代谢
人体组织中始终存在的小量氰化物以大约17微克/千克·分钟的速度被代谢,主要由肝脏酶类硫氰酸酶催化,该酶催化氰化物与硫烷不可逆反应生成硫氰酸盐,这是一种相对无毒的化合物,通过尿液排出体外……在正常条件下,限制因素是作为硫氰酸酶底物的硫烷的可用性,因此硫以硫代硫酸钠的形式被治疗性地给予,以加速这一反应。氰化物的致死剂量与时间有关,因为身体能够通过硫氰酸酶催化反应与硫烷解毒少量氰化物。缓慢吸收的一定量的氰化物可能不会产生任何生物效应,尽管在非常短的时间内给予相同数量的氰化物可能是致命的。/氢氰酸和氯化氰/
The small quantity of cyanide always present in human tissues is metabolized at the approximate rate of 17 ug/kg x min, primarily by the hepatic enzyme rhodanese, which catalyzes the irreversible reaction of cyanide and a sulfane to produce thiocyanate, a relatively nontoxic compound excreted in the urine. ... The limiting factor under normal conditions is the availability of a sulfane as a substrate for rhodanese, and sulfur is administered therapeutically as sodium thiosulfate to accelerate this reaction. The lethal dose of cyanide is time dependent because of the ability of the body to detoxify small amounts of cyanide via the rhodanese-catalyzed reaction with sulfane. A given amount of cyanide absorbed slowly may cause no biological effects even though the same amount administered over a very short period of time may be lethal. /Hydrogen cyanide and cyanogen chloride/

代谢
氰离子与硫结合形成硫氰酸盐。这种结合反应由酶硫辛酸酶催化,该酶广泛分布于大多数动物组织中,除了血液,尤其是在肝脏中活性较高。硫辛酸酶的机制只能对有限的氰化物量进行解毒,例如在正常代谢过程中形成的那些。另一个硫供体是3-巯基丙酮酸。酶巯基硫酸转移酶定位于细胞质中。

代谢
有机腈通过肝脏中的细胞色素P450酶的作用转化为氰化物离子。氰化物迅速被吸收并在全身分布。氰化物主要通过rhodanese或3-巯基丙酸硫转移酶代谢成硫氰酸盐。氰化物代谢物通过尿液排出。溴主要通过吸入吸收,但也可以通过皮肤接触进入人体。溴盐可以摄入。由于溴的反应性,它迅速形成溴化物并可能沉积在组织中,取代其他卤素。(L626, L96)
Organic nitriles are converted into cyanide ions through the action of cytochrome P450 enzymes in the liver. Cyanide is rapidly absorbed and distributed throughout the body. Cyanide is mainly metabolized into thiocyanate by either rhodanese or 3-mercaptopyruvate sulfur transferase. Cyanide metabolites are excreted in the urine. Bromine is mainly absorbed via inhalation, but may also enter the body through dermal contact. Bromine salts can be ingested. Due to its reactivity, bromine quickly forms bromide and may be deposited in the tissues, displacing other halogens. (L626, L96)

毒理性
  • 毒性总结
有机腈在体内和体外都会分解成氰化物离子。因此,有机腈的主要毒性机制是它们产生有毒的氰化物离子或氢氰酸。氰化物是电子传递链第四复合体(存在于真核细胞线粒体膜中)的细胞色素c氧化酶的抑制剂。它与这种酶中的三价铁原子形成复合物。氰化物与这种细胞色素的结合阻止了电子从细胞色素c氧化酶传递到氧气。结果,电子传递链被破坏,细胞无法再通过有氧呼吸产生ATP能量。主要依赖有氧呼吸的组织,如中枢神经系统和心脏,受到特别影响。氰化物也通过与过氧化氢酶、谷胱甘肽过氧化物酶、变性血红蛋白、羟钴胺素、磷酸酶、酪氨酸酶、抗坏血酸氧化酶、黄嘌呤氧化酶、琥珀酸脱氢酶以及Cu/Zn超氧化物歧化酶结合,产生一些毒性效应。氰化物与变性血红蛋白中的三价铁离子结合形成无活性的氰化变性血红蛋白。溴是一种强氧化剂,能够从粘膜的水分中释放氧气自由基。这些自由基也是强氧化剂,能够产生组织损伤。此外,氢溴酸和溴酸的形成将导致二次刺激。溴离子也被知道会影响中枢神经系统,导致溴中毒。这被认为是溴离子在神经递质和传输系统的反应中替代氯离子的结果,从而影响许多突触过程。(L626,L627,A543,L97)
Organic nitriles decompose into cyanide ions both in vivo and in vitro. Consequently the primary mechanism of toxicity for organic nitriles is their production of toxic cyanide ions or hydrogen cyanide. Cyanide is an inhibitor of cytochrome c oxidase in the fourth complex of the electron transport chain (found in the membrane of the mitochondria of eukaryotic cells). It complexes with the ferric iron atom in this enzyme. The binding of cyanide to this cytochrome prevents transport of electrons from cytochrome c oxidase to oxygen. As a result, the electron transport chain is disrupted and the cell can no longer aerobically produce ATP for energy. Tissues that mainly depend on aerobic respiration, such as the central nervous system and the heart, are particularly affected. Cyanide is also known produce some of its toxic effects by binding to catalase, glutathione peroxidase, methemoglobin, hydroxocobalamin, phosphatase, tyrosinase, ascorbic acid oxidase, xanthine oxidase, succinic dehydrogenase, and Cu/Zn superoxide dismutase. Cyanide binds to the ferric ion of methemoglobin to form inactive cyanmethemoglobin. Bromine is a powerful oxidizing agent and is able to release oxygen free radicals from the water in mucous membranes. These free radicals are also potent oxidizers and produce tissue damage. In additon, the formation of hydrobromic and bromic acids will result in secondary irritation. The bromide ion is also known to affect the central nervous system, causing bromism. This is believed to be a result of bromide ions substituting for chloride ions in the in actions of neurotransmitters and transport systems, thus affecting numerous synaptic processes.

短时间内接触高浓度的氰化物会损害大脑和心脏,甚至可能导致昏迷、癫痫、呼吸暂停、心脏骤停和死亡。长期吸入氰化物会引起呼吸困难、胸痛、呕吐、血变化、头痛和甲状腺肿大。皮肤接触氰化物盐可能会引起刺激和产生溃疡。溴蒸汽会引起刺激和对粘膜的直接损害。元素溴也会烧伤皮肤。溴化物离子是一种中枢神经系统抑制剂,长期暴露会产生神经元效应。这被称为溴中毒,可能导致从中枢反应嗜睡到昏迷、恶病质、昏迷、反射丧失或病理反射、阵挛性癫痫、震颤、共济失调、神经敏感性丧失、麻痹、眼乳头水肿、异常言语、脑水肿、谵妄、攻击性和精神疾病。(L625, L626, L627, L96, L97)
Exposure to high levels of cyanide for a short time harms the brain and heart and can even cause coma, seizures, apnea, cardiac arrest and death. Chronic inhalation of cyanide causes breathing difficulties, chest pain, vomiting, blood changes, headaches, and enlargement of the thyroid gland. Skin contact with cyanide salts can irritate and produce sores. Bromine vapour causes irritation and direct damage to the mucous membranes. Elemental bromine also burns the skin. The bromide ion is a central nervous system depressant and chronic exposure produces neuronal effects. This is called bromism and can result in central reactions reaching from somnolence to coma, cachexia, exicosis, loss of reflexes or pathologic reflexes, clonic seizures, tremor, ataxia, loss of neural sensitivity, paresis, papillar edema of the eyes, abnormal speech, cerebral edema, delirium, aggressiveness, and psychoses.

制备方法与用途

性质

溴化氰是一种无色固体,剧毒且容易吸潮。其熔点为50-53℃,沸点为61-62℃,易升华。

溴化氰活化

溴化氰活化法是常用的活化方法之一,主要通过生成亚胺碳酸活性基团与伯氨基(NH₂)反应,生成异脲衍生物。这种方法在温和条件下可以与配体结合,且结合量较大。然而,使用溴化氰活化的基质与配体偶联后会生成带有正电荷的异脲衍生物,导致阴离子交换作用和非特异性吸附,从而影响亲和层析的分辨率。此外,由于其不稳定性,在小分子配体的情况下可能会出现脱落现象。另外,溴化氰本身剧毒且易挥发,操作不便。

亲和纯化的实验——活化琼脂糖类产品

目前市场上主要使用溴化氰活化和环氧活化方法。溴化氰活化的优点是载量高、反应速度快,但连接处带有正电荷,可能引起阴离子交换作用,并且结合不够牢固。而环氧活化则结合更稳定,非特异性吸附更低,但载量低,反应速度极慢。

最近市场上出现了CDI(对甲苯磺酰氯)活化的偶联试剂盒产品,这被认为是溴化氰活化的升级版。CDI活化的产品具有更高的载量、更快的反应速度以及更强的结合稳定性,且没有非特异性吸附。这些试剂盒配备了合适的缓冲液和耗材,使得操作变得更为简便快捷。

溴化氰毒性

溴化氰与水或水蒸气接触时会释放剧毒、易燃及腐蚀性的溴化氢和氰化氢气体。不纯物质的存在可能会导致其快速分解并引起爆炸。吸入溴化氰会导致头痛、头晕、恶心、呕吐等症状,严重时可致肺水肿甚至死亡。对眼睛和皮肤有强烈刺激性。口服后会引起口腔和胃的灼伤,可能导致死亡。

燃烧(分解)产物包括氰化氢和溴化氢。与氢氧化钠反应生成氰酸钠,与氨及胺作用生成氨基氰,与醇作用生成三聚氰酸酯。

溴化氰在受热或遇水时会释放剧毒气体,并且遇酸容易引起爆炸。本品不燃,在火场中存在溴化氰的情况下可以用雾状水进行灭火,但需避免水直接接触溴化氰。禁止使用酸碱灭火剂。含氰化物的废水必须经过处理后再排放,并应与酸性废水分开储存以防止氰化氢气体逸出。

用途

  1. 用于支持物琼脂糖凝胶(Sepharose 4B)结合,通过亲和层析法实现纯化或活化。例如:疫苗;单克隆抗体。
  2. 吡啶环的开环反应鉴别,如尼可刹米的鉴别。
  3. 肉与肉制品中的维生素PP含量测定。
  4. 在蛋白质序列测定中断裂肽键(甲硫氨酸侧链的硫醚基),如将免疫球蛋白分解为片段,例如Fc段、Fab段。
