代谢
锰主要通过摄入被吸收,但也可以通过吸入。它在血浆中与α-2-巨球蛋白、白蛋白或转铁蛋白结合,并分布到大脑和所有其他哺乳动物组织,尽管它倾向于在肝脏、胰腺和肾脏中积累更多。锰能够存在于多种氧化状态,并且据信在体内会发生氧化状态的变化。锰的氧化状态可以影响组织的毒物动力学行为,甚至可能影响毒性。锰主要通过粪便排出。(L228)
Manganese is absorbed mainly via ingestion, but can also be inhaled. It binds to alpha-2-macroglobulin, albumin, or transferrin in the plasma and is distributed to the brain and all other mammalian tissues, though it tends to accumulate more in the liver, pancreas, and kidney. Manganese is capable of existing in a number of oxidation states and is believed to undergo changes in oxidation state within the body. Manganese oxidation state can influence tissue toxicokinetic behavior, and possibly toxicity. Manganese is excreted primarily in the faeces. (L228)

毒理性
  • 毒性总结
锰是一种细胞毒素,可以损害运输系统、酶活性和受体功能。它主要针对中枢神经系统,尤其是基底神经节中的苍白球。人们认为,锰离子Mn(II)增强了各种胞内儿茶酚胺的自动氧化或转换,导致自由基、活性氧种和其他细胞毒素代谢产物的产生增加,同时耗尽细胞的抗氧化防御机制,导致氧化损伤和选择性破坏多巴胺能神经元。除了多巴胺,还认为锰会干扰其他神经递质,如GABA和谷氨酸。为了产生氧化损伤,锰必须首先克服抗氧化酶超氧化物歧化酶。Mn(II)的神经毒性还与其在生理条件下替代Ca(II)的能力有关。它可以通过钙单向转运体进入线粒体并抑制线粒体氧化磷酸化。它还可能抑制Ca(II)的外流,这可能导致线粒体膜完整性的丧失。Mn(II)已被证明能显著抑制线粒体顺乌头酸酶活性,改变氨基酸代谢和细胞铁稳态。(L228)
Manganese is a cellular toxicant that can impair transport systems, enzyme activities, and receptor functions. It primarily targets the central nervous system, particularily the globus pallidus of the basal ganglia. It is believed that the manganese ion, Mn(II), enhances the autoxidation or turnover of various intracellular catecholamines, leading to increased production of free radicals, reactive oxygen species, and other cytotoxic metabolites, along with a depletion of cellular antioxidant defense mechanisms, leading to oxidative damage and selective destruction of dopaminergic neurons. In addition to dopamine, manganese is thought to perturbations other neurotransmitters, such as GABA and glutamate. In order to produce oxidative damage, manganese must first overwhelm the antioxidant enzyme manganese superoxide dismutase. The neurotoxicity of Mn(II) has also been linked to its ability to substitute for Ca(II) under physiological conditions. It can enter mitochondria via the calcium uniporter and inhibit mitochondrial oxidative phosphorylation. It may also inhibit the efflux of Ca(II), which can result in a loss of mitochondrial membrane integrity. Mn(II) has been shown to inhibit mitochondrial aconitase activity to a significant level, altering amino acid metabolism and cellular iron homeostasis. (L228)

制备方法与用途

产品描述

硫酸锰(英文名称:Manganese sulphate)常温下为浅粉红色单斜晶系细结晶。它易溶于水,不溶于乙醇,在高温条件下会失去结晶水。具体而言,加热至200℃以上开始失去结晶水,约280℃时失去大部分结晶水,700℃变成无水盐熔融物,而在850℃开始分解并释放出三氧化硫、二氧化硫或氧气。

锰是元素周期表Ⅶ族的元素,在自然界中通常以化合物形式存在于动植物体中。自Orent与Kemmer等发现锰对动物的重要性后,大量研究表明,锰在动物机体中有重要作用。它参与精氨酸激酶、脯氨酸肽酶、丙酮酸竣化酶的重要组成,并能激活多种酶,如部分水解酶、脱坡酶、磷酸化酶和核化酶的活性。锰具有促进生长、增强免疫和提高繁殖性能的作用。

硫酸锰是一种重要的微量元素肥料。作为基肥或浸种、拌种、追肥以及叶面喷洒使用时,可促进作物生长并增加产量。在畜牧业与饲料工业中用作饲料添加剂,有助于畜禽发育良好,并有催肥效果。此外,它也是油漆、油墨催干剂的原料,合成脂肪酸的催化剂,在造纸、陶瓷、印染和矿石浮选领域也具有广泛的应用。

物理性质

硫酸锰的水合物为微红色斜方晶体状。易溶于水而不溶于乙醇,无臭且不可燃,高温下可分解并释放SO3、SO2或氧气。残留物可能含有二氧化锰或四氧化三锰。

应用

硫酸锰作为重要的基础无机盐,在农业中可添加到肥料和饲料中以达到增产、催肥及促进生长的目的;在化工领域,它用于制造各种锰盐,并且还在涂料、造纸、陶瓷、电子、纺织等行业中有广泛应用。

    摘要:
    通过材料表征方法和电化学技术研究了二氧化硒(SeO 2)对从硫酸盐基中性溶液获得的锰涂层的微观结构和电沉积的影响。分别通过扫描电子显微镜(SEM)和粉末X射线衍射光谱(XRD)研究了这些涂层的晶体结构和表面形态。SEM和XRD数据表明,SeO 2可以有效地加速相变,并促进晶粒细化和细化。电化学结果表明SeO 2可以抑制氢的释放反应并促进锰的沉积。发现二氧化硒在锰沉积中的作用是还原和吸附机理。该过程的解释如下:首先,将Se(IV)还原为Se(0),然后将Se(0)的一部分还原为硒化物,然后与其余的Se(0)结合形成复杂的化合物(多-硒离子)。

    Enzymatic and chiral HPLC resolution of α-azido acids and amides
    摘要:
    For the first time, enzymatic resolution of alpha-azido acid amides has been successfully demonstrated with high yields and enantiomeric excess. In one case dynamic kinetic resolution was achieved leading to more than 50% yield of the enantiomerically pure azido acid. Chiral HPLC was also used to separate racemic alpha-azido acids and the separation process was automated. Two routes to enantiopure alpha-azido acid building blocks for solid-phase peptide synthesis have, therefore, been established. (C) 2000 Elsevier Science Ltd. All rights reserved.
