abstract: The metabolism of the antiphlogistic beta-methyl[1,1'-biphenyl]-4-propanenitrile (LU 20884) was investigated in urine after oral application in male Wistar-rats. Metabolite with the major share was alpha-hydroxy-4'-methoxy-alpha-methyl[1,1'-biphenyl]- 4-aceticacidmethylester, which could be identified by mass and 1H-NMR spectroscopy as derivative of diazomethane. Furthermore the following metabolites could be detected as 4'-methoxy-beta-methyl[1,1'-biphenyl]-4-propanoicmethylester and propanenitrile.
