Glucuronidation of 1-naphthol in the rat intestinal loop

Biochemical Pharmacology, 1975
Abstract The glucuronidation of 1-naphthol after its instillation into the intestinal lumen was studied in closed or single pass perfused jejunal loops by measuring the appearance of 1-naphthol glucuronide in the intestinal lumen and in venous blood. Within 30 min 69% of 1-naphthol instilled into the jejunal loop was metabolized almost exclusively to

The activity of 1-naphthol-UDP-glucuronosyltransferase in the brain

Neuropharmacology, 1987
Cerebral microsomes catalysed efficiently the glucuronidation of 1-naphthol, this formation of glucuronide being activated by treatment with Triton X-100 or digitonin. Activated microsomes from the brain of the rat conjugated 1-naphthol with an apparent Km of 95 microM and a Vmax of 5.47 nmol/hr mg protein at 30 degrees C.

Sorption of 1-naphthol by plant cuticular fractions

Journal of Environmental Sciences, 2007
The contribution of aliphatic-rich plant biopolymer to sorption of hydrophobic organic compounds is significantly important because of their preservation and accumulation in the soil environment, but sorption mechanism is still not fully understood. In this study, sorption of 1-naphthol by plant cuticular fractions was examined to better understand the

Biotransformation of 1-Naphthol by a Strictly Aquatic Fungus

Current Microbiology, 2006
The aquatic hyphomycete Heliscus lugdunensis belongs to a group of exclusively aquatic mitosporic fungi with an only scarcely explored potential to oxidatively attack xenobiotic compounds, and was used to study the biotransformation of the environmental pollutant metabolite 1-naphthol. H. lugdunensis metabolized approximately 74% of 1-naphthol within 5

Degradation of carbaryl and 1-naphthol by marine microorganisms

Bulletin of Environmental Contamination and Toxicology, 1975
Carbaryl (l-naphthyl N-methylcarbamate), a carbamate insecticide with a wide range of activity and relatively low degree of toxicity to animals, is one of the most commonly used pesticides. It may enter the estuarine environment as a result of run-off from agricultural lands or through its use in the control of estuarine pests.

Intermolecular vibrations of 1-naphthol⋅NH3 and d3-1-naphthol⋅ND3 in the S and S1 states

The Journal of Chemical Physics, 2001
Hydrogen-bonded complexes of the photoacid 1-naphthol with NH3 and ND3 were investigated by resonant two-photon ionization, spectral hole burning, and fluorescence spectroscopies. Although the intermolecular vibrations are weak in both absorption and emission, with typical Franck–Condon factors <2% relative to the electronic origin, all six ...

Protolytic Photodissociation and Proton-Induced Quenching of 1-Naphthol and 2-Octadecyl-1-Naphthol in Micelles

The Journal of Physical Chemistry A, 2004
Kinetics of excited-state proton-transfer reactions and proton-induced fluorescence quenching of 1-naphthol (1N) and 2-octadecyl-1-naphthol (2O1N) in micellar solutions of cetyltrimethylammonium bromide (CTAB), polyoxyethylene(23) lauryl ether (Brij 35), and sodium dodecyl sulfate (SDS) was studied by using stationary and time-resolved fluorescence ...

A spectrophotometric determination of 1-naphthol in decimilligram amounts

Talanta, 1979
1-Naphthol is determined by spectrophotometric measurement at 510 nm after oxidation with vanadium(V) in approximately 4M hydrochloric acid and extraction of the oxidation product into toluene.

Radiolysis of 1-naphthol in aqueous solutions

Journal of Radioanalytical and Nuclear Chemistry, 2010
The effects of absorbed doses, initial pH and 1-naphthol concentration onto its radiolysis in aqueous sulphuric and hydrochloric acids by gamma rays from 60Co were investigated. Under the experimental conditions, 1-naphthol degradation yields increased with increasing the absorbed doses (0.3–3.0 kGy) and with decreasing the initial 1-naphthol ...

Tunable Formal Photocycloaddition of 1-Naphthol Derivatives

Journal of the American Chemical Society
Although three different modes of photocycloaddition between arenes and alkenes are well-known, the control of reaction selectivity remains a long-standing challenge. In this study, we present the first tunable photocycloaddition of 1-naphthol derivatives under visible light irradiation, affording ortho, meta, and para cycloadducts, respectively.
