代谢
在代谢研究中,以下代谢物在大鼠尿液中被发现,这些大鼠已经喂食了8000 ppm的丙泊13周:M1 = 1,2-二羟基苯(=儿茶酚);M2 = 2-异丙氧基;M3 = 2-羟基苯甲基碳酰胺;M4 = 2-异丙氧基苯基碳酰胺酸;M5 = 异丙氧基苯基-羟基甲基碳酰胺;M6 = 2-异丙氧基-5-羟基苯基甲基碳酰胺;M7 = 2-异丙氧基-5-羟基苯基碳酰胺酸;M8 = 2-异丙氧基-5-羟基苯基羟甲基碳酰胺;M9 = 1,5-二羟基-2-异丙氧基苯。在附加研究中,M6(= 2-异丙氧基-5-羟基苯基甲基碳酰胺)被确认为仓鼠、小鼠和人类的主要代谢物。硝化化合物M9A(= 1-羟基-2-异丙氧基-4-硝基苯)已在大鼠、小鼠、猕猴和人类中被确认为代谢物。来自人类研究的证据表明M9A是在胃中合成的。
In a metabolism study, the following metabolites were identified in the urine of rats which had been fed 8000 ppm propoxur for 13 weeks: M1 = 1,2-dihydoxybenzene (= catechol); M2 = 2-isopropoxyphenol; M3 = 2-hydroxyphenyl methylcarbamate; M4 = 2- isopropoxyphenylcarbamic acid; M5 = isopropoxyphenyl-hydroxy(-) methylcarbamate; M6 = 2-isopropoxy-5-hydroxyphenyl-methylcarbamate; M7 = 2-isopropoxy-5-hydroxyphenyl carbamic acid; M8 = 2-isopropoxy-5-hydroxyphenylhydroxymethyl carbamate; M9 = 1,5-dihydroxy-2-isopropoxybenzene. In additional studies, M6 (= 2-isopropoxy-5-hydroxyphenylmethylcarbamate) was identified as a principle metabolite in hamsters, mice, and humans. The nitrosated compound M9A ( = 1-hydroxy-2- isopropoxy-4-nitrobenzene) has been identified as a metabolite in rats and mice, the rhesus monkey, and humans. Evidence from the human study suggests that M9A is synthesized in the stomach.

代谢
5只雌性大鼠一组分别在其饮食中接受了含有50、250或500 ppm未标记敌敌畏的饲料,持续5个月,然后在口服灌胃的方式下接受了一次1 mg/kg的放射性标记物质的剂量。在给药后0到24小时内采集的尿样中,总放射性标记的87.9%至99.8%被检测到;通过薄层色谱法发现,97-98%的活性保持在原点,并包含在结合代谢物和/或未知结构的极性代谢物中。通过酶切,80-86%的活性被识别为特定的代谢物,包括M1、M2、M3、M4、M5、M6、M7、M8,以及M6CII(= 2-异丙氧基-5-羟基苯基氨基甲酸)、MS3(= 2-异丙氧基-5-羟基苯基-羟甲基氨基甲酸)和M7A(= 2-异丙氧基-3-羟基苯基-甲基氨基甲酸)。
Groups of 5 female rats received 50, 250, or 500 ppm unlabeled propoxur in their diets for 5 months, then received (by oral gavage) a single dose of 1 mg/kg radiolabelled material. Urine samples taken in the period from 0 to 24 hr after dosage had 87.9 to 99.8% of the total radiolabel; by thin layer chromatography it was found that 97-98% of the activity remained at the origin, and was contained in conjugated metabolites and/or extremely polar metabolites of unknown structure. By enzymatic cleavage 80-86% of the activity was identified as specific metabolites including M1, M2, M3, M4, M5, M6, M7, M8, as well as M6CII (= 2-isopropoxy-5-hydroxyphenyl carbamic acid), MS3 (= 2-isopropoxy-5-hydroxyphenyl-hydroxymethyl carbamate, and M7A (= 2- isopropoxy-3-hydroxyphenyl-methyl carbamate).

  • 毒性总结
Propoxur是一种胆碱酯酶乙酰胆碱酯酶(AChE)抑制剂氨基甲酸酯通过与酶的活性位点上的氨基甲酸化形成与胆碱酯酶的不稳定复合物。这种抑制作用是可逆的。胆碱酯酶抑制剂抑制乙酰胆碱酯酶的作用。由于其基本功能,干扰乙酰胆碱酯酶作用的化学物质是强效的神经毒素,即使在低剂量下也会导致过度流涎和眼泪。在更高剂量的暴露下,头痛、流涎、恶心、呕吐、腹痛和腹泻常常很明显。乙酰胆碱酯酶分解神经递质乙酰胆碱,该递质在神经和肌肉接头处释放,以便让肌肉或器官放松。乙酰胆碱酯酶抑制的结果是乙酰胆碱积累并继续作用,使得任何神经冲动持续传递,肌肉收缩不会停止。
Propoxur is a cholinesterase or acetylcholinesterase (AChE) inhibitor. Carbamates form unstable complexes with chlolinesterases by carbamoylation of the active sites of the enzymes. This inhibition is reversible. A cholinesterase inhibitor suppresses the action of acetylcholine esterase. Because of its essential function, chemicals that interfere with the action of acetylcholine esterase are potent neurotoxins, causing excessive salivation and eye-watering in low doses. Headache, salivation, nausea, vomiting, abdominal pain and diarrhea are often prominent at higher levels of exposure. Acetylcholine esterase breaks down the neurotransmitter acetylcholine, which is released at nerve and muscle junctions, in order to allow the muscle or organ to relax. The result of acetylcholine esterase inhibition is that acetylcholine builds up and continues to act so that any nerve impulses are continually transmitted and muscle contractions do not stop.

  • 健康影响
急性暴露于胆碱酯酶抑制剂可能会导致胆碱能危象,表现为严重的恶心/呕吐、流涎、出汗、心动过缓、低血压、衰竭和抽搐。肌肉无力可能性增加,如果呼吸肌肉受累,可能导致死亡。在运动神经积累的乙酰胆碱会导致神经肌肉接头处烟碱表达的过度刺激。当这种情况发生时,可以看到肌肉无力、疲劳、肌肉痉挛、肌肉跳动和麻痹的症状。当自主神经节积累乙酰胆碱时,这会导致交感系统中烟碱表达的过度刺激。与此相关的症状是高血压和低血糖。由于乙酰胆碱积累,中枢神经系统中烟碱乙酰胆碱受体的过度刺激会导致焦虑、头痛、抽搐、共济失调、呼吸和循环抑制、震颤、全身无力,甚至可能昏迷。当由于副交感神经乙酰胆碱受体处乙酰胆碱过多而出现毒蕈碱过度刺激时,可能会出现视力障碍、胸部紧绷、由于支气管收缩引起的喘息、支气管分泌物增加、唾液分泌增加、流泪、出汗、肠蠕动和排尿的症状。长期高(>10年)暴露会导致神经心理学后果,包括感知和视觉运动处理的干扰(A15321)。
Acute exposure to cholinesterase inhibitors can cause a cholinergic crisis characterized by severe nausea/vomiting, salivation, sweating, bradycardia, hypotension, collapse, and convulsions. Increasing muscle weakness is a possibility and may result in death if respiratory muscles are involved. Accumulation of ACh at motor nerves causes overstimulation of nicotinic expression at the neuromuscular junction. When this occurs symptoms such as muscle weakness, fatigue, muscle cramps, fasciculation, and paralysis can be seen. When there is an accumulation of ACh at autonomic ganglia this causes overstimulation of nicotinic expression in the sympathetic system. Symptoms associated with this are hypertension, and hypoglycemia. Overstimulation of nicotinic acetylcholine receptors in the central nervous system, due to accumulation of ACh, results in anxiety, headache, convulsions, ataxia, depression of respiration and circulation, tremor, general weakness, and potentially coma. When there is expression of muscarinic overstimulation due to excess acetylcholine at muscarinic acetylcholine receptors symptoms of visual disturbances, tightness in chest, wheezing due to bronchoconstriction, increased bronchial secretions, increased salivation, lacrimation, sweating, peristalsis, and urination can occur. Chronically high (>10 years) exposure leads to neuropsychological consequences including disturbances in perception and visuo-motor processing (A15321).

吸收、分配和排泄
在代谢研究中使用了七只雄性大鼠;一只仅接受非标记的毒死蜱;其他接受1毫克/千克(14)C标记的(环状)毒死蜱,并在1、4、8、24、48和72小时时处死。将这些大鼠沿矢状面切开,并直接接触X光片暴露(29-124天)。1小时时,除了骨骼,所有器官(尤其是肠道)中都能检测到放射性。24小时后,胃肠道、膀胱以及咽部区域的粘膜中有高浓度的放射性。在48小时和72小时,肝脏、肾脏和咽部系统的粘膜中仍可检测到一些放射性。毒死蜱(及其代谢物)通过淋巴系统分布的情况得到了展示。
... Seven male rats were used /in a metabolic study/; one received only non-labeled propoxur; the others received 1 mg/kg (14)C-labeled (ring) with sacrifice at 1, 4, 8, 24, 48, and 72 hr. The rats were sagittally sectioned and exposed (29-124 days) in direct contact with X-ray film. At 1 hour, radioactivity was detectable in all organs (particularly intestines) except the bone. After 24 hr, there were high concentrations of radioactivity in the gastrointestinal tract and bladder, as well as the mucous membranes of the pharyngeal region. At 48 and 72 hr, some radioactivity was still detectable in the liver, kidneys and mucous membranes of the pharyngeal system. Propoxur (and/or its metabolites) was shown to be distributed via the lymph system.

吸收、分配和排泄
两项研究提供了关于人类和老鼠皮肤对丙氧的吸收信息。在人类研究中,六名个体接受了一次静脉注射的(14)C-丙氧,剂量为1 Ci/mL。在剂量后的五天内收集全部尿液,并确定尿液中排出的放射性标记剂量的百分比。随后,这六名个体接受了一次皮肤剂量的(14)C-丙氧,剂量为4微克/平方厘米,暴露时间为24小时。在剂量后的五天内收集全部尿液,并确定尿液中排出的放射性标记剂量的百分比。排出的放射性标记物量经过了静脉注射剂量后排出的81.8%的校正。校正后的总排泄量为皮肤给药剂量的19.6%。在老鼠研究中,给老鼠(未给出品种和性别)施用了四个剂量(0.648、6.91、69.5和692微克/平方厘米),持续时间为0.5、1、2、4、8和24小时。测试材料在乙醇中给药,乙醇是一种可以增加溶解化学物质吸收的溶剂。由于吸收百分比随剂量的非线性减少,选择了6.91微克/平方厘米的剂量(最接近人类研究中给药剂量的剂量)与人类研究进行比较。结果显示(对于0.5、1、2、4、8和32小时的持续时间),吸收率分别为7.88%、10.2%、17.9%、23.2%和32.5%。在老鼠研究中,对于8小时和24小时的暴露时间,吸收的百分比超过了人类研究的吸收百分比。这是预期的,即使没有添加乙醇,因为老鼠皮肤的渗透性比人类皮肤强。另外,如果在人类研究中使用丙酮,将会显示出丙氧渗透的预期增加。
Two studies ... provide information on the dermal adsorption of propoxur in humans and rats. In the human study, six individuals received a single intravenous dose of (14)C-propoxur, 1 Ci/mL. Total urine was collected for five days post-dose and the percent of radiolabeled-dose excreted in the urine was determined. Subsequently the same six individuals received a single dermal dose of (14)C-propoxur at 4 ug/sq cm for an exposure period of 24 hr. Total urine was collected for five days post-dose and the percent of radiolabeled-dose excreted in the urine was determined. The radiolabel excreted was corrected for the 81.8% of label excreted following the iv dose. Corrected total excretion was 19.6 percent of the dermally administered dose. In the rat study, four doses (0.648, 6.91, 69.5, and 692 ug/sq cm) were administered /to rats (strain and sex not given)/ for durations of 0.5, 1, 2, 4, 8, and 24 hr. Test material was administered in ethanol, a solvent which can increase the absorption of a dissolved chemical. Since percent absorption decreases in a nonlinear manner with dose, the absorption from the dose of 6.91 ug/sq cm (the nearest dose to that administered in the human study) was selected for comparison with the human study. The results indicate (for durations 0.5, 1, 2, 4, 8, and 32 hr) a total of 7.88, 10.2, 17.9, 23.2, and 32.5% absorption, respectively. The percent absorbed in the rat study exceeds the percent absorbed in the human study for exposure durations of 8 and 24 hr. This is expected, even without the addition of ethanol, as rat skin is more permeable than human skin. Alternatively, the use of acetone in the human study would show an expected increase of propoxur penetration.

吸收、分配和排泄
在大鼠的皮肤吸收研究中,使用50%乙醇和50%的混合物作为溶剂,以0.648、6.91、69.5或692微克/平方厘米的剂量(相应名义剂量分别为:0.009875、0.105、1.0625和10.5毫克)施用放射性标记的丙氧。在两个最低剂量平上观察到最高的吸收值(50至64.9%),在给药后0.5至1.0小时内,这两个剂量平在血液中放射性活性的百分比最高(0.1-0.18%)。由于丙氧是涂覆在乙醇的混合物中,因此获得的皮肤吸收值可能比仅用作为溶剂时要高一些。
In a dermal absorption study with rats, a mixture of 50% ethanol and 50% water was used as a solvent, with doses of 0.648, 6.91, 69.5, or 692 ug/sq cm (corresponding nominal doses: 0.009875, 0.105, 1.0625, and 10.5 mg, respectively) radiolabeled propoxur. The highest values for absorption (50 to 64.9%) were observed with the two lowest dose levels, with the highest percentages of radioactivity (0.1-0.18%) in the blood occurring at these dose levels at 0.5 to 1.0 hr after dosage. Because propoxur was applied in a mixture of ethanol and water, the values obtained for dermal absorption were probably somewhat higher than if water alone had been the solvent.
