代谢
砒霜主要通过吸入或摄入被吸收,较少程度上通过皮肤接触。然后它被分布到全身,如果需要,它会被还原成亚砷酸盐,然后通过亚砷酸盐甲基转移酶甲基化成单甲基MMA)和二甲基硅酸DMA)。砒霜及其代谢物主要通过尿液排出。已知砒霜能诱导属结合蛋白蛋白,通过绑定砒霜和其他属并使其生物活性失效,以及作为抗氧化剂的作用,从而减少砒霜和其他属的有毒效果。
Arsenic is absorbed mainly by inhalation or ingestion, as to a lesser extent, dermal exposure. It is then distributed throughout the body, where it is reduced into arsenite if necessary, then methylated into monomethylarsenic (MMA) and dimethylarsenic acid (DMA) by arsenite methyltransferase. Arsenic and its metabolites are primarily excreted in the urine. Arsenic is known to induce the metal-binding protein metallothionein, which decreases the toxic effects of arsenic and other metals by binding them and making them biologically inactive, as well as acting as an antioxidant.

毒理性
  • 毒性总结
砒霜及其代谢物通过多种机制干扰ATP的产生。在柠檬酸循环层面,砒霜抑制了丙酮酸脱氢酶,并通过与磷酸竞争解耦了氧化磷酸化,从而抑制了与能量相关的NAD+还原、线粒体呼吸和ATP合成。过氧化氢的产生也增加了,这可能会形成活性氧物种和氧化应激。砒霜的致癌性受到砒霜与微管蛋白结合的影响,导致非整倍体、多倍体和有丝分裂停滞。其他砒霜蛋白靶点的结合也可能导致DNA修复酶活性改变、DNA甲基化模式改变和细胞增殖。
Arsenic and its metabolites disrupt ATP production through several mechanisms. At the level of the citric acid cycle, arsenic inhibits pyruvate dehydrogenase and by competing with phosphate it uncouples oxidative phosphorylation, thus inhibiting energy-linked reduction of NAD+, mitochondrial respiration, and ATP synthesis. Hydrogen peroxide production is also increased, which might form reactive oxygen species and oxidative stress. Arsenic's carginogenicity is influenced by the arsenical binding of tubulin, which results in aneuploidy, polyploidy and mitotic arrests. The binding of other arsenic protein targets may also cause altered DNA repair enzyme activity, altered DNA methylation patterns and cell proliferation. (T1, A17)

  • 健康影响
砒霜中毒可能导致多系统器官衰竭而死亡,可能是由于细胞坏死而非凋亡。砒霜也是一种已知的致癌物,尤其是在皮肤癌、肝癌、膀胱癌和肺癌中。
Arsenic poisoning can lead to death from multi-system organ failure, probably from necrotic cell death, not apoptosis. Arsenic is also a known carcinogen, esepcially in skin, liver, bladder and lung cancers. (T1, L20)

  • Reaction of hexafluoroacetone with some arsenic compounds

    日期:1965.8
    Hexafluoroacetone reacts with the arsines (CH3)2AsH and CH3AsH2 to give the compounds (CH3)2AsC(CF3)2OH and CH3(H)AsC(CF3)2OH respectively. The ketone also forms a fairly easily dissociated 1:1 complex with tetramethyldiarsine which reacts with hexafluoro-2-butyne to give a high yield of cis-(CH3)2AsC(CF3C(CF3)As(CH3)2. A cyclic structure is suggested for the complex.

    Reaction of the labile clusters Os3(CO)11(NCME) (1) with primary arsines (RAsH2; R = Ph, Me, H) yields the arsinidene compounds H2Os2(CO)11(μ3-AsR) (2a: R = Ph; 2b: R = Me; 2c: R = H) in which the cluster framework consists of an HOs(CO)4 and an HOs2(CO)7 unit linked together by a μ3-AsR group. The 1H NMR spectra of 2a2c reveal the presence of two isomers in each case. At elevated temperatures, 2a

    reaction of THB with HCl, H2SO4, and HClO4, while HG from CH3COOH or TRIS buffer after prereduction with l-cysteine resulted in the formation of only the corresponding hydrides. In the case of HNO3 formation of corresponding hydrides was preserved for MAsV and DMAsV but not for TMAsVO. The extent of demethylation strongly depends on concentration of the acid and THB. It can be strongly suppressed in
