O-desmethylnaproxen (2-(6-hydroxynaphthalen-2-yl)propanoic acid) was identified in 10 different water samples from Germany and Pakistan. In the Pakistan samples it was found in all samples, surface water and effluents, exhibiting estimated concentrations between 0.04 and 1.36 microg/L. In Germany it was

To characterize the kinetics of S-naproxen ('naproxen') acyl glucuronidation and desmethylnaproxen acyl and phenolic glucuronidation by human liver microsomes and identify the human UGT isoform(s) catalysing these reactions. Naproxen and desmethylnaproxen glucuronidation were investigated using microsomes from six and five

Interference by naproxen in the spectrophotometric assay for urinary 5-hydroxyindoleacetic acid has been investigated. Gas chromatography-mass spectrometry demonstrated that ingestion of naproxen was associated with the production of four urinary components, unchanged drug and three metabolites, the major one being

The metabolites of naproxen produced by Cunninghamella species were isolated and identified, and further to compare the similarities between microbial transformation and mammalian metabolism. Naproxen was transformed by three strains of Cunninghammella species (Cunninghamella blakeslesna AS 3.153, Cunninghamella echinulata AS
