... FENTHION IS METABOLIZED IN PLANTS INITIALLY TO SULFOXIDE. THE METABOLIC CONVERSION OF THIOETHER GROUP TO SULFOXIDE IS RAPID & SUBSEQUENT METAB TO SULFONE & DESULFURATION TO PHOSPHATE SULFOXIDE & SULFONE IS SLOWER.
... STABLE FLY & BED BUG RAPIDLY METABOLIZED FENTHION. OXIDATION OCCURRED AT THIOPHOSPHORYL & THIOETHER POSITIONS. LATTER PATH PRODUCED FENTHION SULFOXIDE & FENTHION SULFONE. OTHER PATH GAVE RISE TO FENOXON & 4-METHYLSULFONYL-M-CRESOL. THE SULFINYL CRESOL ANALOG WAS ALSO OBSERVED. THE HYDROLYTIC PRODUCTS WERE CONJUGATED & EXCRETED. FOLLOWING CONVERSION TO THE OXYGEN ANALOG, OXIDATION OF THIOETHER WAS MORE RAPID.
FOURTEEN DAYS AFTER APPLICATION /TO RICE PLANTS/, WATER SOL METABOLITES WERE FOUND IN RICE GRAINS: PHOSPHATE & THIOPHOSPHATE, DIMETHYL PHOSPHATE & THIOPHOSPHATE, DEMETHYL FENTHION, & UNKNOWN CMPD.
FENTHION SULFOXIDE & SULFONE & FENTHION PHOSPHATE SULFOXIDE OR SULFONE HAVE BEEN IDENTIFIED IN HOUSEFLIES AFTER TOPICAL APPLICATION ... . AT LEAST 5 INTACT ESTER DERIVATIVES OF FENTHION HAVE BEEN ISOLATED FROM BOLL WEEVIL, GERMAN COCKROACHES, & RATS.

代谢
Fenthion 已知的人类代谢物包括 Fenthion oxon。
Fenthion has known human metabolites that include Fenthion oxon.
Fenthion 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.

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. Certain reproductive effects in fertility, growth, and development for males and females have been linked specifically to organophosphate pesticide exposure. Most of the research on reproductive effects has been conducted on farmers working with pesticides and insecticdes in rural areas. In females menstrual cycle disturbances, longer pregnancies, spontaneous abortions, stillbirths, and some developmental effects in offspring have been linked to organophosphate pesticide exposure. Prenatal exposure has been linked to impaired fetal growth and development. Neurotoxic effects have also been linked to poisoning with OP pesticides causing four neurotoxic effects in humans: cholinergic syndrome, intermediate syndrome, organophosphate-induced delayed polyneuropathy (OPIDP), and chronic organophosphate-induced neuropsychiatric disorder (COPIND). These syndromes result after acute and chronic exposure to OP pesticides.
