Route of Exposure | Oral (9) ; inhalation (9) ; dermal (9) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Mechanism of Toxicity | Unmetabolized carbon tetrachloride, depresses the central nervous system. All other toxic effects of carbon tetrachloride are related to its biotransformation via cytochrome P-450 enzymes, specifically CYP2E1. Metabolism of carbon tetrachloride by CYP2E1 may result in the destruction of the enzyme during the metabolic process, either by direct attack of radicals on the cytochrome(s) or highly localized lipid peroxidation resulting in detachment of P-450 proteins from the microsomal membranes. Reactive metabolites of carbon tetrachloride causes hepatic damage via haloalkylation of cellular macromolecules and lipid peroxidation. Carbon tetrachloride also perturbs the intracellular calcium homeostasis. Increased cytosolic levels of calcium may result from an influx of extracellular calcium caused by plasma membrane damage and decreased intracellular calcium sequestering. Higher levels of calcium activate enzymes such as proteases, which hydrolyze proteins in neighboring cells, leading to a progression of the lesion. Carbon tetrachloride's carcinogenicity is likely the result of certain reactive metabolites that bind to nuclear proteins, lipids, and DNA. (4, 9) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Metabolism | Carbon tetrachloride is absorbed readily from the gastrointestinal and respiratory tracts, and more slowly through the skin. It is distributed to all major organs, with highest concentrations in the fat, liver, bone marrow, adrenals, blood, brain, spinal cord, and kidney. Once carbon tetrachloride is absorbed, it is metabolized by cytochrome P-450 enzymes, with the production of the trichloromethyl radical. Aerobically, metabolism of the trichloromethyl radical can eventually form phosgene. Anaerobically, the radical can undergo reactions to form chloroform, hexachloroethane, or carbon monoxide. Carbon tetrachloride is excreted primarily in exhaled air and in the feces, with relatively minimal amounts in the urine.

Toxicity Values | LD50: 2800 mg/kg (Oral, Rat) (5) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Lethal Dose | 1700 to 1800 mg/kg for an adult human. (6) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Carcinogenicity (IARC Classification) | 2B, possibly carcinogenic to humans. (11) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Uses/Sources | Carbon tetrachloride was used in the production of refrigeration fluid and propellants for aerosol cans, as a pesticide, as a cleaning fluid and degreasing agent, in fire extinguishers, and in spot removers. (9) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Minimum Risk Level | Intermediate Inhalation: 0.03 ppm (10) Chronic Inhalation: 0.03 ppm (10) Acute Oral: 0.02 mg/kg/day (10) Intermediate Oral: 0.007 mg/kg/day (10) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Health Effects | High exposure to carbon tetrachloride can cause liver, kidney, and central nervous system damage. Single cell necrosis, which is evident after 5h to 6h after dosing, progresses to maximal centrilobular necrosis within 24h to 48h. Cellular regeneration is maximal 36h to 48h after dosing. The rate and extent of tissue repair are important determinants of the ultimate outcome of liver injury. In severe cases, coma and even death may occur. (4, 9) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Symptoms | Carbon tetrachloride exposure causes headaches, dizziness, sleepiness, nausea, and vomiting. (9) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Targets
- General Function:
- Zinc ion binding
- Specific Function:
- Nuclear hormone receptor. The steroid hormones and their receptors are involved in the regulation of eukaryotic gene expression and affect cellular proliferation and differentiation in target tissues. Ligand-dependent nuclear transactivation involves either direct homodimer binding to a palindromic estrogen response element (ERE) sequence or association with other DNA-binding transcription factors, such as AP-1/c-Jun, c-Fos, ATF-2, Sp1 and Sp3, to mediate ERE-independent signaling. Ligand binding induces a conformational change allowing subsequent or combinatorial association with multiprotein coactivator complexes through LXXLL motifs of their respective components. Mutual transrepression occurs between the estrogen receptor (ER) and NF-kappa-B in a cell-type specific manner. Decreases NF-kappa-B DNA-binding activity and inhibits NF-kappa-B-mediated transcription from the IL6 promoter and displace RELA/p65 and associated coregulators from the promoter. Recruited to the NF-kappa-B response element of the CCL2 and IL8 promoters and can displace CREBBP. Present with NF-kappa-B components RELA/p65 and NFKB1/p50 on ERE sequences. Can also act synergistically with NF-kappa-B to activate transcription involving respective recruitment adjacent response elements; the function involves CREBBP. Can activate the transcriptional activity of TFF1. Also mediates membrane-initiated estrogen signaling involving various kinase cascades. Isoform 3 is involved in activation of NOS3 and endothelial nitric oxide production. Isoforms lacking one or several functional domains are thought to modulate transcriptional activity by competitive ligand or DNA binding and/or heterodimerization with the full length receptor. Essential for MTA1-mediated transcriptional regulation of BRCA1 and BCAS3. Isoform 3 can bind to ERE and inhibit isoform 1.

- General Function:
- Zinc ion binding
- Specific Function:
- Nuclear hormone receptor. Binds estrogens with an affinity similar to that of ESR1, and activates expression of reporter genes containing estrogen response elements (ERE) in an estrogen-dependent manner (PubMed:20074560). Isoform beta-cx lacks ligand binding ability and has no or only very low ere binding activity resulting in the loss of ligand-dependent transactivation ability. DNA-binding by ESR1 and ESR2 is rapidly lost at 37 degrees Celsius in the absence of ligand while in the presence of 17 beta-estradiol and 4-hydroxy-tamoxifen loss in DNA-binding at elevated temperature is more gradual.
