The toxicity and carcinogenicity of aniline in humans and animals have been well documented. However, the molecular mechanism involved in aniline-induced liver toxicity and carcinogenesis remains unclear. In our research, primary cultured hepatocytes were exposed to aniline (0, 1.25, 2.50, 5.0 and 10.0 μg/mL) for 24 h in the presence or absence of N-acetyl-l-cysteine (NAC). Levels of reactive o...

Delftia tsuruhatensis AD9 was isolated as an aniline-degrading bacterium from the soil surrounding a textile dyeing plant. The gene cluster involved in aniline degradation was cloned from the total DNA of strain AD9 into Escherichia coli JM109. After shotgun cloning, two recombinant E. coli strains showing aniline oxidation activity or catechol meta-cleavage activity were obtained by simple pla...

This study was designed to compute the spectroscopic properties of aniline family, and educates the 3chloro-4-fluoro-aniline, which have unique pharmaceutical important. The structural and spectroscopic properties were investigated using a quantum calculation. The density functional theory approach at B3LYP/6–31G(d) data set is apply. IR and UV-Visible spectrophotometric estimated through GAMES...

A bacterial strain Pseudomonas sp. a3 capable of degrading nitrobenzene, phenol, aniline, and other aromatics was isolated and characterized. When nitrobenzene was degraded, the release of NH(4) (+) was detected, but not of NO(2) (-). This result implied that nitrobenzene might have a partial reductive metabolic pathway in strain a3. However, aniline appeared as one of the metabolites during th...

  Background and aims : Aniline as one of the aromatic amines is a widely distributed environmental pollutant resulting from the manufacture of dye materials and agricultural chemicals such as herbicides. It is frequently used by the industry such as the raw material in the manufacture of dyes, rubbers, pharmaceutical preparation, plastic and paint. It is also a common by product from paper and...

Background &Objectives: Aniline is a substance used in chemical industries and in various processes such as pesticide production, chemical bleaching, textile dyes, etc. In spite of the negative effects of aniline on the environment due the difficult decomposition of this substance, various methods have been investigated to remove this substance from water resources. The aim of this study was to...

Mutagenic/carcinogenic 9-(4'-aminophenyl)-9H-pyrido[3,4-b]indole [aminophenylnorharman (APNH)] is formed from norharman and aniline in the presence of cytochrome P450 3A4/1A2. Because both precursors are widely distributed in the environment, human exposure is unavoidable. To clarify APNH formation in the human body, amounts of the compound in 24-h human urine collected from smokers and nonsmok...

Electrochemical polymerization of aniline is one of the most promising methods to prepare polyaniline (PANI) materials. However, during this process, the electrolyte solution must be replaced after electropolymerization of a certain time because of the generation and the accumulation of the by-products, which have significant effects on the morphology, purity and properties of PANI products. Tr...

o-Benzenedisulfonimide (OBS) has efficiently catalysed the one-pot three-component reaction of ketones and aromatic amines with trimethylsilyl cyanide (TMSCN) giving the corresponding α-amino nitriles in excellent yields (23 examples; average yield 85%). Reaction conditions were very simple, green and efficient. Theoretical calculations have allowed us to explain the mechanism of this reaction ...
