aniline toxicity mechanism

Agmenellum quadruplicatum strain PR-6 and Oscillatoria sp. Further, extensive reanalysis of the previous proteomic data of aniline exposed cells revealed up-regulation of envelope stress response(ESR) proteins such as periplasmic protein folding, envelope integrity, transmembrane complex, and cell-wall remodelling proteins. Proteomic data reveal the up-regulation of envelope stress response proteins to aniline exposure. Animals were euthanized at 24 h following the last dose. Aniline caused mesenchymal tumors in the spleen of rats but not in mice after dietary chronic exposure. The free p50 and p65 and Jun/ Fos dimers translocate into nuclei and regulate transcription of a variety of genes including TNF, IL-1, IL-6 that finally induce inflammatory and fibrosis responses. 2018 Oct 31;140(43):14015-14018. doi: 10.1021/jacs.8b07366. Clipboard, Search History, and several other advanced features are temporarily unavailable. 2004;81(1):198–215. Aniline, phenylamine or aminobenzene is an organic compound with the formula C6H5NH2. EPA has classified aniline as a Group B2, probable human carcinogen. These investigators concluded that SCE production did not correlate well with oncogenic potential for aromatic amines and azo derivatives In other in vitro studies, aniline did not cause chromosomal damage m V-79 Chinese hamster cells incubated m the presence of a rat liver microsomal activating system (Swenberg et al 1976) As measured by an alkaline elution technique, aniline induced … Toxicology. The spleen toxicity of aniline is studied more and the different mechanisms are suggested. Aniline exposure leads to neuron and spleen toxicity specifically and makes diverse neurological effects and sarcoma that is defined by splenomegaly, hyperplasia, and fibrosis and tumors formation at the end. 2014;147(4):R105–R117. Mechanistic Study on Aniline-Induced Erythrocyte Toxicity. 2008 Jul 15;230(2):227-34. doi: 10.1016/j.taap.2008.02.022. The aniline compounds tested caused a relatively low oxidation rate of glutathione in the presence of horseradish peroxidase (HRP), and H2O2; however, they demonstrated marked oxygen consumption when a polyamine molecule was present.

Aniline-induced methemoglobinemia, loss of circulating blood cells, blood … Aniline derivatives were categorized into 5 subcategories based on their chemical structure and repeat-dose toxicity referring known toxicity mechanism. Data on carcinogenicity of aniline in humans are inadequate for an evaluation. Aniline can be toxic if ingested, inhaled, or by skin contact. HHS The doses were based on earlier studies that had shown spleen toxicity and carcinogenicity in male rats at 100 mg/kg/day but not at 10 mg/12/kg/day. Surprisingly, strain JA2 forms EPS only when exposed to aniline and other toxic compounds like organic solvents and heavy metals indicating that EPS formation is coupled to cell toxicity. The LOAEL was converted to the equivalent of aniline (7 mg/kg-day) and divided by an uncertainty factor of 1000 (10 for the use of a LOAEL, 10 to account for extrapolation from animal data and 10 to protect sensitive individuals) to derive the RfD. Schematic diagram depicting proposed mechanisms…, Schematic diagram depicting proposed mechanisms responsible for aniline inducedspleen toxicity. Rubrivivax benzoatilyticus JA2, an aniline non-degrading bacterium, tolerates high concentrations of aniline and produces extracellular polymeric substance (EPS). Ma H, Wang J, Abdel-Rahman SZ, Boor PJ, Khan MF. Rubrivivax benzoatilyticus JA2, an aniline non-degrading bacterium, tolerates high concentrations of aniline and produces extracellular polymeric substance(EPS). This condition is known as methemoglobinemia and its severity depends on how much you are exposed to and for how long. Germany)(Wiley-VCH Verlag GmbH & Co. KGaA, 2000. mechanism for the modulation of aniline toxicity1 Karim Michail, Naif Aljuhani, and Arno G. Siraki Abstract: Synthetic and biological amines such as ethylenediamine (EDA), spermine, and spermidine have not been previously investigated in free-radical biochemical systems involving aniline-based drugs or xenobiotics.
