物理描述:
Methoxychlor is a white crystalline solid which is often dissolved in a liquid carrier such as diesel oil. It can cause illness by inhalation, skin absorption and/or ingestion. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. If dissolved in a liquid carrier, it can easily penetrate the soil and contaminate groundwater and nearby streams. It is used as a pesticide.

Methoxychlor will attack some forms of plastics, rubbers, and coatings.
Although methoxychlor is slowly metabolized to small extent by pathways similar to those of DDT. ... the major ... pathway ... is by o-demethylation and subsequent conjugation. ... These pathways are catalyzed by microsomal enzymes in mammals and by enzymes in soil organisms ... .
In mice, 98% of labeled methoxychlor given orally was eliminated within 24 hr. Main metabolic pathway ... o-dealkylation to 2-(para-hydroxyphenyl)-2-(para-methoxyphenyl)-1,1,1-trichloroethane, 2,2-bis(para-hydroxyphenyl)-1,1,1-trichloroethane and its ethylene, and 4,4'-dihydroxybenzophenone which were excreted mainly as conjugates.
(14)C-labeled methoxychlor was given orally to intact, colostomized, and bile-fistulated chickens. Recovery of (14)C was greater in carcasses of hens compared to roosters for comparable dosages and time. (14)C in eggs varied with dose and time and was predominantly in yolk. 26 metabolites were either identified or characterized: 22 metabolites in feces, 14 in urine, and 6 in bile. Metabolism incl demethylation, ring hydroxylation, conjugation with glucuronic acid, dechlorination, dehydrochlorination, and formation of substituted benzophenones. Chem structures of some metabolites are provided in the article.
(14)C-labeled methoxychlor was given orally to a bile-cannulated goat and via skin surface to 2 other goats. At the end of 3 days, seven metabolites plus methoxychlor were isolated from the bile. These were 1,1-dichloro-2,2-bis(4-methoxyphenyl)ethene, 1,1-dichloro-2,2-bis(4-methoxyphenyl)ethane, 1,1,1-trichloro-2-(4-hydroxyphenyl)-2-(4-methoxyphenyl)ethane, 1,1-dichloro-2-(4-hydroxyphenyl)-2-(4-methoxyphenyl)ethene, 1,1-dichloro-2-(4-hydroxyphenyl)-2-(4-methoxyphenyl)ethane, 1,1-dichloro-2,2-bis(4-hydroxyphenyl)ethene, and 1,1-dichloro-2,2-bis-(4-hydroxyphenyl)ethane.

Methoxychlor has known human metabolites that include Mono-hydroxy-methoxychlor.
Certain mono- and bis-hydroxy metabolites of methoxychlor, especially 2,2-bis(p-hydroxyphenyl)-1,1, 1-trichloroethane (HPTE), act as estrogen analogues. HPTE is an estrogen receptor alpha agonist, and also acts as an antagonist at the estrogen receptor beta and androgen receptor. This affects protein synthesis, which is believed to cause many of methoxychlor's estrogenic effects, such as decreased fertility. As methoxychlor is also a structural analogue of DDT, it is believed to have the same neurotoxic effects. This includes preventing the deactivation of the sodium gate after neuron activation and membrane depolarization, resulting in hyperexcitability of the nerve. Like DDT, methoxychlor may also inhibit neuronal adenosine triphosphatases (ATPases), particularly Na+K+-ATPase and Ca2+-ATPase, which play vital roles in neuronal repolarization. This contributes to the reduced rate of depolarization and increases the sensitivity of neurons to small stimuli that would not elicit a response in a fully depolarized neuron. (T10, A118)

喂食标记甲氧滴滴涕的老鼠收集了尿液和粪便。在回收的放射性物质中,90%在粪便中,10%在尿液中。
Urine and feces were collected from mice fed labeled methoxychlor. Of recovered radioactivity, 90% was in feces and 10% in urine.
(14C-1-Phenyl)-methoxychlor in oil emulsion given iv to rats at dose of 1 mg in 0.5 mL emulsion was metabolized rapidly by liver to unidentified hydrophilic products, which were excreted mainly in feces, by secretion from liver into bile, and to lesser extent in urine. Very little reabsorption occurred from GI tract.
Weanling rats fed 500 mg/kg diet methoxychlor for 4-18 wk stored 14-36 mg/kg in fat. Equilibrium was reached within 4 wk & methoxychlor disappeared from fatty tissue within 2 wk after end of exposure. Rats fed 100 mg/kg stored 1-7 mg/kg. No methoxychlor ... stored in animals given 25 mg/kg diet, & no sex differences in storage ... .
