35 % · about 35 % in water, less soluble in organic solvents. However, the free acid, diethyldithiocarbamic acid, is readily soluble in organic solvents and less soluble in water. Thus, on acidification of an aqueous solution of a diethyldithiocarbamate, the free acid can be extracted with chloroform or carbon tetrachloride. The distribution ratio is 2,360 for chloroform and 343 for carbon tetrachloride.

Interactions · 5 Einträge

Rats exposed to enflurane (100 ppm) or methoxyflurane (300 ppm) in a closed all glass system eliminated these anesthetics from atmosphere with half life of 6.84 hr for enflurane and 0.64 for methoxyflurane. Pretreatment with dithiocarb (100 mg/kg ip) prolonged elimination half life of both compounds.

Rat liver microsomes catalyze covalent binding of (14)C-carbon tetrachloride metabolites to the microsomal protein; this binding was inhibited by dithiocarb at an I50 (50% inhibition) of 2.3x10-5 moles. Dithiocarb effectively inhibited metabolic elimination of carbon tetrachloride at a dose of 100 mg/kg.

Dithiocarb increased T-cell associated responses in mice treated with azathioprine or hydrocortisone acetate. Such a beneficiary effect contrasted with its inefficiency to restore functions abrogated by cyclophosphamide. The results raise the possibility of developing a rational chemoimmunotherapy using dithiocarb with a compatible cytoreductive drug.

Sc injection of 0.5 mmoles dithiocarb, 30 min before an ip injection of 280 mg aniline- hydrocloric acid/kg, affected aniline toxicity to rats by increasing mortality from 41.6 to 75%, decreasing methemoglobin formation by 67.72%, and inhibiting hepatic aniline hydroxylase by 47.6%.

Toxicity Summary · 1 Eintrag

IDENTIFICATION AND USE: Sodium diethyldithiocarbamate (DETC) is a solid. It is used as corrosive inhibitor, rubber accelerator, intermediate, polymerization shortstop, and chemical intermediate in production of bis(thiocarbamoyl)sulfides (rubber-processing accelerators and fungicides). It is also used for colorimetric determination of small quantities of copper and for its separation from other metals, as well as spin trap (as FeDETC complex) for nitric oxide detection. DETC has also been used as a medication and antidote in nickel carbonyl exposures. HUMAN EXPOSURE AND TOXICITY: Allergic contact dermatitis from a wet suit was related to zinc diethyldithiocarbamate. ANIMAL STUDIES: Zinc diethyldithiocarbamate and DETC were positive in the murine local lymph node assay (LLNA). Administered systemically, DETC is reported to have caused detachment of the retina in dogs, but no damage to the retina in monkeys. In albino rats and beagle dogs, it caused no impairment of vision or structural alteration in the eye after daily administration for ninety days. In a 6-wk experiment in mice, daily sc injection of 50 mg/kg bw had marked anti-thyroid activity. DETC administered to rabbits at 100, 200, and 400 mg/kg daily for 4 weeks increased triglyceride and phospholipid levels. No changes were found in serum cholesterol concentration. DETC reduces blood copper concentrations. Pregnant rabbits injected intravenously with 0.5 g sodium diethyldithiocarbamate/day on 5 days per week throughout pregnancy failed to deliver litters. DETC elevated copper levels in the brain and peripheral nerve, leading to oxidative stress and lipid peroxidation from redox cycling of copper. Lipid peroxidation appears to either be a contributing event in the development of demyelination, possibly through an increase of redox active copper, or a consequence of the myelin injury. Continued DETC exposure induced an extensive degeneration of axons and myelin sheath (Wallerian degeneration in axons). DETC was not carcinogenic to rats or mice in NTP bioassay. Sodium diethyldithiocarbamate was negative when tested using Salmonella typhimurium strains (TA1535, TA1537, TA97, TA98 and TA100) in the presence and absence of metabolic activation. However, a small but significant increase in the number of chromosome breakages and aberrations was found in Vicia faba. DETC given orally to young and adult domestic fowl produced retarded testicular development, and produced degeneration in the seminiferous epithelium of mature birds. Nerve fiber degeneration was produced in the medulla and spinal cord of chicks. ECOTOXICITY STUDIES: DETC>3 mg/L applied to developing frog embryos was lethal in 24 hr. Between 1-3 mg/L caused severely malformed embryos. Retardation of growth, curvature of body axis, general edemic condition, pigmentation disorders, and abnormal notochords were noted.

Ecotoxicity Excerpts · 2 Einträge

/AQUATIC SPECIES/ The effects of intraperitoneal injection of diethyldithiocarbamate (DDC) on free radical processes were examined in brain, liver and kidney of goldfish (Carassius auratus). Levels of oxidatively modified lipids and proteins as well as the activities of antioxidant and associated enzymes were measured. Intraperitoneal injection of DDC at a concentration of 0.01 mg/g wet mass decreased SOD activities by about 30-50% after 48 and 168 hr compared to corresponding sham-injected values. This treatment resulted in transient oxidative stress. Lipid peroxide content increased after DDC injection at all time points in the kidney, after 48 hr in the liver and was elevated in most experimental groups in the brain. Thiobarbituric-acid reactive substances (end products of lipid peroxidation) rose within the first 48 hr after injection, but returned to initial levels after 168 hr. Two other indices of oxidative stress were also transiently modified: protein carbonyl levels in the brain and kidney increased 24 hr post-injection, and the low-molecular mass thiol content was reduced over the same period in all tissues examined. Activities of catalase, glutathione peroxidase, glutathione-S-transferase, glutathione reductase, and glucose-6-phosphate dehydrogenase showed differential responses to DDC treatment that rebounded by 168 hr post-injection. Glutathione peroxidase activities were reduced by 60, 45 and 65% in the brain, liver and kidney, respectively, after 24 hr but rebounded thereafter. After 48 hr post-injection with DDC significant decreases were also seen in liver and kidney catalase, GST activities in all three tissues, and kidney GR and G6PDH activities. In some cases, catalase, GST, GR and G6PDH activities transiently increased after 24 hr. It was concluded that DDC injection depleted SOD and simultaneously stimulated lipid peroxidation, but did not require compensatory enhancement of other enzymatic defenses. Different actions of the superoxide anion in cellular metabolism and possible consequences of the impairment of superoxide dismutase are discussed.

/AQUATIC SPECIES/ Sodium diethyldithiocarbamate concentration >3 mg/L applied to developing frog embryos were lethal in 24 hr. Between 1-3 mg/L caused severely malformed embryos. Retardation of growth, curvature of body axis, general edemic condition, pigmentation disorders, and abnormal notochords were noted.

Mechanism of Action · 2 Einträge

Although the ability of disulfiram to inactivate CYP2E1 has been known for more than 20 years, the mechanism has not yet been elucidated. A metabolite of disulfiram, diethyldithocarbamate (DDC), is converted by CYP2E1 to a reactive intermediate that subsequently inactivates the protein, leading to mechanism-based inactivation. Mass spectral analysis of the inactivated human 2E1 protein demonstrates that the inactivation is due to the formation of an adduct of the reactive metabolite of DDC with the apoprotein. These data, along with mass spectral analysis of a reactive intermediate trapped with GSH, indicate the involvement of a reactive intermediate with a molecular mass of 116 Da. Our results suggest that this binding involves formation of a disulfide bond with one of the eight cysteines in CYP2E1. The inactivation of wild-type CYP2E1 as well as two of its polymorphic mutants, CYP2E1*2 and CYP2E1*4, was also investigated. For wild-type CYP2E1, the K(I) was 12.2 uM and the k(inact) was 0.02 min(-1). The K(I) values for the two polymorphic mutants were 227.6 and 12.4 uM for CYP2E1.2 and CYP2E1.4, and the k(inact) values were 0.0061 and 0.0187 min(-1), respectively. These data indicate that DDC is a much less efficient inactivator of CYP2E1.2 than it is of either the wild-type or the CYP2E1.4 variant.

... DDTC significantly inhibited the activity of superoxide dismutase and the activity of gamma-glutamyl transpeptidase, glutathione reductase, and alkaline phosphatase, whereas an increase in the activity of glutathione peroxidase was found. The membranes of pneumocytes type II were injured.

Metabolism/MetabolitesIn rats, four metabolites, diethyldithiocarbamate, diethyldithiocarbamate-s-glucuronide, inorganic sulfate and carbon disulfide were identified; these are also metabolites of disulfiram.
MeSH Pharmacological Classification · 3 Einträge

Substances that augment, stimulate, activate, potentiate, or modulate the immune response at either the cellular or humoral level. The classical agents (Freund&apos;s adjuvant, BCG, Corynebacterium parvum, et al.) contain bacterial antigens. Some are endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Their mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy of many biological response modifiers is related to their antigen-specific immunoadjuvanticity.

Agents used in the prophylaxis or therapy of VIRUS DISEASES. Some of the ways they may act include preventing viral replication by inhibiting viral DNA polymerase; binding to specific cell-surface receptors and inhibiting viral penetration or uncoating; inhibiting viral protein synthesis; or blocking late stages of virus assembly.

Chemicals that bind to and remove ions from solutions. Many chelating agents function through the formation of COORDINATION COMPLEXES with METALS.

Absorption, Distribution and Excretion · 5 Einträge

Rats receiving levels of 500 mg of dithiocarb in 1-2 mL water/kg body weight by gavage reached plasma levels of 2 mg/L dithiocarb in 3 hours.

A half life for absorption of 26 minutes was determined when S-dithiocarb dissolved in 2M phosphate buffer was injected into the small intestinal lumen of adult male Wistar rats at a dose of 25 mg/kg.

Within 15 minutes of dosing rats with 25 mg (222 moles S)/rat S-dithiocarb i.p., nonprotein bound radiolabel was detected in the plasma (1561 nmoles/mL plasma) and in the liver (3211 nmoles/g liver). A substantial amount (>45% within 15 minutes of dosing) of radioactivity also was found to be bound reversibly to soluble proteins of liver and plasma.

A small amount (<0.1%) of unchanged dithiocarb was detected in the urine of rats receiving ip injections of 25 mg (35)S-dithiocarb/rat. One hr after dosing, 96.1% of the radiolabeled urinary metabolites was of S-glucuronide conjugate and 3.9% inorganic sulfate. Within 1 hr after dosing, 7% of the administered (35)S-dithiocarb was recovered as carbon disulfide in the expired air.
