Biotransformation of trans-5-chloro-2-methyl-2,3,3a,12b-tetrahydro-1H- dibenz[2,3:6,7]oxepino[4,5-c]pyrrolidine maleate in rats

The metabolism of trans-5-chloro-2-methyl-2,3,3a-12b-tetrahydro-1H- dibenz[2,3:6,7]oxepino[4,5-c]pyrrolidine maleate (Org 5222) labelled with [3H] or [14C] was investigated in Wistar rats. Metabolites were identified by mass spectrometry, 13C- and 1H-NMR analysis, IR spectroscopy and, wherever possible, by comparison with authentic reference compounds. The metabolites found in plasma, bile, faeces and urine revealed the processes of metabolism in which Org 5222 underwent oxidation to yield an N-oxide existing in two diastereoisomeric forms, or N-demethylation to yield a demethyl metabolite. A novel metabolite was found in bile viz. a carbamate glucuronide, formed from an intermediate carbamic acid, derived from the addition of CO2 to the demethyl metabolite.
