Common NameTetrabutyltin
ClassSmall Molecule
DescriptionTetrabutyltin is an organotin compound. It is the starting material of the tributyltin and dibutyltin compounds, which are used as stabilizers for PVC, biocides, fungicides, and anti-biofouling agents. Tin is a chemical element with the symbol Sn and atomic number 50. It is a natural component of the earth's crust and is obtained chiefly from the mineral cassiterite, where it occurs as tin dioxide.

Toxicity Profile
Route of ExposureOral (4) ; inhalation (4) ; dermal (4)
Mechanism of ToxicityOrganotin compounds produce neurotoxic and immunotoxic effects. Organotins may directly activate glial cells contributing to neuronal cell degeneration by local release of pro-inflammatory cytokines, tumor necrosis factor-_, and/or interleukins. They may also induce apoptosis by direct action on neuronal cells. Organotin compounds stimulate the neuronal release of and/or decrease of neuronal cell uptake of neurotransmitters in brain tissue, including aspartate, GABA, glutamate, norepinephrine, and serotonin. This may be either a contributing factor to or result of the neuronal cell loss. The immunotoxic effects of organotins are characterized by thymic atrophy caused by the suppression of proliferation of immature thymocytes and apoptosis of mature thymocytes. Organotin compounds are believed to exert these effects by suppressing DNA and protein synthesis, inducing the expression of genes involved in apoptosis (such as nur77), and disrupting the regulation of intracellular calcium levels, giving rise to the uncontrolled production of reactive oxygen species, release of cytochrome c to the cytosol, and the proteolytic and nucleolytic cascade of apoptosis. The suppression of proliferation of immature thymocytes further results in the suppression of T-cell-mediated immune responses. Organotins are also endocrine disruptors and are believed to contribute to obesity by inappropriate receptor activation, leading to adipocyte differentiation. Inorganic tin triggers eryptosis, contributing to tin-induced anemia. (4, 1, 2)
MetabolismThough tin metal is very poorly absorbed, tin compounds may be absorbed via oral, inhalation, or dermal routes, with organotin compounds being much more readily absorbed than inorganic tin compounds. Tin may enter the bloodstream and bind to hemoglobin, where it is distributed and accumulates mainly in the kidney, liver, lung, and bone. Organotin compounds may undergo dealkylation, hydroxylation, dearylation, and oxidation catalyzed by cytochrome P-450 enzymes in the liver. The alkyl products of dealkylation are conjugated with glutathione and further metabolized to mercapturic acid derivatives. Tin and its metabolites are excreted mainly in the urine and feces. (4)

Carcinogenicity (IARC Classification)No indication of carcinogenicity to humans (not listed by IARC).
Uses/SourcesTetrabutyltin is the starting material of the tributyltin and dibutyltin compounds, which are used as stabilizers for PVC, biocides, fungicides, and anti-biofouling agents. (6)
Minimum Risk LevelNot Available
Health EffectsBreathing or swallowing, or skin contact with organotins, can interfere with the way the brain and nervous system work, causing death in severe cases. Organic tin compounds may also damage the immune and reproductive system. (3, 4)
SymptomsInorganic or organic tin compounds placed on the skin or in the eyes can produce skin and eye irritation. (4)

Targets

General Function:
Zinc ion binding
Specific Function:
Nuclear receptor that binds peroxisome proliferators such as hypolipidemic drugs and fatty acids. Once activated by a ligand, the nuclear receptor binds to DNA specific PPAR response elements (PPRE) and modulates the transcription of its target genes, such as acyl-CoA oxidase. It therefore controls the peroxisomal beta-oxidation pathway of fatty acids. Key regulator of adipocyte differentiation and glucose homeostasis. ARF6 acts as a key regulator of the tissue-specific adipocyte P2 (aP2) enhancer. Acts as a critical regulator of gut homeostasis by suppressing NF-kappa-B-mediated proinflammatory responses. Plays a role in the regulation of cardiovascular circadian rhythms by regulating the transcription of ARNTL/BMAL1 in the blood vessels (By similarity).

General Function:
Zinc ion binding
Specific Function:
Receptor for retinoic acid. Retinoic acid receptors bind as heterodimers to their target response elements in response to their ligands, all-trans or 9-cis retinoic acid, and regulate gene expression in various biological processes. The RXR/RAR heterodimers bind to the retinoic acid response elements (RARE) composed of tandem 5'-AGGTCA-3' sites known as DR1-DR5. In the absence of ligand, the RXR-RAR heterodimers associate with a multiprotein complex containing transcription corepressors that induce histone acetylation, chromatin condensation and transcriptional suppression. On ligand binding, the corepressors dissociate from the receptors and associate with the coactivators leading to transcriptional activation. RARA plays an essential role in the regulation of retinoic acid-induced germ cell development during spermatogenesis. Has a role in the survival of early spermatocytes at the beginning prophase of meiosis. In Sertoli cells, may promote the survival and development of early meiotic prophase spermatocytes. In concert with RARG, required for skeletal growth, matrix homeostasis and growth plate function (By similarity). Regulates expression of target genes in a ligand-dependent manner by recruiting chromatin complexes containing KMT2E/MLL5. Mediates retinoic acid-induced granulopoiesis.
