiment in which rats were exposed for four hours to concentrations of 5000-12000 mg/cu m, ethylamine mainly acted on the eyes (swelling and milky look of the cornea, swollen eyes), nose (watery secretion), skin (etching effect on the eyelid), and the lungs (dyspnea). Morphological examination of the animals which died revealed an acute hyperemia in the brain and blood filled spots with border emphysema in the lung. Rabbits exposed 7hr/day, 5days/week for 6 weeks at 50 ppm ethylamine produced irritation of the lungs and eyes. The lung lesions included peribronchitis and pneumonitis with thickening of small blood vessels. The ocular changes involved multiple epithelial erosions and edema of the cornea along with edema of the nictitating membrane. Focal muscular degeneration of the heart was seen in some rabbits. After 14 days feeding experiments with 2.5% with mice and rats, mega mitochondria are induced. Oxidative phosphorylation is not changed and the mega mitochondria formation is reversible. EA was negative in the Salmonella typhimurium assay, Escherichia coli, and produced an increase in sister-chromatid exchanges in Chinese Hamster V79 cells.

毒理性
  • 毒性总结
尿毒症毒素如乙胺通过有机离子转运体(特别是OAT3)被积极运输到肾脏中。尿毒症毒素水平的增加可以刺激活性氧种类的产生。这似乎是通过尿毒症毒素直接结合或抑制NADPH氧化酶酶(特别是肾脏和心脏中丰富的NOX4)(A7868)来介导的。活性氧种类可以诱导几种不同的DNA甲基转移酶(DNMTs),这些酶参与沉默一种名为KLOTHO的蛋白质。KLOTHO被发现具有在抗衰老、矿物质代谢和维生素D代谢中的重要作用。许多研究表明,在急性或慢性肾脏疾病中,由于局部活性氧种类水平升高,KLOTHO mRNA和蛋白质水平会降低(A7869)。
Uremic toxins such as ethylamine are actively transported into the kidneys via organic ion transporters (especially OAT3). Increased levels of uremic toxins can stimulate the production of reactive oxygen species. This seems to be mediated by the direct binding or inhibition by uremic toxins of the enzyme NADPH oxidase (especially NOX4 which is abundant in the kidneys and heart) (A7868). Reactive oxygen species can induce several different DNA methyltransferases (DNMTs) which are involved in the silencing of a protein known as KLOTHO. KLOTHO has been identified as having important roles in anti-aging, mineral metabolism, and vitamin D metabolism. A number of studies have indicated that KLOTHO mRNA and protein levels are reduced during acute or chronic kidney diseases in response to high local levels of reactive oxygen species (A7869).

Various amines were administered orally in the form of hydrochlorides to study the decomposition mechanisms of these compounds as well as their elimination conditions. The volatile alkyl amine nitrogen was measured daily in the urine. Alkyl amines which were eliminated were isolated as picrolonates and identified by melting point and nitrogen content. Only 1.74% to 1.93% of the administered methylamine was passed in the urine. Up to 32% and 14.9%, respectively, was recovered in the urine following dosing with ethylamine and isobutylamine. Up to 9.5% of administered propylamine was found in the urine and identified as a picrolonate. For dimethylamine and diethylamine, recovery in the urine the following day was 91.5% and 86.2%, respectively. /Amine hydrochlorides/

    一系列新的核苷5'-三磷酸盐类似物2、3、5、6、8-10在糖基和所有三个磷酸盐残基处进行了修饰,已被合成并研究。这些化合物仅具有α和β磷原子之间的酶促不稳定的酐键。涉及的制备化学包括制备膦酸盐30、31和32以及将这些物种与吗啉代33耦合。讨论了形成一些中间体形成27和28的机制。所有目标化合物在人体血清中表现出高稳定性,水解半衰期长达4.5天。一些这些核苷三磷酸盐已被证明是对逆转录病毒逆转录酶和终端脱氧核苷酸转移酶催化的DNA合成的选择性抑制剂。它们抑制了感染细胞培养中包含Moloney鼠白血病病毒逆转录酶的人工病毒的复制,这可能是由于基因组RNA的逆转录步骤被抑制。与三磷酸盐相比,相应的单磷酸盐的抗病毒活性降低了1-2个数量级。这意味着三磷酸盐直接抑制病毒复制,而不是通过先水解为单磷酸盐然后细胞内二磷酸化的两步机制。由于完全独立于宿主细胞的酶促磷酸化途径,所研究的化合物也可能在缺乏激酶的细胞系和细胞间血液介质中抑制逆转录病毒的繁殖。
