代谢
正丁醇醋酸酯的代谢特点是母体化合物迅速解成正丁醇醋酸,这一过程由几种组织和血液中发现的酯酶催化。
The metabolism of n-butyl acetate is characterized by the rapid hydrolysis of the parent compound to n-butanol and acetic acid, a process which is catalyzed by esterases found in several tissues and blood.

代谢
使用放射性标记的正丁醇对雄性Sprague Dawley大鼠进行代谢研究,结果表明正丁醇非常迅速地从血液中消除(双相消除;半衰期= 0.41分钟),并且在给药后最初的2.5分钟内只在脑组织中以低浓度检测到(平均最大值为3.8微克当量/克,在1.9分钟时)。正丁醇在血液(Cmax = 52微克当量/克,在Tmax 2.6分钟时)和脑(Cmax = 79微克当量/克,在Tmax 2.5分钟时)中以更高浓度被发现,但这同样在两种组织中迅速消除(双相消除;半衰期为1.0 - 1.2分钟),并且在给药后20分钟内无法检测到。正丁酸在血液中以低浓度存在(平均最大值为5.7微克当量/克,在7.4分钟时)并在给药后缓慢下降;在脑组织中几乎未检测到。早期洗脱的极性代谢物,推测是(14)C正丁醇的克雷布斯循环中间体以及(14)C-正丁醇葡萄糖醛酸和硫酸结合物,在全血中检测到(平均最大值为12.2微克当量/克,在4.2分钟时),但在脑组织中仅以微量存在。在这个剂量平上,正丁醇在血液和脑中的解估计在2.7分钟内完成了99%。
Metabolism studies with male Sprague Dawley rats using radioactive labelled n-butyl acetate indicated that n-butyl acetate was very rapidly eliminated from the blood (biphasic elimination; half life = 0.41 min), and was detected in brain tissue only at low concentrations (mean maximum of 3.8 ug equivalents/g at 1.9 min) in the first 2.5 min following dosing. n-Butanol was found at higher concentrations in both blood (Cmax = 52 ug equivalents/g at Tmax 2.6 min)and brain (Cmax = 79 ug equivalents/g at Tmax 2.5 min), but this was also rapidly eliminated in both tissues (biphasic elimination; t1/2, of 1.0 - 1.2 min) and was undetectable beyond 20 min post dosing. n-Butyric acid was present at low concentrations in blood (mean maximum of 5.7 ug equivalents/g at 7.4 min) and declined slowly following dosing; it was largely undetected in brain tissue. Early eluting, polar metabolites, presumably Krebs cycle intermediates of (14)C n-butanol and glucuronide and sulfate conjugates of (14)C-n-butanol, were detected in the whole blood (mean maximum of 12.2 ug equivalents/g at 4.2 min), but were seen only in trace amounts in brain tissue. The hydrolysis of n-butyl acetate in blood and brain is estimated to be 99% complete by 2.7 min at this dose level.

代谢
代谢系列法风险评估使用基于计量学的分析来开发一组代谢相关化合物的毒性信息,使用每个化合物的药代动力学(PK)数据和母体化合物的毒性数据。以正丁基醋酸及其后续代谢物正丁醇和正丁酸(丁基系列)为例,首次使用暂定生理基础药代动力学(PBPK)模型演示了代谢系列法。这项工作的目标是完成丁基系列的PBPK模型开发。通过静脉注射、静脉输注或在一个循环闭合室中吸入的方式给予大鼠测试化合物。通过拟合这些实验中的血液时间过程数据来估计肝脏、血管和外血管的代谢常数。从闭合室吸入研究和测量的通气率估计了正丁基醋酸(100%肺泡通气)和正丁醇(50%肺泡通气)的呼吸道生物利用度。得到的丁基系列PBPK模型成功再现了这些化合物在大鼠静脉给药和吸入正丁基醋酸正丁醇暴露后的血液时间过程,以及人类吸入正丁醇暴露后的动脉血正丁醇动力学。这些经过验证的吸入途径模型可以用来支持对丁基系列化合物进行风险评估所需的物种和剂量-途径外推。使用模型推导出对应大鼠正丁基醋酸NOAELs 500和3000 ppm的人类等效浓度分别为169 ppm和1066 ppm的正丁醇
The metabolic series approach for risk assessment uses a dosimetry-based analysis to develop toxicity information for a group of metabolically linked compounds using pharmacokinetic (PK) data for each compound and toxicity data for the parent compound. The metabolic series approach for n-butyl acetate and its subsequent metabolites, n-butanol and n-butyric acid (the butyl series), was first demonstrated using a provisional physiologically based pharmacokinetic (PBPK) model for the butyl series. The objective of this work was to complete development of the PBPK model for the butyl series. Rats were administered test compounds by iv bolus dose, iv infusion, or by inhalation in a recirculating closed chamber. Hepatic, vascular, and extravascular metabolic constants for metabolism were estimated by fitting the model to the blood time course data from these experiments. The respiratory bioavailability of n-butyl acetate (100% of alveolar ventilation) and n-butanol (50% of alveolar ventilation) was estimated from closed chamber inhalation studies and measured ventilation rates. The resulting butyl series PBPK model successfully reproduces the blood time course of these compounds following iv administration and inhalation exposure to n-butyl acetate and n-butanol in rats and arterial blood n-butanol kinetics following inhalation exposure to n-butanol in humans. These validated inhalation route models can be used to support species and dose-route extrapolations required for risk assessment of butyl series family of compounds. Human equivalent concentrations of 169 ppm and 1066 ppm n-butanol corresponding to the rat n-butyl acetate NOAELs of 500 and 3000 ppm were derived using the models.

  • 毒性总结
识别和使用:乙酸正丁酯是一种无色液体。它用于制造漆、人造皮革、摄影胶片、塑料和安全玻璃。它也被用作有机溶剂和合成香料成分。人体研究:男性和女性志愿者暴露于不同浓度的乙酸正丁酯蒸气中,时间为2到5分钟。在200 ppm浓度下暴露3到5分钟,大多数受试者抱怨喉咙刺激;在300 ppm浓度下暴露3到5分钟,大多数报告眼睛和鼻子刺激以及严重的喉咙刺激。在严重过量的情况下,出现过虚弱、嗜睡和昏迷。人体长期暴露于乙酸正丁酯与轻微的皮肤刺激有关。皮肤反复接触液体可能导致脱脂和开裂。长期接触乙酸正丁酯的工人报告了结膜炎、胸部紧缩感和咳嗽。然而,只有当乙酸正丁酯与其他溶剂混合存在时,在职业环境中才会报告眼睛和呼吸道以及其他系统性损害的永久性病变,这些效果似乎是由其他溶剂引起的。动物研究:在最大值测试中使用豚鼠进行的测试表明,乙酸正丁酯没有致敏潜力。在五只白兔剃光的皮肤上涂抹0.01毫升纯材料24小时后,乙酸正丁酯略有刺激性。豚鼠在0.33%、0.7%或1.4%体积浓度的乙酸正丁酯蒸气中暴露1到810分钟后进行检查。在0.33%的浓度下,只有眼部刺激发生。在两个更高浓度下,注意到鼻部和眼部刺激、流泪、不协调、中枢神经系统抑制和呼吸障碍。只有在1.4%浓度下,在4小时后记录到死亡,且发生在暴露期间;轻微到中度的脑、肺和肾脏充血被注意到。在小白鼠中,活动降低效果的最小有效浓度为乙酯2000 ppm和乙酸正丁酯8000 ppm。检查了乙酸正丁酯在沙门氏菌(TA98、TA100、TA1535、TA1537和TA1538)和大肠杆菌(WP2uvrA)中的诱变性。在有无大鼠微粒体激活的条件下进行了突变试验。未观察到乙酸正丁酯的诱变活性。
IDENTIFICATION AND USE: n-Butyl acetate is a colorless liquid. It is used in manufacture of lacquer, artificial leather, photographic films, plastics, and safety glass. It is also used as an organic solvent and synthetic flavoring ingredient. HUMAN STUDIES: Male and female volunteers were exposed to different concentrations of n-butyl acetate vapor for 2 to 5 minutes. With exposure at 200 ppm for 3 to 5 minutes, the majority of the subjects complained of throat irritation; at 300 ppm for 3 to 5 minutes, the majority reported eye and nose irritation and severe throat irritation. In cases of severe overexposure, weakness, drowsiness, and unconsciousness have been seen. Chronic exposure to n-butyl acetate in humans has been associated with mild skin irritation. Repeated contact of the skin with the liquid may lead to defatting and cracking. Workers exposed chronically to n-butyl acetate have reported conjunctival irritation, feeling of chest constriction, and coughing. However, permanent lesions of the eyes and respiratory tract and other systemic effects have been reported in an occupational setting only when n-butyl acetate is present in a mixture with other solvents, and these effects appear to be due to the other solvents. ANIMAL STUDIES: n-Butyl acetate showed no sensitization potential when tested in a maximization test using guinea-pigs. Following 24 hr application of 0.01 mL of the neat material to the clipped skin of five albino rabbits, n-butyl acetate was slightly irritating. Guinea pigs exposed for 1 to 810 minutes at vapor concentration of 0.33, 0.7, or 1.4% by volume of n-butyl acetate were examined. At 0.33%, only eye irritation occurred. Irritation of the nose and eyes, lacrimation, incoordination, CNS depression, and respiratory disturbances were noted at the two higher concentration. Deaths were recorded only at the 1.4% concentration after 4 hours and occurred during exposure; slight to moderate congestion of the brain, lungs, and kidneys were noted. In mice, minimally effective concentrations for activity-decreasing effects were 2000 ppm for ethyl acetate and 8000 ppm for n-butyl acetate. The mutagenicity of n-butyl acetate in Salmonella typhimurium (TA98, TA100, TA1535, TA1537, and TA1538) and Escherichia coli (WP2uvrA) was examined. The mutation test was performed in the absence and presence of rat microsomal activation. No mutagenic activity was observed with n-butyl acetate.

    Novel processes for the preparation of adenosine compounds and intermediates thereto. The adenosine compounds prepared by the present processes may be useful as cardiovascular agents, more particularly as antihypertensive and anti-ischemic agents, as cardioprotective agents which ameliorate ischemic injury or myocardial infarct size consequent to myocardial ischemia, and as an antilipolytic agents which reduce plasma lipid levels, serum triglyceride levels, and plasma cholesterol levels. The present processes may offer improved yields, purity, ease of preparation and/or isolation of intermediates and final product, and more industrially useful reaction conditions and workability.

    The present invention is directed compositions for delivery of RNA interference (RNAi) triggers to integrin positive tumor cells in vivo. The compositions comprise RGD ligand- targeted amphipathic membrane active polyamines reversibly modified with enzyme cleavable dipeptide-amidobenzyl-carbonate masking agents. Modification masks membrane activity of the polymer while reversibility provides physiological responsiveness. The reversibly modified polyamines (dynamic polyconjugate or conjugate) are further covalently linked to an RNAi trigger.
    本发明涉及将RNA干扰(RNAi)触发物传递至体内整合素阳性肿瘤细胞的组合物。这些组合物包括以RGD配体为靶向的两性膜活性多胺,可逆地修饰为酶可切割二肽-酰胺基苄-碳酸酯掩蔽剂。修饰掩盖了聚合物的膜活性,而可逆性提供了生理响应性。这些可逆修饰的多胺(动态多共轭物或共轭物)进一步与RNAi触发物共价连接。
