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

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

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

1. Rat liver microsomal suspension containing NADPH and MgCl2 was incubated at 37 degrees C with naproxen, a non-steroidal anti-inflammatory drug. Thiobarbituric acid reactive substances (TBA-RS), high molecular weight protein aggregates and fluorescent substances were formed in the microsomal suspension.
