代谢

细菌分离株，与腐生性棒状细菌有关，能够以五氯苯酚作为唯一的碳源和能源进行代谢。五氯苯酚迅速被代谢成二氧化碳。在绿僵菌的培养中，五氯苯酚被甲基化形成五氯茴香醚。同样，五氯茴香醚也通过曲霉属和头花霉属的五氯苯酚形成。

Bacterial isolate, related to saprophytic coryneform bacteria, was able to metabolize pentachlorophenol as sole source of carbon and energy. Pentachlorophenol was rapidly metabolized to CO2. In cultures of Trichoderma virgatum, pentachlorophenol was methylated to form pentachloroanisole. Similarly, pentachloroanisole was formed from pentachlorophenol by Penicillium sp and Cephaloascus fragrans.

毒理性

• 毒性总结

五氯苯酚是一种胆碱酯酶或乙酰胆碱酯酶（AChE）抑制剂。胆碱酯酶抑制剂（或“抗胆碱酯酶”）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大的神经毒素，低剂量时会导致过度流涎和眼泪，随后是肌肉痉挛，最终导致死亡。神经气体和许多用于杀虫剂的物质已被证明通过结合乙酰胆碱酯酶活性位点的丝氨酸，完全抑制该酶。乙酰胆碱酯酶分解神经递质乙酰胆碱，后者在神经和肌肉接头处释放，以允许肌肉或器官放松。乙酰胆碱酯酶抑制的结果是乙酰胆碱积聚并继续发挥作用，使得任何神经冲动不断传输，肌肉收缩不会停止。最常见的乙酰胆碱酯酶抑制剂之一是基于磷的化合物，它们被设计成与酶的活性位点结合。结构要求是一个带有两个亲脂性基团的磷原子，一个离去基团（如卤素或硫氰酸盐）以及一个末端的氧。

Pentachlorophenol is a cholinesterase or acetylcholinesterase (AChE) inhibitor. A cholinesterase inhibitor (or 'anticholinesterase') suppresses the action of acetylcholinesterase. Because of its essential function, chemicals that interfere with the action of acetylcholinesterase are potent neurotoxins, causing excessive salivation and eye-watering in low doses, followed by muscle spasms and ultimately death. Nerve gases and many substances used in insecticides have been shown to act by binding a serine in the active site of acetylcholine esterase, inhibiting the enzyme completely. 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. Among the most common acetylcholinesterase inhibitors are phosphorus-based compounds, which are designed to bind to the active site of the enzyme. The structural requirements are a phosphorus atom bearing two lipophilic groups, a leaving group (such as a halide or thiocyanate), and a terminal oxygen.

In addition, a high incidence of two uncommon tumors (adrenal medulla pheochromocytomas and hemangiomas/hemangiosarcomas) was observed with both preparations.

本研究的目标是了解多氯联苯（PCBs）、特定羟基化多氯联苯代谢物（OH-PCBs）和五氯酚（PCP）在东部斯洛伐克出生队列的脐带血血清中的胎盘传递情况。在2002-2004年期间，从斯洛伐克东部米哈尔奥夫采和斯维德尼克/斯特罗波夫两个地区的分娩妇女中平行收集脐带血标本和母体标本。本研究选择了92对母婴标本。定量分析了4-OH-CB107、3-OH-CB153、4-OH-CB146、3'-OH-CB138、4-OH-CB187和4'-OH-CB172。脐带血清中Sigma(17)PCBs、Sigma(6)OH-PCBs和PCP的中位浓度分别为0.92、0.33和0.69 ng/g湿重，与相应母体血清水平高度相关（相关系数分别为R(2) = 0.61、0.78和0.82）。脐带与母体Sigma(17)PCBs、Sigma(6)OH-PCBs和PCP的中位比值分别为0.18、0.75和1.10。脐带血清中Sigma(6)OH-PCBs与Sigma(17)PCBs的中位比值基于湿重浓度为0.38，是母体血清中这些化合物比值的约四倍（0.09）。PCP在脐带血清中的含量比任何测量的PCB或OH-PCB同系物都要丰富。与母体相比，OH-PCB代谢物的脐带与母体比值较高，这表明要么是胎盘传递率更高，要么是胎儿相对于母体部分的代谢更多。这些发现与它们优先与能够穿越胎盘的TTR结合一致。脐带与母体的比值因同系物而异（例如，4-OH-CB107 = 0.58，4-OH-CB146 = 0.74，3'-OH-CB138 = 1.01）。

The aim of the present study was to understand the placental transfer of polychlorinated biphenyls (PCBs), specific hydroxylated PCB metabolites (OH-PCBs), and pentachlorophenol (PCP) in blood serum, in a birth cohort from eastern Slovakia. During the period 2002-2004, cord blood specimens were collected in parallel with maternal specimens from women delivering in the two eastern Slovak districts of Michalovce and Svidnik/Stropkov. A total of 92 pairs of mother-cord specimens at delivery were selected for this study. 4-OH-CB107, 3-OH-CB153, 4-OH-CB146, 3'-OH-CB138, 4-OH-CB187, and 4'-OH-CB172 were quantified. The median concentrations of Sigma(17)PCBs, Sigma(6)OH-PCBs, and PCP in cord serum were 0.92, 0.33, and 0.69 ng/g wet wt, respectively, and highly correlated with the corresponding maternal serum levels (correlations were R(2) = 0.61, 0.78, and 0.82, respectively). The median cord to mother ratios of the Sigma(17)PCBs, Sigma(6)OH-PCBs, and PCP were 0.18, 0.75, and 1.10, respectively. The median ratio of the Sigma(6)OH-PCBs to the Sigma(17) PCBs in the cord serum was 0.38 from wet wt based concn, which was about four times higher than the ratio of these compounds in maternal serum (0.09). PCP was more abundant than any PCB or OH-PCB congener measured in cord serum. The higher cord to maternal ratios of OH-PCB metabolites as compared with the parent cmpd suggests either a higher placental transfer rate or greater metabolism in the fetus as compared with the maternal compartment. These findings are consistent with their preferential binding to TTR that can cross the placenta. The cord to maternal ratio varies by congener (e.g., 4-OH-CB107 = 0.58, 4-OH-CB146 = 0.74, 3'-OH-CB138 = 1.01).

制备方法与用途

制备方法

1. 将固体氢氧化钠加入搅拌槽中，搅拌状态下加水配制成约160g/L的溶液。接着，在搅拌条件下，按六氯苯与氢氧化钠摩尔比为1∶(2.5～2.6)的比例，将六氯苯逐步加入碱液中，搅拌均匀后通过泵送入高压水解釜中。待搅拌升温至釜内压力达2.0MPa时，停止加热。由于反应放热，反应釜内温度会自动升至约230℃，同时釜内压力达到2.55MPa。保持此温度反应20分钟，水解即完成。随后泄压出料，冷却结晶、过滤即可得到鳞片状固体五氯酚钠。

2. 将上述制得的五氯酚钠加入至反应釜中，在搅拌条件下逐步加入31%的盐酸进行酸化处理，控制温度在80～90℃。待酸化完全后，产物通过水洗、过滤和干燥步骤即可获得最终产品。

3. 由三氯苯经通氯氯化得到六氯苯；随后将六氯苯与一定浓度的烧碱溶液共同加热升温，在设定的温度及压力条件下进行水解反应。反应结束后，经过冷却、结晶、过滤以及干燥过程可最终制得五氯酚钠。
