  • 毒性总结
识别和使用:对羟基苯甲酸乙酯形成小的无色晶体或白色粉末。对羟基苯甲酸乙酯抑制真菌和细菌的生长,用作药品、粘合剂和各种化妆品的防腐剂。人体暴露和毒性:对羟基苯甲酸乙酯在人类中是皮肤刺激物。在一项人体研究中,它没有显示出致敏潜力。作为一类通用化合物,对羟基苯甲酸酯在应用到人体完整皮肤时很少引起致敏。应用到受损皮肤是更常见的致敏原因。已经证明,口服甲乙丙对羟基苯甲酸甲酯混合物会加剧预先存在的皮肤问题。动物研究:对羟基苯甲酸乙酯在兔眼中引起刺激。在实验动物中对羟基苯甲酸乙酯的急性口服毒性很低。有限的大鼠长期研究也表明其毒性很低,并未产生致癌活性的证据。对羟基苯甲酸乙酯在饮食中导致大鼠前胃细胞增殖。有限的埃姆斯细菌试验中没有报告突变性。对羟基苯甲酸乙酯在仓鼠卵巢细胞分析中增加了染色体畸变,但在用对羟基苯甲酸乙酯处理的大鼠中并未看到类似效果。在大鼠怀孕期间经口给予对羟基苯甲酸乙酯,在母体毒性剂量水平上发生了胎儿毒性。对羟基苯甲酸乙酯在大鼠中是非致畸形的。在一项体外研究中,对羟基苯甲酸乙酯的浓度低至8毫克/毫升时精子不可存活,但在小鼠饮食中含0.1%或1.0%对羟基苯甲酸乙酯的体内研究中报告没有精子毒性效应。
IDENTIFICATION AND USE: Ethylparaben forms small colorless crystals, or white powder. Ethylparaben inhibits the growth of fungi and bacteria and is used as a preservative for pharmaceuticals, adhesives, and various cosmetic preparations. HUMAN EXPOSURE AND TOXICITY: Ethylparaben was a skin irritant in man. It gave no evidence of sensitizing potential in a human study. The paraben esters as a generic class are rare sensitizers when applied to the intact skin of man. Application to the damaged skin is a more common cause of sensitization. A methyl:ethyl:propylparaben mixture has been shown on oral administration to exacerbate pre-existing skin complaints. ANIMAL STUDIES: Ethylparaben was an eye irritant in rabbits. A low acute oral toxicity has been demonstrated for ethylparaben in laboratory animals. Limited long-term studies in rats have also indicated a low toxicity and have generated no evidence of carcinogenic activity. Ethylparaben in the diet produced cell proliferation in the forestomach of rats. No evidence of mutagenicity was reported in limited Ames Bacterial tests. Ethylparaben did increase chromosomal aberrations in a Chinese Hamster ovary cell assay, but similar effects were not seen in rats treated with ethylparaben. Fetal toxicity at maternally toxic dose levels occurred in female rats treated orally during pregnancy. Ethylparaben was nonteratogenic in rats. In one in vitro study, sperm were not viabile at concentrations as low as 8 mg/mL for Ethylparaben, but an in vivo study of 0.1% or 1.0% for Ethylparaben in the diet of mice reported no spermatotoxic effects.

  • 相互作用
在同时给予水杨酸后,乙酯对苯甲酸生物命运与之前报告中单独给予乙酯对苯甲酸的情况不同。未结合的p-羟基苯甲酸的排泄增加,它是乙酯对苯甲酸的水解产物,而p-羟基苯甲酸苯甲酰甘氨酸结合物和p-羟基苯甲酸苯甲酰葡萄糖苷酸,它的酯型葡萄糖苷酸,的排泄减少。血液浓度模式与单独给予乙酯对苯甲酸的情况大不相同,尤其是每种代谢物的消除都延迟了。对血液浓度数据进行药代动力学分析的结果也显示水杨酸对乙酯对苯甲酸生物命运的影响。
The biological fates of ethyl paraben after the simultaneous administration with salicylic acid were different from those of ethyl paraben alone as reported in the previous reports. The excretion of unconjugated p-hydroxybenzoic acid, which is a hydrolyzed product of ethyl paraben, increased and those of p-hydroxyhippuric acid, glycine conjugate of p-hydroxybenzoic acid, and p-hydroxybenzoyl glucuronide, its ester type glucuronide, decreased. The blood concentration patterns were considerably different from those of ethyl paraben alone, especially the elimination of every metabolite was delayed. Pharmacokinetic analyses on the data of blood concentration were carried out and the results also show the interaction of salicylic acid on the biological fate of ethyl paraben.

甲基paraben、乙基paraben、丙基paraben和丁基paraben通过未经处理和去除脂质的豚鼠背部皮肤的渗透,以及3种渗透增强剂,N-十二烷基-2-吡咯烷酮(月桂基吡咯烷酮)、乙醇和薄荷醇(L-薄荷醇)与乙醇混合物对parabens渗透的影响进行了研究;研究了parabens的渗透性与辛醇(n-辛醇)/水分配系数之间的关系,以及渗透增强剂对含有角质层脂质的脂质体脂质双层流动性的影响。未经处理的豚鼠皮肤中parabens的渗透系数与其辛醇/水分配系数相关。在去除脂质的豚鼠皮肤中,parabens的渗透系数增加,与其辛醇/水分配系数无关。渗透增强剂对parabens渗透的影响是可变的。渗透增强剂增加了脂质体脂质双层的流动性。
The permeation of methylparaben, ethylparaben, propylparaben, and butylparaben through untreated and lipid-depleted excised guinea pig dorsal skin, and the effects of 3 penetration enhancers, N-dodecyl-2-pyrrolidone (lauryl pyrrolidone), ethyl alcohol (ethanol), and a mixture of menthol (l-menthol) and ethyl alcohol, on the permeation of the parabens were studied; the relationship between the permeability and octyl alcohol (n-octanol)/water partition coefficients of the parabens, and the effect of the penetration enhancers on the fluidity of the lipid bilayer of liposomes containing stratum corneum lipids were also examined. Permeability coefficients of the parabens correlated with their octyl alcohol/water partition coefficients in untreated guinea pig skin. In lipid-depleted guinea pig skin, permeability coefficients of the parabens increased and did not correlate with their octyl alcohol/water partition coefficients. The effect of the penetration enhancers on the permeation of the parabens was variable. The penetration enhancers increased the fluidity of liposome lipid bilayers.

在静脉注射乙基对羟基苯甲酸乙酯后,只有未水解的乙基对羟基苯甲酸乙酯在狗的大脑中发现。在肝脏、肾脏和肌肉中,它会立即被水解为对羟基苯甲酸。在狗口服1.0克/公斤乙基对羟基苯甲酸乙酯6小时后,自由和总乙基对羟基苯甲酸乙酯的血浆浓度达到峰值(分别为427和648微克/立方厘米)。48小时后,所有乙基对羟基苯甲酸乙酯被完全消除。
After ethyl paraben is intravenously infused into the dog, unhydrolyzed ethyl paraben is found only in the brain. In liver, kidney, and muscle, it is immediately hydrolyzed to p-hydroxybenzoic acid. Six hours after oral administration of 1.0 g/kg to dogs, the peak plasma concentration of free and total ethyl paraben (427 and 648 ug/cu cm, respectively) is reached. After 48 hr, all ethyl paraben is completely eliminated.

制备方法与用途

尼泊金乙酯为白色粉末,无特殊气味。其防腐效力强于苯甲酸和山梨酸。

用途

尼泊金乙酯是一种安全、高效且广谱的抗菌剂,主要用于医药工业、食品工业及纺织工业中的防腐处理。

作为一种水溶性防腐剂,尼泊金乙酯对霉菌和酵母菌具有较强的抑制作用,但对抗细菌特别是乳酸菌及革兰氏阴性杆菌的作用较差。其抗菌能力比山梨酸和苯甲酸更强,并且抗菌效果不受pH值的影响,在pH 4~8范围内均有效果。

使用限量
  • 食品中:尼泊金乙酯的使用量参照《食品添加剂使用卫生标准》(GB2760-1996)。具体用量为:
    • 果蔬保鲜:0.012g/kg
    • 食醋:0.10g/kg
    • 碳酸饮料、蛋黄馅:0.20g/kg
    • 果汁(味)饮料、果酱(不含罐头)、酱油、酱料:0.25g/kg
    • 糕点馅:0.5g/kg
含量分析

精确称取约2g预经80℃干燥2小时后的试样,加入40ml 1mol/L氢氧化钠溶液,煮沸30分钟。冷却后加5滴溴百里酚蓝指示剂,用1mol/L硫酸滴定过量的碱至终点颜色与pH6.5缓冲液中相同指示剂的颜色一致。空白试验同时进行。

毒性

尼泊金乙酯的ADI值为0~10mg/kg(FAO/WHO, 2001),急性口服毒性LD50为3g/kg(小鼠)。

安全特性
  • 急性口服毒性:小白鼠LD50=5000 mg/kg
  • 人体刺激性实验:在丙二醇中不引起刺激的浓度为7%
  • 使用浓度5%以下无任何刺激
化学性质

尼泊金乙酯为白色结晶或结晶性粉末,有特殊香味。易溶于乙醇、乙醚和丙酮,微溶于水、氯仿、二硫化碳和石油醚。

生产方法

将对羟基苯甲酸、乙醇、苯和浓硫酸依次加入酯化釜内(乙醇过量),搅拌加热进行酯化。蒸汽通过冷凝器冷凝后进入分水器以除去生成的水分,苯再回流入酯化釜内。当馏出液中不再含有水时,蒸除残余的乙醇和苯。

当反应釜内温度升至100℃后保持10分钟左右,无馏出液后趁热将反应液放入装有冷水并快速搅拌的清洗锅内,加入NaOH至中性溶解除去未反应的对羟基苯甲酸。离心过滤后的结晶用清水洗两次后移入脱色锅,在加热下用乙醇溶解,加活性炭脱色;趁热压滤后,滤液进入结晶槽结晶,过滤干燥即得尼泊金乙酯产品。

类别与性质
  • 类别:有毒物质
  • 毒性分级:中毒
  • 急性毒性:口服-小鼠 LD50: 3000 毫克/公斤
  • 可燃性危险特性:可燃,火场排出辛辣刺激烟雾
  • 储运特性:库房低温、通风、干燥
  • 灭火剂:水、二氧化碳、干粉、砂土

    A phosphine-catalyzed formal vinylogous aldol reaction of gamma-methyl allenoates with aldehydes is herein reported, in which the gamma-methyl group is directly involved in the carbon carbon bond formation. Under the catalysis of triarylphosphine (20 mol %) and in the presence of a protic additive, gamma-methyl allenoates and aldehydes chemo- and stereoselectively produce functionalized 1,3-dioxanes or dienols in modest to good yields. These chemical transformations provide easy excess to oxy-functionalized enoates and dienoates under very mild conditions. (C) 2013 Elsevier Ltd. All rights reserved.

    The present invention relates to acyl-hydrazone compounds, in particular 3,4,5-trimethoxyphenyl-hydrazide derivatives, as well as the oxadiazole analogs thereof and other similar compounds, and to the pharmaceutical use of the same for the treatment of various diseases associated with cell proliferation, such as leukemias, including acute lymphoblastic leukemia (ALL), tumours and inflammation. Acyl-hydrazones have been obtained having activity similar to that of the compound used as a standard in experiments (colchicine). The greater selectivity of the compounds according to the invention is an important feature, associated with fewer side effects than the pharmaceuticals used at present in clinical treatments. The synthetised acyl-hydrazones, more particularly the compounds 02 and 07, exhibited important antileukemic activity, which suggests 02 and 07 as candidates to pharmaceutical prototypes, or to pharmaceuticals for the treatment of leukemias, in particular acute lymphoblastic leukemia (ALL), tumours and other proliferative diseases, such as inflammation. The action mechanism of the most active compounds was determined by using DNA microarrays and subsequent tests indicated by the chip, besides selectivity studies in healthy human lymphocytes.
    本发明涉及酰基腙化合物,特别是3,4,5-三甲氧基苯基腙衍生物,以及其噁二唑类似物和其他类似化合物,以及它们在治疗与细胞增殖相关的各种疾病,如白血病(包括急性淋巴细胞白血病(ALL))、肿瘤和炎症方面的药用。已获得具有与实验中使用的化合物(秋水仙碱)相似活性的酰基腙。根据本发明的化合物具有更大的选择性,与目前在临床治疗中使用的药物相比,副作用更少是一个重要特征。合成的酰基腙,尤其是化合物02和07,表现出重要的抗白血病活性,这表明02和07可能成为药物原型的候选,或用于治疗白血病,特别是急性淋巴细胞白血病(ALL)、肿瘤和其他增殖性疾病,如炎症的药物。最活性化合物的作用机制是通过使用DNA微阵列确定的,并且通过芯片指示的后续测试,以及对健康人类淋巴细胞的选择性研究。
