Identification
Common Name 1,2-Dichlorobenzene
Description 1,2-Dichlorobenzene (1,2-DCB), or ortho-dichlorobenzene, is an organic compound with the formula C6H4Cl2. This colourless liquid is poorly soluble in water but miscible with most organic solvents. 1,2-Dichlorobenzene contains two chlorine atoms connected to one benzene molecule. Most of the 1,2-DCB released into the environment is present as a vapor. 1,2-DCB can burn, but they do not burn easily. (R677, R872)

Toxicity Profile
Route of Exposure Inhalation (R873) ; oral (R873) ; dermal (R873)
Mechanism of Action 1,2-DCB was found to covalently bind to DNA, RNA, and proteins of liver, kidney, lung, and stomach. (R677)
Metabolism After absorption, 1,2-DCB ist distributed in blood, the urinary bladder, kidney, fat, and liver. The initial step in the metabolism of 1,2-DCB is metabolism by cytochrome P-450 isozymes, mainly P4502E1, to an active epoxide. This epoxide can either react directly with cellular components, be conjugated to glutathione or glucuronic acid, or be hydrolyzed to form 2,3-dichlorophenol or 3,4-dichlorophenol. The dichlorophenol metabolites can be further metabolized by conjugation with glutathione, glucuronic acid, or sulfate, or further oxidized to catechols. An additional oxidation to form dichlorohydroquinone metabolites has also been proposed. Microsomal studies have implicated cytochrome P-450, and particularly P4502E1, as a major component of 1,2-DCB metabolism, resulting in the formation of dichlorophenols, dichlorocatechols, and dichlorohydroquinones. 1,2-DCB is eliminated primarily in the urine as metabolites rather than as the parent compound. (R677)
Toxicity Values LD50: 500 mg/kg (Oral, Rat) (R677)
Lethal Dose Not Available
Carcinogenicity (IARC Classification) 3, not classifiable as to its carcinogenicity to humans. (R264)
Uses/Sources Exposure may result from breathing contaminated air, drinking contaminated water or eating contaminated food, and skin contact. (R677)
Minimum Risk Level Acute Oral: 0.7 mg/kg/day (Rat and Mouse) (R260) Intermediate Oral: 0.6 mg/kg/day (Rat and Mouse) (R260) Chronic Oral: 0.3 mg/kg/day (Rat and Mouse) (R260)
Health Effects Inhaling the vapor or dusts of 1,2-DCB at very high concentrations could be very irritating to eyes and nose and cause burning and tearing of the eyes, coughing, difficult breathing, and an upset stomach. Ingestion of 1,2-DCB can cause effects in the kidneys and blood, and that 1,3-DCB caused thyroid and pituitary effects. (R677)
Symptoms Cough, drowsiness, sore throat and unconsciousness can result from inhalation. Burning sensation, diarrhoea, nausea and vomiting can follow ingestion. In case of dermal or eye exposure, redness and pain of the exposed surface can occur. Moreover, skin exposure can cause skin dryness. (R873)
Treatment Following oral exposure, administer charcoal as a slurry; administer oxygen to all cyanotic or symptomatic patients. In case of methemoglobinemia, administer 1 to 2 mg/kg of 1% methylene blue slowly IV in symptomatic patients; also consider adjunctive therapy. In case of inhalation exposure, move patient to fresh air; monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with inhaled beta2 agonist and oral or parenteral corticosteroids. Following eye exposure, irrigate exposed eyes with copious amounts of room temperature water for at least 15 minutes. Following dermal exposure, skin should be thoroughly washed with soap and water; contaminated clothing and shoes should be discarded. Administer 100 percent humidified supplemental oxygen with assisted ventilation as required. Treat for methemoglobinemia and sequelae. Signs and symptoms of methemoglobinemia may be delayed. (R383)

28. Plasma membrane calcium-transporting ATPase 4

This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the transport of calcium out of the cell.

This organochloride inhibits Na+/K+ ATPase and Ca2+ and Mg2+ ATPase, which are essential for the transport of calcium across membranes. This results in the accumulation of intracellular free calcium ions, which promotes release of neurotransmitters from storage vesicles, the subsequent depolarization of adjacent neurons, and the propagation of stimuli throughout the central nervous system.

40. Estrogen receptor

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. Isoform 3 can bind to ERE and inhibit isoform 1.

41. Estrogen receptor beta

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. 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.
