ADMET

代谢
通过肺部、胃肠系统和皮肤被吸收。由于它是维生素B12(胺)的一个组成部分,因此它被分配到身体的多数组织中。它在血液中运输,通常与白蛋白结合,肝和肾中含量最高。主要通过尿液和粪便排出。
Cobalt is absorbed though the lungs, gastrointestinal tract, and skin. Since it is a component of the vitamin B12 (cyanocobalamin), it is distributed to most tissues of the body. It is transported in the blood, often bound to albumin, with the highest levels being found in the liver and kidney. Cobalt is excreted mainly in the urine and faeces. (L29)

  • 毒性总结
识别和使用:双(2-乙基己酸)是一种蓝色液体。它用作油漆干燥剂、增白剂、催化剂。人类暴露和毒性:已经发表了职业性接触过敏性接触性皮炎的病例报告,由-2-乙基己酸盐引起。动物研究:将2-乙基己酸盐滴入兔子的眼睛后,两只雌性动物在处理24小时后角膜出现轻微混浊,并持续到处理72小时后。2-乙基己酸盐在小鼠淋巴瘤细胞中进行了诱导突变能力的检测,突变位点是次黄嘌呤-鸟嘌呤磷酸核糖转移酶(hprt)(6-硫鸟嘌呤[6TG]抗性)。这项研究的结果是阴性的。
IDENTIFICATION AND USE: Cobalt bis(2-ethylhexanoate) is a blue liquid. It is used as paint drier, whitener, catalyst. HUMAN EXPOSURE AND TOXICITY: Case reports of occupational allergic contact dermatitis caused by cobalt-2-ethylhexoate have been published. ANIMAL STUDIES: The instillation of cobalt 2-ethylhexanoate into the eye of rabbits resulted in slight opacity of the cornea in the two female animals 24 hours after treatment and persisted until 72 hours after treatment. Cobalt 2-ethyl hexanoate was assayed for the ability to induce mutation at the hypoxanthine-guanine phosphoribosyl transferase (hprt) locus (6-thioguanine [6TG] resistance) in mouse lymphoma cells. The results of this study were negative.

毒理性
  • 毒性总结
被认为通过氧化剂和自由基过程表现出其毒性。它产生氧自由基,并可能被氧化成离子态的,导致脂质过氧化增加、DNA损伤,并诱导某些酶,导致细胞凋亡。还被证明可以阻断无机通道,可能损害神经传递。还可以与辛酸螯合,损害丙酮酸脂肪酸的氧化。此外,可能通过与指DNA修复蛋白相互作用来抑制DNA修复,并且已被证明可以抑制血红素合成和葡萄糖代谢。可能激活特定的辅助性T淋巴细胞,并直接与免疫蛋白(如抗体IgA和IgE或Fc受体)相互作用,导致免疫致敏。
Cobalt is believed to exhibit its toxicity through a oxidant-based and free radical-based processes. It produces oxygen radicals and may be oxidized to ionic cobalt, causing increased lipid peroxidation, DNA damage, and inducing certain enzymes that lead to cell apoptosis. Cobalt has also been shown to block inorganic calcium channels, possibly impairing neurotransmission. Cobalt can also chelate lipoic acids, impairing oxidation of pyruvate or fatty acids. In addition, cobalt may inhibit DNA repair by interacting with zinc finger DNA repair proteins, and has also been shown to inhibit heme synthesis and glucose metabolism. Cobalt may activate specific helper T-lymphocyte cells and interact directly with immunologic proteins, such as antibodies (IgA and IgE) or Fc receptors, resulting in immunosensitization. (L29)
