Toxicity Profile
Route of ExposureDermal (L957
Mechanism of ToxicityAt least four mechanisms, possibly all functioning simultaneously. DDT reduces potassium transport across the membrane. DDT alters the porous channels through which sodium ions pass. These channels activate (open) normally but are inactivated (closed) slowly, thus interfering with the active transport of sodium out of the nerve axon during repolarization. DDT inhibits neuronal adenosine triphosphatases (ATPases), particularly Na+K+-ATPase, and Ca2+-ATPase which play vital roles in neuronal repolarization. DDT also inhibits the ability of calmodulin, a calcium mediator in nerves, to transport calcium ions that are essential for the release of neurotransmitters. All these inhibited functions reduce the rate of depolarization and increase the sensitivity of neurons to small stimuli that would not elicit a response in a fully depolarized neuron. (2)
MetabolismChlorobenzilate is metabolized by liver homogenates to para,para'-dichlorobenzilic acid; para, para'-dichlorobenzyhydrol; para-chlorobenzoic acid, and para, para'-dichlorobenzophenone. It is excreted in the urine (3).
Toxicity ValuesLD50: 2784-3880 mg/kg (Oral, Rat) (7) LD50: >10 000 mg/kg (Dermal, Rat) (7) LD50: >10 000 mg/kg (Dermal, Rabbit) (7)
Lethal DoseNot Available
Carcinogenicity (IARC Classification)3, not classifiable as to its carcinogenicity to humans. (6)
Uses/SourcesChlorobenzilate is used for mite control on citrus crops and in beehives. It has narrow insecticidal action, killing only ticks and mites (7).
Minimum Risk LevelNot Available
Health EffectsNervous tension, liver and kidney damage, abnormal electrical activity of the brain (2, 7, 3)
SymptomsSymptoms of chlrobenzilate poisoning include muscle pains, ataxia, mild delirium, fever, and mental status changes progressing to a tonic-clonic seizure. Nausea, vomiting, and diarrhea may follow ingestion (3, 1).
TreatmentIn case of ingestion, consider cautious gastric lavage; it must be weighed against potential complications of bleeding or perforation. Activated charcoal binds most toxic agents and can decrease their systemic absorption if administered soon after ingestion. In case of inhalation, move patient to fresh air. Monitor for respiratory distress, and 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. Irrigate exposed eyes with copious amounts of room temperature water for at least 15 minutes if the exposure occurred through eye contact. In case of dermal exposure, remove contaminated clothing and jewellery. Wash skin and hair thoroughly; do two soap and water washings. Leather absorbs pesticides. Hence, leather should not be worn in the presence of pesticides and all contaminated leather should be discarded. (4)

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.
