Elevated expression of cyclins, cyclin-dependent kinases (CDKs) and phosphorylation of pRB protein along with increases in A, B and CDK1 as a cell cycle regulatory proteins cyclins, and reduce in CDK inhibitors (p21 and p27) could be critical in cell cycle regulation, which contributes to tumorigenic response after aniline exposure. Consisting of an amine attached to a benzene ring, aniline is the prototypical aromatic amine. aniline dihydrofluoride.

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. Rubrivivax benzoatilyticus JA2, an aniline non-degrading bacterium, tolerates high concentrations of aniline and produces extracellular polymeric substance(EPS). 2006;210(1-2):86–93.

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. aniline hydrogen iodide. 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. The primary toxicity of aniline is characterized by methemoglobinemia (Anon., 2001). Toxicol. 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. Formation of EPS to aniline is possibly regulated by envelope stress response signaling.  |  aniline diphosphate (1:1) aniline diphosphate (3:1) aniline diphosphate (4:1) aniline hydrobromide. 2018 Oct 31;140(43):14015-14018. doi: 10.1021/jacs.8b07366. The study suggests that aniline is an acute envelope stressor . Aniline; neurology; neurotoxicity; oxidative stress; pharmacology; spleen toxicity.. Copyright© Bentham Science Publishers; For any queries, please email at [email protected]. NIH Aniline derivatives were categorized into 5 subcategories based on their chemical structure and repeat-dose toxicity referring known toxicity mechanism. Aniline is synthesized by catalytic hydrogenation of nitrobenzene or by ammonolysis of phenol. The increased production of methemoglobin (MetHb) in erythrocytes (ferrihemoglobin HbFe3+) results from the oxidation of heme iron from the ferrous to the ferric state (Kiese, 1974; McLean et al., 1969). COVID-19 is an emerging, rapidly evolving situation. Activation of oxidative stress-responsive signaling pathways in early splenotoxic response of aniline. Repeated dose toxicity studies demonstrated that splenic toxicity of aniline is clearly associated with damage of erythrocytes in that the spleen is the organ responsible for the erythrocyte clearance. Embryol. 2013 Mar 15;267(3):276-83. doi: 10.1016/j.taap.2013.01.005. Mechanism-based or time-dependent P 450 inhibitors pose an addnl. Animals were euthanized at 24 h following the last dose. It causes headache, drowsiness, cyanosis, and mental confusion, and, in severe cases, can cause convulsions. Mechanistic Study on Aniline-Induced Erythrocyte Toxicity. Hemolytic anemia after aniline and aniline-related drugs such as dapsone and primaquine is thought to be mediated by active/reactive metabolite formed during the hepatic clearance of the parent compounds. The toxicity of aniline derivatives towards Agmenellum quadruplicatum strain PR-6 indicated that the cyanobacterium was extremely sensitive to o-, m- and p-aminophenols, and phenylhydroxylamine. Genotoxicity The statement regarding the classification and labelling of aniline may need to be revised in the light of new data announced to the CMR Working Group by Industry. toxicity of aniline after inhalation exposure is insufficient, but haematotoxicity at very low concentrations (19-66 mg/m3) have been reported for rats. USA.gov. 2 Mechanism of Action 2.1 Primary effects: erythrocytes The effects of aniline are manifest primarily in the erythrocytes in the form of the dose-related formation of methaemoglobin. risk of idiosyncratic drug toxicity since the mechanism of time-dependency often involves the formation of reactive metabolites, which can react with proteins other than the P 450 isoenzyme responsible for catalysis.
