title: Biotransformation of beta-nortestosterone by cultured porcine hepatocytes.
abstract: The metabolism of beta-nortestosterone by porcine hepatocytes was investigated. Initially beta-nortestosterone was rapidly oxidized to norandrostenedione, which was further transformed into a number of more hydrophilic compounds. It is assumed that most of these compounds were glucuronides, considering the effect of beta-glucuronidase treatment. The main product of enzymatic cleavage was investigated by gas chromatography-mass spectrometry but could not be identified until now.
