Burkholderia sp. strain AK-5 utilized 4-aminophenol as the sole carbon, nitrogen, and energy source. A pathway for the metabolism of 4-aminophenol in strain AK-5 was proposed based on the identification of three key metabolites by gas chromatography-mass spectrometry analysis. Strain AK-5 converted 4-aminophenol to 1,2,4-trihydroxybenzene via 1,4-benzenediol. 1,2,4-Trihydroxybenzene 1,2-dioxyge...

Based on the dramatic accelerating effect of 2-aminophenol, three ligands derived from 2-aminophenol were developed. Copper-catalyzed coupling reaction of nitrogen-containing nucleophiles with aryl bromides was efficiently carried out under mild conditions using 1,2,3,4-tetrahydro-8-hydroxyquinoline as a novel, simple, and versatile ligand.

in this paper, absorption spectra of both solution and films of cyano azobenzene polymer are investigated. the analysis of overlapped absorption spectra of polymer, related to trans and cis isomers, shows that the population of cis isomers is higher than trans isomers. it means that, cyano azobenzene molecules have a folded structure in polymer, in thermal equilibrium. presence of cyano molecul...

This communication reports a nanocatalyst-based electrochemical assay for proteins. Ultrasensitive detection has been achieved by signal amplification combined with noise reduction: the signal is amplified both by the catalytic reduction of p-nitrophenol to p-aminophenol by gold-nanocatalyst labels and by the chemical reduction of p-quinone imine to p-aminophenol by NaBH4; the noise is reduced ...

Pseudomonas sp. strain AP-3 grows on benzoate, phydroxybenzoate, protocatechuate, and 2-aminophenol as sole carbon and energy source. This strain converted benzoate and p-hydroxybenzoate to catechol and protocatechuate respectively, which were metabolized via the ortho-cleavage pathway. The enzymes responsible for these reactions were shown to be inducible. In contrast, strain AP-3 constitutive...

In the reaction of m-aminophenol with carbohydrates in a thiourea/acetic acid reagent, addition of borate suppresses chromogen formation for hexoses and pentoses, and enhances it for disaccharides. All reaction products absorb maximally at 520 nm. The relatively greater intensity of the m-aminophenol/maltose reaction product was used in a saccharogenic method for amylase, with low blank reading...

The aims of this research are to synthesize and determine the formula, characteristics, complex structure Cu(II) Co(II) with 4-aminophenol investigate their antibacterial activity. complexes were synthesized by refluxing a solution CuSO4·5H2O CoSO4·7H2O, respectively, in methanol for 1 h. products characterized using UV-Vis spectroscopy, atomic absorption thermal analysis, conductivity, FTIR, m...

Sloane, Crane, and Mayer (2) reported that Mycobacterium smegmatis oxidizes aniline to p-aminophenol. It was also shown (2) that p-aminobenzoic acid (PABA) yields p-aminophenol after the PABA is first enzymatically decarboxylated to aniline. It is the purpose of this publication to present data on the effect of pH, citrate, inorganic ions, and inhibitors on this hydroxylation reaction. The data...

1. The metabolic effects of p-aminophenol have been compared with those of paracetamol and other analgesics in studies of rat liver and kidney in vitro. 2. p-Aminophenol injected into rats inhibited gluconeogenesis from lactate in renal cortical tubules, but not in isolated hepatocytes, and reduced kidney ATP content without affecting the ATP content of liver. Perfused kidneys from rats previou...
