毒理性
  • 毒性总结
识别和使用:2-羟基乙基丙烯酸酯(HEA)是一种液体。HEA主要用于作为聚合物的共聚单体或在制造化学中间体时的化学反应物。在聚合物制造中,HEA可以与丙烯酸丙烯酸酯、甲基丙烯酸酯、醋酸乙烯酯、氯乙烯、偏二氯乙烯苯乙烯丁二烯等进行共聚。与HEA反应的共反应物包括芳香族和脂肪族异氰酸酯、酐和环氧树脂。使用HEA制造的聚合物和化学中间体在汽车顶层涂料、建筑涂料、光固化树脂和粘合剂等领域有应用。HEA的衍生物曾作为实验性治疗进行测试。人体研究:在暴露浓度为3 ppm(名义值)及以上时,观察到眼睛和鼻子的刺激。刺激的严重程度随浓度增加而加剧,在10 ppm时可以忍受几分钟。对(甲基)丙烯酸酯进行15年贴片测试的经验总结显示,在440名有(甲基)丙烯酸酯暴露史的病人中,最常见的阳性测试反应是2-羟基乙基丙烯酸酯(9.6%)。动物研究:未稀释的HEA对皮肤有严重刺激作用。几项研究表明,未稀释的HEA对眼睛有严重刺激作用并可能造成损害。大鼠对HEA的吸入数据显示,7小时暴露于264 ppm(1250 mg/m³)没有致死效应。吸入暴露于333至394 ppm,分别为4或8小时,引起了刺激并处于致死阈值区域。在500 ppm及以上暴露时,接近100%的致死率被观察到。评估HEA急性皮肤毒性的关键研究使用了家兔,并应用了未稀释的测试材料。在塑料封闭绷带下,对家兔施以63、130、160、200或250 mg/kg体重的局部剂量,持续24小时。所有处理的动物都出现了明显的皮肤红斑和肿,一些动物观察到轻微到中度的皮肤坏死。毒性临床体征包括嗜睡、活动减少、食欲减退,在250 mg/kg体重时,只有快速浅表呼吸。评估HEA急性口服毒性的关键研究是通过灌胃给四组大鼠分别施以266.7、400、600和900 mg/kg体重的10%溶液。动物在给药后观察了14天。各剂量平下的死亡率为0/4、0/4、3/4和4/4。临床体征包括活动减少、粗糙毛发、呼吸困难、肌肉无力、死亡的动物出现胃肠道出血。纯净物质可能会烧伤口腔、喉咙和胃肠道的组织。在小鼠局部淋巴结试验中报告了阳性反应,表明HEA具有皮肤致敏性。在大鼠的慢性吸入研究中,5或0.5 ppm的处理组没有显示出显著慢性毒性或致癌效应的迹象(雄性和雌性大鼠每天暴露于HEA 6小时,每周5天,持续18个月)。HEA没有改变狗或大鼠的睾丸或子宫的组织病理学(狗饮食中最高达0.4%,大鼠最高达150 mg/kg体重/天)。在大鼠发育研究中,没有观察到与治疗相关的植入数量增加、胚胎/胎儿死亡率或胎儿畸形。在大鼠测试中,HEA的神经毒性潜力似乎最小。HEA在有无代谢活化的情况下对沙门氏菌属伤寒杆菌均不具有诱变性。生态毒性研究:使用瓦堡试验,HEA被认为对适应的污泥不具有毒性。
IDENTIFICATION AND USE: 2-Hydroxyethyl acrylate (HEA) is a liquid. HEA is used mainly either as a co-monomer in the manufacture of polymers or as a chemical reactant in the manufacture of chemical intermediates. In the manufacture of polymers, HEA can be co-polymerized with acrylic acid, acrylates, methacrylates, vinyl acetate, vinyl chloride, vinylidene chloride, styrene, butadiene, and the like. Co-reactants with HEA include aromatic and aliphatic isocyanates, anhydrides, and epoxides. The polymers and chemical intermediates made with HEA find applications in automotive top coatings, architectural coatings, photocure resins, and adhesives. Derivatives of HEA had been tested as experimental therapy. HUMAN STUDIES: Irritation of eyes and nose was observed at exposure concentrations of 3 ppm (nominal) and higher. The severity of irritation increased with concentration and could be tolerated for several minutes at 10 ppm. A summary of 15 years of experience of patch testing to (meth)acrylates presented the results in 440 patients with a history of exposures to (meth)acrylates. The most frequent positive test reactions were seen with 2-hydroxyethyl acrylate (9.6%). ANIMAL STUDIES: Undiluted HEA is severely irritating to the skin. Several studies have shown that undiluted HEA is severely irritating and can damage the eye. Inhalation data available for rats on HEA indicate that a 7 hour exposure of 264 ppm (1250 mg/cu m) had no lethal effect. Inhalation exposures to 333 to 394 ppm for 4 or 8 hours respectively caused irritation and were in the threshold area for lethality. At exposures at 500 ppm and above, close to 100% lethality was observed. The key study evaluating the acute dermal toxicity of HEA used rabbits and applied undiluted test material. Topical doses of 63, 130, 160, 200 or, 250 mg/kg bw were applied for 24 hours under a plastic occlusive bandage. Marked erythema and edema of the skin was seen in all treated animals and slight to moderate necrosis of the skin was observed in some animals. Clinical signs of toxicity were lethargy, decreased activity, loss of appetite and at 250 mg/kg bw only, rapid shallow breathing. The key study evaluating the acute oral toxicity of HEA administered as a 10% solution by gavage to groups of four rats at doses of 266.7, 400, 600, and 900 mg/kg bw. The animals were observed for 14 days post-dosing. The mortality was 0/4, 0/4, 3/4, and 4/4 at each dose level, respectively. Clinical signs included hypoactivity, rough fur, labored breathing, muscle weakness, GI tract hemorrhage in the animals that died. Neat material may burn the tissues of the mouth, throat and gastrointestinal tract. Positive responses have been reported in mice in the local lymph node assay indicating HEA dermal sensitization. There was no indication of significant chronic toxicity or a carcinogenic effect in either the 5 or 0.5 ppm treatment groups in rats in a chronic inhalation study (male and female were exposed to HEA 6 hours per day, 5 days/week for 18 months). HEA did not alter the histopathology of the testes or uterus in either dogs or rats (dogs up to 0.4% in the diet, rats up to 150 mg/kg bw/day). There were no treatment-related increases in the number of implants, embryo/fetal mortality, or fetal malformations observed in developmental study in rats. Neurotoxic potential of HEA appears to be minimal when tested in rats. HEA was not mutagenic in Salmonella typhimurium with or without metabolic activation. ECOTOXICITY STUDIES: Using the Warburg test, HEA was judged non-toxic to adapted sewage sludge.

吸收、分配和排泄
2-羟基乙基丙烯酸酯(HEA)在一项研究中进行了评估,该研究检查了雄性Fischer 344大鼠通过口服、腹腔注射、皮肤和吸入途径暴露下的代谢和排泄情况... 对于口服和腹腔注射暴露途径,大鼠(每种剂量平/暴露途径四只动物)单次接受了2.5或50毫克/千克体重的(14)C-HEA剂量。对于吸入暴露,六只大鼠在仅有头部的吸入室中暴露于目标浓度为8 ppm的(14)C-HEA,持续六小时。对于皮肤暴露,四只大鼠以50毫克/千克的剂量接受了(14)C-HEA处理。观察到的尿液代谢物在途径之间没有定性差异,表明HEA的代谢命运没有明显的途径依赖性差异。研究结果表明,一旦化学物质在体内系统性地可用,它就会被迅速代谢,并以呼出空气中的CO2或尿液代谢物的形式从体内排出,每条途径大约有相等百分比的管理/暴露剂量被消除。放射性消除的半衰期大约为尿液14小时和 17小时。尽管标签与母体HEA无关,但血浆中放射性消除的半衰期大约为26小时。HEA的代谢数据与其他丙烯酸酯的研究信息一致,其中酯功能的解是主要的代谢途径。类比乙基丙烯酸酯和丙烯酸,预计HEA的一个次要代谢途径将与谷胱甘肽结合,产生的巯基酸衍生物通过尿液排出。
2-hydroxyethyl acrylate (HEA) has been evaluated in a study that examined metabolism and excretion in male Fischer 344 rat using oral, intraperitoneal, dermal and inhalation routes of exposure ... For the oral and intraperitoneal routes of exposure the rats (four animals/dose level/route of exposure) received a single dose of (14)C-HEA at 2.5 or 50 mg/kg bw. For the inhalation exposure, six rats were exposed to a target concentration of 8 ppm (14)C-HEA for six hours in a head only inhalation chamber. For the dermal exposure, four rats were treated with (14)C-HEA at a dose of 50 mg/kg. No qualitative differences in urinary metabolites between routes were observed, indicating no marked route-dependent differences in the metabolic fate of HEA. The results of the study indicate that once the chemical becomes systemically available it is rapidly metabolized and eliminated from the body as either CO2 in the expired air or urinary metabolites with approximately equal percentage of administered/exposed dose eliminated by each route. The half-lives of elimination of radioactivity were approximately 14 hours for urine and 17 hours for CO2. The halflife of elimination of radioactivity from plasma was approximately 26 hours although the label was not associated with parent HEA. The available metabolic data on HEA is consistent with information on studies with other acrylates where hydrolysis of the ester functionality is the primary metabolic pathway. By analogy with ethyl acrylate and acrylic acid, it is expected that a minor metabolic pathway for HEA will be via conjugation with glutathione with the resulting mercapturic acid derivatives being excreted in the urine.

吸收、分配和排泄
HEA的代谢和排泄已经在雄性Fischer 344大鼠中进行了研究,使用了口服、腹腔注射、皮肤和吸入等暴露途径... 对于口服和腹腔注射暴露途径,大鼠(每剂量平/暴露途径4只动物)接受了单次剂量为2.5或50 mg/kg体重的HEA(大约15-20微居里)。对于吸入暴露,六只大鼠在一个仅头部吸入的实验舱中以8 ppm的目标浓度暴露于(14)C HEA,持续6小时。对于皮肤暴露,4只大鼠以12.5 mg/kg体重的剂量接受了(14)C HEA的处理。不同暴露途径之间在尿液代谢物上没有观察到定性差异,表明HEA的代谢命运没有明显的途径依赖性差异。研究结果表明,一旦化学物质在体内系统性地可用,它就会被迅速代谢并从体内排出,作为呼出空气中的CO2或尿液代谢物。关于HEA的代谢数据与具有其他丙烯酸酯类物质的物质的信息一致,其中酯功能的解是主要的代谢途径。类似于乙基丙烯酸丙烯酸,预计HEA的一个次要代谢途径是通过与谷胱甘肽结合,形成的巯基酸衍生物通过尿液排出。对于口服和腹腔注射途径(2.5 mg/kg体重),在给药后48小时内,35-36%的给药剂量以(14) 的形式呼出,43-47%的剂量通过尿液排出。在50 mg/kg体重时,40-45%的剂量以(14) 的形式呼出,33-36%的剂量通过尿液排出。经皮肤给药后,在给药后48小时内吸收了66%的剂量,剩余的33%与给药部位相关。吸收的剂量中有27%以HEA的代谢物形式通过尿液排出,27%以(14) 的形式通过呼出空气排出。对于吸入途径,48小时内通过尿液排出了吸收剂量的39%,41%以(14) 的形式呼出。对于所有途径,9-16%的剂量在组织和尸体中被发现,而在粪便中不到3%。
The metabolism and excretion of HEA has been examined in male Fischer 344 rat using oral, intraperitoneal, dermal and inhalation routes of exposure ... For the oral and intraperitoneal routes of exposure the rats (4 animals/dose level/route of exposure) received a single dose of 2.5 or 50 mg/kg bw (approx 15-20 uCi). For the inhalation exposure six rats were exposed to a target concentration of 8 ppm (14)C HEA for 6 hours in a head only inhalation chamber. For the dermal exposure 4 rats were treated with (14)C HEA at a dose of 12.5 mg/kg bw. No qualitative differences in urinary metabolites between routes were observed, indicating no marked route-dependent differences in the metabolic fate of HEA. The results of the study indicate that once the chemical becomes systemically available it is rapidly metabolized and eliminated from the body as either CO2 in the expired air or urinary metabolites.

By analogy with ethyl acrylate and acrylic acid it is expected that a minor metabolic pathway for HEA will be via conjugation with glutathione with the resulting mercapturic acid derivatives being excreted in the urine. For the oral and intraperitoneal routes (2.5 mg/kg bw) 35-36% of the administered dose was expired as (14)CO2 and 43-47% of the dose excreted via the urine by 48 hours post-dosing. At 50 mg/kg bw 40-45% of the dose was expired as (14)CO2 and 33-36% of the dose was excreted in the urine. Following dermal administration 66% of the dose was absorbed within 48 hours of the application with remaining 33% being associated with the application site. Of the absorbed dose 27% was excreted in the urine as metabolites of HEA and 27% was excreted in the expired air as (14)CO2. For inhalation 39% of the absorbed dose was eliminated in the urine by 48 hr and 41% was expired as (14)CO2. For all routes, 9-16% was found in the tissues and carcass and less than 3% in the feces.

吸收、分配和排泄
在给Fisher 344雄性大鼠口服给药(14)C-HEA后,给药的放射活性的91%至95%在尿液中、二氧化碳、粪便、组织、尸体、挥发性有机物和最终笼子清洗中被回收。在2.5 mg (14)C-HEA/kg体重这种低剂量下,口服给药途径大约有43-47%的剂量通过尿液排出,这是主要的消除途径,而有35-36%的剂量以(14)CO2的形式呼出,组织和尸体占剂量的9-13%。给药的放射活性中不到1.5%在粪便中被回收,不到1%在最终的笼子清洗中被发现。剂量中不到0.2%以挥发性有机物的形式在呼出的空气中回收。 在50 mg/kg (14)C-HEA/kg体重这种较高剂量下,口服给药途径有33-36%的剂量通过尿液排出,而有40-45%的剂量以(14) 的形式呼出。在这个较高剂量下,主要的消除途径从尿液途径转变为以呼出(14) 作为主要的消除途径。与2.5 mg/kg剂量一样,组织和尸体占剂量的10-13%,回收的放射活性中不到0.6%在最终的笼子清洗中,不到0.1%以挥发性有机物的形式在呼出的空气中回收,不到2.5%的剂量在粪便中被回收。 口服给药后,剂量的0.3-1.5%在给药后15分钟内就以(14) 的形式呼出。 排泄的峰值发生在4-8小时收集间隔期间或之前。在口服给药2.5 mg/kg后12小时,剂量的31-32%以(14) 的形式呼出。在50 mg/kg口服给药后相同的收集间隔期间,剂量的41%以(14) 的形式呼出。(14)C-HEA来源的(14) 呼出似乎遵循一级动力学作为双相过程,除了经皮给药后。口服给药后,通过尿液排出的总放射活性的92%以上在前12小时收集间隔期间被排出。
Following oral administration of (14)C-HEA to Fisher 344 male rats, between 91 and 95% of the administered radioactivity was recovered in the urine, CO2, feces, tissues and carcass, volatile organics and final cage wash. At the low dose of 2.5 mg (14)C-HEA/kg body weight, for the oral route of administration, approximately 43-47 % of the dose was eliminated in the urine, the primary elimination route, whereas 35-36% of the dose was expired as (14)CO2, and the tissues and carcass accounted for between 9-13 % of the dose. Less than 1.5% of the administered dose of radioactivity was recovered in the feces and less than 1% was found in the final cage wash. Less than 0.2% of the dose was recovered as volatile organics in the expired air. At the higher dose of 50 mg/kg (14)C-HEA/kg body weight, for the oral route of administration, 33-36% of the dose was eliminated in the urine, whereas 40-45% of the dose was expired as (14)CO2. At this higher dose there was a shift from the urinary pathway as the primary route of elimination to the exhalation of (14)CO2 as the primary route of elimination. As with the 2.5 mg/kg dose, the tissues and carcass accounted for 10-13% of the dose and less than 0.6% of the recovered radioactivity was in the final cage wash, less than 0.1% was recovered as volatile organics in the expired air and less than 2.5% of the dose was recovered in the feces. Following the oral route of administration, 0.3-1.5% of the dose was expired as (14)CO2 as early as 15 minutes post-dosing. The peak of CO2 excretion occurred during or before the 4-8 hr collection interval. By 12 hr post-dosing with 2.5 mg/kg for the oral route of administration, 31-32 of the dose was expired as (14)CO2. For this same collection interval following 50 mg/kg oral administration, 41 of the dose was expired as (14)CO2. The exhalation of (14)CO2 derived from (14)C-HEA appeared to follow first-order kinetics as a biphasic process, except following dermal administration. Following oral administration, greater than 92% of the total radioactivity excreted via the urine was excreted during the first 12 hr collection interval.

    Synthesis of Well-Defined Y-Shaped Zwitterionic Block Copolymers via Atom-Transfer Radical Polymerization
    摘要:
    A series of well-defined Y-shaped (AB(2)-type) zwitterionic block copolymers were synthesized by atom-transfer radical polymerization (ATRP). First, a bishydroxy-functional ATRP initiator was synthesized by esterification of 2-hydroxyethyl acrylate with 2-bromoisobutyryl bromide, followed by Michael addition using excess diethanolamine. 2-(Diethylamino)ethyl methacrylate (DEA) was polymerized via ATRP using this bishydroxy-functional initiator. The bromine end groups of PDEA were then quantitatively removed by radical chain transfer using excess N,N,N',N",N"-pentamethyldiethylenetri-amine (PMDETA). Esterification of the omega-bishydroxyl end groups using excess 2-bromoisobutyryl bromide afforded a PDEA-based omega-bifunctional macroinitiator [PDEA-(Br)(2)]. A series of Y-shaped zwitterionic PDEA-(PSEMA)(2) [PSEMA poly(succinyloxyethyl methacrylate)] block copolymers were synthesized via ATRP of 2-hydroxyethyl methacrylate (HEMA) using this PDEA-(Br)(2) macroinitiator, followed by reacting the HEMA hydroxyl groups with succinic anhydride. The 'schizophrenic' micellization character of these Y-shaped zwitterionic block copolymers in aqueous solution was confirmed by H-1 NMR spectroscopy, aqueous electrophoresis, and dynamic light-scattering studies.

    To search for new antiestrogens more effective in treating breast cancers, we explored alternatives to the acrylic acid side chain used in many antiestrogens. To facilitate our search, we used a simple adamantyl ligand core that by avoiding stereochemical issues enabled rapid synthesis of acrylate ketone, ester, and amide analogs. All compounds were high affinity estrogen receptor α (ERα) ligands but
    为了寻找在乳腺癌中更有效的新型抗雌激素,我们探索了许多抗雌激素丙烯酸侧链的替代物。为了方便我们的搜索,我们使用了一个简单的金刚烷配体核心,该核心通过避免立体化学问题而实现了丙烯酸酯,酯和酰胺类似物的快速合成。所有化合物均为高亲和力雌激素受体α(ERα)配体,但作为抗增殖剂和ERα下调剂表现出一系列功效和功效。具有微小结构变化的化合物之间的活性差异很大,但抗增殖和ERα下调的功效通常相互平行。一些具有侧链极性基团的化合物具有特别高的亲和力。次生羧酰胺具有最佳的细胞活性,3-羟丙基酰胺在抑制细胞增殖和基因表达方面与氟维司群一样有效。这项研究基于简单的金刚烷基核心结构以及针对细胞拮抗剂活性进行了优化的丙烯酸酯侧链,生产出了结构新颖的抗雌激素药。

    ArNMeCH(SiMe3)2 has been developed as a useful precursor of a formal α-aminoalkyl diradical in Ru(bpy)3Cl2-catalzyed addition with alkenes under visible-light-mediated photoredox conditions. This approach leads to homo-diaddition with two identical alkenes in one-pot, or hetero-diaddition with two different alkenes via a sequential operation.
