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 ...

A novel metal complexes Cu (II), Co Cd Ru (III) from azo ligand 5-((2-(1H-indol-2-yl) ethyl) diazinyl)-2-aminophenol were synthesized by simple substitution of tryptamine with 2-aminophenol. Structures all the newly compounds characterized FT IR, UV-Vis, Mass spectroscopyand elemental analysis. In addition measurements magnetic moments, molar conductance and atomic absorption. Then study their ...

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...

O- or N-arylated aminophenol products constitute a common structural motif in various potentially useful therapeutic agents and/or drug candidates. We have developed a complementary set of Cu- and Pd-based catalyst systems for the selective O- and N-arylation of unprotected aminophenols using aryl halides. Selective O-arylation of 3- and 4-aminophenols is achieved with copper-catalyzed methods ...

In oder to discover potentially active antibacterial compounds, three Schiff bases: 2[(4-methoxybenzylidene)-amino]phenol (5), 2-[(3,4-dimethoxybenzylidene)-amino]phenol (6), 2-[(3,4,5-trimethoxybenzylidene)-amino]phenol (7), were synthesized by the condensation of 2-aminophenol (1) with aldehydes (2-4) in methanol along with H2SO4. The synthesized Schiff bases (5-7) were characterized by H-NMR...

1. A precocious development of UDP-glucuronosyltransferase activity (EC 2.4.1.17) towards o-aminophenol is demonstrated in 15-17 day foetal rat liver in utero after dexamethasone administration to the mother. 2. This stimulation of liver transferase activity in utero is directly proportional to the dose of dexamethasone infected. 3. Precocious development of transferase activity in utero can al...

Oor N-arylated aminophenol products constitute a common structural motif in various potentially useful therapeutic agents and/or drug candidates. We have developed a complementary set of Cuand Pd-based catalyst systems for the selective Oand N-arylation of unprotected aminophenols using aryl halides. Selective O-arylation of 3and 4-aminophenols is achieved with copper-catalyzed methods employin...

The expeditious synthesis of 2-aryl-benzothia/(oxa)zoles was carried out by the condensation of 2-aminothiophenol/2-aminophenol and diverse aryl aldehydes in presence of Acacia concinna as a biocatalyst under microwave irradiation. The catalytic process is associated with excellent yields, greener reaction conditions and the environmentally friendly microwave technique which are the st...
