代谢

2-氯苯酚在胃和小肠中被吸收。通过胃肠道的吸收是通过简单扩散，预计会非常迅速且几乎完全。2-氯苯酚的代谢主要是通过结合作用。主要排泄的代谢物是葡萄糖苷酸。其他代谢物包括醚硫酸盐等硫酸结合物。这些代谢物通过尿液排出。

Absorption of 2-chlorophenol is favored in the stomach and the intestine. Absorption through the gastrointestinal tract is by simple diffusion and is expected to be both rapid and virtually complete.The metabolism of the 2-chlorophenol is principally via conjugation. The principal metabolite excreted is the glucuronide. Other metabolites are sulfate conjugates such as the ethereal sulfate. The metabobites are excreted in urine (L159).

毒理性

• 毒性总结

2-氯苯酚作为氧化磷酸化解偶联的弱剂和细胞呼吸的抑制剂。随着氯化程度的增加，氯苯酚解偶联氧化磷酸化的能力增强。实际上，研究表明氯苯酚对磷酸化和细胞呼吸的影响与浓度有关，呈现三阶段效应。在低浓度下，解偶联会导致静息状态呼吸的刺激，这是由于在没有磷酸盐受体的情况下腺苷三磷酸酶（ATP酶）活性增加的结果。也观察到活动性呼吸的抑制。在中等浓度下，静息呼吸既不被刺激也不被抑制。在非常高的浓度下，会出现显著的呼吸抑制，伴随着电子传递过程的破坏和ATP酶活性的降低。解偶联活性归因于质子传递效应（氯苯酚在膜磷脂双层中的分布导致线粒体膜上的能量梯度破坏），而细胞呼吸的抑制归因于对细胞内蛋白的直接作用（L159）。

2-chlorophenol works as a weak uncoupler of oxidative phosphorylation and inhibitors of cellular respiration. The ability of chlorophenols to uncouple oxidative phosphorylation increases with increasing chlorination. In fact, studies indicate a concentration-dependent triphasic effect of chlorophenols on phosphorylation and cellular respiration. At low concentrations, uncoupling produces stimulation of the resting state respiration as a result of increased adenosine triphosphatase (ATPase) activity in the absence of a phosphate acceptor.Inhibition of active respiration is also observed. At moderate concentrations, resting respiration is neither stimulated nor inhibited. Significant inhibition of respiration, associated with a breakdown of the electron transport process and decreased ATPase activity, occurs at very high concentrations. Uncoupling activity has been attributed to a protonophoric effect (a disruption of the energy gradient across the mitochondrial membrane resulting from distribution of chlorophenols in the phospholipid bilayer of the membrane), whereas inhibition of cellular respiration has been attributed to a direct action on intracellular proteins (L159).

• 健康影响

2-氯苯酚对上皮组织具有腐蚀性。当其应用于角膜时，可产生从轻微充血到严重腐蚀的各种效果。急性吸入暴露可能导致肺部出血和呼吸急促。口服暴露于2-氯苯酚可能产生多种神经系统效应，包括震颤、肌阵挛性抽搐、驼背姿势、呼吸困难、瘫痪和昏迷（L159）。

2-chlorophenol is corrosive to epithelial tissue. It produce effects ranging from slight hyperemia to severe corrosion when applied to the corneas. Acute inhalation exposure may lead to hemorrhage in the lungs and tachypnea. Oral exposure to 2-chlorophenol can produce a variety of neurological effects, including tremors, myoclonic convulsions, a hunched posture, dyspnea, collapse, and coma (L159).

吸收、分配和排泄

许多兔子的研究表明，单氯酚的代谢主要是通过结合作用进行的。在/一个/研究中，将6只兔子分成一组，通过灌胃方式一次性给予171.3 mg/kg的2-CP或4-CP，将其乳化在水中。对于两种异构体，24小时尿液分析表明，78.1%到88.3%的给药剂量以葡萄糖苷酸形式排出，12.8%到20.6%的给药剂量以醚硫酸盐形式排出。总的来说，分别有101.7%和101.1%的2-CP或4-CP给药剂量以尿液中的葡萄糖苷酸和硫酸盐结合物形式被计算在内。

A number of rabbit studies have shown that metabolism of the monochlorophenols is principally via conjugation. In /one/ study, groups of 6 rabbits were treated by gavage with 171.3 mg/kg of 2-CP or 4-CP emulsified in water as a single dose. For both isomers, the 24-hour urine analysis indicated that between 78.1 and 88.3% of the administered dose was excreted as the glucuronide, and between 12.8 and 20.6% of the administered dose was excreted as the ethereal sulfate. A total of 101.7 and 101.1% of the administered 2-CP or 4-CP doses, respectively, was accounted for as urinary glucuronide and sulfate conjugates.

吸收、分配和排泄

一般来说，氯酚类物质很容易通过皮肤被吸收。使用无毛小鼠的皮肤进行实验，2-MCP、2,4-DCP和2,4,6-T3CP的水溶液可以轻易地渗透皮肤，前提是该化合物没有离子化。在体外研究中，从尸检中取得的人类皮肤表皮膜显示出2-MCP、4-MCP、2,4-DCP和2,4,6-T3CP的渗透。溶质的亲脂性特征和它们的氢键能力是决定这种渗透的两个主要特性。

In general, chlorophenols are readily absorbed through the skin. Using the skin of the hairless mouse, aqueous solutions of 2-MCP, 2,4-DCP, and 2,4,6- T3CP readily penetrated the skin, provided that the compound was not ionized. In vitro studies on epidermal membranes from human skin taken at autopsy showed penetration by 2-MCP, 4-MCP, 2,4-DCP, and 2,4,6-T3CP. The lipophilic character of the solutes and their hydrogen-bonding capacity are the 2 main features determining this penetration.
