代谢
二硫化碳(CS2)的内皮损伤伴发甲状腺功能减退的代谢可能涉及直接损伤内皮,并与甲状腺功能减退有关,因为硫代氨基甲酸盐(硫脲),一种强烈的抗甲状腺物质,是CS2的主要尿液代谢物。
The metabolism for CS2-atheroma production also may involve direct injury to the endothelium coupled with hypothyroidism, because thiocarbamate (thiourea), a potent antithyroid substance, is a principal urinary metabolite of CS2.

代谢
氮酶能还原二硫化碳,同时也能被这种毒素抑制。二硫化碳(以AL CS2的形式)主要与血红蛋白结合,在较小程度上与其他血液蛋白如白蛋白和γ-球蛋白结合。二硫化碳通过细胞色素P-450生物激活为不稳定氧中间体。这个中间体可能自发降解为原子硫和碳酰基硫化物,或者水解形成原子硫和硫代碳酸。在这些反应中产生的原子硫可以与高分子共价结合,或者被氧化成硫酸盐等产物。形成的碳酰基硫化物可以通过碳酸酐酶转化为硫代碳酸。硫代碳酸可以进一步自发降解,再生碳酰基硫化物或形成二氧化碳和硫氢化物离子(HS-)。形成的HS-随后可以被氧化成硫酸盐或其他非挥发性代谢物。二硫代碳酸酯是二硫化碳与氨基酸反应的产物。吸收的大部分二硫化碳都被代谢了。尿液中可以发现微量的未改变的二硫化碳。二硫化碳或碳酰基硫化物可以与内源性谷胱甘肽结合,分别产生噻唑烷-2-硫酮-4-羧酸和2-氧噻唑烷-4-羧酸。碳酸酐酶2介导二硫化碳的代谢。(L592, A207, A208, A210, A211, A212)
Nitrogenase reduces carbon disulfide and can also be inhibited by this toxin. Carbon disulfide binds (in the form of AL CS2) mainly to hemoglobin and to a small extent to other blood proteins, such as albumin and gamma-globulin. Carbon disulfide is bioactivated by cytochrome P-450 to an unstable oxygen intermediate. The intermediate may either spontaneously degrade to atomic sulfur and carbonyl sulfide or hydrolyze to form atomic sulfur and monothiocarbonate. The atomic sulfur generated in these reactions may either covalently bind to macromolecules or be oxidized to products such as sulfate. The carbonyl sulfide formed may be converted to monothiocarbonate by carbonic anhydrase. Monothiocarbonate may further spontaneously degrade, regenerating carbonyl sulfide or forming carbon dioxide and sulfide bisulfide ion (HS-). The HS- formed can subsequently be oxidized to sulfate or other nonvolatile metabolites. Dithiocarbamates are the products of the reaction of carbon disulfide with amino acids. Most of the carbon disulfude absorbed is metabolized. Small traces of unchanged can be found in the urine. Carbon disulfide or carbonyl sulfide can conjugate with endogenous glutathione to yield thiazolidine-2-thione-4-carboxylic acid and 2-oxythiazolidine-4-carboxylic acid, respectively. Carbonic anhydrase 2 mediates the metabolism of carbon disulfide. (L592, A207, A208, A210, A211, A212)

IDENTIFICATION AND USE: Carbon disulfide is a clear colorless liquid at room temperature. It is used in the production of viscose fiber and cellophane film. HUMAN STUDIES: The most important health effects for carbon disulfide are coronary heart disease, retinal angiopathy, color discrimination, effects on peripheral nerves, psychophysiological effects, morphological and other central nervous system (CNS) effects, and fertility and hormonal effects. No evidence of carcinogenicity has been observed in epidemiological studies. There are several reports of decreased libido and or impotence among males occupationally exposed to high concentrations of carbon disulfide. Reproductive health hazards for women chronically exposed to carbon disulfide in the workplace are the following: menstrual disorders are more frequent than in the case of the healthy women, the average menopausal age is statistically earlier, and complex disturbances in neurohormonal system including diminished secretion of estrogens and progesterone in ovaries and dehydroepiandrosterone sulfate in the adrenal gland. DNA damage in human buccal cells of workers occupationally long-term exposed to carbon disulfide was monitored with comet assay, and the possibility of DNA damage was significantly higher in exposure group than that in control group. In human sperm exposed to carbon disulfide in vitro, there was a significant increase in the frequency of chromosomal aberrations and in the frequency of chromosomal breaks. ANIMAL STUDIES: Neurological effects such as hind-limb motor difficulties, reduced nerve conduction velocity, and degeneration of nerve fibers were seen in rats exposed to 700 ppm of carbon disulfide for 5 hours a day, 5 days a week, for 12 weeks. Other behavioral effects in rats included decreased responsiveness to a visual stimulus and mild tremors, reactivity in response to handling was increased, and excitability in the open field was decreased. No evidence of carcinogenicity has been reported in long term studies with laboratory animals. Carbon disulfide was not mutagenic to Salmonella typhimurium strains TA98 and TA100 at 300 to 1000 umol nor to Escherichia coli strain WP2 uvrA at 20 to 600 umol with or without metabolic activation, nor in Drosophila melanogaster at 200 to 800 ppm. However, DNA damage in mice sperm was detected with single-cell gel electrophoresis assay. In experimental animals, carbon disulfide is embryotoxic and fetotoxic at high concentrations and is teratogenic at exposure levels toxic to the dam. ECOTOXICITY STUDIES: Reduced hatching and developmental effects, particularly notochord deformities, were observed in the frog Microhyla ornata exposed to carbon disulfide.

Carbon disulfide is a potent nerve toxin and also affect liver enzymes, particularly those related to lipid metabolism. The increases in serum cholesterol that are sometimes seen following carbon disulfide exposure may be a result of increased hepatic cholesterol synthesis. The primary target of carbon disulfide appears to be the nervous system. Neurophysiological and behavioral effects as well as pathomorphology of peripheral nervous system structures have been reported in humans. Moreover, carbon disulfide metabolites of the thiocarbamate type inhibit aldehyde anhydrase. (L592, A215)

    A unified approach to access Nβ-protected amino alkyl isothiocyanates using Nβ-protected amino alkyl azides through a general strategy of Staudinger/aza-Wittig reaction is described. The type of protocol used to access isothiocyanates depends on the availability of precursors and also, especially in the amino acid chemistry, on the behavior of other labile groups towards the reagents used in the protocols;
    一种统一的方式来访问Ñ β -保护的氨基烷基异硫氰酸酯使用Ñ β描述了通过Staudinger / aza-Wittig反应的一般策略保护的氨基烷基叠氮化物。用于获得异硫氰酸酯的方案的类型取决于前体的可用性,尤其是在氨基酸化学中,还取决于其他不稳定基团对方案中所用试剂的行为。幸运的是,我们并不担心这两个因素,因为通过标准方案可以轻松制备前体叠氮化物,并且本方案可以为访问标题化合物铺平道路,而不会影响Boc,Cbz和Fmoc保护基以及苄基和叔丁基。侧链。本策略消除了使用胺来获得标题化合物的需要,因此,该方法是分步经济的。其他优点包括保留手性,方便处理和易于纯化。还制备了一些迄今未报告的化合物,所有最终化合物均通过IR,质量,旋光度和1 H和13 C NMR研究。

    7-dimethoxy-4-quinazolinyl)piperidines carrying substituted hydantoin and 2-thiohydantoin rings was synthesized and examined for cardiotonic activity in anesthetized dogs. Introduction of isopropyl and sec-butyl group at the 5-position of the hydantoin and thiohydantoin rings led to potent inotropic activity. Effects of insertion of an alkyl chain between the piperidine and the hydantoin rings were
    合成了一系列带有取代的乙内酰脲和2-巯基乙内酰脲环的新颖的1-(6,7-二甲氧基-4-喹唑啉基)哌啶,并在麻醉的狗中检查了其强心活性。在乙内酰脲和硫代乙内酰脲环的5-位上引入异丙基和仲丁基导致有效的变力活性。还检查了哌啶和乙内酰脲环之间烷基链插入的影响。研究了该系列中最佳强心活动所需的结构要求。
