• 説明

  Trichlorfon is a colorless crystalline powder. It is soluble in water (120 g/L) and most organic solvents, except aliphatic hydrocarbons. Log Kow = 0.43. Trichlorfon is rapidly converted to dichlorvos by alkalis (2) and then hydrolyzed; DT₅₀ (22 ?C) values at pH 4, 7, and 9 are 510 d, 46 h, and <30 min, respectively.

• 化学的特性

  Trichlorfon is a white to pale yellow crystalline solid.

• 使用

  Trichlorfon is an irreversible organophosophate acetylcholinesterase inhibitor and the prodrug of Dichlorvos (D435950). Trichlorfon have also shown potential actions to be utilized as an effective org anophosphorus pesticide.

• 定義

  ChEBI: A phosphonic ester that is dimethyl phosphonate in which the hydrogen atom attched to the phosphorous is substituted by a 2,2,2-trichloro-1-hydroxyethyl group.

• 適応症

  Metrifonate is an organophosphorous compound that is effective only in the treatment of S. haematobium. The active metabolite, dichlorvos, inactivates acetylcholinesterase and potentiates inhibitory cholinergic effects. The schistosomes are swept away from the bladder to the lungs and are trapped. Therapeutic doses produce no untoward side effects except for mild cholinergic symptoms. It is contraindicated in pregnancy, previous insecticide exposure, or with depolarizing neuromuscular blockers. Metrifonate is not available in the United States.

• 抗菌性

  Useful activity is restricted to Schistosoma haematobium. It has little activity against other schistosomes. Although it exhibits activity against several other helminths, it is not used for their treatment.

• 一般的な説明

  Chlorophos is a white crystalline solid. Soluble in water, benzene, chloroform, ether; insoluble in oils. Chlorophos is a wettable powder. Chlorophos can cause illness by inhalation, skin absorption and/or ingestion. Chlorophos is used as a pesticide.

• 空気と水の反応

  Chlorophos decomposes at higher temperatures in water and at pH <5.5. Chlorophos is sensitive to prolonged exposure to moisture. Chlorophos is unstable in alkaline solutions.

• 反応プロフィール

  Chlorophos is incompatible with alkalis. Chlorophos is corrosive to black iron and mild steel. Chlorophos is corrosive to metals. Chlorophos is subject to hydrolysis.

• 健康ハザード

  INHALATION, INGESTION, AND SKIN ABSORPTION. Inhibits cholinesterase. Headache, depressed appetite, nausea, miosis are symptoms of light exposures. Moderate effects are peritoneal paralysis, diarrhea, salivation, lacrimation, sweating, dyspnea, substernal tightness, slow pulse, tremors, muscular cramps and ataxia. Severe symptoms are: pyrexia, cyanosis, pulmonary edema, areflexia, loss of sphincter control, paralysis, coma, heart block, shock and respiratory failure. EYES: Increases permeability of blood vessels in anterior eye. Reduces corneal sensitivity with glaucoma, abnormalities in intraocular tension or decreased visual acuity.

• 火災危険

  Combustible material: may burn but does not ignite readily. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.

• 応用例（製薬）

  An organophosphorus compound. It is soluble in water and stable at room temperature. At higher temperatures it decomposes to the insecticide dichlorvos.

• 薬物動態学

  Metrifonate is rapidly absorbed after oral administration, achieving a peak concentration in plasma within 1–2 h. It undergoes chemical transformation to dichlorvos, which is the active molecule. Dichlorvos is rapidly and extensively metabolized and excreted mainly in the urine.

• 臨床応用

  Urinary schistosomiasis (especially mass chemotherapy control programs)

• 副作用

  Various side effects such as abdominal pain, gastrointestinal upsets and vertigo occur in many patients. As the worms release their hold of the veins in the bladder they pass through the blood system to the lungs, where they disintegrate; this may cause some of the side effects. Cholinesterase levels in the blood and on erythrocytes are depressed, but the significance of this is unknown.

• 安全性プロファイル

  Poison by ingestion, inhalation, inti-aperitoneal, subcutaneous, intravenous, and intramuscular routes. Moderately toxic by skin contact. Human systemic effects: true cholinesterase. Experimental teratogenic and reproductive effects. Questionable carcinogen with experimental carcinogenic and tumorigenic data. Human mutation data reported. An eye irritant. When heated to decomposition it emits very toxic fumes of Cland POx.

• 職業ばく露

  Trichlorfon is used as an agricultural and forest insecticide.

• 発がん性

  When rats were fed diets that contained 0, 50, 100, 200, 250, 400, 500, or 1000 ppm (equivalent to about 0.5, 12.5, 25, or 50 mg/kg/day) for 17 or 24 months, no treatment-related effects occurred in those fed 50–250 ppm . Histopathological results suggested the occurrence of mammary tumors in rats fed 400, 500, and 1000 ppm. In another study, when rats were fed diets containing 0, 50, 250, 500, or 1000 ppm (equivalent to about 2.5, 12.5, 25, or 50 mg/kg/day) trichlorfon for 24 months, no treatment-related effects other than whole-blood cholinesterase depression at 1000 ppm occurred . There was no increase in the incidence of either benign or malignant tumors, including mammary tumors.

• 環境運命予測

  Soil. Trichlorfon degraded in soil to dichlorvos (alkaline conditions) and desmethyl dichlorvos (Mattson et al., 1955).
  Plant. In cotton leaves, the metabolites identified included dichlorvos, phosphoric acid, O-demethyl dichlorvos, O-demethyl trichlorfon, methyl phosphate and dimethyl phosphate (Bull and Ridgway, 1969). Chloral hydrate and trichloroethanol were r
  Pieper and Richmond (1976) studied the persistence of trichlorfon in various foliage following an application rate of 1.13 kg/ha. Concentrations of the insecticide found at day 0 and 14 were 81.7 ppm and 7 ppb for willow foliage, 12.6 ppm and 670 ppb for
  Chemical/Physical. At 100°C, trichlorfon decomposes to chloral. Decomposed by hot water at pH <5 forming dichlorvos (Worthing and Hance, 1991).

• 代謝

  Trichlorfon administered to mammals is rapidly metabolized and excreted almost completely in the urine within 6 h. Majormetabolites are dimethyl hydrogen phosphate, methyl dihydrogen phosphate, and conjugates of dichloroacetic acid and trichloroethanol. Trichlorfon is rapidly broken down in soil.

• 輸送方法

• 不和合性

  This chemical may be characterized as an organo-phosphate or-chlorine compound. Organophosphates are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducin g agents such as hydrideds and active metals. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.Alkaline materials: lime, lime sulfur, etc. Corrosive to iron, steel and possibly to other metals.
