Abstract

Oxyphenbutazone was oxidized when incubated with acetone powder prepared from sheep vesicular gland microsomes or with lipoxygenase at pH 4 or 5. Oxidation also occurred at pH 8 or 9, if arachidonate or linoleate was added to either of the incubation mixtures. The oxygenated product was found to be identical with 4-hydroxyoxyphenbutazone, which was synthesized and analyzed by gas liquid chromatography and mass spectrometry. The oxygenated compound was not an inhibitor of prostaglandin biosynthesis.
