Urine treatment with beta-glucuronidase before analysis indicated that significant amounts of the alcohols were excreted as glucuronides, esp isobutyl alcohol. 2-Propanol and 2-butanol were the slowest to be metabolized. When mixtures of alcohols were given, the concentrations of isobutyl alcohol glucuronides were high with the mixtures containing 5 and 15% ethanol, and decreased at 40% ethanol.

毒理性
  • 毒性总结
识别与用途:异丁醇是一种无色、油状液体,具有穿透性、类似葡萄酒的令人不愉快的气味和甜美的威士忌口味。异丁醇是用于表面涂料、粘合剂、药品、杀虫剂、香精和香料的溶剂。它被用作合成树脂的中间体。在美国,异丁醇目前没有被注册用作杀虫剂,但批准的杀虫剂用途可能会定期更改,因此必须咨询联邦、州和地方当局以获取当前批准的用途。人类暴露与毒性:异丁醇在吸入、皮肤或口服暴露后迅速被吸收。一般来说,急性暴露于较高醇类主要会导致中枢神经系统抑制、低血压、恶心、呕吐和腹泻。如果吸入,可能会出现出血性肺炎。眼睛暴露于蒸汽或液体可能会导致灼烧感、流泪、视力模糊和角膜出现空泡。有报道称,在处理丁醇异丁醇后,有3例严重眩晕的病例。动物研究:小鼠反复吸入2125 ppm的异丁醇并未导致死亡。大鼠对中到高浓度的异丁醇反复暴露有很好的耐受性。在一项为期90天的吸入研究中,仅在暴露期间观察到对外部刺激的反应减少。反复暴露并没有加剧这些短暂的影响。根据功能性观察电池(FOB)、定量运动活动、神经病变和计划控制操作性行为终点,没有神经毒性的证据。一项为期13周的口服灌胃研究,使用异丁醇,导致1000 mg/kg bw/day剂量组的活动减少、共济失调和流涎。活动减少和共济失调在研究的第4周得到解决。此外,在13周研究的头两周,1000 mg/kg bw/day剂量组观察到体重增加和饲料消耗的轻微减少。一项吸入、两代生殖毒性研究,使用异丁醇(最高2500 ppm),在两代全身暴露下,并未导致亲代系统性、生殖性或新生儿毒性。在终身研究中,通过灌胃或皮下注射给予异丁醇的大鼠,与对照组相比,总肿瘤发生率增加,包括肝细胞癌、脾肉瘤、前胃癌和骨髓性白血病。在大鼠和兔子的妊娠期间通过吸入暴露于10,000 mg/cu m异丁醇,未观察到不良发育影响。当大肠杆菌CA274未经代谢激活处理0.7%异丁醇时,显示出反向突变的增加率。此外,异丁醇在体内小鼠微核研究中呈阴性。生态毒性研究:美洲龙虾(Homarus americanus)通过向腹部窦注射异丁醇迅速且可重复地被麻醉。异丁醇促进了小麦根在白光下的细胞伸长和总生长;更高浓度抑制了分生组织活动。
IDENTIFICATION AND USE: Isobutyl alcohol is colorless, oily liquid with a penetrating, wine-like, disagreeable odor and sweet whiskey taste. Isobutyl alcohol is a solvent for surface coatings , adhesives, pharmaceuticals, pesticides, flavor, and fragrance. It is employed as an intermediate for synthetic resins. Not registered for current pesticide use in the U.S., but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses. HUMAN EXPOSURE AND TOXICITY: Isobutyl alcohol is rapidly absorbed following inhalation and dermal or oral exposures. In general, acute exposure to higher alcohols results primarily in CNS depression, hypotension, nausea, vomiting, and diarrhea. If aspirated, hemorrhagic pneumonitis may be noted. Eye exposure to vapors or liquid may result in burning, lacrimation, blurring of vision, and vacuoles in the cornea. There is a report of 3 cases with severe vertigo after handling butanol and isobutyl alcohol. ANIMAL STUDIES: Repeated inhalation by mice of 2125 ppm caused no deaths. Repeated exposures to moderate to high concentrations of isobutyl alcohol are well tolerated in rats. In a 90-day inhalation study, a reduced response to an external stimulus was noted in the exposed animals only during the exposure period. Repeated exposures did not exacerbate these transient effects. There was no evidence of neurotoxicity based on functional observational battery (FOB), quantitative motor activity, neuropathy and scheduled-controlled operant behavior endpoints. A 13-week oral gavage study conducted with isobutanol resulted in hypoactivity, ataxia and salivation in the 1,000 mg/kg bw/day dose groups. Hypoactivity and ataxia were resolved by the 4th week of the study. In addition, slight decreases in body weight gain and feed consumption were noted in the first two weeks of the 13-week study in the 1,000 mg/kg bw/day dose group. An inhalation, two-generation, reproductive toxicity study conducted with isobutyl alcohol (up to 2500 ppm) did not cause any parental systemic, reproductive, or neonatal toxicity when administered for two generations via whole-body exposure. In lifetime studies, rats given isobutyl alcohol by gavage or sc had increased incidences of total tumors including liver carcinomas, spleen sarcomas, proventricular carcinomas and myeloid leukemia, relative to controls. No adverse developmental effects were noted in rats or rabbits exposed by inhalation to 10,000 mg/cu m isobutyl alcohol during gestation. An increased rate of reverse mutation was demonstrated when Escherichia coli CA274 was treated with 0.7% isobutyl alcohol, without metabolic activation. In addition, isobutayl alcohol was negative in an in vivo mouse micronucleus study. ECOTOXICITY STUDIES: The lobster (Homarus americanus) was quickly and reproducibly anesthetized by the injection of isobutyl alcohol into the abdominal sinus. Isobutyl alcohol promoted cell elongation and increased total growth of wheat roots grown in white light; a higher concentration inhibited meristematic activity.

十二名受试者在休息和踏自行车测力计运动时,暴露于吸入空气中300或600毫克/立方米的丁醇。暴露持续2小时。动脉血中浓度较低。呼出气体最后一部分的浓度,即肺泡浓度,也较低。与低百分比吸收相比,肺泡浓度的比值也较低。丁醇中的高溶解性可能解释了这些结果。
Twelve subjects were exposed to 300 or 600 mg/cu m of butyl alcohol in inspired air during rest and during exercise on a bicycle ergometer. Exposure lasted 2 hr. The arterial blood concentration was low. The concentration in the last part of the expired air, ie, the alveolar concentration, was low. The quotient of alveolar concentration was low in relation to the low percentage uptake. The high solubility of butyl alcohol in water may explain the results.

大约618毫克/千克的异丁醇通过灌胃方式给予兔子。24小时后,剂量的4.4%以葡萄糖醛酸苷的形式在尿液中排出。对尿液或呼吸数据的分析表明,在给予兔子后40小时内,口服的异丁醇几乎不作为未改变的异丁醇排出。
About 618 mg/kg isobutanol was administered by gavage to rabbits. After 24 hours, 4.4% of the dose was excreted as a glucuronic acid conjugate in the urine. Analysis of urinary or breath data suggested that a negligible fraction of orally administered isobutanol was excreted as unchanged isobutanol within 40 hours after administration to rabbits.

Compounds 1b, 2c, 3b and 5b showed significant AhR antagonist activity in a transgenic zebrafish model. Among them, compound 3b, and 5b were found to have excellent AhR antagonist activity with IC50 of 3.36 nM and 8.3 nM in a luciferase reporter gene assay. In stem
    合成了一系列新的1,3-二酮,杂环和α,β-不饱和衍生物,并使用斑马鱼和哺乳动物细胞评估了它们的AhR拮抗剂活性。在转基因斑马鱼模型中,化合物1b,2c,3b和5b显示出显着的AhR拮抗剂活性。其中,在荧光素酶报告基因分析中,发现化合物3b和5b具有出色的AhR拮抗剂活性,IC 50为3.36 nM和8.3 nM。在干细胞增殖测定中,化合物5b引起明显的HSC扩增。
