代谢
通过口服含有卤代烯基或卤代烷基取代基的几种促突变剂和致癌剂的鼠类会排泄少量尿液中的2-卤代丙烯酸,这些酸以它们的五氟苯甲酯形式进行分析,例如从三异丙酯中得到的2-氯丙烯酸和三氯丙烯酸。兔肝微粒体氧化酶也能从三异丙酯中产生2-氯丙烯酸和三氯丙烯酸。2-卤代丙烯醛作为强突变剂和中间代谢物可能有助于三异丙酯的不良毒理学特性。
Rats treated orally with several promutagens and carcinogens containing haloallyl or halopropyl substituents excrete small amount of urinary 2-haloacrylic acids, analyzed as their pentafluorobenzyl esters, such as 2-chloroacrylic acid and trichloroacrylic acid from triallate. Rabbit liver microsomal oxidases also yield 2-chloroacrylic and trichloroacrylic acids from triallate. 2-Haloacroleins as potent mutagens and intermediary metabolites may contribute to adverse toxicological properties of triallate.

主要的(产率57-83%)小鼠微粒体混合功能氧化酶对(E)和(Z)二醋酸酯和三醋酸酯的代谢产物,通过高效液相色谱共色层析鉴定为相应的亚砜。通过顶空气相色谱/质谱(GLC/MS)鉴定的其他混合功能氧化酶代谢产物,并通过气相色谱/电子捕获检测器(GLC/ECD)定量,包括来自二醋酸酯的21-氯丙烯醛(Z异构体产率为9.2%,E异构体产率为1.6%)和亚磺酸酯(产率为0.3%)以及来自三醋酸酯的2,3-三氯丙烯醛。向混合功能氧化酶系统中加入谷胱甘肽和谷胱甘肽S-转移酶,会减少亚砜的量并产生新的产物,通过顶空气相色谱/电子捕获检测器(GLC/ECD)和气相色谱/质谱(GLC/MS)鉴定为来自(E)和(Z)二醋酸酯的2,3-二氯丙烯基硫醇和来自三醋酸酯的2,3,3-三氯丙烯基硫醇,它们还使亚磺酸酯释放的2-氯丙烯基硫醇增加了9倍。因此,形成致突变氯丙烯醛的过程主要涉及(E)和(Z)二醋酸酯的亚砜化,随后发生(2,3)σ迁移重排-1,2-消除反应,以及三醋酸酯和亚磺酸酯的S-亚甲基羟基化,然后是其α-羟基中间体的分解。与谷胱甘肽竞争的谷胱甘肽S-转移酶催化的共轭作用,将亚砜化中间体从涉及氯丙烯醛形成的活化转向通过氯丙烯基硫醇释放的解毒。
The major (57-83% yields) mouse microsomal mixed function oxidase metabolites of (E) and (Z) diallate and triallate are identified by HPLC cochromatography as the corresponding sulfoxides. Other mixed function oxidase metabolites identified by headspace GLC/MS and quantitated by GLC/ECD are 21-chloroacrolein from diallate (9.2% and 1.6% from the Z and E isomers, respectively) and sulfallate (0.3% yield) and 2,3-trichloracrolein from triallate. Addition of glutathione and glutathione S-transferase to the mixed function oxidase system reduces the amounts of sulfoxides and yields new products identified by headspace GLC/ECD and GLC/MS as 2,3-dichlorallylthiol from (E) and (Z) diallate and 2,3,3-trichlorallylthiol from triallate, they also increase by 9 fold the liberation of 2-chloroallythiol from sulfallate. Thus, formation of mutagenic chloroacroleins involves primarily sulfoxidation of (E) and (Z) diallate followed by (2,3) sigmatropic rearrangement-1,2-elimination reactions and S-methylene hydroxylation of triallate and sulfallate and then decomposition of their alpha-hydroxy intermediates. Competing glutathione S-transferase catalyzed conjugations with glutathione divert the sulfoxidized intermediates from activation involving chloroacrolein formation to detoxification on chloroallylthiol liberation.

(13)C, (14)C 三氯乙酸盐通过口服给药给Sprague Dawley大鼠。在排泄物中鉴定出12种代谢物,其中最丰富的是2,3,3-三氯-2-丙烯磺酸。从2,3,3-三氯-2-丙烯硫醇衍生出的五种代谢物在排泄物中被鉴定出来,包括一种甲基磺酰巯基尿酸,其结构通过X射线晶体学得到确认。还鉴定出三种2-氯丙烯酸代谢物,包括一种2-氯丙烯酸巯基尿酸,其结构通过X射线晶体学得到确认。2,3,3-三氯-2-丙烯醇和羟基三氯乙酸盐也被鉴定为代谢物。将放射性标记的巯基和磺酸分别给不同的动物,巯基给药的大鼠尿液中仅排泄出巯基衍生的代谢物,而磺酸给药的大鼠则排泄出磺酸和磺酸。在大鼠中,三氯乙酸盐的代谢主要通过三条途径进行,即S-氧化生成硫酸,S-氧化/水解/还原生成巯基衍生物,以及2,3,3-三氯丙烯硫醇基团的C-氧化。因此,在大鼠中,形成易于排泄的硫酸和巯基衍生物是三氯乙酸盐代谢的主要途径。
(13)C, (14)C Triallate was administered orally to Sprague Dawley rats. Twelve excreted metabolites were identified, the most abundant being 2,3,3-trichloro-2-propenesulfinic acid. Five metabolites derived from 2,3,3-trichloro-2-propenethiol were identified in excreta, including a methyl sulfone mercapturate whose structure was confirmed by X-ray crystallography. Three 2-chloroacrylate metabolites were identified, including a 2-chloroacrylate mercapturate whose structure was confirmed by X-ray crystallography. 2,3,3-Trichloro-2-propenol and hydroxytriallate were also identified as metabolites. Dosing of radiolabeled thiol and sulfinic acid to separate animals resulted in excretion of only thiol derived metabolites in the urine of thiol dosed rats, while sulfinic acid and sulfonic acid were excreted by sulfinic acid dosed rats. Triallate metabolism in rats proceeds via three main pathways, ie, S-oxidation leading to sulfur acids, S-oxidation/hydrolysis/reduction leading to thiol derivatives, and C-oxidation of the 2,3,3-trichloropropenethiol moiety. Thus, formation of readily excreted sulfur acids and thiol derivatives is the major route of triallate metabolism in rats.

大鼠肝脏酶制剂被用来研究三异丙酯代谢的机理途径。将含有还原型烟酰胺腺嘌呤二核苷酸磷酸的微囊与(14)C三异丙酯一起培养,产生了通过多种反应类型生成的代谢物,包括硫氧化/水解和对烯丙基硫醇基团的羟基化伴随着重排。向微囊培养物中加入谷胱甘肽,导致了谷胱甘肽共轭物的形成,这是通过谷胱甘肽对三氯丙烯等代谢中间体的共轭加成而产生的。向微囊培养物中加入谷胱甘肽抑制了三异丙酯衍生放射性物质与微囊蛋白的结合。通过质谱、化学合成以及异核多量子相干NMR光谱的新应用完成了代谢物的鉴定。
Rat liver enzyme preparations were used to investigate the mechanistic pathways of triallate metabolism. Incubation of (14)C triallate with reduced nicotinamide adenine dinucleotide phosphate fortified microsomes gave rise to metabolites generated via a number of reaction types, including sulfur oxidation/hydrolysis and hydroxylation of the allylic thiol moiety accompanied by rearrangement. Addition of glutathione to microsomal incubations resulted in the formation of glutathione conjugates arising via conjugate addition of glutathione to metabolic intermediates such as trichloroacrolein. Addition of glutathione to microsomal incubations inhibited the binding of triallate derived radioactivity to microsomal proteins. Metabolite identification was accomplished by mass spectrometry and chemical synthesis and by a novel application of heteronuclear multiple quantum coherence NMR spectroscopy.

代谢
一般来说,硫代氨基甲酸盐可以通过皮肤、粘膜以及呼吸和消化系统吸收。它们主要通过呼出气体和尿液迅速排出体外。哺乳动物中硫代氨基甲酸盐的代谢有两个主要途径。一个是通过亚磺酰化并与谷胱甘肽结合。结合产物随后裂解为半胱氨酸衍生物,该衍生物被代谢为巯基尿酸化合物。第二个途径是硫氧化为亚磺酰化物,然后进一步氧化为磺酰化物,或者经羟基化转变为进入碳代谢池的化合物。
As a general rule, thiocarbamates can be absorbed via the skin, mucous membranes, and the respiratory and gastrointestinal tracts. They are eliminated quite rapidly, mainly via expired air and urine. Two major pathways exist for the metabolism of thiocarbamates in mammals. One is via sulfoxidation and conjugation with glutathione. The conjugation product is then cleaved to a cysteine derivative, which is metabolized to a mercapturic acid compound. The second route is oxidation of the sulfur to a sulfoxide, which is then oxidized to a sulfone, or hydroxylation to compounds that enter the carbon metabolic pool.

识别和使用:草达灭是一种从深棕色到黄色的固体(>30°C时为清澈棕色到深棕色的液体)。它是一种选择性除草剂,用于控制小麦中的野燕麦。人体研究:草达灭未能在人类细胞中诱导非计划性DNA合成。流行病学研究未在高草达灭暴露后发现神经功能有显著变化。动物研究:在兔子上,它对皮肤有高度刺激性,对眼睛有轻微刺激性。每天给母鸡喂食草达灭10天,母鸡的生育力下降,并在肝脏、肾脏和生殖器官中诱导出血和退行性坏死性变化。给小鼠口服945 mg/kg草达灭和给兔500 mg/kg草达灭,降低了大脑乙酰胆碱酯酶活性和外周血液中的红细胞数量。当以300 mg/kg给羊服用时,它降低了血液血清中的天冬氨酸转氨酶活性,并增加了丙氨酸转氨酶活性。在给猪服用草达灭后,发现外周血RNA减少。观察到脑出血、局部肝细胞坏死和脾脏增生。草达灭在兔子上略微抑制了血液胆碱酯酶和脑胆碱酯酶。在莱杭鸡上进行神经毒性测试时,草达灭在300 mg/kg/day的局部给药或400 mg/kg/day的口服给药下并未引起神经毒性的迹象。羊可能会因300 mg/kg的草达灭中毒,表现出抑郁、厌食、流涎、虚弱、抽搐和轻瘫的症状。草达灭在母羊中产生了内分泌变化,并显著增加了输卵管上皮内囊肿的严重程度。在小鼠上的长期研究描述了两种性别中的肝细胞癌和雄性中的肝脏血管肉瘤。在大鼠的发育研究中注意到胎儿体重减少和骨骼变异。在沙门氏菌typhimurium上进行诱变性测试时,对于TA-1535和TA-100菌株以及有或没有活化的情况下,以及对于TA 98有活化的情况下,都存在阳性反应。生态毒性研究:对大型蚤和水蚤的静态急性毒性测试表明,草达灭对水生无脊椎动物非常有毒。
IDENTIFICATION AND USE: Triallate is a dark brown to yellow solid (>30 °C clear brown to dark brown liquid). It is a selective herbicide for control of wild oats in wheat. HUMAN STUDIES: Triallate did not induce unscheduled DNA synthesis in human cells. Epidemiological study did not find significant changes in neurological function after high triallate exposure. ANIMAL STUDIES: It was highly irritating to skin, and slightly irritating to eyes in rabbits. Hens fed triallate daily for 10 days had decreased fertility and induced hemorrhaging and degenerative necrotic changes in liver, kidneys, and reproductive organs. Oral administration of 945 mg/kg triallate to mice and 500 mg/kg to rabbits decreased brain acetylcholinesterase activity and the number of erythrocytes in peripheral blood. When given to sheep at 300 mg/kg, it decreased aspartate aminotransferase and increased alanine aminotransferase activities in blood serum. A decrease in peripheral blood RNA was found in pigs given triallate. Brain hemorrhages, focal hepatic cell necrosis and splenic hyperplasia were observed. Triallate inhibited blood cholinesterase and brain cholinesterase slightly in rabbits. When tested for neurotoxicity in Leghorn hens, triallate did not elicit signs of neurotoxicity at 300 mg/kg/day topically or 400 mg/kg/day orally. Sheep may be poisoned by 300 mg/kg of triallate, showing signs of depression, anorexia, salivation, weakness, convulsions and paresis. Triallate produced endocrine changes in ewes and caused a significant increase in severity of oviductal intraepithelial cysts. Long-term studies in mice described hepatocellular carcinoma in both sexes and liver hemangiosarcoma in males. Reduced fetal weight and skeletal variation were noted in developmental studies in rats. When tested for mutagenicity in Salmonella typhimurium, a positive response was present for strains TA-1535 and TA-100 with and without activation and for strain TA 98 with activation. ECOTOXICITY STUDIES: Static acute toxicity tests with Daphnia magna and Chironomus riparius suggested that triallate was very toxic to aquatic invertebrates.

  • 毒性总结
草甘膦、敌草隆和磺草灵的代谢产物似乎具有诱变或致癌性。特别是,2-氯代烯丙基团对这些除草剂的诱变活性负有责任。这些代谢物可能通过与DNA结合或破坏DNA导致碱基对替换。已经证明敌草隆在小鼠中是一种致癌物。一些硫代氨基甲酸盐(EPTC、 Molinate、Pebulate和Cycloate)具有共同的毒性机制,即抑制乙酰胆碱酯酶。乙酰胆碱酯酶抑制剂抑制乙酰胆碱酯酶的作用。由于其基本功能,干扰乙酰胆碱酯酶作用的化学物质是强效的神经毒素,在低剂量下会导致过度流涎和流泪。头痛、流涎、恶心、呕吐、腹痛和腹泻在高剂量暴露时常常很明显。乙酰胆碱酯酶分解神经递质乙酰胆碱,该神经递质在神经和肌肉接头处释放,以允许肌肉或器官放松。乙酰胆碱酯酶抑制的结果是乙酰胆碱积聚并继续发挥作用,使得任何神经冲动不断传递,肌肉收缩不会停止。
The metabolic products of triallate, diallate and sulfallate appear to be mutagenic or carcinogenic. In particular, the 2-chloro-allyl group is responsible for the mutagenicity of these herbicides. These metabolites likely bind to or disrupt DNA causes base-pair subsitutions. Diallate has been shown to be a carcinogen in mice. Some thiocarbamates (EPTC, Molinate, Pebulate, and Cycloate) share a common mechanism of toxicity, i.e. the inhibition of acetylcholinesterase. An acetylcholinesterase inhibitor suppresses the action of acetylcholine esterase. Because of its essential function, chemicals that interfere with the action of acetylcholine esterase are potent neurotoxins, causing excessive salivation and eye-watering in low doses. Headache, salivation, nausea, vomiting, abdominal pain and diarrhea are often prominent at higher levels of exposure. Acetylcholine esterase breaks down the neurotransmitter acetylcholine, which is released at nerve and muscle junctions, in order to allow the muscle or organ to relax. The result of acetylcholine esterase inhibition is that acetylcholine builds up and continues to act so that any nerve impulses are continually transmitted and muscle contractions do not stop.

制备方法与用途

毒性 大鼠急性经口LD₅₀为1675~2165 mg/kg(平均约1800 mg/kg),家兔急性经皮LD₅₀为2225~4050 mg/kg。大鼠喂养2年无作用剂量为200 mg/kg。对兔眼睛有轻度刺激,对皮肤有中等刺激性。在动物体内蓄积作用中等。Ames试验结果为阴性。国外报道该物质在Ames试验(TA₁₅₃₅、TA₉₈、TA₁₀₀)中有轻度诱变作用,高剂量组(1/5 LD₅₀)可导致小鼠骨髓细胞微核率增高。在实验条件下对大鼠和家兔无致畸或致癌作用。虹鳟鱼LC₅₀为1.2 mg/L (96h),鹌鹑急性经口LD₅₀为2251 mg/kg。

化学性质 本品为琥珀色油状液体,熔点29~30℃,沸点约148~149℃/1.199×10³ Pa,蒸气压15.99×10⁻³ Pa (25℃),相对密度1.273(25℃)。能溶于丙酮、乙醇、苯、甲苯等多种有机溶剂,水中溶解度为4 mg/L。对光稳定,无腐蚀性。

用途 野麦畏是一种选择性的土壤处理剂,适用于防除野燕麦,尤其在大麦和小麦田中效果显著。它通过杂草芽鞘或第一片子叶吸收药剂后,影响细胞的蛋白质合成和有丝分裂,抑制细胞伸长,使杂草未出土即死亡。可用于多种作物如油菜、豌豆、亚麻、甜菜、青梨和大豆等,建议用量为8~16 g有效成分/100 m²,并与土壤充分混合施用。

生产方法 将二异丙胺加入氢氧化钠溶液中,搅拌冷却至0-5℃,通入二硫化碳直至完成计算量。随后加入1,1',2,3-四氯丙烯,在0-65℃反应6小时后冷却静置分层。上层为母液,下层粗产品减压蒸馏除去低沸物后得到野麦畏。原料消耗定额:二异丙胺(96%)300 kg/t、四氯丙烯(80%)600 kg/t、氯气600 kg/t。

另一种生产方法如下:将3 g氢氧化钠溶于20 mL水中,与5.5 g (98%)二异丙胺混合后冷却至0~5℃。在搅拌下通入氧硫化碳气体约3 g左右,产生大量结晶,保温反应后继续投入18 g (70%) 1,1',2,3-四氯丙烯,在0~65℃条件下反应6小时。冷却静置分层,将下层粗产品减压蒸馏除去低沸物后得到琥珀色黏稠状液体即为野麦畏。
