Vernolate 在活小鼠中产生亚砜降解产物。/来自表格/
Vernolate gives sulfoxide degradation product in living mice. /from table/
Thiocarbamates are detected in the liver of mice 20 min after ip treatment with EPTC, molinate, pebulate, and vernolate at 1 m mole/kg but not after administration of benthiocarb, butylate, or cycloate.
One of the two major metabolic pathways for thiocarbamates in mammals is sulfoxidation, followed by conjugation with glutathione (GSH) by GSH S -transferase. The GSH conjugate is then cleaved to the cysteine derivative, which is subsequently acetylated and excreted as S -carbamoyl-mercapturic acid. ...Sulfoxidation of thiocarbamates such as EPTC, molinate, pebulate, and vernolate undoubtedly represents a detoxification mechanism in mammals, the sulfoxides generally being less toxic than the parent compounds. The lower toxicity of the sulfoxides is probably attributable to the high rate of cleavage and elimination as glutathione conjugates
Some thiocarbamates (EPTC, Molinate, Pebulate, and Cycloate) share a common mechanism of toxicity, i.e. the inhibition of acetylcholinesterase. An acetylcholinesterase inhibitor suppresses the action of acetylcholine esterase. Because of its essential function, chemicals that interfere with the action of acetylcholine esterase are potent neurotoxins, causing excessive salivation and eye-watering in low doses. Headache, salivation, nausea, vomiting, abdominal pain and diarrhea are often prominent at higher levels of exposure. 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.

致癌物分类
对人类不具有致癌性(未列入国际癌症研究机构名录)。
No indication of carcinogenicity to humans (not listed by IARC).
Data concerning the effects of thiocarbamates on man are scarce. However, cases of irritation and sensitization have been observed among agricultural workers. Some thiocarbamates, e.g., molinate, have an effect on sperm morphology and, consequently, on reproduction. However, no teratogenic effects have been observed. The results of mutagenicity studies have shown that thiocarbamates containing dichloroallyl groups are highly mutagenic. Some thiocarbamates are acetylcholine esterase inhibitors. 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.
As with organophosphates, the signs and symptoms are based on excessive cholinergic stimulation. Unlike organophosphate poisoning, carbamate poisonings tend to be of shorter duration because the inhibition of nervous tissue acetylcholinesterase is reversible, and carbamates are more rapidly metabolized. Muscle weakness, dizziness, sweating and slight body discomfort are commonly reported early symptoms. Headache, salivation, nausea, vomiting, abdominal pain and diarrhea are often prominent at higher levels of exposure. Contraction of the pupils with blurred vision, incoordination, muscle twitching and slurred speech have been reported. (L795)
