OBJECTIVES Malondialdehyde (MDA), a lipid peroxidation by-product, has been widely used as an indicator of oxidative stress. Urinary 2-naphthol, a urinary PAH metabolite, is used as a marker of ambient particulate exposure and is associated with lung cancer and chronic obstructive pulmonary disease. However, the stability and intra-individual variation associated with urinary MDA and 2-naphthol...
Sulfur-limited batch enrichment cultures containing one of nine multisubstituted naphthalenesulfonates and an inoculum from sewage yielded several taxa of bacteria which could quantitatively utilize 19 sulfonated aromatic compounds as the sole sulfur source for growth. Growth yields were about 4 kg of protein per mol of sulfur. Specific degradation rates were about 4 to 14 mu kat/kg of protein....
naphthol isomers were simultaneously and spectrophotometrically determined in wastewater, using a model based on net analyte signal (nas). the calibration method used is a variation of the original hybrid linear analysis method as proposed by goicoechea and olivieri (hla/go). owing to spectral interferences, the simultaneous determination of mixtures of naphthol isomers, using a spectrophotomet...
Substrates that are specific for certain UDP-glucuronosyltransferase (UGT) isoforms are usually used as specific inhibitors to identify UGT isoforms responsible for the glucuronidation of drugs. 1-Naphthol and 4-nitrophenol are probe substrates for human UGT1A6. In the present study, we found that UGT1A1-catalyzed estradiol 3-O-glucuronide formation and UGT1A4-catalyzed imipramine N-glucuronide...
The title Schiff base compound, C(18)H(14)N(2)O(3), has an inter-mediate state between NH and OH tautomers. The mol-ecular structure is stabilized by an O-H⋯N hydrogen bond. The dihedral angle between the naphthalene ring system and the benzene ring is 37.44 (5)°.
Extraction of 2-(2-pyridylazo)-1-naphthol-4-sulfonate anion with solvated hydroxonium ion was carried out using 14 kinds of alcohols and 1-octanol/octane mixed solvents as a solvent at 25 degrees C. Alcohols are 1-pentanol, 1-hexanol, 1-heptanol, 2-heptanol, 3-heptanol, 4-heptanol, 1-octanol, 2-octanol, 3-octanol, 1-nonanol, 2-nonanol, 3-nonanol, 5-nonanol and 1-decanol. Among them, 1-octanol w...
Cyclization of hydrazones derived from 2-acetyl-1-naphthol and 1-acetyl-2-naphthol with triphosgene gave naphtho[1,2-e]-1,3-oxazines, naphtho[2,1-e]-1,3-oxazines or their spiro dimers depending on the molar ratio of triphosgene used for the cyclization.
