[Biotransformation and pharmacokinetics of beta-methyl-(1,1'-biphenyl)-4-propanenitrile (LU 20,884) in rats. Spectroscopic studies].

Several compounds of comparison have been examined by their spectroscopic behavior in mass-, 1H-NMR- and IR-spectra of the antiphlogistic active beta-methyl[1,1'-biphenyl]-4-propanenitrile (LU 20,884). Characteristic fragments of alkyl-substituted biphenyls could be determined as well as the localisation of hydroxylated products in 1H-NMR-spectra.
