Abstract
The in vitro metabolism of 2-hydroxylamino-3-methylpyridine has been investigated using arochlor 1254 pretreated rat S9 mixtures. 2-Hydroxylamino-3-methylpyridine is rapidly converted to the parent amine 2-amino-3-methylpyridine. No further oxidation products of 2-hydroxylamino-3-methylpyridine (i.e. nitroso or nitro) were detected under the HPLC conditions used. This observation may explain our previous findings on the in vitro metabolism of 2-amino-3-methylpyridine where no hydroxylamino metabolite was detected.
