(14)C-1,4-cyclohexanedimethanol (CHDM) (70% trans-, 30% cis-isomers) was dissolved in water & given to male & female charles river cd (SD) rats by gavage in doses of 40 or 400 mg/kg of body wt. Metabolites were identified in plasma & urine by gas chromatography & gas chromatography-mass spectrometry. In addn to CHDM, 4-hydroxymethylcyclohexanecarboxylic acid was detected in plasma. Unchanged chdm was not detected in urine. The major metabolites identified in urine were cyclohexanedicarboxylic acid (68%) & 4-hydroxymethylcyclohexanecarboxylic acid (31%). Less than 2% of radioactivity in urine was not fully characterized. The cis-trans ratio of metabolites excreted in urine was the same as that of original dose.
/SRP:/ Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Poisons A and B/
/SRP:/ Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if needed. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary ... . Monitor for shock and treat if necessary ... . Anticipate seizures and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with 0.9% saline (NS) during transport ... . Do not use emetics. For ingestion, rinse mouth and administer 5 mL/kg up to 200 mL of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool ... . Cover skin burns with dry sterile dressings after decontamination ... . /Poisons A and B/
/SRP:/ Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious, has severe pulmonary edema, or is in severe respiratory distress. Positive-pressure ventilation techniques with a bag valve mask device may be beneficial. Consider drug therapy for pulmonary edema ... . Consider administering a beta agonist such as albuterol for severe bronchospasm ... . Monitor cardiac rhythm and treat arrhythmias as necessary ... . Start IV administration of D5W /SRP: "To keep open", minimal flow rate/. Use 0.9% saline (NS) or lactated Ringer's if signs of hypovolemia are present. For hypotension with signs of hypovolemia, administer fluid cautiously. Watch for signs of fluid overload ... . Treat seizures with diazepam or lorazepam ... . Use proparacaine hydrochloride to assist eye irrigation ... . /Poisons A and B/
/LABORATORY ANIMALS: Acute Exposure/ Rats (10 used, not specified if per dose or total) were administered 1,4-cyclohexanedimethanol via oral gavage at doses of 400 - 6400 mg/kg-bw and were observed for 14 days. Animals appeared normal to very weak with prostration and vasodilatation.
/LABORATORY ANIMALS: Subchronic or Prechronic Exposure/ Male (12/dose) and female (10/dose) Sprague-Dawley rats administered 1,4-cyclohexanedimethanol in their drinking water at concentrations of 0, 4.0, 8.0 or 12.5 mg/L for 13 weeks. The approximate dose levels achieved were 0, 256, 479 or 861 mg/kg-bw/day in males and 0, 440, 754 or 1754 mg/kg-bw/day in females. High-dose rats experienced decreased survival and had bloody or brown/red discolored urine, softened and/or reduced feces, reductions in body weights and weight gains, decreased feed consumption and increased urinary protein levels. No treatment-related effects were seen in animals receiving the mid- and low-dose levels. LOAEL (male) = 861 mg/kg-bw/day (based on decreased survival, abnormal urine and feces, reduced body weights and weight gains, decreased feed consumption and increased urinary protein levels) LOAEL (female) = 1754 mg/kg-bw/(based on decreased survival, abnormal urine and feces, reduced body weights and weight gains, decreased feed consumption and increased urinary protein levels) NOAEL (male) = 479 mg/kg-bw/day NOAEL (female) = 754 mg/kg-bw/day
(14)C-1,4-cyclohexanedimethanol (CHDM) (70% trans-, 30% cis-isomers) was dissolved in water & given to male & female charles river cd (SD) rats by gavage in doses of 40 or 400 mg/kg of body wt. (14)C-CHDM was rapidly absorbed from GI tract. After 48 hr, 95% of dose was excreted in urine, 2.5% in feces, & 0.03% respired as (14)CO2 & 0.4% remained in carcass. The recovery of radioactivity averaged 98.9% of dose. T/2 of CHDM in plasma from rats dosed with 400 mg/kg was about 13 minutes.
聚的新的共聚酯(丁烯共-1,4-环己烷二亚甲基-2,5-呋喃二甲酸)(PBCFs)从2,5-呋喃二甲酸(FDCA),1,4-丁二醇合成的(BDO)和1 ,4-环己烷二甲醇(CHDM)通过两步酯化-缩聚程序进行。合成聚合物的结构特征为11 H NMR和表征结果表明该共聚物在随机顺序结构中具有三单元组组分。可以通过改变BDO与CHDM的进料摩尔比来调节共聚物中的平均序列长度和单体百分比,但是,在缩聚过程中容易除去BDO有利于形成包含CHDM单元的长链连接。共聚酯组成可以由定量13 C NMR光谱计算得出,该光谱与元素分析结果非常吻合。CHDM单元并入聚(2,5-呋喃二甲酸丁二酯)(PBF)中可以显着影响PBCF的热转变行为,热稳定性和结晶度。PBCF显示T g随CHDM含量单调增加,DSC法表征的T g与Fox方程计算值一致。随着共聚物中CHDM单元的摩尔百分比从20%增加到70%,T g从45

We have previously identified the 7,8,9,10-tetrahydro-7,10-ethano-1,2,4-triazolo[3,4-a]phthalazine (1) as a potent partial agonist for the alpha(3) receptor subtype with 5-fold selectivity in binding affinity over alpha(1). This paper describes a detailed investigation of the substituents on this core structure at both the 3- and 6-positions. Despite evaluating a wide range of groups, the maximum selectivity
