代谢
当通过口服给药给哺乳期奶牛时,代谢物主要以葡萄糖苷酸结合物的形式出现在尿液中。建议发生双键的环氧化,随后环氧化物解成二元醇并与葡萄糖醛酸结合。
When given by oral admin to lactating cows, metabolites were present in urine mainly in form of glucuronide conjugates. It is suggested that epoxidation of double bonds occurred, followed by hydrolysis of epoxides to diols & conjugation with glucuronic acid.

代谢
... 二环戊二烯的尿代谢物没有特定地被识别,但是通过薄层色谱分析表明,小鼠和大鼠的尿液中各含有七个组分。在狗的尿液中发现了六个组分。这些组分的Rf值相似;因此,这三种生物体中都有共同的代谢物。在所有三种生物体中,只有1-3%的放射性归因于未代谢的(14)碳-二环戊二烯。当所有物种的尿液经过葡萄糖苷酶(β-葡萄糖苷酶和磺酸酶)的酶促解并提取后,在提取物中回收,表明尿液中存在结合物。
... Urinary metabolites of dicyclopentadiene were not identified specifically, but analysis by thin layer chromatography indicated that the urine of mice and rats each had seven components. Six components were found in the urine of dogs. The Rf values of these components were similar; therefore, common metabolites were indicated in all three species. Only 1-3% of the radioactivity was attributed to nonmetabolized (14)carbon-dicyclopentadiene in all three species. When the urine from all species was subjected to enzymatic hydrolysis by glusulase (beta glucuronidase and sulfatase) and extracted, was recovered in the extract, indicating the presence of urine conjugates.

毒理性
  • 毒性总结
识别和使用:环戊二烯(DCPD)是一种无色结晶固体(在90华氏度以上为液体)。DCPD用于制造环戊二烯作为杀虫剂中间体;在生产茂化合物;在油漆、清漆和树脂制造中;在生产弹性体、树脂系统和聚合物中。它还用作动物如野兔、兔子和鹿的驱避剂,在冬季或夏季。以浸渍条的形式应用于落叶树和针叶树上,或者通过喷洒在观赏植物和灌木周围。人类暴露和毒性:吸入后暴露迹象——咳嗽、喉咙痛和头痛;皮肤暴露——发红和疼痛;眼睛暴露——发红和疼痛;摄入——腹痛和恶心。研究了三名志愿者对DCPD的人类感官反应。据报道,气味阈值低至0.003 ppm。在两名受试者接触1和5.5 ppm 30分钟后,一名受试者在1 ppm下7分钟后出现轻度眼睛和喉咙刺激,另一名受试者在24分钟后报告嗅觉疲劳。在5.5 ppm下10分钟后报告眼睛刺激,但两名测试受试者均未报告嗅觉疲劳。工人的意外暴露,在前2个月内出现头痛,但在接下来的3个月内没有出现头痛,这表明一定程度的适应。动物研究:在兔子上对皮肤和眼睛有轻微刺激作用。四只大鼠中有三只在250 ppm下每天暴露6小时,连续10天存活,所有大鼠在100 ppm下连续15次暴露存活。在大鼠连续10天每天暴露于DCPD的情况下,大鼠在332 ppm平死亡,但在146和72 ppm平下没有死亡。所有死亡的大鼠都有抽搐和肺出血,肠内有血;雌性大鼠出现胸腺出血。小鼠在相同的暴露计划下,在146和72 ppm下死亡。在大鼠每天暴露7小时,连续89天暴露于74和35 ppm DCPD的情况下,观察到肾脏损伤。观察到一些肺部病变,如慢性肺炎和支气管扩张,但在检查的其他器官中没有看到剂量相关效应。在相同的暴露计划(89天暴露)下,在32、23和9 ppm DCPD下暴露的狗在所用的生化测试中只显示出最小的变化,在检查的28个器官中没有剂量相关变化。在雄性大鼠暴露于5和50 ppm DCPD时,在近曲小管上皮细胞中观察到透明滴状物,在第13周时,所有暴露于50 ppm DCPD的雄性大鼠都出现了管状蛋白尿。将小鼠通过吸入方式暴露于DCPD,每天7小时,每周5天,连续10天,剂量为47、72和146 ppm。所有小鼠在暴露的第一天表现出抽搐性死亡。在72 ppm下,五分之六的雄性和雌性小鼠在10天的暴露期间死亡,与在大鼠中观察到的抽搐或大体病变无关。在47 ppm下没有死亡发生,也没有观察到其他处理效应。在另一项研究中,四组各含45只雄性和45只雌性B6C3F1小鼠,通过吸入暴露于目标浓度为0、1.0、5.0或50 ppm的DCPD蒸气,每天6小时,每周5天,连续13周(64次暴露)。在最高暴露组中,有10只雄性和9只雌性小鼠在研究期间死亡,而其他任何一组中死亡的小鼠不超过2只。20只雌性怀孕大鼠在妊娠第6至15天口服给予DCPD,剂量为0、80、250、750 mg/kg/天。在第19天,母鼠被处死并检查;检查每个子宫的着床点、子宫角的位置、活胎和死胎的数量以及重吸收情况。对胎儿进行软组织变化和骨骼畸形的检查。母鼠没有观察到与化合物相关的肉眼病理效应或生殖性能的变化。胎儿没有内脏或骨骼畸形或性别比例的变化。在Salmonella测试中,DCPD在0、3、10、33、100和333 ug/板的剂量下对Salmonella typhimurium菌株(TA98、TA100、TA1535和TA1537)进行代谢激活或不激活,不具有诱变性。DCPD未诱导CHL/IU细胞的结构染色体畸变或多倍体;在体外微核试验中证实了阴性发现。
IDENTIFICATION AND USE: Dicyclopentadiene (DCPD) is a colorless crystalline solid (a liquid above 90 degrees F). DCPD is used in the manufacture of cyclopentadiene as a pesticide intermediate; in the production of ferrocene compounds; in paints, varnishes, and resin manufacture; in production of elastomers, resin systems, and polymers. It is also used as a repellent for animals such as hares, rabbits, and deer, in winter or in summer. Applied in the form of impregnated strip on deciduous and coniferous trees, or by spraying around ornamental plants and shrubs. HUMAN EXPOSURE AND TOXICITY: Signs of exposure after inhalation--cough, sore throat, and headache; skin exposure--redness and pain; eyes exposure--redness and pain; Ingestion--abdominal pain, and nausea. Human sensory responses to DCPD were studied in three human volunteers. The odor threshold was reported to be as low as 0.003 ppm. In two of the subjects exposed to 1 and 5.5 ppm for 30 minutes, one subject experienced mild eye and throat irritation after 7 minutes at 1 ppm, and the other subject reported olfactory fatigue after 24 minutes. Eye irritation was reported after 10 minutes, but no olfactory fatigue was reported by either test subject at 5.5 ppm. Accidental exposures of workers, in which headaches were experienced during first 2 months but were not experienced during next 3 months, indicate a certain degree of inurement. ANIMAL STUDIES: In rabbits it was slightly irritating to skin and eyes. Three of four rats survived ten 6-hour daily exposures at 250 ppm, and all survived 15 such exposures at 100 ppm. On daily, repeated exposures to DCPD for 10 days, rats succumbed at the 332 ppm level, but not at the 146 and 72 ppm levels. All dying rats succumbed with convulsions and hemorrhage of the lungs with blood in the intestines; with the females, hemorrhage of the thymus. Mice exposed under the same schedule died at both 146 and 72 ppm. After exposures of 7 hours/day for 89 exposure days, kidney damage was seen in rats exposed at 74 and 35 ppm DCPD. Some lung involvement was seen as chronic pneumonia and bronchiectasis, but no dose related effect was seen in other organs examined. Dogs exposed under the same schedule (89 exposure days) at 32, 23, and 9 ppm DCPD showed only minimal changes in the biochemical tests used, and no changes that were dose-related in 28 organs examined. Hyaline droplets in the proximal convoluted tubular epithelial cells of the kidney were seen in male rats exposed to 5 and 50ppm DCPD and tubular proteinosis was seen by week 13 in all male rats exposed to 50ppm DCPD. Mice were exposed to DCPD by inhalation for 7 hours per day, 5 days per week for 10 days at 47, 72, and 146 ppm. All mice exhibited convulsive deaths on the first day of exposure. Death at 72 ppm occurred in five of six mice of each sex during the 10 days of exposure and was not associated with the convulsions or gross lesions observed in rats. No deaths occurred at 47 ppm and no other effects of treatment were observed. In other study four groups, each consisting of 45 male and 45 female B6C3F1 mice, were exposed to DCPD vapor by inhalation 6 hr/day, 5 days/week, for 13 weeks (64 exposures) at targeted concentrations of 0, 1.0, 5.0, or 50 ppm. Ten male and nine female mice in the highest exposure group died during the study, while no more than two mice died in any other group. 20 female pregnant rats were admin DCPD orally at 0, 80, 250, 750 mg/kg/day for days 6 to 15 gestation. On day 19, the dams were sacrificed and examined; each uterus was examined for implantation sites, placement in uterine horns, number of live and dead fetuses and resorptions. Fetuses were examined for soft tissue changes and skeletal abnormalities. No compound-related gross pathological effects or changes in reproductive performance were seen in the dams. There were no visceral or skeletal malformations or changes in sex ratio in the fetuses. DCPD was not mutagenic in the Salmonella assay at doses of 0, 3, 10, 33, 100, and 333 ug/plate in Salmonella typhimurium strains (TA98, TA100, TA1535, and TA1537) with or without metabolic activation. DCPD did not induce structural chromosomal aberration or polyploidy in CHL/IU cells; negative finding were confirmed in the in vitro micronucleus test.

通常情况下,尽管有些二环戊二烯可以未经改变地呼出,但大部分被吸收的二环戊二烯会在肝脏发生羟基化,进行葡萄糖醛酸苷结合,并通过尿液排出体外。

四甲撑亚酰衍生物的诺波烷(TPNB)和二环戊二烯(TPDCPD)被显示能够轻易与(99m)Tc形成稳定的螯合物,这些螯合物在骨骼中有高且选择性的摄取。在 rats 和 rabbits 中,(99m)Tc-TPNB的骨骼摄取和血液清除特性与(99m)Tc-MDP相似。这表明,需要进一步研究以评估(99m)Tc-TPNB 或其他基于大有机多元螯合磷酸配体作为潜在的骨显像剂。
Tetramethylenephosphonate derivatives of norborane (TPNB) and dicyclopentadiene (TPDCPD) were shown to readily form stable chelates with (99m)Tc that had high and selective bone uptake. The skeletal uptake and blood clearance properties of (99m)Tc-TPNB were similar to (99m)Tc-MDP in both rats and rabbits. This suggests additional studies to further evaluate (99m)Tc-TPNB or perhaps other large-organic based multidentate phosphonate ligands as potential bone imaging agents is warranted.

制备方法与用途

环戊二烯 (Dicyclopentadiene, DCPC)

环戊二烯(Dicyclopentadiene,简称DCPC)是环戊二烯的二聚物。生产过程通常包括以下步骤:首先加热环戊二烯使其共聚成双环戊二烯,并从沸点小于45℃的轻组分中通过蒸馏分离出双环戊二烯;接着利用溶剂萃取出其他需要的双烯、单烯及饱和烃成分。高纯度的双环戊二烯在室温下为无色结晶体,而含有杂质时则呈现浅黄色油状液体,并带有刺激性的樟脑味。这种化合物不溶于,但可溶于醇和醚等有机溶剂。

应用

由于DCPD可以在特定温度下转化为CPD(环戊二烯),极大地拓宽了其应用范围。它不仅在医药、农药、香料等领域有着广泛用途,还可以作为生产不饱和树脂属茂、金刚烷戊二醛、双环戊二烯化物等原料,并用于合成橡胶、高能燃料等多个领域。
