5.4 Absorption, Distribution and Excretion

Tetramethylthiuramdisulfide appears to be readily absorbed through the intestinal tract and the lungs and is quickly and widely distributed throughout the body.

O'Donoghue, J.L. (ed.). Neurotoxicity of Industrial and Commercial Chemicals. Volume II. Boca Raton, FL: CRC Press, Inc., 1985., p. 48

In 2 days following its ingestion, bis(dimethylthiocarbamoyl) disulfide (TMTD) is found in the liver and spleen together with its metabolites: amine salt dimethyldithiocarbamic acid (DDCA) and tetramethylthiourea, and in the lungs, carbon disulfide and the amine salt of DDCA. TMTD is known to form N-nitrosodimethylamine by reaction with nitrite in mildly acid solution. TMTD and the amine salt of DDCA are excreted from the body in the urine and feces, and as carbon disulfide via the lungs.

Sheftel, V.O.; Indirect Food Additives and Polymers. Migration and Toxicology. Lewis Publishers, Boca Raton, FL. 2000., p. 551

After absorption (respiratory, dermal, gastrointestinal), thiram is distributed in all organs and is mainly excreted unchanged in urine and feces. Some metabolism exists; carbon dioxide is exhaled and dithiocarbamate is excreted in urine.

American Conference of Governmental Industrial Hygienists. Documentation of Threshold Limit Values for Chemical Substances and Physical Agents and Biological Exposure Indices for 2001. Cincinnati, OH. 2001., p. 3

5.5 Metabolism/Metabolites

In studies with ruminant animals fed corn treated with thiram, rumen microorganisms degraded thiram to carbon disulfide and probably hydrogen sulfide and dimethylamine. ... some unchanged thiram was also observed in feces /and/ urine.

Menzie, C.M. Metabolism of Pesticides. U.S. Department of the Interior, Bureau of Sport Fisheries and Wildlife, Publication 127. Washington, DC: U.S. Government Printing Office, 1969., p. 310

Pesticides and nitrites in food may be a hazard to man, since many pesticides are secondary or tertiary amines, which form nitroso compounds in the presence of nitrite under conditions resembling those in the human stomach. Compounds were incubated for 4 hours at 37 C in the presence of excess nitrite at pH 3. Thiram converted to the carcinogen dimethylnitrosamine at a yield of 9%.

PMID:7518 Egert G, Greim H; Food Cosmet Toxicol 14 (3): 193-5 (1976)

The major metabolite in plants is ethylene thiourea, followed by ethylene thiuram monosulfide and presumably ethylene thiuram disulfide and sulfur.

Hartley, D. and H. Kidd (eds.). The Agrochemicals Handbook. 2nd ed. Lechworth, Herts, England: The Royal Society of Chemistry, 1987., p. A399/Aug 87

The hepatotoxic effects of thiram metabolism to carbon disulfide were investigated in rats. Male Sprague-Dawley rats were administered 15, 30 or 60 mg/kg thiram ip. Activities of serum glutamic oxaloacetic transaminase and sorbitol dehydrogenase were measured in the blood to assess the extent of liver injury. Detectable amounts of carbon disulfide appeared after 1.5 to 2 hr of treatment; 5 hr were required for complete recovery of carbon disulfide produced from 60 mg/kg thiram. A 2 fold increase in the dose of thiram from 15 to 30 mg/kg resulted in a 10 fold increase in the amount of carbon disulfide in expired air. Increasing the thiram dose 4 times to 60 mg/kg resulted in a 40 fold increase in carbon disulfide production over that from a 15 mg/kg thiram dose. The microsomal inhibitor SKF-525A inhibited the formation of carbon disulfide from thiram; phenobarbital treatment increased the formation of carbon disulfide. Thiram caused a significant loss of cytochrome P450 and benzphetamine-N-demethylase activity at 24 hr following treatment. Five hours after 60 mg/kg thiram treatment, there was an increase in sorbitol dehydrogenase activity 47%; serum glutamic oxaloacetic transaminase activity increased by 41 and 40% during 5 and 24 hr, respectively. /It was/ concluded that carbon disulfide is an in vivo metabolite of thiram and may be responsible for hepatotoxicity.

PMID:3953292 Dalvi RR, Deoras DP; Acta Pharmacologica et Toxicologica 58 (1): 38-42 (1986)

5.6 Mechanism of Action

Inhibition of hepatic dehydrogenases results in an acetaldehyde reaction on exposure to ethanol. Other effects may result from the known reactions of dithiocarbamates with metals, sulfhydryl-containing enzymes, or metabolism to reactive metabolites including carbon disulfide.

O'Donoghue, J.L. (ed.). Neurotoxicity of Industrial and Commercial Chemicals. Volume II. Boca Raton, FL: CRC Press, Inc., 1985., p. 48

...Ingestion of the fungicide thiram (125 mg/kg)... /has/ been reported to evoke ovarian atrophy and cessation of egg laying in hens, presumably through inhibition of dopamine beta-hydroxylase.

... /It was/ previously demonstrated that Disulfiram impairs the permeability of inner mitochondrial membrane (IMM). In this report, the effect of Disulfiram and its structural analogue thiram (Th) on mitochondrial functions was studied in detail. /It was/ found that mitochondria metabolize thiram disulfide compounds (TDs) in a NAD(P)H- and GSH-dependent manner. At the concentration above characteristic threshold, TDs induced irreversible oxidation of NAD(P)H and glutathione (GSH) pools, collapse of transmembrane potential, and inhibition of oxidative phosphorylation. The presence of Ca(2+) and exhaustion of mitochondrial glutathione (GSH+GSSG) decreased the threshold concentration of TDs. ... TDs induced the mitochondrial permeability transition (MPT).
